Patent GB-509492-A (GB)
Title: Apparatus for mixing and storing temporarily a liquid and a gas
IPC: B01F15/02
Filed: 1937-10-15
Abstract: 509,492. Aerating liquids. MEADOWCROFT & SON, Ltd., W., and MEADOWCROFT, W. Oct. 15, 1937, No. 28100/36. [Class 14 (i)] An apparatus for aerating liquids comprises an inner chamber B acting as a gas reservoir and an outer chamber A acting as a mixing chamber and liquid storage reservoir. Compressed gas is passed into the chamber B by way of the pipe G, reducing valve G and passage g<1>, so that it is cooled by its expansion and acts to cool the chamber A. The valve G<1> is controlled automatically by the pressure prevailing in the chamber B, by means of a piston g <5> and lever g<2>. Liquid supplied to a reservoir D under control of a float valve d<1> is pumped by a pump E, through a passage e, past check valves e<1>, e<2>, to an injector device F, where it meets, and is mixed with, gas supplied from the chamber B by way of a reducing valve C and passage c. The latter passage has a branch to the chamber A. The mixed gas and liquid passes through a sight glass f to a spray pipe f<2> within the chamber A. As aerated liquid collects in the chamber A, it raises a float H, which acts through a lever h to open a valve h' This allows liquid to pass, by a pipe h<4>, to a piston device, not shown, to interrupt the driving motor of the pump E. When liquid is withdrawn from the chamber A by a pipe a<2>, the float H sinks, closing the valve h<1> and opening a valve h<2> which allows the liquid to return from the piston device to the reservoir D by the pipes h<4>, h <5>, and the pump to restart.

Filed: 1975-07-03
Abstract: 1505400 Immunological reagent AMERICAN CYANAMID CO 3 July 1975 [1 Aug 1974] 28140/75 Heading G1B [Also in Division C3] A diagnostic reagent comprises chemically and serologically inert polystyrene latex particles of particle size in the range 0À05 to 1 microns having adsorbed on the surface a cross-linked proteinaceous substance which is immunologically active, for example tetanus toxoid or human chorionic gonadotropin cross-linked with N-ethyl-N'-(3- dimethyl aminopropyl)carbodiimide hydrochloride. The reagent may be prepared by mixing the antigen or antibody with the cross-linking reagent in a buffered aqueous medium, heating or allowing the mixture to stand to effect cross-linking, separating unreacted cross-linking agent, for example by dialysis, then mixing the cross-linked antigen or antibody with the polystyrene particles, or alternatively mixing the antigen or antibody, cross-linking agent and polystyrene particles together in the first step.

Title: Improvements in percussion hand bombs
IPC: F42C14/02
Filed: 1922-10-18
Abstract: 200,010. Ciano, A. Oct. 18, 1922. Projectiles; fuzes. - Relates to grenades of the kind fired by means of a spring striker which is cocked by hand before the grenade is thrown and which is provided with three safety or retaining devices, one removed by hand after the striker is cocked, the second one becoming detached during flight, and the third adapted to release the striker on impact in any direction. According to the invention the first locking device is constituted by a key 27, 28, which passes through a slot in the striker stem 5 in such a way that it can be removed by hand by means of a ring 32 only after the striker is cocked. The removal of the key also withdraws a pin 29 from a weight 30 at the end of a coiled tape 31, which, when the grenade is in flight, unwinds and pulls a safety stop 20 from beneath the striker 6 and a locking jaw 22 from a ball 16. On impact, the ball is dislodged from between a fixed seat 18 and the tail 17 of a trigger 15, thereby releasing the striker. During the cocking operation, the tip 13 of the trigger is deflected against a spring 25 and then snaps under the head of the striker. The percussion cap 10 is in a plug 9 over a detonator 11. The grenade 'body 1 is shaped as shown of metal plate and is provided at the top with a filling tube closed by a screw plug 26.

Abstract: 806,402. Vehicle power steering. HYDRSTEER Ltd. Sept. 30, 1955 [Oct. 1, 1954], No. 28353/54. Class 79(5) In a vehicle power-assisted steering mechanism an intermediate section 5 of the track rod is pivotably connected to pivoted arms, one of which is formed by the drop arm 4 pivotally connected at 10 to an arm 11 pivoted to the intermediate section 5 and to a part of a power control valve 13. As further shown in Figs. 1 and 2, the section 5 is connected to track rod link sections 6, 7 and is pivoted at 9 to the other pivoted arm 8 carried on a fixed pivot 8<SP>1</SP>. Manual rotation of the steering column 2 causes movement in the valve 13 of the order of 0.020 inches, such movement being accommodated by relative movement of the arms 4, 11 about the pivot 10 and initiating power steering. The ratio of the distances a, b varies the rate of response of the valve 13 to manual input to the steering gear 1 and the "feel" of the steering. In another embodiment, Fig. 3, the arm 11 pivoted at 10 to the arm 4 is connected at its upper end to the section 5 and at its lower end to a part 18 of the valve 13, the other part of the valve being connected at 19 to an extension of the arm 8. In further embodiment, Fig. 5, the arm 4 is connected by a resilient member 21 to an arm 20 corresponding to the arm 11 in Fig. 3.
