Title: Improvements in or relating to door handles for refrigerators and other cabinets
IPC: E05B65/00
Filed: 1934-05-22
Abstract: 429,065. Latches. NORGE CORPORATION, 670, East Woodbridge Street, Detroit, Michigan, U.S.A. May 22, 1934, No. 15250. Convention date, Oct. 25, 1933. [Class 44] The door of a refrigerator or other cabinet has a sliding pin, housed in the door handle or engageable by it, which upon a relatively slight pressure releases the latch and initiates the opening of the door. The door is normally held closed by a swinging latch 58 pivoted in a casing 54 at 60 and engaging a catch formed on a plate 46 adjustably secured to the door frame. The plate 46 is secured to a block 50 having teeth engaging a second block 48, both blocks after relative adjustment being secured by a screw 52. A resilient tube 42 on the door ensures a tight seal when the door is closed and initiates the opening movement of the door when the latch 58 is withdrawn. The latch 58 is connected by a slotted link 72 to a pin 70 carried by links 62 pivoted in the casing 54 at 64, the pin 70 also being connected to a forked member 66 secured to a pin 68 sliding in the upper end of a handle 18. A strong spring 78 normally presses out the latch, but inward movement of the pin 68 moves the links 72, 62 to the position shown in dotted lines and the latch is withdrawn without compressing the spring 78. A wire spring 80 acting between the casing 54 and a bridge piece 82 on the links 62 returns the parts to normal position and in so doing the latch 58 encounters the outside of the catch and further facilitates the opening movement of the door. In its normal position the bridge piece 82 rests against a stop. The pin 68 is engaged by a hinged part 96 in the handle or has a subsidiary handle moulded on its end and projecting from a slot in the handle 18. A modification is described in which the handle is tiltable about vertical pivots and has a laterally projecting lever engaging the end of the pin so that a lateral movement of the handle releases the door.

Abstract: 492,465. Motor - cycle driving - gear. COVENTRY-EAGLE CYCLE & MOTOR CO., Ltd., and WOODMAN, A. C. June 2,1937, No. 15276. Addition to 475,894. [Class 79 (ii)] In a motor-cycle having a pedal crankshaft a with pedal cranks c, a large sprocket wheel d is fixed on the shaft and is connected to a countershaft or the rear wheel hub n, through a chain and a free-wheel sprocket o while a small sprocket e loose on the pedal shaft is connected by a chain to a chain wheel p and is driven from the engine shaft i through a friction clutch g. Thus the rear wheel can be driven from the pedals through one chain and the free-wheel o, or from the engine through the clutch and the other chain. When used to start the engine the pedals drive the clutch member f through the double multiplying gear formed by the two chains. The engine shaft i drives the clutch g through worm gear h, and the clutch can be disengaged by means of an arm controlled by the driver. When the engine is not working it can be disconnected from the road wheels, without disengaging the clutch g, by sliding the pedal shaft to the left to disengage dog teeth e<1> on the sprocket e and the clutch member f. This can be done by the rider pressing his feet against the pedals in the required direction. A spring pin q engages one of two grooves in the pedal shaft and holds it in either selected position. According to the Provisional Specification the engine may drive through a belt instead of a chain.

Title: Improvements in or relating to the manufacture of foamed polyurethane materials
Inventor: BURROWS HAROLD GEORGE
IPC: C08J9/00
Filed: 1963-04-19
Abstract: Foamed polyurethanes may be manufactured by the reaction of an organic polyisocyanate and a predominantly secondary hydroxyl ended polymer containing at least two isocyanate reactive groups per molecule under such conditions that a foam-forming gas is generated and in the presence of a polysiloxane containing at least one organic radical of the general formula <FORM:1081083/C3/1> attached directly to a silicon atom, wherein R represents a divalent hydrocarbon radical containing two aliphatic carbon atoms which may be substituted or wherein the hydrocarbon chain is interrupted by one or more hetero atoms and R1 represents a hydrocarbon radical which may be substituted or wherein the hydrocarbon chain is interrupted by one or more hetero atoms.  In an example an 80:20 mixture of tolylene 2:4 and 2:6 diisocyanates is used as the polyisocyanate, a polyoxypropylene triol obtained by the reaction of propylene oxide with glycerol is used as the hydroxyl ended polymer and water is used as the foam forming agent.  The polysiloxanes containing at least one organic radical of the formula <FORM:1081083/C3/2> attached directly to a silicon atom may be prepared by (1) reaction of a polysiloxane containing silicon bonded hydrogen with an ester obtained from an organic acid and an unsaturated alcohol, (2) reaction of a polysiloxane containing silicon bonded hydrogen with an ester followed by acid interchange with a carboxylic acid of higher b.p. than that present in the original ester, suitably in the presence of catalysts such as dimethyl sulphate, sulphuric acid or trifluoroacetic acid.  The reaction with the unsaturated ester in (1) and (2) is preferably carried out in the presence of a catalyst such as finely divided platinum, platinum on charcoal, chlorplatinic acid and cyclohexene platinous chloride and a solvent, e.g. toluene xylene, dioxane and diglycine.  Numerous examples of suitable polysiloxanes are given.
