Abstract: ABSTRACT     PILOT OPERATED SUPPLY AND WASTE CONTROL VALVE      A four-way control valve comprises two side by side chambers 130, 132.  Each chamber has high and low pressure inlet ports 151, 156, 157, 159 and an outlet port 162, 164.  The high and low inlet ports of each chamber are alternately closed by respective flexible vanes 126, 128.  The vanes extend through and pivot on walls 135, 137 of the chambers and the opposite ends of the vanes are joined by a linking bar 124.  The linking bar is driven by a common actuator such as a solenoid 120.  The pressures applied to the inlet ports of the chambers are inverted such that the pressures at the two outlet ports are opposite high and low pressures.  The four-way valve may serve as a pilot valve 22 to actuate a higher flow capacity three or four-way diaphragm valve.

Abstract: Abstract:   The present invention relates to a cursor control system for use with a computer having a CRT display.  The system includes a hand mounted signal generator for generating an X axis cursor position signal and a Y axis cursor position signal.  The generator includes an X axis array of light transmitting elements, an X axis array of light receiving elements, a Y axis array of light trans-mitting elements and a Y axis array of light receiving elements.  A space is provided for separating the X axis array of light transmitting elements from the X axis array of light receiving elements and for separating the Y axis array of light transmitting elements from the Y axis array of light receiving elements.  An interrupting unit is provided which is controlled by a finger of the hand partially located within the space for interrupting light energy from reaching individual light receiving elements in the X axis and Y axis array of light receiving elements, the light energy having been transmitted from associated individual light transmitting elements in the X axis and Y axis array of light transmitting elements.  A scanner is provided for sequentially scanning the X axis and Y axis array of light transmitting elements and the X axis and Y axis array of light receiving elements to thereby produce the X axis cursor position signal and the Y axis cursor position signal.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention refers to an assembly for the attachment of overhead lines, specially power lines to an insulator, having a loop formed of at least two twisted wires, which are bent at approximately the midline in a bend region, forming two legs so as to lodge said cables between the twisted legs thus formed, the bend region being smooth and untwisted. The object of the invention lies in providing an assembly that dispenses with the utilization of a connection element convent-ionally employed in the installation of overhead networks. Such object is attained by the invention due to the fact that the wires of said loop can be separated in two groups in the bend region, a pin having at least one retention element being provided, said pin cooperating with an insulator and insertable in the loop.

Abstract: ABSTRACT           A digital-to-analog converter which develops an analog output representative of the difference be-tween two digital inputs represented by the rates of two series of pulses.  A prescribed number of pulses of each series is counted to develop two oppositely directed counter pulses, each having a duration dependent upon the time required to count the prescribed number of pulses. The counter pulses are integrated and the integration signal is sampled at the mid-point of each rise and decay. The average of the samples of each rise and decay repre-sents the difference between the rates of the two series of input pulses.

Abstract: Abstract of the Disclosure An improved support system for a person in a sitting attitude to vary pressures produced on affected body areas adequate to improve blood perfusion thereat.  A first, primary resilient support element is provided that defines a generally centrally located opening with a second, inflatable fluid support element received therein.  The inflatable support element is located to receive the ischial tuberosities thereover and is normally deflated whereby minimal pressures are generated on body areas thereover.  Fluid may be supplied to the second support element to inflate same, thereby supporting a greater proportion of the body weight and lowering pressures generated on the portions contacting the first support element.  A valve controllably inflates and deflates the second element.  A timer may be employed to activate an air compressor to inflate the second support element after a predetermined interval. Cyclic pressure changes permit all affected body areas to enjoy good blood perfusion periodically, enhancing comfort and lessening the likelihood of development of ulcers for a person sitting on the support system. The system may be incorporated into a wheelchair.

Abstract: ABSTRACT OF THE DISCLOSURE         A blade assembly is adapted to be connected to the conventional three-point hitch of a farm tractor.  A generally horizontal boom pivotally carries at its rear end a blade bucket which is swigable by means of a pair of double-action hydraulic jacks pivoted to the blade and to the boom.  The front end of the boom is adapted to be pivotally connected to the pair of laterally-spaced hitch lever arms of the tractor hitch system.  A spacer frame upstands from  and is pivotally connected to the front ends of the boom.  A central lever arm is pivot-ally connected intermediate its ends to the upper portion of the spacer frame.  A central link pivotally interconnects the front end of said central lever arm with the front portion of the boom.  A double-acting hydraulic jack interconnects the boom with the pivotal connection between the central lever arm and the link.  The link, the boom, the spacer frame and the portion of the central lever arm which is rearward of the spacer frame form the sides of deform-able quadrilateral structure which cause raising and lower-ing of the boom by extension and retraction of the last-named hydraulic jack respectively.  The blade itself is characterized by a main panel bent to form three flat plate sections at an angle one with respect to the other.         The blade can enter the ground and shovel back the earth with the minimum power requirement.

Abstract: ABSTRACT OF THE DISCLOSURE             A suspension system for a vehicle having a shock absorber strut with a reciprocal piston rod located within a cylinder, and attachments for securing the piston rod and cylinder to spaced parts of the vehicle. An air spring includes a rigid annular canister mounted on the piston rod by a resilient rotatable mount.  The canister forms a fluid pressure chamber in conjunction with a flexible diaphragm, one end of which is sealingly connected to the cylinder by an annular rigid sleeve which forms an air spring piston.   The flexible diaphragm has inner and outer radially spaced portions connected by a rolling portion.  A rigid member resembling a cutaway can is mounted on the rigid canister portion of the air spring and extends about a predetermined portion of the outer portion of the flexible diaphragm and restrains outward expansion of said portion.   Restriction of the outward expansion of only a portion of the flexible diaphragm exerts a lateral force on the strut to counteract the unbalanced lateral forces acting thereon due to the offcenter mounting of the strut with respect to the point of contact of the vehicle wheel with the pavement.
