Title: Improvements in thermionic amplifiers
IPC: H03F1/04
Filed: 1938-07-06
Abstract: 516,745. Valve amplifying circuits. SNEATH, O. B. July 6, 1938, No. 20042. [Class 40 (v)] In an audio-frequency amplifier, a rectifier in the grid circuit is arranged to reduce, as the signal becomes weaker, the biasing-voltage, and so economize in anode current. In Fig. 4, the cathode load, which may be a resistance or the normal output load, is connected across A, B. The grid is negatively biased by the cathode load so that only a small anode current flows, but when a signal is applied the rectifier N produces a voltage which reduces the bias to a normal working value. In modifications, Figs. 1 and 2 (not shown), the output load may be connected in the anode circuit, or in series with a variable resistance in the cathode circuit. A voltage from the cathode load may provide either negative feed-back, or by rectification an automatic-volume-control voltage. An automatic volume control voltage may be obtained as shown in Fig. 4 at Y from the potential divider R8, H9 and the smoothing circuit C3, R10, C4, the voltage of the H.T. negative with respect to cathode and earth varying with the volume.

Patent GB-634333-A (GB)
Title: Improvement in wringers
IPC: D06F45/18
Filed: 1947-07-29
Abstract: 634,333. Wringers. LOVELL MANUFACTURING CO. July 29, 1947, No. 20487. Convention date, Aug. 7, 1946. [Class 138 (ii)] In a wringer having a head mounted for swinging movement on a wringer post and yieldably indexed in a plurality of angular positions, and having roller drive gearing biassed to neutral by spring and torque action, the gearing is movable by manual means to driving and neutral positions and is held in the driving position by latch means, the movement of the wringer from an indexed-position operating latch-releasing means to move the gearing to a neutral position independently of the manual means. The lower roller 19 is coupled through a universal joint 20 to a crown-wheel 15 which is in constant mesh with two pinions 21, 22, loosely mounted on a shaft 23. Grooves 30 in each pinion are engaged by a carrier 28 through which clutch teeth 31 on the pinions may be alternatively engaged with pins 32 on the shaft 23. The carrier 28 is biassed to a neutral position by a spring 33 and is moved to engage one or other of the clutches by a crank-pin 53 on a shaft 52 which is connected to a control handle 49 through a lost-motion connection comprising a set-screw 51 engaging a slot 50. The carrier 28 is latched in the driving position by a bell-crank 38, a projection 40 on which can engage either the upper edge 42 or a slot 43 of the carrier. A spring 44 keeps the bell-crank in engagement with a slidable latch-plate 54 and a pin 56 on the latch-plate in engagement with a cam 47 carried by the handle 49. In the neutral position of the carrier 28, the pin 56 seats in a detent 57 of the cam and, in either driving position, on shoulders 58 which permit the projection 40 to engage the carrier 28. Movement of the handle 49 from the driving to the neutral position first cams the pin on to a raised surface 59 of the cam to release the latch and then the lost-motion connection engages the shaft 52 to move the carrier 28. To stop the drive in the event of the operator's fingers being trapped, the roller frames 1, 2 are pivoted to the head 3 by bolts 7, 10, a pull or push on the rollers causing an extension 11 of the top frame 2 to engage one or other of a pair of spring-loaded bell-cranks 60, 61 either of which can unlatch the carrier 28 by moving the bell-crank 38, the driving torque and the spring 33 then operating to unlatch the drive. The wringer is indexed in any one of a plurality of angular positions by a spring-loaded index pin 72, a tapered end 71 of which engages one of a number of recesses 69. Movement of the wringer head cams the pin out of the recess and, since the head is prevented from rising by a bracket 68, the pin is raised against its spring 74 and raises a spring-loaded slidable lever 76, the upper end of which has a pin-and-slot connection with the bell-crank 38, which is thus raised to unlatch the carrier 28 and so stop the roller-drive.

Title: Improvements in or relating to centering mechanism for aircraft wheel mountings having castoring or equivalent motion
IPC: B64C25/22
Filed: 1944-10-24
Abstract: 585,896. Retractable wheels for aircraft. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. Oct. 24, 1944, No. 20651. [Class 4] A castoring retractable aircraft tail-wheel has means for aligning the wheel with the plane of retraction before or during retraction by means of a hydraulic motor other than that used for retraction. The wheel is mounted, by shock-absorbing means contained in the lower part of the housing 10, on a cylinder 16 rotatably mounted in the housing 10 which is pivoted at 11 to the aircraft to permit retraction by means or a double-acting hydraulic jack connected between the lower part of the housing 10 and the aircraft framework. A recess in the upper part of a plug 24 secured to cylinder 16 receives a tubular cam member 57 which has an oblique cam surface 58 engaged by a roller 59 secured by a pin 60, sliding in longitudinal slots 62, 63 in the fixed stem 54, to a piston 68 sliding, but not rotatable, in the cylinder liner 55 of the stem 54. A spring 64 supported by a thrust ring 66 bears on a flange member 65 mounted on a sleeve 61 secured to the pin 60 and thus provides, by the 'reaction between cam 57 and roller 59, a force centring the plug 24 and the wheel during taxying. Chamber 70 is connected by a conduit 71 to the same source of pressure as the jack for retraction, so that operation of the retracting valve supplies hydraulic pressure which supplements the effect of the spring 64 to centre the wheel. In a modification, upward movement of the piston 68 closes a valve in the retraction circuit so that retraction is impossible until the wheel is centred while a non-return byepass valve is provided, permitting the undercarriage to be lowered independently of the position of the wheel.

Abstract: 900,247. Nuclear reactors. PLESSEY CO. Ltd. June 10, 1960 [June 19, 1959], No. 21177/59. Class 39 (4). Apparatus for detecting fission products in a fluid carrier medium comprises means for transferring the gaseous fission products from the carrier medium to a carrier gas phase, means for electrostatically precipitating from the carrier gas phase the solid radioactive daughters of the gaseous fission products, and means for transferring the precipitated daughter products to a second fluid carrier medium and transferring them to a zone remote from the carrier gas phase for measuring the radioactivity. In the apparatus shown in Fig. 1, sample water which may contain fission products is fed under pressure to a chamber 9 and passes through a porous sintered stainless steel plate 6. Clean water is fed under pressure to an electrically insulated chamber 15 and passes through a porous stainless steel plate 12, and an electric field is maintained between plates 6 and 12. If the sample water contains the gaseous fission products Krypton and Xenon these pass from the water, as it emerges from plate 6, into the gas between plates 6 and 12; some of the Krypton and Xenon will then decay into charged Rubidium and Caesium ions which will be attracted to plate 12 by the electric field and there dissolve in the clean water emerging from the plate which is collected in chamber 24. The water from chamber 24 is fed to a radiation counter and a delay tank before being returned to chamber 15. Gas may be passed through the apparatus continuously or may be stagnant during the monitory cycle and purged between cycles ; the gas may circulate through a delay tank, a heater being provided in a gas duct to cause a convection circulation.
