Title: Improvements relating to apparatus for dispensing pastes, creams and liquids
Inventor: GREEN EDWARD RAMSAY
IPC: A47K5/12
Filed: 1955-08-12
Abstract: 818,363. Reciprocating pumps. NEWTON, CHAMBERS & CO. Ltd. Dec. 20, 1955 [Aug. 12, 1955], No. 23283/55. Class 102(1). In a liquid dispenser comprising a liquid container 3 secured to a body 1 having a cylinder bore 16 communicating through a port 25 with the container 3 and through a valve 18 with a nozzle 19 and housing a piston 15 reciprocated in one direction by a lever 20 and returned by a spring 17, the volume of liquid dispensed is pre-set by adjusting the position at which communication between the pressure chamber 22 and the port 25 is cut off. In the embodiment shown four positions are provided by three axially and circumferentially spaced bores 24 which communicate with an axial bore 23. By rotating the piston 16 one or other of the bores 24 is brought into alignment with the port 25. The fourth position is obtained when cut-off is controlled by the front face 15A of the piston. The angular position of the piston is set by engagement between the side faces of a square head 27 and the cheeks of the lever 20. In a modification the bores 24 are replaced by grooves in the periphery of the piston. In a modification the piston is angularly located by means of a splined end engaged by a splined plate; these pistons have a corresponding number of bores/ splines. The container 3 is secured to the body 1 by a bayonet fastening and locked by a bolt accessable from the face of the body which engages a wall plate. The body is locked to the wall plate by a spring loaded plunger releasable by a special key. Air is permitted to enter the container 3 when a waisted portion 15B uncovers an air inlet port 28 separated from the port 25 by a barrier 29. Specification 818,364 is referred to.

Title: Improvements in the production of catalysts for the synthesis of ammonia
IPC: B01J37/14
Filed: 1923-09-20
Abstract: Catalysts for the synthesis of ammonia are prepared by heating in a current of oxygen a mixture of artificial or natural iron oxides with substances possessing a high combination heat wth oxygen until the temperature becomes near or equal to that of ebullition.  Instead of or in conjunction with oxides of iron may be employed oxides of cobalt, nickel, manganese, chromium, molybdenum, tungsten or uranium, or compounds producing the oxides may be used.  Heat-irreducible metal oxides, such as alkaline earth oxides, or metals giving rise thereto may also be present. The substances possessing a high combination heat with oxygen are defined as those substances giving out the same as or a greater number of calories per gram-atom than carbon does under combustion; carbon, magnesium, aluminium and calcium are given as instances, and catalytic poisons are excluded. According to the example, powdered magnetite is mixed with calcined dolomite, carbon and either aluminium, calcium or magnesium, and a current of pure oxygen is projected on to or passed through the heated mass until violent ebullition ceases and the mass on cooling turns pasty; the cooled product is broken up for use.  Specification 197,199 is referred to.
