3,774,501	Nov. 27, 1973	Thread Milling Attachment	Roger W. Brown	Windsor, Windsor County, VT	Abstract: A thread milling attachment adapted to be mounted in place of a conventional cross slide on a machine tool to make use of the standard mechanism for feeding the thread cutter radially to the desired depth and rotating the cutter in normal manner by conventional attachment gearing. The tool slide for the cutter spindle is separately mounted from the lead screw thus allowing the cutter spindle to travel at an angle relative to the axis of the work spindles while the lead screw remains substantially parallel to the work spindle axes. Axial movement of the thread milling attachment may also be obtained to move the cutter axially relative to the work into position preparatory to feeding the cutter into the work and to move the drive pinion for the lead screw into engagement with a face gear on one of the work spindles.

3,872,626	Mar. 25, 1975	Grinding Machine with Tilting Table	Philip H. White	Claremont, Sullivan County, NH	Abstract: A grinding machine of the vertical spindle, rotary chuck, sliding table type introduces a selective offset between the normally precisely aligned orientation of the table relative to the grinding axis by lifting the table from one way for rotation on the other way about a fixed center of rotation.
3,970,830	Jul. 20, 1976	Computer Controlled Machine Tool Contouring System	Philip H. White	Claremont, Sullivan County, NH	Abstract: A computer controlled machine tool contouring system having a cutting element which is positioned relative to a workpiece support table. An actuating means controls the workpiece support table to synchronously rotate about a first axis and slide along a second axis in response to a set of control signals. The actuating means further controls the cutting element to translate along a third axis (the third axis being parallel to the first axis and perpendicular to the second axis) in response to a further set of control signals. The control signals are generated by a control means from stored data signals which are representative of the coordinates of points on the desired workpiece contour, the desired pressure angle of the cutting element at each contour point, the current radius of the cutting element, and the desired cutting element motion along the third axis. The control means includes (1) a mini-computer programmed to establish overall system control and to transform input data signals to suitable form for subsequent processing, (2) a high speed computation network for generating digital control signals for driving the actuating means, and (3) an interface unit for transferring digital control signals between the computer, computation network, machine tool and an operator station. The signal processing performed by the mini-computer and the computation network is arranged in accordance with a programmed algorithm to provide control signals for directing the actuating means to position the workpiece support table and cutting element in a manner to accommodate a cutting element having a changing radius due to wear. In addition, the control signals produce (in accordance with the programmed algorithm) directed movement of the contact point of the cutting element relative to a point on the workpiece contour at a predetermined surface velocity and feedrate.

4,253,359	Mar. 03, 1981	Drive System for Multiple Spindle Machine Tool	David H. Youden	Cornish, Sullivan County, NH	Abstract: A drive system for a multiple spindle machine tool which includes a separate servo motor for powering the drum shaft which serves as the basic control element for the timing and movement of tools which are operable upon the workpieces carried in the spindles. The speed of the servo motor is regulated by a tachometer in a feedback loop to hold the speed of the motor at any chosen value. The drum shaft rotates at either high speed during tool traverse or low or feed speed during machining operations. A second tachometer driven by the spindle drive system generates a signal proportional to the spindle speed and that signal coordinates the low feed speed of the drum shaft with the spindle speed. Conventional clutches for high-speed and reverse operation of the drum shaft are replaced by switches and potentiometers.
4,267,495	May. 12, 1981	Machine Speed Controller	Bernard W. Wilterdink	Claremont, Sullivan County, NH	Abstract: To initiate a scheduled speed change at the correct point in the operating cycle of a machine, a speed change command is subjected to a variable delay. Attaining the commanded speed level too early or too late in one cycle results in the speed change command being correspondingly delayed or advanced in the next cycle. In the preferred embodiment, a low point controller is designed to control the high-to-low speed transition in a multiple spindle bar or screw machine to achieve "feed" speed at the optimum point to decrease cycle time while avoiding damage to the cutting tools.
4,402,032	Aug. 30, 1983	Electromagnet Power Supply and Demagnetizer	Bernard W. Wilterdink	Claremont, Sullivan County, NH	Abstract: An electronic current control device for energizing and de-energizing an electromagnet, such as a magnetic chuck, includes a DC power source preferably in the form of a phase-controlled SCR power unit. A conduction angle control signal is routed to positive or negative gates in the power unit to determine polarity and amplitude of direct current through the electromagnet windings. In the "on" mode an analog current feedback loop maintains a predetermined magnetizing level of current through the windings. In the demagnetize mode, a digital system decreases the current amplitude stepwise while alternating the polarity. When the sensed current attains the selected peak level for a given step, a digital count is decremented. The polarity is reversed according to the odd or even count, and a new peak reference level is established corresponding to the digital count.
5,807,162	Sep. 15, 1998	Grinding Apparatus, and Process for the Operation Thereof	Alden P. Dana	Hartland, Windsor County, VT	Abstract: A grinding apparatus comprises a table having a first bearing surface; a chuck mounted on the table for rotation about a chuck axis and provided with means for holding a workpiece, the chuck having on its underside a second bearing surface, such that when the chuck is stationary, the second bearing surface rests on the first bearing surface; a grinding head having a least one grinding surface capable of grinding a workpiece mounted on the table, the grinding head being mounted for rotation about a head axis substantially parallel to the chuck axis; and transport means for moving the chuck relative to the grinding head in both directions along a transport axis substantially perpendicular to both the chuck axis and the head axis. To allow rotation of the chuck to begin smoothly, the apparatus has lubricating means provided on the table for introducing a lubricating fluid under super-atmospheric pressure between the table and the chuck, thereby causing the chuck to lift away from the table; and control means arranged to first introduce the lubricating fluid through the lubricating means while the chuck is not rotating relative to the table, and thereafter to cause the chuck to rotate relative to the table.
