Abstract: 1, 054,084. Light demodulating apparatus. STANDARD TELEPHONES & CABLES Ltd. April 30, 1965 [May 6, 1964], No. 18807/64. Heading G1A. An opto-electric transducer comprises a single crystal body of photo-conductive semi-conductor having at least one flat face, in which an electric field induces the drift of charge carriers between two regions to which a direct current bias potential is applied, and means for coupling to the flat face two optical waves at different angles and co-planar with the electric field, whereby interaction between the waves and the body produces within the surface region a travelling wave pattern between the regions corresponding to a difference frequency of the frequencies contained in the optical waves. The arrangement may be used for the detection of signals modulating a light beam, the light beam being split into two waves and applied at different angles, or the beam being applied with a locally produced beam. Beam splitting may be achieved by a wedge protruding into a part of the beam, or by a pair of prisms with an air gap between part of their otherwise cemented faces. The transducer may be a film of photoconductive semi-conductor such as galliumarsenate on a substrate, the film having two electrodes on opposite faces at one end, and a single electrode at the other, the transverse current developed in the film being coupled out as an electrical output via a tuned circuit or by means of a dielectric body coupled to a waveguide. The transverse field region may be established by forming a diffused-junction in place of the contacts and back-biasing the junction.

Abstract: 1,226,720. Drying by immersion. ALLIED CHEMICAL CORP. 19 Nov., 1969 [10 March, 1969], No. 56727/69. Heading F4G. A method of removing water from a non- absorbent article comprises immersing the damp article into a rectangular water-cooled dewatering sump 2 containing a liquid whose density is greater than that of water and in which water is between 0À1 and 5% by weight soluble, the solvent being maintained at a temperature below its boiling point, whereby the displaced water floats on the solvent surface in the solvent liquid bath, causing the displaced water and accompanying amounts of solvent liquid displaced from the bath to flow over one wall of said sump into an adjacent rectangular water separation sump 4 in which the water and heavier solvent liquid separate into two phases, withdrawing the collected water from the system through an overflow pipe 6 and transferring the collected solvent through a drain pipe 7 to a substantially water-free solvent liquid bath 9 maintaining the solvent in the boiling state, thereby generating a substantially water-free solvent vapour, removing the article from the dewatering sump and exposing it to the solvent vapours, condensing and cycling the solvent vapours through drying means 16 and a reservoir 17 to the dewatering sump at a rate sufficient to replace the solvent liquid displaced from the dewatering sump, and removing the article from the system. The water separating sump 6a (Figs. 3 and 4, not shown) may be U- shaped and surrounding three walls of the dewatering sump such that the initial overflow of solvent and water may take place over three walls of the dewatering sump. Insulating means 11 is provided between the water separating sump 4 and boiling sump to minimize the heat exchange therebetween. The solvent contains between 80 to 99À5% by weight of a waterimmiscible halogenated hydrocarbon component boiling between 20‹ and 100‹ C., and having a density greater than 1À3 gm./cm.<SP>3</SP> at 20‹ C., and at least one non-halogenated organic liquid miscible with the halogenated hydrocarbon component and with water which boils between about 20‹ and 150‹ C. and has a density less than 1À0 gm./cm.<SP>3</SP> at 20‹ C. The water-immiscible component may be between 90 and 98% by weight 1,1,2-trichloro-1,2,2-trifluoroethane or tetrachlorodifluoroethane, and the water-miscible component is methanol, ethanol, n-propanol, acetonitrile, acetone, nitromethane or dioxane.

Abstract: 1,228,794. Ramps. ASSOCIATED CARGO GEAR A.B. 26 April, 1968 [10 May, 1967], No. 19907/68. Headings B8E and B8H. A loading ramp for use in a ship's side has means for maintaining the ramp substantially at a predetermined inclination. As shown, a ramp 1 is hinged to a cross-beam 3 supported by bogies 6 running in vertical guides 4 at the side of an opening in a ship 5. The bogies are driven by an hydraulic motor 8 via chains 10, energization of the motor being controlled by a probe 11 at the free end of the ramp. To avoid possible continuous raising and lowering of the ram, one or more fluid operated rams 15 controlled by a gravity switch permit continuous small adjustment of the ramp's inclination to be made. The ramp includes load supporting rollers 2 and is normally clear of a quay 12 to permit forks &c. of a truck to be moved below the ramp's end. For loading the ship the ramp is inclined towards the ship. When the ramp is not in use the opening in the ship's side may be closed by doors or covers, not shown. In place of the chains, rotatable threaded screws engaging nuts provided at the ends of the beam 3 may be used. Control by probe 11.-Depending whether vertical movement of the ramp causes a contact 25 or 26 to be engaged by the probe, a valve 20 controlled by solenoids 21, 22 causes the motor 8 to be energized, in the appropriate direction of rotation, via conduits 23 or 24. The contacts 25, 26 also control energization of an electric motor 17 which drives a pump 16. Control by gravity switch 39, 40.-The switch causes a ram 15 to be actuated when the angle which the ramp makes to the horizontal varies. If the angle increases a contact 38 is engaged by the switch arm 40, a motor driven pump 28 is energized and the ram 15 is extended due to fluid pressure via a conduit 31. The ramp is accordingly pivoted upwardly from its hinged end. If the angle of inclination decreases, switch contact 37 is engaged, a solenoid 36 controlling a valve 35 is energized and fluid from the ram is released so that the ramp, by its weight and any load on the ramp, will be pivotally lowered. When loading the ship the contacts 37, 38 are repositioned.

A hollow carbon or graphite electrode assembly composed of a plurality of hollow electrode members 1, 2 secured together by hollow nipples 3 has the axial bore therethrough lined with a gas impermeable tube or tubes, e.g. 4, 5, joined together to produce a gas-tight lining. As shown, a dense graphite tube 6 in the nipple 3 protrudes into dense graphite tubes 4, 5 in the electrode members 2, 1, and is a tight fit therein to produce a gas-tight lining. The gastight sealing is improved by the provision of rings 9 of fusible cement, e.g. pitch, with a high carbon content preferably mixed with synthetic resin, e.g. phenol or furan with an admixture of graphite and if required a swelling agent, which when the electrode is used melts and flows into any voids at the junctions 7, 8 and thereafter is carbonized. A gas-tight coating 11 comprising a silicide of a transition metal is preferably provided on the outer surface of members 1, 2 &c. with a ring of fusible cement 10 between the abutting faces. In Fig. 2 (not shown), the lining tubes of the electrode members 1, 2 are a force fit in the lining tube 6 in nipple 3.

The number of high-frequency pulses provided by a generator 1 between the occurrence of a start pulse at 8 and the next stop pulse at 13 is counted at 3 with electronic interlocks to prevent miscounts. When terminal 11 is marked gate 9 is opened to pass the next start pulse from 8 to terminal 6, so reversing bi-stable 5 and opening main gate 2 to pass pulses from 1 to the counter 3. At the same time an output 21 from the bi-stable 5 marks terminal 12 to close the gate 9, and a further output 4 marks terminal 15 to open stop gate 14. The next stop pulse at 13 is therefore applied at 7 to restore bi-stable 5 and stop the count.
