Abstract: 457,150. Spiked plates. THEODORSEN, O. T., 8, Kirkegaten, Oslo, Norway. Jan. 13, 1936, No. 1106. Convention date, March 30, 1935. [Class 89 (ii)] A spiked plate for joining wood of the kind having teeth alternately bent to opposite sides is produced from a blank having a zigzag shaped edge, the teeth being formed by incisions cut through the corners of the blank. Incisions 5 are made in a polygonal blank 1, Fig. 2, and the teeth 4 thus formed bent out of the plane of the plate about the lines 6. An aperture 2 for the connecting bolt of the wood parts and apertures 3 for fastening screws are provided.

Filed: 1942-02-02
Abstract: 582,978. Gas turbines. WHITTLE, F. Feb. 2, 1942, No. 1396. [Class 110 (iii)] The exhaust from a gas turbine 2 passes through an annular space, between.an outer shell 3 and a central conical shell 7, to an exhaust pipe 6 which may lead to a propulsion jet. The conical shell is positioned and held by two pairs of radial rods 11, 12 at right-angles. The pairs of rods may be enclosed in streamlined fairings 16 which may be assymetrical and fixed at an angle to correspond with or correct the direction of the gas stream or each rod may have an individual fairing which may be rotationally free to lie in the direction of the stream. The rods 11, 12 have a small longitudinal freedom and are not secured to either shell. The fairings 16 are welded to one only of the two shells.

Title: Improvements in or relating to machines for applying caps to bottles and other containers
IPC: B67B5/03
Filed: 1932-01-18
Abstract: 390,591. Capping bottles. SYMONS, A. B., Northumberland Park, and FORD, R. E., 12, City Road, both in London. Jan. 18, 1932, No. 1459. [Class 125 (ii).] A machine for applying skirted caps made of paper or the like to bottles comprises means to hold the cap over the mouth of the bottle, rolling or wiping means to apply an adhesive strip around the cap, and means to sever the strip. As shown in Fig. 1, the cap-holding means comprises a head 31 which is rotated through gearing 27, 28, 29 by a handle 25<1> fastened to a shaft 25 which also rotates, through gearing, 27, 28, 33, a vertical shaft 34 carrying two cams 35, 36, which co-operate with rollers 35, 36 on two frames 37, 51 pivoted at 38. Secured to the shaft 25 is a cam 23 having a depression 24 engaged by a roller 22 mounted on the junction of an arm 16 and a link 15. The link 15 is connected by mechanism comprising a rack and pinion to the bottle rest 10. When the handle 25<1> is grasped and given one complete turn, the following movements occur :-The roller 22 is disengaged from the depression 24 and a spring 21 connected to the arm 16 pulls the link 15 upwardly and so raises the bottle 11 into the head 31 which is simultaneously put into rotation. The cams 35, 36 are rotated and allow springs 39, 52 to rock the frames 37, 51 anticlockwisely. This movement brings the strip-applying roller 45, which is carried on the frame 37, with the end of the tape 41 into engagement with the cap skirt the tape and skirt being pressed against the bottle neck as the bottle rotates. The cams 35, 36 have now rotated so that they begin to force the frames 37, 51 to rotate clockwisely, and a toothed segment 46 on the frame 37 coacts with and rotates a sleeve 47, a knife on which severs the tape. Before the frame 51 moves away an additional roller 53 carried thereby finishes the application of the severed strip 41 to the cap and bottle. In a modification the finishing roller 53 is replaced by a pad, the tape, which is pulled taut before severance, is applied to a knife, and the head is lowered instead of the bottle being raised.

Title: Improvements in snap or impulse couplings for magnetos
IPC: F16D5/00
Filed: 1942-02-06
Abstract: 552,792. Impulse couplings for magnetos. HASLER AKT.-GES. WERKE FUR TELEPHONIE UND PRAZISIONSMECHANIK. Feb. 6, 1942, No. 1576. Convention date, Jan. 3, 1941. [Class 35] In an impulse coupling for magnetos especially multi-pole magnetos in which the magnetic drag of the field circuit is used to stress the coupling spring which is relaxed to give the impulse when the drag is overcome (so that detaining pawls are dispensed with), additional centrifugal and brake devices are incorporated in the coupling to allow of automatic and manual timing. The volute spring 4 is fixed at one end to the cupmember 2 of the coupling on the magneto shaft and the other end to the disc member 3 which is capable of some rotary movement on the sleeve 2a of the member 2 and is driven by the engine. The movement is limited by projections 36 on 3 extending into slots bounded by projections 2b on 2. Centrifugal weights 6 pivoted at 7 on 3 and controlled by springs 9 have noses 6a in engagement with projections 2b. At starting, the spring is wound up until by engagement of the teeth 2b, 3b the drag is overcome (in the fully retarded position) and the spring then provides a sparking impulse. Thereafter, at speed, the centrifugal weights determine the relative positions of 2b, 36 to advance the timing in accordance with the speed. A retarded timing is provided for by a manually-applied brake 12 on the cup-member 2. The weights may be arranged to retard the advancement of timing with increase of speed.

Title: Improvements in or relating to anchoring devices

Abstract: 944,677. Friction grip-fastenings; prestressed concrete, anchorages. CONSTRUCTIONS EDMOND COIGNET. Jan. 16, 1962 [March 2, 1961], No. 1586/62. Headings E1V and E2A. [Also in Division D1] A device for anchoring one end of an assembly of wires 21 comprises an elongated sleeve 16 formed with a bore 17 for receiving the wires, an elongated rod 10 for fitting into the end of the assembly so that the wires are distributed about the rod, the rod being formed with an integral head 13, having an abutment face 14 arranged to bear against the ends of the wires, and the rod and sleeve being made of a material having elastic properties similar to the elastic properties of the wires, whereby forced insertion of the rod and distributed wires into the bore wedges the wires between the rod and the wall of the bore to anchor the end of the assembly of wires in the device. The rod has a stem with a cylindrical part 11 and a frusto-conical end 12 and -head 13 is also cylindrical and of greater diameter. To use the device the wires to be anchored are positioned around the stem so that their ends are in contact with the face 14 and a ring 22 is then slid over the wires until it abuts the face 14, the function of this ring being to prevent buckling when the wires and rod 10 are forced into the bore 17. The wires are compressed between the bore 17 and rod during the insertion and are held solely by the friction between the wires, the wall of the bore and the surface of the rod. The force required to insert the wires and the rod 10 into the bore is however less than that required to pull the wires from between the sleeve and rod since during the insertion the wires and the rod move together relative to the sleeve whereas to pull the wires out the friction between the wires and both the rod and sleeve must be overcome. Transverse serrations can be formed in the surface of the stem to increase the friction. The rod and bore can be other than circular in cross-section.

Vacuum tubes.-The removal of occluded gases from the electrodes, leads, &c. of a discharge device during evacuation is effected by connecting the electrodes in a circuit resonant at a predetermined high frequency and supplying current of that frequency to the circuit, the current being independent of that in the device due to filament emission, but dependent on the capacity between the grid and the anode. In the form shown in Fig. 1, a pump 5 is connected to a discharge tube 1 through a liquid-air trap 7 and a tube 6, and the high-frequency oscillating circuit for use therewith, of 60,000 kilocycles, includes a grid 3, an anode 2, inductances 8, 9, and a condenser 11. Chokes 12, 13, 14, 15 are inserted in the electrode leads, while a grid leak 17 is connected between the grid lead and the secondary of the transformer 16. A potential of 500 volts between the anode lead and earth generates in the oscillatory circuit currents of low power factor and having a magnitude of from 5 to 30 amperes. Current is supplied to the cathode 4 through a transformer 16.
