Abstract: ABSTRACT      A pair of running shoes, each having an upper and a sole.  The sole runs the length of the shoe from the heel to the toe and com-prises an outsole and a midsole, the midsole including a first member and a second member, each member being a variable thickness across the width thereof.  The first member is disposed above the second member so that the combined thickness of the members is constant across the width of the sole.  Each of the members is formed of a material having a different durometer, so that the ratio of the thickness of the higher durometer material relative to the lower durometer material is greatest immediately adjacent the inner side of the sole and is lowest immediately adjacent the outer side.  This construction permits greater contact surface area than conventional shoes, thereby distributing impact shock more evenly during running, yet providing medialongitudinal arch support for decreasing abnormal pronation, while allowing for the natural pronation of the foot.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus to generate electricity.  There is a first cylinder having an open end and containing a first piston.  A second cylinder has an open end and contains a second piston.  A pipe communicates the two cylinders at the ends remote from their open ends.  A closure can be moved to close and open the open end of each cylinder in sequence.          The system receives a liquid between that part of the appa-ratus defined by the cylinders and the pipe and between the two pistons.  An electrical generator is operated by move-ment of the liquid in the apparatus to generate electricity when fluid pressure acts on the first piston in the first cylinder, with the second cylinder closed by the closure, it moves the first piston inwardly, moving the liquid to the second piston through the pipe.  Movement of the piston and thus of the liquid acts to operate the electrical generator.          Movement of the closure closes the first cylinder and opens the second cylinder. This allows the fluid pressure to act on the second piston to move the first piston back to its start position. Electricity is also generated by movement of the second piston inwardly.

Title: Signal interference protection circuit for  am stereo receiver
Inventor: ECKLUND LAWRENCE M
IPC: H04H1/00
Filed: 1983-06-07
Granted: 1985-11-05
Abstract: Abstract In the field of AM stereo detection, co-channel or adjacent channel interference may cause some distortion and side-to-side movement of a stereo signal source as well as false "stereo detect" signals in AM stereo receivers having phase locked loop (PLL) systems.  The invention provides a filter receiving the incoming signal and passing only the frequencies resulting from said interference; a sensor measures the output of the filters and if this signal is above a given level, the monophonic mode is enabled, i.e., the pilot detector, the stereo presence indicator and the stereo mode switch are disenabled for a timed interval.  A higher given level of interference is required for stereo disenablement when stereo transmission with pilot tone is already being received.

Abstract: A METHOD OF, AND A TERMINAL FOR, TRANSMITTING BYTES TO A BUS            Abstract of the Disclosure A plurality of terminals, such as digital telephones, are connected to a serial data bus formed by a balanced two-wire line.  Each terminal transmits bytes bit-serially with the magnitude bits first, in order of decreasing significance, then the sign bit, and finally an even parity bit to maintain the balance of the line, the "1" bits being transmitted with alternating polarity.  The terminals operate simultaneously and in synchronism.  If a terminal, during a "0" bit of a byte which it is transmitting, detects a "1" pulse on the bus from another terminal, then it gives up transmission for the remainder of that byte and receives the greater magnitude byte which prevails on the bus.  Thus a single two-wire line can be used for digital transmission in both directions between arbitrary numbers of telephones.                    -i-
