Title: Mechanism for pulling an elongated article
IPC: B66D3/00
Filed: 1962-09-04
Abstract: 1,016,137. Conveying elongated members. UNIVERSAL MOULDED FIBER GLASS CORPORATION. Sept. 4, 1962 [Sept. 18, 1961], No. 33840/62. Heading B8A. [Also in Divisions B5 and F2] In apparatus for making elongated shapes of plastic materials viz. thermosetting or heat hardenable type containing reinforcing elements of glass fibre, metal wires, strips, angles &c. in which the material C (Fig. 1) is drawn from a heated bath R through a tapered die 23 in which it solidifies, the drawing means comprises a pair of opposed endless track assemblies yieldingly engaged with the work C by pneumatic cylinders and ram assemblies 76, 79. A pair of opposed endless track assemblies for drawing reinforced plastic and like material through a die are yieldingly engaged with the work by a pair of pneumatic cylinder and ram assemblies 76, 79, Fig. 3. Pairs of elongated guide plates 37, Fig. 4, guidingly support pairs of chains 39 carrying cross-connected gripping tread links 41, 43 forming the endless tracks for gripping the work. Each upper and lower conveyer assembly is floatingly mounted on a fixed frame 30 through pairs of parallel links 67, 68 and 74, 75 and are caused to move in unison, symmetrically of the work axis by links 81, 82 coupled to a common slide 83 guided at 84 in the frame 30. The cylinder and ram assemblies 76, 79 are connected at 77, 80 between the upper and lower pairs of guide frame plates 37. The endless conveyers are driven through sprocket wheels 51 mounted at one end of each conveyer assembly driven from a motor 86 through chain drives comprising a pair of contra-rotating sprockets 99, 100 so disposed on lines parallel to the links 67, 74 and at distances equal to the lengths of the links so that the chain drives 103, 104 are not affected by movement of the guide plates 37. A differential device 93 (see Division F2) is incorporated in the drive to balance out the load between the chains. The conveyer links are guided at the opposite ends of the guide plates 37 by adjustably mounted guide shoes 62 bolted as at 63, 64, Fig. 10, and movable endwise for chain tensioning by a grub screw 66. The guide shoes 62 are of irregular form having separate portions 62a, 62b, 62c of different radii which operate to take up the fluctuating changes in chain slackness which occur as the links pass between the guide plate 37 and the driving sprocket 51. The gripping tread links 41, 43 arranged across the chains have chain link engaging lugs 41a, 41b of different widths at opposite ends for engagement between alternatively disposed outer and inner links 39 of the chains. With each pair of chains arranged in staggered relationship a single form of tread link 41, 43 may therefor be used.

Title: Improvements in dirigible headlights for vehicles
IPC: B60Q1/124
Filed: 1929-11-09
Abstract: 342,021. Vehicle lamps. CALKINS, J. M., 1000, South West 12th Street, Miami, Florida, U.S.A. Nov. 9, 1929, No. 34265. [Class 75 (iii).] Directing.-In a headlight for vehicles having means for swivelling and tilting it simultaneously, the tilt is greater when the supporting arm is swivelled through a substantial range in one direction than when it is swivelled through the same range in the other direction. Thus, in the combination of a pair of such headlights, the swivelling of each headlight through equal substantial ranges in one direction causes one headlight to dip more than the other. The lamp is carried on an arm 4 which is pivotally connected by a pin 5 with the fork of a rod 7 which can be rotated in a tubular shank 8 by means of an arm 41 connected by a rod 40 with a quadrant which is rotated by a worm on the steering post. Rotatably connected in the fork 21 of the arm 4 is a finger 19 which traverses the cam surfaces on the rings 16, 17, 18 fixed in the casing 10, and is caused by them to move horizontally when the rod 7 is rotated and to tilt the arm 4 about the axis 5. The ring 18 has a lobe 22 whose sides 23, 24 slope away sharply and gently respectively, and a complementary recess 25 diametrically opposite. The recess is also formed in the rings 16, 17. The lobe is formed on a separated section 28 held in by a spring, to compensate for wear. The difference in the slopes 23, 24 produces a difference in dip according to the direction of rotation. A protuberance 30 is formed on the highest part of the lobe, extending over one half the depth of the ring, and a corresponding lug on one end of the finger 19, so that a slight deflection causes uniform dipping in either direction. In the pair of headlights, the sharp slopes 23 in the cams are situated adjacent to one another, and the gentle slopes 24 towards the outsides of the vehicle, so that when both lamps are rotated together, the lamp on the inside of the curve will be tilted more than that on the outside. The rotation of one lamp is imparted to the other by a link rod 43 pivotally connected to arms 44. In a modification, the lamp rod 7 is rotated by connection with an arm adjustably secured to the cross-tie of the steering gear, the worm and quadrant drive being thus dispensed with.

Title: Method for Converting Sulfur Dioxide to Sulfur Trioxide
Inventor: MANDELIK BERNARD GEORGE
IPC: C01B17/765
Filed: 1966-07-29
Abstract: 1,150,953. Sulphur trioxide. PULLMAN Inc. 29 July, 1966, No. 34290/66. Heading C1A. Sulphur trioxide is prepared from a mixture, comprising sulphur dioxide and oxygen, by passing the mixture in contact with a first oxidation catalyst at a temperature above its ignition point (above 750‹ F.) to convert a proportion of the sulphur dioxide to sulphur trioxide ; cooling (after the exothermic reaction) to a temperature below the ignition point of the first catalyst but above that of a second oxidation catalyst of lower ignition point; and passing the mixture in contact with the second oxidation catalyst at said temperature, to convert a further proportion of sulphur dioxide to sulphur trioxide. First oxidation catalysts may be platinum on a carrier such as asbestos, manganese sulphate, silica or silica and alumina; or platinum group metals, or vanadium pentoxide. Second oxidation catalysts may be produced by impregnating the first oxidation catalysts with between 0À5 and 3% by weight of a suitable metal oxide such as P 2 O 5  or MoO 3 .

Title: Improvements in a process for producing formates of alkaline earth metals
IPC: C07C51/10
Filed: 1930-11-14
Abstract: Alkaline-earth formates, including magnesium formate, are obtained by the action of carbon monoxide or gases containing carbon monoxide on alkaline-earth metal hydroxides at elevated temperatures and super-atmospheric pressure, in the presence of not more than about 30 parts, and preferably between 10 and 20 parts of alkali metal formates to every 100 parts by weight of alkaline-earth hydroxide. The alkali formate may be formed in situ by adding suitable parent substances to the reaction mass originally; examples of such substances are caustic alkalis, alkali phenolates, acetates, oleates, chromates, carbonates, sulphides, sulphates, alcoholates, ferrocyanides, and borates. Potassium salts are preferable to sodium salts.  The reaction may be effected in the presence of large amounts of water, sufficient alkaline-earth metal formate being added to the reaction mixture to form a saturated solution, so that the formate produced by the reaction is precipitated, the mother liquor being used again. Alternatively, the alkaline-earth metal hydroxide may be treated in the solid, preferably finely powdered form, in the presence of small quantities of moisture, which may be supplied to the reaction as water vapour.  Calcium hydroxide may be obtained in a suitable form as a loose powder by slaking lime in a current of steam, and in this case the heat of hydration can be utilized for the reaction with carbon monoxide.  The product consisting of alkaline-earth formate mixed with alkali formate is especially suitable for working up into formic acid by treatment with sulphuric acid.  Examples are given.

Title: Improvements in or relating to the protection of articles made of magnetic material
IPC: H01F1/18
Filed: 1953-12-09
Abstract: 739,402. Packaging. VACUUMSCHMELZE AKT.-GES. Dec. 9, 1953 [Jan. 12, 1953; Oct. 31, 1953; Oct. 31, 1953], No. 34328/53. Class 94 (1). [Also in Group XXXV] Articles consisting of a plurality of layers or laminations of magnetic material, e.g. wound strip cores, are protected during handling, transit or storage by applying a coating of insulating material in the liquid or semi-liquid state and causing or allowing it to solidify, the material when in the liquid or semi-liquid state having a sufficiently high surface tension to prevent it from penetrating between the laminations and, when it solidifies, producing no mechanical stresses in the article sufficient to impair its magnetic properties. The coating may be applied in the molten state by spraying, dipping or casting or may be pressed on when partially solidified, 'and may comprise several layers which may be of different materials and applied by different methods. For example, the outer layer or layers may have a high resistance to impact and the inner layer or layers may be of yieldable material. The outer layer may be resistant to chemical action, e.g. attack by oil. The coating may be reinforced by embedded plates, rings or other members made of a material, e.g. that known under the Registered Trade Mark "Pertinax" which does not soften appreciably at the temperature at which the coating is applied. Suitable materials for the coating are polymerized hydrocarbons having a chloro-naphthalene base mixed with polysterene or polyvinyl chloride, or ethoxyline resins. In an alternative method of protection, an adherent covering in the form of a large number of discrete drops is applied to all or part of the surface of the article, particularly the end surfaces of the laminations, by sprinkling a powdered thermoplastic insulating material, e.g. an ethoxyline resin, on the article, heating the article to melt or soften the powder and then cooling the article. Further layers of synthetic resinous materials may then be applied by dipping, spraying or casting, and these may be separated from the covering by an intermediate layer of elastic material, such as rubber, which is vulcanized after application.

Title: Improvements in or relating to clinometers and like instruments
IPC: G01C9/08
Filed: 1921-12-21
Abstract: 191,591. Alexander, F. H., and Gillie, J. W. Dec. 21, 1921. Clinometers; horizons, artificial. - In a pendulum clinometer acceleration effects are eliminated by the use of a main pendulum of relatively long period, a second pendulum of short period, and a magnetic force acting between them to oppose deflection of the main pendulum under acceleration influences. The main pendulum 1 carrying a magnet 3 is mounted within a casing 10 coaxially with the second pendulum 2 carrying a magnet 4, and the period of the pendulum 1 is variable by adjustment of a weight 5. Inclination is indicated by the position of a mark 11 on the pendulum 1 in relation to a scale 12 on the casing 10, and the position of a pointer 13 carried by the pendulum 2 in relation to a scale 14 on the pendulum 1 indicates the amount of the acceleration. Adjustable clearances are provided between the adjacent poles a, band c, d of the magnets 3, 4 both angularly as shown at 27 and in the axial direction. By adjustment of these clearances and of the weight 5 the magnetic turning moment on the pendulum 1 may be made to counteract the turning moment due to acceleration over a considerable range of acceleration values. Figs. 4 and 6 show in elevation and plan respectively a. modification in which the pendulum 1 is formed as a horizontal frame provided with balancing weights 5, 17 and carrying bar magnets 3 co-operating with magnets 4 on the pendulum 2. A datum line 15 combined with a collimating lens 16 is attached to the pendulum 1 for defining an artificial horizon. The pendulum 1 may carry a further magnet 18 to co-operate with magnets 19 carried by the pendulum 2 to cause alternate increase and decrease in the magnetic couple as the deviation from the normal of the pendulum 2 increases. The pendulum 2 may carry a further magnet to co-operate with the magnet 18 to centralize the pendulum 1 against frictional effect of the bearings. In a further modification shown in plan in Fig. 9, the pendulum 1 is supported in gimbals to enable it to swing in two directions at right angles, and a separate system of short period pendulums 2, 2<1> and co-operating magnets is provided for each such direction.

Title: Improvements in and relating to systems of control for low pressure turbines
IPC: F01K7/02
Filed: 1928-11-22
Abstract: 325,587. British Thomson-Houston Co., Ltd., and Collingham, R. H. Nov. 22, 1928. Motor power plant. - Relates to motor power plant, particularly for ship propulsion, in which a low pressure turbine 10 is supplied mainly with exhaust steam from a reciprocating engine 1, the supply being augmented by live steam when required. The reciprocating engine 1 drives an alternating current generator 25 which supplies power to an electric motor 26 on the propeller shaft. The turbine drives also a direct current generator 21 for ships lighting and auxiliary power. A bye-pass valve 4 controlled by an oil-pressed piston 6 is provided so that the exhaust from the engine 1 may be diverted to the condenser 9. The admission of high pressure fluid through the pipe 14 is controlled by a valve 13 under the influence of a centrifugal governor 17. During normal running, the alternator 20 being locked electrically with the motor 26, the speed of the turbo-alternator 10, 20, is determined by the speed of the main engines 1, and the valve 13 and governor 17 are inoperative. When manoeuvring of the ship is required, a lever 22 which is interlocked with the main engine stop valve and reversing levers, is moved to open the alternator field switch 23 to break the electric lock between the prime movers, and also to release the oil pressure under the piston 6 so that the valve 4 is actuated to divert the exhaust of engine 1 to the condenser. The turbine is now loaded by the generator 21, and its speed falls until the governor 17 becomes operative and controls the valve 13 admitting high pressure steam. The operation is reversed when normal conditions' are resumed. An emergency governor 19 stops the turbine at excess speeds when under control of the governor 17. If excess speed of the turbine is attained when working normally, an emergency governor 18 releases the pressure below the piston 6 and so actuates the bye-pass valve 4.

Title: Information transmission
IPC: H04J3/16
Filed: 1973-07-19
Abstract: 1437215 Signal transmission TELEFONAKTIEBOLAGET L M ERICSSON 19 July 1973 [19 July 1972] 34583/73 Heading H4P The invention relates to means for reducing redundancy in information transmission, e.g. of PCM-enooded telephone or TV signals. The information content of a channel is redundant if the signal corresponds to zero voltage (Figs. 3, 4, not shown) or if it does not contain any new information (Figs. 5, 6, not shown). As shown, telephone signals on 120 channels are fed via a PCM-encoder 2 to a code converter 3, from which an 8-bit PCM pulse train is transmitted to a code converter 4 and a PCM decoder 5. A PCM-decoder and a PCM-encoder may be included between converters 3, 4 and the signals transmitted in analog form (Fig. 9, not shown). In converter 3 the signals are fed via AND gates 31 to 120 shift registers 32 and are examined for redundancy by a circuit 33. A 0 or 1 marker bit is associated with the odd and even channels respectively, and either this bit or its complement is entered in each register according as the signal in the corresponding channel represents redundant or non-redundant information. The register contents are applied to AND gates 34 under the control of a circuit 35 which transmits only the marker bit if there is redundancy and transmits the marker bit followed by the PCM word if there is no redundancy. The same procedure is carried out in reverse in converter 4, each word being stored or reconstituted in shift registers 42 under the control of circuits 43, 44. A modification is described for use with transmitted TV signals (Figs. 7, 8, not shown). Provision may be made for reducing the word length so as to eliminate the least significant part of the information; 8-bit words are reconstituted in registers 42 by filling the missing bit positions with zeros.
