Abstract: 345,903. Fusible cut-outs. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hewlett, E. M. ; 70, Union Avenue, Schenectady, New York, U.S.A.) June 30, 1930, No. 19868. Convention date, June 28, 1929. [Class 38 (i). A fuse 8 is clamped between metal discs 14, 16 and an insulating disc 13 by means of a metal plug 15 screwed into a metal housing 11, which is in turn screwed to an insulating tube 10 containing a conductor 17, which may also be fusible, under tension of a spring 18. The conductor 17 is connected at one end in a circuit 4 to be protected, and at the other to an intermediate point of the fuse 8, so that the current divides through the two parts of the latter. The spring 18 is stated to eject the conductor 17 from the tube 10 on rupture of the fuse 8.

Abstract: 720,395. Surgical splints. AIRSCREW CO. & JICWOOD, Ltd. Nov. 21, 1952 [Aug. 23, 1951], No. 19875/51. Class 81 (2). A surgical splint is made by moulding or otherwise forming a core, applying thereto by wrapping one or more layers of resin-impregnated fabric and allowing the impregnated fabric to harden or become hardened. A core a preformed to the shape of the splint is wrapped in glass fabric b secured in place by a helically wound strip d of resin-impregnated glass fabric. If the core a is to be removed, it is made of wax or plaster of paris. Where the core a is to be an integral part of the structure it is made of paper, wood pulp or waste glass fibre any of which may be impregnated with synthetic resin or other bonding agent. The foot-engaging portion g of a leg splint is formed by enclosing a preformed core a with sheets i of impregnated glass fabric in a two-part mould h, a connecting web i<1> being formed. The foot-engaging portion g may be secured to tubular side members f by sockets. Resinated asbestos felt, cellulose nitrate or acetate, or methyl methacrylate may be used instead of glass fabric. It is possible, by this means to make splints which are semitranslucent to X-rays.

A stable load-supporting structure shown diagrammatically in Fig. 6 comprises an elongated vertical hollow member 20 having its bottom end fixed solidly in the earth 21, the strength and stability of said hollow member being sufficient to support only its own weight and any external load or forces W imposed on it, and a tension member 23 for carrying additional weight M below the bottom end of the hollow member, the combined loads carried by the hollow and tension members exceeding that which the hollow member alone may support as an external load without buckling, the tension member 23 being attached to the centre of the upper end of the hollow member 20 and having a small clearance within the hollow member at at least one point intermediate its ends (in Fig. 6 there are a plurality of such points by virtue of stabilizing members 25), so that the tendency of the hollow member 20 to bend due to the additional weight M brings said members into contact at least at said one point to prevent increased bending of the hollow member by the additional weight. In Fig. 11 (not shown), the invention is utilized for marine drilling. The hollow member 20 is a caisson within which the tension member 23 is the surface casing of a diameter to have only small clearance with the inside of the caisson and provided with stabilizers 25. The drilling head 45 is attached to the top of the casing 23 and to the drilling vessel 35 anchored centrally over the caisson 20. In the embodiment of Fig. 12 (not shown) the caissons 20 support a platform 41 above the surface of water 32, the platforms carrying equipment such as storage and separator vessels 42, 43. In Fig. 13 (not shown) the caisson comprises two concentric tubular members 20a, 20b connected by braces 50 which may be bulkheads providing buoyancy compartments 51 and flooded compartments 52.

Title: Improvements in or relating to electric motor controllers

Abstract: 410,642. Master control of A.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Seeger, E. W., and Lassen, E. U. ; North 12th Street, Milwaukee, Wisconsin, U.S.A.) July 17, 1933, No. 20156. Convention date, July 15, 1932. [Class 38 (iii).] A two speed motor M is connected for high or low speed operation by means of a switch 10, and reactors 3, 4, 5, in the main motor circuit, are provided with direct-current windings W<2> by which the reactance values are varied. When a master switch 12 is moved in one direction or the other, the windings W<2> are first energized through resistances r, r<1>, and then one of two motor reversing switches 1, 2, is closed and the resistances r, r<1>, cut out, so that the motor accelerates to its low speed. If the switch 12 is then moved to its high speed position, the switch 10 is energized and the high speed winding S<1> of the motor connected through the reactors 3, 4, 5, which are then short-circuited by closure of a switch 11, which acts through relays 9, 15, 17 and 18, to open a relay 16 to disconnect the windings W2. If the switch 12 is moved directly from the " off " to the " high-speed" position, the motor accelerates to its high speed under the control of the reactors, the relay 15 operating after the current in the windings W<2> has reached a certain value, to cause the switch 11 to close. When the switch 12 is returned from its " highspeed" to its " low-speed " position, the low speed winding S of the motor is connected in circuit and the switch 11 opened, so that the winding S is in circuit with maximum inductance. The opening of the switch 11, however, causes the relay 9 to close and energize the windings W<2>, and as the direct current builds up the motor is gradually braked. If the switch 12 is thrown directly from the " high-speed " to the "off" position, the motor remains connected to the supply and is braked smoothly until the current in the windings W<2> reaches a certain value whereupon the relay 15 causes the disconnection of the motor. Specification 381,123 is referred to.

Abstract: 662,825. Indicators for displaying variable information. BULMER'S (CALCULATORS), Ltd., and SALMON, F. N. April 6, 1950. [Aug. 4, 1949] No. 20337/49. Class 118 (i). In an information displaying device of the kind in which a number of panels provided with information on their faces are mounted to pivot about a vertical support, the support is provided at both ends on the front face with corrugated strips to form outwardly facing recesses into which the pivot pins of the panels are inserted and retained by guard strips which partly cover the corrugated strips. Figs. 1 and 2 show an information display for standing on a desk and for mounting display panels as shown in Fig. 3. Corrugated strips 7, 8 are secured to the upper and lower ends of the vertical support 1 the lower strip 8 having its lower edge overlapped by a lip 3a of a flange of the lower closing plate 3 and the upper strip 7 is partially covered by the upper closing plate 2. The display panels are secured by inserting the upper pin 13 in one of the grooves between members 2 and 7 and then swinging the lower pin for insertion in the corresponding groove between members 3 and 8 the panel then dropping until the lower pivot pin abuts the flange of plate 3 which supports lip 3a. In order to securely lock the display panels into position and yet provide for their being easily removed or inserted when required an angle plate 15 is guided for sliding movement by pins 16 secured in its top surface which pass through apertures in the top surface of member 2 and in brackets 17 secured to the sides of support 1. The pins 16 are encircled by springs 18 which abut the lower ends of brackets 17 at one end and pins 19 at the other so that the plate 15 is urged upwardly. The plate 15 can be locked in its lowered position by means of a bolt 20 which slides and is supported in apertures in the front of member 2 and in a bracket 21 which is secured to the back surface of the front of support 1. The bolt 20 passes through a keyhole slot 22 in angle plate 15 only the plain and reduced part of the bolt shank 20a passes through the reduced portion of slot 22 whilst the enlarged portion of the slot will receive the enlarged portion 20b of the bolt. The bolt is spring loaded by means of a spring 23 so that if the bolt is pulled outwardly against the spring, plate 15 will move upward under the action of springs 18 so that the display panels may be removed or inserted. Support 1 is slightly rearwardly inclined so that the panels will stay in the position into which they are moved and arms 25 limit the swinging movement of the panels. In a modification Fig. 4 (not shown) the base 6 is omitted and a bracket is provided to facilitate mounting the device on a wall.
