A method of producing a visible image in a plurality of colours on a recording element comprising a particulate photoconductor dispersed in a resinous binder coated on a paper backing comprises the steps of producing on the coated surface of said recording element a pattern consisting of electrostatically charged areas and of substantially reduced charge areas in substantial configuration with one colour of said visible image; applying to said pattern a mixture comprising electroscopic particles of said one colour dispersed in an insulating liquid to develop on said coated surface an image of said particles of said one colour; mechanically removing excess insulating liquid from said surface leaving thereon only a thin film of said liquid; and, with said thin film on said surface, repeating the aforesaid steps at least once to produce an image of electroscopic particles of another of said plurality of colours on said coated surface. The particulate photoconductor may comprise zinc oxide, and the process may comprise for example the steps of exposing a precharged photo-conductive sheet to light from a colour transparency with the yellow light removed, developing the resultant electrostatic image with a developer comprising a dispersion of a yellow pigment in, for example, dimethyl polysiloxane fluid, removing excess developer by means of draining, squeegeeing, or with mangle rollers, and repeating the charging, exposure and developing processes for magenta and cyan or other colours. The sheet may be heated finally to help fix the images. As an alternative to the pigment dispersions mentioned above, the developer may also comprise dispersions of coloured resins - preferably thermoplastic resins of styrene or terpenehaving suitable dyes or pigments incorporated therein.

Title: A method and means for controlling the depth of electrolytic engraving
IPC: C25F3/02
Filed: 1947-04-11
Abstract: 631,756. Electrolytic etching. CROSSLAND, J. A., and CROSSLAND, E. M., (trading as LOCKETT, CROSSLAND, & CO.). April 11, 1947, No. 9739. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 21, 1947.] [Class 41] A method of controlling the depth of engraving in an electrolytic engraving bath comprises restraining a current-interrupting device by means which is subjected to an electrolytic action, the same as or proportional to that which effects the engraving, and which is such as to become inoperative and thereby release the current-interrupting means when the desired depth of electrolytic action has taken place. As shown, a metal strip B, supported in a bath K, is under tension. by means of a spring R which is connected to a blade L. During engraving of a plate C the blade L connects two contacts P, A in the electrolytic circuit. The depth of engraving is controlled by the strip B which is eventually reduced in size, so that it is broken by the tension of the spring R. The contacts A, P are then disconnected so that the circuit of the plate C is broken. Contacts G, H are then connected, whereby a circuit is complete to actuate an electric bell S. The invention is applicable also in the case where the article to be engraved is a rotating printing roller, only part of which is immersed in the bath at a time, the control member being also similarly mounted and rotated.

Title: Improvements in or relating to transducers
Inventor: CHAIMOWICZ ADAM
IPC: H03H9/125
Filed: 1956-03-29
Abstract: 823,549. Ultrasonic delay lines. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Feb. 27, 1957 [March 29, 1956], No. 9882/56. Class 40 (8). The length of the magnetostrictive input or output element of an ultrasonic delay line is less than the effective electrical length of the associated coil. The latter is defined as the length of a perfect coil in which the field does not extend beyond the ends of the coil and which would produce the same effect as the actual coil. The effective electrical length exceeds.the actual length by at least 40%. The invention is based upon the consideration that, in a conventional delay line, the minimum duration of the stress-wave pulse, and hence the maximum operating frequency, depends upon the length of the coil. Reduction of the coil length below the value necessary to produce 1 Ásec. pulses is impracticable. By using a thin slice of magnetostrictive material 9, Fig. 2, incorporated in a delay line 10, 11 of non-magnetostrictive material, the pulse duration becomes a function of the thickness of the slice and is substantially independent of the length of the coil 7, whereby the previous limitation is removed. The slice 9 may be made of nickel and may be silver-soldered to a copper or brass delay line 10, 11. Alternatively, the delay line may comprise a liquid, e.g. mercury, contained in a non- magnetic tube. In order to reduce eddy-current losses, both the magnetostrictive portion and the other portions of the delay line may consist of bundles of wire bonded together with a non- conducting resin. The non-magnetostrictive portion of the delay line may be made of a material having a specified property, i.e. a low temperature-velocity coefficient. In order to increase the power input, a number of coils 18, Fig. 5, may be distributed along the line 17 and linked by delay units 19 which provide the same amount of delay as the sections of line between the coils. In all cases the output transducers may be identical to the input transducers.

Cooking-stoves; airheating fittings; heat radiators; boilers, arrangement of; air supply.-A multiple-story building has a group of central vertical flues, which, together with stoves, hot-water apparatus, hot closets, and the like form the heating - apparatus of the building. Fig. 2a shows part of a group of three equidistant flues 1 in the midst of which is arranged a cooking-stove comprising a boiler 10, an oven 16, and a grate with a hot-plate 13. The spaces between the flues 1 are enclosed by vertical curved plates 10, 20 and by horizontal plates 17 at the floor and mantelpiece levels. Between the mantelpieces and the ceilings these plates 17, 20 form hot clasets, to which doors are fitted. Between the mantelpieces and the floors the plates 17, 8 form the casing enclosing the stove. Each of the flues 1 is, as regards that pait of its length which is below a diaphragm 5, an air supply flue; above this it is a smoke flue. The air rising through the pipe 1 passes through an aperture 6 into the space below the boiler 10; part passes through apertures 9 in the plates 8 to the rooms and part passes to the fire-place of the stove. The combustion products circulate over the boiler 10 and around the oven 16, and thence through an aperture 7 into the upper part of the flue 1. Soot collects on the diaphragm 5 and may be removed through a doorway 18. The edges of the plate 17 above the range form the mantelshelves. The tubes 1 are preferably ribbed or fluted.

Title: Improvements in the thermal cracking of liquid hydrocarbons
IPC: F02B3/06
Filed: 1958-03-28
Abstract: A process for cracking liquid hydrocarbons to produce acetylene in which the heat necessary for the cracking is produced in the hydrocarbons by burning a part of the hydrocarbons with oxygen or an oxygen containing gas comprises supplying the gas to a cracking space above the surface of the liquid and so directing the liquid on to the surface that a part of the liquid situated at the surface is burnt by the flame formed by ignition.  In a preferred embodiment a diesel oil having boiling limits of 200-325 DEG  C. is maintained in a reaction vessel 1 at a desired level by means of a level indicator 3.  Oxygen is supplied through a nozzle 2 which is at a distance of 4 cms. above the surface of the liquid and is caused to ignite in the space above the liquid hydrocarbon by means of a small methane-oxygen auxiliary burner (not shown). Cracked gas leaves the reaction chamber at 126 DEG  C. and passes to a condensing system in which the hydrocarbons, steam and carbon black are separated and the condensed hydrocarbons are returned to the reaction vessel <PICT:0824622/IV (b)/1> through a pipe 5.  About 30% of the carbon black remains in the reaction vessel and this is removed by constantly withdrawing a portion of the oil through pipe 6.  Additional diesel oil is added through a pipe 7. The cracked gas contains 5.8% of acetylene, 8.5% of olefines and 5.9% of saturated hydrocarbons.  Steam or nitrogen may also be added to the oxygen.  Specification 804,595 is referred to.
