Title: Electrical transducer
IPC: G01D5/20
Filed: 1964-01-09
Abstract: 1,001,395. Electro - selective signalling. SHEFFIELD CORPORATION. Jan. 9, 1964 [Jan. 10, 1963], No. 1064/64. Heading G4H. [Also in Division G1] In a linear dimension measuring transducer a differential capacitor is connected in a bridge network to a voltage divider, and an element of the capacitor is linearly movable so varying the ratio of the capacitances thereof, and the amount of adjustment of the voltage divider necessary to balance or null the bridge is taken as a measure of the distance moved by the capacitor element. The voltage divider may be preset at a desired distance value and the moving part of the capacitor driven by a motor, energized by the amplified unbalance voltage, until at balance or null position the motor will stop, the capacitor element having been moved the desired distance. Transducer construction.-The capacitor comprises a hollow metal cylindrical pick-off 16 (Figs. 2, 4) and conductor bar members 17, 18 movable along the cylinder axis by a motor 45, and connected mechanically in end abutting relationship through an insulating disc. The cylinder is insulatingly supported in a metal housing 14. Circuitry.-An A.C. source e.g. 125 v. at 1000 c.p.s. from a transformer 52 is connected to the bars 17, 18 and the cylindrical pick-off has an output connection 33 to an amplifier 34 the output voltage of which together with a reference voltage, from a voltage divider comprising a bank of auto transformers, is fed to an amplifying and combining device 55 and thence to a phase-sensitive detector 57. The amplified output of the detector 57 is used to run the motor 45 which thereby varies the output of the capacitor. When the latter voltage exactly balances or nulls the reference voltage the motor stops and the distance moved by the capacitor bars will correspond to the setting of the voltage divider which may be calibrated in linear measure units. Alternatively the capacitor bars may be manually displaced and the amount of displacement determined by nulling the signal output therefrom by adjustment of the divider until an indicator 58 reads zero.

Filed: 1935-01-16
Abstract: 455,372. Automatic guns. BIRKIGT, M., Rue du Capitaine Guynemer, Bois-Colombes, Seine, France. Jan. 16, 1935, No. 1519. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 2, 1936]. [Class 92 (ii)] Relates to gas - operated guns in which the breech block 6, Fig. 3, and strikerpost 7 are controlled by a common return spring 5 which serves both to close the breech and move the striker - post a further distance forward to fire the gun. According to the invention, the striker-post 7 is, by the action of the gas piston 23, Fig. 1, on rods 27, first moved relatively to the breech block to release a locking latch 13, pivoted to the block. The latch engages a notch 15 in the gun casing and also serves, by engagement with a recess x in the striker-post, to lock the parts 6, 7 together throughout the opening and closing movements of the block and until the latch re-engages the notch 15 when the post is released for firing. The striker-post is formed by lateral arms joined by a transverse pin 9 which passes through a slot 12 in the breech block. On firing, the post moves a short distance rearwards and the latch, which engages the casing by an incline 15, can rise to engage the incline 16 in the recess x thus locking the parts 6, 7 together whilst the latch rides on the surface 18 during the rearward and forward movements of the breech block 6. When the breech block is in closed position, the latch can fall into engagement with the incline 15 and the post is then free to move forwards to fire the gun.

In carrying out the method of Parent Specification according to which a sample is heated under reduced pressure and the temperature is controlled so that the rate of evolution or absorption of gas is kept constant, the temperature being plotted against the volume of gas evolved or absorbed, Fig. 2 (not shown), the temperature of the sample 44 in its evacuated container 43 is varied by moving the container into a heating chamber 41 to a varying depth or by moving the container into and out of the heating chamber and varying the proportion of time spent in the chamber, e.g. by varying the amplitude of the movement. As shown, the container 43 extends radially from a shaft 47 positioned or oscillated by a motor 49. The latter is controlled, by a device which senses the pressure in the container, to keep that pressure constant so that the rate of evolution of gas balances the rate at which the vacuum pump connected to the container removes gas therefrom.

Title: Improvements in artificial filament spinning machines
IPC: D02J1/22
Filed: 1945-01-24
Abstract: <PICT:0584719/IV/1> <PICT:0584719/IV/2> <PICT:0584719/IV/3> A machine for making artificial filaments comprises a spinning bath compartment extending longitudinally of the machine, one or more spinning stations each comprising a filament-collecting device and a spinneret adapted to be immersed in the bath, and means for withdrawing the filaments from the spinneret through the bath obliquely to its length and for conducting them to the collecting device, comprising a plurality of rotary members, each of which is arranged with its axis of rotation substantially at right angles to the directions of approach and departure of the filaments with respect thereto.  One of the rotary members may be arranged to withdraw the filaments from the spinneret through the bath obliquely to its length and another rotary member may be arranged to receive the filaments from the first member and to direct them on their way to the collecting device.  As shown in Fig. 3, a bundle of filaments 2 proceeds obliquely from spinneret 3 to a drawing rotor 4 about which it is wrapped a few times before proceeding to rotor 6.  The filaments then pass vertically downward through funnel guide 8 to a further treatment station or to a collecting device.  The drawing and guiding members are arranged so that the courses of the filaments approaching and departing from each of the rollers are substantially coplanar with the course of travel about the respective roller and substantially at right angles to the axis of the roller.  Lapping is effected by means of a guide roller 5 set at a slight angle to the axis of the drawing member as shown in Fig. 3, the angle being small so that no slippage occurs.  Where the total denier of the bundle of filaments is very large or where it is desired to displace the successive laps, a guiding roller 9 as shown in Fig. 4, is used, this roller being about the same size as the drawing roller 10 in order that substantially coplanar relation may hold. Alternatively, the guide means shown in Fig. 7 may be used. The arrangement of roller may be adapted for stretching during spinning, or the filaments may be released between rotors 4 and 6. The filaments may be treated with liquids or vapours while passing from one rotor to the next.
