摘要： 398,113. Setting projectile fuzes. ROMBERG, H., 76, Geibelstrasse, GIETMANN, A., 124, Golzheimerstrasse, and RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, all in D³sseldorf, Germany. March 15, 1933, No. 7860. [Class 9 (i).] Energy for operating a fuzesetting apparatus is stored in a flywheel. The apparatus shown comprises a pair of fuze-setting devices b , b each having a socket c operated by a handle d , which also sets a lamp indicator d in accordance with a transmitted command of the desired fuze setting, and a second socket c operated by a handle e or motor-operated crank through mechanism similar to that described in Specification 334,550. A gear wheel k in the mechanism between the handle e and the socket c is now connected through gearing l, l , l to a flywheel l , and a free-wheel clutch g is inserted in the spindle of the gear wheel k, so that the flywheel when once speeded up by the handle e can take charge and perform several fuze settings over a prolonged period of time without further operation of the handle e.

摘要： 417,090. Setting projectile fuzes. RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, and GIETMANN, A., 49, Hugo-Viehhoffstrasse, both in Diisseldorf, Germany. Dec. 14, 1933, No. 35219. [Class 9 (i).] In automatic fuze-setting apparatus for projectiles, the projectile is retained in the setting socket by a locking device which is released only upon the issue of an order to fire the gun. The locking bolt b retaining the projectile a in the setting socket (not shown) is under the control of a wedge-ended lever c actuated by a solenoid d which is in circuit with a battery e and contacts for four armatures m, m , m , f, the circuit being completed to release the locking bolt b only when both (1) the solenoids l, l , l are energized consequent on the fuze being correctly set and (2) the solenoid f, which is in circuit with a battery u is energized by the closing of a switch u giving a signal at u for the gun to be fired. The fuze-setting is signalled from a transmitter o having three concentric rows of contacts for units, tens and hundreds of a three place setting figure, and corresponding contact arms r, r , r . A battery q is in series with the contact arms and thence by way of the selected contacts on the transmitter and lines s, t with corresponding contacts on a control k, the circuit being completed through contact arms n, n , n , lines v, v , v , solenoids l, l , l and return lines x q . The contact arms n, n , n are intergeared in the ratio 1 : 10 : 100 and are driven in synchronism with corresponding contact arms i, i , i on an indicator p by means of a crank y and gearing 2, 3, 4, 6, 7. Lamps on the indicator p are in series with the corresponding contacts on the control k so that a signal is given and the solenoids l, l , l are energized when the control k repeats the setting given by the transmitter o.

摘要： 504,536. Control of D.C. motors. RHEINMETALL-BORSIG AKT.-GES., and GIETMANN, A. Sept. 15, 1938, No. 26944. [Class 38 (iii)] Varying E.M.F.-In Ward-Leonard drive, particularly for gun-laying machines, in which the generator D is excited from an exciter C driven by means of a hand wheel B, the exciting circuit of the generator is broken when the generator is at rest by a centrifugal switch d operated by the generator. Thus, if the wheel B is operated while the generator is at rest, no remanent magnetic field is created in the generator, and the driving motor A is not operated when the generator D is started.

摘要： 501,716. Control of D.C. motors. RHEINMETALL - BORSIG AKT. - GES., and GIETMANN, A. July 25, 1938, No. 22020. [Class 38 (iii)] Varying E.M.F.-A system of the Ward- Leonard type, applicable especially to motors effecting adjusting movements of guns, in which the generator is excited by a control exciter operated manually at varying speeds, comprises means varying the field of the control exciter so that the relationship between the exciter voltage and speed is non-linear, and increments of voltage produced by equal increases of speed become greater as the speed increases. The exciter A, Fig. 1, has a field winding a1 of constant energization, and a field a2 energized in accordance with exciter speed from an auxiliary exciter B driven with the exciter A, and having a constant field b. The field b of the exciter B may be energized from a second auxiliary exciter driven with the exciter A and having a constant field. Shunt or series fields may be provided on the exciters to compensate for the resistance voltage drop. In a modification the field al of the exciter A is constantly energized and the field a2 energized by the exciter voltage. In a further modification, Fig. 4, the exciter field a2 is supplied from the exciter B which is driven with the exciter A and has two field windings. One winding bl is constantly energized, and the other b2 is energized from the exciter A. The fields produced by the windings b1, b2 are in opposition and at low speeds the field a2 weakens the field al, while at higher speeds the field a2, reverses and assists the field a1. The relationship between exciter voltage and speed for each of the arrangements described, is explained in the Specification with reference to Figs. 1a, 2a, 3a and 4a (not shown).

摘要： 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 and is connected to the gun barrel by a flexible cord or rope d . The rotary movement of the drum, when the barrel recoils, is transmitted to a rack c by a shaft d , a worm d3, a worm wheel d , a lever d mounted on the spindle d of the worm wheel, and an arm d pivoted to the lever d . This lever engages with a roller c resiliently mounted on the rack C l> and moves the latter from left to right on the recoil of the barrel. On the return movement of the lever d , produced by a torsion spring in the drum d , the lever end d slips past the roller c by pivoting about the pin d . The rack c is connected to a piston c reciprocable in a fluid-filled chamber c of an accumulator c. The chamber c communicates with a reservoir c by passages c , c , the latter being normally closed by a spring-pressed valve c . In operation, on the recoil of the gun barrel, the fluid in the chamber c is forced into the reservoir c through the passages c , c , the valve c having uncovered the passage c . On the disengagement of the lever d from the roller C 2>, the valve c closes the passage c and the piston starts its return movement together with the rack c . The latter sets in motion a train of wheels c , b .. b which operate the fuze-setting mechanism, the wheel c 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 . 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 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.
