Abstract: 1362042 Fluid-motor control systems J L GRATZMULLER 1 Dec 1971 [10 Dec 1970] 55658/71 Heading F1P An hydraulic, or pneumatic, ram 6 for operating a circuit breaker is controlled by solenoid valves 26, 26' and pressure valves 12, 12' comprising two-position axially-movable members 14, 16, 40, 14', 16', 40', which when occupying the positions illustrated keep the piston 52 at the location shown. To move the piston to the left the valve 26 is actuated to transmit pressure from a supply line 9 to the member 40' and thus vent a space 24'. Consequent upward displacement of the members 14', 16' by a spring 20' shuts off a ram space 48 from the line 9 and connects it to a vent orifice 18'. Simultaneously a previously pressurized line 46 is vented through a check valve 32' and line 36'; and this causes the member 40 to shut an outlet 42 and thus allow pressure in a space 24 to depress the members 14, 16 so as to connect a ram space 50 to the line 9. Actuation of the valve 26' returns the piston to the position shown. Alternatively, the valves 12, 26' and 12', 26 are coupled mechanically or electrically, Figs. 3 to 5 (not shown).. The valves are described in detail with reference to Fig. 2 (not shown).

Filed: 1971-12-08
Abstract: 1367509 Zone-freezing of formed compound PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 Dec 1971 [11 Dec 1970 (2)] 57007/71 Heading B1S Rod-shaped single crystals of semi-conductor compounds are made in a combined reaction and zone-freezing sealed vessel by reacting a volatile component of the compound with a liquid component of the compound in proportions corresponding to the stoichiometric composition of the compound and subsequently contacting the liquid compound and a seed crystal of the compound which prior to the reaction had been placed in the vessel at a level higher than the surface of the liquid and maintained prior to contact at a temperature below the melting point of the liquid, whereby crystallization of the liquid takes place under controlled temperature gradient conditions. The contact is generally effected by slightly tilting the liquid container. If desired prior to the contacting, the seed crystal may be partially dissolved by a local temperature increase. The preferred compounds are III-V compound i.e. compounds which contain an element of group III and an element of group V of the periodic table and in particular gallium arsenide. As shown in the Figure a tubular vessel 1, contained in a furnace 10, contains two boats 4 and 6, which contain respectively volatile component 3 and liquid component 5, and are separated by partition 9 containing a small aperture. Boat 6 which is oblong and corresponds to the shape of the rod desired contains a cavity 7 which contains the seed crystal 8. The furnace contains several controlled heating zones and the temperature spectrum at the bottom of the Figure corresponds to maximum temperatures during the reaction. In particular temperature Ts applies to the whole of zone B, TR to the whole of zone A and this temperature is slightly higher than the melting temperature TF of the compound whilst the seed crystal lies in a temperature gradient between temperature TF and Ts. The crystallization is effected by moving the temperature gradient from the seed crystal in the direction of the liquid in boat 6.

Title: Automatic focusing device for slide projectors

Filed: 1969-11-21
Abstract: 1,235,427. Automatic position control. ERNST LEITZ G.m.b.H. Nov.21, 1969, No. 57133/69. Heading G3R. In a system for automatically adjusting a transparency to a correct focusing position in a slide projector, a cyclically scanned beam of light reflected by the slide produces, in a photo-cell, successive pulses corresponding to the surfaces of the rear cover glass and the transparency, of which the latter only controls a bi-stable circuit and thereby, if necessary, causes operation of a motor to correct the position of the slide. In Fig.3, a slide projector comprises a light source 1, heat shield 2, condenser 3, slide 5 with cover glasses 5a, 5b, and projection lens 6. Light from a source 7 is projected through a slit 9 on to the slide and reflections are scanned by a rotating prism 30 and directed on to a photo-cell 11 which produces pulses corresponding to cover glass and transparency reflections in succession. The first pulse exceeding a predetermined value corresponds to that from the transparency and is effective through a limiting amplifier to set a bi-stable circuit 32-38 which is later re-set by a pulse produced by a generator 31 at a predetermined point in the scanning cycle. Opposite polarity outputs are produced during the set and re-set periods of the bi-stable circuit so that, through a servo-amplifier 20, a reversible motor 21 is operated, by a capacitively derived average signal, in the appropriate direction to ensure that the slide is in a position for correct focus. The accuracy of this position is ensured by initially adjusting the directions of the optical axes of source 7 and photo-cell 11 and, if a mixture of glazed and unglazed slides is to be projected, by the provision of a Schmitt trigger circuit which responds to pulses produced by the front cover glass and slightly modifies the average signal applied to control the motor for glazed slides.
