Title: Improvements in or relating to apparatus for producing coloured light effects
IPC: F21S10/02
Filed: 1962-10-24
Abstract: 1,007,257. Illuminated sign. J. E. WINSTANBY. Jan. 24, 1964 [Oct. 24, 1962; Dec. 27, 1963], Nos. 40311/62 and 51051/63. Heading G5C. [Also in Divisions F4, G2 and H2] An illuminated sign comprises a chamber 1 having at least one translucent screen 3 illuminatable by a series of differently coloured electric lamps R<SP>1</SP>, R<SP>2</SP>, B<SP>1</SP>, B<SP>2</SP>, G<SP>1</SP>, G<SP>2</SP>, indepen. dently switched to produce varying coloured effects by their various combinations. The box is painted matt white inside and the lamps are enclosed by a similarly white cylindrical ring 5. Two shades each of red, green, blue lamps are shown. Screen 3 (Figs. 4 ... 7, not shown) bears opaque or coloured translucent symbols, attached by adhesive or sliding in guides, or indicia may be painted or dyed into the screen, either indicia or screen being coloured, or alternatively an opaque stencil possibly having coloured filters over the cutout parts may be placed over the screen 3. Screens 3 and/or coloured filters may be removable and exchangeable. Coloured symbols will change in appearance and visibility as the light is changed in colour. Figs. 14 ... 19 (not shown) illustrate a two-sided device, which may employ fluorescent or neon tubes. Lamps may have coloured bulbs, or normal bulbs in combination with filters may be used. The ring 5 may be replaced by an opalescent sphere. Figs. 8 ... 13 (not shown) illustrate switching arrangements for use with the device. In one case each of the six lamps is controlled by an on/off switch coacting with a cam. Three cams, controlling one lamp of each colour, are driven directly on a common shaft by an electric motor, the other three are mounted on a second shaft, geared to the first via a Maltese-cross device, moving part of a turn for every turn of the first shaft. An alternative arrangement comprises the six lamps controlled by solenoid operated switches, the solenoids each controlled by a photo-cell, and a rotating mask having slots disposed to allow light from a common source to illuminate the photo-cells in desired combination and sequence, to produce a wide range of colours in the sign itself. The switch means may incorporate means for varying the power supplied to each lamp as well as merely switching it, and may be manually operated.

Abstract: A multiple tier bipolar cell of the flowing mercury cathode type comprises an upper positive frame, a lower negative frame, and one or more intermediate bipolar electrodes or frame units placed one on top of the other to form an assembly, each bipolar electrode having an inverted open-box like structure comprising a flat electrically conducting base and insulated side walls, said conducting base constituting the cathode base of one cell unit, said base and insulated side walls forming an enclosure for the next lower cell in the tier, anodes electrically connected to and suspended from the cathode base of the cell unit above it, and in each cell unit a mercury feed box along one end of the cathode base for feeding mercury over it, means for introducing electrolyte and means for withdrawing depleted electrolyte.  As described each cell unit is closely similar to those of Specifications 1,061,443, 1,061,445 and differs from the multiple tier bipolar cell of Specification 1,061,443 in that the tier includes only two cell units and successive cell units are offset from each other so as to allow inspection of the interior of each cell unit.  For this purpose transparent or removal opaque covers are provided over opening at each of the upper and lower ends of the frame units.  The cover plates over the gas collection zone at the upper ends of the units may be of rubber, plastic or easily frangible material, e.g. glass to reduce damage due to formation of explosive chlorine-hydrogen mixtures.  Alternatively for inspection at the lower amalgam outlet lower ends of the cells a rubber or neoprene sleeve is fitted to the cell to permit insertion of a viewing periscope and illuminating system.

Title: Device for the manufacture of moccasins
IPC: A43D25/18
Filed: 1966-09-27
Abstract: 1,121,569. Boots &c. F. PARRI. 27 Sept., 1966 [30 Sept., 1965], No. 42982/66. Heading A3B. Apparatus for making moccasins consists of three components L, M and N which shape the lower portion A, fold the edges of the upper portion B over the edges of the lower portion A and bond them together. The component N consists of a fixed base 6 which resiliently supports, by means of coil springs, a U-shaped frame 7, the space enclosed by the top of the base 6 and the vertical walls of the frame 7 defining the shape of the forepart of the moccasin. The component L consists of a form 3 having the shape of the inside of the moccasin and is movable heightwise by means of a hydraulic ram 34. When a blank A is placed over the component N and the form 3 is lowered by the ram 34 the blank A is shaped and its upper edge is turned outwards by a rim 1 on the form 3 and a sloping surface 8 on the frame 7 as shown in Fig. 12. The blank B having cement applied to its edges is then placed above the form 3 and the component M is lowered by a hydraulic ram 32 to complete the operation. The component M consists of a main member 16 which resiliently supports, by springs 15, a block 19, and a pair of wiper members 17 which are pivoted together and which are guided by pins 18 on the main member 16 which pass through arcuate grooves in the wipers 17. When the component M is lowered the block 19 first contacts the blank B to shape it and an inverted V-shaped groove 14 in the block 19 folds the edge of the blank B as shown in Fig. 12. Further downward movement of the component M causes the pins 18 to engage and depress the frame 7 which in turn rotates bell cranks 10, 12 by means of pins 9. The upper arms 12 of the bell cranks engage wipers 17 to move them inwardly as they descend so that the wipers 17 fold the edges of the blank B as shown in Fig. 13. The wipers 17 also press the edges of the blank B against the edges of blank A to bond them together.

Title: Electrodeposition of refractory metals
Inventor: MELLORS GEOFFREY WHARTON
IPC: C25D3/66
Filed: 1963-11-05
Abstract: In a process for producing dense coherent deposits of Zn, Hf, V, Cb, Ta, Cr, Mo or W, or alloys thereof, the electrolyte consists of an all-fluoride bath free from oxygen-containing compounds, and consists of at least one fluoride of K, Cs, or Rb and a fluoride of another metal higher in the electro-potential series than the metal to be deposited, for example Li or Na, the metal to be deposited also being present as a fluoride or fluoride complex.  The electrolyte composition, temperature, and C.D. are adjusted to obtain dense coherent plates of the metal.  The electrolyte preferably consists of the eutectic mixture 29% LiF, 11/7% NaF and 59% KF.  The metal fluoride, e.g. of Zr, Cb and Ta, should be maintained at a concentration of 5-15%; W or Mo at 3-10%; and V, Cr, Hf at 8-10%. Complexed metal compounds may be used, e.g. potassium hexafluor-zirconate, -molybdate, -vanadate, -columbate, or -chromate. These may be formed in the bath by suspending the metal therein and passing in bubbles of tungsten hexafluoride.  The operating conditions include an inert atmosphere, a C.D. of 5-40 m.a. per cm.2, but up to 200 m.a. in the case of molybdenum and tungsten. Temperature ranges for individual metals are specified and cover about 700-850  DEG C. The cathode on which the metal plates are deposited may be stainless steel, graphite, nickel or copper. The anode may be of the metal to be deposited, e.g. in the form of rondels held in a basket. When a metal fluoride or complex is the main source, it is preferred to use a graphite anode preferably of the type through which hydrogen gas is injected into the electrolyte; or an alloy anode, e.g. of Pb and Na, the latter dissolving in the bath as a component.  Deposits of metal up to 13 mm. thick may be formed and in the form of metal foil, and electro-formed articles may be made.  Reference is made to making ZrB2 by including boron trifluoride in the melt which reacts with KF present to form the fluoborate.  Specification 934,372 is referred to.
