Title: A device for the measurement of torque
Inventor: PRESTIDGE ALLEN FRANK
IPC: G01L3/14
Filed: 1961-05-02
Abstract: 939,175. Measuring torque electrically. AUTOMOTIVE PRODUCTS CO. Ltd. May 2, 1962 [May 2, 1961], No. 15860/61. Class 40 (1). A torque measuring device comprises a coupling between two parts of a drive-shaft and incorporates spoked portions 4 through which the drive is transmitted and the resultant strain in which is measured by resistance strain gauges 12. The coupling comprises a hub portion 1 integrally formed with a flange 2 and bolted to a flange 5, both flanges being bolted to the shaft portions. The spokes 4, formed by machining out gaps 3, are provided with overload stops 14 which each comprise a reamered hole 31 central in the remaining hub portion, and from the top and bottom of which saw cuts 32 extend tangentially in opposite directions. Each hole 31 contains a pin 33 located by stop-pin plates 34. The pins 33 are a smaller diameter than the holes 31 and thus form a peripheral gap which closes on the occurrence of an overload. Connections to the strain gauges 12 located on each side of the spokes 4, pass through a passage 11 and terminate at four slip-rings 7, each having two silver graphite spring-loaded brushes 8 spaced angularly one from another and located in a cylindrical housing 9 axially positioned on the hub 1 by plain bearings 10 which allow relative rotation, rotation of the housing 9 being prevented by anchoring means such as springs. The strain gauges 12 are connected into a four active arm bridge, the output from which is indicated and/or recorded. A second embodiment (Figs. 3, 4, not shown) discloses a coupling as above but the axial length of which is readily adjustable by either having a series of hub portions 1 of differing lengths, or by making both flanged portions 2, 5 detachable and located on the hub by necked portions of differing lengths. So that the driveshaft may be used in the absence of the torque measuring coupling, a dummy coupling having no spokes but integrally formed flanges and hub portions, may be substituted.

Abstract: 450,899. Endless - belt conveyers. NYBORG, T. G., and MINING ENGINEERING CO., Ltd., Meco Works, Worcester. June 1, 1935, No. 16005. [Class 78 (i)] A driving head or unit for an endlessbelt conveyer, more particularly for use in coal-mines where height is limited, comprises three or more pairs of relatively small mangle rollers 6-11 arranged close together and operating on the return run of the belt from a delivery drum 3.

Filed: 1944-08-22
Abstract: A catalyst for the oxidation of ethylene to ethylene oxide comprises metallic silver, an oxide of tin or cadmium, and calcium oxalate or carbonate or amixture thereof.  The catalyst may be prepared by adding sodium oxalate to an aqueous solution of silver nitrate and calcium nitrate, decomposing the precipitate in the presence of liquid water at 140-300 DEG C., preferably in the presence of an inert gas such as carbon dioxide or nitrogen, and incorporating an oxide of tin or cadmium in the powder so formed. In an example the precipitate is mixed with water and heated in an autoclave to 230 DEG C. under a pressure of 175 kgms. per sq. cm.  The catalyst may be mixed to a paste with ethylene glycol and applied as a thin film to a carrier or support, for example as described in Specification 591,669.ALSO:In the preparation of a silver catalyst (see Group III) sodium oxalate is added to an aqueous solution of silver nitrate and calcium nitrate and the precipitate decomposed in the presence of liquid water at 140-300 DEG  C., preferably in the presence of an inert gas, such as carbon dioxide or nitrogen, to form metallic silver.

[Class 103 (i)] Modified hand releasing means such as described in the parent Specification, for vehicle brakes that are applied by a spring or other energy storing device and held off by fluid-pressure or vacuum comprise a nut 34 on a screwed spindle 32 mounted in a fixed frame 27 for rotation by a crank handle 33. The nut is adapted to be coupled to a cable 20 connected to the piston rod of the cylinder by which the brakes are normally released, by a pawl lever 26 pivoted at 25 to a rod 23 slidable in the frame 27. When it is desired to release the brakes by hand, the pawl is engaged with the nut by pressing on an arm 29 of the pawl and the nut is traversed by turning the crank 33, the tension in the cable holding the pawl engaged with the nut. When, however, the fluid-pressure or vacuum is established in the cylinder, the piston moves farther inwards thus slackening the cable and permitting a spring 30 to disengage the pawl so that the brakes may then be applied by the fluid-pressure control. Specification 334,880, [Class 103 (i)], also is referred to.

Abstract: 312,364. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). May 25, 1928, [Convention date]. Dynamos, regulating; motors, controlling. -A 3-phase winding to give two pole numbers in the ratio 1 : 3 and having a mean coil width equal to the lesser pole-pitch consists of a number of coils permanently connected into a closed winding and so arranged that when tapped for the lower and higher pole numbers respectively, the coils belonging to the same phase are connected in parallel and in series, the three sets of windings comprising the three phases being in both cases connected in delta. Figs. 1 and 2 show a winding having nine coil groups 1<a>, 1<e>, 2<a>, 2<e>, 9<a>, 9<e> which form a closed winding by means of end connectors having the different pitches shown. When tapped, as in Fig. 1, at the junction points 1<a>-2<a>, 8<e>-9<e> and 3<a>-7<e> a 6-pole 3- phase winding is obtained consisting of three groups, each comprising six coils and connected together in delta between the tapping points I, II, III. When three taps per phase (I), (II), (III), Fig. 2, are employed at the points shown, a 2-pole 3-phase winding is obtained, each phase comprising three groups, each consisting of three coils connected in parallel. These phase groups, as before, are connected in delta. Thus, the phase group between lines (I) and (II) consists of the three coils 1<a>, 1<e>, 2a, 2e and 3<a>, 3<e> joined in parallel. This group is delta-connected with the two similar groups which exist between the lines (II)-(III) and (III)-(I). The magnetic stresses in the teeth and gaps remain the samewith both methods of tapping the windings.

Title: Manufacture of organic sulphur-containing polymers and novel cold-setting products obtained therefrom
IPC: C08L81/00
Filed: 1946-05-29
Abstract: A process for the production of a liquid product suitable for the preparation of cold-setting compositions comprises esterifying a liquid disulphide acetal thioplast having terminal hydroxyl groups by heating an anhydrous mixture thereof with a dicarboxylic acid or an acid chloride or anhydride of such an acid and cooling the mixture after thickening occurs but before gelation sets in. The preparation of a suitable thioplast is described in Specification 618,440.  The acid is preferably of the type HOOC-R-COOH, where R is an aliphatic hydrocarbon radical, a hydroxy derivative thereof, or an arylene radical or an anhydride of such an acid.  Particularly suitable are acids where R is an aliphatic hydrocarbon radical or hydroxy derivative thereof containing 2-6 carbon atoms, e.g. succinic, tartaric, maleic and adipic acids, and where R is an arylene radical, such acids as phthalic and terephthalic.  Suitable anhydrides are succinic, maleic, adipic and phthalic.  In the esterification catalysts such as sulphuric acid, orthophosphoric acid, benzenesulphonic acid or toluene sulphonic acid may be used, and afterwards removed by washing with water or by neutralization.  A cold setting composition is obtained by mixing the product with a divalent metal oxide, in amount one to two parts for every part of the liquid.  Suitable oxides are zinc oxide, litharge, quicklime and magnesium oxide.  In examples, in which the acid degraded thioplast prepared as in the example of Specification 618,440, is employed (1) the acid-degraded thioplast is heated with stirring with tartaric acid, cooled, and decanted from unreacted tartaric acid.  One part of syrup mixed with 1.5 parts of zinc oxide is applied to a riveted joint in aluminium sheets, undergoing preliminary hardening in 40 minutes and forming a flexible coating in 3 days; (2) a mixture of acid-degraded thioplast after heating with phthalic anhydride is cooled and after mixing with zinc oxide and being applied to an aluminium sheet sets to a flexible coating in two days.
