Abstract: ABSTRACT OF THE DISCLOSURE A novel toilet seat cover is provided herein.  The cover comprises a water-impermeable, non-porous, very light weight, easily disposible paper, preferably waxed, provided with a central longitudinal opening in the form of a slit or precursor thereof in the form of a perforation or a line of weakness. The toilet seat cover is folded longitudinally along the slit perforation and then is folded transversely in a zig-zag or back-and-forth accordion type fold at least for the region of the slit or perforation.  The toilet seat cover, when in use, is adapted to be placed over the toilet seat and to have its peripheral edges folded under the toilet seat to be retained thereby and further, by the sole application of body pressure by the user is thus adapted to be made to fit a toilet seat opening automatically.  The toilet seat cover may be dispersed in the form of individual folded seat covers or in the form of a seat cover detached from a roll of a plurality of identical seat covers. Thus, with the present invention, the entire toilet seat cover is placed on the toilet seat, and the peripheral edges then folded under the toilet seat so that the cover may be retained thereby.  Then, by the user sitting on the toilet seat cover, the slit or perforation automatically extends and expands to provide the optimum opening.

Abstract: Abstract:            A compressor drive system for controlling the gas pressure in a pressure gas volume (106) connected to the compressor (101). A brushless alternating current motor (23) is directly coupled to the compressor, which is driven with the same speed as the motor. The pressure in the gas volume (106) is sensed by pressure sensing means (109) connected to a converter (114). The converter simultaneously changes the amplitude and frequency of the drive voltage supplied to the motor (23). This is done in response to pressure changes in volume (106). The motor is stopped if the pressure exceeds a preset maximum value. A pressure gas container (104) is depressurized at motor stop to allow restarting without counter pressure on the compressor. Means (44) for controlling the amplitude and frequency of the drive voltage is provided so that the normal speed maximum load current is never exceeded during motor start.

Title: Circuitry for allocating access to a demand-shared  bus

Abstract: CIRCUITRY FOR ALLOCATING ACCESS                  TO A DEMAND-SHARED BUS            Abstract Circuitry is disclosed for allocating requests for demand-shared bus access among a plurality of service requesting ports.  During bus contention time, each requesting port synchronously and sequentially applies the digits of its assigned unique priority code to the bus beginning with the most significant digit.  After the application of all digits, only the requesting port having the highest code remains in contention and it seizes the bus.  Increased flexibility in port preference is provided by the use of a plurality of status flip-flops in each port for generating dynamic port parameter bits.  The generated parameter bits are normally applied to the bus as the most significant bits of a dynamic port priority code during contention time.  However, the selective application of a mask signal to a mask conductor during contention time causes each requesting port to prevent any parameter bits from being applied to the bus as long as the mask signal remains.  This returns control of the port preference to any unmasked parameter bits and to the assigned port priority codes.

Abstract: ACTIVE IMPEDANCE LINE FEED CIRCUIT            Abstract of the Disclosure Normal operating range of an active impedance line feed circuit is extended to at least that of a prior art passive resistance line feed circuit.  The active impedance line feed circuit includes tip and ring feed resistors in series with outputs of tip and ring amplifiers for coupling a.c. signals to a two wire communication line with an effective source impedance as defined by an a.c. feedback network in response to differential currents in the communication line.  Effective output direct current incremental resistances of the tip and ring amplifiers are controlled by a d.c. control circuit connected across the tip amplifier.  In an instant of an OFF HOOK communication line of less than a certain resistance a predetermined constant direct current is supplied by controlling the output direct current incremental resistances to be high.  In an instant of the communication line resistance being too high, as in the case of a longer line, the output direct current incremental resistances of the tip and ring amplifiers are controlled to approach a few ohms such that at least a minimum energizing direct current is suppliable from the active impedance line feed circuit over an extended range of communication line.                     - i -
