Title: Refrigerating plant of the absorption type
IPC: F25B49/04
Filed: 1938-01-27
Abstract: 506,846. Refrigerating. AMUNDSEN, I. Jan. 27, 1938, No. 2681. Convention date, Jan. 27, 1937. [Class 29] Absorption machines and systems. - The generator-absorber of. a reversing machine is heated by vapour evolved, during the generation periods, in a continuously-heated body or accumulator. Thus, the generator-absorber 1 packed with, e.g. active carbon, is provided with a heating and cooling jacket 14 the upper and lower ends of which are connected through pipes 25 and 13, 11, 19 respectively with the corresponding ends of a vapour generating duct 24 in a cast iron block 20 heated by a gas burner. The upper end of the pipe 11 forms the seat of a non-return valve 12 and is connected to a water tank containing the refrigerant condenser 3, while the lower end of the pipe, which is closable by an electromagnetically operated valve 15, communicates with a water outlet pipe 16 and a pipe 18 having a branch 19 to the duct 24 in the block 20 and another to an open-ended pipe 21 having a branch 22 to the outlet pipe 16. The jacket 14 of the generator-absorber is provided with an outlet pipe 26 connected to an open-ended standpipe 27 and having a cast iron heat accumulator sleeve 30 for prolonging the heating period of the generator-absorber and carrying a bimetallic strip 31 coacting with the arm 32 of a tiltable mercury switch 33 controlling the current supply to the solenoid'39 of the valve 15. During the generating period, refrigerant vapour, e.g. methylalcohol, passes from the generatorabsorber through the pipe 2 to the condenser from which the condensate passes via a short tube provided with a float needle valve 6 into the evaporator 7. At the same time cooling water from the jacket 14 flows through the pipe 13 and the lower end of the pipe 11 into the pipe 18 and thence to the duct 24 the vapour evolved in which passes through the pipe 25 to the jacket. A part of the vapour flows into the pipe 26 thus heating the sleeve 30 and the bimetallic strip 31 which tilts the switch 33 thus completing the circuit through the solenoid 39, raising the valve 15 to close the end of the pipe 11 and, through a rod 17 carried by the valve, opening the valve 12 and permitting cooling water to flow from the tank through the pipes 11, 13 into the jacket. This initiates a period of absorption during which refrigerant vaporizes in the evaporator 7 and returns'via a tube having at its upper end a non-return valve 5 to the generator-absorber. During this period, the block 20 warms up and at a predetermined temperature the contact thermometer 38 completes the circuit through the switch solenoid 37 and, through the armature 36, tilts the switch back to the position shown. An expansible rod may be substituted for the thermometer, and the bimetallic strip may be replaced by a vessel containing a vaporizable liquid. In a modification, the block 20 may bo heated from the heat accumulator 40, Fig. 2, of a stove burning coke.

The lighter has a lid 3 pivoted to an inner casing 2 by a hinge 4 having a plate 6 extending to form a cup 7 engaged by an upper nose 11 on a cam 8 pivoted on a pin 9. A lower nose 12 on the cam bears against a spring plate 13 secured to the plate 15 by the rivet 27. When the lid is opened the cam 8 is carried through a dead-centre position by the cup 7. An outer casing 1 fits slidably over the inner casing 2. Fig. 2 (not shown) shows a gas-filled lighter in which a leaf spring riveted to the cup operates a gas valve, above which is a hollow burner extending through a hollow rivet in the plate. The fuel reservoir is held in position in the inner casing by dimples in the inner casing which engage grooves in the walls of the reservoir.

Title: Process for the production of polymeric materials
IPC: C09D151/00
Filed: 1959-01-30
Abstract: A copolymer of a C1-C4 alkyl acrylate or methacrylate ester and an ethylenically unsaturated carboxylic acid, e.g. acrylic or methacrylic acid, is used to esterify some of the hydroxyl groups contained in the partial esters of a polyhydric alcohol and the acids of non-drying oils, e.g. castor or hydrogenated castor oil, and the uncombined hydroxyl groups of the partial esters are thereupon esterified with a polybasic acid, if desired in the presence of a further amount of polyhydric alcohol.  The products may be mixed with a polyepoxide to provide curable coating composition.  In the example, a methyl methacrylate-methacrylic acid copolymer is esterified with the reaction product of hydrogenated castor oil and glycerol, and the product further esterified with a mixture of phthalic anhydride and glycerol and then mixed with an epoxy resin and cured by heating at 160 DEG  C. in the presence of an aliphatic amine as a catalyst.  The copolymer of the above example may be replaced by copolymers of other C1-C4 alkyl acrylates and methacrylates or mixtures of such esters, and other polycarboxylic acids, e.g. isophthalic and adipic acids, may be employed.

Title: Electrical railway-switch operating mechanism

Filed: 1927-02-07
Abstract: 265,962. Bachmann, C., and Kraft, R., (trading as Scheidt & Bachmann), Feb. 12, 1926, [Convention date]. Electric operation. - In electrically-operated railway points, wherein a reversible motor 1 drives a drum 5, Figs. 1 and 3, by gearing 2 - - 4, the expanding friction ring 6 is applied to the drum by a U-shaped leaf spring 7 with sufficient force to break a frangible connection in the operating-rod when movement of the points is obstructed, and hence actuate the motor cut-off. The driven disc 8, carrying the operating-pinion (not shown), is driven by the contact of the spring 7 with a lug 10 or 11, according to the direction of rotation. After the motor circuit has been broken, the parts are brought to rest by engagement of a lug 12 on the disc 8 with an initially-stressed U-shaped spring stop 14, normally bearing on fixed lugs 15. When either limb contacts with a central lug 15<1>, residual momentum of the motor is absorbed by slip of the coupling. Fig. 4 shows a modification wherein the friction ring is omitted, the driving- spring carrying blade springs 16, 17 normally pressing against lugs 19, 20, one spring drivably engaging a lug 10 or 11 on the driven disc 8, which carries a stop lug 12 as before. Momentum is absorbed by yielding of the engaged spring.
