Patent FR-1602431-A (FR)
Title: Fabric patterning by colour addition
IPC: G03G15/16
Filed: 1968-12-13
Granted: 1970-11-23
Abstract: Monochrome or polychrome pattern is produced. An electrostatic image is formed from each elementary image of the colour image of the pattern, and is developed with electroscopic, pref. electrostatically charged, powder, of a colour corresponding to that of the elementary image. The powder image is transferred to the fabric. The different elementary images are successively formed on the same zone of the fabric, so that the desired image is synthesised. Pref. the image is first formed a photoconductive element. The powder is grains, beads or short filaments, which have a surface coat synthetic resin. A protective resin film is formed on top of the fabric image.

[Also in Division C5] An alkali metal tripolyphosphate hydrate is produced by reacting in a slurry and at a temperature below 135‹ C., preferably between 50‹ and 120‹ C., an alkali metal trimetaphosphate with an amount of a strong alkali metal base, viz. one that gives a pH of at least 10À2 in a 1% solution at 25‹ C., which is at least 50%, preferably at least 70%, of that stoichiometrically necessary to convert the trimetaphosphate to tripolyphosphate, the said slurry containing at least 35% by weight of the trimetaphosphate and at least enough water to hydrate the tripolyphosphate which is produced by the reaction. The base may be an alkali metal hydroxide, carbonate or silicate of SiO : M 2 O ratio lower than 2 (M representing an alkali metal cation), and the concentration of said base in the water constituent of the slurry is preferably at most 35% by weight. The slurry may also contain a hydratable inorganic salt to absorb any excess water.

Satisfactory acids include sulphuric, sulphurous, phosphoric, hydrochloric, formic, acetic, oxalic and citric acids, while such acid salts as sodium bisulphate and sodium dihydrogen phosphate may also be employed; the use of acetic anhydride is also envisaged. A particularly suitable refining agent comprises equal parts of 70% phosphoric acid and glycerol monostearate. If desired, adsorbents and filter aids such as fuller's earth, activated clay, charcoal, kieselguhr or asbestos fibres may also be added before the aqueous phase is separated from the oil.

Abstract: 1,226,351. Coatings. SPANG INDUSTRIES, Inc. 23 Feb., 1968 [24 Feb., 1967], No. 8789/ 68. Heading B2E. [Also in Division H1] A magnetic core assembly is coated by heating the assembly to 225F to 425F and applying an electrically insulating coating material to the assembly when it is at this temperature and partially curing at a temperature higher than 225F and not significantly higher than temperature of core assembly at the time of spraying so that pressure thereby generated within the core assembly is insufficient to cause bubble or pinhole formation in the so-formed coating. The electrically insulating material may be a liquid resin, containing a solid particulated organic filler and a volatile liquid vehicle. The resin may be a silicone, an alkyd, an epoxide, a silicone-modified alkyd or a silicone modified epoxide, and the filler may be silicone dioxide. A pigment such as molybdate orange or mercadmium red may be present. The coating may be applied by first coating a portion of the assembly and then coating the remainder before the final curing. The coating may be applied by spraying.

Abstract: 1,231,586. Photographic contact printing. GEVAERT - AGFA N.V. June 17, 1968 [June 20, 1967], No.28467/67. Heading G2A. Copying material, comprising a substance which absorbs light and emits heat causing permanent physical changes, e.g. in solubility, in a heatsensitive substance, is pressed into contact with a negative or print and is traversed by an exposure unit containing at least one discharge tube which flashes, so that areas of the copying material exposed overlap. In the embodiment shown, a copying sheet 47 and negative 48 are placed on top of a bed 11 and covered by a flexible transparent sheet 50. The bed 11 comprises a metal plate 46 soldered to rectangular metal tubes 45 which are connected to a vacuum pump to evacuate the space between the sheet 50 and plate 46 through perforations 51 so that the sheets 47, 48 are pressed together. An exposure unit 12, driven by an electric motor, successively engages a series of posts 39 which in turn trip a micro-switch 37 on the unit causing a xenon tube (42), Fig.4, (not shown) to flash. At the end of its run, the unit 12 engages a post 30 which trips a micro-switch (29) reversing the motor, disengaging switch 37 and bringing into the circuit a switch 38 which is tripped by a series of posts 40, offset from the posts 39, to illuminate areas of the sheet 47 missed on the outward run. The sheet 47 is then removed and developed. Instead of the negative 48, a print may be placed between the plate 46 and a copying sheet, the latter being rinsed and dyed after exposure to provide a master for conventional duplicating. The xenon tube (42) is located at a focus of an elliptical reflector 27 which is dimpled and aluminium plated to diffuse the light.

Abstract: 1,232,457. Fluid pressure brake actuators. BERG MFG. (U.K.) Ltd. 7 May, 1968 [8 May, 1967], No. 21482/68. Heading F4F. A brake actuator comprises a first piston 4 normally used to displace an actuating arm 10 to apply the brake and a second piston 20 which can be used if necessary, when, due to improper adjustment, thermal expansion, or wear, the brake is inadequately applied when the piston 4 has reached its limit of travel, to displace the actuating arm 10 relative to the first piston in the brake-actuating direction. As shown in Fig. 1, the first piston comprises a diaphragm 4 and is operated by supplying pressure fluid to inlet 5 to displace the diaphragm 4 against the action of a return spring 7. Piston 4 reaches its limit of travel when a flange 6a abuts the end wall of chamber 2. The second piston 20 is operated by releasing the pressure in front of the piston so that a spring 23 urges the piston 20 forwards and when plate 25, carried on extension 20a, contacts the diaphragm 4 it pushes it into the central recess 8 of the plate 6 thereby displacing the actuating arm 10 relative to plate 6 against the action of a spring 15. In an alternative arrangement, Fig. 3 (not shown), the end of the actuating arm (110) passes sealably through the diaphragm (104) to co-operate directly with the extension (20a) of the second piston and the return spring (107) acts against a shoulder (112) on the arm (110) instead of on the plate 6.

The nippers 2, 3 of a circular comb machine are mounted so that part of the path travelled by the lap outlet of the nippers is concentric with the circle 1 travelled by the needles of the comb. The drive means for the lower nipper 2 includes a first rocker arm 4 pivoted about the axis of rotation of the comb, a second rocker arm 5 adapted so that the distance between the fulcrums at its ends can be varied, and a first connecting rod 21 linking the rocker arm 4 and 5 and carrying the lower nipper. There are also means, e.g. stops 22, 41 or a restricted pivot B, which limit the change in angle between rocker arm 4 and the connecting rod 21. The stops 22, 41 can bear against each other or against the connecting rod 21. The upper nipper 3 can be driven by means including third and fourth rocker arms 31, 7 and second and third connecting rods 6 and 8, rod 6 being adapted so that the distance between its fulcrums can be varied. In an alternative embodiment (Fig. 3) connecting rod 6 is connected to a fixed point instead of fulcrum H. The upper drive can drive from shaft J, or the upper nipper can be moved by a cam. Rod 6 can be releasably connected for cleaning purposes.
