Abstract: 1494918 Hardening photographic layers KONISHIROKU PHOTO INDUSTRY CO Ltd 11 Feb 1975 [13 Feb 1974] 5707/75 Heading G2C [Also in Division C3] Gelatine is hardened by treating it with the combination of a compound having at least one carbo-di-imide group in the molecule and a compound having at least two vinylsulphonyl groups in the molecule. The combination can be contained in a gelatine-containing liquid capable of forming a photographic layer of a light-sensitive silver halide photographic material or can be incorporated into a processing liquid which is brought into contact with a gelatine-containing layer of an exposed silver halide photographic material. Suitable vinylsulphonyl compounds include those in which one - SO 2  - group is bonded to two vinyl groups. The gelatine can be an acylated, guanidylated, carbamylated, cyanoethylated or esterified derivative. The hardener can be incorporated in the sub layer or in an emulsion layer, interlayer, protective layer or backing layer.

Abstract: 1415052 Moulding closure caps CONTINENTAL CAN CO Inc 8 Feb 1973 [11 Feb 1972] 6133/73 Heading B5A [Also in Division B8] A metal closure is initially manufactured as a one piece blank 10<SP>1</SP>, Fig. 2. This is further formed by conventional means into the closure 10, Fig. 3, which has knurled rings 14, .15, tamperproof slots 16, a radiused portion 25 and a transition portion 26. A glob of suitable compound is inserted on to the end panel 11 and formed into a liner 28 by application of a moulding punch 30 which centres and seals on the transition portion 26. The liner is formed so that the projecting portion 34 will receive the surface 37 of the bottle 18. When the closure is applied an upper closing tool 40 engages the radiused portion 25 and by downward movement reforms it to conform with the bottle profile surfaces 37 and 38, Fig. 4. At the same time the liner 28 is deformed so that the portion 32 seals the neck 20 and the portion 34 is wiped around the surface 38 to complete the seal. The remainder of the closure is applied by a rolling tool so as to conform with threads 21 and/or other retaining means 1311. In a modified version the moulding punch (56), Fig. 5 (not shown), is of a different configuration resulting in the liner having a different initial relationship with the bottle neck (20), Fig. 6 (not shown).

Title: Discharge recording

Filed: 1972-02-09
Abstract: 1386863 Discharge recording blank FUJI PHOTO FILM CO LTD 9 Feb 1972 [9 Feb 1971] 6163/72 Heading D2B [Also in Division B6] A discharge recording blank comprises a paper substrate having a conductive surface and a coating of finely-divided unbound powder on the conductive surface. The conductive surface may be formed by coating the paper with a layer comprising conductive carbon black. The powder may be white e.g. titanium dioxide, zinc oxide, zinc sulphide, lithopone, antimony trioxide, white lead, polystyrene, polyethylene, phenolic resin, maleic acid resin, or coloured e.g. red lead, iron oxide, or other coloured inorganic or organic pigment. The powder may be applied to the conductive surface using glass beads and a cascade technique, or by rubbing or dusting,- or by an electrodeposition coating method. Recording is made by passage of an electric current between two electrodes, one in contact with the powder coating and the other with the conductive surface. This causes removal of powder to form the desired image. If necessary, the blank may be used again, by removing residual powder and recoating either with the same or a different coloured powder. Alternatively, the residual powder may be transferred to paper. If a powder fusible by heat or soluble in a solvent is used,- residual powder may be fixed to the recording blank or to the transfer paper. Transfer of residual powder may be effected by means of a corona discharge.

In a directional condenser microphone having at least one diaphragm exposed to a sound field on both sides and a phase-shifting element placed between one side of the diaphragm and the sound field, the diaphragm has an area of at least 10 cm. and one of the sides, or the diameter, of the diaphragm is much larger than the wavelength in air of the highest frequency to be transmitted. The microphone has a uni-directional pattern that is essentially frequency independent although it has a high self-capacity (10<SP>2</SP>-10<SP>3</SP> pF.) and consequently may be connected to an associated amplifier by long cables (10 metres), a bidirectional pattern can be obtained by the addition of a frictional acoustic resistance between the diaphragm and an electrode: it is also suitable for use as a loud-speaker. A perforated plastic trough 3 (Fig. 3) is placed on a sheet-like acoustic frictional resistance 2, e.g. filter paper, contained in a perforated sheetmetal casing 1. The diaphragm 7 which has been vapour-coated with a metal is tensioned by an adhesive connection at its rim to an electrode 5, being separated therefrom by parallel threads 6 consisting for example of 20 microns thick, beads made of the synthetic filamentary material known under the Registered Trade Mark " Perlon." A perforated cover 8, Sa acts as a housing for the instrument. Fig. 4 shows a vertical cross-section of the assembled microphone, the cavity 13 and the resistance 2 performing the phase-shifting for the frequencies below 2 kc/s. which impinge on the back of the diaphragm after traversing the sides of the microphone. Two diaphragms, only one of which need be electrically effective (Fig. 5, not shown) and having the frictional resistance between them can be used to produce a different directional pattern, or a mechanically-operated perforated slide (Fig. 8, not shown) could be used. A slack, thin, resilient diaphragm (Fig. 7, not shown), may be provided to protect the instrument from moisture. An assembly of two diaphragms each with its own electrode, having the acoustic resistance between the electrodes (Figs. 5 and 9, not shown) may be used for stereophonic recording. The diaphragm may have any shape, e.g. circular, oval or brickshaped, as in Fig. 16 (not shown). Alternatively the microphone may be shaped like a hexagonal pencil (Fig. 18, not shown); a perforated hexagonal sleeve acts as the electrode, while a diaphragm covers, although it is separated from, three sides of the sleeve, an acoustic resistance lining the remaining three sides.

Class 75(2) The front glass of a vehicle lamp having a light source disposed in the transverse vertical plane containing the focus of a parabolic reflector, consists of two prisms one above the other to produce a downward deflection of the light beam, the dividing line between the prisms being on the horizontal diameter of the lamp and each prism having a series of spaced vertical flutes increasing in depth and width from top to bottom. The prisms may have an angle of 2 to 5 degrees. The dividing line may be masked by a transverse bar supporting an opaque shield covering the upper front half of the lamp bulb. Plane areas are provided between the flutes in the upper half to produce a long range beam. For use as a fog lamp, the spacing between the flutes may be reduced so that adjacent flutes touch the bottom. Additional tapered flutes may be provided between the main flutes in the upper half of the glass. The light source may be a lamp having two transverse filaments, that of lower wattage being disposed slightly above the axis of the reflector. Either or both filaments can be used at one time.
