Title: Improvements relating to the actuation of machines for setting the fuzes of projectiles
IPC: F42C17/00
Filed: 1930-04-04
Abstract: 351,124. Setting projectile fuzes. SCHULER, H., 10, Molkestrasse, GIETMANN, A., 24, Golzheimerstrasse, and RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, all in Dusseldorf, Germany. April 4, 1930, No. 10781. [Class 9 (i).] A fuze-setting machine, of the kind in which the gearing for setting the fuze is actuated by the discharge of an accumulator which is charged by the kinetic energy of the recoiling gun barrel, has the accumulator connected to the barrel by a flexible and elastic gearing. According to one construction, a conical drum d, Fig. 1, is mounted on the gun carriage a<1> and is connected to the gun barrel by a flexible cord or rope d<1>. The rotary movement of the drum, when the barrel recoils, is transmitted to a rack c<1> by a shaft d<2>, a worm d3, a worm wheel d<4>, a lever d<6> mounted on the spindle d<5> of the worm wheel, and an arm d<8> pivoted to the lever d<6>. This lever engages with a roller c<2> resiliently mounted on the rack C<SP>l> and moves the latter from left to right on the recoil of the barrel. On the return movement of the lever d<6>, produced by a torsion spring in the drum d<1>, the lever end d<8> slips past the roller c<2> by pivoting about the pin d<7>. The rack c<1> is connected to a piston c<6> reciprocable in a fluid-filled chamber c<5> of an accumulator c. The chamber c<5> communicates with a reservoir c<3> by passages c<8>, c<4>, the latter being normally closed by a spring-pressed valve c<o>. In operation, on the recoil of the gun barrel, the fluid in the chamber c<5> is forced into the reservoir c<3> through the passages c<4>, c<8>, the valve c<0> having uncovered the passage c<4>. On the disengagement of the lever d<8> from the roller C<SP>2>, the valve c<0> closes the passage c<4> and the piston starts its return movement together with the rack c<1>. The latter sets in motion a train of wheels c<9>, b<1> .. b<5> which operate the fuze-setting mechanism, the wheel c<9> being mounted to run idly on its shaft in the movement of the rack from left to right. The speed of the return movement of the piston can be regulated by an adjustable opening in the passage c<8>. In a modification, the energy of the recoil of the barrel is transmitted to the piston by the displacement of fluid in a device connected to the gun, the displaced fluid being led to the left-hand side of the piston c<6> to force the latter to the right. In a further modification, the displaced fluid is led to the back of the piston by a pipe f, Fig. 4, through a non-return valve i and the energy is stored by a spring h.. The speed of discharge is regulated by an adjustable opening in the discharge passage k.

Title: Improvements in or relating to coils for the reception or transmission of radiated power
IPC: H03H5/00
Filed: 1933-04-18
Abstract: 421,564. Inductances. BROWN, S. G., 64, North Gate, Regent's Park, London. April 18, 1933, Nos. 11367 and 26217. [Class 37] A receiving or transmitting inductance coil is provided, for the purpose of augmenting its inherent capacity, with a series of longitudinal conductors extending within the coil and /or outside it. On a tubular insulating former 1, Fig. 1, is mounted a series of longitudinal conductors constituted by metallic strips 2 connected together by a metal band 3 which is preferably not closed on itself. Around these strips is wound the coil 4 of insulated wire or strip. One or more sliders 6 are provided for making contact with any turn of the coil. As shown, the coil 4 is connected between the grid of a thermionic valve 7 and earth, the band 3 being connected to the aerial 8. Alternatively the coil may be connected between the aerial and earth, the band 3 being connected, either directly or through a variable condenser, to earth. A core 5 of magnetic material, which may be variably inserted into the coil, may be provided for tuning purposes. This core may be made from powdered iron or nickel or the metal known under the Registered Trade Mark " Mumetal," which is oxidized, preferably with chromic acid, mixed with a binder such as resin or cement, and pressed in a mould which may be heated. Cams, screws, lovers, or other mechanical means may be provided for adjusting the core, and a pointer and dial may be provided for indicating the adjustment, and the corresponding wave length or station. Fig. 4 illustrates the manner in which the coil is employed for selective reception. Two waves of slightly different wave-lengths each produce a series of stationary waves. One series has points A of maximum receptivity, the second series having similar points B at intervals different from those between the points A. By placing the slider 6 at a point of maximum receptivity of one series most widely separated from adjacent points of the other series, minimum interference from the second series is obtained. Instead of the contacts 6 one or more axially movable secondary coils may be employed to provide an inductive connection. Wire may be used instead of metal foil for the longitudinal conductors 2 ; these may be of wire or strip of high resistance. The convolutions of the coil 4 may be spaced apart at the ends to prevent reflection at the ends. The pitch of the turns of the coil may be varied along the length of the coil to enable the rate of variation of the inductance and capacity for a given movement of the slider to differ at different positions on the coil. For fine adjustment conductive connection may be made by movement in the direction of the turns instead of across them.

Abstract: 674,328. Electric follow-up systems. JOYAU, G. May 2, 1949. [May 3, 1948] No. 11725/49. Class 40 (i). [Also in Group XXXV] In a single-phase commutator motor with short-circuited brushes, the rotor is mechanically geared to the brushes, or the stator, or stator flux shifting means, so that it can be used as a follow-up system. In Fig. 6, the stator S is turned by an external means whilst the rotor R is geared to the brush rockers so as to drive them in such a direction as to return them to the neutral axis and stop the motor. A modification is described in which rotation of the brushes is used to cause rotation of the stator by gearing from the rotor. Instead of moving the stator itself, the same effect may be obtained by providing it, as in Fig. 9, with a distributed three-phase winding Sr1, Sr2, Sr3, connected to a similar winding St1, St2, St3 excited by a single-phase rotor winding Rt to provide a selsyn system. In Fig. 10, the motor stator windings are fed through inductances b1, b1<SP>1</SP>, b2, b2<SP>1</SP> and b3, b3<SP>1</SP> energized from the mains supply and embraced by coils B1, B1<SP>1</SP>, B2, B2<SP>1</SP>, B3, B3<SP>1</SP>, fed from the transmitter selsyn. This is stated to reduce the load carried by the cables between transmitter and receiver. In a modification, the transmitter is a circular potentiometer tapped at three equally spaced points and fed by diametral rotatable brushes fed with D.C. Arrangements are described for controlling larger power units by means of the system, a fine and coarse control being used if desired.
