Filed: 1963-10-11
Abstract: 1,024,754. Pneumatic despatch apparatus. STANDARD TELEPHONES & CABLES Ltd. Oct. 11, 1963 [Oct. 16, 1962], No. 40199/63. Heading B8A. [Also in Division E2] In a pneumatic tube despatch system particularly for use in a drive-in service at a bank &c. in which carriers 1, Fig. 9 (not shown), move between teller and customer stations, the carriers 1, Fig. 2, are not removable from the carrier tube and have hinged covers 2 which are automatically opened at the respective stations by the application of pressure in two directions. The carriers comprise a trough section 1, Fig. 2, connected between end plates 10 and having the open side enclosed by the cover 2 which has hinge shafts 3, 4 at opposite ends, engaged by releasable catch devices 5, 6 (see also Division E2). Either of the shafts 3, 4 may be released for hinging the cam 2 about the other shaft so that in each case (as in Fig. 9) the uppermost shaft is released to enable the cover 2 to fall open at both the customer and teller stations. Springs 31 engaged by flanges 2a of the doors assist in forcing the door outwards when released by the catches. The catches are released by first applying pressure to the door 2 so that the shafts 3, 4 resting in spring-loaded fork members 6 are depressed clear of hook members 5. Pressure is then applied to one of two pivoted plates 17, at opposite ends of the carrier 1, which operate to swing the hook members 5 clear of the selected shafts 3, 4. On release of pressure on the door 2 the springs 31 are free to press the door 2 clear of the catches so that it falls open. Each of the stations as at Fig. 5 (not shown) is provided with a sliding door 39 move d by a chain 70 under the control of the teller' The door 39 carries a roller 50 on parallel arms 49 which operate to depress the carrier door 2 as it moves over the access opening. The arms 49 carry a shaft 53 the ends of which move over cams 47, 47a to depress the roller 50 into engagement with the carrier door 2. A plunger 64 is also provided to depress the uppermost hinged plates 17 of the carrier and is actuated through a crank mechanism 68, 69 and Bowden cable 66. Catch means 36 retain the carriers in position at each station.

Title: Machine for embossing objects
IPC: B44B5/00
Filed: 1975-10-01
Abstract: 1522186 Selective printing H NIELSEN & SON MASKINFABRIK AS 1 Oct 1975 [1 Oct 1974] 40223/75 Heading B6F [Also in Division B3]  Machine for embossing an object such as a steel sheet 7 comprises an embossing head 18 mounted for vertical reciprocation on a piston 15 of a cylinder (14), Fig. 1 (not shown), suspended from the machine frame. A shaft 19 rotatable by a hydraulic motor 25, supports a plurality of embossing wheels 1-4, each rotatable to bring one character 20 at a time into embossing position, and so formed that the wheels are pressed down towards the sheet 7 one by one when the shaft is rotated. The shaft comprises sheaves 21-24 equally eccentric and spaced at equal angles about the shaft. The wheels mesh with respective gears 36 driven by a motor 39 for adjustment of the wheel relative to each other and to the shaft. To prevent the wheels rotating with the shaft, braking fingers (28) Fig. 4 (not shown) engage the teeth of the wheels. In use the head is lowered by the cylinder 14 until legs 34 engage the sheet 7, the distance between the base of the legs and the axis of the shaft 19 determining the embossing depth. The pressure exerted by the cylinder 14 is greater than the pressure exerted by shaft 19 to prevent the head 18 lifting off the sheet 7. Adjustable legs (35) (Figs. 5 or 6) may be provided to allow for wear of the characters 20. To maintain a predetermined embossing pressure regardless of unevenness in the surface of the sheet 7, legs (47) (Figs. 7 and 8) include cup springs (48) surrounding vertically reciprocable spindles (49). The construction of the legs is such that when the head is lowered until the springs are compressed, none of the wheels engage the sheet 7. The shaft drive motor exerts a greater pressure than the cylinder 14, the head 18 lifting during embossing corresponding to the penetration depth. An encoder 41 indicates the angular position of the shaft. By electronically comparing the measured values of the encoder 41 and of an encoder 52 measuring the pressure in the inlet 51 to the drive motor 25 a predetermined embossing pressure can be maintained. A pressure measuring means 42 of the cylinder 14 releases the embossing pressure-when a predetermined limit is reached.

Abstract: 1,145,898. Suppressed carrier modulation. FERNSEH G.m.b.H. 9 Sept., 1966 [10 Sept., 1965], No. 40333/66. Heading H3R. A suppressed carrier modulator comprises two emitter-coupled pairs 1, 2 and 3, 4, the carrier HF being supplied to the bases of two of the transistors 2, 3, and the modulation NF controlling the current through the emitter loads. The carrier is in anti-phase at the collectors of transistors 2 and 4 and at the collectors of transistors 1 and 3 which are connected together respectively at each end of the tuned output load 18, 20 thereby suppressing the carrier. In Fig. 6 the modulation NF is supplied to a further emitter-coupled pair 22, 23 coupled to the emitters of transistors 1-4 by individual resistances 2R, the emitters being coupled at carrier frequency by capacitors 30 and 31 which have a high impedance at the modulating frequency. In a modification, Fig. 5 (not shown), the modulation is coupled to terminals 14 and 15 through a transformer, the transistors 22, 23 and 42 being omitted. The load coil 20 may be replaced by an output transformer (Fig. 1, not shown). Two modulators supplied with the carrier and modulation in quadrature phases produce a single sideband output in a common output load (Fig. 7, not shown). This may be used in a PAL colour television transmission system to provide a chrominance carrier displaced 25 c/s. from an input carrier.

Title: Method and apparatus for analysing an amplitude spectrum

Filed: 1968-08-26
Abstract: 1,209,512. Analogue/digital converter. COMMISSARIAT A L'ENERGIE ATOMIQUE. 26 Aug., 1968, No. 40719/68. Heading G4H. Apparatus for analysing the amplitude spectrmn of electric pulses from a detector 10 (Fig. 1) includes a generator 12 producing a direct current which is increased in steps at predetermined time intervals, the amplitude of the pulses and the current being compared and a pulse emitted when the amplitude is greater than the current (or vice versa) these pulses being counted and the amplitudes compared with the next step of the current. Alternatively, two reference currents (i 0 1<SP>,</SP> i 0 <SP>11</SP>, Fig. 3, not shown) which are varied simultaneously in steps, may be generated, a pulse being transmitted for counting when the amplitude of an electric pulse lies between the two currents. In the embodiment described for radio-activity borehole logging the reference currents are generated at a remote station B and compared by a trigger 18 at the detection head A, a current being directed by a diode 14 back to the remote station B when the amplitude of the pulses is smaller than the reference current i o  and a trigger 18 pulsing a counter 24 when the amplitude of the pulses exceeds the reference current. In the embodiment in which the amplitude of the pulses is compared with two reference currents two triggers (18<SP>1</SP>, 18<SP>11</SP>) compare the amplitude of the pulses with the reference currents and a device (40) delivers a counting signal when the amplitude of a pulse lies between the two threshold levels. The reference currents may be generated by the circuitry of Fig. 6 in which for each clock pulse from a source 26<SP>1</SP> a constant amount of current flows through field effect transistor 34<SP>1</SP> so that capacitor 32<SP>1</SP> charges up in equal steps, the terminal voltage of resistor 114 increasing proportionally. A current proportional to this voltage flows through the emitter of a transistor 118 and hence the current through a milliammeter 124 increases in a staircase fashion, this current being distributed between resistors 128, 130 to generate the reference currents.
