Abstract: 974,489. Fusible cut-outs. LITTELFUSE Inc. Dec. 8, 1961 [Dec. 12, 1960], No. 44047/61. Heading H2G. In a fuse of the type which breaks a circuit on low overload by separating a heated soldered joint and on high overload by fusing a filament, a support is provided for the fuse assembly to relieve the filament of strain. In the arrangement shown in Fig. 1, the support is constituted by a good electrical but poor heat conducting strip 10, e.g. of an alloy consisting of 55% copper and 45% nickel, which is soldered at 42 to a copper heat reservoir 22 around part of which is wound heater coil 29, one bared end 33 of which is joined to the other terminal and constitutes the high overload fuse. The other bared end 40 is soldered at 42 to the members 22 and 10. When the solder softens after continued low overload spring 46, compressed between a shoulder on the heat reservoir and a mica sheet 52, separates the members 10 and 22 and the circuit is broken. The housing 4 is of glass having end caps 6 which form fuse terminals one of which is soldered to the strip 10 and the other to the fuse filament, the latter having a further coat of insulating material 36 to prevent high-voltage arcing between the fused filament and the terminal. In a further embodiment (Fig. 6, not shown), a rubber block is provided to support the heat reservoir at the opposite end from the strip which acts as a leaf spring to separate the softened solder joint.

Title: Improvements relating to cellular polystyrene materials
Inventor: NEWNHAM JOHN LEATHFM MATTHEW
IPC: C08J5/12
Filed: 1961-12-27
Abstract: A rigid cellular material consisting of polystyrene is made by expanding bodies of a polystyrene composition and bonding these together by means of a non-cellular bonding agent, wherein the bonding agent sets sufficiently slowly to allow preferential accumulation of the bonding agent at the points of contact of the expanded polystyrene beads. Such a bonding agent may be a non-foaming liquid polyurethane-forming composition.  A secondary bonding agent such as a latex binder, a liquid mixture of plaster and water or cement and water or a liquid polyurethane rubber (each exemplified) may be used to treat the bonded polystyrene material. The weight ratio of expanded bodies to bonding agent may be 7:1 to 1:10 (respectively) but preferably 3:1 to 1:5.  The polystyrene bodies which may be derived from a thermally-expandable composition containing pentanes, may be intimately mixed with bonding agent in a mixer. Specific embodiments disclose moulded articles e.g. bricks, in which non-adhering materials (specified) may be used to line the mould, another embodiment is a plywood-foam laminate. The polystyrene beads used may be twice expanded. Additives to the latex binder include potassium oleate, sulphur, zinc diethyl dithiocarbamate, zinc mercaptobenzthiazole, zinc oxide, N,N1-di-b -naphthyl-p-phenylene diamine, sodium silicofluoride, zinc oxide, casein, potassium hydroxide and whiting. If a polyurethane-forming composition is used then the beads of polystyrene may be moistened with water to obtain faster bonding. If a liquid polyurethane rubber is used as a secondary bonding agent, then trimethylol-propane may be added.  The non-forming liquid polyurethane-forming composition which may be used as a bonding agent, is a mixture of one or more organic compounds having at least 2 -NCX radicals (X=O or S) e.g. tolylene diisocyanate or diphenylene methane diisocyanate, and one or more organic compound having at least 2 active hydrogens e.g. polypropylene glycol triol or polyether tetrol derived from polypropylene oxide, ethylene diamine and ethylene oxide; this mixture may be catalysed by stannous octoate.
