Abstract: 1,228,817. Lasers. SIEMENS A.G. 19 Aug., 1968 [19 Aug., 1967], No. 39550/65. Heading H1C. A laser is compensated for mechanical distortion due to thermal effects. A helium neon gas discharge tube 1 is held by two thermally conductive plates 3a, 3b mounted on three symmetrically arranged connecting rods 4 of good thermally conductive material. The rods 4 are covered by a layer of thermally insulating material 5 so that direct incidence of radiation on the connecting rods 4 is avoided and the connecting rods 4 remain in a state of equilibrium at a temperature determined by the support plates 3a, 3b and support plates 2a, 2b supporting the resonator mirrors 15. The rods 4 will therefore expand equally on heating and maladjustment of the support plates 2a, 2b will not take place. By covering the support plates 3a, 3b and 2a, 2b with a layer of thermally insulating material a temperature gradient along the surfaces of the support plates due to non- uniform heating of the support plates is prevented. In order to compensate for radiation of heat from cathode 7 taking place anisotropically as regards rotational symmetry about axis 11 the branch 6 of the discharge tube 1 is surrounded by a thermally conductive ring shield 12 having a widened portion 13 in the neighbourhood of cathode 7. Heat energy radiated on to the portion 13 is uniformly distributed over the whole of shield 12 and is transmitted by the latter to a housing 19 enclosing the laser. Non-uniform heating of housing 19 along its periphery is thereby avoided and warping of the housing which may result in misalignment of the mirrors eliminated. Thermally conductive connections are made between the shield 12 and housing 19, Fig. 2 (not shown). The layer of insulating material 5 may be sprayed on or be in the form of prefabricated tubes and it may be coated with a layer of metal which reflects incident heat. The Brewster angle windows 10 and resonator mirrors may be enclosed in a fluid tight manner and the remainder of the housing formed by this metal layer. Adjustment of the mirrors 15 may be made by screwthreaded ring 18. An optical system for enlarging the diameter of the laser beam may be screwed on the holder 16/17.

Abstract: 1,229,286. Closures for containers. CONTINENTAL CAN CO. Inc. 22 July, 1968 [25 Oct., 1967], No. 34797/68. Heading B8D. An easy opening can end for a sealed can having an internal pressure other than atmospheric, comprises an end panel having a removable portion 22 defined by a continuous score line 21, and a pull tab 23 secured to the removable panel portion 22 and being arranged to rupture the end panel along a predetermined portion 28 of the score line 21. The end panel is resistant to uncontrolled movement of the removable portion 22 during pressure equalization after initial rupture, in that the score line 21 is of a lesser depth than the predetermined portion 28 on opposite sides of the predetermined portion 28. This reduction in depth of the score line, while being sufficient to prevent the uncontrolled propagation of the crack along the score line 21, is not so great as to prevent the rupture thereof utilizing the pull tab. Beyond the shallower score line portions (30) (Fig. 3, not shown) the score line 21 is of substantially the same depth as the score line portion 28. The removable panel portion 22 may be provided with an anti-fracture score line 25 adjacent to the continuous score line 21 for facilitating flexing of the removable panel portion during rupture and for relieving strain along the continuous score line 21. This anti-fracture score line 25 may have a longitudinal depth profile analogous to that of the score line 21. The end panel may have a recessed central portion 26. A pair of buttons 27 may project upwardly from the recessed portion to support the inner part of the pull tab to facilitate the initial lifting of the pull tab. The score lines are formed by a die and an anvil, the die having ribs or the anvil having recesses of the required configuration and giving respective different profiles of score line cross-section.

Abstract: 1,234,492. Controlling soaking pit furnaces; regenerative furnaces. LEEDS & NORTHRUP CO. 8 July, 1969 [8 July, 1968], No. 34343/69. Headings F4B and F4K. [Also in Division G3] In a reversible regenerative soaking pit furnace 1 having regenerative chambers 2, 3 and associated burners 8, 9 and wherein reversal is effected through a control damper 6 and fuel valve 10 both actuated by a relay system 11, the direction of flow through the furnace is controlled in response to a change in the firing state of the burners. A timer 18 is started each time a burner is switched on. In operation, furnace reversal is regulated in response to two different criteria as follows: When the ratio of "fuel on" time to the total time between successive reversals, as computed by networks 12, 13 and 14, is above a preset value, e.g. 50%, the timer 18 actuates furnace reversal through the relay system 11 after a predetermined time interval. When the ratio is below the preset value, reversal of the furnace is controlled by a temperature responsive system. The output of a thermocouple 15 measuring the temperature in the furnace is applied to a temperature recorder 17 which has a balancing network of conventional type to which a pen is connected. At a predetermined point in the travel of the pen, the contact 16 is opened and closed. This contact may be used to turn the burners 8 and 9 on and off. An indicator 23 is provided to indicate when the furnace is "soaked out" i.e. the contents of the furnace have uniformly reached the desired temperature. The indicator is actuated when the ratio of the "fuel on" to "total time" reaches a constant value.

Abstract: 1,253,160. Polyphenylene oxides. GENERAL ELECTRIC CO. 22 Dec., 1969 [23 Dec., 1968], No. 62359/69. Heading C3R. A poly-(phenylene oxide) P, having a number average molecular weight of at least 10,000, is composed of repeating units A and B the no. of B units being 0-5-10% moles based on A+B. R a  is CH 3 - or C 6 H 5 -; R b  is CH 3 -S- or CH 3 -S-CH 2 -; R c  is CH 3 - or C 6 H 5 -, or, where R b  is CH 3 -S - , R b  may be CH 3 -S-CH 2 -. P may be made by oxidatively coupling phenol C with phenol D C and D may be mixed before oxidative coupling, or segmented polymers may be formed by first coupling one of the phenols and thereafter adding the other phenol. The oxidative coupling may be performed by passing an O 2 - containing gas, e.g, air, into a solution in an inert solvent, e.g. toluene or benzene, of a Cu amine complex and the phenols. The copolymer may be capped by reaction to convert terminal OH gps. to inert or highly oxygenresistant substituents, e.g. by esterifying with acid anhydrides or acyl halides, or etherifying. In examples, O 2  is passed into solutions containing (CH 3 ) 2 NCH 2 CH 2 N(CH 3 ) 2 , (CH 3 ) 3 N, and Cu 2 Cl 2 , and anhydrous MgSO 4 . Solutions of the phenols in benzene are added; the reaction mixture is immersed in a water-bath at 25 C. When indicated intrinsic viscosity is 0-6 dl/g, corresponding to MW of 30,000, the solution is filtered through activated A1 2 0 3  to remove the Cu-catalyst and MgS0 4 . P is then precipitated by addition of CH 3 OH, filtered, and dried. Two solutions T and V of P in C 6 H 6  are made. T is titrated with the Li ketyl of benzophenone, and an excess of acetic anhydride is added, thus capping P with acetate groups, forming cold-capped polymer CC in solution. V is sealed in a pressure-vessel with excess acetic anhydride and heated to 250 C., yielding hot-capped polymer HC in solution. Some of the CC in solution is hot-capped yielding polymer CCHC in solution. CC, HC and CC-HC are then precipitated with CH 3 OH. The uncapped and capped polymers can be compression-moulded, or blended with other polymers, e.g. polyolefins, polystyrene, or styrene copolymers. Fillers dyes and pigments may be added.

Abstract: 1290302 Casting building components BATIR 21 April 1971 [17 Sept 1970] 10581/71 Heading B5A Building components, e.g. individual rooms for prefabricated dwellings, comprising four longitudinally extending walls forming top, bottom and two sides successively cast horizontally on the four walls of a rotary mould, are formed by first detachably securing longitudinally extending angle corner members to the four internal corners of the mould and spaced therefrom by the thickness of the wall of the component, and utilizing these corner members to hold bracing members for sheet-metal or plywood panels in position, so that each wall can be cast and the mould then turned through 90 degrees without waiting for the previously cast wall to set. The mould consists of top and bottom sections 11 and 10 and side walls 12 carried within circular members 7 supported on rollers 8 by which the mould assembly may be rotated through an angle. The mould top and side walls are supported from hydraulic cylinder and piston units 13 which enables them to be moved apart or together slightly. The bottom wall 10 is mounted on rollers so that it can be moved out from the mould along the longitudinal axis. The four angle irons 20 are positioned at the corners of a jig 17 (Fig. 5) and reinforcement mesh 19 is placed therearound. This assembly is placed on the mould bottom and rolled into position in the mould which is clamped together by the hydraulic units. The angle irons carry tapered spacers (Fig. 7, not shown) through which they are bolted to the mould walls at the correct distance therefrom. Each angle iron carries corner gussets to which cross-members can be secured by pegs. Prefabricated cast end walls are secured in position and the bottom wall is then cast and tamped, after which a sheet of metal or plywood is laid over, beams are laid across this and metal crossmembers are laid across the beams and locked in position at their ends by pegs through the gussets previously mentioned (Figs. 9-12, not shown). The mould is then turned through 90 degrees and the process repeated with each wall in turn. The corner angle irons are then unbolted, the mould walls moved outward, and the cast unit taken out on the movable base 10, which is run on to transverse rollers on guide rails which enable the casting to be transported to a position where it can be dried, e.g. by hot panels or steam jets. The angle iron, crossmembers, braces and panels are then removed.
