[Also in Group XXXVI] Video signals are supplied to an electroluminescent solid state display device by means of non linear capacitors in the form of a single layer, the elemental circuits being provided by arrays of elemental and strip electrodes. In the embodiment shown in Fig. 3 the electroluminescent layer 24 is located between a transparent electrode 22 and elemental electrode 26 each of which is in contact with a conducting pillar 30 in an insulating layer 28. Each of the pillars 30 is in contact with elemental electrodes 34 which, together with parallel strip electrodes 36, are printed on the surface of a layer 32 of a non linear dielectric whose other surface bears elemental contacts 38 registering with both the electrodes 34, 36. The video signal is applied to contacts 38 and the power source is connected across electrodes 36 and 22 giving the equivalent elemental circuit shown in Fig. 4 with two non linear capacitors 23, 25 in series with each electroluminescent element 21. In the embodiment shown in Fig. 6 the non linear dielectric layer 56 has parallel strip electrodes 64 on one surface, the pillars 30 are in contact with elemental electrodes 58 and these are connected to the parallel strip electrodes 60 by means of diode rectifiers 62. The video signals are applied to strips 60 and the equivalent circuit is shown in Fig. 7. In a third embodiment, Fig. 9, the elemental electrodes 74 in contact with the pillars 30 are connected resistively to further electrodes 78 in turn connected via diodes 76 to parallel strip electrodes 72 and the other side of the non linear dielectric 71 has strip electrodes 84 registering with the electrodes 78 and further parallel strip electrodes 86, 88 registering with the electrodes 74 to provide the equivalent elemental circuit shown in Fig. 10. The electroluminescent layer may be of zinc sulphide, copper and manganese or copper activated and may comprise phosphor particles embedded in glass or ceramic. The non linear dielectric may be of ferroelectric material e.g. barium or barium-strontium titanate, barium stannate, or sodium or potassium columbate or tantalate and its electrodes may be silver.

Abstract: 1399596 Hydraulic reciprocating motors MACTAGGART SCOTT & CO Ltd and R C RUSSELL 6 June 1972 [12 June 1971] 27618/71 Heading F1A In an hydraulic motor comprising a rotary hub 10 splined to a shaft 20 and having radial pistons 11 over which cylinders 12 slide, a hollow cylindrically stepped distributor valve member 31 is capable of limited axial movement in a housing port 30, fluid pressure in annual chambers 5 1a, 52a, 53a, 54a acting on the valve member to urge it against the end face of the hub 10. For full torque operation two of the annular chambers e.g. 52a, 54a are connected to a supply of pressure fluid and the other two (e.g. 51a, 53a) to exhaust. Passages 55, 56, 57, 58 in the valve member 31 connect the annular chambers to axial passages 19 in the hub 10. Then as the hub rotates each axial passage 19 alternately receives fluid from and exhausts fluid to the valve passages 55-58. The consequential reciprocation of the cylinders 12 causes rotation of the hub due to the cooperation of rollers 16 on the cylinders with multi-lobed cam tracks fixed between housing ports 23, 25, 26. Half torque operation can be obtained by providing a valve, Fig.4 (not shown) which is operable to connect one annular chamber to supply and a second to exhaust, the remaining annular chambers being inter-connected, whereby fluid leaving a cylinder previously charged with high pressure fluid from the one annular chamber flows via the valve and the inter-connected annular chambers back into and out of a cylinder before exhausting through the second annular chamber. A brake wheel 69 is splined to the shaft 20 and carries plates 70 disposed between plates 71 fixed to a housing port 67. Springs 73 force, via a member 72, the plates 70, 71 into contact, the force of the springs being overcome by supplying fluid to a chamber 74 thereby to move the member 72 away from the plates. In a second embodiment, Fig.1 (not shown) the valve member 31 has only two annular chambers.

Abstract: 992,577. Heating webs in fluidized beds; drying webs. BRITISH PAPER & BOARD INDUSTRY RESEARCH ASSOCIATION. Aug. 11, 1961 [Aug. 11, 1960 (2)], Nos. 27894/60 and 27895/60. Headings F4G and F4U. Undried or incompletely dried webs of paper, board or cellulosic pulp are dried by passing them substantially vertically through a fluidized bed of solid particles in a container having two streams of gas, e.g. air or superheated steam, flowing upwards at different speeds so that in an inner zone next to the web the particles move upwards, and in an outer zone away from the web they move downwards, baffles to deflect the upwards stream of particles towards the web and heaters in the downwards streams. As shown, the web 2 passes vertically upwards through the container 1. Primary air streams are admitted by the slots 5 and secondary air streams through the porous or perforated false bottom 6. Tubes 8 are heated internally, e.g. by steam or by electric elements. Baffles 10 divide the container into inner and outer zones, and have projections 12 opposite one another on their inner faces. Adjustable shutters 13 allow the gap between the baffles and the false bottom to be varied. The apparatus contains particles, e.g. small glass balls or rounded-grain sand, which are fluidized by the air streams. The primary air stream is faster than the secondary, so that the particles are carried upwards in the central zone and fall downwards in the outer zones. This apparatus may be used in series with another like apparatus, or with conventional steam-heated drying cylinders.

Abstract: 1,271,056. Rolling mills. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 9 June, 1970 [9 June, 1969], No. 27999/70. Heading B3M. The crown of a pair of work rolls in a roll stand is determined by plotting a calibration curve for the stand, the curve being derived from a number of flexure curves each corresponding to the substitution of a pair of rolls of known crown in the stand or in an identical stand. Fig. 1 illustrates a typical flexure curve drawn for rolls having a known degree of crown, the curve being obtained by pressing together the rolls under different pressures P. The section of the curve between P o  and P m  (which may represent 50 and 500 tons respectively) is mainly dependent on roll crown and is approximately parabolic. This section can be expressed by P=p 1 S +p 2 S<SP>2</SP>, where p 1  and p 2  are coefficients and S is the variation in screwdown position from that existing at pressure P o . The value of p 1  for each flexure curve can then be determined, and these values plotted against roll crown to provide the desired calibration curve. The calibration curve can be used to determine the crown of a pair of work rolls whose crown is not known by finding a value of p 1  for the rolls from an appropriate flexure curve and reading off the value of crown against this value of p 1  on the calibration curve.

Title: Improvements in or relating to a method of applying a rendering of cementitious material to structures

Abstract: 616,907. Plastering. CHEECOL PROCESSES, Ltd., AEROCEM, Ltd., (formerly M. & E. SPRAYING, Ltd.), and MOLLO, E. Sept. 19, 1946, Nos. 28142 and 37548. [Class 20(iv)] A method of applying a rendering of a plaster-like material to the surface of a structure comprises forming a plaster mix, adding a wetting, frothing or dispersing agent thereto in an amount of from 0.001 to 0.5 per cent by weight of the settable solid component of said mix, to form a mass of creamy consistency, i.e. sufficiently fluid to pass through a pipe line and spraygun, yet sufficiently self-supporting to remain in position on the surface, introducing air into the mass to effect an increase in volume of at least 20 per cent, preferably about 50 per cent, and discharging the aerated mix on to the surface by an air-pressure operated spray-gun or like spraying device. The preferred wetting agents are the sulphated higher alcohols or their alkali metal salts. According to one example of the process, to a mixture of 96 lbs. of coarse sand, 36 lbs. of hydrated lime and 4 gallons of water, was added 25 fluid ounces of a wetting agent consisting of sodium salts of the sulphated higher fatty alcohols. The mixture was whisked for 4 minutes and could then be readily sprayed to form a good even rendering on a wall surface. The rendering may be made cellular, thus giving it thermal and sound insulating properties.
