Title: Improvements in or relating to brakes
IPC: B60T11/224
Filed: 1940-10-11
Abstract: 544,552. Hydraulic brakes. BENDIX AVIATION CORPORATION. Oct. 11, 1940, No. 15184. Convention date, Nov. 3, 1939. [Class 103 (i)] A device adapted to be interposed in a vehicle hydraulic brake system adjacent a wheel brake operating cylinder acts to step-up the pressure in the cylinder and may become effective only when the shoe clearance has been taken up so that this clearance is taken up relatively quickly. It comprises a differential piston 28 slidable in a casing 15 screwed into the inlet passage 23 of a wheel brake cylinder 19 and normally held in the position shown by a spring 39, in which a ball check valve 34 is unseated by engagement of a rod 43 with the end cap 49 of the casing to which is connected the pipe 14 leading from the master-cylinder. In operation liquid is initially supplied directly to cylinder 19 through the passage 42 and if the spring 39 is of such a strength that the brake-pull off springs are overcome before the spring 39 is compressed the shoe clearance is rapidly taken up by direct supply of liquid through the passage 42. The piston 28 is then moved by the differential pressure acting on the ends .thereof thus seating the valve 34 and pressure is transmitted to the cylinder 19 at an increased ratio.. The device may be mounted on each of the cylinders 19 of the four wheels of a vehicle or to obtain a relatively lower pressure on the front wheel brakes, the device may be removed from the front wheels cylinders the pipe connection 45 being adapted for screwing into the bore 24 of the cylinders 19. It is stated in the Specification as open to inspection under Sect. 91 that by making the device reversible, the braking on the front wheels could be reduced to one fourth of the original value: This subject' matter does not appear in the Specification 'as accepted.

Abstract: 1313115 Extracting solutions; solid/liquid contact T MATSUMOTO 2 April 1970 [3 April 1969 6 June 1969 30 Aug 1969] 15737/70 Heading B1F A method for treating a material comprises bringing a material to be eluted into association with a carrier, forming an interface between a first liquid and a second liquid, the material having a greater affinity for the carrier than for the first iquid and a lesser for the carrier than for the second liquid, after formation of the interface introducing the carrier into the first liquid and allowing the carrier and material to be eluted to pass through the interface so that the material is eluted from the carrier into the second liquid. In Fig. 17, xanthine oxidase is extracted and purified using calcium phosphate gels as carriers by rotating rotor 52 introducing a phosphate buffer solution containing 10% by weight of ammonium sulphate through pipe 68 and passage 59 into compartment 53, introducing a mixture of a raw enzyme extract in a similar phosphate buffer solution and calcium phosphate gel via tube 69 and passage 65 into chamber 53 so that an interface is formed between the two buffer solutions, and the gel passes through the interface due to centrifugal force carrying xanthine oxidase with it which it gives up to the ammonium phosphate buffer solution. In Fig. 15, in the extraction of raw xanthine oxidase solution forming the upper layer in reactor 25, the middle layer was phosphate buffer solution and the lower layer sodium chloride solution. DEAE cellulose as carrier was allowed to settle down through the layers; when impure xanthine oxidase was picked up by the cellulose on passing through the top layer, xanthine oxidase was eluted into the buffer solution, and impurities were eluted into the sodium chloride solution. To wash the DEAE cellulose, the brine was replaced by water, and screw conveyer 39 was rotated to convey washed DEAE cellulose to the top of chamber 28 and hence back into chamber 25 for further treatment.
