Patent GB-965792-A (GB)
Title: Transparent electroconductive articles and manufacture thereof
IPC: H01B1/00
Filed: 1961-01-24
Abstract: A method of producing a transparent electroconductive film on a surface of glass or refractory base without previously treating the surface to reduce the alkali metal content thereof comprises heating the surface to a temperature above 400  DEG F. and below the temperature at which the base becomes molten, and applying to the heated surface a composition having a pH between 4,5 and 7,0 and containing an organic tin compound (a long list of suitable compounds is given), an ionizable fluorinecontaining compound, e.g. HF, and an in-organic chlorine-containing compound, e.g. HCl. The surface may be ordinary window or soda-lime-silica glass, borosilicate glass, china, mica, phosphate glass, silicon carbide, tungsten carbide, porcelain or stone.  The articles coated may be windows, cathode ray tubes and space heaters.  In the examples glass sheets are coated by spraying and compared with sheets which have been pretreated by dipping in silicon tetrachloride solution and coated with a solution not containing a fluorine-containing compound.  Other specified components of the solutions are ammonium acetate, glacial acetic acid and n-propyl alcohol.

Title: An improvement in or relating to photographic printing
Inventor: BARBER CLIFFORD
IPC: G03B27/16
Filed: 1968-01-18
Abstract: 1,270,531. Photo-copying. C. BARBER, J. F. FARROW and D. E. CLAFTON. April 18, 1969 [Jan. 18, 1968], No.2761/68. Heading G2A. In a photo-copying apparatus and method, the whole area of the negative to be copied is illuminated, light from the negative falling on photosensitive material 12 which acts as a diffuser, passing light into a recess 54 containing a photocell 56 which controls the exposure time, an exposure being terminated by interposing a filter 58 for actinic light between the negative and the material 12. In this way, the exposure time is dependent on the average density of the negative. Sequence of Operations. The light-sensitive material 12 and the negative strip are fed step by step in unison so that the first negative is beneath the light source. (In a semi-automatic apparatus, the first negative is positioned manually). At this stage, the filter 58 is in the position shown, to allow of focusing without exposure, and paper masks 72 are set for the required aperture size. Depression of a start button starts a motor 66 to raise the filter 58 so that the material 12 is exposed. As stated above, the photo-cell 56 controls the exposure time by association with a condenser which discharges on reaching a pre-set level. This reactuates the motor 66 to lower the filter 58, and operates a motor 38 to advance the paper 12 by a distance equal to the circumference of an O ring carried by a shaft 30. After one rotation of the shaft 30 the motor 38 is stopped by means of a cam 34. A guillotine 52 is provided by an exit slot 50. The apparatus is then ready to copy the next negative.

Title: Process for the manufacture of polyhalogenophthalocyanine pigments
Inventor: FAZACKERLEY ROBERT
IPC: C09B47/10
Filed: 1960-01-26
Abstract: Halogenated phthalocyanine pigments are prepared by treating a stable metal phthalocyanine or an incompletely halogenated derivative thereof with chlorine in the presence of aluminium chloride and at least one mole of an alkali metal bromide for each mole of phthalocyanine.  The products of the process contain bromine atoms and possibly also chlorine atoms and preferably contain 15 to 16 halogen atoms in the phthalocyanine molecule. The invention also comprises copper polybromochlorophthalocyanines having a total halogen content of 15 to 16 halogen atoms per molecule of which about 8 to about 15 are bromine atoms.  The process may be carried out by mixing the powdered phthalocyanine, aluminium chloride (for example 16 to 30 moles per mole of phthalocyanine) and an alkali metal bromide, heating the mixture and passing chlorine through it. The products are dispersed by salt milling, acid pasting, by the process described in Specification 719,072 or by pouring the reaction product into water, adding an organic liquid (e.g. benzene, toluene, xylene and their chloro- and nitroderivatives), filtering, heating the pigment with an organic liquid and finally removing the organic liquid, e.g. by steam distillation.  In examples chlorine is passed into heated liquid mixtures of copper phthalocyanine or a partially chlorinated derivative thereof, sodium or potassium bromide and aluminium chloride.

Title: Improvements in apparatus for aerating liquids
IPC: B01F15/02
Filed: 1924-12-04
Abstract: 249,306. Garrett, P. A. Feb. 4, 1924. Manually-actuated multiple-way valves.-An apparatus for aerating liquids is provided with a liquid-inlet valve, a gas-inlet valve, a snift valve. and a discharge valve operated by cams on a shaft, the liquid-inlet valve being positively closed or allowed to open under the action of springs as required; the aerating-chamber is also provided with a float-actuated air-escape valve. The liquid inlet valve 13 is connected with its spindle through a cushioning-spring 17 and is .closed by a cam 15 acting on a stirrup 16 against springs 14. The snift valve, opened by a cam 23, communicates with a pipe 22 extending to .the top of the areating chamber 1. The discharge outlet is preferably of large size and is controlled by a valve 25 operated bv a cam 26, or the discharge may be made small and the valve dispensed with. Air escapes from the chamber 1 by a valve 32 operated by a bell float 30. The gas-inlet valve 7 is operated by a cam 35, and to give a series of short, sharp openings as described in Specification 202,809 the cam may bear a number of pivoted teeth 26 which open the valve successively in passing in one direction and slide over it in passing in the other. Alternatively the cam may be formed with a groove in which run a number of balls. When the cam is in the position from which it is to be moved to operate the valve the balls run to one end of the groove, which is so shallow that they project from it and operate the valve. When the groove is past the valve the balls run to the other end, which is deep, so that in returning they pass the valve without operating it.

During peak operation power from the turbine 1 is augmented by a gas turbine installation (not shown). At a point 4 feed water may, instead of passing through the de-aerator 10, be diverted to flow through tubes 5b in the heat exchanger 5 serving for the heating of the combustion air 5a used in the boiler through the pipe 7a the desuperheater 7 receives highly superheated steam bled from the turbine. From the desuperheater 7 desuperheated steam passes through the duct 7b to the de-aerator 10 whilst saturated steam passes through the duct 7c from the desuperheater 7 to the fluid heating heat exchanger 8.

Abstract: 100,674. Welffens, E. J., and Renold, Ltd., H. Feb. 28, 1916. Driving-arrangements.-In changespeed gearing for use with spinning and doubling frames &c., and particularly with machines having pairs of tin rollers, a reversible and rotatable frame carries three chain, spur, or positive driving-band wheels geared together, the frame being so securable on the ends of parallel driving and driven shafts that any of the wheels may be attached to either of the shafts, thus giving six alternate speeds. In the form shown in Figs. 1 and 4, three chainwheels a, b, c are carried in bearings in plates l, m, n attached to central plates o by bolts q, p respectively, the plates m, n fitting inclined slots in the plates o. In the position shown, keyways on the wheels b, c are engaged with feathers on the driven and driving shafts e, j, the wheels and frame being secured in position by bolts g, but, by removing the frame and rotating or reversing it, any other of the wheels may be attached to the shafts. Adjustment of the frame parts l, m, n may be made to suit the change of gear and also the distance between the shafts e, f. In the modification shown in Fig. 5, plates t are arranged on either side of the gearing, the wheels a, b, c being carried in bearings w sliding in large slots and adjusted by bolts y in narrow slots x. A light casing v may be bolted to the plates t. Positive driving bands and wheels may be employed. Fig. 11 shows the use of three spur-wheels a, b, c gearing with a cen. tral carrier wheel 15. The wheels a, b, c have their bearing in plates 10, 11, 12, which are adjustably clamped together at the centre by a bolt 13 and plates 14, 17. In this form, one wheel a, b, c is always turning idly, and may be adjusted radially to bring it out of gear. In another form, the wheels may be carried in solid plates, the carrier wheel being clamped in position for engagement with the two active wheels. Slots and guides are provided to ensure correct meshing of the teeth after adjustment.
