Title: Shell with combined impact and self-destroying fuze
IPC: F42C9/18
Filed: 1945-07-13
Abstract: 602,355. Projectile fuzes. LIPPERT, H.. and BURRI, H. July 131. 1945, No. 18020. [Class 9 (i)] A combined impact and delay action selfdestroying fuze has a firing pin 10 held inoperative against the loading spring 8 of the sleeve 7 in which is is pivotally mounted, by the frictional resistance between inclined faces 14 on the fuze body and shoulders on the centrifugal masses' 12, on the pin. When centrifugal force ceases or on impact due to the momentum of the sleeve 7, this frictional resistance is overcome and the striker fires the detonator 3. Safety centrifugal bolts 21 and a spring 22 normally lock the sleeve 7 until the shell is fired. The pin 10 is made in the form of shears, the legs of which, when centrifugal force has fallen, are forced together to pass up the fixed tube 16. A second stronger spring 20 is normally locked by balls 18 to the tube 16. When a groove 23 in the sleeve 7 moves opposite the balls, on firing movement of the pin and sleeve, the balls are released and allow the second spring 20 to add its force to that of the spring 8. In the modification shown in Fig. 3, the firing pin 24 is pivoted at 28 on a sleeve 27 and engages an inclined face 26 by means of a centrifugal mass 25. The sleeve 27 is locked by balls 37 to a second sleeve 29 on which a weak spring 30 acts. When the pin and sleeves move forward, the balls 37 are released into a groove 31 and the stronger spring 34 and sleeve 27 are released to operate the striker 24. A modification for a nose fuze is similar to the modification shown in Fig. 3, but has only a single spring and impact operates the striker directly.

Title: Means for receiving electric wave communication signals
IPC: H04B1/30
Filed: 1948-07-07
Abstract: 655,773. Radio transmitting and receiving systems. LANUZA, D. July 7, 1948, No. 18213. Convention date, July 9, 1947. [Class 40 (v)] A system for receiving a selected modulated carrier wave to the exclusion of all other signals and noise is based on the symmetry of the desired signal relative to its carrier wave, which symmetry does not exist for any other signal. The modulated carrier wave is supplied in parallel to four modulators M<SP>1</SP> ... M<SP>4</SP> and also to an oscillator L which is synchronized by the carrier frequency. The oscillator L feeds frequency doubling and phase-shifting means D to produce four outputs D<SP>1</SP> ... D<SP>4</SP> at the double frequency and phased 90 degrees apart, which are fed to the respective modulators M<SP>1</SP>... M'. The modulators M<SP>2</SP> ... M<SP>4</SP> are also fed with synchronized carrier from L through a variable gain amplifier A. The outputs from Ml ... M<SP>4</SP> are selected by circuits (not shown) tuned to the carrier wave and are rectified at R<SP>1</SP> ... R<SP>4</SP>, the residual voltage being applied to a unit ch, the output of which controls the gain of amplifier A. The Specification states that the residual voltage from the rectifiers remains zero so long as the amplitude of the carrier frequency fed in from amplifier A follows the envelope of the input carrier signal. Any departure from zero is applied to the unit ch which gives an output voltage which controls the gain of amplifier A in the desired sense. The control voltage from ch thus follows the envelope of the carrier wave and may thus be used as the demodulated signal. A set of assemblies as above may be used to receive the separate channels of a multiplex system using different carrier frequencies even when the side bands of the several channels overlap. The Specification describes a system of transmission for sending a wide band of signal frequencies without requiring a waveband as wide as normal. The signal band is subdivided and the several divisions are separately modulated on to respective carrier waves which are so close that the side bands overlap, giving an effectively narrow total waveband. The result is received as in the above described multiplex arrangement and the outputs of the several channels will combine to give the original wide waveband. Valve circuits for carrying out the system of Fig. 1 are described (Figs. 2, 2b, not shown).

In a load-sharing arrangement for two parallel connected D.C. generators, the voltage regulator for each machine having a potential coil and a coil carrying any circulating current, load current compounding is achieved by passing a part of the load current through the current coils. The generators 1 have voltage coils 4 controlling the field regulating resistor 3, and the load current passes through equalizing resistors 8 to the bus-bars 7, any circulating current passing through the coils 5 which are connected in series by the closed contact 9. Resistors 11 are connected between the midpoint of resistors 8 and the junction of windings 5, and are so proportioned as to divert sufficient of the load current through the windings 5 as to obtain a desired drooping voltage characteristic. Positive compounding may be obtained by crossing the coil connections. If one generator is shut down, the contact 9 is opened by a reverse current relay 10 to disconnect the resistor 11 of the dead machine. In a modification, Fig. 2 (not shown), the single contact 9 is replaced by a pair of contacts, each one operated by the appropriate reverse-current relay. In a further modification, Fig. 3, the main contacts of the reverse-current relays 10 are arranged as two-way contacts which in one position disconnect the generator and via contacts 9<SP>3</SP> and 9<SP>4</SP> respectively, short-circuit the winding 5 via the resistor 12.
