The invention is advantageously utilized for the production of layer capacitors.

Abstract: An apparatus such as a farm implement or other mechanical device subject to varying loads and power requirements has an hydraulic circuit which automatically shifts two or more hydraulic motors from a normal series operation at high speed to a parallel operation at reduced speed but higher torque in response to increased fluid pressure upstream of the motors. In a disclosed embodiment, a valve is connected to block flows from the fluid source to inlet of one motor and from outlets of both motors directly to drain under low pressure conditions but to shift to allow two parallel flows to the two motors upon increase in pressure in the flow from the source. A third motor driving an auxiliary device such as a material feed is by-passed in the parallel-flow condition.

Abstract: A simplified and less expensive method for producing layer capacitors is disclosed in which an output capacitor is produced by winding several master or parent capacitors on a drum one upon the other. The parent capacitors are separated from one another by separating films of synthetic material. These separating films are then cemented to one another and to one of the parent capacitors lying underneath, but not to the parent capacitor lying above. Protruding portions of the separating layers are ground off. The portions of the separating layers remaining serve as protecting covering layers after the separation of the parent capacitors from one another.

Abstract: An agitator for a vertical-axis automatic clothes washing machine has a plurality of vanes extending upwardly from a skirt thereof. A corresponding plurality of crescent-shaped, lobe-like cams projects outwardly and upwardly from a periphery of the skirt between the pairs of agitator vanes. Each cam extends approximately 33.degree. upwardly from the horizontal and is geometrically defined by two edges forming a segment of the surface of a cone coaxial with the agitator. The inner edge of each cam has the radius of the circular perimeter of the agitator skirt with which the edge is colinear; the upper edge has a somewhat smaller radius. Lower vertical flat vane portions extend radially and upon impelling laundry liquid produce a low pressure pocket behind each vane.

Abstract: A flexible joint for use in suspension systems and the like has a rigid cylindrical member, a resilient bushing encompassing the inner member, a split casing having opposed semi-cylindrical surfaces holding the bushing under compression toward the inner member and secured together in bushing-compressing relation, and rigid extrusion barriers preventing compression induced extrusion of the bushing into partings between the casing parts. Configuration of the extrusion barriers complements the compression loading of the resilient bushing by the surfaces of the casing parts.

Abstract: An inexpensive, lightweight, hybrid transmission is provided in which a high speed rotating-input sun member drives at least two rows of rollers including a first row of intermediate circumferentially positioned rollers by way of a pure friction drive contact. The first intermediate row similarly drives a second row of circumferentially mounted rollers via a pure friction drive contact. The second or subsequent row rollers are mounted on fixed axes by straddle bearings and the individual support shafts thereof are provided with small diameter output gears with positive teeth for cooperation with a toothed output ring or output bull gear. The system provides quiet and efficient force transfer through the friction drive surfaces and, at the same time, provides high torque transmission through the relatively slowly rotating positive drive gears.

Abstract: A keyboard assembly incorporates a plurality of key members molded of thermoplastic material, each of the keys having an integrally formed pivot wall supported on a pair of pivot points disposed on a pair of pivot members integral with a pivot bracket. The key members are located laterally by the pivot wall being gripped between the pivot points, and is located longitudinally relative to the pivot members by means of two pairs of locating ridges, one pair on each side of the pivot wall. A pair of resilient tabs integral with the plastic key member engage the upper corners of the pivot members, and a rib extending downwardly from the pivot wall extends into a slot to resist twisting of the key member. A key guide strip for the key member has a pair of vertically aligned projections, for supporting bumpers which guide the forward end of the key member and which provide a cushioning action for noiselessly stopping of upward movement of the key member.

Abstract: In an illustrated embodiment, a selective receiver receives a first echo impulse produced at the interface between the precursor water path and the subject under examination, as a measure of the precursor transit time (T.sub.v). Thereafter, each transmit pulse is synchronized with the receipt of such echo impulse so that multiple echoes resulting from such echo impulse coincide in time with desired echo signals, and thus do not disturb the accuracy of the display. By way of example, a trigger stage may respond to the interface echo to directly trigger transmission of the next ultrasonic pulse. The trigger stage may also actuate a first monostable with a time interval corresponding to the nominal precursor transit time (T.sub.v), a second monostable being triggered by the first monostable to establish the actual gating interval for receipt of the resultant interface echo signal.

Abstract: In the illustrated embodiment sets of four diaphragm plates are utilized to define the margins of a beam path configuration having the shape of a four-sided pyramid with its vertex coinciding with the focus of the x-ray tube. Each set of four diaphragm plates is mounted by means of levers which are capable of being pivoted in a scissors-like fashion so as to adjust the angle of divergence of the x-ray beam with respect to a given plane. For actuating the levers, a motor driven cam is coupled with the levers via a roller and a pair of links, a tension spring urging the levers in a direction so as to press the roller into following relation to the cam surface.

Abstract: A method for continuously refining impurities from a copper melt wherein molten copper is conveyed sequentially through reduction and oxidation zones where it is reacted with gases to free it from impurities. The method involves passing an oxygen containing gas into contact with a molten copper bath in the form of a vertical jet under controlled pressure conditions, controlled velocity, controlled spacing and the like, resulting in a convective material exchange between the copper bath and the gas before the gas is used to oxidize a reducing gas stream.

Abstract: An automatic washing machine of the vertical axis, oscillating agitator type promotes an improved rollover washing action. A separate lower camming element beneath the skirt portion of the upper, oscillating agitator is moved in a stepwise, unidirectional rotation about the axis and carries on an outer periphery thereof at least one ramp surface inclined upwardly opposite its direction of rotation. A clutch arrangement between the agitator skirt and the camming element effects positive rotation of the element during a portion of each one-half cycle of agitator oscillation, leaving the element at rest during the other part of the oscillation cycle. In one embodiment a ratchet-type clutch is employed having inclined teeth on the agitator skirt and spaced-apart, oppositely-inclined lugs or notches on a cooperating portion of the camming element.
