Abstract: 1,154,969. Digital transmission systems; transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. 4 Aug., 1967, No. 35853/67. Headings H3T and H4P. The invention provides a digital transmission system in which the potential level of the transmitted signal changes from a first level to a second (or vice versa) at the beginning of each bit and also changes from one level to the other at the centre of each bit of a particular state, see Fig. 3F. An encoder for converting input binary signals, in which the two bit-states are represented by two potential levels, to binary signals of the type defined above is described. A regenerator and receiver, comprising a regenerator followed by a decoder, are also described. At the transmitter, Fig. 1 (not shown), input unipolar binary signals Data I/P, Fig. 3, are gated with square wave clock signals A from an oscillator (see below), the clock signals having a repetition frequency twice the bitrate of the binary signals. The resulting signals D are gated with a bit-rate waveform C, the gate output E controlling a J-K bistable circuit which develops for transmission signals F of the type defined above. At the regenerator, Fig. 4 (not shown), the received signal, Line I/P, Fig. 6, is squared up and passed in true and complement form G, H to a bi-stable circuit whose output J, K passes passes both to a further bi-stable and to a clock circuit (described below), which extracts a clock signal P from the data. The clock signal P controls the further bi-stable whose output Q is the regenerated input data. The receiver comprises a regenerator as described above feeding a decoder, Fig. 7 (not shown). The regenerated signal and its complement R, R, Fig. 9, pass via filters to a buffer bi-stable whose output S, #S feeds monostables generating U, T. These are gated to give V, V being gated with a clock signal CC derived from the clock signal M of the regenerator. The output, Set 0, is applied to one side of a bi-stable. To the other side is applied Set 1 which is derived from V by way of an inverter, giving W, followed by a monostable, giving Y, and a gate fed by both W and Y. The bi-stable output is as DD and EE, identical to the original binary data signal. V and Y are gated to give a bit-rate clock, Strobe. The oscillator, Fig. 2, comprises crystal. X1 and inverters 21, 22. The interverters are formed of transistor-transistor logic integrated circuit NAND gates with the inputs commoned. Inductor L1 causes the inverters 21, 22 to act as class A amplifiers. The clock circuit, Fig. 5, is fed at 501, 502 by J, K,.Fig. 6. The-rectifier output L, L feeds a crystal filter comprising crystal X2 which oscillates at twice the bit-rate. The filter output passes to the transistor shown, whose output is the twice bit-rate clock M. Reference has been directed by the Comptroller to Specification 892,552.

Abstract: 872,294. Endless belt conveyers. MAVOR & COULSON Ltd. Nov. 27, 1957 [Dec. 1, 1956], No. 36805/56. Class 78 (1). In an endless belt conveyer the belt 3 is driven by a pulley 2 around which the lower run of the belt, after leaving the head pulley 1, is wrapped by snub pulleys 4, 5 the former of which is a longitudinally movable tensioning pulley. The grip of the belt on pulley 2 is increased by a short endless belt 10 travelling over pulleys 6, 7, 8, 9, the pulley 6 of which is carried by a longitudinally movable shaft 6A which is coupled to the shaft 4A of the belttensioning pulley 4 through a motion-decreasing device. The arrangement is such that upon increase of tension in the conveyer belt 3 the resulting movement of the pulley 4 towards the head pulley 1 is communicated through the device to cause a smaller movement of the pulley 6 away from the head pulley 1 to increase the tension in the belt 10. The motiondecreasing device consists of two pairs of pulleys 13, 14 connected by gearing 17, 18. A pair of ropes 15 extend from the pulleys 13 to the shaft 4A and a pair of ropes 16 extend from the pulleys 14 to the shaft 6A. The shaft 4A is supported in slots 20 to limit the amount of its longitudinal movement.

Title: Means in spinning or twisting machines for the radial shifting of rotary parts away from or towards belts by which they are driven
IPC: D01H7/22
Filed: 1965-08-27
Abstract: In a spinning &c. frame, means are provided for interrupting the spindle-drive by shifting a rotary part, i.e. the spindle or a tension-roller, towards or away from a driving-belt engaging the rotary part.  The latter is carried by a support releasably secured in a elongated slot in the spindle-rail which extends transversely of the belt, which support is movable along the slot, the means securing the support in the rail being tightened when the rotary part is in contact with the belt and being loosened when the rotary part is withdrawn from the belt.  In Figs. 1, 3 (not shown), a spindle 1 is secured in an open-ended slot 4 in a rail 3 by a threaded flange 6 and a nut 9.  The nut has external teeth so that a head 12 with similar internal teeth, and carrying a handle 11 and an extension 13, can be slipped on the nut from below in such a position that the handle projects at any desired angle to the rail.  The extrusion has a slot with curved and straight portions in which depends a pin 15 on the rail.  When the handle is rotated, the nut 9 is loosened, and the curved part of the slot moves along the pin until the latter lies at the start of the straight portion, whereupon it is possible to pull the handle and move the spindle away from the belt.  The movement of the spindle is assisted by a spring 22 and guided by depending flanges of the flange 6.  A leaf-spring 24 is freed to bring a brake-shoe against the inside or lower edge of the wharve.  In Figs. 5 and 7 (not shown), the pin 15 is movable with the handle and rides in a slot in the rail.  In Fig. 5, the spindle is moved to tension the belt which runs against a fixed tensioning pulley; in Fig. 7, the spindle is fixed, and the tension pulley is moved to tension the belt.

Abstract: 919,087. Containers' discharges. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 11, 1961 [Oct. 27, 1960], No. 37029/60. Class 78 (1). Toxic powder is fed from container 26 without spillage through the bottom outlet shown, the outlet being closed by movable closure member 7 which is wound at its two ends on tubes 9 and 10 so that, by turning one of the tubes by means of a key which engages at 14, material may flow out of the outlet via the square aperture formed in member 7. Spillage past the member 7 in the sideways direction is prevented by the surrounding rubber ring 16, and by the deflectable plate 3 which lies between ring 16 and member 7. Thus, when the valve aperture of member 7 is part way slid across the outlet, the thin gap so formed is closed by ring 16 which presses plate 3 downwards to block the gap. Two such units may be employed, each comprising a container and the valve device, and the two plates 1 may be brought together flush and the two valve devices opened so that the powder passes from one container to the other without fear of spillage.

Abstract: 1387607 Photo-electric measuring apparatus E SICK [trading as ERWIN SICK OPTIKELEKTRONIK] 11 Aug 1972 [11 Aug 1971] 37562/72 Heading G1A A two path photo-electric measuring system comprises a beam splitter 17 developing test (24) and reference (13) beams, a mirror 19 being tilted slightly from a position at right angles to the reference beam so that the reference beam falls on reference detector 15, while the measuring beam reflected at the beam splitter 17 on its return from the measurement zone 24 is directed via filter 10 to detector 14. In the arrangement of Fig.1 a  chopper 21 is used to enable reduction of the effects of ambient illumination by the processing circuit which may be as in Fig. 2. In this circuit, the detector outputs have D.C. and low frequency components removed in high pass filters 26, 27. The reference signal is rectified and filtered in low pass filter 28 before mixing with the test signal in a variable gain amplifier 29. The latter is controlled to maintain the reference signal component at a constant level, by the loop comprising low pass filter 34 and a regulator 35 in which the reference signal is compared with a reference voltage. The test signal passes on via high pass filter 33, and demodulator and low pass filter 36 to indicator 37. In an alternative arrangement Fig.3 (not shown) in which a chopper is not used in the light path, the reference signal is modulated by an electrical chopper at e.g. 1 KHz, to enable after common amplification of test and reference signals, separation out of the reference signal for gain control purposes. This enables slow variations in light source intensity to be compensated for. In a further arrangement, Fig.4 (not shown), a light chopper is not used and the test signal is chopped. The test to be carried out may be transmissivity or absorption of a substance in the measurement path 24, a reflex reflector 18 returning the beam to the photo-electric system. Alternatively reflectivity of an object may be measured.
