Title: Improvements relating to inert gas system for tank ships
Inventor: MACKENZIE ANGUS THOMAS
IPC: B65D90/44
Filed: 1961-10-26
Abstract: 982,791. Supplying inert gas to storage tanks &c. B.P. TANKER CO. Ltd., A. T. MACKENZIE, and E. TELFER. Oct. 10, 1962 [Oct. 26, 1961], No. 38353/61. Heading A5A. A system for supplying inert gas to storage tanks, e.g. in ships, comprises cooling means for inert gas (e.g. boiler flue gas, diesel exhaust gas or gas from a propane burner) and a fan for blowing the cooled gas into the tank, the maximum pressure which the fan can generate being equal to a predetermined value which is the pressure (usually slightly above atmospheric pressure) at which the tank is to be maintained. In the embodiment shown diagrammatically in Fig. 1, inert gas from a boiler uptake is drawn through a scrubber 1 and a filter 2 by the fan 3 driven by motor or turbine 4. The fan blows the inert gas into a main header 5 having side branches 6 carrying the gas to cargo tanks 7, each of which is fitted with a purging pipe 8 extending to the bottom of the tank and fitted with a valve (hinged cover with seal) 9, which enables gas to be blown through an empty tank to displace the air therein. Conversely, the fan may draw fresh air from the atmosphere through an inlet between valve 19 and scrubber 1 to replace inert gas with fresh air when desired. The main header 5 is vented to the air by vents 10, each of which is provided with a gate-valve 11 and a pressure and vacuum relief valve 12 connected in parallel, the former enabling tanks 7 to be vented during loading and the latter, being set to operate at + 2 and ¢ p.s.i.g., serving to release any pressure build-up due to volatilization of cargo. Inert gas is supplied to the main header 5 via a gate-valve 13 and non-return valve 14, and an oil-seal pressure and vacuum breaker 15 is provided as an additional safeguard. A pressure stat 16 is provided to start and stop the fan motor when the pressure reaches or falls to a predetermined figure (0.4 p.s.i.g. and 0.18 p.s.i.g. respectively), and an additional pressure stat 18 is set to give a warning if the pressure falls below 0.18 p.s.i.g. Specification 649,735 is referred to.

A liquid mixture such as milk or a solution of tea or coffee is concentrated and, if required, submitted to freeze drying, by injecting the liquid upwards through a vibrating nozzle 7 in a chamber 1 maintained under vacuum by pump 4, so that the injected liquid forms droplets which rise and then fall without contacting the walls of the chamber, the time taken to. rise and fall back being sufficient to allow liquid to evaporate adiabatically from the droplets thereby bringing about the required concentration and freezing. The vapours freeze on coil 3, which may be cooled with calcium chloride brine at -40C.; and non-condensable gases are withdrawn from the system by pump 4. The concentrated liquid or frozen particles are collected by chute 5 and directed onto plate 6 mounted above coil 10 which may be supplied with heating-medium if it is desired to effect freeze drying. Nozzle 7 may be fastened to a vibratory member arranged so that its natural frequency vibrations are maintained by electrical means. Chamber 1 may be provided with several nozzles.

Cellulose aceto-crotonates; preparatory treatment of cellulose. - Cellulose or a near transformation product thereof is treated with crotonic anhydride in the presence of acetic acid and of a catalyst, with or without a solvent and with or without a diluent. Mixed esters of varying composition are obtained; according to examples di-aceto mono-crotonates and esters containing less than 10 per cent of combined acetic acid are prepared. When the acetic content is low the esters resemble the pure crotonates, being for example soluble in benzene and benzene-alcohol mixture; the esters with a high acetic content are insoluble in these solvents but may be soluble in acetone. The products may also be soluble in chloroform, acetic acid, ethyl acetate, and toluene. They give strong transparent films. As raw material cotton, chemical wood pulp, which may have been purified, hydrocellulose, oxy cellulose, and hydracellulose are suitable. An advantageous preliminary treatment consists in impregnating the cellulose with acetic acid containing, if desired, a part or the whole of the catalyst; the quantity of acetic acid may be less than the weight of the cellulose. Sulphuric acid, aromatic or aliphatic sulphonic acids, such as methane-sulphonic acid, acid salts such as bisulphates, and also zinc chloride and perchlorates may be used as catalysts. Crotonic acid or benzene may be present in the esterification mixture. After the reaction, the mixed ester may be precipitated by water or alcohol. Specifications 22237/11, 287,880, and 289,853 (as open to inspection under Sect. 91 of the Acts) are referred to.

A number printing apparatus comprises a number-printing head 44, Fig. 1, a support 36 for the head, a first shaft 96, Fig. 3, for rotating the support 36, a second shaft 62 resiliently coupled to the first shaft, and an arm 60 on the shaft 62 engaging a number-advancing arm 56 on the head 44, means being provided whereby the second shaft 62 can be momentarily retarded so as to effect relative movement of the arms 56, 60 and thus advance the number on the head 44. Printing surfaces.-The number-printing head 44 has an extending part 48 fitting in a triangular groove of a support roller 36, and is secured by a set screw 50. Dating and endorsing stamps may also be carried by the roller 36. Number-printing apparatus.-The roller 36 is carried by a hollow shaft 96 driven continuously by a belt and pulley 98, 100. Inside the shaft 96 and connected thereto by a spring 102 is a shaft 62 which normally rotates with the shaft 96 and carries a grooved arm 60 engaging a pin 58 on an arm 56 attached to the shaft of the numbering wheels 52; one oscillation of the arm 56 causes the numbering wheels to be advanced one digit. At the end remote from the roller 36, the inner shaft 62 extends beyond the shaft 96 through a fixed electromagnet 90 and carries a brake plate 94. If the magnet 90 is energized, it attracts the plate 94 causing the shaft 62 to be stopped momentarily thus effecting an oscillation of the arm 56 and stepping up of the number. Energization of the magnet 90 can be effected by an operator if documents are to be numbered in batches, or, if consecutive numbering is required, through photo-electric devices 32, 34, Fig. 1, which sense the feeding by belts 24, 26 of the documents past the roller 36. The numbering head 44 may be advanced several digits for each revolution of the roller 36 by providing an impulse generator which supplies a predetermined number of pulses to magnet 90 upon generation of a pulse by the photo-electric device 32, 34 or the operator-controlled switch. Tripping.-An impression roller 38 carried by an arm 40 raised by an electromagnet when the devices 32, 34 sense the approach of a document, presses the document against the roller 36. Inking.-The numbering wheels are inked by a roller 20 contacting a roller 18 to which ink is supplied by a spray gun 10 carried by an oscillating shaft 12.

Abstract: 341,688. Lubricating valves. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Merco Nordstrom Valve Co. ; 343, Sansome Street, San Francisco, U.S.A.) Dec. 23, 1929, No. 39318. [Class 12 (ii).] In order to lubricate a plug valve automatically and independently of the line pressure controlled by it, the cylindrical valve member 12 of a plug valve is balanced with regard to line pressure and is rotatably and slidably supported in a bore 7 in the valve casing 10, so formed as to provide a chamber 9 at one end of the valve member which chamber is charged with lubricant under pressure from a compresser through a pipe 31 and a bore 30 in a head 20 screwed into the casing at 21. The end 22 of the head 20 is flattened and fits loosely into a correspondingly shaped bore 23 in the valve member and extends into a space 24 in the end of said member, which space communicates, by means of radial bores 32, with the chamber 9 through vertical grooves 34 in the valve member, and with the working faces of the valve through arcuate grooves 33, 35 at the upper and lower ends of the plug and vertical. grooves 36 in the casing. A second chamber 18 is provided at the other end of the valve member and is formed by a plug 11 screwed into a bore in the casing 10. Projections 38, 39 in the plug 11 and the valve plug 12 are in alignment and carry a spring 37 for forcing the valve member into the chamber 9. A bore 40 in the lower end of the valve member exhausts any leakage of lubricant in the chamber 18 through the valve bore 13 into the line 6. A rotary operating handle 25 connected to the head 20 effects the opening and closing of the valve. In operation, the chamber 9 is charged with lubricant under pressure until the projections 38, 39 abut against one another. Line pressure leaks past the valve faces to both chambers 9, 18 and balances the valve as regards this pressure. Operation of the valve dissipates lubricant between the valve and its seat and more lubricant is forced into the grooves 33, 35, 36 by the upward movement of the valve member under the influence of the spring 37. Specification 281,844 [Class 12 (ii), Lubricating passages &c.], is referred to.
