Abstract: Apparatus for electronically measuring the size of a foot for determining a properly fitted specific shoe size. A light source is arranged to cause an outline of a foot to be delineated upon a translucent panel. Light energy is directed from the panel through photo optic means to an electronic device containing means for inherently discriminating impulses of energy into a distinct white/black status to produce an electronic duplicate of the foot outline. The electronic image of the foot is processed within the apparatus to determine an accurately fitted size of shoe for the measured foot. Video display means is provided so that a customer may view the process of measurement of the shoe size and be informed of the precisely determined size of shoe to fit the customer's measured foot. Specific hardware is provided in the form of schematic diagrams for defining the operation of the invention.

Abstract: This invention deals with a machine or method for transferring decalcomania (decals) from a rolled carrier web or strip to a series of articles. The machine supports a supply reel containing the web and transports the web from the supply reel through a photo sensitive indexing assembly, past a decal applying pressure roller assembly, to a take-up tensioning roller powered by a motor for driving the web. The photoelectric or other appropriate device actuates the release of a brake or other holding means from a web clamping position so that a decal on the web is placed in position for transfer to an article. The web tensioning mechanism is provided to hold the web under tension during application of a decal. A photo cell assembly may be operated to adjust the position of the web so that successive decals are precisely at the transfer position.

Abstract: A magnetic clutch for selectively connecting a rotatable input shaft to a rotatable output hub using magnetic flux. An output disc connected to the output hub is mounted between a pair of input discs connected to the input shaft. Magnetic flux passing through the output disc and the input disc clamps the output discs between the input discs. The magnetic flux linking the input and output discs provide additional torque to cause the output disc to rotate along with the input disc, so a relatively small clutch can provide a large output torque.

Abstract: A control circuit for connecting and disconnecting an electronic motor brake with an AC motor and a source of AC power over electromechanical relay contacts wherein opto-coupled circuits operatively control energization and de-energization of a braking circuit with minimal time delay and provide operational response of the relay contacts in a substantially sparkless manner to promote contact life.

Abstract: A tractor scraper hitch steering and suspension system wherein a tractor drive wheel axle frame is pivotally connected to a tractor main frame to permit vertical movement of the tractor drive wheels relative to the tractor. Two hydraulic cylinders are pivotally connected between the tractor drive wheel axle frame and a cross arm forming a part of a hitch assembly that secures the tractor to the scraper. The hydraulic cylinders dampen vertical bounce movement that occurs during operation and control tilting or rolling motion between the tractor portion and the scraper portion that occur about their common longitudinally extending axis. A locking brake is provided to resist vertical motion of the tractor drive wheel axle frame to stabilize the depth of a cutting edge of the scraper during operation and obtain a steady depth of cut.

There is provided a pressure regulating device interposed in the connection between the speed control device and the hydraulically operated control for the pumps of the two hydrostatic transmissions, which is arranged to increase and reduce the pressure supplied to the hydraulically operated control of one of the pumps so as to maintain the speeds of the two tracks equal. Preferably, the system further includes a sensor arranged to detect differences in speed of the two vehicle tracks and an actuator arranged to control the pressure regulating device in dependence on the signal received from the sensor.

Abstract: A remote controlled hydraulic circuit of the type comprising a source of pressurized fluid, a number of hydraulic motors connectible to the source of pressurized fluid, and control means for connecting the source of pressurized fluid to the hydraulic motors, the control means being remotely piloted by a series of pressure signals each of which corresponds to the opening of the connection between the source of pressurized fluid and a respective hydraulic motor. The hydraulic circuit according to the invention includes selector means for establishing priority for supplying pressurized fluid to one or more preferential hydraulic motors. These selector means are intended to detect, when operatively active, pressure signals corresponding to the supply of pressurized fluid to the preferential hydraulic motors and, in this condition, to render inoperative the control means associated with the other hydraulic motors, should they already have been activated to effect the supply of these other hydraulic motors.

Abstract: A link set capable of connection in series to form an endless silent chain has a pair of guide links held apart by, and non-rotatively fastened to the ends of a pair of pins. A central link pack devoid of bushings to maximize the amount of material available to resist the stresses encountered under load is connected between and directly engages the pins. A pair of articulating link packs are rotatively connected to one of the pins on either side of the central link pack. Bushings are provided in the articulating packs to improve the wear life of the chain.

Specifically, the invention is characterized by an inverted U-shaped hanger detachably and snugly mounted upon the head bar in a stable position, wherein one leg of the hanger serves the dual function of suspending a hygienic reservoir assembly in a partially stabilized position by limiting the swinging movement of the lower free end portion of the assembly backwardly in the direction of the other hanger leg.

Abstract: The motor braking circuit for use with an alternating current motor and an AC power source includes a power circuit for supplying a DC braking current to the AC motor and a motor speed sensor which causes a mechanical brake to engage the AC motor and its load when the motor speed decreases to a predetermined value. The DC braking current is applied to start the electrical braking cycle as soon as the AC source is disconnected from the AC motor. The RPM sensor monitors the speed of the AC motor during the electronic braking cycle and causes the mechanical brake to engage the motor and its load when the motor speed decreases to a predetermined value to complete the stopping sequence. The AC motor braking system can be installed without any additional direct wiring or additional hardware to the AC motor.

Also, a form of the invention involves an arrangement wherein the wire side links of both the inner and outer units are welded to pins and the pins roll on each other to provide the necessary pivoting action of the chain.

Abstract: A safety or lock pin operatively engaged in a portion of the vehicle adjacent to the vehicle lift arm and coupled to the vehicle frame. The safety or lock pin is inserted into the portion associated with the vehicle frame so that the lift arm is prevented from lowering past the safety pin. A retaining pin is engageable in a bracket positioned adjacent the opening for the safety pin to retain the safety pin in its operative position. When in an inoperative position the safety pin is carried in a bracket secured to the vehicle frame and having an aperture through which the retainer pin passes to insure that the safety pin does not become lost during vehicle operation. Suitable safety chains couple the retaining pin to the safety pin, and the safety pin to the vehicle frame to insure that neither pin becomes separated or lost.
