Title: Improvements in circuits for measuring short periods of time
IPC: G01S1/02
Filed: 1945-05-02
Abstract: 5 9 7 , 0 5 2 . Valve circuits; radiolocation. PLETTS, J. W. May 2, 1945, No. 11199. [Class 40 (v)] [Also in Group XXXVI] A pulse radar system comprises a time-base circuit wherein the sawtooth time base voltage is applied differentially with the output from a potentiometer to the deflecting plates of the cathode ray tube, the setting of the potentiometer indicating the range from which is received an echo signal appearing at the centre of the trace, and wherein the rate of change of time base voltage is controlled by an adjustable datum voltage which is also applied to the potentiometer so that the rate of change of time base voltage may be altered without upsetting the correlation between the potentiometer setting and range. A pulse waveform 25, which is synchronized with the exploring pulse, is applied to the suppressor grid of a pentode 20 which is normally cut off. At the instant of transmission the pentode conduits and, due to the Miller timebase circuit comprising condenser 22 and resistor 23, its anode voltage falls at a nearly constant rate, proportional to the " datum " voltage on line 24, the total amplitude of the sweep voltage being nearly equal to the " supply " voltage on line 26. The saw tooth waveform from the anode of the pentode 20 is fed to one X-plate 28 of a cathode ray tube, the other plate of which is connected to ground. The voltage of the plate 28 is initially that of the slider of potentiometer 32 and falls from this value by nearly the whole of the supply voltage at a constant rate. The potentiometer slider is set so that the received echo is displayed at the centre of the cathode ray tube screen, so that the echo time is equal to the time taken for the time base voltage to fall by the voltage at the potentiometer slider. Both the rate of change of the time base voltage and the potentiometer voltage are proportional to the datum voltage on line 24, and thus the switch 35 may be opened and closed without affecting the potentiometer setting corresponding to any particular echo time. With the switch closed, the time base voltage falls at a high rate, so that the trace on the cathode ray tube corresponds to only a short element of the total range, and even with the potentiometer set for maximum range, the echoes which can be received on the screen are from comparatively near objects. However with the switch open the voltage falls at a much lower rate, so that, although echoes appearing at the centre of the screen are, for the same potentiometer setting, from the same range as before, an echo from a considerably greater distance can be seen and its range estimated. Specification 582,170 is referred to.

Title: Method and apparatus for spinning fibrous material

Abstract: 1,133,710. Break-spinning method and apparatus. TSENTRALNY NAUCHNOISSLEDOVATELSKY INSTITUT IHHLOPCHATOBUMAZHNOI PROMYSHLENNOSTI. 15 March, 1966, No. 1124/66. Headings DID and D1F. In a method of break-spinning in which the fibres are separated, transported by an air-jet, and collected on a rotating take-up member and twisted into yarn, the fibres are subjected to the field from a corona forming electrode before they are collected. There is also provided apparatus comprising separating and spinning apparatus, wherein the former includes a nozzle with a corona-forming electrode and the latter a rotatable member spaced from the nozzle, the separating and spinning apparatus being connected in an electric circuit so that a potential difference can be established between the end of the nozzle and the rotatable member. In Fig. 1 fibrous material is fed beneath a plate 2 by a roller 1 to a separating roller 3 e.g. one covered with card-clothing. The fibres here separated are transported to a take-up member 11, which may be conical, rotating inside a chamber 13 with an outlet 14, the transportation being effected by a current of air generated by the rotation of the member and of the roller, assisted if desired by fan-blades 12 arranged below the member. As they leave the roller 3, the fibres pass through a nozzle 4 tapering towards its outlet so that the transporting aircurrent is accelerated. At the inlet and outlet of the nozzle are electrodes 7, 8 connected by a resistance coil or resistance layer 6: the upper electrode is connected to one pole of a high-voltage d.c. source, the disc 11 being connected to the other pole, the lower electrode 8 having a corona-forming electrode 9. As the fibres pass down the nozzle, they are acted upon by the air-current and the field inside the nozzle, the intensity of which increases towards the nozzle-outlet. The fibres thus undergo a parallelizing and straightening action which is completed when they reach the field arising from the d.c. corona. The spun yarn is drawn off by rollers 21, 22 and is wound up on a drum-driven package 26, 27 a break-detector 24 being provided. At the outlet from the disc 11 the yarn is gripped between the side of the outlet and a ball (20) Fig. 5, not shown. At the outlet 14 of the chamber, a regulating valve and a collector for un-spun fibres are provided.

[Class 80(ii)] [Also in Group XXXV] An electric motor and transmission unit for driving sewing machines &c. comprises a cylindrical housing 16. supporting a motor 10 on the shaft 11 on which is mounted a flywheel 12 having a friction ring 14, and a clutch mechanism having an axially movable element with opposite friction faces 38, 39 ;which selectively engages the flywheel ring 14 or a stationary braking friction ring 40 respectively. The clutch movable element is fixedly mounted on a stub shaft 26 axially slidable with its sleeve 31 within a fixed cylindrical journal' box 24. At the out- ,side of shaft 26 a belt pulley 28 is fixedly mounted, so that the clutch movable element, pulley 28, stub shaft 26 and a ballbearing assembly 25 are axially shiftable as a unit. The rotation of the : motor is never .interrupted whatever the position of the shaft 26. Fig. 2 shows how the device is supported to sewing machine table 43. The housing 16 is pivotally secured: to a bracket 45 having on one side a pair of laterally spaced arms 46-46. respectively fitted with pins 47-47 which project through apertured lugs 48-48 formed on the housing 16. At the other side of the bracket 45, a channel-shaped member 50 is pivotally secured at 49. The free end of the member 50 is telescoped within a second similarly shaped member 51 to which it is secured by a bolt 53. The free end of the member 51 has slots 54-54 through which extends a pin 55 which also passes through lugs formed on the housing 16 at the opposite side to where the first lugs 48-48 are formed. A member 58 is also pivotally connected with the pin 55 and it is held in engaging position with the member 51 by a coil spring embracing the pin 55. When the member 58 is pressed, the parts are released fromtheir interlocked engagement enabling the motor to swing about pins 47- 47 and thus permit the removal of the pulley belt without disturbing the effective length of the link members 50, 51.

IPC: D05C7/06
Abstract: 115,650. Thompson, W. P., (Union Special Machine Co.). Oct. 28, 1916. Fringing-machines.-A sewing-machine having an overedge stitch-forming mechanism is provided with means to engage at intervals either the needle or the looper thread to form a series of loops which project beyond and in the plane of the fabric sewed to form a purl or picot edging. The machine comprises, as usual, a needle 5, Fig. 2, loop-spreader 11, threaded looper 20, and feed-dog 26, all operated from a main shaft 10. The picot loops are formed by a hook 30 adjustably clamped in a head 31 carried by a bar 32, which is mounted to reciprocate in a sleeve 34. This sleeve is pivoted at 35 to a bracket 36, and is provided with an arm 37 pivoted at 38 to a strap 39 surrounding an eccentric 40, which is adjustably secured to a spur wheel 41 in gear with a pinion 43 on the shaft 10. The end of the strap 39 is slotted to receive adjustably a pin 44, which is engaged by a cross-head 46 on the bar 32. With this construction, the hook 30 is moved forwards, then downwards, then slightly backward, then upwards, and then again forwards, while the timing is such that it engages a loop n' of the needle thread at every third stitch. The hook holds the loop after it has been released by the spreader 11 and until both the spreader and the looper 20 have been retracted to set the stitch, with the result that the picot loops are of uniform size. In a modified construction, the spreader 11 is replaced by a threaded looper, the thread of which is engaged by the hook 30 to form the picot loops.
