Title: Improvements in or relating to blasting and like detonators
IPC: C06B45/02
Filed: 1941-09-19
Abstract: 572,729. Blasting detonators; explosives. IMPERIAL CHEMICAL INDUSTRIES, Ltd. (Du Pont de Nemours & CO., E. I.) Sept. 19, 1941, No. 12033. [Class 9 (ii)] A detonator having reduced liability to detonate as the result of accidental exposure to a flame or spark when its end is open, comprises a fuze or electric ignition and a compressed composition of needle-like crystals of diazodinitrophenol of a " grist modulus " between 1.0 and 2.0 obtained by passing the crystals through standard Tyler sieves of 100, 150 and 200 mesh. The crystals should be free from ingredients capable of detonating on mere conflagration in an open detonator, such as mercury fulminate, lead azide and the like, but should be capable of detonation under confinement in a closed detonator. An easily ignitable deflagrating composition incapable of detonation, such as lead sulphocyanide or basic lead salts of 2-mono-nitroresorcin or basic lead salts of 3 : 5-dinitro-2-hydroxytoluene prepared as described in Specifications 312,952, [Class 9 (ii)], and 473,146, may be superposed above the crystals which fill a recess in the main charge. The diazodinitrophenol may bo used alone or may be mixed with an oxidising agent such as potassium chlorate, and the detonating mixture is preferably used with a base charge incapable of detonation by mere conflagration, such as tetryl, pentaerythritoltetranitrate, hexanitromannitol and the like. The " grist modulus " is obtained by taking a single sample of the material and sieving this successively through the 100 mesh sieve and then through the 150 and 200 mesh sieves, adding together three times the fraction retained on the 100 mesh sieve, twice the fraction retained on the 150 mesh sieve and the fraction retained on the 200 mesh sieve and adding unity to the result. The whole of the detonating material may be compressed or only part of it.

Abstract: 628,894. Casting concrete walls in situ. FINNEMORE, F. May 5, 1947, No. 12041. Convention date, May 27, 1946. [Class 20 (ii) ] A travelling mould for casting walls in concrete comprises side walls 1, 2 and a front plunger-like wall 3 which is adapted to be forced against the freshly moulded sector by a lever 11 which is supported on the side walls, which are thus drawn forward to a new position, the mould being supported on a lower course of the wall by pivoted projections 18. The side walls are secured together so that the distance between them is adjustable, by overlapping U-shaped brackets 7 secured together by bolts 4. Wheels 21 on a telescopic shaft covered by the side walls support the mould on a lower course. To ensure bonding of successive courses a blade 40 on one bracket 7 scrapes a groove in the upper surface of the concrete, and the front and rear plates 3, 15 of the mould are provided with projecting pieces to form vertical grooves and holes 43 for reinforcing wires. The side walls have the lower edges slightly farther apart than the upper edges and the near ends than the front ends to facilitate withdrawal of the mould. For constructing a circular wall the mould is guided by a radius bar pivoted on a centre pole and also supported by a chain connected to the centre pole.

Patent GB-1189974-A (GB)
Title: Improvements in Electrical Waveguide Arrangements
Inventor: CRAVEN GEORGE FREDERICK
IPC: H01P1/219
Filed: 1969-03-07
Abstract: 1,189,974. Filters and switches. STANDARD TELEPHONES & CABLES Ltd. 7 March, 1968, No. 12220/69. Heading H1W. A band-stop filter comprises a rectangular waveguide having an H-plane bifurcation dividing the guide into two branches one of which is effectively dimensioned beyond cut-off. As shown, the rectangular waveguide 1 is divided, over a certain length 21, by a central H-plane septum 2 into two waveguides 3, 4 of reduced height. The waveguide 4 has a width equal to that of waveguide 1 and propagates in the normal manner. The width of waveguide 3 is reduced, e.g. by thickening the narrow walls, to such an extent that its cut-off frequency lies above the operative frequency and only an evanescent wave is propagated in it. It can be shown that a length l of such a waveguide presents an inductive reactance to the wave whereby if the length is terminated by the conjugate capacitative reactance, it behaves as a tuned section and there is full energy transfer within a certain pass-band. Each length l is provided with a capacitative tuning screw 7 whereby the waveguide 3 behaves as a two-section band-pass filter. Each section is associated with a phase-shift of #/2 so that, if the septum 2 has a length equal to one guided wavelength, there exists a differential phaseshift of # between the waveguides 3 and 4. This results in zero output from the guide 1 at the pass frequency of waveguide 3. At other frequencies, the waveguide 3 ceases to propagate, but since the waveguide 4 propagates at all operative frequencies, an output is derived from the waveguide 1. The device therefore behaves as a band-stop filter. If the narrow walls of the waveguide 3 are loaded with ferrite or garnet, the cut-off frequency may be varied by means of a variable transverse magnetic field provided by a permanent magnet or an electromagnet. This variation enables the device to be operated as a switch. The screws 6 are for matching purposes. The necessary differential phase-shift may be obtained for various lengths of septum 2 and various numbers of sections 1.

Title: Improvements in and relating to coaster hubs
IPC: B62L5/14
Filed: 1935-04-25
Abstract: 434,776. Coaster hubs. FICHTEL & SACHS AKT.-GES., Schweinfurt, Germany. April 25, 1935, No. 12496. Convention date, April 25, 1934. Addition to 420,550. [Class 136 (ii)] A coaster hub having means for locking the driver in the brake - applying position by a coupling- device, in order to avoid continuous back - pedalling, as described in the parent Specification, is provided with a roller locking device adapted to move on ascending tracks in one direction of rotation to lock a surrounding ring by means of which the locking-coupling is closed, the springs which act on the coupling being disposed entirely within the driver. In the form shown, the coupling for locking the driver a consists of a ring-shaped part a<3> fixed to the driver, and an axially-slidable part i<1> on a bar i extending through a transverse slot in the axle b. The parts a<3>, i<1> have coupling teeth with inclined flanks, which are normally held out of engagement by a spring k. A bar g acted on by a spring h slides in a transverse slot in a bearing cone b<1>, and is guided by a pin g<1> in the bore of the axle b. An end cap c is provided with several (e.g. three) internal arcuate projections c<1> formed at their ends which are the leading ones in the backward rotation of the driver with inclined surfaces c<2>, Fig. 3, the other ends forming undercut teeth c<3>. Opposite these projections is a ring d formed with corresponding projections d<1> having inclined surfaces d<2> and undercut teeth d<3>. Within the ring d is a cage e, Fig. 2, (with drag springs e<2>) carrying rollers f, which on back-pedalling move outwards on flats b<2> on the cone b<1> until they enter depressions d<4> in the ring d, which is thus locked against rotation, enabling it to be traversed by the inclined surfaces c<2>, d<2>, to displace the bar g and, through the spring h (which is stronger than the spring k), the bar i, thus closing the locking-coupling i<1>, a<3>. Since the teeth of the coupling are inclined, the braking effect may be varied even after the coupling has been closed. In a modification, the coupling and the parts effecting its engagement are all mounted in the bore in the driver, on the inner side of a ball bearing supporting the driver, the sliding bars being replaced by sliding parts around the axle, which is itself formed with the flats for actuating the locking-rollers.
