Title: Transmission mechanism having an automatic gear change system
IPC: F16H63/30
Filed: 1971-07-01
Abstract: 1361408 Change-speed gear AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 1 July 1971 [30 July 1970] 30811/71 Heading F2D This invention comprises detail structural improvements aimed mainly at reducing the overall length and improving stress conditions in one clutch member in a motor-vehicle automatic transmission of the kind in which two input clutches E1, E2 drive respectively suns P1, P2 of an intermeshed planet train, of which a ring- gear P is fast to a final output member 3 driving a differential gear, whilst brakes F1, F2 act respectively on the planet-carrier and sun P2, a one-way detent R also acting on the planetcarrier. The clutches and brakes are hydraulically engaged under automatic control to provide three speeds and reverse.  Bell-shaped clutch drums. 4, 24 are arranged one inside the other, with their open ends both facing in the same direction. The drum 4 is electron welded to the input shaft 1, and has splined to it internally the discs of the clutch E1, driving the sun P1 through a central shaft 21, and externally the discs of the clutch E2 which drive the sun P1 through the splined cylindrical part of the drum 24, a end-plate 39 secured thereto, and a hollow shaft 42, the end-plate 39 being arranged between the one-way detent R and the clutch-brake assembly. The clutch drum 24 is welded to a sleeve 22 freely mounted on the input shaft 1, and hence the end-plate 39 only is subjected to torsion stress, whilst the frusto-coned bell portion 25 of the drum has to withstand only the stress due to fluid pressure supplied to a chamber 29 from a source 30 to act on a piston 27 to engage the clutch E2. Each portion 25, 39 can thus be best shaped to withstand its individual stress. The end-plate 39 is attached to the drum 24 by splines and a snap-ring, or by welding it to the end disc of the clutch pack. The piston 13 of the inner clutch E1 slides in a sleeve 12 inserted in the splined drum 6. In Fig. 2, not shown, both the outer casing and the clutch drum 24 are stepped to clear an engine starter ring (51), and the end plate 39 is dished to accommodate the end of the inner drum 4, further reducing the overall axial length of the assembly. The arrangement of the centre partition wall 48, one-way detent R, and brake cylinder 49 are as described in Specification 1,347,365. Reference has been directed by the Comptroller to Specification 1,215,669.

Title: Device for filling containers with liquids
IPC: B67C3/30
Filed: 1931-11-06
Abstract: 373,061. Fluid-actuated valves. MARONE, A., Santa Vittoria D'Alba, near Bra, Cuneo, Italy. Nov. 6, 1931, No. 30825. [Class 135.] A device for filling liquid into containers comprises means whereby the filling operation is stopped through a low pressure generated in a closed chamber having a movable wall, as soon as the desired level is reached or is about to be reached. Fig. 1 shows an apparatus filling foamy liquids. The valve 4, connected to a steep-pitched screw 6, is held open against a spring 8 by an arm 10 held by the hooked end 12 of a lever 13 hinged at 14, the other end being attached to the movable wall 16 of a suction chamber 17 which communicates by a hose 20 with the outlet 3. The conical portion 31 of the conduit, which is fitted with a wire jetbreaker 24, centres the stream and prevents it touching the sides of the outlet, thereby preventing suction through the hose 20 until the mouth of the outlet 3 is covered by the liquid. When the outlet is covered the wall 16 is drawn in, the lever 10 is released, and the spring 8 closes the valve. In a modification the liquid streams along the walls of the outlet and produces a continuous suction through an orifice connecting the portion 3<1> with the atmosphere. When this orifice is covered by the liquid, suction takes place through the hose 20 and the valve is closed. The movement of the wall 16 can be utilized also for releasing an acoustic or optic signal.

Abstract: 395,224. Discharge lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 3, 1932, No. 31025. Convention date, Nov. 13, 1931. [Class 39 (i).] A lamp having a negative current voltage characteristic, more particularly having a positive column discharge, is furnished with a grid and is supplied with a current taking periodically the value zero without series resistances, and the circuit is such that the grid voltage becomes negative in or before the period when the discharge current is zero and does not become zero or positive until some time after the moment when the anode potential becomes positive, at which time the anode potential is still increasing. The tube may be supplied with continuous current from a circuit which is periodically broken by an interrupter. The grid is connected to a negative voltage through an interrupter so constructed that at the moment when the discharge current becomes zero the grid has supplied to it a negative voltage this grid remaining negative during a given time. In a modification, as shown in the Figure, the tube is supplied from an alternating voltage 5 which supplies also a circuit including the primary 7 of a transformer, and a resistance 8 and inductance 9 in parallel. The secondary 10 of the transformer is connected through a resistance 11 to the grid 4 which may be a ring sealed to the glass wall. Adjustment of the resistance 8 varies the phase difference between grid and anode voltages and thereby the time of striking of the current in each half-cycle, whereby the average luminosity of the tube is varied.

Title: Improvements in or relating to electric pulse generating apparatus
Inventor: LEVY MAURICE MOISE
IPC: H04J3/04
Filed: 1950-12-22
Abstract: 691,134. Pulse generating circuits. GENERAL ELECTRIC CO., Ltd. Oct. 25, 1951 [Dec. 22, 1950], No. 31261/50. Class 40 (vi). A pulse is generated corresponding to a selected one of a regularly recurring train of pulses by combining the pulse train with a sine wave having the same repetition frequency and a pre-determined phase relationship to it so that the output of the combining circuit comprises a voltage which follows the most negative (or most positive) of the two input voltages at any instant and which is then limited or clipped to produce a pulse corresponding to the pulse it is required.to select. Fig. 4 shows the application to a pulse generator in a 6-channel time division multiplex communication system. A sinusoidal master oscillator 20 which has a frequency equal to the channel recurrence frequency is connected via a phase-shifting network 21 to provide outputs 22-27 which, as shown in curves 11a-11# of Fig. 3, have predetermined phase relationships to one another. An output from oscillator 20 is also applied after zero phase shift to a harmonic generator 29 which generates a sine wave having a frequency equal to the third harmonic of oscillator 20 this is then squared in stage 30 and applied to a phase shifter 31. The outputs from stage 31 are out of phase with each other as shown in curves 12a and 12b of Fig. 3. A sinusoidal output from stage 21 and a pulse train output from stage 31 are mixed in each of the stages 34-39 which may each comprise a pair of diodes as shown in Fig. 1. connected so that the output at terminal 7 (Fig. 1) follows at any instant the more negative of the two inputs applied at 5 and 6. Thus there is applied to mixer 34 a sine wave as shown in curve 11d and a pulse train as shown in curve 12d of Fig. 3 (d) and an output waveform as shown in the heavy dotted curve 13d of Fig. 3 (d) is obtained. The output from mixer 34 is clipped in stage 40 between levels 16 and 17 to produce output pulses 14d (Fig. 3 (d)) which occur in the channel 1 position. Similarly pulses corresponding to the remaining 5 channels are generated in stages 35-40; 36-40, &c. In a modification Fig. 6 (not shown), pulses are generated for a 4-channel system by combining two sine waves and a pulse train, for example in a cathodecoupled valve circuit as shown in Fig. 8. To produce pulses 44, 45 (Fig. 5) occurring at twice the channel recurrence frequency, pulse trains 41 and 42 (Fig. 5) having a repetition frequency twice that of the channel recurrence frequency are mixed with pulses 43 occurring in the position say, of the fifth channel pulse. In a further modification, Fig. 7 (not shown), narrow pulses which are used to leave time spaces between succeeding channel intervals are derived by the mixing of two pulse trains.
