Abstract: 1,181,052. Tin oxide coatings. TOKYO SHIBAURA ELECTRIC CO. Ltd. 22 Jan., 1968 [25 Jan., 1967], No. 3232/68. Heading B2K. Tin oxide coatings on a substrate are produced by applying an organic stannous compound selected from the group consisting of stannous alkoxide Sn(OR) 2  and stannous carboxylate Sn(OOCR) 2  wherein divalent tin is bonded to an alkyl radical R by the aid of oxygen on the surface of the substrate and pyrolysing the applied coating. The organic stannous compound may be applied in the form of a solution in an organic solvent of low water content the applied coating dried at 100 to 250 Centigrade to obtain a transparent film manifesting interference colours, and the coating further heated to 300 to 400 Centigrade. The coating may be further heated to a temperature of more than 500 Centigrade to increase its mechanical strength and surface resistivity. The tin oxide coatings can be used as transparent films, electro-conductive films or prime coatings for chemical platings. The tin oxide coatings may be formed on selected portions only of the substrates. In the Examples: 1), 2) a soda lime glass substrate and a fused silica plate are coated with a transparent tin oxide coating having interference colours; 3) a rod of alumina ceramic is coated with a transparent tin oxide coating; 4) a porous Mullite ceramic rod is coated with tin oxide and silver paste applied to opposite ends of the rod to form electrodes; 5) a mixture comprising a solution of stannous caproate in hexanol and a solution comprising cellulose acetate in amyl acetate was brushed onto the surface of a borosilicate glass plate and dried at 150 Centigrade and then heated at 650 Centigrade to obtain the transparent tin oxide coating.

Title: New colouration process
IPC: D06P3/66
Filed: 1962-01-29
Abstract: Half-tone effects are obtained in a process in which a reactive dyestuff or a multiplicity of reactive dyestuffs are applied to a cellulose textile fabric in conjunction with an acid-binding agent and a portion only of the dye so applied is allowed to react with the fabric thereafter a printing paste containing a substance which will prevent further reaction between fabric and dye is applied locally to one surface of the fabric and then the fabric is heated to effect reaction between the dyestuff and the remaining portions of the fabric.  The reactive dyestuff may be applied together with the acid-binding agent by slop-or nip-padding or by printing or the acid-binding agent may be applied prior to the dyestuff.  Known adjuvents and thickeners may be coemployed.  If a number of reactive dyes are used one may be more reactive than the remainder.  As substances preventing further reaction there may be used substances which neutralize the acid-binding agent e.g. acids and acid salts such as oxalic acid, ammonium oxalate, ammonium sulphate, ammonium dihydrogenphosphate and zinc sulphate or substances which react with the dye faster than cellulose does, e.g. triethanolamine, sarcosine, ethylenediamine, hexamine, phenylhydrazine and p-phenylene-diamine. After application of the print paste, the fabric is preferably dried with hot air at 50-100 DEG C. and then baked at 120-150 DEG C. or steamed at 100-105 DEG C.  Examples of dyeing cotton fabrics are given.

Title: Automatic multipolar toggle lever electric switch
IPC: H01H73/50
Filed: 1928-02-03
Abstract: 284,716. Leyhausen, W. Feb. 4, 1927, [Convention date]. Automatic circuit-breakers &c. - Relates to automatic multipolar switches of the kind in which, when one phase opens (for instance, on overload) the remaining phases are opened, and the invention consists in arranging the acceleration pressures due to the opening of one switch effecting the opening of the remaining switches. The arms 1, to which are connected bell crank levers that are to be released on overload, are mounted on shafts 2 - - 4 which are coupled by sleeves 5, Fig. 4, in such a way that a certain movement by one shaft is made before the other is moved. This is effected by a pin 8 in the shaft 3 bearing against one or other wall of a recess 7 in the sleeve 5. Each arm 1 carries a pin 10 all of which are engaged by a pivoted yoke 12 which is raised by a pin 20 for simultaneous closure of the switches, the pin 20 being engaged by an arm 19 connected with the operating handle 15. After closure, the yoke 12 returns under spring action and arms 18, 19 mounted on the shaft 17 of the handle 15 rotate backwards until a ratchet 6 engages a pawl 26. When one switch opens on overload, the shaft is carried by its spring 11 and carries, due to its kinetic energy, the other shafts. The pin 10 of the arm first released strikes the yoke 12 and by means of the pin 20 depresses the pawl 26 to allow the handle to be restored. Another pivoted yoke 21 is, during closure, rotated by the yoke 12 to tension the spring 23, thus holding the armatures 24 of the release magnets 25 harder against their stops 27 and preventing a momentary overload from opening the switches. The Specification also refers to no-volt release and to opening the switches manually with the handle 15.

Filed: 1924-02-13
Abstract: 235,259. Elmendorf, A. Feb. 13, 1924, Bending. -- Fibre boards, particularly for boxes, are bent at right-angles by gripping them between two clamps spaced apart from each other and mounted for swinging movement relatively to each other so that during the swinging movement the clamp members or the inner side of the board approach each other at their inner edges but, during such movement the space between the inner edges of the other clamp members, measured along the outer sur. face of the board, is not increased ; the boards may be bent a number of times to make the zone containing the bend flexible. As shown the clamps consist of opposed jaw members 1, 2 and 3, 4 spaced apart and connected on one side of the board A bv a short non-extensible flexible strip 6, preferably of spring steel; when the clamps are swung from the position shown in Fig 5 to that shown in Fig. 8, the board is bent but the distance along the outer or convex side of the board is not increased and so the fibres of the board are not subjected to tension. To prevent any splitting or bulging in the inner side of the bend, the board may be bent over a member 7 fitting between the inner edges of the jaw members 1, 3. The clamps may be actuated by links 33 operated from a reciprocating crosshead and connected to levers 22, 23 fixed to shafts 10 journaled in blocks 9 on the lower jaw members 1, 3 and having eccentric portions 11 bearing on the upper jaw members. The clamps are supported from a frame by strong springs 15 connected to channel members 12 fixed to the upper jaw members 2, 4 and pins 13 arranged in the channels of the members 12 are engaged by projections 14 on the blocks 9. The springs normally hold the clamps against abutments 18 which have a concave configuration at their lower edges and engage blocks 21 carried by the upper jaw members and as the levers 22, 23 are actuated, the jaw members are clamped on the work and then rotated so that their outer edges swing downwards and inwards towards each other; stops 24 prevent the upper jaw members striking each other as the springs return the clamps to the normal position. Catches 25 may be provided to engage the clamps and prevent any swinging movement thereof until the clamping operation is completed when they are raised sufficiently to release the clamps.

Title: Improvements in the degreasing of metals and like non-absorbent materials
IPC: C23G5/02
Filed: 1941-03-24
Abstract: 548,116. Degreasing metal and like articles. COSWAY, R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 24,1941, No. 3943. [Class 91] Metal and like non-absorbent articles are brought to a dry and degreased condition by immersing them in a bath of a volatile grease solvent maintained in a superheated condition. This treatment may comprise the drying step following the degreasing treatment with a solvent or its vapour; or it may itself constitute the degreasing treatment, the cold article immersed therein causing the vapour primarily to condense on its surface and effect the degreasing before its temperature reaches that of the superheated vapour when the condensate will have re-vaporized. A solvent having a vapour heavier than air is preferred, such as trichlorethylene or perchlorethylene, and the vapour is maintained at a temperature of 10‹-50‹C. above its boiling point. Suitable apparatus for carrying out the single treatment of the articles comprises an open-topped chamber having the superheated vapour zone in its lower part, the upper part communicating freely therewith and being provided at its upper perimeter with a cooling coil to set an upper limit to the vapour zone and with means to collect the condensate from the coil. One form of the apparatus for carrying out the two-stage treatment of the articles comprises a tank 1 sub-divided at its lower part into a vapour degreasing compartment 2 and a drying compartment 3 each of which is provided with a heater 9, 17, operatively connected to thermostats 10, 16, respectively. The compartment 3 is provided with an oil jacket 11 and insulation 12; its bottom wall 13 is serrated to promote circulation of the vapour beneath the articles placed thereon and its sides are extended upwardly into the tank at 18 to form a trough 19 exterior thereto for discharging condensate into the degreasing compartment 2. The tank is provided with a cooling coil 4 and trough 5 as described in .the single-stage apparatus, the condensate from the trough being also if desired discharged into the compartment 2. The articles to be cleaned are lifted from compartment 2 and lowered into compartment 3 without raising them above the coil 4. In variations of the apparatus, the degreasing may be effected in a number of successive compartments one at least of which is preferably a vapour degreasing compartment. Continuous operation may be provided by passing the articles on a moving belt through the various compartments.
