Patent GB-2080578-A (GB)
Title: Calendars
IPC: G09D3/10
Filed: 1980-05-03
Abstract: A 'perpetual' calendar has a first table 102 which consists of a succession of years and the calendar months laid out to give a corresponding reference number which is equal to a date number in a month i.e. a number between 1 and 31. As shown the years are laid out in horizontal rows (with the years in chronological order) and vertical columns; the years which have an identical dates to days of the week relationship always appear in the same column. The calendar also has a second table 104 and cursor 106, the table 104 comprising rows of numbers commencing with 1 or a number greater than 1 and terminating in 31 or a number less than 31, and embodies all of the 28 possible arrangements of the dates of a calendar month in relation to the 7 days of the week. The cursor has a window marked with the named days of the week to isolate the relevant group of numbers which form the month selected, and an arrow 108 to indicate the reference number obtained from the first table. The calendar is used by determining the reference number from the first table for the year and month selected (e.g. 13 for February 2000) and moving the cursor over the second table until the arrow on the cursor points to the reference number on the second table. The calendar for the year and month selected will then be shown in the window of the cursor. <IMAGE>

Title: An adder of electrical pulses using an electric motor with position control
IPC: G01C22/02
Filed: 1980-06-03
Abstract: In an adder of pulses, for example giving the number of revolutions made by a rotatable member in measuring the distance travelled by a vehicle, a transistor 17 is rendered conductive when the trigger circuit 13, 14 is triggered by a pulse from a divider 9, and an electric motor 18 is advanced until a position pick-off 20 detects a predetermined rotation of the motor and delivers a signal to the reset input of the trigger circuit to cause the motor to stop. In this way the motor (which may be dc, synchronous, asynchronous) is driven step by step and may replace a stepping motor. <IMAGE>
Patent GB-2077537-A (GB)
Title: Digitising circuitry
IPC: G01L1/22
Filed: 1980-06-05
Abstract: Circuitry for digitising the signal produced by for example a strain gauge bridge (10) comprises a signal processing channel (20) including an amplifier and A-D converter connected to the bridge output by a semi-conductor switch (18) controlled by a microprocessor (22) which periodically changes over the switch (18) so as to digitise a calibration signal derived from the energising source (12) for the bridge by means of a signal attenuating high stability amplifier (32) and a high stability voltage divider (30). The microprocessor scales the output of the channel (20) by a multiplying factor the magnitude of which is such that its product with the value ale represented by the digitised calibration signal is always constant. In this way, any drift is compensated for by change in the magnitude of the multiplying factor. <IMAGE>

Title: Data storage system for a computer
IPC: G06F7/22
Filed: 1980-09-16
Abstract: The system includes one or more host processor interfaces including controllers 12 connected to a main high speed "cache" memory 22 and to disk store interfaces 16 including local controllers, and a supervisory control processor 24. The system responds to requests by the host computer to store and to retrieve information in the format of a conventional tape drive assembly. The data, however, is actually stored or retrieved in piecemeal form from a plurality of disk storage drives 20a to 20n so that the data management system functionally mimics a tape drive and accepts and produces data in serial (tape) format, but in fact stores the data in available spaces in disk units. Data passes in each direction through a main memory 22 under the control of a processor 24 which allocates blocks of a "tape" file to the disk drives. Interfaces 12a to 12n between the computer 10 and memory 22 can contain data buffers and interface between serial format on the computer side and parallel format on the memory side. Interfaces 16a to 16n between the disk drives 20 and memory 22 can also contain data buffers and interface between serial format on the disk drive side and parallel format on the memory side. <IMAGE>

Patent GB-2084357-A (GB)
Title: Stabilizing Circuit for Controlled Inverter-Motor System
IPC: H02P27/06
Filed: 1981-09-10
Abstract: Stabilized operation of an inverter (25) and an a-c motor (41), driven by the inverter, is obtained in the presence of sudden undesired load changes by controlling the inverter so that both the amplitude and frequency of the inverter output a-c voltage are functions of the d-c bus voltage. Thus, whenever an abrupt abnormal load change causes the d-c bus voltage to vary, a frequency change occurs to compensate for the load change and to stabilize the bus voltage by changing the motor speed. When there is a normal variation in load demand, necessitating a different steady state motor speed, a set point or reference voltage may be adjusted to change the amplitude and frequency of the inverter output voltage to the levels needed to drive the motor at the new required speed. <IMAGE>

Patent GB-2124050-A (GB)
Title: Semiconductor switching circuits
Inventor: FARROW VICTOR
IPC: H03K17/0424
Filed: 1983-06-28
Abstract: Speed of switching of semiconductor devices, such as transistor 10, is improved by providing base drive which is a function of load current by means of current transformer 14; switch 17 reverses the polarity of the base drive and causes a switching transition of transistor 10, extracting excess charge from the base. In a modified arrangement (Fig. 3), an auxiliary transformer (T5) is connected in series with the main transformer (T1) the outputs of the two transformers being summed to provide the base drive current. The auxiliary transformer is arranged to saturate early in the switching cycle, thus providing a boost to the base drive at the commencement of each cycle, when base drive current would otherwise be low. <IMAGE>
