Title: Improvements in or relating to vessels for the transport of liquid cargoes by sea
IPC: B63B11/04
Filed: 1964-02-27
Abstract: 1,028,136. Flexible hull vessels for liquid cargoes. J. J. C. GARATE. Feb. 27, 1964, No. 8216/64. Headings B7A and B7S. A vessel for transporting liquid cargoes has that part of the hull carrying the cargo provided with an outer skin 3 (Fig. 1, not shown) having zero or very small buoyancy, the outside water being free to enter to direct inward pressure on a flexible membrane 5 accommodating the cargo for transport at a pressure at least equal to that of the outside water, the buoyancy of the vessel being concentrated in a small forecastle (Fig. 7, not shown) and a small quarter-deck, whereby the longitudinal bending moment and hence the necessary thickness of the structure of the vessel are reduced. The skin 3 is provided with holes for the flow of sea water and can have a light framing 4 providing buoyancy spaces to give the skin a displacement equal to its weight. The hull comprises sections 10 coupled at 11 to allow torsional deformation of the skin. The coupling is provided by a split tube 12 (Fig. 9, not shown).

Title: Physiologically active esters of vitamin d and a method of making same
IPC: C07C401/00
Filed: 1953-03-25
Abstract: The invention comprises a crystalline ester of Vitamin D3 and an aliphatic monocarboxylic acid having two to five carbon atoms in its molecule, e.g. n-butyric acid, propionic acid, isovaleric acid, said ester being antirachitically active, crystallizing in the form of colourless needles, melting at a temperature above room temperature, its ultra-violet absorption spectrum being lambda max: 265 mm , and the preparation thereof by adding an esterifying agent, e.g. a fatty acid chloride or anhydride, to a solution of Vitamin D3 in a tertiary amine, e.g. pyridine or dimethylaniline, reacting said mixture for a sufficient time to cause esterification of said Vitamin D3 and separating the resulting Vitamin D3 ester in crystalline form from the reaction mixture.  The reaction mixture may be prepared in a volatile organic solvent which is removed by evaporation in vacuo before the main reaction takes place.  The Vitamin D3 starting material may be resinous Vitamin D3 or crude Vitamin D3 which is obtained on irradiation of 7-dehydrocholesterol.  Alternatively an ester of dehydrocholesterol is exposed to ultra-violet light to obtain the desired ester.  Esterification is preferably carried out at room temperature or below.  The Vitamin D3 ester is purified by recrystallization from an organic solvent.

Title: Improvements in and relating to electric motor control systems
IPC: B60L15/20
Filed: 1928-03-21
Abstract: 309,290. Gray, W. T., Griffiths, S., and Associated Electrical Industries, Ltd. March 21, 1928. Handles; interlocking. - In electric motorcontrol gear for series-parallel control of railway motors, four operating-handles, each operating a separate switching device, respectively perform the four functions of acceleration by cutting out resistance, regenerative braking, series-parallel grouping, and reversing. Mechanical interlocks are provided between the four switches. As shown in Fig. 1, the four handles, viz. :- the accelerating handle 2, the series-parallel handle 9, the regenerative braking handle 11, and the reversing handle 17, are disposed on the topplate 1 of a casing which contains the four corresponding drum switches 21, 23, 22, 24, shown in Fig. 2. The accelerating drum 21 is connected by toothed gearing 37, Fig. 3, to the handle 2, the series-parallel drum 23 is linked through a connecting rod 34 to the handle 9, and similar mechanical means 38, 35 connect the respective drums 22, 24 to their handles 11, 17. The interlocks consist of cams, levers, and notched discs arranged to satisfy the following conditions. (1) The reversing drum is locked until the accelerating and series-parallel drums are in their " off " positions and the regenerative drum is in a motoring position. (2) The reversing drum, while in its neutral position, locks all the other drums. (3) The accelerating drum is locked " off " while the series-parallel drum is "off." (4) The series-parallel drum cannot be brought to the '' off position until the accelerating drum is " off." " (5) The accelerating drum has a full range of movement if the regenerative drum is in a motoring position. (6) The accelerating drum has a restricted range of movement (not extending to the field weakening notches) if the regenerative drum is in a braking position. (7) The regenerative drum cannot be changed from braking to motoring until the accelerating drum is "off." There is also a lock to prevent removal of the reversing handle from its spindle except in the neutral position. The invention is applicable to the control system described in Specification. 313,427.

A further damper 24, similar in construction and operation to damper 28, may be fitted in the cold air inlet upstream of damper 22 to maintain the cold air inlet pressure constant. During winter operation' the air pressure in supply line 32 is insufficient to operate a motor 102, but in summer this pressure is increased to operate the motor and the phasing of the damper 15 is changed, as shown dotted, and cold air is also supplied through duct 20.

Title: Data processing equipment
IPC: G06F11/34
Filed: 1976-03-04
Abstract: In order to simplify the charging and accounting procedures in a telephone network and, at the same time, to carry these out in a more reliable manner, the system exhibits a multiplicity of switching devices (11, 12, 18; 21, 22, 28; 31, 32, 38) with keyboards and display devices. These are connected group by group to control devices (10, 20, 30) for the user which respond to commands keyed in in order to obtain data from peripheral storage devices and to record details of the telephone connections on magnetic tape. Each control and peripheral device exhibits microprocessors for controlling the individual functions and carrying out tests which determine the operating states of the devices and generate relevant display signals. All these devices are connected to a monitor (6) for recording these display signals. Each device can exhibit a monitoring clock generator with a counter. The latter is regularly incremented and periodically set to zero, responding to a software command. Thus, when a central processing device enters a software loop, the counter exceeds a threshold value and generates a signal indicating the presence of such a loop. The same timing generator can also reset the central processing device into a starting position and delete all data recorded as consequence of a program execution up to this time. Finally, there can be a diagnostics device so that a technician can carry out routine checks of the individual devices. <IMAGE>

Title: Improvements in or relating to the manufacture of artificial silk and the like from cellulose derivatives
IPC: D01F2/30
Filed: 1921-03-21
Abstract: In the manufacture of artificial silk &c. from solutions of cellulose acetate, nitrocellulose, or other ester, ether or derivative of cellulose by a dry-spinning process, the spinning solution is composed of the cellulose ester &c. a mixture of one or more low boiling point solvents or liquids and a solvent or solvents of high boiling point, and the filaments or threads are drawn out during the spinning, the high boiling point solvent retarding the solidification of the filaments and facilitating the drawing-out; also larger jet orifices can be employed for the production of a given denier.  The use as high boiling point solvents of tetrachlorethane and like toxic chlorine derivatives is excluded.  Suitable high boiling point solvents are acetone alcohol, acetylacetone, diacetone alcohol, and cyclobutanone; such solvents are used in an amount not greater than 50-100 per cent of the weight of the cellulose ester &c.  Acetone and methyl acetate are suitable low boiling point solvents; but the latter may be in whole or in part replaced by organic diluents of similar volatility.
