Patent GB-834666-A (GB)
Abstract: 834,666. Liquid-ejector valves for gas systems. WILKERSON, D. E'. June 7, 1956, No. 17698/56. Class 64(2) [Also in Group XXIX] In a valve controlling air flow and having means for expelling moisture &c. a sleeve 16, Fig. 1, which depends from the valve housing cover 11 accommodates a spring-loaded piston 17 that has a pressure equalizing passage 19 therethrough; an annular channel 20 around the sleeve communicates with an inlet 21, the sleeve forming a baffle for the incoming air, whilst the outlet connection 22 is located intermediate the cover 11 and the piston when the latter is in the inactive position shown. A dished partition 25, which is in the lower part of the casing and defines one wall of a drain sump 13, has a tubular stem 28 with a castellated top 33, Fig. 3, and radial bores 34, 35 and 36, all of which open into an axial bore 32 in the stem 28 whilst the bores 35 and 36 are associated with the sump 13. The bores 35 are controlled by a valve 37 with spaced packing rings 38, 39, which valve is attached to the piston through a hemispherical head 41 and a socket 42. A filter 27 is held between the partition 25 and the sleeve 16. When air is drawn through the outlet 22, the pressure in chamber 15 above the piston 17 is reduced and the inlet air pressure in chamber 14 beneath the piston lifts the latter until it uncovers the outlet 22. The valve 37 is also lifted whereupon the ring 38 rises beyond the bores 36, hence breaking the connection between chamber 14 and the sump 13 via bores 32, 34 and 36; continued movement of the valve lifts the ring 39 above the bores 35 and opens the sump 13 to atmosphere via the bore 32 for the expulsion under pressure of moisture or other matter therefrom. Upon cessation of the flow of air through the outlet 22 the piston 17 and valve 37 is returned to the inactive position.

Patent GB-2145712-A (GB)
Title: Process for producing purified brominated aromatic compounds
Inventor: AYRES JAMES T
IPC: C07C41/22
Filed: 1984-02-29
Abstract: Highly purified brominated aromatic compounds such as decabromodiphenyl ether, pentabromophenol, and the like may be obtained by grinding the crude brominated product to provide particles predominantly less than about 20 microns in diameter and thereafter heating the crude ground brominated product for a time and at a temperature in order to effect substantial removal of the bromine and hydrogen bromine impurities therefrom. Optionally, the product may be ground a second time after the heating step to optimize product particle size and liberate residual impurities. The foregoing procedure is especially effective where the brominated compound is a thermally stable solid under the conditions of treatment and is substantially free from impurities containing aliphatic and alicyclic hydrocarbon groups.
Patent GB-2157519-A (GB)
Title: A sample and hold circuit
Inventor: SABET COOROSH
IPC: G11C27/02
Filed: 1984-04-14
Abstract: A sample and hold circuit consists of three gates (1, 2, 5) such as Metal Oxide Silicon Field Effect Transistors or high speed diode bridges, two high input impedance buffers (4, 7) and two capacitors (3, 6) connected in cascade. A pulse conditioner/delay line provides three pulses A, B and C with predetermined delays between pulses A and B. In one embodiment gates 1 and 5 which are normally closed are opened on the simultaneous application of pulses A and C respectively. Gate 2 which is normally open is closed on the application of pulse B after a delay of  DELTA t. The time delay DELTA t between opening gate 1 and closing gate 2 allows a sample of analogue input signal to pass through and be temporarily stored in capacitor 3. Meanwhile gate 3 allows the above-mentioned analogue sample to be stored for a sufficiently longer time in capacitor 6 in order to be digitized by the subsequent analogue to digital converter. Therefore the resolution of the present sample and hold circuit is substantially determined by the delay  DELTA t which can be as short as required. <IMAGE>

Title: Direction finding arrangement
Inventor: BRIERLEY WILLIAM EDWARD
IPC: G01S3/808
Filed: 1984-10-25
Abstract: An acoustic direction finding arrangement has three microphones A,B,C, connected as three sets of two. The relative time of reception of sound at each microphone is determined by adjusting a variable delay device 14, and the delay is obtained in terms of a clock frequency value Fo, from which the direction of the sonic source can be determined. A phase sensitive rectifier 16 produces a signal representative of the phase difference between the two signals A,B and controls the clock frequency VCO 17 to vary the delay imparted by means 14 so that the signals arrive at the rectifier 16 in synchronism, i.e. the phase difference is eliminated. The microphones A,B,C may be arranged as a three-dimensional array. <IMAGE>

Title: Treatment of cementitious products
Inventor: ATKINSON ALAN WILLIAM
IPC: C04B28/06
Filed: 1984-12-15
Abstract: Shaped products (e.g. sheets) comprising a matrix of water-insolubilised organic polymeric material (such as hydrolysed vinyl acetate polymer) filled with set hydraulic cement, as described for example in European Patent Publication 55 035 (ICI), have an unusually high flexural strength, above 40 MPa, but this falls considerably when the products are heated above about 250 DEG C. By the invention, the extent to which flexural strength of such products is lost when they are heated is reduced, by first heating to burn out the organic polymeric material, and then bringing the product into contact with water to form a set cement in the interstices left by the burnt-out material.

Title: Improvements in and relating to cleaning of gases
Inventor: ALDERTON GEOFFREY WALTER
IPC: B04B5/12
Filed: 1985-06-24
Abstract: For cleaning a gas flow, a saturated stream of gas is introduced into a centrifuge. Initially the gas is directed radially inwardly towards the axis of the centrifuge from an annular inlet at one end of the rotor of the centrifuge. Resulting adiabatic cooling causes droplets of moisture to form within the rotor and the droplets are attracted by centrifugal action to the wall of the rotor. In moving towards the wall the droplets collect particles and the like in the gas flow. Clean gas exits at one end of the rotor and the droplets carrying the particles flow along the wall and out of the rotor.
