Abstract: An electrohydraulic servo system is compensated by an electrical control system and has a position related feedback loop and a servovalve with a differential pressure transducer connected as a feedback loop between the output and return lines that extend to a hydraulic motor or other driven means from said servovalve.

Abstract: A coupling includes a pair of cup-shaped members with one mounted for sliding axial motion inside the other. The outside coupling acts as a support or base which is connected to a conveyor that moves the coupling between workpiece loading and unloading means. The inside member also carries detents which move radially in and out to grasp or release the workpiece in response to axial motion between the two cup-shaped members. When combined with a conveyor, appropriate cam and follower means are provided to cause the coupling to be operated for grasping and releasing the workpiece in a timed sequence and to move the coupling from a workpiece loading station to an unloading station. The coupling and conveyor are suited for use in handling soft or easily marked materials such as plastic, soft metals, and the like. A method for workpiece handling includes steps of rotating, advancing in stop-and-go fashion while continuously rotating, and unloading.

Abstract: An improved pusher-type chain for a conveyor, the conveyor being of the type comprising an elongated base means having a bottom and upstanding side guides or flanges. The base means may be made up of two or more longitudinal sections joined together in such a way as to permit them to be shifted with respect to each other from side-to-side about the juncture therebetween and to be shifted vertically upwardly and downwardly with respect to each other about the same or other juncture. The pusher-type chain is a continuous chain adapted to be driven in such a way that one of its spans moves longitudinally along the upper surface of the base means bottom and between the upstanding side guides or flanges in a conveying direction whereby to advance the material being conveyed along the upper surface of the base means bottom. The chain itself comprises a plurality of rigid pusher elements of improved construction normally extending substantially transversely of the conveying direction.

Abstract: This disclosure is of an automatic tool changer on a machine tool which is arranged to produce movement of a tool operator about a rotary axis when the tool is used. The exchange of tools to and from the machine can be automatically accomplished without regard to the position of the tool operator in its normal range of positions. The tool operator does not return to a predetermined angular position for the tool change, but only stops for so long as the execution of that tool change.

Abstract: A digital circuit useful in a numerical control system for determining during a preliminary execution of a program the axial components of a tool offset compensation. During a preliminary operation of the program, the sum of the squares of the axial components of displacement of the tool are compared to the square of the desired tool offset. When the sum of the squares equals or exceeds the square of the offset, the current values of the axial components of displacement are stored and used as the axial offset components during a subsequent execution of the program.

Abstract: The degree of skin irritation of detergent compositions is reduced by adding small amounts of compounds having at least two polar groups, e.g. hydroxyl, carboxyl, ester, amino, and amido groups separated by an organic radical of at least 15 carbon atoms which contains a cyclic group. In particular, various aliphatic, aromatic and heterocyclic amino, amido and ester derivatives of polymerized fatty acids are disclosed.

Abstract: A toolhead having a spindle mounted in axially spaced bearings wherein one of the bearings is allowed to slide axially during dynamic effects on the bearings or thermal expansion and contraction of the spindle, the axial movement being made possible by the provision of rows of barrel-shaped rollers.

Abstract: A turning machine with a rotary work spindle and a slide having a lower carriage movable in parallelism with the axis of the spindle, an upper carriage movable on the lower carriage at right angles to the spindle axis, and a tool support on the upper carriage. The tool support is comprised of two indexable turrets, each having a plurality of tools therein, and a common indexing means so that the turrets are indexed simultaneously.

Abstract: A needle endoscope includes a hollow needle of about 18-gauge, a lens system within the needle, an image transmitting bundle of flexible fiber-optic rods within the needle, a plurality of illumination transmitting fiber-optic rods within the needle, an operative channel within the needle, and apparatus to shift the image transmitting bundle with respect to the lens system and needle to provide focus adjustment for focusing the endoscope on objects at various distances from the end of the needle. The channel is adapted to receive an electrode having an end which, when extended beyond the needle, can be microscopically viewed and supervised through the needle during application of radiofrequency pulses to the spinal cord's nerve tracts or nerve cells, for example. Both medical and industrial uses are contemplated.

Abstract: The invention involves pulling the hide mechanically from beef carcasses, in a manner such as to avoid hide and carcass damage without resorting to electric stimulus, and without the need for trimming knife labor in removing the hide effectively and advantageously from the skull of the carcass.

Abstract: Urea is made from ammonia and carbon dioxide by first reacting ammonia and carbon dioxide to form urea, ammonium carbamate and water, and then decomposing the carbamate to ammonia and carbon dioxide which are returned to the reaction zone.
