Title: Liquid crystal devices
IPC: G02F1/1343
Filed: 1975-12-12
Abstract: 1502810 Liquid crystal displays DEFENCE SECRETARY OF STATE FOR 12 Dec 1975 [14 Jan 1975] 1630/75 Heading G5C [Also in Division G2] At least one of a pair of electrodes 7 either side of a liquid crystal layer has a plurality of perforations 22. On application of a potential difference between the electrodes only partial realignment of the liquid crystal molecules occurs at the edges of the perforations as the field strength changes and the resulting refractive index gradient gives a highly scattering optical state. The liquid crystal material is preferably nematic with positive dielectric anisotropy, e.g. in a "parallel rubbed" variably birefringent cell, or a twisted nematic cell, or it may have negative dielectric anisotropy, e.g. in a cell having both surfaces coated with lecithin to promote homotropic alignment in the unenergized state. The electrode may be shaped or segmented and perforated uniformly throughout, for a display corresponding to the electrode shape, or selected areas of the electrode may be perforated, for a display corresponding to the selected area and the electrode edge. The perforations occupy 20-80%, and typically 50%, of that area of the electrode which includes them. A reflector or black board may be disposed behind the cell.

Title: Improvements relating to the control of electrically driven textile machinery
Inventor: HOLT FREDERICK BRERETON
IPC: H02P7/08
Filed: 1953-01-20
Abstract: 735,198. Controllers. METROPOLITAIN-VICKERS ELECTRICAL CO., Ltd. Dec. 31, 1953 [Jan. 20, 1953], No. 1653/53. Class 38 (3). A textile or other machine of considerable length has an induction driving motor 13 which is adapted to be controlled from a number of stations such as OP1, OP2, situated at intervals along the front of the machine. A controller 2, similar to that described in Specification 689,323 is provided, and its main shaft has an axial extension 3 journalled in a bearing block 4 and carrying a boss 7. To start the machine, an operating lever 21 at one of the control stations is moved to rotate an actuating shaft 6 extending along the rear of the machine and carrying a boss 14 having two radial arms of different lengths. The shorter of these radial arms carries a stud for engaging an arm secured to the boss 7, another arm on this boss being coupled through wire 12 to the brake mechanism of the motor, so that initial movement of an operating lever energizes the driving motor although acceleration of the machine is retarded due to the braking-action. When the machine is to be operated at full speed, the control shaft 3 is moved to a position in which it is retained by an electromagnetic hold-on device, the braking torque being reduced to zero. The operating lever 21 may then be released and automatically returned to a neutral position. Alternatively, inching operation may be obtained by moving the operating lever partly towards the fullspeed position and then returning it. The machine may be stopped by moving one of the control levers 21 opposite to the starting direction from the neutral position, the longer arm 15 on the boss 14 co-operating with a stop-switch. The actuating shaft 6 may comprise a number of coupled lengths of axially aligned shafting with lost-motion coupling therebetween, so that only those shaft lengths between the control station in use and the controller will be rotated. The controller 2 may be located at an intermediate position with regard to the actuating shaft, in which case the controller shaft is extended in both directions.

Patent GB-853518-A (GB)
Title: Water-dispersed pressure-sensitive tape adhesives
IPC: C09J7/21
Filed: 1957-01-16
Abstract: A pressure sensitive adhesive is prepared by forming a stable aqueous dispersion of a neutral tackifying resin in the form of an impalpable powder, and mixing it with a natural and/or synthetic rubber latex. The tackifying resin may be a terpene resin or pentaerythritol abietate.  The synthetic rubber latex may consist of an aqueous dispersion of an butadiene-styrene copolymer. Antioxidants, fillers, dyes, pigments, and vulcanizing agents and accelerators may be incorporated in the blend, preferably as preformed aqueous dispersions.  In an example an aqueous dispersion is prepared by agitating in an attrition mill a mixture of water, a powdered thermoplastic terpene resin, partially polymerized rosin, ammonium hydroxide, and 2,5-ditertiary amyl hydroquinone (as an antioxidant for the resin).  The partially polymerized resin reacts with the ammonium hydroxide to form a water soluble soap serving as a dispersing agent, which on subsequent drying reverts to a water-insoluble tackifying resin. There is then separately prepared in the attrition mill an aqueous dispersion containing polymerized rosin or dehydroabietic acid, ammonium hydroxide, and 2,2 methylenebis(4 methyl-6-tertiarybutyl phenol) as rubber antioxidant. The two dispersion are blended with concentrated natural rubber latex to produce a composition containing (in parts by weight), rubber 100, neutral tackifying resin 89, soap forming resinous acids 5,6, antioxidants 4,8, ammonia 0,7, and water 151.  An adhesive tape is produced by applying the adhesive to a surface of a tape of cellulose acetate, or a fibrous or paper sheet impregnated with synthetic rubber composition.

Filed: 1937-01-25
Abstract: 492,745. Sterilizing liquids. KATADYN AKT.-GES. Jan. 25, 1937, No. 2140. Convention date, Jan. 24, 1936. [Class 41] [Also in Group VI] Easily perishable colloid-containing liquids such as sweet cider which are to be stored foi prolonged periods (i.e. more than four weeks) in quantities of, say, 5 gallons upwards in barrels, vats or the like, in which they may be subject to recontamination, are preserved by continuous or periodic electrical reactivation with oligodynamically active material during the whole period of storage. The liquids may be clarified before electro-oligo. dynamic treatment. A strong preactivation of 2-3 mg. of silver per litre may be followed by continuous or periodical feeble reactivation. Continuous reactivation may be effected with current of the order of 0À02 milliamps per litre or periodic reactivation with current of the order of 0À05 milliamps per litre applied for a period from several hours up to a day, the electrolytic efficiency in both cases being about 50 per cent. Continuously applied current of varying strength may be employed. Lower current values may be used for enzymatically clarified liquids. Stronger currents for shorter periods may be employed. The storage barrels may be provided with openings on either side of the bung-hole for the suspension of electrodes, and with means for agitation by mechanical means or by the introduction of nitrogen or carbon dioxide. A suitable electrode comprises a hollow cylinder 30, e.g. of synthetic resin on which is wound a band 31 of oligodynamically active metal. The terminals consist of a tapped socket 36 mounted in an internal flange 33 and a screw bolt 37 mounted on an end-piece 34 fitted with a rubber packing 41. Two or more electrodes may be fitted together by engagement of the plugs and sockets. The electrodes may alternatively consist of silver tubes or silver wires. The polarity of the electrodes may be reversed periodically, e.g. by a time switch. The metal content may be removed from the liquid before consumption, e.g. by precipitation with potassium ferricyanide. Specification 431,872, [Group VI], is referred to. The Specification as open to inspection under Sect. 91 includes oligodynamic activation by contact without the use of electric current. This subject-matter does not appear in the Specification as accepted.

Abstract: 734,272. Conveyers. BAKER PERKINS, Ltd. April 24, 1953 [Jan. 25, 1952], No. 2149/52. Class 78 (1). Articles travelling with regular spacing are formed into batches or vice versa by a plurality of independent article-receiving surfaces or article-engaging members which are driven independently and successively at progressively different, speeds by direct engagement either directly or through the intermediary of lengths of chain connected to the members with sprocket wheels driven at progressively different pitch circle velocities, the sprocket wheels being spaced such that each member or associated chain can only be engaged by one of the sprocket wheels at a time. As shown, two pairs of duplex chains 5, 7 are arranged in a pair of guide tracks 26, one each side of the machine so that while one pair is engaged with a pair of sprockets 2 rotating clockwise (Fig. 3), at a fast peripheral speed, the other pair is engaged with a pair of sprockets 3 rotating in the same direction at a slower peripheral speed. The trailing ends of the pairs of chains 5, 7 are secured to the leading ends 39 of flexible plaques 4, 6 respectively, which are thereby moved over a table 40 by the chains so that one plaque is moving faster than the other for half a cycle and vice versa during the other half cycle. The plaque travelling at the faster speed is always the one passing over the end of table 40 adjacent thesprockets 3 while the slower plaque is always the one passing over the end of table 40 adjacent the sprockets 2. In operation, articles fed continuously by a feed belt 22, tensioned by a spring-pressed roller 49, on to the plaques, travel at first at a slow speed, and as the plaque on which they are resting reaches the delivery end of table 40 the articles are speeded up to-space them in batches equal in length to the length of each plaque, the batches being removed by a delivery belt 23 moving at a faster speed than the feed belt 22. A continuous support for the plaques is ensured by rollers 32, 33 extending between the sprocket of each pair 2, 3, for rotation therewith and guide rods 41 for the lower run. Axial grooves 43, 44 are provided in the peripheries of the rollers 32, 33 to accommodate the connecting means in the form of trans. verse rods securing the leading ends of the plaques to the trailing ends of the chains 5, 7. Also to ensure that the trailing ends of the plaques remain in close relationship to the roller 33 as they pass around it, bores 35, 37 are drilled in roller 33 arranged so that during rotation the bores 37 register with a suction box 38 at the same time as the bores 35 come under the trailing edges of the plaques. The sprockets 2, 3 and the belts 22, 23 are all driven in suitable timed relation through a drive chain, not shown, engaging suitably proportioned sprockets on the various drive shafts.
