Title: Improvements in or relating to electrical propulsion of ships
IPC: B63H23/24
Filed: 1930-05-07
Abstract: 352,615. Transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COATES, H. J., of General Electric Co., Witton, Birmingham. May 7, 1930, No. 14059. Drawings to Specification. [Class 38 (iv).] Electric motors driving different propellers of a ship are connected to one or other of two bus-bars supplied from two separate turbo-alternators. A controller is provided for each alternator and when it is in its first position the turbine runs at 1/30 full speed. In the second position the turbine runs at 1/25 full speed, and the alternator fields are doubly excited, and the associated propeller motors run up as induction motors. In the third position the motor fields are excited and the motors pulled into svnchronism. Further movement causes the alternator to be normally excited and controls the speed of the turbines. When the outside propeller motors are fed from the same alternator and the vessel travels round a curve at high speed, an overcurrent or over-power relay is actuated to reduce the steam flow to the turbine, and so prevents the motor on the inside of the curve from being pulled out of synchronism. Means are provided to prevent overloading of the motors or alternators,

Title: Improvements in surgical dressings
IPC: A61L15/54
Filed: 1952-06-04
Abstract: A surgical swab, incorporating an X-ray opaque filament, of the type described in the parent Specification, has the said filament of sinuous or undulating form to assist in detection of the swab. The filament is an elastomer loaded with X-ray opaque material, such as barium sulphate, and is formed into a sinuous configuration during application to a gauze web which is then cut and folded repeatedly upon itself to form the swab.  In order to assist visual detection, carbon black is incorporated in the filament and the folding of the gauze is such as to bring the filament to an outside surface.  In the preferred method of applying the filament to the gauze, the filament is rendered tacky by heating as it is pressed against the gauze and the latter is stretched at the same time to produce the undulations.

During cleaning of a mop the liquid in the container 28, which may be heated by an electric heater 38, is circulated by a pump 40 via pipes 46, 49 through a filter 50 which removes sediment suspended in the liquid. The liquid passes from the filter 50 through a diffuser 64 having outlet apertures directing the liquid circumferentially of the container 28 to produce a centrifugal effect on the liquid in the container which assists the gravity settling.
Patent GB-633731-A (GB)
Title: Improvements in or relating to methods of drying gelatine layers
IPC: G03C1/74
Filed: 1947-05-29
Abstract: A gelatine layer, which after drying has a thickness of at most 100 microns, is dried by subjecting it to the heating action of an electric field, a stream of gas being passed over the layer at the same time to carry away the water vapour produced, and the electric field being of such frequency and strength that the water to be removed is expelled within five minutes.  The process may be applied to photographic films or to gelatine layers for use in making sound tracks by mechanical means.  Rod-shaped electrodes may be arranged parallel to the surface of the layer, and the layer may be guided in such manner that the lines of force of the field extend through the gelatine substantially in the direction of movement.  If desired, the gelatine layer may be stationary and the electrodes may move past it. Preferably the electrodes are arranged so that the gelatine layer is subjected to a field of gradually decreasing strength.  This may be effected by a gradual increase in the distances between the electrodes.  A similar effect may be obtained by a decrease of voltage.  In the later stages of drying the heating effect may be decreased by treating the gelatine with colder air.  The amount of air or other gas is preferably not more than 100 per cent more than that required to absorb the water vapour produced.  The air is preferably passed in the same direction as the gelatine layer.  In an example, a cellulose nitrate film with a gelatine layer coated thereon is passed vertically through an electric field of 15 megacycles/sec. and a power of 80 watts, and air at room temperature is caused to flow in contact with the layer of gelatine.  The rod-shaped electrodes are placed in staggered relation alternately on each side of the film, all those on the same side being connected electrically.  The distance between the electrodes is progressively increased in the direction of travel of the film.

Title: Improvements in or relating to straight-bar knitting machines

Filed: 1944-07-31
Abstract: 588,661. Straight - bar knitting - machines. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. July 31, 1944, No. 14549. [Class 74 (ii)] The knocking-over bits A have their normally free ends supported in tricks in a bar E which is interconnected with, and moves with the knocking-over bar B in which the bits are mounted. Thus, the bits are supported and, in turn, support the needles whilst the latter are withdrawn from the sinkers in running on a blank prior to knitting heel tabs. The knocking-over bar may be behind the needle bar C, Fig. 1, or in front of it, Fig. 4. In either case, the bar E is carried by arms F pivoted to arms D supporting the knocking-over bar. The bars B and E may thus be separated to give access to the needle bar; but at other times they are connected, to move together, by releasable straps or by a disengagable spring-pressed catch and pin H, J. Up-and-down motion is given to the knocking-over bits by a cam on the mainshaft O which rocks a shaft N having secured thereto arms M carrying the knocking-over and tricked bars. The in-and-out motion of the knocking-over bits is obtained by a link P connected between an arm Q on the knocking-over bar B and one arm of a bell crank lever R which is rocked by a cam on the main shaft. When the presser arm S is moved to move the needles clear of the sinkers, a swell S<1> engages a pin P<1>, so lifting a slot in the link P clear of a pin T, to disengage the link P from the lever R; the knocking-over bits can then move forward with the needles.

Title: Improvements in hydraulic shock absorbers for motor vehicles

Filed: 1967-03-30
Abstract: 1,185,202. Hydraulic shock-absorbers. T. TAKAGI. 30 March, 1967 [30 March, 1966], No. 14667/67. Heading F2S. In a valve assembly of a conventional hydraulic shock absorber, Fig. 1, having e.g. two sets of passages 11, 13 in a pistol 10 controlled respectively by spring-loaded one-way valves 12, 14, the spring 15 for the valve 14, which controls the flow of fluid from an upper (20) to a lower (24) chamber of a working cylinder (1) is compressed in accordance with the pressure developed in the upper chamber on extension of the shock-absorber, the lower end of the spring 15 bearing upon a vertically slidable sleeve 18 an under face of which communicates with the upper chamber (20) by way of passages 19, 21 and a restricted passage 23, the arrangement being such that the pressurized hydraulic fluid is able to exert a greater force on said slidable sleeve 18 than on the valve 14 in an opening direction. The sleeve 18 is urged downwardly by the spring 15 on to an abutment surface on a cylinder 16 which is secured by a nut 17 to a piston-rod 7, the effective area of the sleeve 18, which is acted upon by the fluid from the restricted passage 23, being larger than that of the valve 14. For relatively slow upward movements of the piston 10, since the upward force of the sleeve 18 is greater than the downward force of the valve 14 the valve 14 remains closed until the spring 15 has been preloaded by an amount equal to the distance l after which the valve 14 opens to develop a relatively large damping force. If the piston 10 moves upward at high speed the restricted passage 23 prevents short time constant pressure build ups at the abutment surface of the sleeve 18 so that the pressure on the valve 14 predominates and the latter opens with the spring 15 having little, or no, preloading and the shock-absorber developing a smaller damping force. In a modification, Fig. 3 (not shown), the passages (13) have restricted portions so that an increasingly large damping force is developed in the region of the higher piston speeds, the lower end of the passage (19) being provided with a relief valve (25) so that the maximum value of the damping force can be limited.
