Title: Improvements in epicyclic variable speed and transmission gearing
IPC: F16H61/02
Filed: 1932-11-02
Abstract: 408,361. Change speed gearing ; differential gearing. JEFFARES, W., 11, Browning Drive, Londonderry, Northern Ireland. Nov. 2, 1932, No. 30836. [Class 80 (ii).] The invention comprises an epicyclic train combined with a screw device which locks for solid driving and allows overrunning. In a two-speed gear T, Fig. 1, of which O and U are the driving and driven shafts, a loose sun gear C is adapted to be held fast by means acting at C' to yield a reduced drive. This is because stepped planets E<1>, F<1> carried by a spider A<4> upon the shaft O mesh with the gear C and also with a larger gear D fast on the load shaft U. A boss or sleeve rigid with the gear C is screw-threaded at C<1> and upon this is a nut C' with a ratchet toothed periphery C<4>. When the holding-means at C<6> is removed, and a pawl advanced to engage at C<4> so as to prevent the nut C' from turning backwards, the nut C<2> screws along the sleeve C<1> and engages the spider A<4> at C<3> so that the gearing turns solid on a high speed which overruns owing to reversal of the screwing. The shaft 0 is the driven shaft of a change-speed and reversing unit Y which is driven through an automatic clutch, not described, driving on to a sleeve A<2>. When the unit Y is in reverse, the two-speed gear T will not transmit any drive except on low speed. A five-speed and reversing gear, embodying the invention, has triple planet pinions and yields a drive above solid drive. Differential or balance gearing embodying the invention is shown in Fig. 3. A propeller shaft pinion W drives a pair of connected discs X, each of which carries the annulus B of the epicyclic train. The planets of these trains are supported on spiders L fast on the twopart axles U. The sun gears R are loose and have screwed sleeves R<2> with nuts R<6> with ratchet toothed peripheries R<4>. In forward driving, pawls engage at R<4> to prevent reversed turning of the nuts R<6> so that the parts screw up and jam, yielding solid driving which allows either or both part axles U to overrun. In order to transmit a reversed drive, a low-speed is engaged which is effected by holding either or both sun gears R stationary by discs &c., not shown, like the disc C<6> of Fig. 1.

Title: Improvements in or relating to x-ray spectrometers
IPC: H01J37/252
Filed: 1958-09-26
Abstract: 900,645. X-Ray spectrometers; viewfrinders LABORATOIRE SUISSE DE RECHERCHES HORLOGERES. Sept. 26, 1958 [Sept. 26, 1957], No. 30843/58. Classes 97 (1) and 98 (1). In an X-ray spectrometer including means for producing a fine electron beam capable of being directed on to an object so as to produce X-rays which are reflected by an analyzer crystal, mechanical means are provided for increasing the resolving power of the spectrometer by changing the response to incident X-rays of only those surface portions of the analyzer crystal which impair the resolving power. Either the crystal 11 is mounted in a holder 12 provided with tapped holes in which correcting screws are inserted for locally varying the radius of curvature of the crystal or those portions of the crystal which impair the resolving power are covered with a material which absorbs the X-rays produced by the object and does not produce any appreciable secondary radiation or scattering. The fine electron beam may be produced by an electron microscope as described in Specification 899,291 and the object may be examined simultaneously by electron microscopy and X-ray spectrometry. To facilitate control of the position of the incident electron beam of the electron microscope 1 ... 6 on the object 8, a beam of light from a lamp 23 is reflected by mirror 25 on to the object and an image formed by the reflective objective 20, 21 is reflected by the semi-transparent mirror 19 into an eyepiece 18.
Patent GB-222718-A (GB)
Title: Improvements in and relating to the manufacture of alkali metal amides
IPC: C01B21/092
Filed: 1923-12-08
Abstract: 222,718. Ewan, T. Dec. 8, 1923. Alkali amides are obtained by the reaction of liquid anhydrous ammonia containing a dissolved salt such as alkali cyanide upon an alkali metal in the presence of a catalyst. The sodium solution may be made by electrolyzing a solution of sodium cyanide in liquid anhydrous ammonia with sodium amalgam as anode as described in Specifications 218,373 and 218,563, [both in Class 41, Electrolysis], and the ebonite lining of the cell may be omitted, allowing the cell-wall, which is made of an active catalyst such as high-carbon steel to come in contact with the sodium solution; or sodium from any source may be dissolved in the liquid anhydrous ammonia. The drawing shows an electrolytic cell 1 similar to that described in Specification 218,373, the cathode being of high-carbon steel. Additional catalytic surfaces 3 are arranged near the surface of the electrolyte 4 in contact with both the sodium solution and the electrolyte. The electrolyte overflows by a pipe 5 into a filter 6 without affecting the level of the electrolyte in the cell 1. Fresh sodium cyanide is continually fed in from a reservoir 7 and the amide is collected in the filter 6, the filtrate being led back to the reservoir 7. The sodamide is washed with liquid ammonia admitted through a pipe 9. while a duplicate filter (not shown) is in use, the washed amide being melted and run into moulds through a pipe 10. Alternatively solid sodium is placed in a vessel 12, Fig. 2, through a door 13, and a solution of sodium cyanide in liquid ammonia is placed in a vessel 14. Preferably the proportions of the sodium, ammonia, and cyanide are such that two layers are formed. The cyanide solution is run into the vessel 12 by a pipe 15. The sodium solution floats upon the cyanide solution and both are in contact with the steel walls of the vessel and with catalytic surfaces 16. In another alternative a solution of sodium in liquid ammonia is run into a vessel such as 12 in which high-carbon steel is used as catalyst without a dissolved salt. The reaction is effected more slowly but the product need not be washed.

Abstract: 197,971. Hamon, Count L. le W., and Byrom, T. H. Nov. 18, 1921. Charcoal.-Peat, lignite, sawdust, or other carbonaceous material is saturated under pressure or otherwise with a metallic salt solution and a soluble phosphate, carbonate and/or silicate is added to precipitate in the pores of the material an insoluble phosphate &c. The material is then carbonized and soluble matter extracted. In an example 'aluminium sulphate and magnesium and calcium chlorides are given as suitable salts and phosphoric acid as the precipitant. Hydrochloric acid, with or without heat, is used to extract the soluble matter after carbonization, and the carbon is subsequently dried. The salts obtained in the extraction may be employed in the impregnation of fresh material.

Abstract: 654,845. Aircraft controls. FAIREY AVIATION CO., Ltd. Nov. 21, 1947, No. 30961. [Class 4] The means for actuating an aircraft control surface comprises a manual control arranged to operate a main linkage 12, 13, 14, 16, 17 terminating in a lever arm 18 secured to, and rotatable about the hinge axis of, the control surface 10, and a tab 11 operable by the manual control through a tab linkage 21, 19, 20 connected with the main linkage and including as an intermediate component a lever arm 19 coaxial with, but shorter than, the lever arm 18, the control surface and tab being at all times in direct and non-yielding connection with the manual control. In a modification (Fig. 2, not shown) an irreversible unit, e.g. that shown in Specification 636,506, [Group XXIV], replaces the member 14, the members 13 and 16 becoming respectively the driving and driven members of the unit. This arrangement provides " feel " to the control surface and renders it self-centring, thus eliminating the usual disadvantages associated with the use of an irreversible unit.

Abstract: 152,890. Petrie, E. B. Dec. 11, 1919. Sunken ships, raising. - Comprises a pontoon divided into compartments, with means for regulating and indicating the flow of air into the compartments; clutches on both sides of the pontoon engaging cables to which are attached cross - chains connected under the wreck to a similar pontoon; and tackle for placing the crosschains under a sunken ship. The pcntoon, Fig. 5, is divided transversely by a partition 24, and provided with baffles 25, 27, having flap valves 26 to prevent surging of the water. A series of clutches 30 is provided on each side of the pontoon, and through each clutch is passed a cable 37 having at its lower end a hook for connexion to the cross-chains placed under the wreck. Valves 38, operated by compressed air through the pipes 50, control the admission and ejection of water, while air is admitted through the supply pipes 53 which are provided at the surface with pressure gauges and meters. The main air supply and the air for working the valves of each pontoon is derived from a separate accumulator on the surface ship. Steps are formed on the upper parts of the pontoon for the convenience of the divers who carry out the under-water operations. Fig. 1 shows ment of cables 12, 17, connected to a draft-chain 11. After being lowered into the position shown, the chain 11 is caused to saw through the mud under the wreck by alternately hauling on and the wreck A, the salvage ship B, and the arrangeslackening the cables 12. When in the desired position, the cables 17 are drawn taut, and one of the lifting cross-chains 18, Fig. 1<a>, is attached to the draft-chain and drawn under the wreck with it by means of the cables 17. A second cross-chain is drawn under from the opposite side in the same place, and the draft-chain released and drawn farther along to place a second pair of cross-chains. When a sufficient number of chains have been positioned, the pontoons D are lowered on each side of the wreck, and the crosschains 18 attached as shown in Fig. 4 to the lines 37 and hauled taut by means of the cables 65, 66, connecting the cables 37 with winches on the salvage ship. The clutches 30, Fig. 5, prevent any slackening of the chains. Lifting. cables from additional salvage ships are then attached to the lugs 29, and the water is expelled from the pontoons by the admission of air, the operation being controlled by the valves 38 so that the wreck is raised on an even keel.

Inventor: JACOBS DAVID IAN HUTCHINSON
IPC: C08K5/103
Filed: 1954-10-28
Abstract: Crystalline vinylidene chloride polymers are plasticised and stabilized against light and heat by incorporating in the polymer, e.g. during the preparation of the polymer, an ester of a non-gelled substantially linear polyether derived from meta- and/or para-bis-(alpha-hydroxy-ethyl) benzene.  The polymer may be polyvinylidene chloride or a copolymer of vinylidene chloride with one or more of the following monomers vinyl chloride, methyl or ethyl acrylate, methyl methacrylate, dimethyl or ethyl acrylate, methyl methacrylate, dimethyl or diethyl maleate, or vinyl acetate.  The esterifying acid may have the formula R.COOH or NHXCOOH, where R is an alkyl, aryl, or aralkyl group, X is an aryl group in which the aryl nucleus is attached directly to the N atom.  Esterifying compounds mentioned are acetic, propionic, butyric, benzoic, phthalic, and phenyl acetic acid, and alpha-naphthyl and phenyl isocyanate.  The ester may also be dry mixed with the polymer or dissolved in a volatile organic solvent and mixed with the powdered polymer, or mixed with an aqueous dispersion of the polymer. Solvents mentioned are acetone, ethanol, dioxan and benzene.  The compositions may also contain lubricants, pigments, dyes, other plasticisers and additional stabilizers such as 2-hydroxy-5-chlorobenzophenone. In an example, vinylidene chloride is polymerized with vinyl chloride in aqueous dispersion in the presence of o-chlorbenzoyl peroxide, pentaerythritol monostearate and the polyester obtained by heating para-1-bis-(alpha-hydroxy-ethyl) benzene with anhydrous oxalic acid which has been esterified with acetic anhydride.  The composition may be extruded into fibres, filaments or films. Specification 801,429 is referred to.

Filed: 1973-07-02
Abstract: 1390140 Testing networks TERADYNE Inc 2 July 1973 [13 July 1972] 31388/73 Heading G1U The test circuits disclosed in Specification 1390139 are used to test a complex matrix of wiring in the back plane of a printed circuit panel rack Fig.5 (not shown). The printed circuits of the tested equipment are replaced by a number of boards each containing several integrated circuits IC1-IC13 containing the decoding and test units described in the above Specification. In the example shown one hundred points in the interconnection matrix are tested by each board. The board Fig.4 further contains additional decoding means including a two stage shift register 71, 73 and two additional decoding matrices 67, 68. The boards in the rack (Fig.5) are connected serially using male and female connectors 91, 93 and selection of particular terminal points for testing is achieved in three stages. The bi-stables 71, 73 in the shift register chain extending over all the boards select which matrix 67 or 68 on a particular board is enabled. Coded signals A4-A6 select the integrated circuit IC1-IC13 and further signals A1-A3 select the terminal point. Unlike the system of Specification 1390139, two gate signals are available which can be applied to that group which has been addressed (select gate) or to all the other groups (master gate). Overall control of the test procedure is effected by a digital computer 100 by way of the control circuitry shown in Fig.6. The shift register is clocked by pulses from a gated oscillator which supplies the number of pulses necessary to shift the digit in the register to the  required place, the clock pulses are counted 115 and compared to the correct address supplied from the computer via register 103. The connections are tested by monitoring the supply current in the ground line, V ss  and comparing it to limits derived from the computer 100.

Abstract: 683,099. Actuation of switches. LANDIS& GYR AKT.-GES. Dec. 28, 1950 [Dec. 31, 1949], No. 31455/50. Class 38 (v) [Also in Group XXXVIII] In regulating apparatus of the chopper bar type (see Group XXXVIII) controlling an electric'switch the means serving to control the said switch are arranged so as not to interfere with the swinging motion of the chopper bar in performing its periodic feeling action on the primary measuring mechanism. In the embodiment described a three-point switch 7 has press-buttons 26 which operate switches, for example, tubes of mercury, wherever the associated control levers 27, 28 or 29 are allowed to pivot under stress of springs 33. Each control lever has an associated rotating cam 30 which normally restrains the control lever but periodically releases it at the same time as an associated cam 23 releases a corresponding chopper bar 1, 2 or 3 to pivot about axis 4 under stress of a tension spring 25. Each chopper bar has a projection 22 which coacts with a projection 32 on the relative control lever to restrain the latter from operating its switch button 26 unless the pointer 9 is in the desired position to cause operation of the switch, in which case a respective key lever 18 presses the member 11, carried on the pointer 9, against a fixed bar 10 and prevents the chopper bar moving to lock the control lever. The cams 23 and 30 for the various switch buttons 26 may be relatively adjustable angularly so that the feeling operations for the individual switch points occur at different times. The number of switch points may be other than three by providing a corresponding number of sets of elements between the pointer 9 and switch 7.

Abstract: 354,120. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Dome, R. B. ; 13, 9th Street, Schenectady, New York, U.S.A.) Oct. 21, 1930, No. 31559. Convention date, Oct. 23, 1929. [Class 40 (v).] A valve generator has a magneto-strictive coupling between anode and grid circuits and, in addition, independent means for energizing the grid circuit from the anode circuit. As shown, the oscillations generated by valve 1 are controlled in frequency by a magnetostrictive body 2 of nickel or of an alloy of nickel and iron, copper, cobalt, &c., which is wound with two coils, of which one, 3, is included in the anode circuit comprising the primary of the coupler 5 and a battery 6 shunted by a condenser 7, while the other, 4, is included in the grid circuit comprising the secondary of coupler 5, battery 13 shunted by condenser 8 and blocking condenser 9. The circuit comprising coils 3, 4, 5 is tuned to the oscillation frequency of the body 2 by a variable condenser 10 connected between the coils 3, 4. Grid bias is supplied through a choke 12 from battery 11, and the battery 13 sends an additional magnetizing current through coil 4, the circuit being completed by choke 14 and resistance 15. The feed-back due to the coupler 5 is arranged to be several times as great as that due to the magnetostrictive body.
