Title: Apparatus for charging and discharging workpiece transporters
IPC: B65G49/02
Filed: 1965-01-27
Abstract: 1,086,904. Rotary conveyers. SCHERING A.G. Jan. 27, 1965 [Feb. 14, 1964], No. 3653/65. Heading B8A. Racks 6 (Fig. 2, not shown) carrying articles to be dipped in plating baths 5 are supported by members 10, 10 carried by carriers 7 running on rails 9. A pivotable rail section 15 enables the carriers 7 to pass from one set of rails 9 to a second set disposed in parallel relation. When a carrier 7 has passed on to the section 15, the latter turns to a position at 90 degrees to that shown in Fig. 1. The associated rack 6 is then in a position to be transferred to spaced supports formed by the upper extremities of a U-shaped member 23<SP>1</SP> carried by a turntable 16. The latter then rotates clockwise to bring a further rack 23<SP>11</SP> into position to receive another rack from the next carrier 7 to arrive on the rail section 15 and so on. The members 23 are pivotably mounted so as to be adapted to be tangentially disposed relative to the turntable 16 when they are not in the immediate vicinity of the loading/unloading station. In modifications (Figs. 3 and 4, not shown) only two supports 23 are carried by the turntable and the latter therefore oscillates between two positions instead of rotating continuously.

Title: Improvements in or relating to magnetron tubes
IPC: H04B1/16
Filed: 1936-02-06
Abstract: 458,631. Magnetrons. PINTSCH AKT.- GES., J., 71, Andreasstrasse, Berlin. Feb. 6, 1936, Nos. 3675, 3676, 3677, and 3678. Convention dates, Feb. 28, 1935, April 10, 1935, June 4, 1935, and June 4, 1935. [Class 39 (i)] A magnetron for ultra-short wave use has a cathode of filamentary form and a split anode surrounding the cathode, the segments of which anode are extended longitudinally to form a resonator, and the discharge space is bounded at its ends by conductive screens. In one form, Fig. 1, the cathode 1 is surrounded by a four-part anode of which one opposite pair of segments 3 is terminated by a plate 9 carrying the aerial 14 whilst the other pair 2, 4 is terminated by a plate 10. The discharge space is bounded by screens 6, 7 of which the screen 7 is supported on the outer of two concentric leads 19, 21. The lead 21 is supported by an insulator 22 from the shortcircuiting plate 8. The cathode is supported by a hook 26, a wire 25 which carries the plate 6, and an insulator 24 on the plate 9. A resonator of length n#/2 or (2n - 1).#/4 may be excited by a series of cathodes at each potential loop. The envelope may be a metal vessel to which the outer resonator 24 is connected. In a modification, Fig. 8, an indirectly-heated cathode 51 is surrounded by a two-part anode 52 and a series of metal screens 53, connected to a common lead are provided. With a directly-heated cathode, the common lead may be resistive so that decreasing biasses may be applied to successive screens. The cathode supports may be extended to shield the ends of the cathode, Fig. 10 (not shown). The screens may be combined to form a single helical surface. A straight wire in the middle of a hair-pin or four-wire cathode may be used for control purposes. The screens may in all cases be insulated or connected to the cathode or one or more may be positively biassed and used for modulating.

Title: Improvements in and relating to valve operating mechanism
IPC: F16K31/04
Filed: 1932-02-08
Abstract: 380,350. Control of motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Electricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Feb. 8, 1932, No. 3726. Convention date, Feb. 7, 1931. [Class 38 (iii).] Travelling to predetermined limits.-In a switching device for motor operated valves whereby the motor may be switched off when a predetermined valve position, or a certain resistance to further movement is attained, an essential rotatable member, such as a worm, worm wheel, nut, or screwed spindle is arranged to be axially displaced when the driving torque exceeds the limit so as to cause a friction flange, as 31, on the rotary part to engage a coaxial friction member, as 32, which operates the switch, as 35, by means of a radial arm or gearing. In the arrangement shown, when the axial movement of the screwed spindle 21 is unduly constrained or arrested, as by the closure of the valve, the nut 24 moves up, against the action of the spring 28, and carries the rotating friction plate 31 into contact with the friction plate 32 engaged by toothed gear 34 with the switch 35. A modification is shown in which the rotary screwed spindle itself moves axially to engage the friction surfaces operating the switch.
Patent GB-211488-A (GB)
Title: Improvements in and relating to the manufacture of sodium sulphide
IPC: C01B17/26
Filed: 1924-02-14
Abstract: The reduction of sodium sulphate, for instance by means of coal, is effected by complete fusion, for instance, in an electric furnace, in the presence of a small proportion of another sulphide, such as potassium sulphide, an alkaline earth sulphide or a heavy metal sulphide, which may be added as such or may be produced by reduction of the corresponding sulphate in situ.  The effect of the presence of the added sulphide is to render the mass fusible at a comparatively low temperature and the addition may be made when the mass begins to thicken as sodium sulphide accumulates, or at any other stage.  When an alkali or alkaline earth sulphide is employed it may be left in the product which may be cast into moulds or run into containers for sale or may be flaked by running over cooled rollers as is done with caustic soda and cyanide.  When a heavy metal sulphide is employed, such as copper, lead, zinc or iron sulphide, which may be an ore or the refined sulphide produced in the process, the product is leached with hot water which dissolves the sodium sulphide, leaving the heavy metal sulphide in a suspension which readily settles.  The sodium sulphide may then be crystallized.

Title: Sound reproducing diaphragm and a method of making the same
IPC: H04R31/00
Filed: 1935-02-06
Abstract: 451,657. Diaphragms. HAWLEY, J. B., 20, East Batavia Road, Geneva, Illinois, U.S.A. Feb. 6, 1935, No. 3875. Convention date, Feb. 12, 1934. [Class 40 (iv)] [See also Group V] A conical diaphragm is formed integral with a slightly - tapered voice-coil support by accreting fibrous material from a bath upon a former, and the voice-coil support is subsequently shaped to a cylindrical form to receive the coil. As shown, the diaphragm 25 with coil support 26, corrugated periphery 28, and margin 29 is formed upon a reticulated member 23 supported on a perforated sheet metal member 21 resting upon the metal casing 7 on the table 5. The casing 7 is formed with ridges 20 and drainage holes 14. The table 5 may be raised and lowered in the tank 2, and the chamber 13 may be connected to suction to form the diaphragm in the bath and to drain or dry it after removal from the bath, or to pressure to aid in transferring the diaphragm to a suction box before drying. The cap 27 is afterwards cut away, and the part 26 is slit at 30, Fig. 4, expanded on a cylindrical mandrel 21, wound with the coil 33 and secured in the cylindrical shape by glue, collodion, &c. The Specification as open to inspection under Sect. 91 comprises also two modifications, Figs. 6-11 (not shown), in which the coil support is moulded cylindrical and the cylindrical part of the reticulated member 23 is separate from the conical part and is made in sections or as a split cylinder, to facilitate removal of the diaphragm. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to centrifugal separator
IPC: B04B1/18
Filed: 1935-02-08
Abstract: 451,251. Centrifugal machines. FAWCETT, H. W., 3, Kent Road, Harrogate. Feb. 8, 1935, No. 4069. [Class 23] The peripheral discharge apertures of a centrifugal separator have rings b mounted to form a sliding fit therein, so that, when the separator is operating, each ring moves outwards under the influence of a spring or of centrifugal force, to form a tight joint with a seating surface S placed round the separator. The separator has liner plates A<1> from which the material passes to the valves V formed by the rings b. The seating surfaces S are carried by a sleeve B the upper part B<1> of which is formed as an hydraulic cylinder containing a piston C integral with the bowl wall A. The parts are normally in the position shown in Fig. 1. When liquid is introduced into the cylinder through the port E above the piston, the cylinder is raised until the port P in the sleeve registers with the valve V and so permits discharge from the bowl. When liquid is passed through the port F beneath the piston, the cylinder moves down again to the position shown in which the valve V is closed. A valve construction is shown in Fig. 2. The ring b slides in a housing a screwed into the bowl wall A, and is surrounded by a flexible packing sleeve c which maintains a tight joint under pressure exerted centrifugally by the sleeve d. The port P is formed by a renewable nipple g screwed into the seating plate f and the sleeve B. Stops l prevent the valve from being forced too far inwards. In a modification the packing ring is arranged behind the ring b.

Title: Improvements in apparatus for photographing nuclear fuel elements
Inventor: ELLIS DAVID LLEWELYN
IPC: G21F7/06
Filed: 1960-02-04
Abstract: 906,932. X-ray photography. HOBSON Ltd., H. M. March 22, 1961 [Feb. 4, 1960], No 4080/60. Class 98 (1). In apparatus for X-ray photography of a nuclear fuel element, a film or plate is mounted in a drum having a radiation-absorbing core, so that in one position the film is shielded from the element by the core, the drum being rotatable into another position in which the film is not so shielded (i.e. is presented for exposure). In the form shown, the fuel elements are stored in a chamber 10, one wall 11 of which can be moved to allow transport of an element 21 into the photography compartment 12 by a manipulator 22. Here it is supported between the X- ray head 16 and the drum 18 which carries the film cassette. The drum is mounted for rotation within a lead shielding wall 19, which also encloses a compartment 20 for containing the controlling apparatus. The drum is rotatable on a stationary radiation-absorbing core 27, and is operated by a torsion bar 28 passing through a central cavity and attached to the drum by an arm 29. The other end of the torsion bar terminates in a worm gear arrangement 30, 31 and a hand wheel 32. The cassette containing the film is introduced into a pocket 25 in the drum. Normally the drum is in such a position that the cassette is on the opposite side from the element 21, and so protected from its radiation by the core 27, as shown in Figs. 1 and 4. When a photograph is required, the drum is rapidly turned through 180 degrees so as to bring the cassette directly under the element, the head 16 energized to make an exposure, and the drum rapidly rotated back again. Fig. 5A shows in more detail a fluid pressure system for controlling the movements of the drum and operating the X-ray exposure. A system of levers and toggle linkages 36, 38 control a roller 35 which enters a detent notch 33 or 34 to hold the roller in either the exposure or non-exposure position. The linkage system is actuated by a fluid-pressure-operated piston 40, which controls the movement of the drum imparted by the torsion bar 28, and at the appropriate moment closes a contact 48 which switches on the X-ray tube for a predetermined time.

Title: Improvements in or relating to breech mechanism for guns
Inventor: HESELTINE JOHN CHAPMAN WHALEY
IPC: F41A5/32
Filed: 1948-02-12
Abstract: 790,990. Ordnance. VICKERS-ARMSTRONG (ENGINEERING), Ltd. Jan. 27. 1949 [Feb. 12, 1948], No. 4158/48. Class 92 The sliding breech-block 1 of a gun receives its translational movements directly from a hvdraulic ram and cylinder system 22, 26, thereby avoiding the, necessity of employing the usual crank mechanism. The cylinder shown is located in the breech ring 61 and has ports 29, 30 to which pressure fluid can be supplied by pipes 66, 67, leading to a valve control device 50; pipes 64. 65 for the supply and exhaust of the hydraulic media also lead +o the device 50. When the valve stem 51 is lowered by a hand lever 83 both ports 29, 30, are connected to exhaust and the breech-block can then be opened by rack and pinion mechanism 58, 59. upon the rotation of a hand lever on a shaft 60. With the valve stem in the raised position the power means can be brought into operation by the rotation of a hand lever 53. Such rotation causes a plate 90, by its nose 89 to give a.still further lift to the valve stem, the stem being subsequently held in the raised position by a latch 56 while. the, nose 89 is made to swing clear of the stem. The ram 22 is now moved by fluid pressure to the right, Fig. 2. the first effect of this being to impart a slight rotation to a two armed lever 39A pivoted at 35 to a beam 21 secured to the breechblock. The other arm of the lever thus causes an inward movement of a rod 42 mounted in the breech-block and the rod in turn releases a breech-block locking device 7A and also retracts the firing pin. Continued movement of the ram opens the breech-block.. As the latter nears its open position it actuates a lever 91 to remove the latch 56 from the valve-stem 51, and the latter now returns to the lower of its two raised or "power-on" positions. This enables pressure fluid to be supplied to port 30, and port 29 to be connected to exhaust whereby the ram moves the breechblock to the closed position. A cam 103 may be used to rotate the lever 53 when a semi-automatic action is desired. A further hand lever 45 pivoted on the beam 21 can be used to move the rod 42 to the breechunlocking position, when it is desired to open the breech by hand. Springs 33 serve to buffer the movements of the breech-block. Firing is effected electrically, and in Fig. 3 (not shown) is illustrated means for shrouding contacts in the circuit one at 14, Fig. 1, on the breech-ring and one at 15 on the breech-block. Specification 790,989 is referred to.

Title: Improvements in and relating to the production of pipeless ingots
IPC: B23P6/00
Filed: 1938-02-10
Abstract: 510,963. Castings ; welding by fusion. KELLOGG CO., M. W. Feb. 10, 1938, Nos. 4260 and 4261. Convention dates, Feb. 10, 1937, and Aug. 28, 1937. [Classes 83 (i) and 83 (iv)] Pipes in ingots are filled by electrically depositing weld metal beneath a blanket of flux. An electrode 17 is preferably fed at a predetermined rate by the usual welding head 19 and the voltage maintained while an amperage up to 10,000 per inch diameter of electrode is supplied, this being reduced as the cavity is filled to allow the deposited metal to solidify and avoid the formation of a pipe therein. The ingot, preferably still molten at the pipe, or the electrode may be rotated or oscillated during the process. The electrode should be of such a composition, or have such constituents in its coating or fed separately, that the deposited metal is of the same composition as the ingot. A non-gassing flux should be used ; such as manganese, aluminium, iron, alkaline earth, or other silicate or an aluminate or titanate or the constituents thereof, slag from the manufacture of chrome iron or from a steel finishing furnace. The flux may also include ferro-silicon or other constituent to facilitate the production of the desired deposit. In a modification a number of, preferably two, electrodes are used and these are preferably connected in series to produce an arc struck directly from one to the other or from each to the ingot. If desired metal is supplied separately, in solid or molten form. It a hot top is used in casting an ingot its volume should be only 5 per cent. of the whole ingot and the pipe need only be filled to the crop line. The Specification as open to inspection under Sect. 91 comprises also the use of the process for castings other than ingots, for filling surface cracks, and porous areas in metal bodies. In repairing cracks &c. the metal immediately surrounding the imperfection is removed by chipping, grinding, &c. and the cavity filled as above. Before closing the circuit the end of the electrode may be spaced from the body by an arc starter and be covered with flux. The heat should be sufficient to fuse the walls of the cavity. In another modification a carbon or other substantially non-destructible electrode may be used. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to basic refractory materials
IPC: C04B35/043
Filed: 1944-03-09
Abstract: Basic refractory materials contain a fine and a coarse fraction, the former having been burnt with a stabilizing-agent to a temperature exceeding 1500 DEG  C. to produce a dense substantially non-hydrating clinker which is ground to at least 40 mesh and of which the major portion passes 200 mesh, and the latter, which constitutes the majority of the mix contains a major portion at least as coarse as 28 mesh.  The fine fraction is prepared from finely-ground magnesite, magnesia, serpentine, talc, silica, dolomite, or limestone and is mixed with a dead-burning agent as described in Specification 450,961; if a magnesia refractory is being used, the stabilizer is preferably chrome ore and iron oxide such as mill scale or pyrites residue, in amount from 0.3-7 per cent, preferably 1-3 per cent, each of chromium and iron, while if a lime refractory is made, a phosphate is employed as stabilizer.  The mixture is burnt at 1500-1700 DEG  C. until the ingredients have combined, the resultant having a hydration value of under 4 per cent.  The product is ground so that substantially all passes a 40-mesh and preferably a 100-mesh screen and approximately 50 per cent will pass a 200-mesh screen, and is mixed with the coarse material which is preferably of the same composition as the fine material.  A suitable binder, such as goulac, molasses, sulphuric acid, sodium silicate, hydraulic cement, or the like is added; preferably a dry binder, e.g. sodium silicate, is ground with the fine fraction.  The material is gauged with water.
