Abstract: 321,642. Hanby, W. Aug. 3, 1928. Divided on 321,638. Annealing. - Metal goods such as sheets, wires, or strips are annealed and pickled in a receptacle 1 containing a combined pickling and annealing bath as described in Specifications 321,638 and 321,643, being fed through the bath by spaced sinuous guides A<1>, B' and A<2>, B<2>. The goods &c. are fed between guides A, B to rollers C and pass between guides A<1>, B' to the rollers D which feed them on between the guides A<2>, B<2> to rollers E. The goods then pass between guides A<3>, B<3> to rollers C and are fed through a washing bath 2 in similar manner from whence they are fed by rollers F into a coating bath 3. The guides are mounted so as to be adjustable laterally and the rollers are carried in bearing members provided with slotted bars which are connected for adjustment purposes to the guides. The lower of the rollers D may be mounted so as to contact with a brush mounted in supports on the bottom of the receptacle 1. The bath in the receptacle 1 may also be composed of 80 per cent of sodium chloride, 5 per cent of sodium cyanide, and 15 per cent of sodium carbonate. The goods passing from the receptacle 1 to the bath 2 may be cooled and dried by a blast of air or reducing gas.

Title: Photo-planographic printing formes
IPC: G03F7/06
Filed: 1959-11-05
Abstract: 883,846. Planographic printing formes. AGFA A.G. Nov. 5, 1959 [Nov. 7, 1958], No. 37601/59. Class 98(2). The silver halide diffusion transfer process is effected to transfer a soluble silver complex to a colloid layer and the latter is treated with, an organic mercapto compound to make a' hydrophobic silver derivative and then with greasy ink for the printing. The process thus avoids the requirement for nuclei in the receiving layer and avoids also intermediate oxidation and washing processes as described in Specification 847,436. In Example 1 a wet strength paper sheet is coated successively with a specified gelatine-barium chloride composition and then with one comprising hypo or sodium sulphate with alkali and formalin, dried, developed in contact with an exposed negative using hypo in the developer if none is present on the sheet, and treated with an alkaline solution of N<SP>1</SP>-(N<SP>3</SP>-octadecylsemicarbazide) - dithiocarboxylic methyl ester. Further examples replace the latter substance with sodium dodecylxanthogenate, hydrazinedithiocarbonic acid, octadecyl ester, 2- mercapto-5-dodecylmercapto - 1,3,4-thiodiazole, 2-mercapto-4-heptadecyl-thiazole, 1 - amino-2- mercapto-5-heptadecyl-1,3,4-triazole and 1- octyl-2-mercapto-benzimidazole. Other such compounds are indicated. Specification 883,843 also is referred to.

Title: Photographic camera with automatic exposure setting
IPC: C08B3/20
Filed: 1958-12-01
Abstract: 854,608. Photo-electric control devices. GAUTHIER G.m.b.H., A. Dec. 1, 1958 [Jan. 25, 1958], No. 38593/58. Class 40(3). In the automatic exposure setting device of a photographic camera, an exposure setting member is adjusted by a D.C. motor, the direction of rotation of which is determined by the alternative operation of two electronic amplifiers, preferably transistors, in dependence on the position of the displaceable contact of a moving coil relay responsive to the output of a photoelectric element exposed to ambient light. In Fig. 3, the output of a photo-cell 9, which may be amplified at 19, determines the state of a moving coil relay 8 whose displaceable contact 7 may be, as shown, in a central open position, or may contact one of two fixed contacts 10, 11, to earth the base of one of two transistors 12, 13, thus initiating a collector current in the transistor. A low-power, high speed, D.C. motor- 6 is driven in a direction dependent on which transistor is conducting, and operates through reduction gearing 23 and a friction clutch 32, to adjust a diaphragm setting ring 5 and also to move the wiper 15 of a logarithmically stepped resistor 14 which shunts the relay 8; alternatively, this resistor may be in series with the relay. The motor runs until the relay current is such that contact 7 moves to the open position; if the diaphragm setting ring 5 is driven against one of its stops, warning and locking signals are given, and a cut-out switch in each transistor circuit may operate. The resistor 14 is connected to an exposure time setting ring 4 so that account may be taken of the time setting; this connection may be by means of a detachable coupling such that relative adjustment may be made between resistor and time setting ring to allow for other exposure factors, e.g. filters, film sensitivity. Alternatively, the ring 5 and the wiper 15 may be made relatively adjustable. In addition, the fixed contacts 10, 11 of the relay 8 are mounted on an adjustable carrier 18 to provide for further adjustment. Temperature compensation is provided by a temperature-sensitive resistor 20 and a variable resistor 41 in the relay circuit. The motor and gearing are accommodated in the inner space of the lens shutter. The photo-cell and relay are located in the upper part of the camera, the carrier 18 being adjustable by an external knob; and the amplifier components are housed, separately or in combination, in free spaces in the cover hood. The adjustable exposure setting member may vary exposure time or exposure value instead of the diaphragm setting.

Title: Improvements in and relating to the production of tubular woven fabrics
IPC: D03D37/00
Filed: 1930-12-24
Abstract: 360,731. Tubular fabrics; circular looms. ETABLISSEMENTS ROTATISS, 14, Rue Frederick Lemaitre, Paris. Dec. 24, 1930, No. 38927. Convention date, Dec. 26, 1929. [Classes 142 (ii) and 142 (iv).] A tubular fabric for covering electric wires &c. has spiral warp and weft threads 41, 126, Fig. 8, making different angles with the axis of the tube, which may have a large number of threads 41 and a small number of threads 126 or vice versa. The fabric is woven on a circular loom which is somewhat as described in Specification 307,400, [Class 142 (iv), Woven fabrics &c.], but modified so that the warp spools 14, Fig. 5, may revolve around the loom. The spools 14 are carried by spindles 13 on the rim 1'2 of a container 7, which is rotated on ball bearings about a fixed vertical hollow shaft 4 in fixed casing 3 by worm gearing 48, 49 and a shaft 44, Figs. 2 and 5, driven by belt gearing from a motor 46. The shuttles 43 are driven more quickly than the spools 14 and in the contrary direction by rollers 26 on shafts 22 carried by ball bearings on a plate 18, which is rotated on ball bearings around the hub of the container 7 by large pinions 54 on shafts 52 carried by the container engaging a pinion 56 on the hub of the plate 18. Small pinions 53 on the shafts 52 engage a stationary ring 55. Spring-controlled plungers 25 act on the ends of the shafts 22 and force friction cones 27 thereon into engagement with friction members 28 on a circular member 11 of the container 7. The shuttles have rollers engaged by the rollers 26, and side supports 16 sliding in circular grooves in a raised crown 15 and in the member 11. The warps 41 pass from the spools 14 behind rods 32 and into guide-eyes 33, Fig. 6, in coiled spring metal wires 34 which are attached to angle brackets 35 and pass through notches in spring-controlled tappets 36 bearing on a fixed corrugated circular cam member 37, whereby the guide-eyes 33 are raised and lowered and the warp threads are selected. The core 42 passes through the hollow shaft 4 from a drum 97, which is braked by a weighted cord and is arranged at the top of two inclines 99 and held in position by two shoes 101 keyed by pegs 102. The sheathed core 91 passes through an open guide tube 94 carried by coils 92 to a slightly conical traction drum 61 driven through change-speed gearing, bevel gearing and worm gearing, a tail piece 89 on an adjustable slide 88 guiding the sheathed core, on to the drum 61. The sheathed core is finally wound on to a belt-driven drum 107 on to which it is guided by a grooved pulley 116, Fig. 7, on a member 117 traversed on a shaft 73, a double threaded screw on a shaft 122 driven by belt gearing, engaging a button 119 on a tail portion 118.
