Title: Apparatus for placing objects on trays
IPC: B65G37/00
Filed: 1969-11-28
Abstract: 1,243,567. Packaging machine; endless conveyers. SOLLICH oHG. 28 Nov., 1969 [23 Dec., 1968], No. 58376/69. Headings B8A and B8C. Chocolates are transferred from a conveyer belt 11 into trays 17 which are carried at a constant velocity to the transfer station on a conveyer belt 14. The conveyer belts 11 and 14 are driven by the same motor in order that they may have the same velocity. However, the conveyer belt 11 is driven through a magnetic coupling 19 which is opened, and hence the conveyer belt 11 stopped, for a short duration by a signal from a photo-electric call 18 arranged at the transfer station to detect the passage of a joint between two trays 17. The chocolates are moved into the centre of the conveyer belt 11 by two obliquely converging belts 21 which are driven at such a speed that the velocity component of the two belts 21 in the direction of motion of the conveyer belt 11 is equal to the velocity of the conveyer belt 11.

Abstract: 1278186 Cables STANDARD TELEPHONES & CABLES Ltd 17 Dec 1970 59923/70 Heading H1A A method of manufacturing a coaxial cable of the kind comprising an inner conductor 2, dielectric 3, a metallic tape return conductor 4, with the longitudinal edges of the tape overlapping at 6, and a plastics sheath 5, comprises the steps of heating the return conductor by r.f. energy before or after application of the sheath, whilst applying external pressure in order to melt the outer surface of the dielectric and hence bring the return conductor and dielectric into more intimate contact, e.g. at 7. The return conductor can be copper and the dielectric and outer sheath, polyethylene. Bonding of the return conductor to the dielectric and/or sheath can be achieved by pre-treating the surfaces with a bonding agent. Alternatively, the surfaces may be treated with an agent preventing bonding of the various layers, if this is desired. The inner conductor may be solid copper or, as shown, a steel strengthening core 1 with a copper tape 2 thereabout.

Abstract: 1368459 Money dispensers GLORY KOGYO KK 29 Dec 1971 [29 Dec 1970 30 Sept 1971] 60283/71 Heading G4X A money dispensing machine comprises a memory section 1 for storing monetary data corresponding to the money to be dispensed, a selection control section 2 which successively reads out from the memory section, in a predetermined order, the monetary kinds to be dispensed and a driving control section 3 which controls a money dispensing mechanism to dispense the required monetary kinds in the order read out from the memory section. In the embodiment shown, for dispensing four monetary kinds in particular four denominations of banknote, the memory section comprises four flip-flops FF1-FF4 with corresponding setinputs a 1 -a 4  and outputs F connected to respective AND gates G1-G4. The outputs F of flip-flops FF1-FF3 are connected through diodes d to certain of lines l 1 -l 4  which form the other inputs of AND gates G1-G4, thus when these flip-flops are in the set condition one input of the AND gates to which they are connected through the diode matrix is rendered "0" When, for example, all four flip-flops are set only AND gate G1 is opened, and on depression of start push-button PB a driving motor M is energized to rotate a money enclosing drum (the four denominations of banknote being located at different angular position in the drum) until the required denomination is positioned for dispensing at which point a signal b 1  is issued. Detection unit S 1 , having inputs g 1  and b 1 , issues a signal to stop the motor and the required number of pieces of money of the kind associated with flip-flop FF1 is dispensed, a completion signal EOT1, which resets flip-flop FF1, being obtained at the end of this operation. With flip-flop FF1 now reset gate G2 is opened and the dispensing operation for the associated denomination proceeds as above. In another embodiment (Figs. 1 and 2, not shown) signals from a check circuit (6) indicative of the denominations necessary for the dispensation of an amount entered via keyboard (1), or signals from a manually operated denomination selector (2), or utilized in relay switching circuits (20) to (24) to produce signals for controlling the position of a money dispensing drum so that the required denomination or denominations are dispensed.

Patent GB-2008397-A (GB)
Title: Wall reclining rockling chair
IPC: A47C1/032
Filed: 1978-11-15
Abstract: A reclinable chair is rockable on a frame which is movable forwardly on a base. The chair and frame are supported on the base on a pair of facing channels which slope downwardly from the rear to the front of the base. The frame and base are locked together in the rear and forward positions, the lock at the rear being released when the activating handle for the legrest at the side of the chair is raised 10 DEG  or 15 DEG . The further movement of the handle extends the legrest forwardly of the seat. The seating of the occupant in the chair assists in the movement of the chair to the forward position during which a spring between the frame and base is tensioned for returning the chair to the rear position when the occupant leaves the seat and permits the springs of the seat to move upwardly and release the front latch. A lever prevents the rocking of the chair until it reaches the forward position where it is stopped in its forward movement to release the chair for rocking. When in forward position, the back of the chair may be reclined and the legrest may be extended in which position a ratchet mechanism becomes effective to prevent the chair from rocking or tilting forwardly.

Title: Regulated power supplies
IPC: G08C19/02
Filed: 1979-03-12
Abstract: A current transducer and power unit CTPU supplies power to a current transmitter CTX via a Zener Barrier ZB. In the CTPU, the output current through R1 is matched by a current through R2, and differential amplifier A1 connected to resistors R1 R2 controls transistor Q1 to ensure this, so that VOUT across resistor R3 corresponds to the current in R2 and hence in R1. Resistor R4 is included between R2 and Q1, and the voltage at its lower end (which is tied to the voltage at A1 output) is compared in a second differential amplifier Q4 Q5 with a reference voltage from ZD1 to control a current control transistor Q3 which feeds R1 and R2. This keeps the voltage at the lower end of R4 constant and, according to the value of R4, regulates the output of the CTPU, a point in ZB or the input to CTX. <IMAGE>

Patent GB-2042840-A (GB)
Title: RC-bridge Oscillator
IPC: H03B5/04
Filed: 1979-11-08
Abstract: An operational amplifier giving 90 DEG  phase-shift at the oscillating frequency has frequency independent feed-back provided by a voltage divider, incorporating series and parallel-connected resistors R1-R5, limiting diodes D1, D2 and a thermistor T, and frequency determining positive feedback 1, 2. The thermistor T compensates the temperature changes of the limiting diodes, while the series or parallel connected resistors are adjusted for balancing this temperature compensation in order to ensure very slight voltage level changes of the sense tending to stabilise the frequency. Moreover, the RC-value of the positive, feed-back branch, and the division ratio of the frequency- independent branch, are determined in dependence on the basic amplification of the operational amplifier, the first break-point frequency, and the intended operating frequency. Buffer stages or amplifiers can be inserted between the oscillator and the load. If a square-wave signal is required on the output, a comparator is used instead of the buffer stage. <IMAGE>
