Title: Improvements in or relating to oil filters
IPC: B01D33/80
Filed: 1935-01-30
Abstract: 451,179. Filters. RUSSELL, F. C., Lundy, Warwick Road, Hale, and BRADBURY, J. H., 8, Broadway, Ashton-on-Mersey, both in Cheshire. Jan. 30, 1935, No. 3019. [Class 46] The invention relates to oil filters having a rotary cleaning member or a rotary cleaning action and consists in imparting regular rotary movement to a part of the filter by means of a motor actuated by the oil fed to or leaving the filter. A filter element comprises superposed discs on a spindle 11 within a container 10, these discs being interspaced with other discs which form a fixed comb. The spindle 11 is given intermittent rotary movement by means of a roller-type ratchet with operating lever 31. The ratchet is enclosed in a body part 13 which is extended at one side to form a cylinder 18 for the piston 24 of an oil motor. A central portion of the cylinder 18 is cut away so that the lever 31 can engage in a waist portion of the piston. The waist portion is also engaged by a roller 28 at the end of a lever 27 which operates a sleeve valve 17 controlling the flow of oil from a passage 6, which opens within the filter element, through a passage 20 fitted with a control valve to one end of the cylinder 18. In operation, the oil moves the piston against the pressure of a spring 24<a> and the lever 31 turns the spindle 11. At the same time the lever 27 is also moved by the piston to a position in which it receives a sharp impulse from a spring 29 and moves the sleeve valve with a snap action to a position in which the valve shuts off the flow of oil to the operative end of the cylinder and connects this end through a passage 19 to a pipe 35 which conducts the oil back to the oi1 sump. The piston and the sleeve valve are returned by the spring 24<a> to their initial positions. A modification is described in which the oil pressure is used to move the piston in both directions. Specifications 145,339 and 215,098, [both in Class 46], are referred to in the Provisional Specification.

Filed: 1931-01-30
Abstract: 371,936. Cooling gases. MAIN, J. A., Clydesdale Ironworks, Possilpark, Glasgow. Jan. 30, 1931, No. 3060. [Class 29.] Gases are cooled by direct contact with water in a well, the gases being passed down between cylinders 1, 3 sunk in the well and then up between cylinders 3, 4 to the air-delivery pipe 3a. The well water rises within cylinder 4 and is sprayed into the air through perforations in this cylinder. The water from the sprays is pumped up pipe 8 and may return down a spiral pipe 9 provided with perforations from which the water may spray and cool the entering air. The well water enters through a strainer 5 and filter 6 on the bottom of member 4. By raising this member the entry of water may be controlled and if raised to shut off entry completely the water runs out of cylinder 4 into the bottom of the cylinder 1 through the strainer 5 and cleanses the latter.
Patent GB-612712-A (GB)
Title: Processes of preparing primary aliphatic amines
IPC: C07C209/48
Filed: 1945-02-08
Abstract: Aliphatic primary amines having ten or more carbon atoms in the molecule are prepared by catalytically hydrogenating a mixture of an aliphatic carboxylic acid nitrile having ten or more carbon atoms in the molecule and a secondary aliphatic amine in which each aliphatic chain contains ten or more carbon atoms. Preferably each chain of the secondary amine contains as many carbon atoms as there are in the molecule of the selected nitrile. Generally the quantity of secondary amine used is from 50 to 200 per cent by weight of the nitrile. Preferably, an aliphatic nitrile having ten or more carbon atoms is hydrogenated to obtain a mixture of primary and secondary aliphatic amines and the secondary amines produced are used alone or in the admixture to foster the production of primary amines in the hydrogenation of another batch of the nitriles.  Hydrogenation is effected in liquid phase at elevated temperature and pressure, preferably in the presence of ammonia; suitable catalysts are nickel and platinum.  In examples: (1) commercial stearic acid nitriles are hydrogenated, the product distilled to remove primary amines and the residue consisting essentially of secondary amines is added to a further batch of the nitriles which are hydrogenated as before, the respective yields of primary amines being 64 and 84 per cent; (2) nitriles of hydrogenated fish oil acids (C20-C22 chains) are treated as in (1).  Stearic acid nitrile may be hydrogenated in the presence of secondary lauric amine.  Other starting materials specified are palmitic and lauric acid nitriles.  Specification 439,274 is referred to.

Abstract: 542,345. Exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., PRIEST, T. P., and THOMPSON, G. W. March 20, 1941, No. 3788. [Class 40 (iv)] In a party-line arrangement in which revertive calls are made directly by code ringing, a single pulse of ringing current is used to call the exchange, the calling circuit being closed at a pre-determined time after the cessation of the pulse provided no further pulse follows. Relay R responds to magneto ringing current, closes a charging circuit for a large-capacity condenser QB and connects up relay T, which remains operated in series with the charged condenser for a period of the order of 3 seconds after the release of R. Relay A energizes on the release of R, and provided the latter relay does not re-operate the relapse of T completes the calling circuit. If R does re-operate, a circuit is made for relay B, which locks under the control of A and prevents the completion of the calling circuit. Relay A is made slightly slow-tooperate as well as slow-to-release to obviate any effect from a momentary flick of R during a ringing pulse.
