Abstract: 916,739. Driving magnetic tapes. MIDWESTERN INSTRUMENTS Inc. Nov. 14, 1961, No. 40655/61. Class 40 (2). [Also in Group XXIX] A reversible tape drive is provided by contradriven capstans 44, 46, driven by pulleys 106 and an endless belt (Fig. 2, not shown). The tape-driving surfaces 150 are of a porous material and a continuous low positive air-pressure applied through a pneumatic system 124, 84, 144 tends to lift the tape out of driving engagement. Members 172, 174, liftable as in Fig. 3 for tape-loading, are lowerable into pneumatic engagement with outlets 192 whereupon a higher air-pressure, emerging from slots 188, overcomes the tape-lifting pressure and forces the tape drivingly against the capstan surfaces 150. For braking, similar slots in a member 294 guide the higher air-pressure to snub the tape against a flat surface 308 on the member 174. Push-buttons 37 actuate a system of solenoidoperated pneumatic valves (see Group XXIX) which select the drives and brake. A vacuum column servo system 38 of conventional type acts on the trailing tape-loop in concert with the trailing capstan tape-lifting pressure to maintain a constant tape tension across the transducing means 28.

Filed: 1971-09-02
Abstract: 1305849 Milking apparatus P DOUZIECH 2 Sept 1971 [7 Sept 1970 13 Oct 1970] 40997/71 Heading A1M A milking plant particularly for ewes comprises radially disposed stalls 1 on a platform 2 rotated by a motor 21. Ewes enter the stalls 1 via a trench 3 and a ramp 4, a gate 5 being operated by electric contacts 7, 8 which are themselves actuated by open stall gates 25 which when closed hold the ewes by the neck. Ewes alight, after milking, at ramp 9 passing through non-return gate 10. Each gate 25 includes a roller which normally travels in a circular guide 29 thereby keeping the stalls 1 closed. Each revolution of the platform 2 causes a shaft mounted beneath the platform 2 to rotate through a predetermined arc until one of two pins on the shaft elevates one of two respective arms. This raised arm contacts projections on alternate stalls 1. Each such contact actuates a switch 31, causing the gate roller to travel along a spur 30 thereby opening the respective stall 1 and allowing exit of a ewe. The roller then travels along a spur 32, which closes the stall 1 and actuates the contacts 7, 8 allowing access to the now empty stall 1. The intervening stalls are opened and closed on the next revolution of the platform, subsequent revolutions not operating the gates until a complete revolution of the shaft is effected. Automatic filling of troughs 12 occurs when the open gates 25 pass through hoppers 11. Milking apparatus 13 is connected to milking cups via a central joint 14 and a mobile conduit 15 which is supported by a rigid fitting 16. In a modification, a larger number of stalls is worked by two sets of diametrically opposed ramps and spurs.

Title: Improvements in or relating to electric pulse code translators
Inventor: LAMBOURN EDWARD HARRY
IPC: H03M1/80
Filed: 1959-12-07
Abstract: 873,944. Pulse code modulation systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 7, 1959, No. 41589/59. Class 40(5) Relates to apparatus for converting incoming pulse groups representing amplitude levels in a unit-distance binary code into corresponding pulse groups in the simple binary code. As described, the incoming signals are represented by a unit-disparity unit-distance code of the type described in Specification 849,891 having an odd number 2m-1 digits in each code group and in which each group has either m or m-1 pulses, code groups corresponding to successive levels differing only in one digit. The incoming pulses are supplied via a series to parallel converter 22 to windings 37 on saturable cores n to n-5 some of the windings being wound "straight" and some "reverse" in accordance with the code. The number of cores is equal to half the number of levels and each core produces an output-pulse in response to either of the pair of corresponding code groups representing successive levels, since the digit which is present in one code group and absent in the other group of that pair has no corresponding winding on the core. In order to distinguish between the two levels of a pair a further saturable core p+1 with seven windings corresponding to the seven digits of the U.D. code is arranged to respond only when four pulses are present in the incoming code group. Suitable biasing is provided by coils 38, 39, supplied by a source 24 through an adjustable resistor 25. The cores n to n-5 also carry coils 40 all wound in the same direction and arranged in accordance with a six digit simple binary code, which are connected via rectifiers 32 to 36 to a conventional weighting network 26 providing an output proportional to the corresponding signal sample. The core p+1 is provided with an output winding 41 which provides the least significant digit of the simple binary code and is connected via a rectifier 31 to the weighting network. The rectifiers 31 to 36 eliminate the unwanted reverse output pulses produced when each code group is removed.

Abstract: 1380596 Automatic control of voltage and current SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 7 Sept 1972 [10 Sept 1971] 41665/72 Heading G3R [Also in Division H2] A D. C. circuit includes a regulation and cut-off device connected in series between a source and load. The voltage across the load is sensed and regulated by controlling the series device, and the latter is caused to cut off the supply if the load voltage falls below a predetermined value. A further circuit senses the load current and actuates the regulation device if the current tends to exceed a given limit. In the arrangement shown, a lamp L is supplied by a battery 1 through power transistors Q6, Q7 connected in Darlington relation with a transistor Q8. A voltage regulator circuit 4 compares the lamp voltage, sensed by a potentiometer comprising transistor Q3 and resistors R 1 , P 1 , R 2 , with a Zener diode DZ1 and controls transistor Q8 accordingly to regulate the lamp voltage. If the latter should decrease excessively, a Zener diode DZ2 is blocked and transistor Q3 turns off so that transistor Q8 ceases to be energized and the supply to the lamp is cut off, thus preventing over-discharge of the battery. The charging of a capacitor C2 enables the circuit to start up when contacts S1 are closed. A current-limiting circuit 3 senses the voltage drop across resistors R25, R26, and excessive current causes transistors Q9, Q10 to turn on and reduce the base bias of transistor Q8, thus limiting the lamp current. If this action reduces the voltage across the lamp sufficiently, the supply is cut off by the voltage regulator as before to prevent damage to the lamp and battery.
