Title: Improvements in or relating to luminescent screens
IPC: H01J29/18
Filed: 1939-10-25
Abstract: 535,947. Luminescent screens. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 25, 1939, No. 28706. Convention date, Oct. 25, 1938. [Class 39 (i)] Luminescent screens for use in signs, lamps, cathode ray tubes and X-ray fluoroscopes have two different layers of material arranged in order of their light absorbing qualities ; the phosphor 13 which only absorbs in the ultraviolet range is placed first on the screen when viewing is effected outside of the glass 11 and the other phosphor 15 which absorbs in the visible range is placed on the first layer. As a consequence the light emitted by the first layer is not absorbed and mixes with that from the second to produce a desired white light. If the light is viewed from the same side as radiation is effected the positions of the layers are reversed. The light absorbing phosphor may be zinc cadmium sulphides with or without silver or copper, zinc sulphide with copper and zinc cadmium manganese sulphides ; also some tungstates and silicates. For the relatively non-light absorbing phosphors zinc sulphide pure or silver activated, zinc silicates manganese activated, zinc beryllium silicate and some tungstates may be used. The layers may be applied by binders or may be settled out of suspension, one layer after the other. Willemite may also be used, its rough particles holding the finer sulphide particles subsequently placed thereon. Specifications 388,623 and 474,907 are referred to.

Title: Improvements in or relating to raising machines for treating textile fabrics and other sheet material
Inventor: PILKINGTON NORMAN
IPC: D06C11/00
Filed: 1954-10-07
Abstract: 787,028. Abrading rubber sheeting etc.; pileraising machines. TOMLINSONS (ROCHDALE), Ltd. Dec. 19, 1955 [Oct. 7, 1954], No. 28862/54. Classes 31 (1) and 42 (1). A planetary type single or double acting wire card pile-raising machine has a device adapted to indicate a condition or conditions at the point of contact of the fabric and the rollers, whereby there is given an indication when the rollers are being driven at the appropriate speeds to give " zero raising " action (i.e. with no speed differential between the wires of the card clothing and the material being treated); the indication is visible, audible or otherwise discernible without mental calculation or comparison. In addition to treating textile fabric, the machine may be used for abrading rubber sheeting or other continuous web material. As shown, Fig. 2, the gear wheel 15 carrying the driving belt for the pile rollers 12 is driven from the main cylinder shaft 14 through a chain drive, an infinitely variable gear-box 19 and a pinion 21. The counter-pile rollers 13 are similarly driven via a gear-box 20 and a pinion 22. The chain driving gear-box 19 has a " driving " run 24, Fig. 3, and a " braking " run 25; when pile rollers 12 are exerting a raising action the braking run 25 will be taut, and under zero raising conditions the tension of both runs fluctuates between slackness and tautness. A wheel 27, on a pivoted arm 26, rests on the chain run 24, the end 26b of the arm lying between two switches 28, 29. The arrangement provides that when chain run 24 is in tension, switch 29 is operated to light a green lamp 30; when the tension is fluctuating (during zero raising) a yellow lamp 31 is lit; and when run 24 is slack (during raising) switch 28 is operated to light red lamp 32. The chain driving gear-box 20 is always under tension on the driving run 33 since the counter-pile rollers 13 are positively driven during raising, and oven during zero raising friction and inertia have to be overcome. A spring-loaded jockey-wheel 41 bears on chain run 33 with sufficient pressure to keep chain run 34 taut during zero raising; during raising, however, the tension in run 33 is sufficient to displace wheel 41 and slacken run 34. A wheel 36 bearing on run 34 acts, similarly to wheel 27, to operate three lamps 37, 38, 39, one of which indicates raising and the other two zero raising. Instead of lamps, an audible signal, such as a buzzer, could be used.

Abstract: 1408364 Electrically conductive coated sheet DYNAMIT NOBEL AG 20 June 1973 [22 June 1972] 29398/73 Heading B2E  An antistatic or electrically conductive sheet structure suitable for use as a floor covering comprises a thermoplastic plastics sheet which is substantially electrically non-conducting and has a number of holes passing therethrough and an electrically conductive material covering one side of the sheet and extending through and filling the passages from said side to the other side which remains uncovered with the material. The plastics sheet may be of PVC, polyolefin or vinyl chloride-olefine copolymer and the conductive coating may be of ethylene-vinyl chloride copolymer paste containing carbon black which is applied by doctoring or rolling on. The holes are usually of conical cross-section and are formed by needling the plastics sheet after heating to 40-60C. The conductive paste is then applied and the sheet heated to a temperature from 60C to the gelling temperature of the paste to cause contraction of the holes and, thereby force the paste through the sheet followed by grinding off of excess paste on the other side. Alternatively, both sides of the plastics sheet may be coated followed by healing and then splitting of the product along its median to produce two sheet structures.

Abstract: 1280452 Milling textiles NEIL & SPENCER Ltd 19 Sept 1969 [20 June 1968] 29512/68 Heading D1P and D1S In a process for the milling of textile goods containing wool the goods are subjected to mechanical action while wetted with an organic solvent/surfactant mixture in which water is dissolved, for a time (5 to 11 min) and at a temperature to produce the desired change in the goods treated. Suitable organic solvents include halogenated hydrocarbons for example perchlorethylene and trichlorethylene and petroleum hydrocarbons, perchlorethylene being preferred. The surfactant can be anionic, cationic or non anionic (sodium naphthalene sulphonate is quoted) and it comprises 0.5 to 5% preferably about 1.5% by volume of the organic solvent/surfactant mixture. The water content of the mixture is in the range sufficient to maintain a relative humidity of between 75 and 99.9% preferably 80 to 98% in equilibrium with the mixture. Suitable temperatures are constant to within Œ1‹C of a mean lying between 26 and 33‹C. The tumbling action is produced by means of an apparatus similar to a dry cleaning machine. After treatment the material is dryed by centrifuging and then passing warm air through it. The apparatus consists of a housing 2 containing a rotatable perforated drum. Solvent is available in tank 4 and is brought to the required humidity by being pumped past electrical sensing device 14 which operates supply of water or steam to pipe 18. Thermostat TC prevents supply of water until the temperature exceeds 26‹C and thermostat TA operates similarly for steam at temperatures in excess of 29‹C. Water enters cooler 10 when the solvent temperature exceeds 33‹C as monitored by thermostat TB. A heater 12 is provided. Pump 19 supplies solvent to drum 2 and solvent is circulated through the drum by opening valves V 2 , V 4 . Warm air is supplied by ducts 30, 32, 34, fan 40 and heater 38. Cooled air provided by cooler 36 condenses solvent which is returned to tank 4.
