Title: Improvements in or relating to echo sounding apparatus
Inventor: WELSH ALFRED WILLIS
IPC: H01H36/00
Filed: 1963-11-07
Abstract: 1,012,104. Echo sounders. S. SMITH & SONS (ENGLAND) Ltd. Nov. 7, 1963, No. 43938/63. Heading H4D. In an acoustic echo sounder in which received echo signals are fed to a moving stylus 6 to produce on a recording sheet 18 a mark, which when read against a scale 13, gives the range of the object producing the echo, adjustment of the position of the scale relative to sheet 18 by manual operation of knob 20 to accommodate different ranges also operates to alter the time interval between the instant of transmission of a pulse of acoustic energy by the transmitter - receiver transducer 15 and the instant that the stylus (carried by a continuously rotating endless belt 3 surrounding sheet 18) engages the recording sheet. This is achieved by adjustment (under control of the knob 20) of the angular position of a dry-reed switch 9 closure of which by means of a magnet 7 passing adjacent thereto initiates the production of a pulse by the transmitter-receiver 14. The gear-wheel 5 carrying magnet 7 effects one revolution for each complete revolution of the belt 3 and the motor (not shown) which drives shaft 1 may be arranged to operate at different speeds, the scale 13 being provided with different range calibrations corresponding to each speed.

Title: Improvements in electromagnetically operable fluid-flow control valves
IPC: F16K31/06
Filed: 1965-10-19
Abstract: 1,114,555. Valves. REGIE NATIONALE DES USINES RENAULT. 19 Oct, 1965 [20 Oct., 1964; 8 Oct., 1965], No. 44327/65. Heading F2V. In an electrically operated valve, energization of a winding 3 causes a loose ball 6 to engage a seat 9 provided in an inlet passage 4 formed in the core 2, the seat being arranged to hold the ball spaced from the end of the core to provide an air gap 11 to assist unseating of the ball on de-energization. When the ball is unseated, fluid flows to the outlet via helical grooves 12 which cause the ball to be rotated. A threearmed threaded plug 14 having passages 15 holds the ball captive. In the embodiment of Figs. 3 and 4 (not shown), the casing (21), core (22), cover (26) and ball (30) are made of magnetic material and the coil (24) is formed with radial arms (35, 36) having bushed holes into which the wires are welded. In Fig. 5 (not shown), the loose ball (30) of Figs. 3 and 4 cooperates with a smaller ball (46) movable in a seat member (47) to control flow through an orifice (48) in the latter, the seat member being located in the inlet passage and having helical grooves (49) to cause rotation of ball (46). The seat member of the above-described valves is usually non-magnetic, but in cases where the core or the ball is of a material having high residual flux density and low coercive field, the seat may be magnetic. In these latter cases a small reverse current is required to enable the fluid to unseat the valve.

Abstract: 1,196,002. Television, radio frequency systems. BRITISH BROADCASTING CORP. 7 Aug., 1968 [29 Sept., 1967], No. 44545/67. Headings H4F and H4L. In order to reduce distortion of the "back porch" of a television waveform, the amplitude near the end of the back porch is sampled and held by a time-constant circuit incorporated in a video amplifier and gate 15. The purpose of the gate is to remove any additional information, for example pulse-code modulation, occurring in the line synchronizing intervals. The timeconstant circuit is actuated by clamp pulses (b), occurring near the end of the back porch interval, from a generator 16 which is synchronized by pulses from a synch-pulse separator 17 which extracts line synchronizing pulses from the input waveform (a). Separator 17 also synchronizes a pulse generator 18 which generates pulses extending over nearly all the back porch interval, which are applied to a gate 19 in order to pass, for the duration of the last mentioned pulses, a signal corresponding to the level stored in the time constant circuit. In the case of colour television the colour bursts are preserved using a parallel rejector circuit 20 tuned to the burst, frequency.

Abstract: 1,165,436. Vehicle braking systems. ALFRED TEVES G.m.b.H. 5 Oct., 1967 [20 Jan., 1967], No. 45532/67. Heading F2F. A servo-braking system uses pressure liquid obtained from a pump in the vehicle (e.g. the lubricating oil pump or that of the automatic transmission) acting on a control piston within a bore in a booster piston which operates a third (master cylinder) piston, there being a slidable sleeve around the control piston which closes the connection between the pump and the booster piston when the brakes are released. In the Figure the brake pedal acts on a member 3 which drives a control piston 4 to move its face 25 away from the face 26 of a control sleeve 5 into the position shown. Liquid pressure from a pump 13 and reservoir 15 is then admitted into chamber 23 and drives a booster piston 1 to the left, flexing a diaphragm 9 against a spring 7. Movement of the booster piston 1 is transmitted through a semi-rigid member 8 to a rod 6 coupled to the piston 22 of a master cylinder 21. When the pedal is released, the faces 25 and 26 abut once more, and the liquid pressure acts on the other end 24 of the sleeve 5, which is larger than the face 25, to drive it to the right and disengage it from a seal 10. Pressure is then applied to the annular space between the sleeve 5 and control piston 4 and drives the latter back to its original position.
