An apparatus for the surface treatment of glass by the substitution of cations by larger cations by means of electromigration includes a receptacle 20 having an open end over which the glass sheet 24 to be treated may be disposed and means such as a vacuum line 32 to create a vacuum within the receptacle, thus securing the sheet against the edges of the receptacle; a first electrically conductive liquid 38 in the receptacle 20 and in contact with the glass surface; a second electrically conductive liquid 16 in contact with the opposite surface of the sheet; and electrodes 36 and 50 to connect the liquids to opposite poles of a direct current source. The liquids may be chemically identical and may be molten potassium nitrate. The receptacle 20 can be raised or lowered by means of a rack and pinion 29, 30 and pivoted about joint 23 by means of a double-acting jack 27. The receptacle 20 is supplied with liquid by means of a syphon from a compartment 48 of the tank 14 which contains the second liquid 16.

Abstract: 1296341 Laminates IWS NOMINEE CO Ltd 19 April 1971 [1 Jan 1970] 105/70 Heading B5N [Also in Division D1 A non woven fabric is made by passing a loose array of keratinous fibres in the presence of water through a bed of particles which are maintained in a state of vibration. The process causes the fibres to interlace with one another. The array of fibres can be passed into a bath containing glass or metal balls which are vibrated mechanically or magnetically. The fibres can be sprayed with water or passed through a separate bath before contact with the vibrating particles. The initial arry of fibres can be formed by carding or combing. The fibre array can be passed through a plurality of beds of particles with further layers of fibres being applied as it enters each bed so as to produce a thick fabric. Alternatively the fibres can be passed through one bed a number of times, or through a plurality of beds to produce a thinner dense fabric. The array of fibres may be sandwiched between flexible plastics films during passage through the bed(s). The fibres may be attached to one or both sides of a knitted or woven reinforcing web during passage through the bed(s). Attachment of the fibres may occur by enmeshing of the fibres under the action of the vibrating particles alone, or by the use of an adhesive. The fibres can be wool and they may be blended with polyester fibres. The water may contain a swelling agent, e.g. area, area and bisulphite, or sodium carbonate and surface active agents. The treatment of the web in the vibrating particle bed may be carried out at a temperature of 40-70‹ C.

A differentiator (Cf, Rg) produces a deceleration signal at the base of a transistor (Tc) which drives switching transistors (Td to Tg). A normally off solenoid 6 (S) is operated when the deceleration exceeds a value determined by the values of the differentiator components (Cf, Rg). The solenoid operates a control valve 7 to release a wheelbrake even if the pedal F.P. is still operated. A resistor (Rf) and capacitor (Cg) ensure that the relay is de-energized to reapply the brake after a certain time even if the wheel does not fully decelerate.

Abstract: 1327964 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 11 Jan 1972 [12 Jan 1971] 1554/71 Heading G6C The integrity of fission product-retentive coatings applied to nuclear fuel kernels to form coated particles is tested by weighing the coated particles, either as loose particles or as a fuel compact, heating the particles after weighing to a temperature which in the event of any defective coating will result in the evolution of a gas and the release of the gas evolved, and then reweighing the particles and measuring any weight loss to determine whether a release of gas has occurred. Where the kernels include UO 2 , this may react with carbon also in the kernels or with pyrocarbon of the innermost coating layer. Where the fuel material is UC, a normally passive oxide is incorporated in the kernel or the innermost coating layer, such oxide becoming active when heated to higher than carbonization temperatures preparatory to the first test weighing. The gas-evolving reaction occurs at temperatures above 1300 C., and one possibility is to weigh the fuel before and after the degassing of the fuel which is the end process step in the manufacture of the fuel and during which the fuel is heated in vacuo to 1800 C. At this temperature and in the event of a defective coating, there will be reaction between elements in the kernel or between elements in the kernel and the innermost layer of the coating, and the amount of gas evolved and released will be a significant, measurable quantity.

Abstract: 1328633 Fluid-pressure servo-control AUTOMOTIVE PRODUCTS CO Ltd 13 Oct 1970 [15 Oct 1969] 50675/69 Heading G3P  In a multi-channel control system for aircraft wing flaps, interconnected duplicate control linkages (34, 35) are connected to duplicate floating levers 23, 24 by respective connections 25, 27, 29, 32 and 26, 28, 31, 33, and in normal operation levers 23, 24 operate control spool 17 to provide follow-up control of the cylinder 51 of a servo-motor 10 having a fixed piston 52. If one of levers 23, 24 e.g. lever 23 should seize, the remaining lever 24 pivots about its connection to the temporarily locked spool 17 and displaces rod 39 by a distance corresponding to the clearance between plunger 121, 123 and slot 122, pilot spool 49 thereby being raised by ball 45 and lever 46 to dcpressurize chamber 124 above plunger 121, 123 and chamber 74 of a fluid clutch 18. End 73 of spool 17 is thereby decoupled from seized lever 23, and plunger 121, 123 retracted by spring 125 allows springs 43 to return rod 39 and lever 24 to the position shown. If lever 24 seized instead of lever 23, the above sequence would be repeated, except that rod 38 would operate pilot spool 47 to depressurize clutch 19 and left-hand chamber 124. If the control spool 17 should seize, with one or both of levers 23, 24 free, the resulting displacement of rod 38 and/or 39 raises pilot spool 48 via lever 46 to depressurize chamber 83 in bypass spool 76, allowing spring 93 to shift the spool leftwards to disconnect the source 95 and reservoir 102 from the supply and exhaust ports of housing 11 of control spool 17. Spool 76 also interconnects opposite sides of servo-motor piston 52 via 62, 64, 66, 81, 67, 65, 63, allowing cylinder 51 to be moved by the aerodynamic forces on the wingflap. Pilot spools 47-49, when raised, are held in that position by fluidpressure acting on their lower ends. Snub valves 137, 138 as disclosed in Specification 1327393 control outflow from chambers 55, 56 when contacted by piston 52 to dampen cylinder movement at the ends of the working stroke. Microswitch 92 indicates seizure of control spool 17. In systems using a single-acting servo-motor, bypass spool 76 would be replaced by a vent valve for the working chamber.
