IPC: C01B31/00
Filed: 1973-03-02
Abstract: 1392785 Pyrolytic carbon coatings GULF OIL CORP 2 March 1973 [9 March 1972] 10301/73 Heading C1A [Also in Division C7] Pyrolytic carbon, optionally together with a carbide, is deposited on substrates in the presence of particles of size less than 1 mm., e.g. 50-600 Á, by flowing a C-containing gas or vapour over the substrate heated together with the particles in a fluidized bed coating enclosure, wherein particles which have grown in size are removed from the enclosure and smaller particles are introduced into the enclosure thereby maintaining the total deposition surface within the enclosure substantially constant, the particles being removed from the upper portion of the fluidized bed via a conduit up which flows a gas inert to the particles, to thereby control the removal rate. The substrate may be a mandrel or spheres of size 5 mm. and above of C or UC. The process may be carried out in a rotary drum or preferably a fluidized bed 11. The bed of particles is fluidized by an inert gas, e.g. N 2 , He or Ar, introduced via a tube 19 in the lower conically shaped portion of the inductively heated tube 14. Coated particles are removed from the upper <SP>1</SP>/ 3  of the bed through the tubes 47 and 49 up which an inert gas is blown to control the rate of removal. To compensate for the loss of particles, additional particles are introduced above the bed via line 26. The ratio of the total deposition surface area to the volume of the enclosure may be in the range 2 :1 to 20 : 1 to obtain isotropic carbon coatings. In coating mandrels supported above the bed or large spheres, the small particles may be ZrO 2 . The carbide may be Si, B, W, Ta, Nb, V, Mo, Al, Zr, Ti or Hf in amounts from 20-30 atom per cent of carbon plus carbide.

Title: Method for the explosive deformation of material and articles manufactured according to this method
Inventor: VERBRAAK CORNELIUS ANTONIUS
IPC: B21D26/08
Filed: 1962-03-19
Abstract: In a method for the explosive deformation of material having a cubically face centred lattice and a texture, the shock wave of the explosion is directed conformally to the <110> direction of the crystals.  In examples the materials used are, e.g., brass having 70% copper and 30% zinc or austenitic stainless steel containing 18% chrome and more than 8% nickel which are cold rolled to obtain reductions of 50%, or 50-70% and over 70% (brass only) followed by heat treatment to bring them into an anisotropic state having a texture of {110} <112> prior to the explosive deformation which does not produce mechanical twins in the material. An iron-nickel alloy containing over 30% nickel, reduced by rolling from 50-80% and heat treated at 600-900  DEG C. for 15-30 minutes to obtain a texture of {358} <523> may also be used.  Alternatively the required texture may be obtained by forging to obtain a reduction in excess of 50%.  Sheet material may be continuously cast and subsequently forged.  After being cold reduced 50-70% the brass is heat treated at 200  DEG C. for 15-30 minutes and after a reduction in excess of 70% is heated at 900  DEG C. to produce secondary recrystallization. The stainless steel is heated to 400-600  DEG C. after the 50-70% cold reduction.

Title: Improvements relating to data storage arrangements, especially for digital computers
Inventor: FROGGATT ROBERT JUSTIN
Filed: 1956-04-07
Abstract: 863,634. Electric digital-data-storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 27, 1957 [April 7, 1956], No. 10673/56. Class 106 (1). A data-storage arrangement comprises a circulating store with an input and output path including a normally closed gate, a control signal generator and means for opening the gate at a predetermined time in response to a control signal from the generator to allow the recording in or reproduction from the store of an information signal, the generator being responsive to each opening of the gate to alter the timing of succeeding control signals. The invention may be applied to a magnetic drum storage system operating as described in Specification 863,635. This includes a constant-speed drum 1 which can accommodate sixty-four, six-binary-coded decimal-digit words on each circumferential track. As described in the above-mentioned Specification as each new word is stored, all the existing words are shifted in a clockwise direction to make room for it. An output pulse Pe from a cycle counter 15, 16 occurs when the first digit of the stored information is passing under the reading-head 9. Output signals from the reading-head passing via a gate 40, are normally prevented by an " inhibit print " potential on line 33, but when this potential is removed the next Pe pulse sets a trigger circuit 35 via gate 30 and the latter allows the same Pe pulse through a gate 36. This opens a gate 37 to allow a clock pulse Co to set a trigger circuit 39 which, in turn, opens a gate 40, allowing digit signals from the reading head 9 to pass through on line 32 to a printer or other output means. The output signal from the gate 36 is also fed back via a delay element 41 to inhibit a gate 42 and so prevent the next clock pulse Co from reaching the counter 15, 16. Accordingly, the next output pulse Pe from the counter will occur one digit time later and, during the next cycle, the second digit will be passed through the gate 40 to the printer and so on. When the last word has been read out the pulse Pe occurs during the period of a pulse Wo initiated by a datum signal on the drum. This inhibits the gate 30 and passes a signal through a gate 31 which has the same effect as the " inhibit print " potential. It is stated that the system could be adapted for entering data into the drum store, in which case the system described in Specification 863,635 could be adapted for reading out. Specifications 707,634 and 827,582 also are referred to.

Title: Device for recording the incidence of radiation due to an atomic explosion
Inventor: PAVRY FRANCIS HILARY
IPC: G01S11/12
Filed: 1953-04-20
Abstract: 732,737. Recording radiation from an atomic explosion. MINISTER OF SUPPLY. April 20, 1954 [April 20, 1953], No. 10727/53. Classes 98 (1) and 98 (2). The apparatus enables an atomic explosion to be located by recording the direction of incidence of radiation therefrom, and comprises a container with means for orienting it on a given compass bearing, and a screen assembly, also oriented, mounted in the container and having radiation sensitive screen portions, with a scale thereon or associated therewith, the radiation-responsive screen portions being arranged to be partly shielded within the container in such a manner that upon at least one of the screen portions there is obtained with reference to the associated scale or scales a compass indication of the radiation received from any direction around the container and incident thereto within a given range of angle to the horizontal, and where the incident radiation is horizontal it is caused to strike a sensitive screen portion normally. As shown, the inner assembly of the device comprises four part-cylindrical recording screens 3, 4, 5, 6 of low heat conductivity mounted on a metal disc 10 with a sleeve 12 by which it may be mounted on a vertical rod 15 and clamped by a set-screw 14. A hollow cylindrical casing 1, with a domed top 7, fits over the inner assembly and is located by guides 9 on the casing engaging prolongations 8 of the adjoining edges of the screens. One of the guides 9 is shortened and the corresponding edge 8 is cut away, so that the casing can only be put on in one position. Holes 3a, 4a, 5a, 6a are formed near the top of the casing opposite the centres of screens 3, 4, 5, 6 respectively. Each screen carries a scale chart marked in bearings, the top 7 of the casing carrying a mark whereby the device and the scales are oriented. When an explosion occurs, the heat radiated therefrom falls on one or more of the charts, the screens being treated with heat-sensitive paint so that the bearing of the explosion is recorded. The charts may also have horizontal lines so that the angle of elevation of an air-burst may also be determined. The screens may be covered with photographic paper instead of heat-sensitive paint. Lenses may be fitted into holes 3a, 4a, 5a, 6a.

Abstract: 1501835 Wiped - wall reactor ALLIED CHEMICAL CORP 17 March 1976 [6 May 1975] 10742/76 Heading B1X A horizontal cylindrical wiped-wall polymer reactor adapted to have, in use, substantially horizontal polymer flow with a pool of polymer in its lower portion comprises driven wheels for creating high polymer surface area to facilitate evaporation of volatiles from the polymer in use of the apparatus, a drag wheel driven by the driven wheels although having a limited freedom for rotation relative to the driven wheels, and a wiping means mounted on the driven wheels and actuated by the drag wheel so as to wipe the entire internal circumference of said cylindrical reactor, the arrangement being such that, in use, the drag wheel urges the wiping means against the internal circumference of the reactor with a force generated by the drag of the pool of polymer on the drag wheel. As shown, driven wheels 5 are fixedly mounted on and driven by shaft 8, and drive wiper plate 1. Drag wheel 3 is free to rotate on shaft 8 but is driven from wheels 5 by an arm of the wiper plate which contacts pins in the drag wheel (Fig. 2 not shown). The drag wheel is provided with drag means 4; the force of the drag is transmitted by the pins-and-arm arrangement, causing the wiper plate to pivot about pin 2 so as to bear against and wipe, the internal surface of the reactor.

Abstract: 472,420. Directive wireless signalling. JOHNSKE, F. April 14, 1936, No. 10775. Convention date, April 10, 1935. [Class 40 (v)] In a directive system of the kind described in Specification 472,419, the electron-stream of the cathode-ray indicator is deflected first from right to left, and then from left to right, as the frame aerial makes one complete revolution, by means of a ring F, Fig. 1, which replaces the ring F in Fig. 10 of that Specification, but in which the timing sectors S are shaped as shown. They divide the ring into two differently-shaded parts so as to produce a curve with two minimum " dips " as shown in Fig. 2. This serves to indicate whether a position of symmetry is being maintained, the difference in brightness indicating the sense, and the distance apart the degree, of deviation. The signals may also be arranged to produce a sudden displacement of the electron stream, by introducing a rapid phase-change in the current applied to the deflecting electrodes at the " minimum " point, so as to produce curves of the form shown in Figs. 4 and 6. In Fig. 7 the ring F carrying the timing sectors S is provided with a concentric part II marked with radial lines which interrupt the light-beam falling on the photo-electric cell. The resulting impulses are used to supervise the scanning light-beam, used in Fig. 10 of the previously-mentioned Specification, and to give a warning signal should it depart from a given width. For landing an aeroplane in fog &c., the ring is used to superpose timing impulses upon the vertical radiation-field of a rotating frame aerial. These produce on the fluorescent screen of a cathoderay receiver carried by the aeroplane a minimum " dip, " which remains over the middle of the time axis so long as the aeroplane is flying along the correct downward path.

Title: Improvements in and relating to a method of building houses of artificial stone blocks
IPC: E04B1/04
Filed: 1937-04-15
Abstract: 494,008. Walls; blocks. BOMGREN, A. F. April 15, 1937, No. 10787. [Classes 20 (iv) and 87 (i)] A method of building walls from storey-high blocks 10, 15, which are of parallelepiped shape and are cast from porous concrete or other mouldable material having a low specific-weight and low heat-conductivity, consists in erecting the blocks on a base, such as a foundation wall or lower storey, in such a manner that thin through going and open joints are provided between adjacent blocks, and between the blocks and the base, steadying the blocks in an adjusted position in which plane outer and inner wall surfaces are formed, whilst maintaining free play between the opposing surfaces at the joints, and finally uniting the blocks with each other and the base by means of a binding mass which fills the joints. The joint spaces are provided by means of spacers 12 which are preferably of fibrous material and may be secured to the blocks during casting of the blocks, or by nailing or otherwise securing them to the cast blocks. The spacers 12 are placed on the edges of the blocks intermediate the faces of thereof. To form door and window openings, suitably-shaped blocks 10, 13, 14 are provided as shown in Fig. 1. The upper inner edges of the blocks 10, 12 are recessed to receive a flat iron plate 17 which, as shown in Fig. 9, is screwed to the blocks for the purpose of stiffening the structure and supporting floor beams 23 adapted to be bolted to the plate 17. For partition walls, the plate 17 extends across the full width of the wall and is bolted to the corresponding plate 17 of the outer walls. Adjacent blocks are secured together at the base by iron cramps driven into the blocks. After the blocks have been secured together in adjusted position, the joint spaces are sealed on the inner and outer sides by means of narrow strips 42, which are arranged as shown in Fig. 9 and may be formed of cement positioned by a spatula or trowel so that entirely smooth wall surfaces are obtained. After setting of the sealing strips 42, the joints are filled from the top with cement which flows through the vertical and horizontal joints, except in so far as these joints are stopped off by filling members placed at intervals in the horizontal joints. If desired, the joint material may be introduced at the time of erection of the blocks, being of such a character that it will not solidify until the blocks have been adjusted to their correct positions. The blocks, which have plane and parallel side faces and plane edge surfaces at right-angles to the side surfaces, may be faced exteriorly with a plaster or other covering.
