Title: Electrolytic regeneration of photographic blix solutions
IPC: G03C5/395
Filed: 1975-08-05
Abstract: 1503559 Electrolytic regeneration of photographic solutions FUJI PHOTO FILM CO Ltd 5 Aug 1975 [5 Aug 1974 7 Aug 1974 8 Aug 1974] 32751/75 Heading C7B Used photographic bleach-fix solution originally containing an Fe(III) chelated bleaching agent and an Ag halide solvent is oxidized in an electrolytic cell divided by a porous membrane to convert Fe(II) to Fe(III) while controlling the anode potential within the range -0À10 to 0À50V (relative to a saturated calomel electrode) to prevent decomposition of the Ag halide solvent. The solution either may pass through the anode compartment only, or may traverse from cathode to anode compartment via an opening in the membrane, whereby Ag in the solution is plated out. Anodes of carbon fibre, PbO 2 , Pt or Au are used, at a c.d. # 0À7 A/dm<SP>2</SP>. Cathodes of stainless steel at a potential of -0À2 to -0À7V, a c.d. # 0À01 A/dm<SP>2</SP> and of area less than half that of the anodes are specified. The membrane may be hydrolyzed cellulose acetate, regenerated cellulose, Cu 2 FeCN 6 , agar, a bladder or intestinal wall, asbestos, clay, glass or a synthetic microporous resin e.g. PVC (others listed). If a closed anode compartment is used, a conductive catholyte e.g. IN KNO 3  is required. A cell exemplified has stainless steel perforated cathodes surrounded by a wound PVC membrane on which is wound a C-fibre anode. Nitrogen bubble agitation is used.

Title: Improvements relating to wind screen wipers for vehicles
IPC: B60S1/16
Filed: 1937-11-27
Abstract: 506,506. Windscreen-cleaners. LUCAS, Ltd., J., and PURDEN, R. H. Nov. 27, 1937, No. 32801. [Class 138 (i)] In a windscreen-wiper of the kind in which the spindle c is movable axially in order to disengage it from its driving crank e, and the wiper arm p is pivoted to the spindle and biassed towards the screen b by a spring s, a stop arm is adjustably secured to the spindle so as to hold the wiper q clear of the screen when the spindle is moved to put the wiper out of action. Thus, distortion of the wiper blade when it is inoperative is prevented, and it may be moved to a parked position without fouling the screen framing. The spindle is clutched to the crank e by a spring clutch d, h, i, and carries a pin n co-operative with shoulders o for holding the wiper in parked position. In a modification, the stop is a threaded pin co-operating with a leaf spring on the wiper arm.

Title: Clothes washing machine
IPC: D06F23/04
Filed: 1948-12-22
Abstract: 660,292. Washing- and drying-machines. RAMSEY, A. R. J. (Solar Corporation). Dec. 22, 1948, No. 33077/48. Class 138 (ii). The tub C of a clothes-washing machine which receives liquid and material to be washed and which is spun for drying the material has a recess 28 in its bottom in which sediment is trapped during the washing operation and at least one outlet 32 in its outer wall to discharge the sediment centrifugally when the tub is spun for drying, the outlet being spaced further from the axis of rotation than other parts of the recess wall so that the sediment works from opposite sides towards the outlet by centrifugal action. The tub C is imperforate and the sediment trap 28 in its base is oval shaped and has an overhanging rim 29 to prevent the sediment escaping back into the tub. The trap is covered by the skirt of an oscillating type agitator D to prevent clothing entering the trap. On each side of the trap is a discharge. pipe 32 and these are positioned at the greatest diameter of the trap and extend up the side walls of the tub. In use the tub is stationary during the washing operation while the agitator washes the clothes, any sediment collecting in the trap. When washing is finished the tub is spun to dry the clothes. Water escapes through openings 36 at the top of channels 35 which are formed in the tub wall and centrifugal force drives the sediment out through the pipes 32. A curved perforated baffle 45 is positioned around the tub near the top, this guides clothing downwardly during the drying operation and scum and water passes through the perforations and through the openings 36. The agitator is also perforated to allow scum to pass through it to the sediment trap and so avoid it settling on the clothing. The pipes 32 may be replaced by weighted valves which are opened by centrifugal force and which are closed during the washing period either by their own weight or by a spring.

Abstract: 390,883. Glass manufacture. WOOD, J. T., 21, Duffield Road, Acresfield Road, Pendleton, near Manchester. Dec. 1, 1931, No. 33211. [Class 56.] Relates to apparatus of the kind described in Specification 229,804, [Class 56, Glass], for timing an automatic glass feeder, and consists in replacing the cone pulley and belt, described in the earlier Specification, by shafts driven from a motor by sprocket wheels, and by cams which enable the feeder to deliver different weights of glass in predetermined succession. The apparatus comprises a pair of horizontal shafts 6, 7, as shown in the Figure, journalled in bearings supported by uprights 3 on a table 2. The shaft 6 is driven by an electric motor 11 through a variablespeed gear 12, 13 and an endless chain 16, and the shaft 7 is driven from the shaft 6 by an endless chain 19. A short shaft 33 may extend at right-angles to the shaft 7 and be driven from it through bevel wheels 34, 35. Cams 28, 31 and 29, 30 are secured to the ends of the shafts 6, 7 respectively, and these cams operate valves 23, 27, 24, 26, or electric contact devices. A valve 25 is also operated by a cam on the shaft 33. The valves are of similar construction to those described in Specification 229,804, except that the valve 27 is double-acting. The valves are mounted on cylindrical castings 43 . . 47 which are rotatably mounted in the uprights 3, and can be locked in any desired position. By turning the castings, the timing of the valves can be altered, as described in the earlier Specification. In order that the feeder may be made to deliver charges of different weights in predetermined order, some of the cams may be made with lobes so spaced that the intervals between successive operations of the shears, and also between successive strokes of the feeding-plunger, are unequal. Preferably, the position of the lobes on the cams is adjustable. For example, one of the lobes may be formed on a plate which is bolted to the side of cam and can be secured in any desired position of adjutment. Specification 213,406, [Class 56, Glass], is referred to.

Title: Improvements in or relating to the purification of halide salts obtained from metal halide reduction processes
Inventor: KRCHMA IGNACE JOSEPH
IPC: C01F5/26
Filed: 1953-11-30
Abstract: The impure chloride, bromide or iodide of a reducing metal recovered from the reduction of a metal halide with said reducing metal is purified by treating in the molten state with gaseous chlorine, bromine or iodine, respectively, to form and remove volatile halides of metal impurities in said halide.  The purified halide may if desired be electrolysed to give back the reducing metal and halogen, the latter then being used to halogenate one of the metals having a volatile halide, and the halide reduced to give the desired metal and the impure halide.  Metals which may be thus produced are titanium, zirconium, niobium, molybdenum, tantalum and tungsten, the two first-mentioned being referred to in detail.  Reducing metals referred to are alkali metals (sodium, potassium, lithium), alkaline earth metals (calcium, strontium, barium) and magnesium.  Mixtures of a halide of more than one reducing metal may be used also.  A temperature of 750-1050 DEG  C. is generally applicable in the case of chlorides, e.g. magnesium chloride, the temperature being high enough to ensure sufficient vapour pressure of the volatile halide, but not high enough for attack on the material of the reactor or vaporization of the halide to be purified.  In the examples, electrical heating is used to melt the halide.  The halogen may be preheated.  Halogenation may be effected by passing the halogen into a molten bath of the halide, or by contact as a flowing film, spray or in a packed tower &c., and may be batchwise or continuous. Specifications 479,014, [Group II], and 632,564 are referred to.
