  • Patent number: 4167837
    Abstract: A method and apparatus are disclosed for grinding a surface upon a workpiece having disparate grindability characteristics. A mechanical cam is used in the preferred embodiment to model the characteristics of a cylindrical surface and is rotated with the workpiece. The cam imparts motion to a follower which in turn imparts the motion to a pulse generator. Electrical signals which are dependent upon the angular orientation of the workpiece and the grindability characteristics of a circumferential sector of the workpiece in grinding contact with an abrasive wheel are produced by the pulse generator and used to partially control the infeed movement and the interface force between the workpiece and the abrasive wheel.

  • Patent number: 4164391
    Abstract: A conveyor apparatus for carrying workpieces on flat trays has two parallel chains with tray supports connected at equal intervals between the two chains. Each tray support has a clamping device for clamping and releasing flat silicone rubber covered trays against itself. Cams are located between the chains to operate the clamping device to release the tray (for travel through a separate path) at one point in travel and later (when the tray returns from its separate path) to clamp it again. The conveyor is shown as combined with up-and-down elevator means in an oven to give a boustrophedontic path to a plurality of workpieces being heated on trays in the oven: the trays are released and clamped at the entrance to and exit from the oven to allow movement of the trays by the elevators through up and down paths at the release and clamping stations.

  • Patent number: 4163581
    Abstract: A base member is mounted on the driven element of a mining machine or the like. A bit holder is affixed to the base member in such a way that the bit holder may be readily removed and replaced. The base member and bit holder having cooperating abutment surfaces to sustain much of the resultant cutting forces encountered during operation. A connecting pin is provided to maintain the bit holder in position on the base member. Retaining means are provided for the connecting pin. Such retaining means are located between the ends of the connecting pin so as to lock the connecting pin in position without having to have either the connecting pin or the retaining means extend laterally from the joined bit holder and base member. The connecting pin and its retaining means may readily be removed when it is time to replace the bit holder.

  • Patent number: 4163346
    Abstract: A tangential grinding machine has a variable grinding feed rate which is dependent upon the length of the cutting or grinding path which occurs between the grinding wheel and a workpiece. The variable feed rate accomodates fluctuations in grinding wheel and workpiece dimensions to control the grinding time and optimize stock removal rates.

  • Patent number: 4160819
    Abstract: A method of inhibiting or reducing the irritation of skin resulting from allergic contact dermatitis, caused by contact with natural or synthetic allergenic agents, e.g. poison ivy, and dinitrochlorobenzene, respectively, is described. The method comprises applying to the skin an irritating reducing effective amount of a protective agent which is an organic compound having at least two polar groups, e.g. carboxyl groups, separated by a chain of at least 15 atoms the majority of which are carbon atoms and optionally containing a cyclic moiety of at least 5 atoms, prior to contact of the skin with the allergenic agent. The protective agent may be combined in a pharmacologically acceptable base for application to the skin.

  • Patent number: 4140238
    Abstract: A nozzle shut-off valve for injection molding machine for plastic material, especially thermoplastic material, has two pneumatic cylinder-and-plunger units. One such unit has its plunger mounted to reciprocate so as to block the passageway of the plastics through the nozzle. The first such plunger and cylinder unit is provided with a pilot passage in the valve nozzle so that the pressure of molten plastic can be used to open it. The second such unit is much smaller diameter and has its plunger mounted to block the pilot passage so that the second unit in effect becomes a pilot valve and controls the application of fluid pressure through the pilot passage to the first unit plunger or blocking plunger.

  • Patent number: 4134486
    Abstract: A workpiece detection circuit in an article handling apparatus aborts workpieces from the apparatus whenever an unanticipated workpiece presence or absence is sensed. An error signal from either of a pair of parallel gating circuits removes a primary chute from the workpiece flow path and directs workpieces down a secondary or abort chute.

  • Patent number: 4133625
    Abstract: A machine for automatically forging and thermoforming of hollow thermoplastic biaxially oriented articles has a carrier assembly to carry, lock and unlock forging dies, indexing means to move the carrier assembly and dies past a series of work stations, and an article unloading means. Three work stations are in the automatic machine: forging where the die parts are locked together and the workpiece is forged into engagement with the die; thermoforming to which the die with the workpiece (now called a preform) gripped therein is moved into register with thermoforming mold means; and article ejecting means which include mechanical means for unlocking the die and removing the hollow article therefrom. The carrier assembly is so supported that the strains of forging and thermoforming are taken up by frame tie rods rather than the die mounting means.

  • Patent number: 4123642
    Abstract: Apparatus for obtaining full tooth width induction hardening of gear teeth. The method comprises attaching gear teeth shaped non-magnetic material templates to the opposite sides of the gears in close proximity to but spaced from the sides of the gear teeth. The gear teeth are then progressively induction hardened by passing a current intensifier between the aligned teeth of the templates and the gears while maintaining current flow to the intensifier for the full width of travel of the intensifier between the gear teeth. In the preferred embodiment the faces and roots of the templates are slightly undersize relative to the faces and roots of the gear teeth and the tops of the teeth of the template are slightly oversize and extend beyond the tips of the teeth of the gear.

  • Patent number: 4121142
    Abstract: The present invention is a DC motor drive circuit in which each end of a center tapped supply transformer is connected through a pair of back-to-back thyristors to corresponding ends of a center tapped choke coil. The motor armature is connected between the two center taps. After each zero crossing of an AC input signal, a ramp signal is generated. The ramp is comprised of two linear segments of different slopes to improve the linearity of the output of the thyristors as the conduction angle approaches the zero crossing point. Comparator circuits are responsive to the ramp signal and a command signal for generating trigger pulses to the thyristors. The comparators are biased so that with no command signal present, the comparators operate the thyristors to produce a small alternating loop current through the transformer and the choke with each half cycle of the AC input signal. This maintains conduction through all the thyristors without dithering the motor armature.

  • Patent number: RE30016
    Abstract: A method and apparatus are disclosed for modifying command signals representing predetermined positions of a machine element relative a workpiece as a function of measurable unprogrammed changes in the relative position therebetween. The machine element is responsive to a servomechanism circuit which in turn responds to a control device producing the command signals to command motion of the machine element to programmed points relative to the workpiece. The servomechanism circuit produces interrupt signals for transferring the command signals thereto. A measuring circuit is responsive to the unprogrammed change in relative position between the machine element and the workpiece and is operative to produce feedback signals representing the direction and magnitude of the change in relative position. A first circuit is responsive to the measuring circuit for producing a first signal representing a current unprogrammed change in relative position with reference to a predetermined point.
