Patent GB-145089-A (GB)
Title: Process whereby neutral oils can be profitably recovered from their "foots" or soap-stock
IPC: C11B13/02
Filed: 1920-06-17
Abstract: Oil is recovered from the " foots " obtained when cotton seed or other fatty oil is refined with caustic soda.  The foots are treated to reduce the stability of the emulsion by diluting with water, and, preferably, heating and adding about 2 per cent of boric or other acid or an alkaline salt such as sodium carbonate. The treated foots with or without settling are passed through a centrifugal separator to separate an emulsion which contains most of the oil, and this emulsion is destroyed by salting out the soap, by mixing in tri-sodium phosphate or other electrolyte, by breaking the soap with sulphuric or other acid, or by freezing, so that the oil can be separated by settling or by centrifuging.

Title: Improvements in method of and means for burning pulverulent fuels
IPC: F23C99/00
Filed: 1920-06-18
Abstract: 162,958. Lotz, C. W. June 18, 1920. Pulverulent-fuel furnaces; fuel, feeding.-In a pulverulent-fuel furnace, having a reverting flame, wherein the air blast and suspended fuel are directed downwardly, the direction of the entering fuel stream is varied to suit varying working conditions. Fig. 3 shows a vertical combustion chamber b with the fuel-nozzle a<11> and the: outlet c adjacent to each other so that the reverting flame initiates combustion of the entering fuel, which takes place approximately at g. The fuel stream induces regulable supplies of secondary air to the interior and exterior of the flame loop through valves f, f<1> and a casing d, Fig. 5, and the chimney draught, regulable by a pivoted damper, induces a further supply, through the door i, across the floor of the cham. ber which it protects, this air following the loop peripherally as indicated and cooling ash particles which can be removed through openings j, i<1>. The fuel-nozzle comprises the air blast and fuelpipe a<1> connected with a flattened nozzle a<11>, which retards the fuel velocity and leads to an inclined passage d<1> surrounded by the secondary air passages; the passage d<1> normally directs the fuel somewhat centrally within the chamber and is so proportioned that contact of the flame with the side walls is avoided. A hinged flap e, attached to the fuel-nozzle and operated by a. rod e<1> which passes through the setting, regulates the direction of the entering fuel stream. When starting the furnace the flap e is turned back to the left, Fig. 5, until the desired temperature is obtained, when the flap is adjusted as desired. As the load decreases, the flap e is moved to the right, Fig. 5, and as the load increases the flap is moved to the left.

Abstract: 428,504. Brakes ; hinges and pivots. CROWN BEDDING CO., Ltd., and WALLIS, L. S., 46, Macdonald Street, Birmingham. June 6, 1934, No. 16786. [Class 103 (i)] [See also Group XXV] A brake device for controlling the movement in one direction of a member about a fixed shaft or the rotation of a shaft within a stationary member comprises as applied, for example, to a folding bed pivoting about a fixed shaft a, a brake band h attached to pins k, l at unequal distances from the axis of the shaft, on a bar c slidable in a bracket b secured to a member pivoted on the shaft. A spring m urges the bar c towards an adjustable stop e so that one part of the band normally contacts the shaft. In lowering the bed from the normal vertical position, the parts move in the direction of the arrow and the self-wrapping action of the band h causes it to grip the shaft, the bar sliding until it meets the stop e which thus limits the braking action. The brake is however ineffective during the raising movement of the bed. In other applications the shaft may rotate and the member carrying the bar c be stationary.
Patent GB-778093-A (GB)
Title: Hydraulic pressure regulating device
IPC: B60T8/26
Filed: 1955-06-10
Abstract: 778,093 Hydraulic brakes. TEVES, H. and TEVES, E. A., [trading as TEVES MASCHINEN-UND ARMATURENFABRIK KOMM.- GES., A.]. June 10, 1955 [July 14, 1954], No. 16787/55. Class 103 (1). In an hydraulic pressure regulating device, particularly for use in regulating the distribution of braking force in vehicle brakes, having a stepped piston operated by pressure from a pressure-generating means (for example a master cylinder), a valve controls communication between the annular gap formed ahead of the larger diameter end of the piston and the reservoir and is operated by spring force due to the low pressure range and, when the pressure increases is closed by means of a piston or the like which is acted upon by the pressure in the high pressure space such that the pressure in the annular gap rises as the working pressure rises. In the embodiment illustrated, showing the rest position of the device, the hydraulic pressure regulating device 1 is situated between the master cylinder and the pipe leading to the rear wheel brake cylinders. As pressure from the pressure generating means (the master cylinder), via pipe 2, increases, the control piston 3 is displaced to the left and the pressure in the high-pressure space 11 rises. Since the pressure exerted by the pressure generating means is initially low, the annular gap 4 communicates with annular channel 5 via bore 12 and valve opening 13 and bore 14. When the pressure in the high-pressure space 11 reaches a given value, piston 15 is displaced and opening 13 closed by valve 9 so that the pressure relief of the annular gap 4 is prevented. A further increase of pressure allows pressure medium to pass from the annular gap 4 only when the pressure in the annular chamber 5 is greater than the pressure urging valve 9 on to its seat. The pressure in annular gap 4 rises until it reaches a value equal to the pressure in the space 11 and then no further transmission of pressure takes place. A spring loaded valve 10 is provided to relieve any excess pressure set up in annular gap 4. By suitably dimensioning the regulating device, equalisation of the front and rear wheel braking power is obtained at the commencement of braking. Upon the attainment of a predetermined pressure in the master cylinder, no further increase in pressure is transmitted by the regulating device whereupon the front wheel brake power becomes greater than the rear wheel brake power to take account of the dynamic axle load displacement.

Title: A process for the manufacture of a design-bearing plastics product
IPC: B32B27/00
Filed: 1964-04-23
Abstract: A process for the manufacture of a polyvinyl chloride sheet bearing a design diffused therethrough comprises applying the design to to the surface of a polyvinyl chloride base layer with the aid of a coloured lacquer, evaporating the solvent from the coloured lacquer, applying a polyvinyl chloride paste in a thin layer over the design, gelling the paste at 130 - 200 DEG C. to fuse the two layers, and cooling, the process being characterised in that the dye and/or pigment of the coloured lacquer diffuses only to a negligible extent at room temperature, and has such a small diffusion velocity at the gelling temperature that owing to the thinness of the applied layer the dye and/or pigment can migrate to the top and bottom surfaces of the fused sheet without there being so great a lateral diffusion as to mar the design.  The polyvinyl chloride base may consist of a carrier, e.g. paper, plastics or textile such as jute fabric, having a coating of polyvinyl chloride.  Specified dyes and pigments include Fanal yellow green G, Resoline Red FB, Cibacet Yellow 2 GC, Cibacet Blue GF, Micro setile Black B.
