Title: Improvements in or relating to An Electrically Driven Refrigerator Motor/Compressor Unit
IPC: F16F15/067
Filed: 1966-09-26
Abstract: 1,150,915. Compressors. DANFOSS A, S, Sept.26, 1966 [Oct.16, 1965], No.42876/66. Heading F1N. [Also in Division F2j A motor driven compressor unit 3 is resiliently mounted within an outer casing 1 by means of a plurality of springs 8 each having a stiffness which increases as the load increases, due to abutment of part of the spring against a stop. As shown, each spring 8 is a conically wound spiral having its inner end secured to a bracket 10 and its outer end secured to a cup 13 carried by the unit. If a spring is loaded axially, each coil thereof in turn abuts the bottom stop of the cup 13 thereby progressively increasing the stiffness. Similarly if a spring is loaded radially the outer coils abut the inside of the cup 13. To ensure that the coil turns are concentric when supporting the unit, the inner end is offset in the unloaded condition. The springs may be located at the sides, top, or bottom of the unit. In an alternative construction Figs. 5 and 6 (not shown), each spring is in the form of a spring wire cantilever (22), which when displaced sideways, engages a rounded plate (27) which thereby reduces its effective length and thus increases its stiffness.

A multi-speed cycle hub has a planet carrier 5 fast with a driving sprocket 3 and connected to the hub 2 by a ratchet clutch 11 for direct drive. The planets mesh a stationary sun 8 and a ring gear 9 which is connected to the hub 2 by a ratchet clutch 15 for high ratio drive, the pawls of the ratchet clutch 15 being retained out of engagement with the ratchet during direct drive by a portion 20 of a control sleeve 19 engaging arms of the pawls. The control sleeve is shifted axially, against the bias of a spring 21, by centrifugal weights 16, which in the embodiment shown are driven directly by the planet carrier. In a modification the weights are driven from the carrier through step-up gearing. In either case the construction ensures that the centrifugal weights are not driven during freewheeling.

Abstract: 1451728 Dry shavers SPERRY RAND CORP 4 Oct 1974 [8 Nov 1973] 43135/74 Heading B4B [Also in Division B3] A method of making a landless inner cutter for an electric shaver comprises removing material from a strip 44 of metallic material to provide the strip with a first transverse archlike edge 70, Fig. 7, in the plane of the strip and between side edges of it, cutting the strip to form a second transverse archlike edge 70A in the plane of the strip, the edges 70, 70A, forming an arch-shaped blade section 18 in the strip, bending the blade section so as to move it substantially normal to the plane of the strip and repeating the cutting and bending steps. The strip 44 is formed with leg portions 22 along either edge and the blade sections 18 are formed in the flat central portion of it. A reciprocating tool 45 cuts the successive archlike edges, 70, 70A in co-operation with a die 46. The tool is formed with an arch-shaped surface 51 and a slanting cutting and bending surface 54 and the die is provided with a retractable insert 49 about which the blade sections are bent. The initial archlike edge 70 is formed either by the tool 45, in which case an area bounded by the edge 70, a tab 64 and side portions 74A, is cut and bent and subsequently removed or it may be formed, e.g. by grinding. The formed strip is cut to length and a supporting portion 14 is engaged with the blade sections 18, for welding thereto.

Title: Cellular foamed articles from thermoplastic alkenyl aromatic polymers
IPC: C08J9/00
Filed: 1960-12-21
Abstract: Cellular thermoplastic polymers are made flame-resistant by incorporating in them an organic halogen-containing flame-proofing agent and, as a synergist, an indigo compound.  The polymer is either (a) an alkenyl aromatic polymer (e.g. styrene, alpha-methyl styrene or a nuclear halogenated or alkylated derivative thereof) or a copolymer thereof with up to 50% of another monomer (e.g. acrylonitrile) or (b) a copolymer of 1-97% by weight of methyl methacrylate and 99-3% by weight of an alkenyl aromatic monomer. The flame-proofing agent is preferably a brominated aliphatic, cycloaliphatic or alkylaromatic hydrocarbon or aliphatic ether or ester (e.g. propionate or phosphate) containing at least 45% by weight of bromine.  The indigo compound is preferably indigo white or an indigo derivative of formula: <FORM:0950292/C3/1> where R is an -NH- group or -S-; X and Y are hydrogen, halogen or lower alkyl; and Z is hydrogen, halogen or a radical of formula-SO3M where M is hydrogen or an alkali metal.  The foamable composition may also include a hydrobromic acid acceptor (e.g. sodium acetate, magnesium oxide, magnesium hydroxide, zinc oxide, calcium oxide, calcium carbonate or sodium bicarbonate) or a surfaceactive agent (e.g. a sodium alkyl sulphonate, sodium lauryl sulphate or an alkyl phenyl polyethylene glycol ether) which latter may be added together with the indigo compound. The foam may be made by (1) feeding the granular polymer to a first section of an extruder where it is heated to about its melting temperature and forwarded through a sealing plate or disc into (2) a second section where it is mixed with a volatile liquid (e.g. an aliphatic hydrocarbon, ether or alhogenated hydrocarbon) and fed into (3) a mixing section where it is agitated and cooled and forwarded to a (4) a mixer cooler where the ingredients are thoroughly blended, brought to a uniform temperature between 60 DEG and 130 DEG C., under pressure, and (5) extruded into a zone of lower pressure (e.g. the atmosphere) to cause expansion of the extruded material.  As an alternative to step (4), the extruded product may be quickly cooled and then crushed or ground to form latent foaming granules. The flame-proofing agent and the indigo compound may be added at any point prior to extrusion. Examples describe the production of polystyrene foams.

Abstract: 1,240,129. Self-leveling suspensions. V. LANGEN, [trading as LANGEN & CO.]. 17 Sept., 1968, No. 44133/68. Heading B7D. [Also in Division F2] The liquid filled cylinder space 11 of a pistoncylinder vehicle suspension unit is connected to a hydropneumatic accumulator 22 and connectible both to a pressure liquid source such as a pump 18 and also to an exhaust line T. A valve element 8 is so connected between the piston 4 and the cylinder head 2 that both the pump P and the line T are normally isolated from the space 11. However on excessive inward movement of the piston 4, the space 11 is connected to the pump and on excessive outward movement to the exhaust, so that the suspension unit is self levelling. The means controlling the valve movement are a spring 16 and some means, such as a second spring 12, in the cylinder head. The latter means is constantly acting on the valve element whereas the spring 16 acts or does act in accordance with the piston position. The initial spring loading on the valve may be adjustable. In the form shown the spring 12 is inside a chamber 19 which communicates via a constricted passage 20 with the cylinder space 11. In Fig. 2 (not shown) the parts controlled by the valve element 8 are arranged slightly differently from the Fig. 1 arrangement and the spring 12 is dispensed with, its function being performed by hydraulic pressure in the chamber 19 acting on the valve element.
