Filed: 1967-11-07
Abstract: 1,159,289. Assembling bearings. W. KATZ. 7 Nov., 1967 [23 Sept., 1967], No. 50531/67. Heading B3A. [Also in Division F2] A device for inserting ball-bearings 28 in cylindrical or flat bearing spacers comprises a carrier to which the spacer is clamped and a roller 20 rotated in synchronism with the motion of the spacer having recesses 21 to receive the balls and to press them into bores in the spacer. The spacer is made of plastics or other elastic material and resiliently holds the balls. The flat bearing spacer moves tangentially to the bottom 30 of the roller whereas the cylindrical spacer 14a is clamped on a mandrel 14 which is driven in synchronism with the roller by a gear wheel (5), Fig. 1 (not shown), on the drive shaft for the roller meshing with a similar gear wheel (3) on the drive shaft for the mandrel. The spacer is clamped between a fixed collar (11) and a bushing (16) which is moved towards the collar by a handle (19). The roller has recesses corresponding exactly to the bores in the spacer so that the spacer is filled after rotation through 360 degrees.

Abstract: 506,807. Softening water; vitamins; manures. TRIGGS, W. W. (Ellis-Foster Co.) Dec. 3, 1937, No.. 33471. [Classes 46 and 111] [Also in Group IV] Base-exchange materials are obtained by treating water-soluble tannin-like wood extracts in concentrated or dried form with dehydrating, strongly acid agents until they are rendered insoluble. The product is washed and, optionally, dried, ground and graded, for use.. Chestnut extract, sulphited or unsutphited quebracho, cutch, hemlock extract and waste cellulose sulphite liquors are suitable wood extracts. Sulphuric acid, oleum, sulphonic acid, phosphoric acid, phosphoric anhydride, fluosilicic acid, chlor-sulphonic acid, and acid sludge from petroleum refining are suitable dehydrating agents. The preferred temperature range for the reaction is from 50 to 100‹ C. and the reaction is stopped by cooling the mass and pouring it into a large volume of water. The base-exchange capacity of the product is increased by successive exhaustion by hard water and regeneration by means of acid or soluble salt. It, is stated that the products are useful as fertilizers and for concentrating vitamins.

Abstract: 507,007. Cable ends. SOLUTION TRUST, Ltd. Dec. 7, 1937, No. 33838. Convention date, Dec. 7, 1936. [Class 36] The end of an electric cable having one or more conducting cores insulated from a surrounding continuous metal sheath by compressed refractory pulverulent insulating material, such as magnesia, is sealed by means of a solid body of refractory insulating material, an additional quantity of refractory insulating powder being inserted between such body and the cable insulation, thus ensuring the desired dielectric continuity between the cable insulation and the solid body. In the figure a quantity F of insulating powder is introduced into a cavity made in the cable insulation B, and is compressed by applying pressure to the insulating plug E. For ensuring a fluid-tight joint, a metal sleeve C is passed over the sheath C and is closed at both ends by means of gland nuts J, H and metal packings H<SP>1</SP>, J<SP>1</SP>. The nut J also permits the application of end-wise pressure. A nut K and packing K<SP>1</SP> complete the sealing. The added powder may be the same substance as the cable insulation.

Title: Differential Fluid Velocity Sensing
IPC: G01F1/684
Filed: 1966-11-15
Abstract: 1,159,171. Measuring differential fluid-flow electrically. TEXAS INSTRUMENTS Inc. Nov. 15, 1966 [Jan. 21, 1966], No. 51179/66. Heading G1N. [Also in Division G3] The difference in velocity of a fluid flowing in two channels 41, 43, Fig. 3, is measured by a sensor S which comprises a heater H1 of semiconductor material through which a heat conductive metal rod 47 extends, to whose ends flat copper blades 51, 53, situated in the two channels, are soldered. On the free ends of the blades are mounted negative temperature coefficient thermistors TH1, TH2. As the amount of heat conducted along the blades from the heater to the thermistors TH1, TH2 will depend on the temperature of the fluid (arranged to be the same in each channel) and the velocity of the fluid passing over them, the temperature measured by the thermistors will give an indication of the velocity of the fluid in the respective channels. This sensor may be employed in a conventional refrigerator to control the defrosting operation (see Division G3) in response to the build up of frost, one of the channels 43 leading in to the air flow system surrounding the evaporator, the other channel by-passing the evaporator and therefore remaining free of frost. Differences in the temperatures of the two thermistors TH1, TH3, indicating when the channel 43 is becoming blocked by frost, causes initiation of the defrosting operation. The sensor may also be used in a control for balancing the flow of fluid along a pair of ducts in heating apparatus, or may be used to provide an indication that a flow path is obstructed, e.g. a filter blocked.

Continuous internal communication may be established along the assembly by expanding one length by means of pressurized fluid and/or by inserting a mandrel, whereby the adhesive connection causes each wall of the other length to be drawn with the corresponding wall of the first length. Eventually the overlapping end portions become intertwined and intercommunication is established. Expansion may be carried out so the tube is fed on to a mandrel for passage past shirring rollers and compression against an abutment. The overlap length may be 1/5-1/20 of the flattened tube width and the width of the adhesive strip may be at least 3 times the overlap length. The tubing may be of regenerated cellulose and may be paperreinforced.

Abstract: 1,052,670. Moulding sheets; laminates. BALAMUNDI NEDERLAND N.V. Dec. 30, 1964 [Dec. 30, 1963], No. 52779/64. Headings B5A and B5N. [Also in Division C3] A microporous plastic sheet material is produced by mixing thermoplastic resin granules with a plasticizer, arranging a uniform layer of the mixture between two resiliently compressible sheets, and passing the assembly between two hot plates so that the resin granules are sintered into a coherent microporous layer. The distance between the plates diminishes in the direction of movement and the temperature of the plates is such as not to polymerize the plasticizer. The plasticizer is a liquid monomeric compound compatible with the thermoplastic resin and capable of polymerizing to a thermosetting resin when the sintered sheet is subsequently heated under pressure. Both of the compressible sheets may be stripped off after sintering to provide a self-supporting sheet of sintered resin particles, or one or both sheets may be permanently secured in place to provide a two- or three-layer laminate. It is preferred for air to have access to the sintering step which is preferably carried out at a temperature of from 95‹ to 200‹ C. The sintered sheet may be subsequently subjected to heat and pressure to polymerize the plasticizer and form a matrix of thermosetting resin surrounded by the thermoplastic resin, the polymerization being carried out preferably at a temperature of from 115‹ to 175‹ C. under a pressure of from 100 to 2000 p.s.i. in the absence of air, for example by curing in a conventional moulding press. The thermoplastic resin, which may be combined with fillers and pigments or dyes, may be a vinyl resin, for example polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate containing from 85% to 97% by weight of vinyl chloride. The plasticizer may be a diacid ester of a glycol and an unsaturated carboxylic acid and is preferably an acrylic ester, for example ethylene- or a polyalkylene-glycol methacrylate. The weight ratio of resin to plasticizer is preferably in the range 10 : 1 to 1 : 1, for example 3 :1. An inhibitor to inhibit premature plasticizer polymerization and a catalyst for eventual plasticizer polymerization are preferably added to the mixture of resin and plasticizer. The inhibitor, which may be a phenol compound, for example a tri-substituted phenol, and the catalyst, which may be an organic peroxide, for example dicumyl peroxide, are preferably present in proportions of from 0À0025 to 0À1% and from 0À1 to 5À0%, respectively, based on the weight of the plasticized resin composition. The sintering process may take place in apparatus disclosed in U.S.A. Specification 3,067,469.
