Title: Improvements in jacquard card and verdol paper roll repeater cutting machines
IPC: D03C17/00
Filed: 1937-07-30
Abstract: 496,309. Punching jacquard cards &c. JONES, N. July 30, 1937, No. 21092. [Class 142 (i)] In a cutting-machine for reproducing jacquard cards or verdol paper rolls the master card or roll F is placed between the ends of punch-controlling needles C and a box B carrying spring-pressed detector needles b. When the box B moves from the right to the position shown, those needles b which pass through holes in the card &c. push to the left corresponding needles C which slide in boxes h in stepped blocks H; the end extensions c<1> of needles C thus selected lie athwart the upper ends of certain punches D, so that when a blank card E is raised on a platen L and forced against the lower ends of the punches, holes are cut by the selected (thwarted) punches, the upper ends of unselected punches being pushed by the card into their bores h2. When the platen L is lowered the unselected punches are depressed by engagement of shoulders d<1> thereon with bars J secured to a link J<1> carried by the platen ; similarly the needles C are returned to the right by bars G secured to the box B. The master cards F and blanks E are moved intermittently by cylinders R, R<1> a distance corresponding to one card ; two cards are presented at each station, the punching of any one card being performed in two stages ; this allows of the use of punches of larger diameter than is possible if all the punching is performed in one operation ; as shown the punches are thickened between their ends. Instead of using the extensions c<1>, the ends of the needles C may be enlarged. When the holes in the cards are very close together the steps H can be enlarged to allow room for drilling the bores h ; resilient or bent needles may then be used, which will allow of the ends that enter the holes h being out of alignment with the ends engaged by the needles b. A pinion a drives pinion m fixed on shaft M an eccentric M<1> on which vertically reciprocates platen L. A star wheel and pin connection on shaft M drives, via a sprocket chain, the card cylinders R, R<1>. A cam on shaft M rocks bellcrank lever m<3> to impart horizontal reciprocation to the box B.

Title: Improvements relating to fuel injection nozzles for internal combustion engines
IPC: F02M57/00
Filed: 1943-12-17
Abstract: 570,161. Fuel injectors. C.A.V., Ltd., and NICOLLS, W. E. W. Dec. 17, 1943, No. 21231. [Class 7 (iii)] [Also in Group XXVIII] In an injection nozzle of the kind in which the delivery of the fuel is controlled by a spring-loaded valve of plunger-like form and axially slida,ble in the body of the nozzle, the valve acts as a pump to supply a second liquid to the cylinder or elsewhere. Liquid fuel supplied under pressure to an inlet b traverses a passage h to a chamber g surrounding a shouldered portion of a plunger-like valve f, the outer end of which seats on a conical surface d in the body a of the injection nozzle to close the spraying orifice c until pressure of the fuel on the shoulder lifts the valve against the pressure of a spring i. An axial passage in the valve connects the nozzle, with the hollow interior thereof which is separated from the chamber containing the spring i by a ball valve j. When the plunger valve # lifts, a plug n on its inner end displaces a second liquid from the chamber of the spring i past the ball valve into the cylinder, the return stroke of the valve f under the action of the spring i opening a second ball valve p at, the further end of the spring chamber to admit more of the second liquid thereto. As shown in Fig. 2, the plunger valve f acts through a thrust rod t to displace a plunger w to circulate a second liquid past ball valves p, j in an external system. In a further modification, the underside of the plunger w contacts the second liquid and the valve spring i operates on the forcing stroke.

Abstract: 223,542. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Slepian, J.). Oct. 15, 1923, [Convention date]. Resistance materials. - The resistance of a material containing an oxidizable conducting substance is increased by treating with an oxidizing- agent which is inactive at normal temperatures but active at higher temperatures, and heating the material to oxidize some or all of the conducting substance. The invention is applicable, for example, to the plates forming the resistance element of a lightning-arrester as described in Specification 206,366, which plates consist of a mixture of lampblack, carborundum, and kaolin, moulded and fired. In order to increase their resistance, the plates are placed in a solution of an oxidizing- agent which becomes active at a temperature below that at which the air acts upon the material to be treated and which leaves a non-conducting residue, such as chromic acid, potassium nitrate, ammonium nitrate, barium nitrate, or potassium permanganate. The material is then baked in an oven at about 300‹ C. until all or the required part of the oxidizing-agent has been utilized. Certain portions only of the resistance material, for example the ribs of the discs or plates described in the above-mentioned Specification, may be impregnated with the oxidizing argent.

Title: Improvements in or relating to colour photography
IPC: G03C7/26
Filed: 1921-08-13
Abstract: 193,069. Kelley, W. van D. Aug. 13, 1921, Colour photography.- The invention rediates to the production of additive and subtractive twocolour transparencies. A subtractive transparency is produced in a single silver emulsion on one side of a transparent carrier by printing a first image, for example through the back of the support, developing without fixing, hardening with formalin, and bleaching, as by an aqueous solution of sodium bichromate, of ammonium chrome alum, of copper sulphate, of sulphuric acid, and of potassium bromide in stated proportions, to form a compound on the reduced silver which will fix acid and preferably azo dyes but yet is not affected by the second exposure and development, the fixing bath, certain toning baths or by gelatin dye baths. A second image is then formed in the remaining sensitive silver by printing from the other surface of the emulsion, and is developed and fixed. The first image is then dyed with acid, and preferably azo dyes such as phloxine and orange Y if the image is from a blue-green value negative, or patent blue if from a red value negative. The second image is then toned the appropriate colour, blue-green by the cyanotype iron-ferricyanide process or red by known uranium, copper &c, baths. A fugitive dye such as tartrazin is incorporated in the emulsion to slow down the action of the light for the first exposure, and is washed out before the second exposure, and the sensitive coating may be revived for the second exposure by an aqueous solution of commercial chromic oxide and potassium bromide. The final washing water may be acidulated with acetic acid. An additive transparency is produced by the method of Specification 129,638 by producing with each image a design coloured the same as the image, the two designs being arranged so that a clear portion of the one overlies the design portion of the other as indicated in Figs. 5 and 6. Screen designs as shown in Fig. 7 may be produced by the same bleaching and dyeing process. Through such a screen an emulsion on the other side of the carrier can be exposed to form an additive colour value record. Alternatively, such a screen could also be sensitized on the same side. The bleach described above has the property of repelling certain dyes such as Acid Green L and Ponceau 3 R B, or eosin so that the un@tanned gelatin can be dyed by these to form positives.
