Abstract: 822,519. Refrigerators. HEAT PUMP & REFRIGERATION Ltd. March 13, 1958 [March 13, 1957], No. 8258/57. Class 29 A reversible compression heat pump having indoor and outdoor heat exchangers 2, 3 respectively, has a first connection between the ends of the heat exchangers remote from the compressor including a restrictor 20 and a shut-off valve 19 and a second connection by-passing the shut-off valve including a restrictor 22 and connected to the indoor heat exchanger 2 at a point intermediate the ends. The restrictors are preferably capillaries and resistance to flow through the second connection is greater than that through the first. The shut-off valve is operated with the reversing valve and when the indoor heat exchanger is used for cooling is open. When the indoor heat exchanger is used for heating the shut-off valve is closed and liquid refrigerant accumulates at the bottom of the heat exchanger below the connection with the by-pass line. Air circulates over the compressor casing and may be directed to waste or to the space to be heated by means of an adjustable vane in the heat pump housing (Fig. 2, not shown). A capillary may be included in the line 17 when the capillary 20 is dispensed with and the capillary 22 made smaller. According to the Provisional Specification the first connection may include a refrigerant sub-cooler.

Abstract: 433,433. Gas heating-stoves. HOLE, C., and RAYTONIC HEATING CO., Ltd., 176, Windsor House, Victoria Street, Westminster. March 18, 1935, No. 8331. [Class 126] [See also Group XII] A gas-heatedradiator comprising a heat-storage unit of refractory material 5 associated with a gas fire using radiants 1 is provided with an auxiliary source of heat, in the construction shown consisting of a gas burner 25, for maintaining the temperature of the heat-storage unit when the supply to the main burners 2 is cut off or materially reduced. In the stove shown the gases from the incandescent fire pass through a perforated supporting plate 6 into the mass of refractory material 5 contained in a casing 4, and from thence by an outlet 15. Air is heated in passages 20, 21 around the casing 4 and passes out through openings 22 in the front of the stove. It is moistened by water from a reservoir 9 which is fed by wicks passing through perforations in the bottom, or over the top edges of the sides, to refractory material 7 arranged above the casing 4. Air also flows up a space 14 at the back of the stove and is delivered around the outlet nozzle 15 to improve the draught by ejector action. The auxiliary burner 25 may be replaced by an electric heater within or outside of the refractory material 6, or it may be replaced or supplemented by a burner 29. The casing 3 may be provided with end pieces 27 telescoping into it, so that its width may be varied, or a number of stoves may be joined by connecting pieces, as shown in Fig. 3, which replace the members 27 except at the ends of the assembly.

Patent GB-160776-A (GB)
Title: Method of converting wood into sugar and other products
IPC: C13K13/00
Filed: 1921-03-18
Abstract: Mucic acid is made by oxidizing galactose obtained by hydrolyzing western larch and like woods.  The hydrolyzing solution may be an acid solution containing acid from 1/4 to 2 1/2 per cent of the dry weight of the wood to be treated. The operation preferably takes place in a diffusion battery through which the solution is passed in counter-current to the wood.  The wood is heated to the temperature at which it is to be treated before being placed in the vessels. After the solution is withdrawn from a vessel, the vessel may be evacuated before introducing another charge of solution to evaporate the liquid left in the wood and to open out the wood.  The wood after treatment is used for fuel or for making paper, millboard, &c. The mother liquor from the mucic acid, which contains nitric acid, nitrous acid, oxalic acid, &c. may be used as the hydrolyzing agent. If it is necessary to concentrate the galactose solution the stronger mineral acids may be neutralized with alkalies, without neutralizing the organic acids, to prevent corrosion of the apparatus.  The Specification as open to inspection under Sect. 91 (3) (a) states that the process may be applied to cotton seed hulls, corn cobs, shells of various sorts of nuts, wing nut meal, &c.  When corn cobs are treated the chief product is laevoxylose, which may be oxidized to trioxyglutaric acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 400,842. Testing hardness. CRAEMER, P., Herzebrock, Westfallen, Germany. March 23, 1933, No. 8823. Convention date, March 30, 1932. [Class 106 (ii).] A hardness tester comprises a penetrating member 9 mounted on a sliding rod 8 and subjected to a standard load by a spring 11, the penetration of the member into the test piece P being read off on a scale 12 by means of a pointer 17 movable on the projecting end of the rod 8. The test piece P is raised by a screw 3 until the spring 11 is compressed and the test piece abuts against a fixed bush 10. As the pressure member 9 is lifted, the rod 8 slides through the cap 12 on the circumference of which the scale is marked. The depth to which the member 9 penetrates the test piece varies the movement of the rod 8 and exposes a corresponding amount of a screw thread 13 above the cap 12. A pointer 17 carried by a boss 15 working on the thread 13 is screwed down into contact with the scale, the angle of rotation giving a measure of the hardness of the test piece.

Title: Improvements in or relating to liquid pressure braking systems
IPC: B60T13/16
Filed: 1947-04-01
Abstract: 622,617. Vehicle brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. April 1, 1947, No. 8853. [Class 103 (i)] In a fluid-pressure braking system in which the brakes are applied by restricting the flow of idly-circulating fluid in a pump circuit to build up pressure on the rear face of the piston of a master cylinder, the pump circuit is branched between the pump and the point at which the flow is restricted, the branch leading to additional fluid-pressure apparatus through a valve urged towards a closed position by the pressure in the master cylinder and urged towards an open position by the liquid-pressure in the pump circuit. The fluid is circulated by a pump 12 through pipe 17, chamber 11, pipe 20, chamber 16 and pipe 19, and is caused to build up pressure on the rear face of piston 7 by a pedal-operated control 13 which restricts the circulation. Pipe 17 is connected to additional wheel-brakes 25 by pipes 18, 26, through a valve 22 having the rear face of its plunger 32 in operative connection with the forward face of piston 7 by pipe 34. If piston 7 is moved to the left by control 13 seating thereon when the vehicle is moving at a slow speed the pressure on the forward face of piston 7 will be higher than the pressure on the rear face, with the result that pressure in pipe 34 will cause plunger 32 to seat. When pressure in the pump circuit builds up sufficiently by restriction of passage 14, it will act through pipe 17 on the rear face of piston 7 and through pipe 18 to cause plunger 32 to unseat to permit application of brakes 25. In an alternative arrangement, Fig. 2 (not shown), the outlet from valve 22 leads to an accumulator instead of brakes 25, the fluid thus stored being used for subsequent brake operations.
