Title: Encodifying graphic information by photography
IPC: H04N1/44
Filed: 1965-05-06
Abstract: 1,096,645. Optical apparatus, electrophotographic processes. RANK XEROX Ltd. May 6, 1965 [May 15, 1964], No.19151/65. Headings G2H and G2J. An original is reproduced, preferably electrophotographically, in scrambled form, by using a fibre optic block, having mutually inclined fibres. In Figs. 1-10 (not shown), an episcopically projected image of an opaque original is received on a block 56 of fibres embedded in clear epoxy resin. A corona discharge electrode (65) and a hopper (81) containing electroscopic powder are arranged above a selenium photo-conductive layer 77 provided on the upper side of the block. A transparent conductive layer 76 has transparent insulating dots 78 covering the light emitting ends of the fibres. The layer 77 does not retain charge in the dark except where it overlies dots 78. Consequently, only these portions remain to be discharged imagewise, by exposure. Cascade development of the resulting electrostatic image is followed by transfer to a final support surface. The transfer may be effected directly under the action of a field from electrode (65) or, alternatively, the developed image may be stuck to the sticky side of adhesive transparent tape which may then be applied to the final support surface. In other forms Figs. 13 and 14 (not shown) the photo-conductive layer, which may be formed on a detachable plate, is spaced from the upper ends of the fibres by a diffusing plate and an air gap. The invention is intended to render a bank customer's signature indecipherable except to officials having the correct decoder.

Title: Improvements relating to the voltage regulation of dynamo electric machines
IPC: H02K19/30
Filed: 1924-08-16
Abstract: 242,368. Railing, A. H., and Huggard, J. P. Aug. 16, 1924. Dynamos, regulating; exciting; regulation of exciting-machines.-The voltage of an alternating-current generator is regulated automatically as the load current varies by employing in the exciter circuit a generator, the permeability of the field magnets of which is varied by the alternator lead current, this generator acting in opposition to another excitation source. The exciter has a divided yoke. or yokes, the limbs of which carry windings traversed by the alternator load current so that an increase of load decreases the permeability and reduces the voltage of the exciter. For a 3-phase alternator, the exciter A, Fig. 1, has, in addition to the ordinary field coils F, three coils on limbs B, B<1>, B<2> in the yoke excited by the alternator load current, or a current proportional thereto, from 3-phase lines m, m<1>, m<2>. For a single phase machine, two yokes and coils are used. The exciter is so connected that the alternator excitation increases with the load current. This may be done by placing the exciter D<1>, Fig. 3, in series with and in opposition to a constant-voltage source E<1> and the field coils of a main exciter G which feeds the alternator field F<3>; or the differential group D<1>, E<1> may feed the coils F<3> directly. Alternatively, the machine D<1> of variable reluctance may directly excite a main exciter which opposes a constant-voltage source in series with the alternator fields. In the arrangement shown in Fig. 5, the variable reluctance machine D<3> opposes a constant-voltage source K in the exciting circuit of a booster H which is in series with a constant voltage source E<3> or the source K and the alternator field coils F<5>. Increase in the alternator load decreases the voltage of the machine D<3> and increases that of the booster H so that the alternator volts are raised. The arrangement may be such that at, say, normal load the voltages at D<3> and K balance and the booster is inoperative, in which case increase and decrease of the alternator load respectively increases and decreases its excitation from normal.

Title: Urea synthesis
IPC: C07C273/04
Filed: 1966-05-03
Abstract: Urea is synthesized from the reaction of ammonia with gaseous carbon dioxide under a pressure of 100 to 300 atmospheres at a temperature of 140 DEG  to 200 DEG C. at a residence time of 5 to 60 minutes which forms a urea melt containing urea, water and ammonium carbamate in a urea synthesis reaction zone and subsequently decomposing said ammonium carbamate in a decomposing and stripping zone, wherein (a) the urea melt from the synthesis reaction zone flows down through said decomposing and stripping zone, (b) most of the heat evolved in the synthesis reaction zone is transferred to the urea melt flowing down through the decomposing and stripping zone, thereby controlling the temperature in said synthesis reaction zone, (c) the urea melt is contacted with a countercurrent stream of gaseous CO2 to cause decomposition of the carbamate and to strip CO2 and NH3 gas released by decomposition of the carbamate, (d) the countercurrent stream of CO2 carrying ammonia and water vapour from the decomposition and stripping zone is passed into the urea synthesis reaction zone wherein the CO2 reacts and consumes ammonia feed to form additional urea melt, and (e) the pressure in the decomposition and stripping zone is maintained at essentially the same pressure as that in the synthesis reaction zone.  The heat transfer (step (b) above) may be effected by employing a liquid (e.g. a hydrocarbon) or a metal or metal alloy which is liquid at the reaction temperature may be used. Suitable forms of apparatus for carrying out the process are described.

Title: Live screens for radiographs giving the impression of relief, and a process for their manufacture
IPC: G03B35/16
Filed: 1946-07-03
Abstract: 633,693. Radiographic line screens. RELIEPHOGRAPHIE, SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. July 3, 1946, No. 19930. Convention date, July 9, 1945. [Class 98 (i)] [Also in Group XL (a)] X-ray line screens having alternate strips opaque and transparent to X-rays for taking radiographs giving the illusion of relief are produced by forming an X-ray transparent base 5, which may be of aluminium, ebonite or transparent plastic material, as by cutting with a tool 15 or by moulding using an engraved matrix die, with the X-ray transparent strips as upstanding ridges 9 and filling in, preferably by electroplating, the channels 8 with X- ray opaque material 6, excess of which is machined off to lay bare the tops of the transparent strips. The screens thus formed are attached to a rigid support 12 at any stage. If the base 5 is shaped by moulding it is attached to the support 12 initially to avoid subsequent deformation of the ridges 9. The cutting tool 15 may be tapered for ease of withdrawal. To provide a sufficient thickness of X-ray opaque material two identical screens may be secured together when placed in register with the help of an X-ray beam. Screens may be formed having the width of the opaque strips a multiple of that of the transparent strips for taking parallax panoramagrams. If a plastic material transparent to light e.g. cellulose acetate is used as the base 5, the same line screens as are used for taking the radiographs may be used for viewing them by transmitted light. The screens may be covered with a layer of varnish to protect them from the air. The Specification as open to inspection under Sect. 91 states also that the screens may be formed by coating an X-ray transparent base, e.g. aluminium with an X-ray opaque material such as lead or a lead salt and cutting through this layer into the top of the base to form X-ray transparent strips. By including in these strips luminescent material such as barium platinocyanide, zinc sulphide and calcium tungstate, non-diffusing intensifying screens may be produced. This subject-matter does not appear in the Specification as accepted.
