Patent GB-639273-A (GB)
Title: Improvements relating to methods of preparing dielectric materials
IPC: C04B35/46
Filed: 1947-10-21
Abstract: Dielectric material is prepared by heating uncompacted, finely divided titanium dioxide, the crystal structure of which does not correspond with that of rutile, at a temperature above 1200 DEG  C., preferably up to 1400 DEG  C. in the presence of 0.1-0.3 per cent aluminium oxide until the crystals possess an average size of 1-2 microns.  Pigment grade anatase titanium dioxide is suitably used as the starting material.  Salts, e.g. the sulphate, nitrate and acetate, decomposing at the reaction temperature may be used as the source of the alumina; suitably, aluminium sulphate may be added to an aqueous slurry of titanium oxide, which is then brought to a pH of 6-7 with ammonia dewatered and dried prior to heating at 1250 DEG  C. for 6-12 hours.

Title: Improvements in inertia operated electric switches
Inventor: GRIFFITHS RUPERT
IPC: H01H35/14
Filed: 1955-10-04
Abstract: 826,735. Inertia switches. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. Jan. 4, 1957 [Oct. 4, 1955], No. 28198/55. Class 38 (5). In an inertia-operated switch having a member controlling the state of operation of at least one pair of contacts, a movement of the inertia slug in one direction causes a movement of the controlling member in the opposite direction to produce a change of state of operation of the contacts. Fig. 3 shows a changeover switch for a missile in which the inertia slug 10 is urged into the position shown by a spring 13 and carries a bow spring 12c. The ends of the bow spring are supported by the free ends of U-shaped resilient arms 12b forming part of a yoke 12a. Under static conditions the slug is in the position shown and the yoke 12a bridges contacts 15 (not shown) mounted on a plate 19. A predetermined acceleration causes the slug to move to the right against the spring 13 thus making the bow spring 12c snap over and move the yoke 12a to the left to open contacts 15 and bridge contacts 16 (not shown) mounted on the plate 11b. Deceleration causes the switch to revert to its original position. An anti-vibration damper member 10a with limited sliding movement is fitted within the slug 10.

Title: Pressure control valve
Inventor: FOSTER FRANK
IPC: G05D16/16
Filed: 1966-06-23
Abstract: 1,143,007. Fluid-pressure servomotor systems. WESTLAND AIRCRAFT Ltd. June 21, 1967 [June 23, 1966], No.28238/66. Heading G3P. A valve for controlling flow through an opening includes a valve seat 3, a pressure chamber 18 comprising a movable valve member 10 having a flange 12 extending towards the valve seat, a flexible sealing element 16 connecting the valve member to a wall member 6 supported centrally within the valve member, and resilient means 17 urging the valve member in an axial direction relatively to the valve seat, the valve member being slidably supported in a ducted member 5. The valve member has a hollow stem 13 communicating with ducts 7, 8 in which the pressure may be regulated by a relay such as that shown at 19 and by altitude and differential pressure limiters 20, 21. In the preferred embodiment, the valve controls the pressure in an aircraft cabin and the relay is subjected to cabin pressure (Pc) and to a low-pressure (Pt) obtained from the throat of a Venturi which may form the outlet from the seat 3. Air flowing into the cabin through the Venturi causes the valve to move into operating position against the spring 17, subsequent operation being controlled by the differential pressure on the relay 19. The spring 17 may be arranged to close the valve if a pressure higher than that in the cabin is connected to the relay 19. A pair of elements or a single preformed element may replace the element 16 to provide a flexible annular chamber communicating with the cabin through a series of holes in the skirt of the valve. The pressure in chamber 18 may be obtained from a pump or from the cabin supply duct.

Title: Method of detecting flaws in a body
Inventor: WARD JOHN BARRY
IPC: G01N21/91
Filed: 1961-08-04
Abstract: Flaws in a liquid impermeable surface having a deposit thereon are detected by applying a fluorescent liquid penetrant to the surface. A solution, preferably sodium silicate, is then applied to the surface to remove the deposit or render it removable and the body is inserted in a vibratory barrelling machine containing barrelling chips preferably formed from a mixture of ball clay, china clay and a particulate abrasive material.  This removes the penetrant and remaining deposit from the surface but leaves the penetrant in any flaws present in the surface. A developing powder, e.g. silica, is applied to the surface to adsorb or absorb the penetrant in the flaws.  The flaws are then visible when viewed in ultra-violet light. Specification 880,532 is referred to.

Abstract: 617,293. Coiling ; angular banding. GOSS, T. G. Sept. 24, 1946, No. 28501. [Class 83 (iv)] In a machine, for bending the tail ends of furniture &c. springs, depression of a pedal rod 27 throws in a clutch to rotate a shaft 8 driven from power means. A gapped gear 17 on the shaft 8 rotates a loosely mounted pinion 18 with a bending projection 23 and gearing with a spring-urged quadrant 21. On a fixed shaft 19 are fixed pins 24 and a spring-pressed pin 25. The tail end of the spring is held between the pins 24, 25 and on rotation of the projection 23 the tail is bent about the pins. When the gap of the wheel 17 registers with the pinion 18 the quadrant 21 restores the parts.

Title: Improved exhaust gas steam boiler or feedwater heater
Inventor: MATTHEWS FERGUS FREDERICK
IPC: F22B1/18
Filed: 1961-08-08
Abstract: 940,044. Heating steam boilers or feedwater heaters by waste gases. MARSHALL & ANDERSON Ltd. Aug. 8, 1962 [Aug. 8, 1961], No. 28560/61. Headings F4A and F4S. A steam boiler or feedwater heater has a lower annular compartment 14 disposed around a gas inlet conduit 19, the upper wall of the compartment being a tube plate 12 from which tubes 26 extend to an upper compartment of generally similar construction, i.e. an annular compartment 16 disposed around a gas outlet conduit 20. A space of square cross-section is left free of tubes within the tubed section between the ends of the conduits 19, 20 and is bounded on two opposite sides by flat vertical walls. An inclined baffle 29 which is attached on both sides to the walls extends upwardly and across the space between the conduits. Exhaust gases from, e.g. a diesel or other I.C. engine, enter the boiler by the conduit 19 and are deflected into the region of the water tubes 26 by the inclined baffle 29. Auxiliary baffles 30 assist in deflecting the gas into the region of the tubes. The gases flow among the tubes 26 around the boiler and re-enter the said space on the upper side of the baffle and are directed thereby to the outlet conduit 20. Water enters the lower compartment by the inlet connection 23 and flows through the water tubes 26, steam generated in the tubes being taken off from the upper compartment 16 which forms a steam and water space, by the connection 24. A single largediameter downcomer tube 27 is disposed behind the baffle 29 with respect to the gas inlet conduit. In a modification (Figs. 3, 4, not shown), the boiler functions merely as a feedwater heater in conjunction with a main boiler and as there is no steam space the upper compartment is smaller. The tube plates also are curved into the side walls and the upper compartment has a flanged cover providing access to the upper tube plate.
