Title: Process for the preparation of oxidation products of propylene
IPC: C07C/
Filed: 1962-10-09
Abstract: Oxidation products, consisting substantially of propylene oxide and acetaldehyde are produced by the oxidation of propylene with oxygen the reaction-components being conducted at elevated pressure and high flow velocity through a pre-heating chamber where they are heated to a temperature of 250 to 350 DEG C., the flow velocity being so adjusted that no substantial oxidation takes place in this chamber, and the reaction mixture then being conducted into a reaction chamber where the flow velocity is reduced so as to effect oxidation. Preferably a small quantity of water or steam is added to the reactants supplied to the pre-heating chamber.  The oxygen used may be supplied in the form of air and the reaction gases may contain other components, for example, nitrogen, carbon monoxide, carbon dioxides or propane. Preferably the flow velocity in the preheating chamber is about 3 to 30 times greater than that in the reaction chamber. Specifications 643,687 and 718,603 are referred to.

Title: Polyurethane resins
Inventor: SCHMELZER HANS-GEORG
IPC: C08G18/10
Filed: 1965-09-08
Abstract: High molecular weight polyurethane resins are prepared by reacting together polyisocyanates and polyhydroxyl compounds in which at least a part of the polyhydroxy compounds are polymethylenes having alcoholic hydroxyl groups and a molecular weight of 500 to 4000.  The proportion of polyoxymethylene to other polyhydroxyl compounds is preferably from 5 to 40 parts per 100 parts other polyhydroxyl compounds, while the polyisocyanate e.g. toluylene diisocyanate is preferably present in excess.  In a modification polyurethane masses made from polyhydroxyl compounds polyisocyanates and, if desired, chain lengthening agents are cross-linked with further polyisocyanates and polyoxymethylenes having alcoholic hydroxyl groups and a molecular weight of 500 to 4000.  In examples an adipic acid-ethylene glycol polyester (OH number 56) is reacted with a polyoxymethylene containing OH groups, and a mixture of (a) toluylene diisocyanate-(2:4) and (b) toluylene diisocyanate-(2:6), or with (c) 4,41-diphenyl methane diisocyanate or a mixture of (a) and (c)-variations, e.g. the use of a mixed polyester of adipic acid, ethylene glycol and 1,4-butane-diol or of adipic acid-1,6-hexene diol-polyester are given.  Other examples of reaction of such polyoxymethylenes with (15) 1,6-hexamethylene diisocyanate or (16) 1,6-hexamethylene diisocyanate and 1,4-butane diol are also given.

Title: Rotary motion coupling device
IPC: F16H57/00
Filed: 1963-09-30
Abstract: 996,932. Slip couplings. PEUGOT & CIE. Sept. 30, 1963 [Dec. 20, 1962], No. 38461/63. Heading F2U. An element of plastics material has a smooth cylindrical surface fitting frictionally on to a smooth cylindrical ground surface of a co-operating member, torsional overload causing the element to slip relatively to the member. The plastics material may be nylon &c., and is chosen to have a larger coefficient of thermal expansion than that of the co-operating member. Thus, the heat produced by prolonged slipping causes greater expansion of the plastics element than of the member, and reduces the frictional forces between the two. In one form, a gearwheel 1, Fig. 1, of plastics material, has a cylindrical ribbed hub fitting frictionally upon the ground, cylindrical and circumferentially grooved surface 5 of a shaft A. The plastics gear-wheel 1 meshes a gear 2 on a shaft B. Under normal load conditions, the friction between the shaft A and the plastics gear-wheel 1 transmits drive. On overload, the shaft A slips within the plastics gear-wheel 1. The ground surface 5 of the shaft A may be of smaller diameter, Fig. 2 (not shown), to cooperate with a correspondingly smaller hole in the plastics gear-wheel. Axial grooves, Figs. 3-6 (not shown), may be provided in the hole through the plastics gear-wheel. As applied to a slipping shaft coupling, a sleeve 9, Fig. 7, of plastics material grips fast the knurled end 10 of one shaft B and engages frictionally with the cylindrical end 7d of another shaft A. To determine the torque loading necessary to produce slipping, a detent V, Fig. 8, is engaged with the plastics gear-wheel 1 and varying masses P are applied to the end of a lever clamped to the shaft A.

Abstract: 928,341. Gear pumps. BORG-WARNER CORPORATION. Nov. 16, 1959 [Nov. 28, 1958], No. 38799/59. Class 110 (2). [Also in Groups XIII and XXIX] In a closed, circulating liquid cooling system (see Group XIII) containing a gear pump comprising intermeshing gears 35, 36, excess pressure in the pump outlet line K is relieved by connecting it directly through a spring-biased pressure-relief valve (Fig. 4, not shown), to the pump inlet duct D, thus by-passing the pump. The relief valve assembly (not shown) is attached to or forms part of an end plate secured to the pump housing 24 by bolts 50 and co-operating with the housing to provide cavities for the gears 35, 36. The pump inlet line also includes a device Q which acts to maintain a steady flow of fluid to the pump. The device Q comprises a chamber 47 containing a bellows 48 which is caused by any sudden fluid surge, to contract so that fluid flow is retarded due to the consequent increase in the effective volume of the fluid flow path in the chamber 47. On a decrease in fluid pressure the bellows expands to diminish the flow volume and hence increase the rate of flow.

[Class 40 (iv).] In an acoustic instrument such as a telephone transmitter a diaphragm or like damping device comprising a pile of thin leaves is formed by folding and interleaving a number of strips of paper or like material. In the construction shown two strips AB, CD, Fig. 1, are initially placed at right-angles one resting on the other, the lower strip CD is then folded about the line XX over the upper strip AB; then the strip AB is folded over the upper portion of the strip CD and so on until a pile of the required thickness is obtained. The protruding edges are trimmed and the pile placed in a press, in which the edges are cut to the desired shape, e.g. as shown in Fig. 5, and a hole punched through the centre. Thus in the finished device alternate leaves are hinged together with the hinges on one strip at right-angles to those of the other strip so that relative rotation of the strips is prevented, while, if the pile is extended as shown in Fig. 6 the hinge lines substantially form a helix. In assembling the device within a telephone transmitter of the kind having a removable capsule, one end-ring or leaf is secured to the diaphragm and the opposite end-ring to the seating of the capsule.

Title: The electrothermic production of carbon monoxide by fluidized bed techniques
IPC: C01B32/40
Filed: 1957-02-25
Abstract: A bed of finely divided carbon particles is fluidised by the upward passage therethrough of carbon dioxide, the fluidised bed being heated by passage of electric current therethrough to a temperature which sustains a reaction between the carbon dioxide and the carbon particles thereby producing carbon monoxide, which is recovered from the outgoing gases.  The fluidised bed occupies a volume 10% more than the bed before fluidisation and is maintained at above 600 DEG C., e.g. 800-1200 DEG C.  The particles may be fluid petroleum coke obtained in a fluid bed petroleum coking process and are calcined, or may be metallurgical or Stoker coke. The time of contact between the gas and particles is 0.5-4 seconds.  The carbon particles may be impregnated with a catalyst, which is an alkali metal hydroxide or carbonate, e.g. 2-4% of sodium hydroxide applied in aqueous solution. D.C. or A.C. is supplied to the bed by a plurality of electrodes which spread the heat evenly. Thus two graphite electrodes may be inserted from above into the bed, or a single axial electrode co-operating with the wall of the container as the other electrode may be used. The carbon particles may be treated before impregnation with the catalyst by a low temperature oxidation process, e.g. by fluidising the carbon in a stream of air at 325 DEG C. for four hours.  Specifications 638,719 and 768,909 also are referred to.
