Title: Improvement in and relating to apparatus for the long distance control of a body able to be stabilised by a gyroscope
IPC: F41G5/16
Filed: 1920-07-05
Abstract: 146,478. Krupp Akt.-Ges., F. June 21, 1917, [Convention date]. Gyroscopic apparatus.-Relates to the distant control of gyrostatic apparatus, such as is employed in gun-laying. Deflexion of the gyrostatic apparatus at the control station varies resistance in an electric circuit, whereby magnets at the receiving station impress a corresponding deflexion upon the gyrostatic apparatus situated there. In the construction shown, the gyrostatic apparatus at the control station comprises a gyroscope A mounted on a cardan suspension inside a casing B. The axis, which is at right-angles to the axis of rotation of the gyroscope, carries a sighting telescope C<1> and can be rocked by a hand-wheel and worm-gearing D or by applying force to a projecting rib e<1> on the suspension ring E. Any such movement deflects an electric contact arm c<2> from the middle position on a resistance wire b' and thus sends current into the neutral wire K<6> of a wheatstone-bridge arrangement. The current is used to deflect two galvanometers, one of which k<4> serves as a visible index to a gun-layer, and the other k<7> completes one of two auxiliary circuits leading to two electro-magnets g<4>, g<5> mounted on a gyrostatic apparatus G at the receiving station. Depending on which of these magnets is excited, the axis H, parallel to the axis C, is rocked in the same direction and through the same angle, the movement ceasing when a contact-arm h' travelling over a resistance wire g<1> restores the balance in the wheatstone bridge K<6>.

Title: Improvements in or relating to photographic materials
IPC: G03C1/76
Filed: 1961-05-23
Abstract: 991,893. Photographic emulsions. HONEYWELL Inc. May 23, 1961 [May 25, 1960], No. 18604/61. Heading G2C. A light sensitive silver halide print-out emulsion is overcoated with a polymeric aqueous emulsion containing either cupric chloride or cupric bromide and a water-soluble formate. In the examples the polymeric aqueous emulsion is polyvinylacetate and the formate is sodium, potassium or ammonium formate. The cupric salt solution and the formate solution are mixed and added to the polymeric emulsion and this mixture applied to the silver halide emulsion by transfer, roller coating, dipcoating or spreading with a doctor knife. The silver halide emulsion may be prepared by precipitating silver bromo-iodide alone by adding hot ammoniacal s ilver nitrate to a hot solution of potassium bromide and potassium iodide dissolving this silver salt and cadmium iodide in water and dispersing this solution in hydroxyethyl starch and coating the emulsion on paper. Specification 924,658 is referred to.
Patent GB-182809-A (GB)
Title: Improved cartridge-feed mechanism for automatic fire-arms
IPC: F41A17/40
Filed: 1922-02-20
Abstract: 182,809. Sutter; C. March 25, 1921, [Convention date]. Machine guns.-Cartridge feed mechanism of the kind comprising a feed-lever P, Figs. 4 and 4<a>, which is rocked about a vertical pivot p<9> to advance the cartridge strip by the engagement of its projection p<1> in a groove k' in the breechblock K is characterized by a feed-lever displaceable downwards about a horizontal pivot p<3> to cause the projection p<1> to hold the breech-block open when an exhausted cartridge strip is ejected from the gun. The cartridges are carried beneath feed strips X, Fig. I., which are fed through the feed-box F by the claw p<2> on the feed-lever which engages with the central openings x of the strip. The lever P is detachably mounted beneath the hinged top cover G by means of a plate p<6> which is retained by clips g<5>, g<6>. The plate p<6> carries the horizontal pivot p<3> and can also rock about the vertical pivot p<9>, which is retained by the spring h' of the detachable backsight H. When a feed strip is exhausted and ejected from the gun, the claw p<2> of the feed-lever is no longer in engagement with the strip and the lever is therefore depressed about its pivot p<3> by a spring p<5> to cause its projection p<1> to hold the breechblock open. The retaining pawl g<2> of the feed strip is mounted on the hinge g<1> of the cover G. The feed-block F, Fig. 11, carries the ejector f<1>, a tongue f<5> for removing cartridges from the strip and hinged flaps f<10>, f<11>. The top cover is retained by a catch g<3>, the spring-controlled pin g<9> of which carries a roller g<10> against which an incline p<4> at the rear end of the feed-lever bears under the pressure of the spring p<5> when the cover is open. On swinging down the cover, the lug p<1> is therefore always in the correct position to engage the groove k<3> in the breech-block whether the block is in the open or closed position. The slide h<6> of the leaf backsight is cylindrical in form, and the sight is detachably fixed to the cover G by a projection h<1> and by the feed-lever pin p'. The parts of the gun can be readily disassembled. The barrel A is screwed to the receiver E which slidably supports a stockcarrier I fastened by a pin i' which is retained by the catch g<3> of the top cover. The receiver is slotted to permit passage of the stud l<2> of the cocking-handle L which is normally retained in forward position by a spring, the stud l<2> engaging a recess in the motor piston J when the cocking- handle is moved to the rear.
Patent GB-748613-A (GB)
Title: Method of plating wire and apparatus therefor
IPC: C23C16/54
Filed: 1953-07-06
Abstract: 748,613. Coating with metals. COMMONWEALTH ENGINEERING CO. OF OHIO. July 6, 1953, No. 18716/53. Class 82(2). Continuous lengths of metal wire are coated with metal by thermal decomposition of a metalbearing gas, the wire being moved continuously in the direction of its length through a plurality of chambers, one of which is a gas-tight plating chamber in which the wire is heated to the decomposition temperature of the gas and in which the gas is circulated in contact with the wire. Examples of metal-bearing gases include nickel, iron, chromium, molybdenum and cobalt carbonyls, copper nitroxyl, cobalt nitrosyl carbonyl, antimony and tin hydrides, osmium carbonyl bromide and ruthenium carbonyl chloride ; these may be admixed with inert gases such as carbon dioxide, helium, nitrogen, hydrogen and the product of controlled burning of oxygen-free hydrocrabons. Heating may be effected electrically, using the wire as a resistance heater and shunts being used in parallel with the plating zones. Wire passes from a spool 19, Fig. 1, through a seal 20, chamber 11 and seal 21 to a spool 20, the chamber 11 being divided by elements 18 into annealing chambers 12, 14, 16 and plating chambers 13, 15. The arch 20, Fig. 2, comprises a cup 25 containing mercury or a low melting point alloy and a support 26 carrying pulleys 27, 28, 29. Each element 18 comprises a block 40 having tapered bores 41, 42, an extension 45 supporting a mercury contact 46 and ports 47, 49 to receive tubes 48a, 49a: the wire passes through an aperture 44 in the bore 42. When an element 18 is an end member, the bore 42 is connected by a tube 48 to the seal 80, the opposite end of the element being connected to the chamber 12 and the port 47 being closed. Otherwise, the element 18 is connected to adjoining chambers. Plating gas flows in countercurrent to the movement of the wire through chambers 13, 15 and inert gas through chambers 12, 14, 16, the tubes 48a, 49a serving as inlets and outlets. Each compartment may be fed with gas separately or the compartments 13, 15 may be fed in series, as may the compartments 12, 14, 16.

Title: Improvements relating to the separation of materials by flotation
IPC: B03D1/04
Filed: 1937-07-06
Abstract: 494,190. Separating materials by flotation. ELMORE, A. S., and COAL CONCENTRATION CO., Ltd. July 6, 1937, No. 18763. [Class 82 (ii)] In a vacuum process of separating materials by flotation, i.e. a process in which a pulp of the material is sucked up through a pipe into a separating chamber by maintaining a reduced pressure therein, the pulp is caused to ascend as a substantially vertical stream free from change of direction and travelling at approximately constant velocity and means are provided whereby it distributes itself rapidly in the body of liquid wherein the separation occurs. The rapid distribution may be effected by making the discharge area of the suction pipe an annulus instead of a disc. In the form shown the pulp is sucked up the pipe e into the separating vessel which comprises two conical portions a and b, a discharge d for the gangue, and a throat c provided with a receiver for the values. The suction pipe is provided with an annular discharge h by inserting a cone f which is preferably hollow and is provided with distance pieces g. The cone is preferably a double cone, as shown, the upright portion being shbrter than the inverted portion. To maintain an approximately constant velocity in the rising pulp the suction pipe is tapered as described in Specification 275,778, [Class 82 (ii)], the tapered portion being preferably removable so that pipes of different taper can be used in the same vessel. The liquid in the separating vessel is preferably subjected to pulsations, e.g. by the means described in Specification 191,383, [Class 82 (ii)]

Title: Improvements in and relating to rotary liquid switching devices
IPC: H01H29/00
Filed: 1935-07-01
Abstract: 447,095. Commutator switching- arrangements. SIEMENS -SCHUCKERT - WERKE AKT.-GES., Siemensstadt, Berlin. July 1, 1935, Nos. 18807 and 18808. Convention dates, June 30, 1934 and Nov. 2, 1934. [Class 38 (ii)] [See also Group XXXVII] In rotary con ducting - liquid switches, particu larly rectifiers, o the kind in which a conductive liquid such as an electro lyte, is rotated in a container 1 so as to form by centrifugal action a contact layer of the liquid against the outer wall of the container, in which layer metallic contacts dip to establish the desired connections, the contacts, which are arranged to rotate in the container, are divided into two or more adjacently located groups according to phases or output. In the arrangement shown, for rectifying six-phase currents, the secondary windings of a phase transformer are connected by slip rings 6, 7 to two groups 4, 5 of three contacts, which are rotated in the layer of conducting liquid in synchronism with the alternating current. The star point of the transformer is connected through the D.C. circuit and the container to the layer of conducting liquid. With this arrangement, the overall length of the slip rings is reduced to one-half, as compared with the known arrangement employing a single group of rotating contacts. In a modification, two groups of rotating contacts with six contacts in each group is provided ; in this arrangement the contacts and slip rings are connected in parallel so that each carries only half the output, its height being correspondingly reduced. In another arrangement the contacts for the six phases are each divided into two three-phase groups, and each group is subdivided into two groups, each carrying half the output. The slip ring for taking off the direct current may be arranged centrally between the groups of slip rings for the supply of alternating current. The bearings for the shafts carrying the A.C. slip rings may be adjustable laterally, to permit of variation in the depth of immersion of the rotating contacts in the layer of conducting liquid.

Title: Automatic well drilling apparatus
IPC: E21B19/08
Filed: 1962-05-16
Abstract: 954,328. Winches; tension regulating. M. E. CALDWELL, M. E. CAMPBELL, and A. G. SCHUESSLER. May 16, 1962 [May 24, 1961], No. 18814/62. Heading B8B. [Also in Divisions E1 and G3] Apparatus for maintaining a predetermined pressure on the tool of a rotary drill 30 comprises a drill support 20, means 38 for measuring the tension in the support, means 24 for holding the support, means 76 for releasing the means 24 when a predetermined tension is exceeded, and means 94 for intermittently locking the means 24 for short times in response to descent of the tool and irrespective of the tension. The deadline 30 of the support cable 20 passes about the capsule 38 which is connected to a Bourdon tube 40 the end 44 of which moves in response to changes in the tension in the deadline. The end is connected to a flapper 46 pivotable about an adjustable fulcrum 54 to open or restrict a nozzle 48. Some of the air fed to a pipe 58 passes through the nozzle and the rest passes through pipes 64, 70. The normal flow through the pipe 64 causes the release means 76 to hold a brake lever 32 so that the reel 24 holding the fast line 27 of the support cable is fixed, but on the point of release. An increase in the deadline tension restricts the nozzle and causes an increase in pressure on a valve 66 which opens wider to permit greater flow through the pipe 64 to the lower part of the cylinder 78 of the release to raise the piston 82 and lever 32 to release the brake. The air from the pipe 70 flows into a cylinder 72 to pivot the rotary relief valve 94 to engage its friction wheel 98 with the reel so that the valve is driven as the fast line is paid out. Discs 112, 114 are fixed to rotate with the shaft 96 of the wheel and are biased by a spring 116 against the end-plates of the body 104 of the rotary valve. The discs are each provided with equidistantly spaced ports, the ports in one disc being staggered from the ports of the other disc so that the valve inlet 107 is open or closed when the valve outlet 109 is closed or open. Some of the air from the pipe 64 passes through a pipe 92 to the inlet of the rotary valve, air being intermittently exhausted through the valve to reduce the pressure in the cylinder 76 to cause the lever 32 to intermittently lock the reel during paying out of the fast line. The tension measuring means may be an electronic system which actuates a fluid-operated brake release to pay out predetermined lengths of line.

Title: A process for burning oil
IPC: F23C99/00
Filed: 1935-07-04
Abstract: To prevent corrosion of the refractory brickwork of furnaces burning heavy oil containing inorganic constituents which have a fluxing action on the brickwork, an admixture in a finely divided state, particularly one containing silicic acid, is provided in the flame capable of forming at the prevailing temperature compounds which do not react further with the brickwork and which form a protective layer, the quantity of the admixture being sufficient to combine with the total quantity of the inorganic constituents of the oil.  The admixture may be suspended in the oil or may be fed in powder form or as an aqueous suspension into the flame.  Examples: To a fuel oil containing 0,2 per cent of ash, 0,2 per cent of acid clay may be added.  In the case of soda asphalt containing 6 per cent of ash, 3 per cent of an admixture rich in silicic acid is sufficient to form the desired protective layer on the brickwork.

Abstract: 1,110,062. Controlling convertible aircraft. LOCKHEED AIRCRAFT CORPORATION. 6 May, 1965 [13 May, 1964], No. 19250/65. Headings B7G and B7W. [Also in Division E2] A convertible aircraft comprises fixed wings and a rigid helicopter rotor which can be stopped in flight and has a horizontal vane 34 attached to the swashplate 48 to reduce the gust response of the relatively slowly rotating rotor during the transition from the helicopter to the aeroplane mode of flight by tilting the swashplate to vary the blade pitch. The effectiveness of the vane is made to vary with speed by attaching to the opposite side of the swashplate a spring 58 put under tension by hydraulic pressure from a pump (68, Fig. 3, not shown), driven by the rotor shaft. The vane is therefore relatively ineffective during the helicopter mode of flight, the controls for which are as described in Specification 1,027,011.  The rotor has two blades and is slowed down by a brake (40) and held with the blades extending fore-and-aft by a detent on a pneumatically-operated pivot arm enjoying a groove in a lock plate keyed to the rotor shaft (Fig. 7, not shown, and sec Division E2).
