Title: Improvements relating to hydraulic seals of carburetted water gas and other apparatus
IPC: C10J3/72
Filed: 1930-02-25
Abstract: 347,375. Hydraulic seals for water gas apparatus. HUMPHREYS & GLASGOW, Ltd. and BARRATT, W. A., Humglas House, Carlisle Place, London. Feb. 25, 1930, No. 6242. [Classes 55 (i) and 55 (ii).] In water gas apparatus a hydraulic seal which during various phases of operation is automatically adjusted to the requirements of the moment, comprises a wash box divided into compartments 1, 2 connected at their base, a gas inlet pipe 5 dipping into chamber 2, a gas outlet pipe 6 connected to the same chamber and a water overflow pipe 8 connected to chamber 1 the latter being also in communication with outlet and inlet mains by pipes 9, 10. The junction of the latter pipes is fitted with a three-way cock 12 operated from the generator blast valve gear so that chamber 1 is connected with main 11 when the stack valve is open and with the gas inlet 5 when the blast valve is open. This results in a seal depth which is increased during the "blow," reduced during the "run" and normal when the plant is standing. In a modification, a supplementary three-way cock 12a, Fig. 4a, operated by the stack valve gear is inserted in a loop connection between the pipes 9, 10. During the blast purge after the "run," the overflow chamber communicates with the gas main through the cock 12a, the connection to the gas inlet being closed. This obviates increase of seal depth during the blast purge.

Abstract: 939,802. Seaming non-metallic sheet material. J. LYONS & CO. Ltd. Feb. 24, 1960 [Feb. 24, 1959], No. 6315/59. Class 42 (1). A method of sealing or joining thin sheet thermoplastic material of low power factor, i.e. a power factor insufficiently high to cause sufficient heating by radio frequency energy for sealing or joining, under initial conditions of normal temperature and pressure, by the application of radio frequency energy, comprises bringing into contact with the surface of the sheet material a material of higher power factor and subjecting both materials to said energy. The method is particularly applicable to seaming polyethylene terephthalate film and polyvinyl chloride is used as the material having a higher power factor.
Patent GB-402730-A (GB)
Title: Manufacture of cellulose esters
IPC: C08B3/08
Filed: 1932-03-02
Abstract: Cellulose is esterified with a reaction mixture containing butyric acid a propionic acid, and/or lower fatty acid anhydride. For example, when propionic acid is used, one of the following anhydrides could be employed, viz., acetic anhydride, chloracetic anhydride, methoxy-or ethoxy-acetic anhydride, and when butyric acid is used, propionic anhydride, chlorpropionic anhydride, alkoxy-propionic anhydride, acetic anhydride or its derivatives may be present.  The esterification-impelling anhydride may or may not itself also contribute acyl groups to the product.  In this way mixed esters, e.g., cellulose propionate-butyrate, cellulose acetate-propionate, cellulose acetate-butyrate, and cellulose acetate-propionate-butyrate may be obtained.  The following Examples are given:--(1) Cotton is esterified in a bath comprising propionic acid, acetic acid, acetic anhydride, and zinc chloride, to produce a mixed acetate-propionate. (2) Cotton is treated with a mixture comprising butyric acid, acetic anhydride, acetic acid, and magnesium perchlorate trihydrate.  (3) Cotton is esterified in a mixture comprising propionic acid, acetic acid, acetic anhydride, and sulphuric acid.  (4) Cotton is esterified in a bath comprising propionic acid, acetic anhydride, ethylene dichloride, and sulphuric acid.  (5) Cotton fibres are acylated so as to retain their fibrous structure by pretreating with propionic acid and perchloric acid, and reacting with a mixture of carbon tetrachloride and acetic anhydride.  The products may be utilized in the production of filaments, films, lacquers, and the like.

Title: Improvements in or relating to devices for guiding the sides of metal strip
IPC: B21B39/14
Filed: 1962-02-19
Abstract: 978,773. Rolling. VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A.G. Feb. 19, 1962 [Feb. 22, 1961], No. 6364/62. Heading B3M. A device for guiding the sides of a metal strip to a rolling or like mill comprises opposed guide bars movable transversely of the strip and carrying rollers, and is characterized in that a drive means for one of the bars includes a spring of variable initial stress which, when overcome by the compression force of the guides on the strip, causes the said driving means to be stopped. The two guide bars 2, 3 carry rollers 4 and are provided with transverse slideways on a table 1 which can be raised and lowered. A lug 7 is mounted on a fixed frame member 8 and carries an hydraulic cylinder 6a; the piston rod of this hydraulic unit is coupled to the slide 3. A second hydraulic cylinder 5a mounted on a member 11 is carried on a hollow screw-threaded shaft 12 having an internal abutment for a spring 9 housed in a bore in the fixed member 8. The required chip compression is set by prestressing spring 9 with screw 12. In operation, hydraulic pressure is supplied to the cylinders whose pistons pull the guide on the opposite side of the machine towards them until they have both contacted the sides of the strip to be guided. When the compression of the strip thus induced exceeds to pre-set compression in the spring 9, the cylinder 5a will move to the right. This movement actuates a limit switch, not shown, which cuts off the hydraulic supply to the two cylinders. The guide traversing may alternatively be derived from electric motor-driven screw spindles or other mechanical means.

Abstract: 948,990. Voltage regulation. COMMUNICATIONS PATENTS Ltd. Feb. 21,1962, No.6656/62. Heading G3X. A voltage regulator for supplying current to a load 17 comprises a discharge tube 10, having its anode connected over a resistor 11 to a positive potential 13 and its cathode connected in series with a resistor 18 to a negative potential 19, and a rectifier 15 connected as shown in series with the tube 10 to a point of potential 16 intermediate the potentials of 13 and 19. In operation, at the instant switch 12 is closed the tube is connected across 13 and 19, and the initial voltage V1 + V2 causes the tube discharge current to flow whereby rectifier 15 becomes conductive; the circuit then acts as conventional voltage regulator in which the cathode of tube 10 is connected directly to terminal 16, i.e. the voltage V2 acts only as a priming voltage which is added to voltage V1 to initiate the discharge. A number of discharge tubes connected in parallel may replace the tube 10, or a number may be connected in series with the rectifier (Fig. 2, not shown).
