Abstract: Abstract of the Disclosure A thermal printing device comprises a continuous bar of electrically resistive material, with patterns of electrical conductors on each side of the bar.  Connections are made to the bar from the conductor patterns at closely spaced position.   The conductor patterns are formed as columns on one side and rows on the other side to enable connections between columns and bar and rows and bar such that the number of external connections is minimized.  The connections to the bar from the conductor patterns are staggered on one side of the bar relative to the other side.  This doubles the centre-to-centre distance of such connections as correspond with connections which are opposite each other.  This enables wider connection paths while still maintaining the original resolution.

Abstract: TIP AUTOMATIC NUMBER IDENTIFICATION CIRCUIT         ABSTRACT OF THE INVENTION A circuit for identifying which one of two parties has initiated a toll call.  Circuitry connected to the subscriber drop of one party, e.g., the tip party of a two-party telephone line, generates a ground mark during the toll ticketing condi-tion when that tip party has initiated a toll call.  Loop cur-rent sensing circuitry senses the loop current flowing in the subscriber drop to the tip party.  Voltage sensing circuitry senses the potential, with respect to ground, on each conductor of the telephone line.  Switching circuitry applies a ground mark to the telephone line when loop current flow to the tip party has been interrupted and negative potential is applied to the tip conductor.  Circuitry is also provided which prevents the application of a ground mark when a ringing voltage is ap-plied to the line.

Abstract: POLYPEHASE SWITCH ARRANGEMENT ABSTRACT: Disclosed is a family of polyphase outdoor interrupter switch arrangements suitable for service in power systems rated up to 34.5 kv with but a single interrupting switch unit per phase. Two insu-lators are mounted on a base member with one insulator supporting a switch blade hinge assembly and the other insulator supporting an electrical jaw contact and interrupting unit. A linkage arrangement mounted to the hinge assembly connects the movable blade to an insulating push rod. The two supporting insulators remain stationary when the switch operates, and only the insulating push rod moves to provide the motive force. The insulating push rod is connected to a lever mounted on a polygon-shaped (preferably hexagonally-shaped) shaft which is mounted for rotation on the base member. A drive lever and connecting linkage is also connected to the shaft. A movable operating rod is connected to a remote switch operator and to the con-necting linkage so that movement of the operating rod rotates the shaft to cause the push rod to pivot the switch to an open position for example. A unique clamping arrangement is provided to permit the various levers to be rigidly affixed to the shaft at any lon-gitudional position without the need for special ma-chining of the shaft. After the switch is open, the insulating push rod and lever form an over-center toggle which prevents the switch blade from being pushed back into the stationary electrical contact as a result of external forces such as wind, etc. An alter-native embodiment of the present invention is designed for triangular configurations of high-voltage distri-bution lines. In this embodiment, a center base member projects upwardly to support one of the switch arrange-ments of the three-phase system. The center base member is formed in two parts which are initially joined together for factory calibration and adjustment, but which can be disassembled during shipment in such a manner that no further adjustment is required when the switch arrangement is reassembled in the field. -2-

Filed: 1977-12-22
Granted: 1981-03-17
Abstract: ABSTRACT OF THE DISCLOSURE A control system for controlling the conduction period of the switch-ing elements of a pulse width control type inverter is provided having a ref-erence pulse generator that determines the output frequency of the inverter output voltage, a constant voltage control circuit for generating an analogue output voltage, an A-D converter for converting the analogue output voltage in-to a digital output signal and a up-counter which counts clock pulses.   The outputs of the up-counter and the A-D converter are compared with each other by a digital comparator.   The up-counter is cleared by the reference pulse when another up-counter counts a predetermined number of output pulses from the comparator.  The up-counter repeats a predetermined number of counting up and clearing operations until it produces a carry signal, and the conduction period of the switching element is determined by an internal between the generation of the reference signal and the generation of the carry signal. In a modified embodiment the up-counter is substituted by a down counter.   The control system has an excellent transient response for external disturbances simplified and rugged construction, and can operate accurately without being affected by the errors of electronic circuit components comprising the control system.

Abstract: ABSTRACT OF THE DISCLOSURE An easily removed or installed cover for swimming pools or the like is provided. It consists in one form of a cover sheet of flexible sheet material capable of assuming an arched configuration over the pool having a periphery in the general shape of the pool. An inflatable air tube in the approximate shape of the perimeter of the pool is dependently attached by an intermediate supporting wall to the underside of the cover sheet perimeter. The exhaust of a low pressure continuously operating blower is connected to the air tube by a flexible link of buoyant tubing. The tubing extends beneath the cover sheet from one side of the cover to exhaust air into the air tube on the opposite perimeter. A second low pressure continuously operated air blower is connected by a second tube to the cover sheet to exhaust air under-neath the cover. An apron attached to the perimeter of the cover sheet and forming an extension of the cover sheet extends over the edge of the pool and includes provisions for securement of the apron and thus the cover to the pool. In another embodiment the tube connecting the air tube to its associated blower enters the air tube on one side of the pool and runs within the air tube around the perimeter of the pool to the opposite side where it exhausts into the air tube. In another embodiment the tube connecting the air tube to its associated blower enters the air tube on one side of the pool and runs within the air tube around the perimeter of the pool to the opposite side where it exhausts into the air tube. In another embodiment, a single blower supplies the air feeder tubing to the air tube and beneath the cover. A multi-chamber valve having a pair of differently sized apertures and associated doors connected to a pivot arm controls and directs the initial air flow to the air tube and subsequently to beneath the cover. In a further embodiment for pools having a separate portion, such as a whirlpool, an auxiliary cover for this separate portion is provided. The auxiliary cover consists of a cover sheet for over the separate portion of the pool and a second sheet beneath it which form an air bag connected to the main cover, which is in a form as described above, by a tube.
