Title: Improvements relating to colour photography
IPC: G03C7/30
Filed: 1937-05-13
Abstract: 500,945. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) May 13, 1937, No. 13540. [Class 98 (ii)] In the production of multicolour copies on multilayer photographic material from subtractive multi-colour negatives or positives, the layers of the multilayer copying material are so sensitized that the sensitization maxima coincide or approximately coincide with the absorption maxima of the dyestuffs of the negative or positive which is copied. The copying may be performed with light from which is excluded the spectral region or regions corresponding with the overlapping portions of the absorption zones of the dyestuffs of the negative or positive copied. The filters may comprise dyestuff solutions or coloured gelatine layers, and may comprise several filters for the individual overlapping regions arranged one behind the other. Several dyestuffs may be used in solution or in a layer. A three-layer original has a yellow image produced in the top layer using diethyl-pphenylene diamine as colour developer and pÀundecylaminobenzoylacetanilide -p<1>-carboxylie acid as colour former, a purple image in the middle layer using diethyl-p-phenylenediamine as colour developer and 1-(m-palmitylaminophenyl)-5-pyrazolone-3-carboxylic acid as colour former, and a blue-green image in the bottom layer using diethyl-p-phenylenediamine as colour developer and 2-stearylamino-5- (1-hydroxy-4-sulpho-3-naphthoyl) - aminobenzoic acid as colour former. The copying filter uses a mixture of Crystal Violet and #-naphthoxocarbocyanine. The copying material contains in the middle layer as sensitizer 1:1<1>-diethylbenzthio-# : #<1>-naphthoxy-mesomethylcarbocyanine and in the lower layer the dicyanine dyestuff of formula The colour pictures may be produced in the copying material by colour development, the silver dyestuff bleaching-out process or the anti-diazotate process. Specifications 436,687, 468,400, 466,823, 476,191, 479,838, 483,000, 484,698, 488,853, 489,093, 489,161, 489,164, and 489,274 are referred to.

Title: Improvements in or relating to dispensers for spring retaining rings
IPC: A47F1/08
Filed: 1958-04-30
Abstract: 830,325. Dispenser for retaining rings. WALDES KOH-I-NOOR Inc. April 30, 1958 [June 18, 1957], No. 13717/58. Class 117 Bowed rings R of the type shown in Fig. 3 are stacked on stack rod 20 (Fig. 6) and withdrawn therefrom by hand tool or applicator 32 in the recess 35 thereof, the applicator being thrust horizontally from the left along channel 41 to contact the lowest ring of the stack and to grip it by means of spring 36 for withdrawal to the left. The prongs 14, 15 of each ring cause the lowest and the next lowest rings to stick together, and this difficulty is overcome by the chamfered edge 47 of nose 45 which permits rings R1, R2 to rise (see Fig. 8) whilst ring R is being wtihdrawn, the ring R1 thus disengaging itself from ring R. Chamfer 49 also assists the action but may be replaced by chamfering of the front edge of the applicator. Specifications 746,352, 752,758 and 798,978 are referred to.

Abstract: 754,271. Rubber soles, attaching. DUCKERT, A. J. D., [trading as DANSK GUMMI INDUSTRI]. May 11, 1954, No. 13781/54. Class 17 (2). To increase the effectiveness of the roughening of a rubber sole which is to be adhesively attached to a shoe, the sole has textile fibres embedded in the whole or part of its upper face, a thin coating or sheet of rubber composition containing free textile fibres. Preferably, the fibres are restricted to the toe of the sole and are applied as a thin sheet of rubber material containing 40-50 per cent of fibres. The sheet may be vulcanized or stuck to the sole. Alternatively, the fibres can be applied suspended in a rubber solution, vulcanization being carried out after evaporation of the solvent. Any vegetable, animal or artificial fibres may be used, but waste fibres from spinning or weaving, or fibres from tearing up old fabrics are particularly suitable.

Purifying fatty and mineral oils, paraffin, glycerine, &c.-The pro. cess described in the parent Specification is modified in that during the mechanical separation of the purifying agent from the filter surface the pressure difference which drives the liquid through the filter is wholly or partly removed, or a pressure is applied in the opposite direction. A rotary drum filter 5, Fig. 2, may be used. The mixed liquid and purifying agent pass from the mixer 1 through a conduit 3 and valve 20 to the filter chamber 16. The liquid is drawn through the filter by suction, and the separated purifying agent is removed by a scraper 9 to a chamber 10, from which it is returned to the mixer by a pump 13. The chambers 10, 16, are provided with agitators 11, 17. In the arrangement shown in Fig. 4, the mixer 1 is vertical, and the liquid for treatment is supplied to the chamber 10 where it is mixed with the purifying agent removed from the filter by the scraper, the rrixture passing on through a conduit 25, the mixer 1, and a conduit 3 to the filter chamber 16. Fig. 6 shows an arrangement in which the filter chamber 16 and the chamber 10 are upper compartments of the mixing vessel, separated by a wall 28. A thin layer of fresh purifying agent may be applied to the filter surface by means of a sprayer arranged below the scraper. Specification 172,962 is referred to.

[Also in Division F2] A leak detector for a resilient axially compressible and expansible corrugated tube 1 exposed internally or externally to a medium under pressure connects two members, e.g. pipes 2,3, capable of limited movement relatively to each other, the tube accommodating that movement, and there is a resiliently axially compressible and expansible corrugated tube 4 coaxially surrounding or within the tube 1, the two tubes forming a pressure-tight chamber 7, and a pressure-responsive device, such as a pressure gauge 9, being connected to the chamber for detecting pressure variation therein brought about by leakage in either of the tubes. A pressure of small value such that variations in the chamber's volume and/or the temperature thereof will not affect the pressure in the chamber is established through a pipe 10 provided with a valve 11 so that the gauge 9 is then adapted to indicate leakages in the tube 1 and also the tube 4. Preferably, a vacuum is established in the chamber. The device may be applied to a valve.

Abstract: 1,056,801. Controlling gas supply. SPRITE Ltd. Dec. 7, 1965 [April 2, 1965], No. 14207/65. Heading F2V. [Also in Division G3] A control valve 20 for a gas tap is screwed into the tap body 10 and seated on a jet holder 14 to close a gas inlet 12. A rod 26 is screwed into an axial bore 21 in the holder 14, the bore 14 being tapered towards the valve seating. A ball 22 is held against the rod 26 by a spring 24. The pitch of the thread on valve 20 is such that a turn of the valve through 90 degrees allows uninterrupted flow of gas from inlet 12 around the ball 22 to a burner (not shown). When a further turn of say 70 degrees is made by means of a knob (not shown), the stop 26 is retracted and ball 22 moves sufficiently to restrict the flow of gas. This simmer position may be altered by adjusting the stop 26 in the valve 20. Ball 22 may be replaced by a circular disc or a conical plug fixed to the stop 26, the spring then being omitted. The valve knob is provided with a stop to prevent movement of the valve beyond the simmer position. A safety valve (not shown) may be provided to cut off the gas supply when the flame is inadvertently extinguished, this valve being operated by means of a thermocouple probe situated in the flame and connected to an electromagnet, which releases the valve.
