Title: Improvements in and relating to number generation
Inventor: THROWER KEITH REX
IPC: G06F7/58
Filed: 1982-01-25
Abstract: A number generator is shown for producing successive sequences of 3- bit binary numbers, each binary number in each sequence being different from all the other binary numbers in that sequence and the binary numbers being pseudo- randomly and differently arranged in each sequence. The shift register 5 has two of its stages, C and E, feeding their outputs to a modulo-two adder 6 which feeds the result back to stage A for clocking through in response to clock signals on line 8. In this way, successive 5-bit pseudo-random binary numbers are produced in the shift register. The outputs of stages C, D and E are connected to a memory 16. A comparator 38 compared the 2- bit binary number in stages A and B with a predetermined 2-bit number, P, on a line 30, and up-dates the memory 16 each time correspondence is detected, so as to change the memory output on lines 10, 12 and 14. In this way, only eight of the 3-bit numbers appearing in stages C, D and E during the 31-stage cycle of the register 5 are selected for the output, and the selected numbers form a sequence of non-repeated numbers. When the value of P is changed, a different sequence of these numbers is produced. <IMAGE>

Title: Improvements relating to disc brakes
Inventor: WILLIAMS FRANCIS VERNON
IPC: F16D55/00
Filed: 1982-08-03
Abstract: The brake comprises a caliper (3) slidably mounted on a first torque taking member (1) by means of (a) pin sliding connection(s), the caliper (3) being open-topped for the insertion and removal of friction pad assemblies (27, 29). A supplementary torque taking member (5) is detachably secured to the first torque taking member (1) and has a pair of finger- like projections (15, 17) which, in use, engage in complementary recesses (19) in the friction pad assemblies (27, 29) and take all of the drag forces.

Title: Monitoring coal extraction
Inventor: CLARKE JAMES WILLIAM
IPC: C10G1/06
Filed: 1982-11-19
Abstract: The amount of donatable hydrogen in a hydrogen donor liquid solvent used in an extraction of coal process may be assessed by diluting a sample of the solvent with an aromatic liquid diluent, carrying out a test extraction of the coal with the diluted solvent under standard conditions, determining the extraction yield and, preferably, comparing the yield with yields of calibration tests. The liquid yield may be determined by a quinoline insolubility test and the gas yield by collecting and analysing evolved gas. The method is reliable and quicker than known methods of characterising solvents, and may be used to control coal extraction processes.

Title: Pivotal mount and stand incorporating such a mount
Inventor: CHINN HERBERT
IPC: A61N5/00
Filed: 1983-03-10
Abstract: A stand (10) for a suntan system has a base (13) with two horizontal legs (14) at right angles, and an upright mounting member (15) extending from the base (13) but facing at an angle of 221 DIVIDED 2 DEG  to the centre-line bisecting the angle between the legs. The top end of the mounting member (15) forms a face portion, inclined downwardly at 221 DIVIDED 2 DEG , and carrying a pivotal mount (12) for an arm (17), which in turn carries a panel (11) of ultraviolet lamps. A pivot pin (20) (Figure 4) on the arm (17) is inclined at 221 DIVIDED 2 DEG  to the arm axis. In use, the angles between the parts are additive in some positions and cancel out in other positions. The arm can therefore have two limit positions, one directly above the centre-line of the base (13) and the other directly above one leg (14) for compact storage in the corner of a room. In each limit position, the arm is horizontal, but movement from one to the other causes a rotation about the axis of the arm, bringing the panel (11) from the horizontal position when the arm is central, to the vertical position when the arm is folded above the leg for storage. <IMAGE>

Title: Intraframe coding and decoding equipment
Inventor: KURODA HIDEO
IPC: H04N7/62
Filed: 1983-05-04
Abstract: Intraframe coding and decoding equipment are used in a communication network for digital video signals. Video signal sources which have various frequency deviations are transmitted by the communication network. Each of the intraframe coding and decoding equipment items has a locked sampling coding algorithm which is suitable for an input video signal with high frequency precision and a nonlocked sampling coding algorithm which is suitable for an input video signal with low frequency precision. It is determined whether or not the frequency precision (i.e., the frequency deviation of the sync signal) falls within a predetermined range. One of the coding algorithms is selected in accordance with a detection result. The coding algorithm can be selected in accordance with a decoding algorithm of a receiving-side equipment. Switching of the coding algorithms is performed simultaneously with switching of the clock signals of the locked and unlocked sampling clocks.

Patent GB-2155709-A (GB)
Title: Battery charging
Inventor: GEORGE WILLIAM
IPC: H02J7/00
Filed: 1985-03-13
Abstract: The voltage across a battery B to be recharged is compared by a voltage control circuit (105) (Fig. 6), with a reference voltage from a reference voltage circuit (107), and if below the reference level, causes circuitry to allow charging of the battery B through a low resistor Ro and thyristors TH1 and TH2 in series between a secondary centre tap and the secondary ends. Firing of the thyristors TH1 and TH2 occurs in alternation, the firing point being controlled by a phase shifted signal from a phase shifter circuit 101 and a bias signal from a current control circuit (104) and subsequently the voltage control circuit (105) to a thyristor drive circuit 102. The current control circuit (104) senses the charging current through the resistor Ro and holds its level constant until the battery voltage reaches a predetermined level at which the voltage control circuit (105) overrides the current control circuit (104) and so controls the charging current that the battery voltage remains constant until the charging current falls to a predetermined low level at which a low level current trip circuit (106) alters the voltage sensed by the voltage control circuit (105). Thereupon the voltage control circuit (105) holds the charging current at a low "care and maintenance" level. An alternative embodiment (Figs 10, 11), charges the battery via a full wave rectifier and one thyristor and has means which, if the battery voltage is initially below a predetermined flat level, controls the thyristor to supply trains of charging current pulses to the battery, the pulses increasing in current amplitude within each train. When the battery voltage exceeds the flat level, the charging is thereafter effected according to the above constant current and constant voltage stages. <IMAGE>

Title: Feed means for comminution apparatus
Inventor: KLINNER WILFRED ERWIN
IPC: B26D7/06
Filed: 1985-05-17
Abstract: In a harvester 205, a stream of crop 206, is fed by a conventional auger 207 into a pair of pre- feed rollers 209, 210 and then into a pair of feed rollers 211, 212. The latter force the crop into the multi-disc cutting rotor 215 beneath a series of individually spring-loaded packer arms 217 pivoted upstream of rotor 215. The presence of the pre-feed rollers 209, 210 upstream of the feed rollers 211, 212 allows favourable transverse alignment of the crop to be effected, i.e. with the stems of the crop aligned with the width dimension of the harvester. This is achieved by maintaining the peripheral speed of the pre-feed rollers 209, 210 at a greater value than that of the feed rollers 211, 212. <IMAGE>
