Abstract: 781,354. Storing liquefied gases. CONSTOCK LIQUID METHANE CORPORATION. Sept. 16, 1955 [March 16, 1955], No. 26580/55. Classes 8(2) and 102(2). [Also in Group XXXIII] A plurality of separate liquefied gas, e.g. methane storage tanks 5 are held in nested relation within a metal container by a heat insulation lining 4 thereof, e.g., of balsa wood. The container comprises a double-walled hull of a ship (see Group XXXIII] and each tank 5 which is of aluminium or austenitic steel capable of resisting fatigue at low temperatures is connected by a downpipe 7 to an insulated manifold 6 and by a short pipe 8 to a gas discharge manifold 9 which has a branch 10 opening to the interior pores of the balsa wood lining 4. The thickness of the latter is such that any liquefied methane coming into contact therewith is vaporized before reaching the inner wall 3 of the hull. Methane may be discharged as vapour through manifold 9 and valve 3 by passing warm air or liquid between the hull walls 1, 3 or the vapour may serve to force liquid methane up the pipes 7 and along a manifold 6 and through a pipe 12 coupled thereto and discharging into a storage vessel 10a. Air which may have entered the tanks, e.g. during filling thereof, is expelled by carbon dioxide vaporized from a solid block of carbon dioxide at the bottom of each tank.

Abstract: 1,050,850. Water-tube steam boilers. H. VORKAUF. Nov. 4, 1964 [Nov. 11, 1963; Aug. 5, 1964], No. 44994/64. Heading F4A. In a water-tube steam boiler a frame of tubes is built up of individual tube elements each arranged in a vertical plane and in close contact with adjacent elements to form the walls and flue of the boiler. In the arrangement shown in Fig. 1 the tube elements are formed by two " L "-shaped tubes 1 and 11 welded together with inlet and outlet connections 2 diagonally opposed and joined to a distributer 4 and header 5. A further tube 6 of the same diameter as the " L "-shaped tubes joins the top and bottom arms of the element so that in conjunction with adjacent tube elements a partition wall defining an internal flue is formed. Tubes 7 of a smaller diameter than the " L "-shaped tubes are provided in some of the tube elements to form in conjunction with other elements a heating surface in the flue. The front and rear walls of the boiler consist of end tubular elements 1, 1<SP>1</SP> in which vertical tubes 10 are inserted close up against one another with a burner 11 positioned in the front wall. A steam separating drum 3 is connected to the distributer by tube 15 and to the header by tubes 12 and 13, and unheated return tubes 14 connect the header to the distributer. These tubes 12, 13, 14, and 15 together form a framework that supports the arrangement of tube elements. In a modification the tubular elements are formed by one tube bent into a " U "-shape with another tube joining the free arms, and with this arrangement the header and distributer are connected to the free arms of the " U " tube. To overcome circulation problems caused by certain outer wall tubes that are only partially heated inserts extending axially within the tube elements near the outlet connection are used to separate the flow in the tube.

Partially hydrolysed polyvinyl esters of predetermined degree of hydrolysis by alkaline saponification of polyvinyl carboxylic acid esters in liquid media, are prepared by a process which comprises treating the polyvinyl ester in the presence of water with a material providing alkali metal ions after predetermining the ratio between the alkali metal and the water to predetermine the degree of hydrolysis of the polyvinyl ester, and allowing the saponification to continue until it ceases spontaneously. The polyvinyl ester may be polyvinyl acetate, the liquid medium may be methanol and the sodium ions may be provided by sodium methylate. The treatment may be effected at elevated temperature, and the degree of hydrolysis may be determined during treatment by testing samples by colorimetric analysis, e.g. using iodine and boric acid. After saponification has ceased spontaneously the degree of hydrolysis may be fixed for the recovery stage by adding water or aqueous acetic acid.

Abstract: 1,225,156. Hydraulic brakes. WAGNER ELECTRIC CORP. 20 March, 1968 [28 March, 1967], No.13399/68. Headings F2E and F2F. In an hydraulic braking system having a tandem master cylinder 2 connecting the front and rear brake branches 4 and 3 respectively, a control valve 19 is provided in the circuits 15 and 16 leading to the front and rear brakes 18, 24 respectively, the control valve including a warning device to indicate one of the circuits is malfunctioning. A proportioning valve 21 is provided in conjunction with the valve 19 to modify the pressure supplied to the rear wheel brake cylinder 23. The valve 19 comprises a piston or switch actuating member 47 slidably received in the bore 26 of the valve housing and having opposed ends 48, 49 for abutting engagement with spring retainers 45, 43, such that hydraulic pressure is normally supplied in an uninterrupted manner via conduit 16 to the wheel brake cylinder 17 of the front brake and via conduit 20, flow ports 34, 35, via the proportioning valve, conduit 22, flow ports 38, 39 to the rear wheel brake cylinder 23. The piston 47 under these circumstances is kept in its central position shown in Fig. 2 so that the electrical switch 58 is not actuated due to the contact 6 3 being kept off its seat 64 by the land 54 of the piston 47. In the event of failure of the line 16 leading to the front wheel brakes, the piston 47 will be urged to the left to actuate the switch 58 and illuminate a driver's warning lamp 69 and, at the same time fluid will flow via a by-pass passage 55a of the piston through a seal 40 to connect the chamber 28 in by-pass relationship with the housing recess 37 and delivery port 39 into the wheel brake cylinder 23 to energize the rear brakes 24 without the proportioning valve 21 coming into effect. In the event of the failure of the rear wheel braking circuit the piston 47 will be moved to the right to actuate the electrical switch 58 to warn the driver of the failure of the rear wheel braking system. In a modified circuit (Fig. 4, not shown) the proportioning valve 21 is provided in a circuit between the flow ports 34 and 39, the flow ports 38 and 35 being blanked off. In a modified construction of the valve, shown in Fig. 5, the piston 205 is formed with a V-shaped groove 210 to which is urged a follower end 219 of a modified switch member 214 so that movement of the piston 205 to the left or to the right will move the follower end 219 upwardly against the action of a spring 221 to make contact with the terminal 216 and complete the circuit to illuminate the driver's warning light 69.

Abstract: 1,225,236. Vitrified ceramics; enamelling. TAYLOR, TUNNICLIFF & CO. Ltd. 3 July, 1968 [4 April, 1967], No. 15360/67. Headings C1J and C1M. Ceramic bodies having a dense vitrified structure and less than 4% closed pore volume are produced by firing a ceramic composition in the form of a pre-shaped coherent mass containing clay and including fusible and/or glassforming components in the presence of hydrogen at the peak firing temperature. The invention is applicable to steatite, cordierite, alumina-enriched porcelain, zircon porcelain or electric insulator porcelain bodies, which may be shaped by conventional plastic moulding and initially prefired in air below vitrification temperature, or in air followed by nitrogen, before the firing in hydrogen. For example, firing in air up to 1100‹ C. may precede firing in hydrogen to 1200‹ C., cooling, and then re-firing to 1250‹ C. The invention also applies to glazing porcelain or other ceramic bodies, the unfired body being coated with a ceramic glazing composition and the coated body vitrified and matured in a hydrogen atmosphere.

Abstract: 1,231,592. Photographic dye-developer transfer process. EASTMAN KODAK CO. Aug.29, 1968 [Aug.30, 1967] , No.41241/68 Heading G2C. A colour image is produced by the photographic dye-developer diffusion transfer process in which a photographic material comprising a support and at least one light-sensitive silver halide emulsion layer which contains a dyedeveloper or is contiguous to a layer containing a dye-developer, which has been exposed to a light image, is processed by allowing an alkaline aqueous liquid, that causes the dye-developer to develop the latent image, to permeate said layers and by allowing the residual unoxidized portions of the dye-developer to transfer imagewise by diffusion and in register to a receiving layer contained in a receiving material and in which the receiving material containing the colour image is separated from the processed photographic material, characterized in that the alkaline liquid contains from 0À5 to 3% by weight of hydroxyelthyl cellulose and in that there is introduced into the alkaline liquid between the photographic material and the receiving material before said separation a water-soluble amphoteric salt of zinc, antimony or lead. This salt may be (i) in the alkaline liquid before said permeation, (ii) it may be distributed in the receiving material from which it is dissolved in the alkaline liquid during processing, or (iii) it may be in both situations. In situation (i) the concentration of the salt is preferably 0À05 to 0À9% by weight of the alkaline solution; in (ii) it is preferably 0À005 to 0À2g. per square foot of the receiving layer. Suitable amphoteric, soluble metal salts include zinc acetate, zinc nitrate, potassium antimonytartrate, lead acetate and lead nitrate. By means of this invention a viscous activator layer which may contain a relatively small amount of hydroxyethyl cellulose will cleanly and easily strip from a dye-developer reception layer even when a relatively short processing time is used.

Abstract: 1,238,421. Colour television; automatic volume control. PYE Ltd. 29 April, 1969, No. 21732/69. Headings H4F and H4R. The gain of a transistor comprising the amplifier stage for a colour television signal including alternating chrominance and colour burst signals is controlled by a variable resistive device in the emitter circuit of the transistor which device provides negative feedback for the amplifier stage, the resistance of the device being controlled by a gain controlling signal derived from a control stage at the output of the amplifier stage, to which control stage the amplified colour burst signal is selectively applied. In the arrangement shown the variable resistive device is a diode D1 poled in the same direction as the base/emitter junction of the amplifier satge transistor T1 and having an I/V characteristic slope which changes slowly and uniformly throughout the operating range. Alternatively a resistance network may be used to provide the diode D1 with the desired characteristic. The gain controlling signals are applied to the diode D1 through the base of the transistor T1 together with the alternating chrominance and colour burst signals, selected via a high pass filter R1/C1. The amplified output from the transistor T1 is passed via a tuned circuit L1/C3, tuned to the colour sub-carrier frequency, and a transformer L1/L2 to an output terminal 5. Positive keying pulses are applied to a terminal 3 to coincide with the arrival of the amplified colour bursts at the secondary winding L2, and these pulses serve to switch off a diode D2 to prevent the amplified colour burst signal from passing on with the amplified chrominance signal to a decoder, and to cause a normally non- conducting transistor T2 to conduct so that the amplified colour bursts are applied to the burst output terminal 6 and, via a further tuned circuit, to a third transistor T3 comprising the control stage. The output from the transistor T3 is coupled back, via a potential divider R10/ R2/R3, to the base of the amplifier stage transistor T1 to provide the gain control signal. A capacitor C8 holds the collector voltage of the transistor T3, and hence the gain control signal to the transistor T1, substantially constant during the periods when the chrominance signal is being passed, during which periods the absence of the keying pulses from the terminal 3 causes the transistor T2 to be switched off and allows the diode D2 to conduct. The starting point of the automatic gain control action may be adjusted by varying the value of a resistor R7 in the emitter circuit of the transistor T2.

Abstract: 1,258,632. Digital processors. HONEYWELL Inc. 13 Jan., 1969 [29 March, 1968], No. 1975/69. Heading G4A. For diagnostic purposes the parity bit of a word to be read in to the store of a processor can be inverted to distinguish the word. The circuitry described provides, under selectable conditions, stop or synchronizing signals on detection of inverted parity in a word read out. The store comprises a core matrix memory 10 from which a word is read via units 14, 30 to register 16 and check unit 31. The latter derives a parity bit which is compared at 32 with the parity bit in 34 from the word read out. Register 16 passes the word read out to the store 10 via units 15, 12. Unit 17 generates a parity bit for this word, the bit being passed to gate 37 in true or inverse form as selected by switch 46. If a comparator 32 shows a parity error, subsequent action depends on the position of switch 46. If switch arm 48 is as shown, gate 35 outputs during Read, if the arm is on C gate 50 outputs during Write, and if the arm is on B gate 51 outputs during Read and Write. The output of these gates passes either via gate 61 or gate 62, dependent on switch 60, to provide a pulse which stops operation so that the point in the program at which the stop occurs can be assessed, or to provide a sync. pulse to a c.r.t. which displays the electrical conditions occurring in a memory loop set up after faulty operation has been detected to produce the fault signal repeatedly.

Abstract: 1,259,483. Measuring weight electrically. YAWATA IRON & STEEL CO. Ltd. and MITSUBISHI SEIKO K. K. Feb.18, 1969, No.8740/69. Heading G1N. A small variation from a given load is determined by balancing substantially all the load, and connecting a load cell in alignment with the balancing device to completely balance the load, any variation in load then acting substantially totally on the load cell. As shown, the load W is suspended from a plate 20 and is balanced by a spring 23 which causes an electrical output to be obtained from a load cell 31. Compressed air is then applied to cylinders 36 and pistons 41 push friction pieces 33 mounted on leaf-springs 34 against friction pads 32. If the load decreases by a small amount, the spring 23 pushes member 21 and thus plate 27 upwardly thus compressing the load cell to give an indication of the decrease in load. The spring constant of the load cell is arranged to be much larger than that of the spring 23 such that nearly all the load is the magnitude of the decrease in load, is applied to the load cell and is always a constant percentage. In alternatives, the load may be balanced on a lever-fulcrum arrangement, the load cell may be mounted in tension rather than compression, the load cell may be a differential transformer, and the load may be balanced by a weight rather than a spring.
