Title: Improvements in or relating to fuzes for shells
IPC: F42C9/16
Filed: 1944-11-15
Abstract: 585,769. Projectile fuzes. HYDRAN PRODUCTS, Ltd., and MOTLEY, L. Nov. 15, 1944, No. 22603. [Class 9 (i)] A slow fuze train is started, for destroying the projectile after a given interval, by the rotation of a body of asymmetric weight about an axis transverse to the spinning axis of the projectile, in response to the spinning of the projectile. In the form shown, a cylinder 1 is mounted for rotation about the axis II-II at right angles to the spinning axis of the shell, and is normally held in " safe " position, in which the bores 2, 4 and 9, 10 are out of alignment, by a coiled spring. As the shell commences to spin, the asymmetry of weight of the cylinder causes it to rotate into the " armed " position shown, in which instantaneous trains in the bores 9 and 10 are in communication for normal detonation by a striker 7. At the same time the plunger 5 enters the bore 2 and the detonator 6 strikes the pin 3 and ignites a slow train running up a passage (not shown) in the plunger and eventually, through passage 20, joining the instantaneous train in the bore 9. The plunger 5 is normally pressed lightly on a flattened portion of the cylinder 1 by a weak spring 11 ; when the cylinder has rotated and the plunger commences to descend, the balls 15 slip out of their recesses in the body of the fuze and into the recess 16, so that the plunger and sleeve 14 are pressed down together by the powerful spring 12. It is stated that the asymmetry of weight of the cylinder results from the holes therein, but other means may be provided. According to the Provisional Specification, the pin 3 is movable in the cylinder and is normally held cocked against a spring by the rounded end of a rod engaging a V-shaped groove in its poriphery.The other end of the rod abuts against the fixed fuze body, but when the cylinder rotates into " armed " position the rod registers with a hole and enables the pin to move forward and strike a fixed detonator. In this form the main detonator is carried by the cylinder.

Title: Clock-controlled display apparatus
IPC: G06C1/00
Filed: 1935-08-14
Abstract: 461,265. Changing signs. ADAMSON, H., YOUNG, A., MUIR, A. Y., and MUIR, J. Y. Aug. 14, 1935, No. 22849. [Class 3 (i)] A clock - controlled time - table comprises a non-endless display band 8 wound on and off two storage rollers 1, 2. A step-by-step motion is imparted to the roller 1 by a rotating arm 11 which at each revolution contacts with one of a series of radial pins 17 extending from the roller 1. at one side thereof. A gravity detent 18 prevents backlash. The arm 11 is driven by an electric motor 10 through reduction gearing, and in its rotation also lifts a pivoted arm 42 coupled to a crank 40 on a shaft 35 furnished with other cranks 34 which through rods 36 lift an apertured shutter 31 to conceal the band 8 during its movement. In the final part of its revolution the arm 11 turns a star-wheel 58 through 90‹, and this switches off the motor till clock mechanism re-starts it. Fig. 5 shows the switch arrangement. Stationary quadrant contacts 52, 53 are brought in succession into circuit with a stationary segment contact 54 by a brush 56 carried by the star-wheel 58. Stationary segments 50 in electrical contact with one another, and intermediately disposed segments 51 similarly in contact, are touched in turn by a brush 451 on the minute hand 45. The segments 50 and 51 are respectively connected to the quadrants 52 and 53 and the circuit through the motor 10 is completed as soon as the brush 451 snaps down on a segment 50 or 51 via a lead 63, partcircular stationary contact 49, and a brush 441 on the hour hand 44. The apparatus is adapted to be non-effective during the period in which the brush 44<1> bears on the gap between the ends of the contact 49, except for a contact at 68 which allows of the excitation of a solenoid 66 to force up a rod 67 and raise the detent 18, thus permitting the band 8 to unwind off the roller 1 and become re-stored on the roller 2. This return of the band is effected by a weight supported by a cord 21 passing over a pulley 22 and wound around a drum geared to the roller 2, this weight serving also normally to tension the band. A brake controlled by a centrifugal governor regulates the speed of re-wind. The shutter 31 can be slid laterally by hand to bring its apertures over any desired column of numerals &c. displayed on the band 8, or clockwork may be employed to effect this movement either mechanically or electrically. Stationary display tablets are provided on the casing, and a clock 86 may be fitted. Advertisements may be displayed on the band 8 and on the shutter 31.

Title: Improvements in or relating to electric cables for high frequency
Inventor: WESTON WILLIAM KIRBY
IPC: H01B11/18
Filed: 1945-09-07
Abstract: 650,428. Air-space cables. STANDARD TELEPHONES & CABLES, Ltd. Sept. 7, 1945, No. 23145. [Class 36] A large diameter coaxial cable comprises a hollow inner conductor in the form of a continuous cylinder built up of one or more metallic tapes folded longitudinally, the inner and outer conductors being spaced by one or more helices of low loss dielectric material wound round the inner conductor. Preferably the material of the spacers is hollow or corrugated to reduce the amount of solid dielectric required.. Hollow tubes 3 of low-loss dielectric material, e.g. solid ethylene polymer, are wound round the inner conductor 1 which is formed from a single copper tape folded longitudinally so that its edges abut at 2; the tubes 3 may be wrapped with insulating tape 4. In Fig. 1 adjacent turns of the tubes 3 do not touch, a second group of helical spacers 5, which may be wrapped with insulating tape 6 and which have corrugated cross-sections, being wrapped about the first group, the lay of which is opposite to that of the second group ; the first group holds together under pressure the edges 2 of the inner conductor, the second group serving as additional spacers. The hollow inner conductor 1 may accommodate a conductor 8 spaced from it by washers 9. In Fig. 2 a single group of six helices 3, touching one another, secures the inner conductor edges 2 and also provides spacing means ; these helices are of the same diameter as the inner conductor 1, giving a ratio of outer/ inner conductors of 3 : 1 if the thickness of the tape 4 is neglected. To obtain a minimum attenuation constant, i.e. have a ratio of 3.6: 1, and also to maintain the helices in contact with the inner conductor and with one another, the helices 3 are made oversize and are squeezed into position, thus deforming their cross-section so that they take up the extra radial space necessary for the correct ratio of diameters. Specifications 650,425 and 650,427 are referred to.

Title: Improvements in and relating to the manufacture of cores for hollow metal castings
IPC: B22C9/10
Filed: 1937-08-24
Abstract: 501,345. Casting slip. CRONING, J. Aug. 24, 1937, No. 23242. [Class 87 (ii)] [Also in Group XXII] A core for use in casting metal is made by pouring a slip made from clay, kaolin, quartz, chamotte, barium sulphate or the like into a two part plaster of Paris mould and, after allowing sufficient time for the deposition of a hollow core, pouring out the excess. The core contracts from the mould during drying and car then be removed. After use the core can be removed from a casting, by shaking out if it sinters and breaks, this being favoured if the core is thin, or by disintegrating in water if o a material, such as .fatty clay or kaolin, which contracts more rapidly than the cast metal. The porosity of the core can be increased by adding to the slip granular naphthalene or other material which can be gasefied by heat before or during. casting or by perforating the core while plastic. This may be done by a hand guided tool having pins h reciprocated by a cam c on a shaft b driven at 2,000 revolutions per minute. The holes may be about 6À1 to 0À2 mm. in diameter to avoid penetration by the molten metal.

[Class 38(iii)] A control system comprising, for example, a number of traction motors has a main circuit breaker, the coil of which is energized through a contact of a timedelay relay which has two operating-coils. One coil of the time-delay relay is excited by a continuous current when a master controller is moved from the " off " position. Movement of the controller to the " off " position breaks this current and energizes a pilot motor to return a camshaft, controlling contactors in the main motor circuit, towards a neutral position. During such return movement, the timedelay relay is normally maintained closed by intermittent excitation of its second coil, a current being supplied thereto through segments which are placed on the cam-shaft between the notching positions thereof. If the cam-shaft is halted in a notching-position during return movement, or the pilot motor fails, the intermittent current discontinues and the main circuit breaker opens. Means for independently exciting the coil of the circuit-breaker when the cam-shaft is in the neutral position may be provided.
