Title: Weighing-apparatus for use with cranes
IPC: B66C1/40
Filed: 1954-02-24
Abstract: 765,102. Electric measuring systems. AITKEN, R. L. Feb. 23, 1955 [Feb. 24, 1954], No. 5432/54. Class 40 (1).  An electrical load-measuring unit, for inclusion between two parts of a load-bearing member of a crane or like apparatus, comprises a compression member 1 mounted with electrical strain gauges and having an aperture along its compression axis, a tensioned rod 3 (passing through the aperture) attached at one end to one part of the load-bearing member and bearing at its other end on one end of the compression member, and means for applying the load in the other part of the load-bearing member to the other end of the compression member. The tensioned rod 3, attached to the upper part 6 of the load-bearing member through a collar 4 and a nut 5, passes with clearance through the aperture. 2 and bears on the lower end 7 of the compression member through centring members 8, 9. The latter have coacting convex and concave surfaces as shown, and are supported on a nut 10. The load in the lower part of the loadbearing member is applied to the upper end 11 of the compression member through a U-shaped frame 12, a cover 13, a thrust-tube 14, and a thrust disc 15. Keys 17, slotted into cover 13 and into a cover on member 6, prevent rotation of the compression member relative to frame 12 and consequent fracture of a cable 16 carrying the leads to the strain gauges. The collar on member 6 also provides an emergency stop should the rod 3 be fractured.

Abstract: 1414252 Vehicle tyres MONSANTO CO 6 Feb 1973 [7 Feb 1972] 5798/73 Heading B7C [Also in Division D1] A cord of twisted strands of filaments composed of at least 85% by weight of a poly-ester of a dihydric alcohol and terephthalic acid, has said filaments spun from a polymer having a relative viscosity of at least 60, said filaments having a carboxyl concentration of not more than 40 equivalents per million grams, an ether concentration of not more than 3 mole per cent, and an individual filament denier of from 1 to 4. The cords are suitable for reinforcing rubber articles such as tyres. Adhesion between the cords and rubber may be by means of an adhesive, for example an organic solvent solution of a rubber and polyisocyanate; or the cords may be coated with aqueous dispersion of a blocked isocyanate and a latex. Each cord, of the desired size and twist, may be heated under tension to stabilize the cord. The adhesive mixture may be applied prior to the hot tensioning operation so that the adhesive is cured during the heating step. Alternative the adhesive may be applied and dried on the cord in a separate operation. Test results are given for cords made up of three strands each of 1000 denier. The term "relative viscosity" refers to the ratio of the viscosity of a 10% solution of polyethylene terephthalate in a mixture of 10 parts of phenol and 7 parts of 2,4,6-trichlorophenol (by weight) to the viscosity of the phenol-trichlorophenol mixture, measured in the same units at 25‹ C.

Title: Process for the stabilization of organic compounds of high molecular weight
IPC: C08K5/00
Filed: 1949-03-03
Abstract: Halogen-containing polymers of M.W. above 5000 are stabilized by adding at least two compounds, one of which is a diamide of carbonic acid or of the acid derived from carbonic acid by the replacement of the oxygen of the carbonyl group by sulphur or a derivative of such a diamide and the other a compound with two epoxy ethylene groups in the molecule.  Optionally the combination may include an acid-neutralizing inorganic compound, e.g. soda, sodium bicarbonate, sodium hydroxide, calcium carbonate, and magnesium oxide.  Specified diamides are urea, tetra-ethyl urea, phenyl urea, diphenyl urea, thiourea, allyl thiourea, phenyl thiourea and diphenyl thiourea. Epoxy compounds mentioned are 1,3-bis-(21,31-epoxy-11-propoxy) benzene and 2,2-bis-[41(211,311-epoxy-111-propoxy) phenyl] propane. The polymers may be polyvinyl chloride, polyvinylidene chloride, copolymers of vinyl chloride and vinylidene chloride, and after-chlorinated polyvinyl chloride. In an example, polyvinyl chloride is made by polymerizing vinyl chloride in aqueous emulsion using sodium mersolate (obtained by treating hydrocarbon fractions of 10-20 carbon atoms per molecule with sulphur dioxide and chlorine and saponifying the product) in the presence of potassium persulphate as catalyst at a pH of 8, and the polymer coagulated with amyl alcohol.

Abstract: 1,074,416. Shovel excavators. CESSNA AIRCRAFT CO. Feb. 10, 1966 [Aug. 2, 1965], No. 5962/66. Heading E1F. [Also in Division F1] As the piston (22, 27) of a hydraulically actuated motor operating e.g. the boom of a mechanical shovel or back hoe, Fig. 4 (not shown) approaches the end of its stroke in a cylinder (10), a slide (14) carried by the piston (22, 27) co-operates with the cylinder wall surface surrounding a side wall port (30) to progressively decrease the flow of fluid being discharged therethrough to thereby smoothly decelerate the piston. The slide is provided with an elongated groove (35) on its external surface which co-acts with the port (30) to provide a variable restriction. The groove (35) may be of constant width but gradually decreasing depth, or of gradually decreasing width but either constant on decreasing depth. Alternatively, the groove may be replaced by a series of aligned holes of gradually decreasing diameter. The slide (14) is a loose fit in the cylinder (10) and is attached to the piston by pins (17, 19) disposed in radial slots in the piston. A compression spring (20) disposed between the pin (19) and the slide urges the slide into contact with the side of the cylinder in which the port (30) is located. When the piston is to be moved in the opposite direction, pressure fluid entering the port (30) displaces the slide against the action of the spring (20) to provide a larger inlet flow passage.

Abstract: 622,021. Grinding and polishing. HENDERSON, A. S. March 3,1947, Nos. 5997 and 27281. [Class 60] [Also in Group XXII] A tool for boring cylinders comprises a tubular carrier and locating member A adapted to be attached at one end in centred relation to the end of the cylindrical part B to be bored, a detachable tubular guide C adapted to be fixed in the outer end of the carrier, an operating bar F which can slide in the axial direction and be rotated within the guide member by manual or other power, one or more tools mounted in the end of the bar, and means for automatically feeding the bar in the axial directions as it is rotated. The tool may be located by means of a cylindrical body having a frusto-conical end which is adapted to engage both the carrier A and the cylindrical part being bored; in this aligned position, the carrier A is bolted to the work. The guide member C is provided with a flange C<SP>1</SP> which rests in an annular recess A<SP>2</SP> in the carrier and the two members are connected by bolts A'. The operating bar F is rotated by a hand-crank P through bevel gears R, G and is journalled at its upper end in a plate L on which is mounted a gear train to drive a lead screw N in threaded engagement with a nut D secured in the guide member. The plate L also supports a guide rod 2 free to slide in the guide member. The gear train which rotatably couples the lead screw with the operating bar comprises a shaft O<SP>2</SP>, Fig. 6, displaceable in a slot in the plate L so that the lead screw may be rotated by the handcrank P to withdraw the tool from the work at the end of the operation. Alternatively, the nut may be made in two parts so that it can be disengaged from the lead screw. The polishing head, Fig. 8, carries two strips of abrasive material which are wrapped around the outer surfaces of two spring members S, T, each of which comprises two curved plates, such as T, T<SP>1</SP>, between the ends of which the abrasive material is clamped. The polishing head may be replaced by cutters (see Group XXII), and the guide rod 2 by a second lead screw. In an alternative construction, the lead screws are secured to the plate L and the nuts rotated. Change gears may be provided to enable the operating bar to be rotated at a higher speed without increasing the rotational speed of the power source and a higher rate of feed obtained by using lead screws of greater pitch.
