Title: Fibre-reinforced non-ferrous pressure-welded mouldings
IPC: C22C47/04
Filed: 1975-08-06
Abstract: 1499383 Making fibre reinforced metallic articles FELTEN & GUILLEAUME CARLSWERK AG 6 Aug 1975 [20 Sept 1974] 32834/75 Heading B3A [Also in Divisions E1 and F2] A fibre reinforced non-ferrous pressure-welded moulding 1 comprises high-tensile fibres 2 of plastics material precoated with aluminium, lead or tin or alloys of these metals and embedded in a metal matrix consisting of an elongated moulding of aluminium, lead or tin or alloys of these metals, the resulting composite product having been compacted by extrusion and then moulded. The fibres 2 are of an aromatic polyamide and are coated with lead or tin, which metals can be moulded at about 200 C., thereby not impairing the strength properties of the fibres. In view of the higher moulding temperatures of about 500 C. when using aluminium or aluminium alloy as the matrix material, the coated fibres 2 receive an additional bonding layer 3 of nickel, ceramics or plastics. The fibres may be formed into a bundle consisting of parallel fibres and wires of matrix material, some of which may be stranded together. A number of bundles may be welded together by extrusion prior to moulding. The reinforced members may be used to make lattice structures for cranes, overhead line systems, aerials, trollery electrodes, bearings, armouring wire for cables and wave guides.

Title: Generation of hadamard transforms of electrical signals
IPC: H04L23/02
Filed: 1972-07-12
Abstract: 1366085 Digital transmission; coding BRITISH BROADCASTING CORP 12 July 1972 [13 July 1971] 32837/71 Heading H4P A signal such as a T.V. signal is coded for transmission using Hadamard transforms. The simplest Hadamard matrix is of the order 2<SP>1</SP> and is given by the next being of order 2<SP>2</SP> and given by and so on. The image to be coded is divided, by scanning, into a series of 16 elements A to S in the described embodiment and each element A, B, &c. consists of a binary number which has m(=4) bits and which represents a different sample of the image. A corresponding 16 x 16 Hadamard matrix can be produced from these 16 elements (and is given at Y in the Table in the complete Specification). The circuit illustrated produces at Ya signal element a, b, &c. for each row of the matrix, wherein a to s together represent the Hadamard (H16) transform of the input elements A to S. The first of the four stages (i=4) of the circuit consists of two 8-position shift registers 12, 18; the output signal of the first 12 having the input signal U (A to S) subtracted from it at 16 (the difference being fed to the second register 18), and added to it at 14, the sum being fed direct to a switch 20. The switch 20 is controlled by T4 to pass sequentially to V firstly the 8 sum elements from 14 (A+J, B+K, &c.), and secondly the 8 difference elements from 16 delayed by 8 element periods at 18 (A-J, B-K, &c.). The second stage (i=3) operates similarly but with only 4-position registers whose capacities are increased by one bit. Each sum and difference operation now produces a 4-element term at W. Similarly, in the third and fourth stages the shift registers have only 2 and 1 stages respectively, with correspondingly increased bit capacities and the sum and difference operations produce the evaluations of the 8-element and 16- element terms, the resultant at Y being thus 16 rows a to s of elements each row being the evaluation of 16 elements (i.e. a 16 x 16 matrix). Provided that the Hadamard matrix is symmetrical it is shown that the image information can be retrieved at a remote receiver by taking a further Hadamard transform of the received signal Y. If the elements A to S were samples of an analogue signal, rather than binary words, similar operations can be carried out to achieve the Hadamard transforms by replacing the shift registers with analogue clocked stores (e.g. bucket-brigade type), and using analogue sum and difference circuits.

Title: Improvements in or relating to the production of tungsten and molybdenum carbides
IPC: C01B32/949
Filed: 1959-09-28
Abstract: <PICT:0890757/III/1> Tungsten or molybdenum carbides are prepared by contacting H2 with particles of tungsten, or molybdenum, oxide, a tungsten, or molybdenum, compound decomposable to oxide below the reduction temperature, or mixtures thereof, fluidized in a gas phase heated to at least 400 DEG C., initiating a flow of a carburizing gas into the gas phase when the bed is at least 800 DEG C., but before there has been any reduction of the oxide beyond the dioxide, and continuing the flow of carburizing gas and H2, while maintaining the bed at at least 800 DEG C., until the carbide is formed.  Oxides may be trioxides or dioxides, and compounds may be ammonium, tungstates or, molybdates, or molybdic, or tungstic, acids.  Carburizing gases are methane, ethane, propane, butane, ethylene, propylene, benzene, toluene, CO, natural gas, or town gas.  The oxide or compound is fed to reactor 1 heated by furnace 9 from bin 2 and fluidization of bed 7 is initially effected by He, A, Kn, or N2, or mixtures thereof entering through 4 and distributer 5 and withdrawn at 6 to remove air, and H2 is added subsequently. Alternatively, air may be evacuated through 6 before fluidization with inert gas or H2. Disengaging zone 10 and filters 11 remove entrained solid.  During reduction gases are withdrawn through 6, and methane is added at any time prior to, or during, reduction to the dioxide, or when this reduction is complete, as determined by monitoring the partial pressure of H2O in the exit gases.  During carburization temperature, 800-1000 DEG C., and pressure, atmospheric and 2 atms. are referred to, are controlled to prevent excess free C deposition, and gases may be recycled through 12.  To aid control a temperature gradient may be maintained in the bed, and methane may be added at intermediate points.  Carbide is removed at 16.

Filed: 1967-07-18
Abstract: 1,207,127. Change-giving. T. H. KETTERINGHAM. 18 Oct., 1968 [18 July, 1967], No. 33025/67. Heading G4V and G4X. A change-giving machine comprises a reciprocable slide, 24 and 26, Fig. 3, having an aperture 30 to receive a predetermined number of coins from a tube 16, Fig. 5, at one end of its travel, a plate 8 underlying the slide and formed so as to close the bottom of the aperture 30 when the slide is at one end of its travel, but not at the other end of its travel, in order to release the received coins, a lever 50 biased normally to co-operate with a stop 38 and lock the slide against movement towards the other end of its travel and pivoted on the slide (at 54), the lever carrying a coin bucket 58 which in response to the weight of a coin to be changed will swing the cantilever out of its locking position thus releasing the slide, and a stop 14 adapted to prevent the release of a coin of the correct size from the bucket until the slide approaches the other end of its travel, thus preventing premature relocking of the slide. Nine coin tubes of a detachable tube assembly pass through apertures 20 in a support plate 10, which holds them by their collars 22 with their ends lying in grooves 28 in the slides, Fig. 3. In the illustrated embodiment slides 26 and 24 change half-crowns and florins, respectively, into sixpences. Each aperture 30, which lies beneath a coin tube initially, may accommodate a plurality of coins. The slides are pulled forwards to bring their apertures above apertures 44 in the coins' platform 8 and deposit them in a tray. An entered coin from a tester falls down a shoot (72), Fig. 7 (not shown), where it is arrested by a projection (76) on the cantilever if another coin is present, tilting the cantilever. When the slide 36 is operated a projection 74 on the slide moves below the shoot to retain coins therein. Either the lever is stepped at 60, or the slide-locking stop 38 is stepped, such that as the slide moves outwards the lever arm 52 will drop and re-engage the stop 38 if the coin in the bucket 58 is too small or light. At least one coin tube is provided with a longitudinal slot 84, Fig. 5, through which projects an arm 88 of a coin-riding weight 86, which descends to engage an arm 92 and thereby either closing the coin entrance 80 or deflecting coins entered into a reject tray when the tube is empty.

The bed of pulverulent material is retained on a grid 4. The distributor 2' is bounded by an annular deflector 9 which prevents fluidisation of the peripheral portion of the bed. Alternatively, the grid 4 has an unperforated annular zone, as shown also at 5 in Fig. 5. In operation, circulating currents 6 are established in the bed and the vibrations which are applied in the direction of the arrows f by a vibrator 3 causes the treated granular product retained by the screen 7 to move up the surface of the latter and overflow at 8. In a modification, Figs. 3 and 4 (not shown), a screen and a deflector or an unperforated portion of the grid are provided at each lateral longitudinal side of a rectangular container. In Fig. 5, the screening means consists of an edged helicoidal perforated ramp 11 provided on the inner wall of a cylindrical container 10. A helicoidal deflector 12 is disposed below the ramp to return to the bed the pulverulent solid material passing through the perforations of the ramp. Vibrations are provided by two unbalanced motors 3. In a modification of Fig. 5, Figs. 7 and 8 (not shown) the central, instead of the annular, portion of the grid 4 is impermeable to fluidising gas. In all the embodiments heating of the fluidised bed may be effected by heating the current of fluidising gas or by withdrawing a fraction of the pulverulent solid material, heating it and recycling it. The bed of pulverulent solid material may be composed either of the product treated or of an auxiliary solid material. The apparatus may be used for chemically treating or coating granular products in a fluidised bed.
