Title: Improvements in or relating to centrifugal clutches
IPC: F16D43/18
Filed: 1935-03-27
Abstract: 436,776. Friction clutches. ROESCH, G. H., and TALBOT, Ltd., C., Barlby Road, Ladbroke Grove, London. March 27, 1935, No. 9624. [Class 80 (ii)] A centrifugal friction clutch comprises a pair of shoes 35 adapted centrifugally to engage a driven drum 28, each shoe being pivoted at 32 at its leading end on a sleeve 30 which is rotatable freely on a drum 13 secured to the driving shaft 10, the trailing end of the shoe being secured by studs 40 to the trailing ends of a pair of tangentiallyarranged leaf springs 39, the leading ends of which are secured to the drum 13 by studs 42. Initial adjustment is provided by studs 50 adjustably screwed into the drum 13 and forming abutments for the studs 40. Webs 53, 54 projecting from the sleeve 30 into slots in the shoes engage between pairs of friction plugs 57, one plug of each pair being under the influence of a spring 61. The shoes are resiliently connected by rods 67, each of which has one end connected by a pin 70 to the trailing end of one shoe, while the other end of the rod extends through the leading end of the other shoe into a recess therein, a spring 64 being interposed between the bottom of the recess and a plate 65 held on the rod by a nut 66. The driven drum 28 is secured to a sleeve 21 splined on the driven shaft 18. Rollers 23 co-operate with the interior of the drum 13 and cam surfaces on a part 9 of the sleeve 21 to form a one-way clutch in parallel with the centrifugal clutch and arranged to prevent the driven shaft from over-running the driving shaft. Bearing rollers 25 are interposed between cylindrical parts of the member 9 and the drum 13.

Title: Improvements in or relating to mass flow measuring devices

IPC: G01F1/698
Filed: 1964-07-19
Abstract: 1,109,118. Measuring gas-flow electrically. HAWKER SIDDELEY DYNAMICS Ltd. July 13, 1965 [July 19, 1964], No.9645/64. Heading G1N. Apparatus for measuring the mass flow of a gas comprises a thermistor 2a (Fig. 1) in one arm of a bridge 1, electrically heated by an element 4 exposed to the gas-flow, the heater being fed with the bridge unbalance current, whereby an increase in the gas-flow reduces the temperature of thermistor 2a and unbalances the bridge, thereby feeding more current to the heater 4 to restore the bridge balance condition, the change in heater current, indicated at 7, representing the change in gas mass flow. As shown, five thermistors 2, 2a, 3 are connected in the bridge circuit and located in the gas-stream so that the bridge is insensitive to changes in the temperature of the gas. Thermistors 2 and 3 are thermally shielded from thermistor 2a and the heater 4. Thermistor 3 is connected in one arm in series with 2a to determine the heater current at zero gas-flow. In a modification, thermistor 3 is omitted and an A. C . voltage is added in the unbalance circuit to determine the initial heater current Fig. 6 (not shown). Thermistors 2 may be combined with or replaced by fixed resistors to produce the desired relationship between heater current and gas mass flow. The thermistors may be located in the main flow conduit or in a by-pass. In one embodiment Fig. 10 (not shown) a further thermistor in the gas-flow is used to control the gains of the unbalance amplifier to make the response independent of changes in the gas temperature.

Patent GB-610172-A (GB)
Title: Improvements in or relating to the production of organic nitriles
Filed: 1946-03-29
Abstract: Acrylonitrile and/or succinonitrile are produced by passing a gaseous mixture of hydrogen cyanide and ethylene oxide over a dehydration catalyst at 150-650 DEG  C.  In place of hydrogen cyanide any substance which will produce hydrogen cyanide under the reaction conditions may be used, e.g. formamide.  The reaction may be carried out by passing liquid ethylene oxide and liquid hydrogen cyanide into a heating zone to vaporize the reactants simultaneously, before or after contact with the catalyst. Suitable catalysts are compounds of metals from the 3rd, 4th, 5th, 6th and 8th groups of the Periodic table, especially the oxides of aluminium, thorium, silicon, vanadium, molybdenum, titanium, tungsten and nickel, also a metal of the platinum group or salts such as alums, basic aluminium salts or metal phosphates may be used.  The preferred catalyst is highly purified silica gel which may be prepared by neutralizing sodium silicate or by the hydrolysis of silicon halides or esters of orthosilicic acid. When acrylonitrile is required as the main product, the gas mixture should contain an excess of ethylene oxide over the equimolecular proportion, but when a large proportion of succinonitrile is required, the mixture should contain at least two molecular proportions of hydrogen cyanide for each molecular proportion of ethylene oxide.  Inert diluent gases such as nitrogen, hydrogen or carbon monoxide may be added to the feed mixture.  In examples: (1) a gaseous mixture of hydrogen cyanide and ethylene oxide (molar ratio of 1 : 2 1/2 ) is passed over alumina gel which has been previously dried in air at 400 DEG  C. Nitrogen is added to the feed mixture to keep the catalyst temperature within the range 260-280 DEG  C.  The issuing vapours are condensed and the condensate separates into an aqueous layer and an organic layer.  The latter is separated, dried and distilled to yield mainly acrylonitrile; (2) hydrogen cyanide and ethylene oxide in the molecular proportion of 2 : 1 are passed over silica gel at 350-400 DEG  C.  The liquid product is homogeneous and on distillation yields acrylonitrile and succinonitrile.

Title: Improved method of introducing an alkali or alkaline earth metal into an exhausted receptacle
IPC: H01J9/395
Filed: 1937-04-06
Abstract: 482,022. Electrode materials. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 6, 1937, No. 9808. Convention date. April 9, 1936. [Class 39 (i)] In order to produce a layer of alkali or alkaline earth metal in a discharge tube, either as a cathode or a secondary-emission surface, or for gettering, a mixture is employed consisting of a compound of the desired metal, a reducing agent, a second reducing agent and a substance which reacts with the second reducing-agent but not, in its presence, with the first reducing agent. It is stated that by these means the rate and temperature of the reaction can be controlled. A mixture for producing caesium consists of one part of caesium bichromate, two of zirconium (reacting with the caesium), two of chromic oxide, and two of aluminium (reacting with the oxide). For producing barium the caesium bichromate may be replaced by barium peroxide.

Abstract: 1470933 Building ships NIPPON KOKAN KK 10 March 1975 [20 March 1974] 9837/75 Heading B7S A building dock which is open at both ends is partitioned into a middle building area by a pair of detachable dock gates and two end building areas on either side of the middle area so that a stem section can be built in the middle area, then moved to one of the end building areas where the remaining hull sections are joined to it whilst a second stern section for a second ship is again built in the middle area. Work in the middle building area on a stern section is thereby uninterrupted by the flooding of either end area of the dock for the undocking of a completed hull. One end area of the dock may be used to build an entire ship whilst the middle area and other end area are used in the above manner to build a series of larger ships or the stern sections may be moved from the middle building area to each of the areas alternatively. As a third alternative, two stern sections may be built in the middle area of the dock simultaneously and then moved to a respective end area.

Abstract: 893,615. Cables. ANACONDA WIRE & CABLE CO. March 21, 1960 [March 21, 1959], No. 9885/60. Class 36. To avoid air-gaps in a cable between its polyethylene or polypropylene insulation and a contiguous semi-conducting electrostatic shielding comprising 20-60% polyvinyl acetate or chlorinated paraffin, 25-50% methylated paraffin and 10-50% carbon particles, the insulation is heated to an amorphous condition whilst in contact with said shield. Suitable compositions for shields applied to the conductor inside the insulation, when wax may be included, and applied to the outside of the insulation are specified. The conductor may be coated by passing it when heated through soft solid semi-conductive composition and then extruding over it, at more than 250‹ F. and at 200-1200 p.s.i., a layer of insulation. An outer semi-conductive layer may be applied by dipping, spraying, brushing or pouring on a solution, of the composition in a volatile solvent, e.g. ethylene dichloride, in which the carbon is suspended.
