Title: Conductive polymer ptc circuit protection devices
IPC: H01C7/02
Filed: 1981-04-21
Granted: 1984-04-26
Abstract: Circuit protection devices which comprise two columnar electrodes and a conductive polymer element, at least a part of which is a PTC element. The device is so constructed that if a hot zone forms in the PTC element when current is passed through the device, it forms at a location away from the electrodes, thus increasing the useful life of the device. In one preferred embodiment, the conductive polymer element has an intermediate portion of increased resistance, thus causing the hot zone to be located at or near the intermediate portion. The intermediate portion may be of reduced size and/or be composed of conductive polymer of relatively high resistivity.

Title: Apparatus for initiating explosions and method therefor
Inventor: SAUNDERS PETER JOHN
IPC: F42D1/04
Filed: 1983-05-16
Granted: 1985-04-11
Abstract: Detonating apparatus comprises a plurality of multi- channel exploders (MCEs) connected to a control unit which provides an operator/apparatus interface remote from the MCE's detonator circuits. MCEs measure integrity, resonant frequency and impedance at resonance of the detonator circuits connected to each channel, and are thereby programmed to give optimum firing current at the resonant frequency. The control unit provides electrical power, interrogates the MCEs on the status of their detonator circuits, and gives firing signals to be obeyed by MCEs after predetermined delays.

Title: Radio communication system
Inventor: FUJII YUICHI
IPC: H04B7/26
Filed: 1990-02-13
Granted: 1993-04-14
Abstract: In a radio communication system, a base station transmits a signal including a component which designates a power level. A mobile station receives the signal from the base station. In the mobile station, an output power of the mobile station is set to the designated power level, and a field level of the received signal transmitted from the base station is detected. A determination is made as to whether or not the detected field level of the received signal is equal to or higher than a predetermined field level. The output power of the mobile station is decreased from the designated power level by a predetermined value when the detected field level of the received signal is equal to or higher than the predetermined field level.

Patent HU-216491-B (HU)
Title: Filter equipment
Inventor: KUPKA MARTIN
IPC: B01D33/00
Filed: 1993-05-12
Abstract: A filtering device is disclosed having tubular filtering elements (8) made of perforated tubes (54) on the outer side of which are arranged filtering media (55). The liquid to be filtered flows against the filtering bodies (8) transversely to the axis of the tubes. Preferably, the filtering bodies (8) are arranged in a circular ring, are mutually linked into a cage and form a rotor (5) which rotates in a container (1) for the liquid to be filtered. Several such cages may be concentrically arranged inside each other, and adjacent cages turn in opposite directions. Pulsating currents are thus generated in the liquid to be filtered which prevent the filtering media (55) from being prematurely clogged by sediments.

Granted: 1987-10-28
Abstract: A single resource in the form of a data bus (BS) is shared among a number of users in the form of Modules (M). Control of the bus is restricted to not more than one module at a time. Each module is assigned a different n-digit binary identity number, all the identity numbers containing the same number m of ones, and associated with BS there are n lines AB which perform the wired-OR function. When a request for the control of BS is made, the module or modules determines whether the resulting number carried by AB contains exactly m, or more than m, ones. If it contains more than m ones, indicating two or more requestors, arbitration between them takes place in a known manner to determine which of them shall control BS first. But if the number on AB contains exactly m ones there can be only one requestor and so arbitration is disposed-with.

Title: Battery charging control circuit - incorporating a timer and a voltage sensitive switch to permit further trickle charge
IPC: H02J/
Filed: 1974-09-23
Granted: 1979-04-10
Abstract: The circuit is intended for maintaining the charge on the battery after the main charging period is completed. To prevent overcharging, the charger circuit is under the control of a voltage sensor which checks the open circuit battery voltage against a reference, and gives an output to an AND gate if the voltage falls below the reference. The second AND gate input comes from an interval timer. The presence of both signals closes the circuit to the charger. A timing element may be included which then keeps the charger in operation for a predetermined span which is typically two minutes.
