Filed: 1951-09-07
Abstract: 696,171. Sewing-machines. UNION SPECIAL MACHINE CO. Sept. 7, 1951 [Sept. 14, 1950], No. 21148/51. Class 112. In order to isolate vibrations due to the rapid contact' with the work or with one another of the work-engaging parts (e.g. presser-foot, feeddog, throat-plate), these parts, or members immediately supporting them, are each formed in two sections with an interposed layer or section of relatively soft and yielding material such as rubber, which may be bonded to the two sections. This construction also gives the advantage that the work-engaging parts of the presser-foot and feed-dog can yield slightly to make contact with the work and to conform with cross-seams or other irregularities in it. In the arrangement shown, the throat-plate 38 is bedded on strips 59, or a gasket, of rubber or the like in a rebated aperture in the work-bed 10 and secured thereto by screws 60 which pass through clearance holes in the plate 38 and have rubber or other vibration absorbing washers under their heads; the work-engaging parts 32, 42, of the presser-foot and feed-dog respectively are attached to their carrying parts 39, 44 through bonded layers of rubber 41, 45; and the shank 44 of the feed-dog is secured in a troughshaped member 48 of rubber in a recess in the feed-bar section 50, being adjustably secured to the latter by a screw 47 passing through a clearance slot in the part 44 and having a rubber washer under its head. The feed-bar section 50 is adjustably connected to the main section 27 by screws 51, 52 respectively engaging a hole and a slot in the section 50. The section 27 of the feed-bar may be divided into two parts connected by a rubber layer. Various modified forms of mounting for the feed dog and presserfoot are described and shown, also a rubbersoled feed-foot.

Abstract: 1,194,492. Tobacco smoke filters. ROBERT L. STRICKMAN FOUNDATION Inc. 3 May, 1968, No. 21206/68. Heading A2C. [Also in Division C3] A filter for aerosols (particularly tobacco smoke) containing as filtering material rigid polyurethane particles essentially devoid of celullar structure. The filter material may be produced by reacting a polyisocyanate and a polyol in amounts sufficient to provide a ratio of reactive isocyanate groups to organic hydroxyl groups of between 0.75 and 1.25 to produce a rigid polyurethane in the presence of sufficient blowing agent that the rigid polyurethane shall be produced as a foam having a density of less than 3 pounds per cubic foot, granulating the resulting rigid foam to produce particles essentially devoid of cellular structure, perferably having a particle size of less than 750 microns, subjecting the granules to a treatment with hot water or steam, and drying the product. It is preferred to employ water-soluble acid salts of metals of groups VA and VIA of the Periodic Table, e.g. alkane tungstates, molybdates, vanadates and chromates and alkyl silicates in the preparation of the intermediate polyurethane foam. The particulate polyurethane filter material is desirably mixed with inorganic additives such as aluminium hydroxide, magnesium trisilicate and carbonates, silicates or hydroxides of alkaline earth metals. These additives may have the same particle size as for the polyurethane particles. Mixtures of aluminium hydroxide and magnesium trisilicate are preferably employed as a 1 : 1 mixture by weight in amounts of between 3 and 15% by weight of the filter material. The dried granules of filter material with or without inorganic additives may be filled into the open tubular end of a cigarette and are prevented from falling out by a small plug of cotton or other suitable material.

Suitable phenolic liquids are cashew nut shell liquid, anacardic acid, cardanol, or ethers thereof, hydrogenated cardanol, esters of cardanol, marking nut shell liquid or Japanese lac.  The liquids may be initially in a polymerized state.  Examples (1) to (3) employ cashew nut shell liquid which has been polymerized to a molasses or syrupy-like state. In example (1) it is dissolved in styrene and heated for 50 hours at 100 DEG  C. to yield a tough, solid, extrudable mass.  In example (2) it is heated in styrene for 16 hours at 100 DEG  C. yielding a thermoplastic non-tacky, soft, rubbery solid which may be milled into rubber.  In example (3) it is dissolved in styrene and heated for 20 hours at 100 DEG  C. yielding a plastic solid which dissolved in toluene, applied to a copper conductor and baked yields a tough, flexible insulation. In example (4), cardanol acetate and styrene heated together yield a rubbery product soluble in toluene to a film-forming solution.  A sample has been furnished under Sect. 2 (5) of a dark brown viscous liquid obtained by heating together styrene and cashew nut shell liquid which has been freed from vericant constituents and metals by treatment with diethyl sulphate and sulphuric acid.
