Title: Improvements in and relating to electrically controlled mechanical milking installations
IPC: A01J5/04
Filed: 1945-11-21
Abstract: 638,487. Milking-machines. ALFA-LAVAL CO., Ltd., and CLARK, T. L. Nov. 21, 1945, No.31342. [Class 84] In an electrically-controlled cow-milking machine installation, electrically-insulated cables 3 extending along the suction pipe line 4 are secured in a flanged trough-shaped conduit 5 by spring clips 6 spaced along the pipe. At the angle-taps 7, the cables 3 pass through holes in contact blocks 10, 11, connection being made by pointed grub-screws 12 piercing the cables. One cable-connection 9 is of spring metal supported between insulated washers on projections 7a from the tap 7, the end 9a being bent as illustrated so that the tip does not scrape against the ferrule 8a when the hose 8 leading to the milk pail is put on or withdrawn. The other cableconnection is through the body of the angle tap to a sleeve within the end of the hose 8. Specification 638,486, [Group XXVIII], is referred to.

Title: Railway system
IPC: F16C39/06
Filed: 1972-07-05
Abstract: 1346746 Railway systems KRAUSS-MAFFEI AG 5 July 1972 [28 July 1971] 31454/72 Heading B7L A vehicle body is levitated with respect to a rail 3 by a series of permanent magnets 14 disposed thereon, the magnets 14 providing a considerable part of the supporting force necessary, and interspersed therebetween a series of electromagnets 13 each fed through a regulating circuit 4 controlled by a sensor (not shown) which detects the gap between the vehicle and the rail and regulates the energizing current to maintain a substantially constant gap. The magnets 14 may be ferromagnetic permanent magnets but preferably are made from sintered magnetic material especially samarium. Alternatively electromagnets may be employed. The electromagnets 13 are disposed so as to influence the field pattern of the magnets 14 with like poles adjacent each other as shown. Increase of the current supplied to the electromagnets 13 will maximize the useful flux of the supporting magnets, whilst under some conditions the supply current to the magnets 13 may even be reversed to give the necessary clearance in flux to prevent contact between the vehicle and the rail 3. In an alternative embodiment the magnets 14 are removed from the influence of the electromagnets 13 by being disposed each within a flux conducting shield and in this case contact between the magnets 14 and the rail 3 is prevented by spacing them further from the rail than the polepieces of the electromagnets 13.

Title: An improved manufacture of resins and of coating compositions containing such resins
IPC: C09D123/28
Filed: 1939-12-04
Abstract: 539,416. Halogenated iso-olefine polymers, nitrocellulose compositions. STANDARD OIL DEVELOPMENT CO. Dec. 4, 1939, No. 31461. Convention date, Dec. 31, 1938. Addition to 511,418. Drawings to Specification. [Classes 2 (ii) and 2 (iii)] Hard resinous halogen derivatives are prepared from iso-olefine polymers of molecular weight between 1,000 and 500,000 by treating the polymers with a halogen for a sufficient time to effect the chemical incorporation in the halogenated product of between 55 per cent. and 75 per cent. by weight of halogen. The halogenation may be carried out in the dark or in the light, but preferably in the presence of sunlight or a stronger source of ultra violet light, fairly stringent conditions, e.g. heat and/or light and/or polymerization catalysts, being used in the final stages ; chlorene may be used in the liquid form, or gaseous chlorine may be bubbled through a solution of the polymer in a solvent such as carbon tetrachloride, chloroform, or ethylene dichloride; iodine, antimony halide, or ferric chloride may be used as a catalyst.' The halogenated derivatives may be separated from the solution as described in the parent Specification. Corrosive constituents such as chlorine or decomposition products may be removed from the halogenated derivatives by washing with an alkaline solution or by incorporating a basic material such as a quaternary ammonium base, e.g. tetramethyl ammonium hydroxide. In an example, gaseous chlorine is passed into a solution of polyisobutylene in carbon tetrachloride in direct sunlight at room temperature at a rate to maintain an excess of chlorine. The product is precipitated by addition of alcohol, washed with water, and pressed between the plates of a heated press. Solutions of the products dry rapidly, and are useful in the preparation of coating compositions, e.g. paints, lacquers or varnishes ; they also have a lower viscosity than solutions of products of lower chlorine content. The products have a lower refractive index than products of lower chlorine content and are thus useful in the manufacture of lenses and laminated glass. Lists are given in the Specification of solvents, plasticizers, waxes and waxy compounds, gums, drying oils, and other compounds with which the halogenated derivatives may be compounded in the preparation of paints and like coating compositions. In examples of such compositions a chlorinated isobutylene polymer is compounded with (1) boiled tung oil, hydrogenated methyl abietate, iron oxide and a thinner, e.g. a mixture of sulphur dioxide extracts of a petroleum distillate and petroleum naphtha, (2) nitrocellulose containing 20 to 25 per cent. of alcohol, blue pigment, a sulphur dioxide extract of a petroleum distillate and a mixture of toluol, ethyl acetate, butanol and butyl acetate, and (3) hydrogenated methyl abietate, a sulphur dioxide extract of a petroleum distillate, and ethyl acetate.

Abstract: 680,748. Electric indicating systems. LIQUIDOMETER CORPORATION. Dec. 28, 1950 [March 14, 1950], No. 31479/50. Class 40 (i) [Also in Group XXXVI] In a device for measuring or controlling a variable such as liquid level, temperature, humidity &c. wherein a variable reactance responsive to the variable controls the frequency of an oscillator, the variable reactance forms part of a parallel tuned circuit included in a negative feed-back path of the oscillator. As shown, for measuring the quantity of liquid in one or a plurality of tanks 6A, 6B, 6C, immersion type condensers 2A, 2B, 2C in the respective tanks are parallel connected across an inductance 72 to form a parallel tuned circuit. The oscillator 15 consists of thermionic valves 22, 24 the variable frequency output being taken from the grid 32 of the cathode follower 24 and actuating a resultant field type meter 116 through an amplifier 76, and discriminator 78 as described in Specification 670,149. Positive feedback from valve 24 is effected over lead 54 and resistor 56 to the cathode of valve 22 and negative feedback is effected over lead 54 resistor 66, condenser 68 and the parallel tuned measuring circuit 72, 2A-2C to the grid of valve 22. The positive feedback effect is swamped by the negative feedback except at the resonant frequency when the high impedance presented by the tuned circuit to the negative feedback path greatly attenuates the negative feedback and permits oscillation at the resonance frequency, this frequency being substantially independent of stray capacities between the cables 16, 18 and earth. The measuring condensers may be replaced by one or a plurality of series connected inductances. By using a sequence switch the magnitude of a plurality of conditions may be measured in turn. Temperature may be measured by using temperature sensitive condensers and moisture content by passing the moisture containing material through a measuring condenser.

Polymerization may be effected in the substantial absence of solvents-some benzene or cyclohexane may be used in introducing catalyst-and is optionally in the presence of propane as modifier.  The products form films of improved transparency. Specification 612,266 and U.S.A. Specification 2,497,323 are referred to.
