Filed: 1965-02-26
Abstract: 1,031,003. Lasers. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1965, No. 8354/65. Heading H3B. Mode reduction in a laser is obtained by the use of two collinear lengths of active material 1, 2 which are separated by an optically attenuating film 3. Each length of active material has polished and plane parallel ends, and a compound resonator is formed by silvering the outer ends 4, 5. The active material may be ruby or neodymium-doped glass, while the optically attenuating film may be an evaporated layer of silver, gold, copper, aluminium or indium having a thickness in the order of 250Š. This metal film will introduce larger bosses in some modes than in others, depending on the magnitude of the electric field at that point, those modes having a node at the film having the lowest loss and the lowest threshold for oscillation. The arrangement is applicable to gas lasers.

Title: Preparation of oxidized cyclohexane
IPC: C07C45/53
Filed: 1952-04-02
Abstract: Cyclohexanone and other products are obtained by the catalytic decomposition of cyclohexylhydroperoxide in oxidation mixtures from cyclohexane, by means of acid or boron trifluoride, or source of metal ions, especially a cobaltous compound.  In the oxidation of cyclohexane in liquid phase with molecular oxygen, which precedes the decomposition of the hydroperoxide, preferably no catalyst or very small quantities of Co-containing catalyst are employed.  The products containing also some cyclohexanol may be converted directly to adipic acid.  Specification 633,354 is referred to.  The decomposition catalyst is introduced when the production of hydroperoxide is at a maximum so that it suffers no thermal decomposition.  Examples are given in which the oxidation mixture at a concentration of peroxide of 1.57-7 per cent is withdrawn or other solutions of hydroperoxide are concentrated, and withdrawn and sulphuric acid, cobalt naphthenate, gaseous boron trifluoride, acetic acid, and perchloric acid are used to decompose the hydroperoxide to give mixtures containing a high proportion of cyclohexanone to cyclohexanol after distillation and separation.  Tables show the rate of decomposition of the hydroperoxide with various catalysts.

Patent GB-371560-A (GB)
Title: Improvements in machines for the so-called dry cleaning of textile materials
IPC: D06F43/02
Filed: 1931-03-20
Abstract: <PICT:0371560/IV/1> <PICT:0371560/IV/2> <PICT:0371560/IV/3> In a dry-cleaning apparatus, the entire drive for producing the washing operation and centrifuging operation, and for driving the fan which sucks gases from the drum, is effected by wheel gearing operating in an oil bath in closed casing, the change-over from washing to centrifuging operation being obtained by the movement of a sleeve carrying gear wheels and mounted on the driving shaft. The drive from a motor or pulley to the shaft is transmitted through an elastic member, for example, a centrifugal clutch.  On starting the apparatus for the washing operation, the sleeve 19, slidably mounted on the driving shaft 8, is moved to the position at which its toothed wheels 20<1>, 20 engage with the toothed wheels 32 (geared with the wheel 22<1>), and 22 respectively, the wheel 21 being simultaneously disengaged from the wheel 33. In this position the wheels 22, 22<1> are driven in opposite directions.  By means of a worm and pinion system 42, 25, 28, 29, a crank pin 26, mounted on the pinion 29, is caused to rotate in the cam slot of a lever 27 in such a manner as to oscillate the lever 27 about its pivot 53.  This has the effect of bringing the clutch member 30 alternately into engagement with the spring band clutches 43, 31, whereby the shaft 23, on which the clutch member 30 is slidably mounted, is driven alternately in opposite directions.  This alternating motion is transmitted through a series of gear wheels 24 to the shaft 10 of the washing drum.  The change-over to the centrifuging operation is effected by movement of the lever 38, mounted on a shaft 57, by which the shifting lever 41 also mounted on the shaft 57, causes the sleeve 19 to move to the left, as is shown in Fig. 5, so that the toothed wheel 21 and the toothed wheel 33 engage.  During the centrifuging operation, rotary movement is transmitted from the motor 17 or pulley 17<1> through the shaft 8, sleeve 19, wheel 21, and wheel 33 to the drum shaft 10. Some of the gear wheels 24 are mounted eccentrically with respect to a shaft 35 keyed at one end to one of a pair of bevel wheels 40, so that on movement of the lever 38 to the "centrifuging" position, the gear system 24 is thrown out of engagement with the wheel 33 and consequently the wheels 22, 22<1> remain at rest.  A device to attract the attention of the operator is brought into action if it is attempted to move the lever 38 whilst the machine is in motion.

Title: Colour radiography
IPC: G03C5/16
Filed: 1962-03-08
Abstract: 935,050. Making coloured radiographs. AGFA A.G. March 8, 1962 [March 10, 1961], No. 8964/62. Class 98 (1). A method for the production of coloured radiographs consists in using a film comprising two light-sensitive silver halide emulsions on a support, the emulsions being differently sensitized, and containing different colour couplers, in which the film is exposed to form an X-ray image, and then subjected to a further non- imagewise exposure by light to which only one of the emulsion layers is sensitized. After processing, this produces a radiograph consisting of a coloured image on a differently coloured background. The two silver halide emulsions may be coated on opposite sides of the support, or one above the other on the same side. In one example, a support is coated with a panchromatically sensitized silver chloride gelatine emulsion and over this is a further silver bromide gelatine layer which is not additionally sensitized. An X-ray exposure of an object is made, and the exposed material developed. A further diffuse non-imagewise exposure is made with yellow light, followed by a further development. The resulting radiograph shows a yellow dyestuff image, against a cyan background. In a second example, the layers are on opposite sides of the support, and a final magenta image on a cyan background obtained. The constitutions of the various emulsions are specified.

Abstract: 1,016,551. Felt. DUNLOP RUBBER CO Ltd. Feb. 27, 1963 [March 9, 1962], No. 9077/62. Heading D1R. A felt comprises a needled mat of interpenetrated substantially aligned continuous man-made fibres, the interpenetration of the fibres being in the nature of an intermingling in three dimensions produced by laying the crimped continuous manmade fibres under tension and subsequently releasing the tension. Fibres or filaments having a potential crimp may be assembled and the crimp developed in the filaments. As shown, warp sheets 1, 2 of crimped twistless yarns 3 are condensed by lease rods 10 of a regulator 11 and the resultant tow passes around driven rollers 12,13 and spreads as it passes therearound. The tow 4 passes over an arcuate spreading rod 14 or cambered roller and then through a chamber 15 having infra-red heaters 16 to develop the relaxation of the tow so that the yarns intermingle but still remain substantially aligned. The resultant mat 5 passes over a feed apron 17 and is needled by a reciprocating head 18. Take-up rollers 20, 21 together with the apron 17 are driven at a slower speed than the rollers 12,13. Two or webs may be superposed prior to needling and continuous filament yarn, e.g. nylon or polyethylene terephthalate, may be traversed over the surface to produce pattern effects. The mats may be needled on to a base sheet of knitted or woven fabric, e.g. woven cotton or nylon, or of a bonded non-woven felt, or of syntheitc plastic or rubber. Binding agents, e.g. thermoplastic synthetic resins, may be added to the assembly before, during or after needling. Needle-loom carpeting may be produced by applying a binding agent or sheet over the base sheet after needling. The felt may be calendered. In one example, four felts are superposed, moistened with water and pressed on a heated platen press. Specified filaments are rayon, nylon, nylon 66 of trilobal cross-section, polyethylene terephthalate and polypropylene.
