Abstract: 928,500. Determining physical qualities. UNITED STATES STEEL CORPORATION. Oct. 10, 1961 [Oct. 26, 1960], No. 36348/61. Class 37. In a method and apparatus for determining the magnetic properties of travelling steel strip 10, a yoke 33 having outwardly projecting polepieces 33a and carrying energizing and pick-up windings 34, is arranged to be presented intermittently into close adjacency with the strip, and the current in the pick-up coil is measured. The yoke is mounted on a sector of a cylinder 20 journalled in a measuring housing, and guiding rollers are provided to ensure that the strip passes partially around the measuring drum. Constructional details of the drum are described with reference to Figs. 2 and 3 (not shown) and in an alternative embodiment described with reference to Fig. 4 (not shown) a number of yokes mounted in the same sector of the drum are provided, at least one of which is provided with projecting polepieces lying longitudinally of the drum. The currents are conducted to and from the windings by slip rings 36, the required properties being determined in a computer 37 to which width and thickness signals are supplied from transducers 38, 39.

Patent GB-984300-A (GB)
Title: Polyurethane foam product and method of making same
IPC: C08J9/40
Filed: 1962-09-25
Abstract: Open-cell polyurethane foams are stiffened by impregnating the foam in an organic polyisocyanate or solution of organic polyisocyanate and thereafter drying the product.  The foam may be first impregnated with a weakening agent, e.g. caustic soda and mechanically worked to weaken its cell wall structure.  The product may have a density in the range 0.75-2.4 pounds per cubic foot, and may be coated after stiffening with an organic coating composition, e.g. resins, waxes or rubbers which covers the internal and external cell surfaces. At least one defined region of the foam may have a rigidity substantially in excess of that of the remainder, obtained by restricting the action of the polyisocyanate to a defined region of the foam by masking. Preferred polyisocyanates are arylene diisocyanates, e.g. the toluene diisocyanates.  After treatment any excess polyisocyanate may be removed by evaporation at 20-40 DEG  C. or by heating to 160 DEG  F. or reduced pressure.  Plasticizers, e.g. cresyl diphenyl phosphate, tricresyl phosphate; dibutyl phthalate; di-(2-ethyl hexyl)phthalate; diethyl, dibutyl and polypropyl adipates may be added to the polyisocyanate.  Solvents may be aliphatic hydrocarbons, chlorinated hydrocarbons, ketones and aromatic hydrocarbons. In examples, polyurethane foams derived from polyethers and polyesters were repeatedly compressed in polyisocyanates at room temperature for 1-5 minutes and were then airdried.ALSO:Polyurethane foams (which have been stiffened by immersion in an organic polyisocyanate followed by drying (see Division C3), are coated on their internal and external cell surfaces with an organic material, e.g. ethyl or nitro cellulose, chlorinated rubber, and coumarone, epoxy, polyethylene, fluoroethylene, furan, melamine, phenolformaldehyde and hydrocarbon resins, also synthetic rubbers, silicones, urea formaldehyde resins and polymers of styrene, vinyl chloride, vinyl chloridevinyl acetate, terpenes and waxes.  The coating compositions are applied to the stiffened foam by immersing the foam in a solvent containing the coating composition and compressing and decompressing till saturation occurs.  Plasticizers may be included in the coating composition.  In an example a stiffened polyurethane foam was coated with a solution of a polyvinyl chloride-polyvinyl acetate copolymer in tetrahydrofuran.

Title: New or improved regulating arrangement for internal combustion engines of motor vehicles

Filed: 1958-11-17
Abstract: 874,522. Clutch control. DAIMLERBENZ A.G. Nov. 17, 1958 [Nov. 15, 1957], No. 36944/58. Class 80 (2). Engagement of an automatic separating clutch 12 between an engine-driven hydraulic coupling 11 and a change-speed gear 13 on a motor vehicle trips a switch 26 which through relays 29, 25 moves a valve member 21 whereupon torque-increasing additional fuel and air is admitted, independently of the normal fuel control, to the engine 10 to prevent clutch shock. Injection or carburetter engines may be so controlled. In Fig. 1, engaging movement of the clutch 12 is transmitted through a member 27 and spring 28 to close the switch 26 which, provided the switch 30 is closed (i.e. a gear is engaged), completes the circuit of the relay 29 to energize the relay 25 which moves right, against a spring 22, a piston 21 opening a port 19 which admits additional air to the induction manifold, the pressure change in which acts on a pneumatic governor 16 of a fuel pump 15 to supply additional fuel to the engine. When the clutch is disengaged the piston is returned by the spring 22 cutting-off this additional fuel supply. The air opening 19 may be an adjustable nozzle or interchangeable nozzles of different sizes may be used. The timing of the opening of the switch 26 may be adjustable which adjustment may be simultaneous with the clutch adjustment. In Fig. 2 (not shown), the inlet is opened by the spring 22, the air passing through bores in the piston and closed by energization of the relay 25 (Fig. 1), on de-energization of the relay 29 (Fig. 1).

Abstract: 1403781 Binding particulate material FOSECO INTERNATIONAL Ltd 28 March 1973 [4 April 1972 9 Aug 1972] 15443/72 and 37218/72 Heading C3N A process for the production of bonded particulate material comprises mixing together the particulate material, an aqueous alkali metal silicate solution and a hardener consisting essentially of a liquid unesterified polyhydric alcohol miscible with the aqueous alkali metal silicate solution and a fully esterified ester of a polyhydric alcohol. Suitable liquid unesterified polyhydric alcohols are glycerol, ethylene glycol, diethylene glycol and triethylene glycol. Suitable esters are esters of the aforementioned polyhydric alcohols having esters derived from carboxylic acids such as acetic, propionic and butyric acids, e.g. ethylene glycol diacetate. The amount of hardener may be 5-20% by weight of aqueous alkali metal silicate or expressed differently 0À1-0À8% by weight of the total moulding composition. The weight ratio of polyhydric alcohol to fully esterified polyhydric alcohol is preferably 1 : 12-1 : 1. It may be desirable to add a mutual solvent for the fully esterified polyhydric alcohol and the unesterified polyhydric alcohol and this may be a polyhydric alcohol, e.g. hexylene glycol or isooctyl alcohol or methylisobutyl carbinol. The alkali metal silicate is preferably sodium silicate of SiO 2  : Na 2 O ratio 2À2-3À5 : 1. The hardener may also contain a minor proportion relative to the fully esterified ester of one or more partially esterified esters of a polyhydric alcohol, e.g. glycerol diacetate or ethylene glycol monoacetate. The hardener may take the form of a two-part pack, the ester being in one package and the aqueous alkali metal silicate solution being in the other. In such a two-part pack the liquid unesterified polyhydric alcohol may be contained in both packages.

Title: Process for the preparation of 2,2-dimethylalkanoic acid esters
Filed: 1962-10-02
Abstract: Esters of 2,2-dimethylalkanoic acid are prepared by contacting an isobutyric acid ester with a terminal olefinic monomer of formula CH2=CR1R2, where R1 and R2 are hydrogen atoms or alkyl groups in the presence of a telomerization catalyst at a pressure of 400 to 3000 p.s.i.g. and a temperature of 50 DEG  to 400 DEG  C.

Title: Record changer
IPC: G11B3/085
Filed: 1976-09-09
Abstract: The switching-over device allows reliable switching-over from change mode to automatic play mode with just a few components. The functions of the stack spindle (1) are controlled from below by means of pressure sleeves (3, 5). A command disc (13) controls the pick-up arm movements and raises the pressure sleeves (3, 5) via command levers (15, 17) for controlling the stack spindle (1). In a changing operation, the command lever (15) presses the pressure sleeve (5) upwards. In so doing, a slide (49) is pushed to the right via a tipping lever (35) and a driver pin (43). A blocking pin (57) of the pick-up arm mechanism is thereby released, so that the pick-up arm can swing over the newly placed-on record. When the last record has been ejected, the command lever (15) can perform only half a stroke upwards. In this case, the displacement is not sufficient to push the slide (49) far enough to the right. In this case, the slide (49) blocks the pick-up arm mechanism. <IMAGE>
