The apparatus further comprises a housing 10 with a vapour condenser 11 and connected in a circuit with a heater 21 and an additive chamber 22. In use perchlorethylene or other solvent is pumped from a tank 32 into the housing 10 with the laundry and the drum is rotated and the solvent circulated through the heater 21. Valve 40 is opened and the drum spun and the dirty solvent passes into a tank 41 and thence through the still 43 and condenser 44 to the water separator 46. Clean solvent thence returns to the tank 32. The laundry is then rinsed and tumbled in more solvent and spun, the resulting liquid passing into the tank 41. Then water is added to the housing from a tank 52 and circulated through the heater and the rotating drum 14 between a final spin drying water. The temperature required is between the emulsifying temperature and the boiling point of the mixture (60C to 87.7C for perchlorethylene). The resultant emulsion is drained into a tank 61 and a second water separator 66 which preferably has a lower output 67 for solvent than the separator 46 because of the higher proportion of water in its input. The separator (Fig. 2) comprises an inlet 70, a cylindrical coalescer 77 with three layers of successively finer glass fibres, a water outlet 47 and a solvent outlet 48 protected by a water screen 80 which has a hydrolithophobic coating to prevent the passage of water.

Abstract: 1528219 Electronic timepieces DAINI SEIKOSHA KK 11 Oct 1976 [13 Oct 1975 19 Dec 1975 (2)] 42182/76 Heading G3T [Also in Division G5] In an electronic timepiece with a digital LED display, the display is continuously energized. However, to minimize power consumption only one display digit is in an activated state at a time; in addition the energization is controlled in dependence upon the number of segments of a 7-segment display device, which require to be energized to produce a given numeral. The energization is controlled by selectively applying drive pulses of appropriate width, duty ratio or waveform to give substantially the same brightness for all numerals. Persistence of vision gives the effect of continuous illumination. In Fig. 4, an electronic scanning switch circuit 44 couples the BCD coded outputs of secs, mins, hours counter circuits 33 to a de-coder/driver 66, in synchronism with pulse signals corresponding to selected numerals from a numeral selecting signal generating circuit 55 (e.g. a ring counter). The de-coder 66 has seven outputs each corresponding to a respective segment of a 7-segment numeric display 88. The outputs of the numeral selecting circuit 55 are also applied to the display via a signal changing circuit 77 which determines the drive pulse width or duty-cycle or waveform (e.g. a plurality of higher f pulses may be supplied instead of a single lower f pulse having a duration equal to the aggregate period of the plurality of pulses).

Abstract: 1,189,738. Measuring tilt electrically. UNIVERSITY OF QUEENSLAND. Sept. 9, 1968 [Sept. 11, 1967], No.42763/68. Heading G1N. Tilt between two surfaces is measured by a device comprising three legs 13, 14, 15 Figs. & 2 supporting a rigid beam, 10, beneath which are fixed two electrodes, 16, forming a differential capacitor with the surfaces of two mercury pools as a moveable common electrode. The mercury is contained in two cylindrical containers, 17, joined below the liquid surface level by a flexible tube, 21. Another flexible tube 20 joins the two electrode gaps which are filled with an inert gas through valves 25, 26. The supporting legs are shown as fixed but may be made adjustable and are designed so that any movement of either the beam or the surfaces due to temperature changes is accommodated by flexing of the legs, the points of support remaining fixed Capacitance changes are measured by a ratio transformer bridge supplied from an audio frequency oscillator, the bridge being manually balanced to a detector hull reading for greatest accuracy of measurement. Alternatively an arbitrary bridge ratio is chosen and the unbalance signal is recorded being fed through preamplifier, amplifier, synchronous detector and low-pass filter to a recorder. To maintain the electrode gap constant with temperature two embodiments are described. In the first Fig. 3, (not shown) the vessels are sealed to the beam by a resilient, insulating material e.g. silicone rubber while the expansion of the mercury (174) and the silica pillars (28) supporting the vessels from base plates 18 is matched by that of stainless steel spacers 19. The second embodiment Fig. 4, (not shown) employs resilient blocks (29) between the base plates and the vessels, which are spaced from the beam by silica pillars (30) these being of a length required to balance the expansion of silica blocks (31) immersed in the mercury. In this way errors of less than 4À10<SP>-10</SP> radial per degree C. may be achieved.

Abstract: 1481623 Photographic silver halide material for making photomasks FUJI PHOTO FILM CO Ltd 9 Oct 1974 [9 Oct 1973] 43846/74 Heading G2C A photographic light-sensitive material for making a photomask comprises a transparent support having coated thereon a masking layer which is (i) 0À05 to 3 microns thick, (ii) etchable by ion-etching or chemical etching, (iii) opaque at least to ultraviolet radiation and (iv) made of a metal e.g. chromium, tellurium, a metal alloy, a metal oxide e.g. ferric oxide, silicon, germanium, silicon dioxide, germanium dioxide, or a chalcogen glass compound of arsenic, sulphur and germanium, arsenic, selenium and germanium or germanium and sulphur, and a layer of a light-sensitive silver halide photographic emulsion coated on the masking layer. There may be one or more subbing layers between the emulsion layer and the masking layer. Photomasks may be prepared by exposing the material to a light-image, processing to form a silver or silver halide image, ion-etching to remove the emulsion binder from areas other than the silver or silver halide image areas to expose the masking layer, removing the uncovered masking layer in these areas from the support by ionetching or chemical etching and then removing the remaining emulsion binder in the silver or silver halide image areas. In order to improve the resistance of the silver image areas to ion-etching by hardening the binder, the silver image may be tan-bleached followed by fixing or re-development, and possibly further tan-bleaching, or baking. An alternative processing method for forming a photomask involves exposure to a light-image, removal of image or non-image areas by a method other than ion-etching to expose the masking layer and then ion-etching the masking layer in uncovered areas. Methods for removing image or non-image areas in the alternative method include (i) development and etch-bleaching, (ii) development, tan-bleaching and washing with warm water to remove unhardened areas and (iii) tanning- development and washing with warm water.
