Patent GB-1362920-A (GB)
Title: Butterfly valves
IPC: C10L1/14
Filed: 1972-11-16
Abstract: 1362920 Valves JAMESBURY CORP 16 Nov 1972 [9 Dec 1971] 52951/72 Heading F2V A butterfly valve for use with hot slurries comprises an annular metal seat 40 formed with a lip 50 which is pre-loaded by its own resiliency against the closure disc 20, there being a gap between a surface 54 of the seat and a surface 66 of a retaining lug whereby flexure of the lip is facilitated. The lip provides a seal for slurry flowing from the right under pressures of up to 100 p.s.i. However, for slurry flowing from the left, a seal is provided for pressures of up to 500 p.s.i. owing to the additional loading of the lip by the slurry. In the open position of the valve the closure disc 20 is completely out of contact with the seat. A retaining ring 30 for the seat is shaped to mitigate the abrasive effect of the slurry as it flows through the seat. The valve can be made entirely of stainless steel. High lubricity and hardness is imparted to the seat by an organo-metallic fusion coating process. The bearings of the valve include glass fibrefilled PTFE.

Filed: 1969-10-30
Abstract: 1283728 Measuring frequencies GENERAL RADIO CO 30 Oct 1969 53275/69 Headings G4A and G4H In determining the frequency of a signal from a source 3 in terms of pulses from a clock 1, the measurement period is determined by a programme controlled by registers 7, 5 receiving the pulses from 3, 1, respectively. After the measurement is completed the frequency is computed and indicated at 23. A monitor 9 continuously compares the two most significant decimal digits from clock register 5 and the lowest decimal digit from signal register 7. If the former exceeds 48 while the latter is 0 or 1 then control circuit 11 stops the measurement at the next signal from 3. Similarly for valves 78 and 2-7, or if the register exceeds 8 when the highest digit in 5 is 9. An arithmetic unit 20 then divides the valve in 7 by that in 5 by repeated subtraction with decimal shift to give the answer in register 26 and indicators 23.

Title: Prevention of coking in pyrolysis plants

Abstract: 1,267,467. Preventing coking in pyrolysis plants. DEUTSCHE TEXACO A.G. 10 Nov., 1970 [28 Nov., 1969], No. 53450/70. Heading C5E. Coke obstructions are prevented in pyrolysis plants by causing the coke to deposit on a sieve in an easily accessible position in the flow path of the cracked gas stream between the pyrolysis furnace and the cooler. The sieve may comprise one or more wire mesh cages, preferably two disposed one within the other, the inner having a larger mesh size than the outer. In the example the cracked gases contain about 33 mole per cent ethylene obtained by pyrolysis of ethane. When the resistance of the sieve to the gas flow increases due to coke deposition the sieve is replaced.

Abstract: 1283533 Photo-sensitive lead oxide print-out material AGFA GAVAERT 4 Nov 1969 [12 Nov 1968] 53670/68 Heading G2C A print-out image is obtained by imagewise exposing a recording layer of a binding agent containing at least 25% by weight of yellow lead (II) oxide dispersed therein, to actinic radiation to such a degree that a print-out image is obtained. The recording layer may also contain red lead (II) oxide. The binding agent is preferably hydrophilic but, may comprise a mixture of hydrophilic and organophilic binding agents. The binding agent may be e.g. gelatin, casein, polyvinyl alcohol, copoly (vinyl-n-butyral/vinyl alcohol) containing at least 5 mole % of vinyl alcohol groups, carboxymethylcellulose, sodium alginate, poly (vinylamine), poly (ethylene oxide) or copoly (acrylic acid/acrylamide/ sodium acrylate). The yellow lead (II) oxide may be doped with a metal other than lead e. g. bismuth, molybdenum, lanthanum, copper or silver. The recording layer may contain an organic polyfunctional sensitizer of which at least two chemical functional groups are OH and/or mercapto and/or primary or secondary amino groups. Numerous examples of chemical sensitizers are given. The recording material may be exposed in dry or wet state, e. g. after dipping it in an aqueous solution containing a chemical sensitizer. The recording material may contain a wetting agent e. g. glycerol or water-attracting salts and hydratable metal oxides e. g. lithium chloride and zinc oxide. The sensitivity is increased by heating the chemically sensitized material e.g. between 60 and 150C. during imagewise exposure. The print-out image may be stabilized with an aqueous solution containing chloride ions or a water-soluble carboxylic acid e. g. an aqueous solution of polyethylene oxide (average molecular weight 4000), acetic acid and sodium chloride (Ex1).

Title: Dye jet printing
IPC: D06B1/02
Filed: 1974-12-12
Abstract: The inventors have declined to be named. The pattern-spraying printing apparatus has a plurality of ink-spraying nozzles. The ink jets issuing from these nozzles are periodically deflected, according to the pattern program, from the article to be printed, by air jets controlled by electromagnetic valves (92). The valves (92) are mounted in series on a carrier plate (106). A plurality of these carrier plates are arranged in succession. In order to avoid mutual electromagnetic disturbance effects, straight lines connecting analogue points of two directly adjacent valves (92) of two adjacent valve series (112, 114) form a respective angle alpha with the vertical magnetic axes of the valves which is between 35 DEG  and 55 DEG . A multiple electrical plug (118), a distributor (142) for the entering air, a multiple connection element (144) for the issuing air, the airlines between the distributor and the valves and between the valves and the multiple connection element (144) and the electrical lines are likewise mounted on the carrier plate (106). <IMAGE>

Patent GB-1594839-A (GB)
Title: Installation for packing radioactive waste material in drums
IPC: B30B9/32
Filed: 1977-12-29
Abstract: The system consists of a compression press operating partly in an alpha-particle-tight compression box (3) and is intended for carrying out all the operations required for compression in a single compact system. The press contains at least two tie rods (23) to the upper ends of which there is attached a compression cylinder (25) having a plunger (55) acting downwards, and between the lower ends of which there is attached thereto a compression table (24) which receives the waste drum (22), it being possible for the plunger (55) to be moved into the drum (22). The drum (22) can be raised with the compression table (24) by means of lifting devices, and can be pressed against the loading openings (32) in the floor (21) of the compression box (3). Provided between the tie rods (23) is a hollow injection cylinder (17) which can be moved into the drum (22) into whose interior (36) the plunger (55) can be moved. When the injection cylinder (17) is moved high, concrete is pressed into the annular space produced. The advantage of the system is that the waste is intimately connected to the concrete jacket and that the concrete jacket is produced simultaneously with the compression operation. <IMAGE>
