Title: An electro-mechanical control device for a new washing programme for washing machines
IPC: G05B19/02
Filed: 1962-02-15
Abstract: 983,513. Washing machines. CONSTRUCTIONS ELECTRO-MECANIQUES D'AMIENS. Feb. 15,1962 [May 15, 1961], No.5763/62. Heading D1A. A washing machine control device comprises a timer actuated by the setting of a pointer 2 rotatably mounted on a dial, in which the pointer is adapted to be manually set to a selected one of a plurality of predetermined positions on the dial and to rotate towards a final position, in which the washing time is determined by the time of travel of the pointer and the average washing temperature depends on the distance of the selected predetermined position from the final position. Referring to the dial positions in Fig. 1, manual movement of the pointer 2 from position 1 to 2 starts the timer motor and a soaking period 2-5. The timer motor stops on position 6 to allow introduction of washing agents. The pointer 2 is then turned manually to a selected one of the positions 6-39 thus selecting the duration of the washing period which takes place as the pointer 2 is driven by the timer motor from the selected position to position 39. The water heater is on during the washing so that the average washing temperature depends on the duration of the washing cycle, e.g. if the selected initial positions are A, B, C the temperatures are 100‹, 60‹ and 40‹C. respectively. The washing is followed by five rinse cycles R1. . R5, the water being deeper in  the last three (see Fig. 2, not shown). If a manual control switch is operated, the timer motor is switched off at dial position 45 to allow introduction of bleaching agent or drying (no details given).

Title: Improvements in and relating to apparatus for starting and controlling electric discharge devices
IPC: H05B41/232
Filed: 1943-04-14
Abstract: 565,843. Supply and control systems for space discharge devices. BRITISH THOMSON-HOUSTON CO., Ltd. April 14, 1943, Nos. 5964 and 5965. Convention dates, April 21, 1942. [Class 38 (iv)] A pair of electric discharge devices, such as fluorescent lamps 1, 2, are run in series and with circuit arrangements whereby adequate starting voltage is provided for each in turn. A reactive ballast impedance, such as 6, Fig. 1, is connected in series with both, and in shunt with that one which is not connected to the first impedance is connected a reactive circuit 12 having a reactive character different from that of the first impedance. Thus, voltages in opposed phase are initially produced across the discharge device 1 sufficient to start it, and the circuit in shunt to the second device 2 then develops sufficient voltage to start it also. When the supply voltage is not sufficient to run the lamps in series, a transformer, such as 5, is used to step up the supply voltage. When the ballast impedance is inductive, power factor correction may be obtained by a condenser 7 and when capacitive an inductance may be connected across the primary winding of the transformer. An auxiliary transformer winding may inject a voltage of the required phase into the shunt circuit. Two series pairs of lamps may be run in parallel, one part having predominantly capacitive ballast and the other predominantly inductive ballast. Fig. 6 shows a transformer with a secondary winding 33 stepping up the voltage for the series circuit, a magnetic shunt being provided between it and the primary winding 30. The limb 31 has a bridged gap 36 between the winding 33 and a winding 34 adapted to induce a voltage in correct phase in the shunt circuit containing inductive impedance 37, the series circuit containing capacitive impedance 38.

Title: Method of and apparatus for cutting paper and like tubular webs
Inventor: ASHMAN ARTHUR
IPC: B31B23/00
Filed: 1950-03-09
Abstract: 692,149. Cutting apparatus. COLODENSE, Ltd. March 6, 1951. [March 9, 1950] No. 5964/50. Class 31 (i). A guillotine for cutting continuously-moving webs 33 of paper, cellulose film &c. has a straight line cutter 19 operated intermittently to cut the web without interfering with its travel. As applied to making bags, oppositely-opposed cutters 19, 20 are provided for cutting the upper and lower walls 34, 35, Fig. 4, of the web 33 which has been formed into a tube on a mandrel 30 and slotted at intervals along its side walls, removing portions, so that the cutters 19, 20 act to cut the web into sections. The cutters 19, 20, which enter slots 31, 32 in the mandrel 30 during the cutting operation, are carried by beams 17, 18, Fig. 2, connected to the ends of bell-crank levers 11, 12 that pivot on shafts 8. Arms 16 of these levers are coupled by springs, 14 to gears 5, 7 rotatable on the shafts 8 and driven by a gear 3. Latches 22, 23 mounted on pivots 24, 25 and geared together at 26 are urged by a spring 28 into the path of projections 21 on the ends of the levers 11, 12 which are halted thereby with the cutters close to the web. Since the gears 3, 5, 7 continue to rotate, the springs 14 are extended until a cam 29 carried by the gear 7 contacts the lever 11 so as to compress the spring 28 and disengage the levers 11, 12 which then cause the cutters 19, 20 to shear the web as the springs 14 contract. In their contracted position, the springs 14 hold the levers against stops 13 on the gears 5, 7. The Provisional Specification states also that the apparatus can be modified to cut single webs with one cutter only.

Patent GB-382183-A (GB)
Title: Process for the production of double fluorides of aluminium and alkalis
IPC: C01F7/54
Filed: 1932-03-02
Abstract: Alkali-aluminium double fluorides and alkali dichromates or chromic acid are obtained by reacting aluminium salts or hydroxide and hydrofluoric acid with alkali salts of chromic acid, for example, sodium chromate or dichromate.  Other alkali salts such as sodium sulphate or carbonate may also be present.  The reacting solutions should be introduced simultaneously in equivalent quantities into water or the filtrate from a finished charge.  The aluminium salts, for example, the fluoride sulphate or chloride, may be obtained by dissolving aluminium hydroxide in say hydrofluoric acid, or in a previous filtrate, containing say sulphuric acid.  Reference is also made to the use of insoluble aluminium fluoride.  Aluminium fluosulphate solution obtained by dissolving aluminium hydroxide, bauxite, clay, &c., in equivalent quantities of sulphuric and hydrofluoric acids is particularly suitable.  Pure aluminium salts may be replaced by impure salts such as obtained by decomposing bauxite, raw or calcined clay, phonolith, leucite or felspar with say sulphuric, nitric, hydrochloric, hydrofluoric or hydrofluosilicic acid or mixtures thereof, or with mineral acid and flourine compounds such as fluorspar or sodium silicofluoride, provided care be taken that the filtrate obtained from the separation of the double fluoride contains more chromic acid than corresponds to the dichromate, whereby iron is maintained in solution.  The operation should also be conducted without an excess of fluorine or with a slight excess of alumina.  Prior to precipitation, the iron may be oxidized with chlorine or sodium chlorate.  The ferruginous filtrates are neutralized to the dichromate stage, say with mono-chromate liquor, and iron hydroxide is filtered off.  The solution is concentrated to furnish the dichromate.  The double fluoride is purified by boiling with 1 per cent sulphuric acid, and may be dried at 100 DEG  C.  The filtrate from the precipitated double fluoride containing an acid corresponding to the aluminium salt employed may be used for any suitable purpose.
