Title: Improvements in the manufacture and production of agents for combating and destroying pests
IPC: A01N59/24
Filed: 1928-08-27
Abstract: 322,179. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 27, 1928. Manures. - Agents for destroying pests may comprise calcium cyanide diammoniate or other double compounds of ammonia with cyanides which are readily decomposed by moisture, together with inert organic liquids. Such ammoniates liberate ammonia bv the action of moisture and may therefore act also as fertilizers. Optional additional ingredients include wetting agents and hygroscopic salts such as calcium nitrate or magnesium chloride.
Patent GB-591818-A (GB)
Title: Fluid flow meters
IPC: G01F1/28
Filed: 1944-12-08
Abstract: 591,818. Fluid-flow meters. BENDIX AVIATION CORPORATION. Dec. 8, 1944, No. 24667. Convention date, Nov. 18, 1943. [Class 69 (i)] A vane-type fluid flowmeter has a metering chamber 20 in which the outlet is formed by an arcuate slot 17 of progressively increasing width. In conjunction with a fixed portion 35, a moving vane 33 defines a segmental space into which opens an inlet 14 and an exposed portion of the outlet slot 17. The vane is mounted on a hub 34 which covers the slot except where it is notched as at 53. The fluid flowing through the meter acts on the vane against a restoring force provided by a spring so that movement of the vane relative to the slot is dependent upon the rate of flow and the area of the outlet exposed by the hub. The Specification as open to inspection under Sect. 91 comprises also modifications in which (i) the arcuate slot is of constant width and the variation in area of the outlet orifice is due to variation in the exposed length of the slot, and (ii) the flow recordings are transmitted to a remote point through a magnetic coupling. This subject-matter does not appear in the Specification as accepted.

Title: Valve operating device for internal combustion engine
IPC: F01L9/10
Filed: 1963-06-21
Abstract: 1,043,383. I.C. engine valve gear. MITSUBISHI SHIPBUILDING & ENGINEERING CO. Ltd. June 21, 1963 [June 27, 1962], No. 24854/63. Headings F1B and F1K. In an I.C. valve operating device in which a piston 19, Fig. 1, disposed coaxially with a plunger 12 connected to the valve stem 2, has a larger fluid bearing area and a smaller stroke length than the plunger, fluid under pressure is introduced through control means 22 into at least one pressure chamber 7, containing the plunger and piston, so that the piston is subjected to the pressure fluid to open the valve during a first part of the valve opening period and then only the plunger is acted on during the latter part of the period until the valve is fully opened. Piston valve 28, which is actuated by cam 30, directs pressure fluid from port 25 to either ports 23 and 10 or to ports 24 and 11. In the position shown in Fig. 1, pressure fluid entering port 11 passes along grooves 20, in a piston 19 fixed to stem 2, into chamber 8 so that the valve stem is moved upwardly to seat valve 4. Fluid present in chamber 7 is forced through port 10 and through ports 23 and 26 to a fluid collection tank (not shown). When the cam causes lift of piston valve 28, pressure fluid is directed to chamber 7 and is ducted through holes 18, so that pressure is applied to the upper surfaces of piston 17 and plunger 12 which then move downwardly as a unit, opening valve 4. Piston 17 moves downwardly until it abuts partition 9 and then the plunger 12 completes the opening movement. Air present in the oil is vented to atmosphere when protrusion 15 emerges from space 13 and needle rod 16 emerges from vent 14. During the valve closing movement needle rod 16 enters vent 14 and protrusion 15 enters space 13 so that an hydraulic buffer is provided by oil present in the upper part of space 13 which can only escape through the predetermined clearances between mating parts. In another embodiment, stem 2 Fig. 8 (not shown) is formed with a piston 50 which is abutted by a piston 51 and pressure fluid is applied to piston 50 either through passage 53 or in a modification through passage 56 when the latter is cleared by downward movement of the piston 50. In a further modification the fluid control valve may be actuated by an electric solenoid and in low speed engine applications the pressure fluid may be air. The valve gear may be included in engine reversing gear having separate cams 30, 30<SP>1</SP>, Fig. 12B (not shown) on an axially displaceable cam shaft. In all embodiments the valve closing movements may be effected by a spring instead of fluid pressure.

Abstract: 1,122,618. Advancing hydraulic mine roof supports. BERGWERKSVERBAND G.m.b.H. June 3, 1966 [June 3, 1965], No.24935/66. Heading F1P. An automatically advanceable hydraulic mine roof support unit has a periodically extended feeler member which when the coal face B and/ or the conveyer C is a predetermined distance away from the support serves to initiate the release, advance and resetting of the support unit. A coal face feeler member 72a and a conveyer feeler member 72b are held retracted within cylinders 71a, 71b by continuous application of low pressure air from a line 9 until such times as they are extended through apertures 81a, 81b in protective casings 80a, 80b until arrested by contact with the coal face B and conveyer C by a pulse of high pressure air admitted through a camactuated valve 6 in a high pressure line 10. When the face B and conveyer C have so far advanced that the periodically extended feelers are able to make a full stroke, arms 74a, 74b carried thereby open three-way valves 13a, 13b in high pressure to a line 15 containing actuators for the main hydraulic valves controlling the supports. The cam 4 for actuating valve 6 is mounted on an indexed shaft 3a which also carries a cam 5 for controlling a valve 16 which in turn controls the supply of compressed air to cylinders 17, 18 to effect return of valves 13a, 13b to their inoperative position.
