Patent GB-2252881-A (GB)
Title: A low frequency equaliser circuit
Inventor: STRIDE TREVOR
IPC: H03G5/04
Filed: 1991-02-14
Abstract: An equaliser circuit for the low frequency region, for example 20 Hz to 400 Hz, of the audio spectrum is provided with an ideal low frequency response (Figure 5). Thus, when the circuit is giving gain, a bandpass response is provided, whereas whilst the circuit is attenuating, a lowpass response is provided. One circuit providing this response has an input resistor (Rin) in series with an output resistor (Rout) which provides a feedback path to the inverting input of an operational amplifier (A). The non-inverting input of the amplifier (A) is connected by way of a lowpass filter (FL) to the centre tap of a potentiometer (P) whose high impedance terminal is connected to the circuit input, and whose low impedance terminal is connected by way of a highpass filter (FH) to the output of the operational amplifier (A). The potentiometer (P) can be used to control the circuit such that its response is set by the lowpass filter (FL) only. Alternatively, when the potentiometer wiper is moved to increase the gain, the highpass filter (FH) and the lowpass filter (FL) act together to control the open loop gain and this provides a bandpass response. <IMAGE>

Title: Selective calling receiver
Inventor: MIYAUCHI MOTOYA
IPC: H04W88/02
Filed: 1992-03-02
Abstract: A selective calling receiver comprises a receiving section (2) for receiving data including call numbers of individual receivers, function designation numbers and message data, an indicating unit (15) for indicating reception of the data, a RAM (5) for storing received message data, and an LCD (9) for displaying the stored message data. A resettable timer starts a time counting operation upon completion of reception of the message data following the call number of the receiver and outputs a signal upon expiration of a predetermined time period. When the receiver has subsequently received the call number of the receiver before the timer completes the time counting operation, it stores in the RAM (5) all message data received before completion of the time counting operation. The receiver starts an indicating operation in response to the output signal from the timer produced upon completion of the time counting operation, and displays the message data stored in the RAM (5) in priority order. <IMAGE>

Title: A system for controlling emergency rescue operation of an elevator in a case ofpower outage
Inventor: SONODA MICHIYOSHI
IPC: B66B3/02
Filed: 1992-06-23
Abstract: A system for controlling emergency rescue operation of an elevator in the case of power outage comprises an emergency power supply 103 which is operated upon detection of the power outage and terminates by timing out of either of two timers. The first time NRXT counts a time starting from the detection of the occurrence of the power outage and times out after a predetermined time as long as the elevator car is located outside a door zone in which passengers could be rescued through an elevator door. The second timer counts a shorter time which starts whenever an elevator car is located within the door zone. The first timer thus allows the maximum time provided by the emergency power supply for the lift car to reach a door zone, while the second timer allows the emergency power to be cut off rapidly, and conserve emergency power, in the event the lift car is already close to a door zone. <IMAGE>

Title: DC Motor-Generator Dynamic Feedback Control Circuit
Inventor: YANG TAI-HER
IPC: H02P7/34
Filed: 1992-07-30
Abstract: A dynamic current feedback control circuit for a magnetizing type shunt or series or compound DC motor-generator comprises the motor A101 having an auxiliary shunt field winding F101 and an auxiliary current-follower type DC motor M101 whose speed depends on the main motor armature current and which drives an auxiliary generator G101 to constitute a feedback unit. The auxiliary generator output is fed to the auxiliary field of the main motor-generator, to assist excitation with the same polarity as the field winding of the main motor-generator, or to apply differential magnetizing with different polarity against the field winding of the main motor-generator. A control interface Cl101 may control output voltage or output impedance from the auxiliary generator for controlling the output current. Such control is also applicable to a generator or dynamo motor, which may replace an expensive magnetic saturation amplifier or other complicated solid and dynamo switch loop to become an independent dynamo, endurable and reliable control system. <IMAGE>

Title: Retail credit cards.
Inventor: BYRNE THOMAS VINCENT
IPC: B42D15/10
Filed: 1994-03-29
Abstract: In a scheme in which a single uniquely coded card is issued in respect of a plurality of associated subscribers, the card comprises a plurality of mutually separable panels (30, 31) each of which panels bears the same readable data. The data is preferably bar-coded, but may be in OCR characters, or encoded in a magnetic stripe, or in any other machine readable form. As described a main panel (30) (e.g. for the principal subscriber) is of the same size as a conventional credit card, and subsidiary panels (31) (e.g. for associate subscribers) are smaller and are apertured (33) for receipt of a key ring or the like. To ensure reliable registration of subscribers with the issuer, each card must be uniquely associated with a corresponding application form. To this end preceded cards are firstly temporarily mounted on respective application forms, and the forms are then uniquely encoded by a reader/printer apparatus (Fig. 2, not shown) which reads the data from the card and transcribes identification data therefrom onto the form. The printer may be an ink jet printer. <IMAGE>
