Title: Improvements in or relating to means for battery charging in connection with engine electric transmission systems
IPC: H02P9/00
Filed: 1934-05-14
Abstract: 422,315. Systems for transmitting mechanical power; charging batteries. ARMSTRONG WHITWORTH & CO. (ENGINEERS), Ltd., SIR W. G., WATKINS, D. J., and SPAINK, J. H. ABBINK-, Scotswood Works, Newcastle-on-Tyne. May 14, 1934, No. 14565. [Class 38 (iv)] An engine electric transmission system comprises a generator G driven by a prime mover DE and adapted to supply a motor M and battery B, and during the idling speed of the engine DE the battery B is used to give additional excitation to the generator to raise its E.M.F. so that it can charge the battery. Contacts 1, 2, 3 control the excitation and a reverse current cut-out RCC is provided. When the motor M is being supplied, the contacts 1, 2 are closed and the field winding AF is energized by the generator. When the engine is idling the contacts 1, 2 are opened and contact 3 closed, so that the battery B is connected to the winding AF. Although the armature of the generator is running slowly the energization is increased and the E.M.F. of the generator G will be higher than that of the battery B. Resistances R1, R2 permit adjustment of the excitation. In Fig. 2 (not shown) a separate winding is provided for the added excitation by the battery.

Title: Color-cinematography
IPC: G03B33/00
Filed: 1932-05-23
Abstract: 402,113. Colour kinematography. KELLEY, W. VAN D., 6723, Santa Monica Boulevard, Hollywood, California, U.S.A. May 23, 1932, No. 14601. Drawings to Specification. [Classes 97 (i) and 98 (ii).] A positive film is made from a pair of colourcomponent negatives, alternate frames of the positive being made from the respective negatives, and one series of frames only being tinted corresponding to one colour-component, the positive being projected at twice the normal speed. The frames of the positive may have half the standard height, and the uncoloured series of frames may be slightly fogged, or have lines printed thereon, or have a partially opaquing tint applied. The negatives may be made by exposing alternate frames through complemental colour filters, from superposed sensitive emulsions, one sensitive, the other insensitive, to red, or by using a double or triple film for simultaneous presentation to the lens. The positive may be made by using stock coated with a dye insoluble in the developing baths. When developed and fixed, the colour-component frames corresponding to the dye colour are coated with a colourless transparent waterproofing material, and the dye is bleached out of the other series of frames. The positives may also be made by coating alternate frames with a coloured transparent waterproof coating material. The films may carry a sound record, from which the colour is bleached out. Among the dyes that may be used are benzopurpurine, congo-red, erioglaucine and neptune green SGX. Suitable bleaching solutions include sodium peroxide or sodium hydrosulphite. The solution for waterproofing the coloured portions may comprise celluloid dissolved in amyl or ethyl acetates.

Title: Improvements relating to combined electric switch and fuse gear
IPC: H01H9/10
Filed: 1931-05-18
Abstract: 373,402. Snap-action switches. DOBSON, E. and FOSTER ENGINEERING CO., Ltd., Apex Works, South Wimbledon, London. May 18, 1931, No. 14637. [Class 38 (v).] A double pole switch-fuse has contact blocks on the base adapted for engagement by the clips of fuse holders carried by the cover thus ensuring that the fuses are disconnected when the cover is removed. The switch comprises a moulded insulating case 1 in which is mounted an insulating contact spindle 3 having a bearing in the casing at one end 6 and formed at the other end with a spigot which engages a central recess in a handle 4 which also has a bearing in the casing. U-shaped movable contacts, embedded in the contact spindle, co-operate with contacts on the base which are connected to contact blocks. Two pairs of these contact blocks are adapted to engage with the clips 13 of fuses which are passed through tunnels 18 in ridges on the insulating cover 2, which is held in position by a screw 19. On removal of the cover the fuses are thus disconnected. The snap action mechanism (not shown) comprises a spring coiled round the spigot end of the contact spindle and having its ends engaged by projections on the handle and spindle so that movement of the handle is transmitted to the spindle. A spring pawl 23 engages a recess in the spindle 3 to hold it until the spring is sufficiently strained, when a cam on the handle lifts the pawl, allowing the contact spindle to move rapidly. A projection 29 on the spindle 3 engages fixed stops on the casing to limit the movement of the spindle. Hooks or stumps may be provided on the lid to engage the movable contact member to lock the casing while the switch is on.

Title: Improvements in or relating to folded slot aerials
Inventor: CARY REX HENRY JOHN
IPC: H01Q9/26
Filed: 1951-06-20
Abstract: 708,008. Aerials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 5, 1952 [June 20, 1951], No. 14678/51. Class 40 (7) Relates to folded slot aerials of the type comprising an elongated aperture 1 in a conducting surface 2 enclosing a centre conductor 3 disposed substantially in the plane of the conducting surface and having adjacent feed points A and B located on the centre conductor and the boundary of the slot respectively. According to the present invention the bandwidth of such an aerial is increased by making the reactancefrequency characteristic of the impedance looking in at the feed point towards the left-hand of the slot different from that looking in towards the right-hand. This is effected by marking the aerial unsymmetrical with respect to the feed points by (1) displacing the feed points a distance l from the centre as shown in Fig. 3, (2) filling the slot on one side of the feed points with dielectric, Fig. 4 (not shown), (3) marking the two portions of the centre conductor of different width, Fig. 10 (not shown), (4) marking the transverse dimensions of the slot different, Fig. 5 (not shown), (5) inserting series lumped or distributed reactance in one portion of the centre conductor, Fig. 6 (not shown), which may be extended to join the end boundary of the slot, Fig. 7 (not shown), (6) connecting one end of the centre conductor to the adjacent end boundary of the slot directly, Fig. 8 (not shown), or via a reactance X, Fig. 3, (7) connecting one or both ends of the centre conductor to the surface 2 beyond the end boundary of the slot, Fig. 9, (not shown). Any suitable combination of the above methods may be employed and in any of the embodiments the impedance may be adjusted by displacing the centre conductor from the centre of the slot as illustrated in Fig. 13, which shows a slot backed by a cavity resonator whose boundaries are indicated at 5, the slot being folded to provide a non-directional radiation pattern. Fig. 11 and Fig. 12 (not shown) illustrate a slot cut in the conductor skin 2 of an aircraft and covered on the inside with a sheet of dielectric 4, the centre conductor comprising two portions 3A and 3B of unequal length and thickness, the thick portion 3A being in contact with the dielectric and the thin portion 3B being spaced therefrom by supports 4B so that the effective dielectric constants for the two portions of the central conductor is also different.

Title: Improvements in and relating to the production of gears
IPC: B23F5/20
Filed: 1926-06-14
Abstract: 253,909. Gleason Works, (Assignees of Wildhaber, E.). June 22, 1925, [Convention date]. Gear-cutting.- The teeth of hyperboloidal gear wheels are formed by a generating process consisting in rolling the blank relatively to the path of the cutting-tool in the manner of a hyperboloidal gear wheel rolling on a helicoidal segment such as 20, Fig. 3. In one form of machine shown in Figs. 19 and 20 the cutting-tools 76, 77 for cutting opposite sides of a tooth reciprocate in a plane at right-angles to the axis 85 of a rotatable cradle 82 on which they are mounted. The blank 80 is mounted in a slide 87 which can be adjusted to offset the axis 85 of the cradle and the blank axis 81. The slide 87 is carried by a table 89 which can move in the direction of the cradle axis 85. The parts are interconnected by suitable driving mechanism and during operation the cutting-tools reciprocate, the cradle 82 and blank 80 rotate about the axes 85, 81 respectively and the table 89 slides in the direction of the axis 85, all movements being so timed as to impart to the tools and blank the desired relative motion. When the tools 76, 77 have been fed past the blank so as to complete one tooth the generating movements are reversed, the blank is withdrawn and indexed and the cycle repeated. Alternatively the blank may be indexed continuously. A single reciprocating tool only may be used. The path of the tools relatively to the cradle 82 may be circular the tools having forms as 48, 49, Fig. 12, or the teeth may be cut by a grinding operation by grinding-wheels such as 52, 53, Fig. 13. The sides of the teeth represented by the cutting-tool may be straight, Fig. 12, curved, or spherical, Fig. 13. The gears may be constructed so that the teeth lie outside the pitch hyperboloids. For large reductions the cone angles of intermeshing gears are preferably in predetermined relation to the longitudinal curvature of the teeth and may be proportioned according to the principles disclosed in Specification 251,953. As shown in Fig. 10, the basic segments 72, 73 represented by the tools 70, 71 for intermeshing gears may vary slightly from theoretical considerations and may not be strictly complementary. The invention is applicable to other forms of gears with non-intersecting axes as worm gears. The theory upon which the invention is based is included in the Specification.

Title: Control device for consecutive continuously variable adjustment of hydrostatic gears
IPC: F15B11/20
Filed: 1959-05-01
Abstract: 872,278. Hydraulic transmission of power. KAMPER-MOTOREN G.m.b.H. May 1, 1959 [May 24, 1958], No. 15011/59. Class 69(2). An hydrostatic gear consisting of a pump 18 and motor 19 is controlled by a'device which, when operated for increased output speed of the motor, shifts the pump output to a maximum rate of delivery while making it impossible for the motor to be shifted towards minimum consumption, and when operated for reduced output speed of the motor, adjusts the motor from low to maximum consumption before the pump can be shifted from a maximum to a minimum rate of delivery. The control device comprises a four-way slide valve 1 which is connected by lines 2, 3 to valves 4, 5, the positions of which are controlled by piston-andcylinder devices 6, 7 associated with the pump and motor, respectively. Each device 6, 7 is also connected to the valve controlled by the other device and is moved against a spring 16, 17 upon its associated pump being moved to a position of maximum output or motor being moved to a position of maximum consumption. When the pump is in an arbitrary position, the supply of fluid from the slide valve 1 passes through line 3, valve 5 and line 10 to the lower end of the device 6 to move the piston upwardly and increase the output of the pump, the motor being retained in a position of maximum consumption by non-return valves 12 connected to the lower end of the device 7 by the valve 4 and a line 8. The valve 4 is actuated by the device 6 when the pump reaches maximum output to permit the motor to be moved from its position of maximum consumption, the pump being prevented from moving from its position of maximum delivery by non-return valve 13 connected to the lower end of the device 6 by the valve 5 and a line 10. Reduced output speed of the motor is obtained by operating the slide valve 1 to connect the supply to line 2, valve 4 and the line 8 to the lower end of the device 7 and move the position of the motor to maximum consumption in which position the valve 5 is actuated to connect the lower end of the device 6 to an exhaust line and permit the pump to be moved towards the position of minimum delivery.

Title: Filleting machine
IPC: A22C25/08
Filed: 1943-09-16
Abstract: 572,935. Fish filleting machines. ATLANTIC COAST FISHERIES CO. Sept. 16, 1943, No. 15205. Convention date, Jan. 21, 1942. [Class 28 (ii)] Beheaded fish to be filleted are pushed tail first and back down towards pairs of rotating circular toothed knives and fixed filleting knives, the under circular pair of rotating knives slitting each side of the dorsal fin and the top pair slitting the belly, after which the fish is pushed against the fixed filleting knives 100 which act as described in Specification 452,688. Each fish is placed by hand in a feed trough, tail first which positions it belly upwards from which it is pushed by a chain of pushers 110 to a positioning trough where a fin guide channel receives the tail and dorsal fin and further positioning guides position the fish vertically. Swivel guides maintain this position. The fish then passes to a tiltable trough which feeds the tail between the rotating slitting knives by which it is propelled forward against the knives 100 whereby the fillets are cut off from each side of the skeleton. As the thicker portion of the fish is engaged by the knives this trough is free to tilt against a light spring so that the backbone and ribs are maintained at the usual level. Fig. 1 joined to Fig la is a plan and Figs. 2 and 2a follow an elevation. In operation, decapitated fish, tail first and back downwards, are placed into a feed trough 8. Pushers 110 on endless chains 114 engage the rear end of the fish and push it through the feed trough 8, Fig. 12, with bent up sides to make it assume a vertical position. The fish then passes on to fin guide plates 20 of a positioning trough 10 where the tail enters the channel 23 and later the dorsal fins also enter the channel. Continuing positioning guides 24 (tilting if necessary) positions the fish in a vertical direction. Swivel guides 27 retain the fish vertical. The guides 27 are urged together by springs and move in unison by engagement of their toothed segments 40. Pushers 110 then push the fish on to a tilting trough, Fig. 13, where a tail enters the channel 73 and positioning guides 75 and swivel guides 74 maintain the fish belly up. Guides 80 in this trough engage the tail and dorsal fin. Continued pushing by pushers 110 enters the tail into the vertical space between the pairs of knives 98, 96, which slit the back and belly. When the knives engage the thicker portion of the body of the fish the tilting trough tilts so that the backbone and ribs are maintained at approximately the correct level. When the fish passes the knives, springs 56 restore the tilting trough back into normal position. The action of the pushers 110 and of the rotating knives 98 at this point project the fish at high velocity on to filleting knives 100. An electric motor and gearing with a hand operated clutch provides the drive for a chain of pushers 110. A water spray to facilitate movement may be introduced into the first trough. The upper rotating knives 96 may be adjusted in a vertical direction.

Title: Improvements in or relating to artificial teeth
IPC: A61C13/10
Filed: 1923-06-11
Abstract: 208,090. Jackson, W. J. Mellersh-, (Dentists' Supply Co.). June 11, 1923. Teeth, artificial.-In an artificial tooth of the type in which a vertical hole opens through the top of the tooth and in which the crown surface of the tooth is notched between the hole and the lingual wall, the hole tapers from the bottom outwardly in a buccal-lingual direction, is closed on all sides at its lower part, and is roughly elliptical in horizontal section, the major axis lying in a mesio-distal direction; also, the depth of the notch is greatly more than the vertical thickness of the anchor which is fixed within the notch and serves to secure the tooth to the plate. The side walls of the notch may be undercut and may be made to taper horizontally. The tooth 2 provided with a hole 6 and notch 7 having the features above described is attached to the vulcanite plate 3 and secured in position by the anchor 4. The vertical portion 10 of the anchor 4 is of greater width than thickness; the rearward arm 13, which fits within the notch 7, may be bevelled so that it is wider at the bottom than at the top and may be made tapering horizontally, as shown. To afford greater security the vertical portion 10 may be grooved and the rearward arm 13 looped as at 12. This construction is stated to enable adjustment between the tooth and its support to be effected in making the denture. Adjustment of the anchor and plate relatively to the tooth may be effected by adjusting the position of the vertical portion 10 of the anchor relatively to the walls of the hole 6; similarly, adjustment of the tooth relatively to the anchor and plate may be effected by fixing the tooth so that the walls of the hole 6 occupy the desired position with respect to the vertical portion of the anchor.

Title: Improvements relating to the production of chlorine dioxide and chlorine
IPC: C01B11/02
Filed: 1940-11-28
Abstract: 546,282. Production of chlorine dioxide and chlorine. EVANS, C. H. Nov. 28, 1940, No. 15261. Drawings to Specification. [Classes 1 (ii) and 90] In preparing chlorine dioxide and chlorine by the action of sulphuric acid on sodium chloride and sodium chlorate in solution, a high proportion of chlorine dioxide to chlorine is obtained by first heating the solution of sodium chloride and sodium chlorate so that some evaporation occurs, and owing to the small increase of solubility of the chloride with temperature, some chloride separates out. The chlorine may be separated and re-cycled for treating caustic soda in the production of the solution, or the solution may be made by electrolysis of brine under conditions of acidity and temperature to hypochlorite formation, and maximize sodium chlorate yield. The solution may be reacted with half its volume of 70 per cent. sulphuric acid at 120‹ F. and sodium sulphate or bisulphate from the reaction may be recovered for use, after separation of excess sulphuric acid for reuse, volatile products having been scrubbed out. Specification 510,678 is referred to.

Title: Electrode for use in the electrolysis of aqueous acids
IPC: C25B11/12
Filed: 1959-05-04
Abstract: A bipolar graphite electrode has a solid, compact layer disposed within it to prevent passage of electrolyte through the electrode. The layer may be an acid-resistant cement, e.g. a phenol-formaldehyde resin, which unites two graphite sheets. Alternatively, a graphite electrode may be impregnated, after de-gassing, with an acid-resistant synthetic resin, e.g. a condensation product of phenol and formaldehyde, if desired with furfurol and epichlorhydrin, the electrode being then treated with a solvent, e.g. methanol, to render the external faces electrolytically active, the resin remaining in the electrode being cured.  The opposed external faces are interconnected by bolts, screws or cones of graphite impregnated with paraffin or by bolts of titanium or tantalum.
