Title: Improvements in or relating to pigments
Inventor: BIRRELL PETER
IPC: C08J3/215
Filed: 1961-11-03
Abstract: Pigment/polymer masterbatches are prepared by mixing an aqueous mass of pigment with a stable aqueous emulsified polyvinyl chloride or vinyl chloride/vinyl acetate copolymer, coagulating the mixture at a temperature ranging from the ambient to the boil, removing the aqueous phase from the coagulum and drying the solid so obtained. Optionally a known texture-improving agent such as finely divided calcium carbonate, pale American rosin or a cresol/formaldehyde resin may be added. The solid product may also be pulverised after drying. In examples the pigment dispersion is used to colour vinyl chloride polymers and nitrocellulose solutions.ALSO:Pigment/polyvinyl chloride or pigment/vinyl chloride-vinyl acetate copolymer master batches (see Division C3) are dispersed in vinyl chloride/vinyl acetate/maleic anhydride copolymer or nitrocellulose solutions which may be sprayed, spread or printed on to aluminium foil, polyvinyl chloride film, or metal panels.

Title: Improvements in and relating to the treatment of textiles
Inventor: BENNETT ALAN
IPC: D06M15/11
Filed: 1957-12-18
Abstract: An aqueous preparation suitable for treating textile fibres is made from an aqueous solution containing a catalyst and a urea-formaldehyde condensation product of a degree of condensation in which it has a low water tolerance (i.e. it is sufficiently hydrophobic to be thrown out of solution before, on dilution, the concentration falls to 10%), by diluting the solution with water in the presence of a hydrophyllic colloid so that the resin is thrown out of solution into intimate association with the colloid. The mol. ratio of urea to formaldehyde in the condensation product is preferably between 1 : 1,5 and 1 : 2, and the ratio of resin to colloid is preferably within the range of 1 : 4 and 4 : 1, although in the case of highly viscous colloids it may be as high as 15 : 1. Specified hydrophyllic colloids are starch, gelatine, carboxymethyl cellulose, polyvinyl acetate and polyvinyl alcohol, and suitable catalysts are acids, e.g. tartaric acid, and substances developing an acid reaction in the presence of formaldehyde, e.g. ammonium chloride or mono ammonium phosphate.  In Example (5) methanol is used as an additional solvent for gelatine.ALSO:In a process for filling, stiffening, glazing or delustering fibrous materials by impregnation with an aqueous preparation containing a hydrophyllic colloid, a urea-formaldehyde condensation product and a catalyst for the latter, a urea-formaldehyde condensation product of a degree of condensation in which it has a low water tolerance is used (i.e. it is sufficiently hydrophobic to be thrown out of solution before, on dilution, the concentration falls to 10%), and an aqueous solution thereof is diluted with water in the presence of the colloid so that it is thrown out of solution into intimate association with the colloid.  The necessity for baking the materials after impregnation is thus avoided.  The mol. ratio of urea to formaldehyde in the condensation product is preferably between 1 : 1,5 and 1 : 2, and the ratio of resin to colloid is preferably within the range of 1 : 4 and 4 : 1, although in the case of highly viscous colloids it may be as high as 15 : 1.  Specified hydrophyllic colloids are starch, gelatine, carboxymethyl cellulose, polyvinyl acetate and polyvinyl alcohol, and suitable catalysts are acids, e.g. tartaric acid, and substances developing an acid reaction in the presence of formaldehyde, e.g. ammonium salts.  The aqueous preparation is preferably applied to the fibrous materials by padding followed by drying on heated drying cylinders or passage between heated embossing rollers or glazing bowls to impart mechanical effects.  Specified fibres are cotton, viscose rayon and cellulose derivatives, e.g. cellulose acetate.

Abstract: 1,240,104. Memory field effect transistor. E.M.I. Ltd. 9 Sept., 1968 [8 Sept., 1967], No. 41111/67. Heading H1K. A memory element consisting of metal layers separated by an amorphous insulating layer at least 100 Š thick is disposed on the gate region of a JUGFET or the gate insulation of an IGFET. A stable resistive state is set up by application of a write-in pulse above a threshold value across the element. Information is read out as the transistor source-drain current by passing a sensing pulse through the element. With an IGFET or a JUGFET operating in the depletion mode a separation connection to each metal layer is required, but with an enhancement mode JUGFET since the write-in and read-out currents can traverse the forward biased gate junction a separate connection to the layer on the gate region is unnecessary. In the former case a bleed resistor connected to the gate contacting layer may be integrated with the device as a deposited metal strip or diffused track. Typically the memory element is vapour deposited on a silicon transistor element and consists of a layer of silicon monoxide or alumina sandwiched between gold and aluminium electrode layers. The element is electroformed in vacuo or dry argon and subsequently protected by mounting in vacuo or dry argon or by resin encapsulation.

Title: Tank closure caps
IPC: F01P11/18
Filed: 1966-09-15
Abstract: 1,087,760. Caps for vehicle radiators. GENEARL MOTORS CORPORATION. Sept. 15, 1966 [Sept. 29, 1965], No. 41283/66. Heading B8T. [Also in Divisions F4 and G1]  A cap. for a a motor car &c. radiator 10 is combined with a transparent rod &c. 56 which gives a visual indication as to whefther the level 12 of the liquid in the radiator is above or below a predetermined position. In the form shown, the rod 56 extends through the radiator cap 22 so that its top end 62 is exposed. The lower end 64 of the transparent rod 56 is in a plane inclined to the level of the radiator cap 22. The surrounding cylindrical face 66 of the rod 56, at its lower end, is coated with red paint. When the lower end of the rod 56 is immersed in the cooling liquid, light is refracted at the inclined face. 64 of the tube 56, and passes through into the liquid within the radiator 10. If the level 12 of the liquid falls below the inclined face (64), Fig. 3 (not shown), of the rod (56), light entering the top (62) of the rod is reflected, instead of refracted, at the inclined face (64), is then reflected on the red painted cylindrical surface (66) of the rod, back on to the inclined, face (64) where it is again reflected, up the tube (56) and out through the top (62). Accordingly, as seen from its top (62), the rod appears to be red, indicating the fall in the liquid level 12. In a modiification, the rob 56 is replaced by a plate (80), Fig. 5 (not shown), which may be flat or curved, having a lower surface (82) inclined in two planes with respect to the top surface (84). A continuous reading of liquid level (86) is thus obtained. The cap 22, Fig. 1, has a notched bayonet connection 20 with the rim 18 of the radiator filler tube 14, and carries a resilient metal sealing disc 26 which lies against the edge of the filler tube. The transparent level indicator rod 56 is gripped in a rubber sleeve 54 having its upper end 52 retained in a ring-shaped groove at the lower end of a generally tubular retainer 36, 40, 42. The tube 36 &c passes through a hole in the cap 22, and is biased downwardly by a spring 28 to engage a sealing ring 34 around a hole 32 at the top of the radiator 10. If an under-pressure develops within the radiator 10, air is drawn-in between the trans parent indicator rod 56 and its tube 36 &c and through the space between the rod and its rubber support sleeve 54. If an over-pressure develops in the radiator 10, the sealing ring 34 is forced away from its hole 32 against the bias of the spring 28, and excess pressure escapes through an overflow pipe 16.
