IPC: B28B19/00
Filed: 1976-12-06
Abstract: 1521165 Spray coating channel section members B J WILCE 6 Dec 1976 [4 Dec 1975] 49841/76 Addition to 1489604 Heading B2E [Also in Division B5] Gunite (a dry mixture of cement and sand) is wet and sprayed from a cement gun onto the external (Fig. 1) or internal surface of a mould member 1 or other item to form a coating having a U- or V-shaped channel therein. The timber or steel mould 1 is sprayed in several passes to form a gunite layer which after hardening receives further layers. In Fig. 1 the mould 1 is removed to leave a smooth internal surface 7 on the gunite 5. If the mould is internally coated (Fig. 2, not reproduced), then the gunite receives a smooth external surface. The mould can be lined with, or partly or completely replaced by, tiles or brickwork that are embedded in the gunite (i.e. mould forms part of finished article). In one example, a pair of mould walls define a V-shaped channel which is lined with tiles and then coated with gunite. On mould removal, a tiled roof is defined. An arched reinforcing mesh can be embedded.

Title: A plotting device for continuous analysis of radar indications on board ship or elsewhere
Inventor: TENGWALL GORAN AXEL KRISTIAN F
IPC: G01S7/24
Filed: 1968-10-21
Abstract: 1,206,499. Recording-apparatus. G.A.K.F. TENGWALL. Oct.21, 1968 [Oct.20, 1967], No.49920/68. Heading G1J. On board a vessel, in apparatus for assisting the continuous analysis of radar or other indications related to the course of a target, the target's true (or relative-to-the-vessel) course is plotted on a transparent film 13 movable (a) relative to a device for registering the relative-to-the-vessel (or the true) course of the target (b) at a rate representative of the velocity of the vessel and (c) in the opposite sense to (or in the same sense as) that of the velocity. The registering device may comprise a frame 1 supporting a plate 2, on which the vessel's course is represented by the zero mark of a scale 4 graduated in degrees, a transparent, rotatable disc 6 with a similar scale 7 and, between the plate 2 and disc 6, a transparent disc 8 marked with diameters 9 bi-secting one another at right angles and a distance scale of concentric rings 10 whereby the target's polar co-ordinates relative to the vessel can be used to register the target's position on the disc 6. A frame 21 supporting the film and its drive mechanism is hinged to the frame 1 at 22 and a counterweight 23 facilitates raising and lowering the frame 21. The film 13 is fed over the surface of disc 6 from a spool 15 to a spool 16, through tensioning rolls 14 and a grooved roll 17, against which it is pressed by a rubber roll 18. A stepping motor 20 drives the spool 16 and, through gearing 19, the roll 17. The motor 20 is controlled by the vessel's log or by a simulator through an electronic circuit, Fig.4 (not shown), so as to drive the film 13 at a selected ratio of the speed of the vessel. Data related to the position of a target relative to the vessel is plotted on the film 13 intermittently by hand with the aid of the discs 6, 8. The true course of the vessel is indicated by the reading of the scale 7 set against the zero of the scale 4 by turning the disc 6 in the opposite direction to a change of course. A record of the target's course relative to the vessel is thus plotted for the duration of each course steered by the vessel. The registering device may comprise a relative plotting device situated movably above a radar image. Indirect lighting 30, a clock 31, and a time-speed diagram 3 are provided.

A pipe coupling includes a male part 8 and a female part 1, the latter having an end flange 2, a first internal groove 5, a second internal groove 4 and a section having two diametrically opposed widened portions 7. The male part 8 has two corresponding diametrically opposed widened portions 9. The parts are coupled by inserting the male part 8 within the female part 1 having the portions 7, 9 aligned so that the latter may enter the first internal groove 5. The male part 8 is then rotated about its longitudinal axis. Stops 10b, which are larger than stops 10a, prevent the anti-clockwise rotation of the male part 8, as viewed in Fig. 2, and when the said part is rotated clockwise the stops 10a act as a locking device to hold the parts of the pipe coupling together. Stops 10b also act as a limit on the extent of the clockwise rotation. A sealing ring 3 may be included in the second internal groove 4. The parts 1, 8 may be arranged in various ways when applied to the construction of a pipe system, for example like or unlike parts may be located at the ends of given pipe sections or two female parts 1 may be fitted back-to-back to act as a junction piece. The coupling is preferably made of plastics and the coupling parts may be formed separately and welded to the ends of existing pipe sections or plain piping may have its ends shaped to produce the required coupling part.

IPC: G01M3/28
Filed: 1966-11-14
Abstract: 1,211,199. Valves and valve testing. GAS COUNCIL. 7 Feb., 1968 [14 Nov., 1966], No. 50860/66. Heading F2V. [Also in Division F4] A method of testing whether two fuel valves 12 and 13 series connected in a fuel line 10 to a burner are effectively closed comprises subjecting the enclosure 15 between the valves to suction and confirming that the resulting pressure in the enclosure 15 is consistent with the values being closed. The method may be applied in three ways: firstly, the enclosure 15 is evacuated and a check made (by means of a pressure switch P) that a predetermined pressure is reached in a predetermined time; secondly, the pressure in enclosure 15 is reduced to a predetermined value and the enclosure 15 shut off from the suction source and the pressure checked that it does not rise above the value in a predetermined time; thirdly, the first and second ways are combined sequentially. The two valves may be combined in a single valve for example as an Figs. 8 and 10. In Fig. 10 a disc 40 can be moved in a chamber 41 towards and away from a port 42 open to an inlet passage 43. When closed the disc 40 seats on concentric O-rings 45, 46 between which there is a space 47 connected to the valve test means by a passage 48. In Fig. 10 a slide 64 is slidable between a slipper 65 and two concentric seals 66, 67, seated to a valve casing 60 as by O-rings 68, to interconnect inlet and outlet passages 62, 63 by way of a passage 69 in the slide 64 (shown open in Fig. 10).

Title: Process for reducing calcium sulphate scale formation
IPC: C02F5/08
Filed: 1972-11-08
Abstract: 1451608 Calcium sulphate crystals FISONS Ltd 16 Oct 1973 [8 Nov 1972] 51454/72 Heading C1A In a process in which crystals of calcium sulphate anhydrite and/or hemihydrate are washed with a circulating liquor containing an antiscaling additive to inhibit the formation of calcium sulphate scale, the said additive is incorporated into the liquor between the point at which it is separated from the crystals and the point at which it is collected for recirculation. Where washing is carried out on a vacuum filter the additive may be added before the liquid reaches the seal box, and where a rotating pass filter is used, the additive may be added to circulating wash liquor through ports in the central valve of the filter. The crystals may be those obtained in a process for producing phosphoric acid by the wet process wherein a slurry of calcium sulphate hemihydrate and/or anhydrite crystals in phosphoric acid is formed and the crystals are separated from the slurry and washed with a circulating liquor which contains the anti-scaling additive. Suitably the additive is incorporated only into liquors containing less than 30% by weight phosphoric acid, expressed as P 2 O 5 , and is used in a concentration of 0À0005 to 0À2% by weight based on the liquor to be treated. Thus the additive may be added to the liquors from the last two stages of a four-stage washing process, so as to provide from 0À005% to 0À1% by weight of the additive in each of the liquors. A wide variety of anti-scaling additives may be employed, including anionic surface-active agents, e.g. alkaryl sulphonic acids and their salts, mono- and di-alkyl sulphate esters, sulphate esters of alkylene oxide condensates with alcohols, glycols or alkylphenols, alkane sulphonates, and mixtures of these. Non-ionic surface active agents may also be used, e.g. condensates of ethylene, propylene or butylene oxides with an alcohol, glycol or alkylphenol or mixtures thereof. Mixtures of anionic and non-ionic surface active agents can be used, and certain flocculating agents, e.g. polyacrylamides, and condensed phosphates with M 2 O/P 2 O 5  molar ratios of less than 2 : 1, as, e.g. sodium pyrophosphate, metaphosphate and tripolyphosphate.

Abstract: 1,162,140. PNPN switches. JOSEPH LUCAS (INDUSTRIES) Ltd. 8 Nov., 1966 [6 Dec., 1965], No. 51618/65. Heading H1K. In a PNPN switch in which the surface of the P-type gate layer is divided into two parts by the cathode layer the gate contact is disposed on one part while a layer containing diffused recombination centres extends across the junction between the other part and the cathode layer. A typical thyristor of this type is made by lapping and etching a 40 ohm cm. N-type silicon wafer to a thickness of 10 mils, placing it in vacuo at 1250‹ C. for an hour with a source of aluminium vapour and maintaining the heating in air for 4 hours after removing the aluminium source. After cooling the wafer is heated in a flow of phosphorus pentoxide vapour to complete an NPNPN structure. After etching off one of the outer N layers the remaining outer N layer is reduced to the required shape 16 (Fig. 8) by photo-resist etching. The wafer is then heated in boron to increase the surface doping of the P region, cleaned, and plated or vapour coated with nickel. This is diffused in by heating at 800‹ C. for a few minutes in a nitrogen/ hydrogen atmosphere. After replating with nickel the exposed gate-cathode junctions are masked and the exposed nickel plated with gold. After removing the mask the wafer is etched in ferric chloride to remove the nickel short-circuiting these junctions and the nickel diffused layer bridging the junction between one exposed part 120 of the gate layer and the cathode.

In a molten sodium cooled fast reactor, the core and heat exchangers are mounted within a pressure vessel. In order to interrupt the flow of coolant through one or more of the exchangers without interrupting the circulation through the remainder, an inert gas is injected into the upper volume of the selected exchangers. The gas forms a coolant free surface within the exchanger and acts against the pump pressure to prevent the coolant inflow to the exchanger. The core 8 is cooled by sodium circulated by pump 42 through the exchanger 24. The sodium enters 24 through the inlets 28 and flows downwards to the outlets 30 and to arrest coolant flow, argon gas is injected into the bell casing 46 through the pipe 48. A free sodium surface is established in 26, Fig. 3, and coolant entry through the inlets 28 ceases. Convection cooling occurs when the pumps are not operating.
