Title: Improvements in or relating to control means for single-stroke pressure-responsive devices
Inventor: HOLM HANS FESER
IPC: F15B11/08
Filed: 1953-04-15
Abstract: 725,011. Pneumatic single-stroke apparatus. SMALLPIECE, Ltd. April 15, 1953, No. 10261/53. Class 8 (2). A piston 13 is moved from one to the other of its extreme positions in a cylinder 12 by gas pressure supplied through a duct 7 of a central valve A and one or other of ducts 10, 11 according to the position of connected valve pistons 4, 5 which is determined by pressure supplied from a compressed gas duct 30 through a 3-way impulse valve 28 normally open to atmosphere, a duct 26, a bore 19 of a control valve B having a piston 23 and one or other of ducts 16, 17 leading to chambers 14, 15 respectively at the ends of the casing 1 of the valve A according to the position of the piston 23 which is actuated by pressure built up in one or other of bores 20, 21 connected by ducts 31, 32 to the chambers 14, 15. In the position shown the piston 13 has completed its stroke to the left and the gas pressure built up on the right thereof has displaced a piston 25 in the bore 21 and hence the piston 23 connected thereto to the left so that on opening the valve 28 compressed gas from duct 30 traverses the bore 19 and duct 17 to the chamber 15 to displace a piston 6 and pistons 4, 5, 3 connected therewith so as to open the duct 10 to the supply duct 7 and connect the duct 11 to an exhaust duct 9. The valve 28 is of the 3-way type biased so as to connect the duct 26 with an opening 29 to atmosphere and if after pressing the knob 27 to connect ducts 30 and 26 and so initiate a stroke of the piston 13 the knob is then released before the completion of the piston stroke no displacement of the valve pistons 23, 24, 25 occurs since the necessary pressure build up can only occur at the end of the working stroke.

Title: Improvements in or relating to hydraulic dampers
IPC: B64C27/00
Filed: 1953-04-15
Abstract: 729,801. Rotary wing aircraft. UNITED AIRCRAFT CORPORATION. April 15, 1953 [May 3, 1952], No. 10287/53. Class 4. [Also in Group XXXII] Lag-lead movements of the blade of a helicopter relative to its rotor head, are damped by a dash pot 38 (see Group XXXII), which has a greater damping effect when the helicopter is on the ground, than during normal flight. The dashpot 38 incorporates a time delay valve which causes a further restriction in flow, after a time; which is equal to the period of the lag-lead vibrations of the blade during flight. When the aircraft is on the ground, the period of the laglead vibrations is 3¢ times longer than the period of the vibrations occurring during flight. Thus the further restriction operates for a substantial amount of the dashpot stroke. The blade (not shown) is carried by a hinge 42 having a yoke 45. A pin 50 rigid with the yoke 45 is journaled in a pin 54, itself journaled in upper and lower plates 32 of the rotor head. The pin 50 carries an extension 52 on which a yoke 52<SP>1</SP> is journaled. The cylinder 72 of the dashpot is pivotally mounted to the yoke 52<SP>1</SP>, and the piston rod of the dashpot is pivotally connected at 96 to the rotor head. Specification 641,076 is referred to.

Title: Apparatus for remotely indicating the level of liquid in a tank
Inventor: MOREAU HERVE
IPC: G01F23/72
Filed: 1967-03-03
Abstract: 1,131,299. Measuring liquid level electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 3, 1967 [March 3, 1966], No.10301/67. Heading G1N. The level of liquid in a sealed tank 2, Fig. 1, is indicated using a float 8 which comprises an annular magnet 9, housed in the float which is slidable along a non-magnetic steel tube 3, and an associated magnetic core 7 suspended on a stainless steel wire 5 from a disc 6. Between the disc and the core, the wire passes round a pulley 12 mounted on one end of a lever arm 13, the other end of which carries the core 16 of a differential transformer 17, which is thus positioned according to the wire tension. A counterweight 31 is arranged so that for a predetermined "equilibrium" tension, the core 16 is positioned centrally in the transformer 17. As the liquid level changes, the tension in the wire 5 and correspondingly the position of the core 16 will change accordingly due to the change in the Archimidean thrust on the float 8. A signal is thus transmitted from the transformer 17 to a two phase motor 21 which rotates the disc 6, via shaft 41, to re-position the float at the surface of the liquid. The amount of rotation of the shaft, indicating the change in liquid level, may be measured electrically, by mechanically connecting a three turn linear potentiometer (45), Fig. 2 (not shown), to the shaft 41, or pneumatically by controlling the pressure in a power relay 33 according to the rotation of the shaft. Alternatively a digital indication of the rotation of the shaft 41 may be obtained from a step-by-step motor (53), Fig. 3 (not shown), driven by pulses from the motor 21 and a photo-electric cell (56).

Abstract: 287,731. Brandwood, J. April 19, 1927. Hanks, treating.-Relates to a method of, and apparatus for, treating artificial silk skeins with liquor and subsequently removing superfluous moisture. wherein the skein is given two movements, one circular as a whole about its centre and the other in the direction of the skein threads, in the liquor, and then, out of contact with the liquor, the circular movement only is continued, at increased speed. The hanks are carried between pairs of rollers 57 on a series of removable holders which are inserted in V-bearings 7, 10 in a tank 5. The holders are simultaneously rotated, neighbouring holders in opposite directions, by an endless cord 16 passing under and over pulleys 15. Motion from the driving-shaft 38 is transmitted during the liquid treatment through reducing gear 37 and a reversing clutch 31 to a shaft 24 of one of the pulleys 15; but during the centrifugal drying, the clutch 31 is placed in neutral position and a clutch 39 is engaged to drive at a higher speed a shaft 42 on another pulley 15. The hank-bearing rollers, comprising a number of rods or tubes 57, are rotated on their own axes during the liquid treatment only, by engagement of pinions 59 with a pinion 60 rendered stationary by being locked by an arm 63 engaging a pin 62 on the pinion. The pinion 60 however is released to run idly during the drying operation. One of the rollers 57 is adjustable on the holder and is moved inwards along slots 49, after release of a screw 52 and disengagement of pinion 60 by axial movement, in placing hanks on, or removing them from, the holder.

Abstract: 625,486. Radio signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 8, 1946, No. 10789. Convention date, April 9, 1945. [Class 40 (v)] At a radio relay station handling signals consisting of a frequency-modulated subcarrier frequency modulated on to the main carrier, additional channels are modulated on to the signal by extracting the modulated subcarrier and beating it with an oscillator modulated by the additional channels. The in- ' coming 3000 mc/s. signal at the relay station shown in Fig. 1 are frequency-modulated by a 1 mc/s. sub-carrier which in turn is frequencymodulated to the extent of Œ200 kc/s. by a group of 6 speech channels formed by modulating each channel on to separate local oscillators and selecting the lower sidebands. This signal which is received on aerial 2 is amplified at an intermediate frequency and detected to produce the modulated sub-carrier which is passed via lead 14 to mixer 28. Here it is combined with an 11 mc/s. signal from beat oscillator 26 to produce a modulated 12 mc/s. signal which is passed to mixer 36 where it is combined with a 13 mc/s. signal from beat oscillator 50 to reproduce the 1 mc/s. modulated sub-carrier. This is finally amplified at 38 and modulated on to a 3010 mc/s. carrier for retransmission. The additional modulation is effected by modulating the 11 mc/s. beat oscillator 26 by means of reactor valve 68 which is controlled through pre-emphasis network PEN by the local channel assembling unit 72. In a similar manner further modulation may be added by means of reactor valve 56 connected to the second beat oscillator 50. Unit 22 is provided to monitor some of the channels of the received signal. In an alternative arrangement (Fig. 2, not shown), the two beat oscillators are modulated in push-pull by one signal to produce twice the deviation. Specification 625,488 is referred to.
