Abstract: 650,992. Supply systems for space discharge lamps. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. May 14, 1948, No. 13229. [Class 38 (iv)] Automatic reduction of the heating current supplied from a transformer L2 to the filamentary electrodes H<SP>1</SP>, H<SP>2</SP> of a discharge lamp F when the lamp starts is effected by including in each circuit between the electrodes and associated secondary windings L5, L6, a choke L3, L4 respectively of inductance less than that of the associated secondary winding and arranged such that the voltage across the secondary winding is opposed by the voltage across the respective choke due to the lamp current, and hence effect reduction or cancellation of the heating current. A condenser C may be included in the discharge circuit to improve starting. Specification 31284/46 (as open to inspection under Sect. 91), is referred to.

Title: Improved method of applying pressure to the surface of newly formed concrete or like cementitious products
IPC: B28B3/00
Filed: 1952-05-27
Abstract: Pressure is applied to the surface of a newly-formed concrete or asbestos-cement product, e.g. to improve the strength of the product and pretension the reinforcement, by forming a fluid-tight film on the surface and applying a fluid under pressure to the surface.  The film is formed by reaction between one or more water-soluble salts of alginic acid and one or more water-soluble calcium or other water-soluble metal compounds, and is inert to the fluid.  The invention is described in connection with the making of a pipe.  The sodium or ammonium salts of alginic acid may be used, and preferably these salts are added to the water by which pressure is to be applied to the interior of a newly-formed concrete pipe.  Thus, sodium alginate is added to the water prior to application of the pressure and reacts with the water-soluble calcium compounds in the water of the concrete mix to form on the interior of the pipe a film of insoluble calcium alginate; this film builds up by degrees, and some lapse of time is desirable before pressure is applied. Alternatively, prior to the introduction of the pressure fluid the alginate solution may be applied to the concrete surface as by spraying, thus producing the water-insoluble film.  As a further alternative, the concrete surface may first be treated with a solution of one or more water-soluble compounds, e.g. a water-soluble salt of calcium, chromium or zinc, and then with alginate whereby an insoluble film is applied to the concrete before the pressure water or other fluid is introduced.  To the alginate solution, may be added rubber latex bitumen-bentonite emulsions or oily substances. Specification 717,946 is referred to.

Title: Tandem pressure fluid control valves
Inventor: BUELER RICHARD CHARLES
IPC: B60T15/04
Filed: 1964-04-03
Abstract: 1,002,091. Valves; compressed air brakes. WAGNER ELECTRIC CORPORATION. April 3, 1964, No. 13963/64. Headings F2F and F2V. A reaction piston 79 and a relay piston 72 are moved downward upon depressing a brake pedal so that a valve member 85 closes an outlet chamber 54 from atmosphere; further movement of piston 79 causes unseating of an inlet valve 62 so that pressure fluid from the reservoir 10 flows through chamber 54 and operates slack adjuster 14. Concomitantly pressure fluid in chamber 54 traverses a passage 86 in the stem of valve 62 and enters an application chamber 87 as well as flowing via a line 19 and a ratio-adjusting valve 20 into a ratio chamber 93 whereby the relay piston 72 is independently lowered to first isolate another outlet chamber 35 from atmosphere; further movement of the piston 72 unseats another inlet valve 43 and interconnects a further reservoir 4 to chamber 35 whereby another set of slack adjusters 9 are operated. When the reaction force created by the fluid in chambers 87, 93 equals the manual force on the piston 79 the latter moves up against a metering spring so that the inlet valve 62 is lapped and direct " feel " of the braking effort is afforded the operator; the inlet valve 43 is also lapped by the pressure in chamber 35 acting on the piston 72. Upon removing the manual force on the brake pedal the adjuster actuators 8, 13' are exhausted through ports 40 and 61 and the parts return to the positions shown. Since the effective areas of chambers 87, 93 are equal and opposite to that of the piston 72 in chamber 35 a 1: 1 ratio between the pressure in the branches 2, 3 is realized. Rotation of valve 20 reduces this ratio by venting chamber 93. Failure of one branch 2, 3 does not prevent the other one from operating with appropriate " feel " and a minimum of lost stroke. Valve 20 also provides for sequential operation of each set of brakes. In another form the stem of valve 62 consists of two separate axial parts between which is formed the exhaust valve which controls the venting of chamber 54 to atmosphere.

Title: Quick release mechanism
IPC: B64C1/32

Abstract: 852,092. Discharging from aircraft. NATIONAL RESEARCH COUNCIL. May 1, 1958 [Aug. 12, 1957], No. 13975/58. Class 9(2). [Also in Groups XXII and XXXIII] Mechanism for releasing a position indicator from aircraft in the event of a crash or aerial break-up comprises a cable 1 secured at 2 at the front end of the fuselage and extending rearwardly for attachment to a device 6. Similarly, a transverse cable 8 secured at 9 and 10 to the wing tips has an intermediate connection 12 with a further cable 11 which at its rear end is secured to a device 13. The devices 6 and 13, which are constructionally similar, constitute releasable fastenings for a thin steel strap 15 which retains a crash position indicator 14 on the top surface of the tailplane 7. Each device 6, 13 comprises a U-section plate member 29 to which is secured a spring housing 27 and a pair of rollers 30, 32, the strap 15 passing freely over roller 30 and being attached to roller 32, which is used to tension the strap by the use of a screwdriver on slotted head 36 against the action of a ratchett device 33, 34. The housing 27 encloses a compression spring which acts on a piston secured to an extension of a wire loop 23 surrounding strap 15 and attached by an element 22 to the cable 1 or 11 which is thereby tensioned. Deformation of the aircraft structure as the result of a crash or similar occurrence will cause one or both of cables 1, 11 to be tensioned still further or slackened, thereby causing the loop 23 to cut the thin strap 15 so that the indicator 14 may be ejected from the aircraft by a leaf spring (not shown). Specification 852,091 is referred to.

Abstract: 438,132. Raising liquids by gas pressure. COOMBS, J. A., 12, Princes Park Avenue, Golders Green, London. May 11, 1934, Nos. 14224 and 37111. [Class 102 (ii)] In liquid-raising apparatus in which the liquid, e.g. sewage, is drawn into a chamber 10 and subsequently discharged therefrom by compressed air, the air 31 and/or liquid 17, 21 valves are controlled by a pressure sensitive device 33 operating in accordance with the air pressure and liquid level in the chamber. The device 33 comprises two chambers 42, 43, closed by diaphragms or pistons carried by a frame 46, and connected respectively to an air pocket 36 at the bottom of the chamber 10 and to the air suction and supply pipe 29. The pressure in the air pocket and chamber 42 varies with the rise and fall of liquid in chamber 10 ; rise of pressure in chamber 42 corresponding with fall of pressure in chamber 43 and vice versa. Such variations in pressure raise or lower the frame 46 thereby actuating a pilot valve 34 controlling movement of a valve 35, which may be of the kind described in Specification 6804/10, [Class 102 (ii)], and which regulates admission and exhaust of air to and from cylinders 57, 60 operating the air and liquid valves 31, 32, 17, 21. When two pumping chambers 10, 11 are used, the exhaust air from one being recompressed for emptying the other, the second chamber is also provided with a pressure sensitive device 33 and pilot valve 34 to assist in controlling the valve 35. If a single chamber 10 is employed, two pressure sensitive devices may be employed to operate pilot valves at top and bottom liquid level respectively. Air losses in the system may be compensated by a snifting valve 63 acting automatically on drop in pressure or actuated periodically by air pressure under control of the valve 35. The latter may also control the cyclic operation of a liquid byepass valve on the top of the chamber 10 to prevent liquid flowing into the air system. An air vessel 78 supplied with air at reduced pressure may be inserted in the liquid discharge pipe 23. The compressor motors 24 are started and stopped by a liquid level sensitive device in the suction sump to which the chambers 10, 11 are connected.
