Filed: 1931-04-14
Abstract: 372,913. Spray carburetters. CARBURATORI MEMINI SOC. ANON. ITALIANA, 16, Via Poliziano, Milan, Italy. April 14, 1931, No. 11088. Convention date, April 14, 1930. [Class i (iii).] In a carburetter for an aircraft engine, separate fuel-supply pipes are provided for the atomizing jet and for the float chamber, and automatic means cut the fuel supply off from the float chamber when the aircraft is inverted, and lead it directly to the atomizing jet. During normal flying, fuel from a tank 26 passes through pipes 30, 10 into the float chamber 5, which is open to the atmosphere at 15, and is fed to the fuel nozzle 4 through a passage 19. When the aircraft is inverted, the pipe 30 is uncovered and a weighted valve 16 prevents the fuel in the float chamber from escaping into the atmosphere. The fuel is then fed by passages 31, 25 past a weighted automatic valve 23 and a restricted orifice 21 to the passage 19 and nozzle 4. The Specification as open to inspection under Sect. 91 (3) (a) also describes a carburetter in which the fuel is fed through passages 9a, 35 to a chamber 37 in which is a valve 23a which, according to the position of the aircraft, closes either the entrance of fuel into a duct 10a leading to the float-chamber 5a, or the entrance of fuel into a duct 19a from which it falls directly into a duct 42 leading to the nozzle 4a. A needle valve may control the supply of fuel in the latter case, and air may be added to the fuel through the needle valve. This subject-matter does not appear in the Specification as accepted.

Title: Method and arrangement for synchronizing alternating voltages
IPC: H04N5/067
Filed: 1943-07-12
Abstract: 577,019. Radio receiving circuits. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. July 12, 1943, No. 11291. Convention date, July 11, 1942. [Class 40 (v)] [Also in Group XXXV] The voltage e2 of an alternating current generator G, Fig. 1, which may be of high or low frequency and of sinusoidal, saw tooth, or impulse form, is synchronized with a voltage e1 by a control voltage v0 determining the frequency and phase of the generator voltage and which is obtained by crossmodulation of the voltages e1, e2 and which varies in magnitude and sign in accordance with the relative frequencies and phases of these voltages. The control voltage comprises two components, the first of which is proportional to the frequency difference, whilst the second, which effects final synchronism as regards phase operates only after the first has reduced the frequency difference to zero. The voltages e1, e2 are mixed in modulators M1, M2, a 90 degrees phase shift being introduced into the voltage e2 supplied to the modulator M2 by the network R1, C1, and the phase-displaced difference frequency output voltages u1, u2 of the modulators are combined in a further modulator M3 to provide the control voltage v0, an integrating circuit R2, C2, rotating the phase of the voltage u1 to an extent proportional to the difference frequency and providing that component of v0 which produces frequency synchronism. This component vanishes when the frequencies of e1 and e2 are equal and is replaced by the second control component for synchronizing the phases of e1, e2 and which is proponent of these voltages. The motors may be arranged on a common shaft, or may be replaced by a single torque motor of the twophase asynchronous type having in its rotor a magnet which causes the rotor finally to assume a position in which the magnet lies in the line of the resultant magnetic field of the currents in the two-phase windings. In a modified form of electric control, correcting voltages from batteries are switched to the generator by a rotating field relay operated by the " difference frequency " and a polarized relay actuated by the unidirectional component of the voltages u1, u2. The circuit of Fig. 1 may be used for homodyne radio reception, the received modulated signal supplying the voltage e1 and the generator G the local carrier e2. Demodulated signals are available at terminals 2 or 3, according as to whether the transmitter is amplitude or phase modulated. For the reception of suppressed carrier transmissions, the network R1, C1 produces a phase shift of 90/n degrees and frequency multipliers increase by n times the frequency of the voltages u1, u2 applied to the modulator M3. The circuit of Fig. 5 may be used in a television receiver, a sawtooth scanning voltage e2 of the generator G being synchronized by an impulse voltage e1.

[Class 60] A screw-thread grinding-machine comprises means to support and rotate a workpiece and to move it axially during grinding, one or two rapidly-rotating, multi-grooved grinding wheel, each with a cam to feed it to the work and withdraw it after a single axial movement of the workpiece which is thereby finished. The grinding wheels f, which have peripheries grooved to correspond to the desired pitch of thread, are adjusted, to correspond to the desired spacing of the threaded portions on the work, by capstans 10, gearing 12, 14 and screws 16, Fig. 5, engaging nuts 17 in slides s which are thus each adjusted axially on shafts w, 91, 97, Fig. 3, and clamped by a screw 94. Each slide s carries, by its arm 101 and threaded sleeve 98, a gauge i and bar r on which slides a member o which carries the grinding-wheel head 34 adjustable for lead angle, by a crank 43, Fig. 1, gearing 41 and shaft 39, about a pin x. Each member o can be adjusted, for wear of the wheel f, on the bars r, Fig. 3, to and from the work, by a handle 23, gearing 28, 29, Fig. 1, pinion 32 engaging a rack 33 on a sleeve q normally fixed, relative to the slide s, by a rack t and a lever v with teeth w. The gauges i, Fig. 1, are advanced to engage each in a groove of the corresponding wheel f, lateral adjustment being effected by rotating the sleeve 98. They are then returned, a work piece is inserted between the heads b, c and the gauges advanced to engage it, lateral adjustment of each gauge and corresponding wheel f being effected by its capstan 19. The gauges are then swung out of the way as shown in Fig. 2. Two motors, p, Fig. 1 are then switched on to drive the wheels f and a motor 47 to drive a shaft 55, Fig. 5, slowly and, at a still slower speed, a screwed sleeve 72, Fig. 4, and a work-driving dog b<SP>1</SP>. The shaft 55 has a cam 56 which switches off the current after one revolution and cams j, k which, acting through levers v, Fig. 2, rack t, and sleeve q, advance the wheels f to engage the work. The hand operated rack and pinion 33, 32 serves to adjust this advance. The screwed sleeve 72 engages a normally fixed nut 73 to move the slide 82, carrying the head and tail stocks, to the right while the dog b<SP>1</SP> rotates the work to produce the desired spiral feed. The cams k then allow springs x to withdraw the wheel f and the cam 56 switches off the current. After removal of the work the slide s is returned to the right by rotating the nut 73 by a handwheel 74. If taper work is to be ground a support 88 of the slide 82 is swivelled about the shaft 59 and secured by clamps 89. If the work has not pre-cut threads the gauges are not used. Specification 527,829 is referred to.
