Title: Method of producing an electroconductive article
IPC: C03C17/25
Filed: 1951-07-31
Abstract: <PICT:0704793/III/1> <PICT:0704793/III/2> <PICT:0704793/III/3> <PICT:0704793/III/4> In a method of applying a transparent electroconductive film to a base by spraying a metal compound on a hot base, a spray of non-uniform density is applied to the hot base and the spraying is discontinued after a continuous film has been formed but before a maximum amount of film has been formed on all portions of the base.  A glass panel (Fig. 1) has bus bars 13, comprising a highly conductive metal powder, such as gold or silver, mixed with a vitrifying binder which fuses to the glass when heated. The panel is heated to above 400 DEG F. but below the fusion point of the glass, which forms a firm bond between the bus bars and the glass, and while the panel is still hot it is conveyed past a spray, consisting of a tin halide and a reducing agent, which forms a conducting film 14.  The spray pattern is as shown in Fig. 4, and the plate is passed at such a rate that a non-uniform coating is applied, i.e. the resistance is greater at B, E and H than at A, D, G or C, F, I (Fig. 1).  In a modification for a panel where the bus bars 24 are not parallel (Fig. 5), a spray having a pattern as in Fig. 6 is used so that the film is most dense where the bus bars are farthest apart. Specification 632,227, [Group XI], is referred to.

Abstract: 1,264,036. Speed governors. CATERPILLAR TRACTOR CO. April 9, 1969 [June 12, 1968], No.18203/69. Heading G3B. A governor for use on C.I. engines in trucks where a foot accelerator pedal is used, is loaded by a high speed spring 44, a low speed spring 40, and an intermediate spring 50 which is effective upon adjustment from the top of the low speed range toward a higher speed to oppose rapid acceleration of the truck. The governor controls the position of a fuel pump rack 20 and when the engine is started, spring 40 is slightly compressed. To increase speed, lever 32 is rotated counterclockwise to move collar 34, spring seat 46, and sleeve 48 to further compress spring 40. At the upper limit of the low speed range the sleeve 48 abuts spring seat 38 so that the spring 40 no longer functions and the spring 50 takes over. Further movement of the lever 32 compresses spring 50 until its stiffness equals that of the spring 44 where upon both springs act to oppose outward movement of flyweights 14 in the normal manner.

Title: Improvements in or relating to photographic films having a lenticular grating
IPC: G03C7/46
Filed: 1952-07-18
Abstract: 716,529. Lenticular film for photographic use. CIBA Ltd. July 18, 1952 [July 19, 1951], No. 18266/52. Drawings to Specification. Class 98(2) A cellulose ester film with a lenticular grating on one side is surface hydrolysed and also provided with a layer as of gelatin or polyvinyl alcohol on the other side. Such gelatin layer may have a lenticular grating which optically corresponds to the first mentioned grating. An intermediate layer of hardened gelatin may lie between the hydrolysed surface and the lenticular gelatin layer. In preparation the first lenticular grating may be produced by embossing, or casting of the film using a lenticular surface as mould, the hydrolysed layer formed by application of aqueous alcoholic alkali to the non-lenticular side and the gelatin layer or layers applied thereover, with bichromate sensitization of the outermostgelatin layer and production of lenticulations therein by exposure through the first lenticular 'grating and washing as described in Specification 682,853. The The film, still not sensitized for image production, and whether it has a grating on one side only or on both sides, may now be sensitized by application of an acid solution containing a complex ferric salt and a silver salt, and, desirably, also a dyestuff to restrain the action of exposing light as described in Specification 701,529. Exposure and development of such film by the method of Specification 701,529 provides the unexpected result that picture formation is confined completely or to a great extent to the hydrolysed layer, and definition is improved by reason of the small thickness of such layer. The intermediate layer of hardened gelatin referred to above is present for the purpose of restricting penetration of the bichromate sensitizer, used for production of the second lenticular layer, into the hydrolysed layer. An aqueous solution containing ferric ammonium citrate, silver nitrate, citric acid. the monoazo dyestuff from diazotized 1-amino-benzene-4-sulphonic acid and 1-phenyl-3-methyl-5-pyrazolone-2':5'-disulphonic acid, and a wetting agent is exemplified as sensitizer for image production.

Title: Method and apparatus for discharging aqueous solutions of carbon dioxide
IPC: B67D1/14
Filed: 1934-06-21
Abstract: 422,830. Discharging carbonated liquids. BROWN, M. J., 140, 57th Street, Niagara Falls, New York, U.S.A. June 21, 1934, No. 18378. Convention date, June 21, 1933. [Class 14 (i)] In the discharge of carbonated liquids such as carbonated beverages, beer, &c. with concomitant reduction of pressure, the period of over saturation is prolonged by discharging the liquid in a thin film through an orifice, and simultaneously directing this film so as to establish non-turbulent contact with a braking surface of high smoothness, substantially parallel to the direction of flow, until the velocity of the liquid is substantially reduced, the construction of the apparatus being such that eddies, spray, sharp angular impact with the braking surface, and sharp changes of direction in the liquid flow are obviated. The reduction of pressure is also made complete in one very restricted part of the apparatus, and as nearly instantaneous as possible. In one form of the invention incorporated in a standard soda water siphon faucet, 20 is the carbonated liquid conduit leading to a rotary valve 21 operated by a handle 22 adapted to be connected to either a port 23 or a port 27. The port 23 leads by way of passages 24, 25 to the usual needle orifice 26. The port 27 leads through a passage 28, an annular passage 29, and four or more holes 31 to an orifice chamber 33. The actual orifice at which the reduction of pressure and, in the form shown, contact with the braking surface 40 occurs, is formed between the horizontal portion of the latter surface and the upper part of a cylindrical member 38 threaded on to a hollow rod 34 which ends in the needle jet 26. A set nut 37 is provided by means of which the dimensions of the annular orifice may be adjusted. Other embodiments are also described, in one of which the annular orifice is separated from the braking surface on which it impinges at a slight angle by a short air gap, and in another of which the braking surface is arranged with its axis horizontal. Paraboloidal, ellipsoidal, and conical braking surfaces can be employed in place of the preferred flattened spheroidal form which is shown.

Abstract: 571,617. Sewing-machines. AKTIEBOLAGET R. NYSTROM & CO. Nov. 5, 1943, No. 18412. Convention date, Nov. 10, 1942. [Class 112] In order to stop a sewing-machine at the end of an operation, with the needle out of engagement with the work ; after the driving power has been disconnected a manuallyactuated device is operated to rotate the driving shaft into a predetermined position. The needle or needles will either complete a singlethread or multi-thread stitch not completed when the power was disconnected, or the needles will disengage from the work. A blind-stitch sewing-machine, such as used for the invisible stitching of padding collars and lapels, has a curved needle 1 which is oscillated by a shaft 2 and coacts with a looper 3 to sew work located on a support 4, which is lowered by the depression of a pedal 5. A toothed wheel 7 on the shaft 2 is in mesh with a toothed wheel 9 on a shaft 8, the wheel 9 being integral with a ratchet-wheel 10. When the pedal 5 is depressed, a chain 14 is pulled, turns a wheel 11 and a feed hook 15, meshing with a tooth on the wheel 10, turns the latter to the required position. At a further depression of 5, the support 4 is lowered. After reinsertion of the work, the pedal 5 is released, and a spring 13 turns the wheel 11 back to its initial position, whereby the hook 15 is brought out of engagement with the wheel 10 by means of a member 16 and prevents the pulley 11 continuing to turn in the direction of the spring force. A separate pedal connects, or disconnects, the driving power to the shaft 2.
