Title: Improvements in or relating to driver's brake valves for trains
IPC: B60T15/04
Filed: 1930-08-06
Abstract: 348,969. Fluid-pressure brakes. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, Berlin. Aug. 6, 1930, No. 23569. Convention date, Aug. 30. [Class 103 (i).] A driver's valve device for the simultaneous control of a single-chamber brake on the motor vehicle of a train and two chamber brakes on the trailer vehicles comprises two pressure reducing valves a, b of the kind described in Specification 322,155, [Class 135, Valves &c.], the spindles e, f of which are operated by a pair of interconnected levers g, h pivoted at g<1>, h<1> and a rod i, whereby the braking pressure of all the brakes corresponds to the extent of movement of the operating lever. A return spring l is provided. Each valve, Fig. 2, comprises a diaphragm d subject to the opposing pressure of a spring v and that in a chamber m<1> connected to the brake cylinder by pipe m or n. The compression of the spring is adjustable by the spindle e or f. In the case of the motor vehicle, the valves o, q are normally respectively seated and unseated as shown so that the brake cylinder is open to the atmosphere through openings d<1>, s. When the levers g, h are operated to apply the brakes, the spindle e is raised to seat the valve q and open the valve o so that air is supplied through the pipe c to the brake cylinder until the pressure of the spring v is overcome causing the closing of both valves. The spindle f of the valve b for the trailer brakes is normally raised so that the valve o is open to supply compressed air to the brake cylinders while in applying the brakes the spindle is lowered to open the exhaust valve q. A valve r on the spindle e, f closes the passages s when the spindle is in its highest position to prevent escape of air which may leak past the valve q.

Title: Storage-type electro-optical modulator
IPC: G02F1/05
Filed: 1974-05-28
Abstract: 1470215 Controlling light THOMSON - CSF 28 May 1974 [29 May 1973] 23683/74 Heading G2F [Also in Divisions G5 and H3]  In a known electro-optic modulator wherein selective application of a field between electrodes 11 and 12, or 31 and 32, locally switches a plate 1 of homogeneous material respectively to a first or second stable state, each exhibiting different optical properties towards a "read" light beam from a source 26, the field between electrodes 11 and 12 may be disturbed by the presence of the unselected electrodes 31 and 32 so that switching to the first state is incomplete. It is now proposed to form electrodes 31 and 32 of photoconductive material, CdS, CdSe, ZnS or polyvinyl carbazole, and to render them conductive by illumination only when they are to be selected. In Fig. 2, source 26 acts both as the "read" source and the "illumination" source. Since the requirements for high light-dark conductivity ratio and low optical absorption of the photo-conductor are in conflict for any single optical wavelength, it may be preferable to use different sources e.g. a yellow "read" source 26 and a U-V "illumination" source which is directed to both sides of plate 1, Fig. 4 (not shown). In (Fig. 4), the plate 1 is of PL2T, acting as a <SP>#</SP>/ 4  plate in its first, erased, state and appearing isotropic in its second, written, state. If plane polarized light is incident on plate 1 in its first state, it becomes circularly polarized, is returned to its original polarization by a further <SP>#</SP>/ 4  plate and blocked by an analyzer. With the plate in its second, isotropic state, the further <SP>#</SP>/ 4  plate acts so that the analyzer passes a portion of the "read" light. Reference is also made to bi-stable double refractory liquid crystal materials and to semiconductors which may be vitreous and transparent, or opaque and crystalline. The systems described and claimed comprise a matrix of devices of the sort shown in Fig. 2, with a common plate 1, for use in optical storage systems or displays. For example in Fig. 7 (not shown) data pages presented by the matrix are recorded holographically on photographic film. In the matrix, electrodes 11 and 12 are respective members of a pair of interdigitated combs. Electrodes 31 are individual column electrodes interleaved between the combs, and electrodes 32 are transverse row electrodes, whereby individual matrix elements may be written, for example by scanning. Since unselected elements on a selected row or column may be disturbed to a "half-set" state, it may be preferable to adopt this state as the first, erased, state.

Filed: 1969-05-13
Abstract: 1,263,157. Automatic speed control. SONY CORP. May 13, 1969 [May 13, 1968], No.24365/69. Heading G3R. In a speed control system, e. g. for the capstan of a tape recorder, a signal is generated whose frequency is proportional to the speed and this is converted to a sawtooth wave-form which is used to drive the capstan, means being provided to adjust the slope of the sawtooth so as to set the desired speed. The alternating output of a tachometer generator 1, coupled to the capstan motor M, is squared by an over-driven amplifier Tr 1  and differentiated by C 1 -R 1  the positive (or negative) going pulses rendering a transistor Tr 2  conducting to discharge a capacitor C 4 . Between pulses C 4  charges at a rate dependant upon the value of a speed setting resistance selected by a switch S. The sawtooth voltage across C 4  thus has a period and therefore a peak amplitude dependent on the speed of the motor. The amplitude of the sawtooth is compared first with a voltage E set by a rheostat R 2  and then with the Zener voltage of a diode Z D  and when the amplitude exceeds a set value a transistor Tr 7  is rendered conducting. The voltage at the collector of Tr 7 , which is thus a rectangular wave-form whose pulse width varies with the speed of the motor, is integrated by R 5 -C 2  and the resulting fluctuating D. C. is amplified and used to supply the motor M. The linearity of the sawtooth wave-form is improved by positive feedback using a transistor Tr 3  and capacitor C 3 ; these are omitted from a simplified form of the circuit Fig. 3 (not shown) along with other inessential parts. It is stated that the invention may be applied to controlling a brake acting upon the capstan instead.
