Title: Improvements relating to ignition system distributors
IPC: F02P3/00
Filed: 1979-09-28
Abstract: A distributor shaft 4 carrying an electrode 3 of an ignition system is connected to a transformer coil 9, 10 by means of a high tension lead incorporating a conductive member 6. Separated from the conductive member (6) by an air gap 17 is a plate 7 connected to earth. An electromagnetic switch 13 in the primary supply circuit of the transformer coil will operate intermittently as flux is produced through the core 15 of the transformer to create a continuous sequence of high voltage pulses to the high tension lead 5 which will be dissipated to earth either via the plate 7 or through one of the spark plugs 1 if the gap between the electrode 3 and a terminal 2 swept by the electrode is smaller than the air gap 17. This arrangement dispenses with the usual contact breaker switch and thus simplifies the ignition system. A small air gap 16 is provided. <IMAGE>

Title: Apparatus for separating curd fines from whey
IPC: A01J25/11
Filed: 1980-05-14
Abstract: Screening apparatus comprises a closed housing (1) having an inlet (7) to deliver whey that contains a substantial portion or curd fines onto an inclined stationary trough (8) which delivers it onto a stationary separating trough (13) whose floor comprises a screen (20) which is inclined in the opposite direction from the trough (8). In passing from trough (8) to screen (20) the whey passes through a slot which distributes it in a thin layer across the screen. In flowing down the screen most of the whey drains through the screen into bin (27), while the remaining whey and the fines are collected in a separate bin (28) in the form of a slurry. This avoids any unacceptable change in texture and colour of the fines, which can therefore be pumped back to a cheese making vat. Pumps (32, 33) are controlled by level sensor (34). Screen (20) is stretched across the bottom of trough (13) between two rods which engage in brackets on the trough sides (Figure 4 not shown). <IMAGE>
Patent GB-2076242-A (GB)
Title: Television system scheduler
IPC: H01H43/00
Filed: 1978-10-02
Abstract: A television receiver includes a chassis (12) having a digital tuner (14) for generating local oscillator signals for tuning the receiver to respective channels in response to binary signals representing corresponding channel numbers and a signal processing unit (18) for controlling at least one characteristic of the receiver, such as the sound level, in response to binary signals representing the controllable characteristic. The receiver also includes a microcomputer (34) including a RAM (130) (Random Access Memory) with at least one memory location for storing binary signals representing the present time and a plurality of memory locations for storing binary signals representing future times and channel numbers of channels to be tuned at those times. A control portion (100) of the microcomputer causes binary signals representing the channel number associated with a future time to be coupled to the digital tuner when the present time matches the future time. A keyboard (32) having ten digit keys for generating binary signals representing the decimal digits between 0 and 9 and two characteristic keys to generate binary signals representing an increase and a decrease in the controllable characteristic is provided to enable user control of various operating modes of the receiver. When a user operates digit keys to form a number within a predetermined range of channel numbers e.g. 2-83, the control portion of the microcomputer causes the channel to be tuned. Subsequently operation of digit keys within the predetermined range of channel numbers causes the channel to be changed and operation of the characteristic keys causes the controllable characteristic to change. When a user operates digit keys to form a number not within the predetermined range of channel numbers, the control portion of the microcomputer causes power to be decoupled from the chassis. Subsequently, in response to the operation of a predetermined one of the characteristic keys, the control portion causes binary signals generated in response to the operation of the digit keys to be selectively coupled to either the RAM location associated with the present time or to the RAM location for future selections.

Title: Synthetic aperture radar
Inventor: VOLES ROGER
IPC: G01S13/90
Filed: 1980-10-13
Abstract: In order to compensate for lateral motion of the antenna of an SAR which forms a synthetic aperture of N + 1 returns, for each range interval r the first N returns are used to estimate the phase of a map point  tau rN/2 phi rN/2 and the estimated phase  phi rN/2 used to correct the N + 1th return. The (N + 1)th corrected returns of a plurality of range intervals are then used to estimate the lateral motion phase error  mu p which is used to compensate the (N + 1)th returns of all range intervals r for the error due to lateral motion. The compensated (N + 1)th returns are used in the next aperture where the previous steps are repeated for the (N + 2)th returns, and soon. The initial N returns may be compensated in the manner described in application 7936319. <IMAGE>

Title: Braking Unwinding Spool in Ribbon Cassette
IPC: B41J33/52
Filed: 1980-12-08
Abstract: A ribbon cassette (1) for use in typewriters comprises a casing (2) in which a supply spool (4) is mounted for rotation together with a toothed disc (20) on a common pin (3). A tensioning and guiding device (10) which also acts as a brake for the supply spool (4) consists of a bent wire having a first section (11), fixed at its free end to the casing at (2a), a second section (12) extending substantially perpendicularly to the first section and a junction portion (14) which is adapted to engage in the toothed disc (20) to prevent rotation of the supply spool. Ribbon unwound from the supply spool is guided round the free end (15) of the second section, which free end may carry a roller (17). The tensioning and guiding device is arranged such that, when tension is applied to the ribbon to unwind it from the supply spool, the second section (12) pivots about portion (14) by a predetermined extent before the detent portion becomes disengaged from the toothed disc on movement of the first section. A take up spool (7) is driven by spikes on a wheel (8) penetrating into the ribbon being wound onto spool (7). The spool (7) is carried on a pivotable lever (5) so that spool (7) pivots towards the supply spool (4) as the diameter of the ribbon wound on spool (7) increases. The device (10) delays movement of the supply spool until slightly after drive wheel (8) has started rotating so that the raising of the ribbon (16) to its printing position is not hindered. <IMAGE>
