Title: Viscosity responsive fluid flow control valve
IPC: F15B21/044
Filed: 1963-03-19
Abstract: 966,358. Fluid-pressure servomotor systems. T. F. LEWIS. March 19, 1963 [March 28, 1962], No.10903/63. Heading G3P. [Also in Division F2] A valve arrangement 10 has an inlet port 16 connected to an hydraulic pump and an outlet port 17 open to a reservoir. When the hydraulic system is idle, gravity pressure from the reservoir traverses a passage 21 and urges a ball 27 on to a seat 23 of plastic material e.g. P.T.F.E. in the inlet 16. When the system becomes operative the accumulated air at the inlet 16 firstly urges the ball 27 on to a seat 26 in an outer piston 25 and then presses both members 25, 27 against a spring 43 until the ball 27 abuts a stop 34 on an inner piston 30; the outer piston 25 continues to move until the air can flow around the ball 27 to the outlet 17 through the passage 21 and is permitted to escape at the reservoir. A by-pass route for the air is also formed by a channel 50 in the outer piston, holes 40 in the inner piston opening 37 around a spring-loaded tube 35 in the main piston, and port 51 in the latter leading to the passage 21. An auxiliary ball 36 is associated with the outer end of the tube 35. After most of the air has been removed oil flows through the channel 50 and port 51 urges the ball 36 on to a seat 36a in the inner piston so closing the by-pass route whereupon the pressure builds up behind the outer piston 25 which moves leftwards until the seat 26 engages the ball 27. Air bubbles bleed around the ball 27 through the seat 26 which does not form a perfect seal but is such as to prevent the flow of heavier fluid.

Title: Improvements relating to acoustic detector arrays
Inventor: CALLARD LINDSAY
IPC: G01S15/89
Filed: 1969-02-28
Abstract: 1,244,551. Piezoresistive devices. BRITISH AIRCRAFT CORP. Ltd. 27 Feb., 1970 [28 Feb., 1969], No. 10903/69. Heading H1K. [Also in Division H4] Each element of an electroacoustic array for use in recording sound-field patterns comprises a layer 16 of piezoresistive material sandwiched between crossed conductors 7, 8, one of which forms an ohmic contact with the layer 16, the other forming a rectifying contact therewith. The conductors 7, 8 are respectively members of one of two sets of parallel conductors, one element of the array being arranged at each intersection of the two sets. The layer 16 may be of zinc sulphide, zinc oxide, titanium oxide or cadmium sulphide, and for the last-mentioned material the ohmic contact may be of Ga or In, the rectifying contact being of Au or Pt. The conductor strips and piezoresistive layers may be formed by vacuum deposition, either through a mask or using selective etching, on to a substrate 2 having a thickness equal to a multiple of #/4 for the acoustic waves being detected. Alternatively, the substrate 2 may be of arbitrary thickness but mounted on a highly sound-absorbing support, e.g. of tungstenloaded " Araldite " (Registered Trade Mark). For use in acoustical holography for underwater viewing the array is mounted in a watertight manner. The piezoresistive layer 16 of each element discharges the self-capacitance of the element during the time interval between successive rechargings as the elements of the array are all scanned in turn by voltages applied to the rows and columns of the array. The voltage required to recharge the element each time, and hence the output signal from the element, is dependent upon the integrated sound intensity incident upon the element between successive screws. The array detects sound waves reflected or diffracted from an object in the presence of an underwater ultrasonic generator. The output from the array is displayed on a C.R.O., where it is photographed, the photograph serving as a hologram. The original object is then reconstructed by illuminating a reduced transparency of the photograph with converging laser light.
