Title: Drive and steering mechanism for vehicles
Inventor: SIREN ANDREW OSKAR
IPC: B62D61/12
Filed: 1969-07-03
Abstract: 1,261,436. Differential drive for steering. A. O. SIREN. 3 July, 1969, No. 33562/69. Heading B7H. [Also in Division F2] In a combined variable-ratio drive and differential steer arrangement for an amphibious vehicle, a pair of expanding pulley gears have driving pulleys 19 splined on a common input shaft 17, driving through V-belts 20 complementary pulleys 21 on separate aligned halfshafts 22 driving wheels on opposite sides of the vehicle, so that by adjusting the gears simultaneously in opposite directions, by turning a steer-wheel 31, the vehicle is steered, whilst adjustment in the same direction by a lever 77, Fig. 6, provides drive-ratio adjustment and declutching, with the belts resting on idler rollers 85 at maximum opening of the input pulleys 19.  In each gear the pulley flanges of both the input and output pulleys are simultaneously and positively adjusted axially in opposite directions by levers 38, 55, secured to meshing toothed wheels 54 for opposite swing, the inner levers 38, 38A being of T-form with transverse arms 39, 39A respectively (overlapped in the equalized position shown), attached at their remote ends 42, 42A to endless chains 41, 40, one crossed, tracking idle sprockets 34 on a bar 35A, and sprockets 32 on a steer-shaft 33 carrying the steer-wheel 31, turning which latter thereby adjusts the gears oppositely for steering the vehicle. Equalized adjustment for clutching and ratio shift is as follows. The steer shaft 31 is carried vertically on a longitudinal bar 74, Figs.. 3 and 6, slidable in a fixed guide 75, and carrying at its other end the idler-sprocket bar 35A. Sliding the bar 74 longitudinally by the ratchet-held lever 77 carries the entire chain and sprocket assembly with the bar, thus effecting equalized adjustment of the pulleys. Whip of the drive belts 20 is prevented by a pair of rollers (92), Fig. 7, not shown, pressed against the outer surface of the upper run of each belt by a common spring (90) acting through a roller-support beam (87). The gear input shaft 17 is driven by a chain 16, Fig. 2, and each half-shaft 22 drives through one chain 24 a ground-engaging wheel 11, and through a chain 26 a second ground-engaging wheel 11A, which latter drives through a chain 29 a third and foremost ground-engaging wheel 118 arranged slightly higher than the other two, to pack snow ahead of the other wheels and to facilitate planing in water.

Title: Improvements relating to remote control of electrically actuated apparatus
IPC: B61L1/18
Filed: 1922-12-13
Abstract: 210,586. Peter, B. H., Peter, L. H., and Westinghouse Brake & Saxby Signal Co., Ltd. Dec. 13, 1922. Electrical systems, automatic.-In a system in which the brack rails are in block sections separated by insulated joints and serve as conductors for the signalling current, the source of current and the signalling relay or equivalent device are connected to the transmission conductors (either in series or parallel) at one end of the conductors, the other ends of which are cross connected through a resistance, condenser, or inductance adapted to maintain the normal character of the current traversing the relay under normal conditions. The relay is arranged to give a safety signal when traversed by normal current, and to give a danger signal when the current varies from the normal in magnitude or character whether the variation results from a fault in the continuity of the transmission conductors or from the conductors being bridged, as by the wheels &c. of the vehicle, so as to short-circuit the resistance &c. in the cross-connection. Fig. 5 shows track rails 1 in sections separated by insulated joints 2. The rotor 11 of a signalling relay is connected across the entrance end A of the track rails in series with the secondary of the transformer 12. The primary of transformer 12 is connected in series with a relay winding 9 to a source of alternating current through leads 10. The exit ends C of the rails 1 are connected through the primary of a transformer 13, the secondary of which is in circuit with a condenser 8 adapted to give a definite normal phase-relationship between the currents in the relay windings, whereby the signal S is normally at " safety." Disturbance of this phase-relationship either by a break in the conductors or by a vehicle short-circuiting the connection at C results in the signal S being moved to " danger." The transformer 13 may be omitted and the rails at C connected directly through a condenser. A modification is described in which the coil 9 and the primary of the transformer 12 are connected to leads 10 in parallel. A further modification is described using a source of direct current in series with the relay, the connection at C being through a resistance.

Title: An improved process for making compounds of sulphhydryl keratinic acid and similar reduced degradation products of keratin with organic compounds containing arsenic
IPC: A61K38/01
Filed: 1934-11-27
Abstract: Compounds of sulphhydrylkeratinic acid with organic compounds containing arsenic are obtained by treating neutral or weakly alkaline solutions of keratinates or non-dialysable keratoses obtained by the hydrolytic degradation of keratin with acid, with hydroxy arsenobenzene derivatives, which simultaneously reduce and combine with the sulphhydryl groups, and separating the products with an organic precipitant.  Specifications 370,295 and 412,366 are referred to.  According to examples, keratinates obtained by the degradation of keratin in acid solution are treated with 4 : 4<1>-dihydroxy-3 : 3<1>-diaminoarsenobenzene, and 4 : 4<1>-dihydroxy-arsenobenzene, in neutral or weakly alkaline solution, in such quantities that the sulphur contained in the keratinate used is slightly in excess of one molecular proportion per molecular proportion of arsenic in the derivative used, and the products are isolated by precipitation from methyl or ethyl alcohol.

Title: Improvements in coke-ovens
IPC: C10B5/10
Filed: 1922-12-15
Abstract: 190,491. CoppÚe & Co., E. Dec. 15, 1921, [Convention date]. Void [Published Sect. 91 of the Act]. Coke ovens.-In a vertical-flued coke oven having regenerators beneath and parallel to the ovens, the flues in one half of the length of a heating- wall are connected to their supply and exhaust passages independently of those of the other half of the wall. the regenerator beneath the oven being correspondingly divided into two pairs of chambers, so that the heating can be independently controlled for the two halves of the oven. In the oven shown which can be heated at will either by preheated poor gas, rich gas, or both simultaneously, the two regenerator chambers 22, 27 can be connected by the passages 25, 29 either with a poor gas main 23, or a flue 1, which acts alternately as an air supply and an exhaust flue. The chambers 4', 10<1> similarly communicate through passages 2', 11' with a flue 1<1> having the same functions as the flue 1. For the two adjacent ovens these connections are reversed, as shown in Fig. 12, the pairs of chambers 22<1>, 27<1> and 4, 10 corresponding in position with the pairs 4, 10 and 22, 27, being connected respectively with the conduits 23<1>, 1', and with the conduit 1, and this alternation is maintained throughout the battery. At their upper ends the chambers 4, 10, 4<1>, 10' are connected to half sole flues 5, 5<1>, and the chambers 22, 27, 22<1>, 27<1> to pairs of half sole flues 26, 26<1>. Assuming that poor gas is being supplied through the main 23, and air through the flue 1 the operation is as follows. Gas is supplied to the chambers 22, 27, and air to the chambers 4, 10, and these supplies pass through the respective half sole flues 5, 26 at the two ends of the oven to the vertical flues 6, 14, where combustion is effected. The products are exhausted through the flues 61, 141, 51, 26<1> and the regenerators 4<1>, 10<1>, 22<1>, 27<1> to the flue 1'. Rich gas may be supplied through the pipes 9, 19, and when the gas is used alone the whole of the regenerator chambers are used for heating air. An oven embodying the same general arrangement of regenerators, heating flues, and supply and exhaust connections, but adapted for the use of rich gas only, is described in the Specification.

Abstract: 795,297. Two - - way transmission. STANDARD TELEPHONES & CABLES, Ltd. Nov. 9, 1956, No. 34299/56. Class 40 (4). In a carrier system using different frequency bands for the two directions of transmission a repeater is of the type in which a single amplifier 10 is traversed by both frequency bands in the same direction, one transmission path (1-2) passing through a high-pass filter 3, amplifier 10, and a high-pass filter 8, while the other transmission path (2-1) passes through a low-pass filter 5, amplifier 10, and low-pass filter 6; feedback across the amplifier 10 over the parallel paths provided by filters 8 and 5 and filters 6 and 3 being minimized by reversing the phase of the feedback in one of the paths. Feedback over filters 8 and 5 suffers phase inversion at a transformer 7, a transformer 4 in the path of filters 6 and 3 preserving a balance. The transformers may form part of the filter networks. Reference has been directed by the Comptroller to Specification 773,093.

Title: Improvements in and relating to sound record film printing apparatus
IPC: G03B27/46
Filed: 1928-11-22
Abstract: 300,996. British Thomson-Houston Co., Ltd., (Assignees of Kellogg, E. W.). Nov. 22, 1927, [Convention date]. Feeding webs.-A method of printing a photographic film record on to another film, particularly applicable to the production of a combined sound record and motion picture film, consists in limiting the area being printed at any instant to a narrow band and moving the record film and print film by means of smooth rollers whose speeds are free from appreciable fluctuations. In the apparatus shown, a negative sound record film 1 is drawn from a reel 2 and wound upon a reel 3, the film being moved by means of a friction drum 30 driven by an electromotor 28 and associated with a fly-wheel, and by a sprocket 26 driven by a motor 25. The speed of the motor 28 is automatically controlled by a rheostat 36, of any suitable type, having an adjustable arm 37, the position of which is governed by the size of the film loop between the drum 30 and the sprocket 26. A similar arrangement is used for the sensitized film 4 on which the print is to be made, and which may or may not have a picture record thereon, the motor 25 driving both sprockets 26, 27 for the films 1, 4 respectively. Both films are drawn over oppositely-disposed narrow slits 17, 18 in a printing device consisting of a casing 14 into which light passes from a source 19, a collecting lens 21 being preferably used. A lens 22 may be arranged within the casing, but may be dispensed with if the interior of the casing is covered with light-reflecting material. When the lens 22 is used, it is preferably placed slightly out of focus, to assist in preventing a grainy quality in the print. The means described in Specification 295,378 may be adopted for enabling the lengths of the film loops to control the speeds of the drums 30, 31. An alternative method is to utilize the tension in the film between the sprocket and drum to control the speed of the latter. This may be done by passing the film over an idler roller, spring-mounted between the sprocket and the drum, and causing the film to drive the drum, which is associated with a fly-wheel, and has an auxiliary drive if necessary. The idler mounting may be provided with a dashpot to prevent " hunting," or damping means may be provided on the drum shaft for this purpose. Such damping may be effected by mounting a copper disc on the shaft, and causing it to move between magnet poles. The magnets may be rotated slightly faster than the drum, so as to constitute, in addition, an auxiliary drive.

Abstract: 1351686 Blends comprising segmented ethylenic polymer siloxane polymers DOW CORNING CORP 22 July 1971 [25 Aug 1970] 34440/71 Headings C3P C3G and C3T A blend comprises (A) an ethylenic polymer, (B) a polydiorganosiloxane, and (C) a block or graft copolymer of segments of polymers of classes (A) and (B) above. The blends may be incorporated in further quantities of the (A) type component. The blends may be obtained by (1) simple blending of the preformed polymers, (2) polymerizing an ethylenic monomer to form (A) in the presence of preformed (B) and a preformed block copolymer (C) or (3) polymerizing an ethylenic monomer in the presence of preformed (B) and of a polysiloxane precursor for (C) containing reactive groupings to simultaneously form components (A) and (C) the latter by grafting the ethylenic monomer along the siloxane chain or by grafting terminally reactive polysiloxane along the forming chain of polar ethylenic monomer units. Examples of each of these procedures are provided, in which (1) polystyrene, a styrenedimethylsiloxy block copolymer, and a trimethylsiloxy end-blocked polydimethylsiloxane are blended in toluene, and of (2) polymerizing styrene in an aqueous mixture including benzoyl peroxide, sodium carboxymethyl cellulose, an optionially trimethylsiloxyterminated-polydimethylsiloxane, and a styrene-dimethylsiloxy block copolymer, and (3) polymerizing styrene, styrene/acrylonitrile, vinyl chloride or methyl methacrylates as in (2) above but replacing the block copolymer with a dimethylsiloxy-methyl vinyl siloxy copolymer or a mercapto terminated polydimethylsiloxane to produce the two types of polymers (C) and the polymers (A) in situ. In some cases mono- and di-sodium phosphates are included in the polymerization recipes and appropriate blends are added to further polystyrene.

Title: Improvements in and relating to the manufacture of can bodies having a solder bonded side seam
IPC: B23K1/16
Filed: 1937-12-13
Abstract: 502,925. Making can bodies. FARRER, J. O. (Continental Can Co., Inc.) Dec. 13, 1937, No. 34507. [Classes 83 (ii) and 83 (iv)] Seamed joints.-A soldered lap, lock, or combined lap and lock seam in the side of a can body is made by first coating the edge portions of a flat sheet metal blank with solder, then applying to the remainder of the blank a non-metallic coating which overlaps the solder layers leaving sufficient solder exposed to form the joint, then shaping the blank and then applying heat to melt the solder. The coatings may be applied to a single blank, or to a sheet which is subsequently cut to form a number of blanks. A sheet 1 to form a number of blanks is first coated on the side which is to form the outside of the body with solder at 2, 3 and 4 and the rest of the surface is then provided with a lithographed coating 7 which overlaps the solder layers. The side which is to form the inside of the body is similarly solder coated and the rest of the surface then coated with lacquer 8, Fig. 5, so as to leave complete layers of solder 9a, 10a on one edge and exposed solder portions 6b, 9b on the other edge. After cutting the sheet along the lines a, b to form blanks, the blanks are notched and slitted at the ends so as to form hook portions and lapping portions. The sheet is then shaped into body form and the lock seam is formed and heating applied, to effect the soldering. In the lock seam portion the lithographic coating 7 extends over the outer wall and up to the point 7a, Fig. 8 of the seam, and the inner lacquer coating extends to the point 8a of the seam. The lacquer remains on the inner face of the lap portions 5a. The lithographed and lacquered surfaces may terminate short of the seam leaving part of the solder exposed. The blanks may be formed from black plate either bare or coated with tin or other metal. When using uncoated black plate, oxide is first removed by hydrochloric acid or other acid flux.
