Abstract: A shield or deflector for a dishwashing machine rack is disclosed. The deflector has a bottom wall and a front wall that permits food particles to be caught or deflected away from the floor when the rack extends beyond the door of the dishwashing machine when the door is in an open position. The deflector is removably or permanently mounted on the rack.

Abstract: A pet flea and tick brush comprising a container with deforming walls. The container includes a threaded hollow container neck in communication with the inside of the container. A hollow brush neck threadably engages the container neck. The hollow brush neck includes an essentially central axis that defines approximately between about 50.degree. and about 70.degree. angle with a horizontal plane. A brush head having a generally oval elliptical shaped face is integrally bound to the brush neck. The oval elliptical shaped face includes a facial plane that makes approximately between about 50.degree. and about 70.degree. angle with the central axis of the hollow neck brush. A plurality of generally frusto-conical hollow teeth with a discharge aperture is integrally bound to the oval elliptical shaped face. The ingredients from within the container pass from the container through the discharge aperture of the hollow teeth when the container is squeezed and/or inverted.

Abstract: An electric bend head for bending tubes includes a frame mounting a gear box housing with a rotatable main shaft extending through the housing. A secondary shaft coaxial of the main shaft is journaled within the housing and projects therefrom. A rotatable worm gear within the housing is coaxially mounted upon the secondary shaft and a worm drive gear is journaled upon the housing and in mesh with the worm gear. A variable speed reversible electric motor upon the frame has a main drive shaft, and a transmission interconnects the drive shaft and the worm drive gear. A secondary drive plate is mounted the secondary shaft and a main drive plate is spaced from the secondary plate and mounted upon the main shaft. A bend die of semicircular shape, having an outwardly opening channel, is axially mounted upon the main plate.

Abstract: In a pulse-width-modulated servo motor control system, a signal indicative of the average terminal voltage of the servo motor is fed back to stabilize the response of the control system. Under normal conditions the feedback signal is representative of the velocity of the servo motor output shaft and thereby operates to stabilize the control system response as a function of the output shaft velocity. Under adverse conditions tending to increase the power supplied to a motor, the feedback signal increases in a manner to limit the power supplied to the motor and to maintain the control system bandwidth substantially constant.

Abstract: In the recovery of hydrocarbon materials from subterranean formations, the simultaneous production or loss of other fluids such as water is inhibited by the selective introduction into the subterranean porous structure of discrete spheroidal microgels of a water-swollen or water-swellable, crosslinked polymer such as crosslinked polyacrylamide.

Abstract: A system and method reduces the access time for a magnetic head transducer to be positioned on a selected recording track of an information storage media. A digital processor, responsive to a signal indicative of the selected track location determines the number of tracks separating the present location of the head from the selected track location and generates a series of alternate acceleration and deceleration control signals in accordance with a permanently stored instruction set. If the head is to be moved fewer than a predetermined number of tracks, the digital processor controls the head positioning servo system to move the head to the desired track location in single track increments.

Abstract: A circuit which utilizes a single transistor and a particular resistor combination to form a new slope reversing circuit in which the output voltage is a function of the input voltage with a change of sign for a monotonically varying input voltage. The circuit is valid for a transistor having a high current gain operating in either the active transistor region or the saturated transistor region. The circuit is of particular value when used as a brightness control circuit for a light display used in conjunction with a digital clock for automobile use.
