Abstract: Apparatus for stemming or peeling produce such as cherries and tomatoes comprising a plurality of roll beds with adjacent rolls thereon being power rotated in opposite directions. The beds are positioned with the rolls in a horizontal plane such that the produce articles will proceed from one bed to the next in an upstream to downstream direction. The downstream beds are positioned slightly below those upstream thereof and the beds are oscillated back and forth in the direction of article travel so that the produce tumbles from one bed to the next to bring all surfaces thereof into contact with the rotating rollers.

Abstract: Apparatus for detecting and separating out articles having pits therein after the product has been passed through a pit removing device. The apparatus includes a pair of detector wheels supported to rotate in the same plane. Each of these wheels is power driven. The adjacent peripheries are spaced apart to receive the articles such that the articles having a greater thickness due to the presence of pits are indicated by the separating force on the wheels.

Abstract: A tool for use with a hydraulic press for holding a connecting rod to enable the removal and reinsertion of the connecting rod bolts by actuation of the press.

Abstract: An apparatus for removal of the epidermis from fruits and vegetables by an abrasive process. The apparatus includes a drum having rotating abrasive coated rolls positioned about the periphery. Rotation of the drum and rollers causes the product passing through to contact the abrasive-surfaced rolls for removal of the peel. To preserve the removed peel material and to conserve water, the peeling process is done in a dry environment during the initial stages with water only being introduced at the exit end of the apparatus to wash from the product any remaining peel particles.

Abstract: A detachable structure for mounting a cover over the bed of a pickup truck, for quick attachment without bolting. A pair of mounting brackets are provided, each including surfaces which interlock with the pickup bed side walls when placed thereon. These mounting brackets releasably engage the cover in a manner to allow pivotal movement thereof. Coil springs extend between the cover and the mounting brackets to retain the brackets on the bed side walls and hold the cover in the open or closed position.

Abstract: A system for detecting data from and recording data on a recording media whereby a single clocking signal generator is utilized for generating the clocking signal both during the recording of data on and the reading of data from the recording media.

Abstract: A light shield for use with video display units, such as video monitors, television monitors, oscilloscopes or the like to block out ambient light. The light shield is made of a sleeve or hood having one end adapted to fit over video display units and a second end fitting over the face such that the user can view the display unit through the sleeve and limit the outside ambient light reaching the display unit.

Abstract: A phase lock oscillator system employing a phase and frequency detector which receives the data pulses and the clocking signal modulated to include only the clocking pulses corresponding in timed sequence to the actual data pulses for generating an error signal to regulate the voltage controlled oscillator.

Abstract: A brake device which can be mounted on such vehicles as a bicycle and includes a brake disc which is fixed for rotation with the hub between a backing plate and pressure plate stationarily mounted. An actuator is provided for moving the pressure plate toward the backing member to squeeze the brake disc therebetween and impart a braking action on the disc and hub.

Abstract: A portable sensor adapted to be moved along a wall to indicate a change in the dielectric constant of the wall thereby to signal the presence of a wall stud within the wall. The sensor incorporates a capacitor plate positioned adjacent the surface in contact with the wall and a circuit for detecting any change in the capacitive charge on the capacitor. Any change in capacitive charge as the sensor is moved along the wall is due to a change in the dielectric constant of the wall because of the presence of a wall stud behind the wallboard. The sensor visually indicates any change in the dielectric constant in a manner to permit selection of the center of the change in dielectric constant thereby indicating the center of the wall stud. An additional feature of the circuit permits automatic calibration of the sensor to a level corresponding to the dielectric constant of the wallboard so that any change in the dielectric constant of the wall due to the presence of a stud is readily observable.

Abstract: A center unwinding reel assembly including first and second reel members which are combined to form a takeup assembly on which the film or tape can be wound. After the film is wound these members are separated with the wound film remaining on the first member, and a third member is fixed to the first member to form a payout assembly enabling the unwinding of the film from the center thereby doing away with the need to rewind the film after each use. In addition provision is made for partially rewinding the film on the payout assembly so the film can be run backwards.

Abstract: A servo system incorporating an attenuator for reducing the error signal an amount proportional to the magnitude of the error signal so as to minimize overshoot without affecting the stability in the system.

Abstract: Blanching apparatus comprising a sealed compartment having steam manifold spaced throughout and a conveyor system therein for transporting produce such as vegetables from one end to the other for exposure to the steam. Sealed portals permit the entry and withdrawal of the produce while allowing the produce to be treated at a pressure above atmospheric with little escape of steam from the sealed chamber. Pressure relief means are provided in the wall of the container to protect the compartment seals in the event of rapid decompression sometimes resulting from the condensation of the steam.

Abstract: An improved demodulator principally for receiving dibits from a servo track and generating a position error signal responsive to the servo head position relative to the track as indicated by the dibit signal. The invention improves the functioning of the demodulator for movement of the servo head at both high and low speeds and when noise is encountered in the dibit signal.

Abstract: An improved demodulator principally for receiving dibits from a servo track and generating a position error signal responsive to the servo head position relative to the track as indicated by the dibit signal. The invention improves the capability of the demodulator to operate when noise is encountered in the dibit signal.

Abstract: A massage appliance which can be fitted on the hand so that a pliable fluid-filled bag is held in place for contacting the body.

Abstract: An athletic shoe particularly adapted to support the foot while the wearer is running, and having a particular cleat configuration on the sole for contacting the ground or running surface in a manner to both cushion the foot and leg of the wearer and provide improved traction as the heel strikes the surface.

Abstract: A picture hanging bracket comprising a pair of complementary parts, one for attachment to the picture and the other for attachment to the wall, which parts interact to hold the picture and also to permit leveling after the picture is hung on the wall.

Abstract: In a magnetic disc recorder utilizing a servo head to generate a feedback signal for the positioning of the heads on the recording disc, a method for aligning the read/write heads with the servo heads by eliminating substantially all of the effects of head movement occurring during the head alignment procedure.
