Abstract: 734,055. Gas-fuelled lighters. BRUDER EISERT AKT.-GES. April 27, 1953 [March 18, 1953], No. 11546/53. Class 75 (3). A gas-fuelled lighter comprising an exchangeable fuel reservoir 1 having a valve with a valve head 9 which is actuated to open or close the gas discharge aperture of the gas channel 4 by the lighter cover 15 bearing on a valve stem 11 projecting from a bore in the burner tip and in which there is provided a supply line 7 leading from the fuel reservoir 1 to the gas channel 4 has a valve part 3 which contains the gas channel 4 and is screwed into the valve body 2 to shut off or throttle the gas between the supply opening of the gas channel 4 and the supply line 7 by pressing on a packing 6 therebetween. A key or spanner 17 freely mounted between inturned lugs 20, 21, Fig. 8, in the lighter casing engages the burner tip 13 so as to screw the tip 13 into or out of the valve body 2 to cover the end of the channel 4 by means of a packing 10 on the valve head 9 or to move the head 9 to a throttling or fully open position. The handle of the spanner 17 projects through a slot 22 in the lighter casing which slot 22 is of such a length to enable the tip 13 to be rotated from the closed to the fully open position. Alternatively the spanner 17 may be fixed in the lighter casing and the replaceable reservoir 1 rotated. The valve 9 is held in the closed position for transit purposes by a screwed cap 14 or when the reservoir is in position in the lighter casing by a resilient cap 16. To prevent the valve 9 sticking to the tip 13 the upper surface of the valve 9 or the adjacent shoulder of the tip 13 is provided with ribs 23, grooves or hubs or alternatively a corrugated ring may be inserted therebetween. As shown in Fig. 9, the ducts 7 are replaced by a slit 29 cut in the bore of the valve body 2 and a metal or similar protection disc 26 is provided beneath the packing 6. In a further modification, Fig. 10 (not shown), the disc 6 is replaced by a resilient ring of natural or synthetic rubber.

Title: Improvements relating to assistants for use in the textile, leather, paper and like industries
Filed: 1935-04-18
Abstract: In the dyeing, washing, finishing, tanning, emulsifying, and similar processes of the textile, leather and paper industries, there is added as an assistant to the treatment liquor, a fatty acid of the soap-forming type (or a salt, amide, arylide, ester or other functional derivative of such acid), containing attached to the methylene group adjacent to the carboxyl group a non-acid hydrophilic residue as follows: <FORM:0455310/IV/1> formul  R and R<1> represent any carbon-containing residue which may itself contain a hydrophilic residue of the above form, and R<1> may also represent hydrogen, and X represents a hydroxyl group or an acid residue.  The oxygen attached to a -carbon atom of the fatty acid may be replaced by sulphur, provided the hydrophilic residue is not thereby given an acid character.  In examples, the ethanolamine derivative produced by reacting a -chlorolauric acid with monoethanolamine with prolonged heating to 100 DEG  C. is used as a wetting agent in mercerizing; a product for similar uses is obtained from a -bromolauric acid and diethanolamine; a strongly-foaming product suitable as a washing and levelling agent is obtained by heating together under reflux pyridine and a -chlorolauric acid; the monoglyceride of b -oxystearic acid obtained by saponifying b -monostearic acid with caustic potash, is used as an emulsifying agent; as a washing agent there is used the acetate of the condensation product of ethylene-diamine and a -bromolauric acid ester; the condensation product of polyethylene diamine and a -monostearic acid ester or the corresponding palmitic acid ester, is used as a wetting agent in alkaline liquors. Specification 337,737, [Class 2 (iii)], is referred to.ALSO:In emulsifying processes of the textile, leather and paper industries, there is added as an assistant to the treatment liquor, a fatty acid of the soap-forming type for a salt, amide, arylide or other functional derivative of such acid), containing attached to the methylene group adjacent to the carboxyl group a non-acid hydrophilic residue as follows: <FORM:0455310/III/1> formulae R and R<1> represent any carbon-containing residue which may itself contain a hydrophilic residue of the above form, and R<1> may also represent hydrogen, and X represents a hydroxyl or an acid residue.

Patent GB-807704-A (GB)
Title: Improvements in or relating to electric cutout switches
IPC: H01H77/04
Filed: 1957-04-12
Abstract: 807,704. Thermal switches; switches retained set and released mechanically. SOC. D'ETUDES ELECTRO MECANIQUES. April 12, 1957 [April 28, 1956], No. 12073/57. Class 38 (5). A switch comprises a current-responsive bimetallic element 5 with a contact 10 at its free end and carried by a movable member 6 which is tiltable and controlled by a spring-biased slidable member 14, a releasable locking connection occurring between the movable member and the slidable member when the switch is closed. Thus, in the Figure the end of an arm 7 of the member 6, which tilts about pivots indicated at 9, is engaged in a recess 20 in a projection 17 of the member 14. When the actuating knob 16 is manually moved to the right, the arm 7 is released from the recess 20 and the projection 17 engages and moves the other arm 8 of the member 6 to tilt the member 6 and open the contacts 10, 11. Under overload conditions, the bimetallic element reverses its curvature to open the contacts 10, 11 and in doing so releases the pressure acting to maintain the arm 7 in the recess 20 so releasing the slidable member 14 for movement to the right under the action of the spring 19. Should the bimetallic element be of the kind which does not resume its initial shape automatically on cooling, the final movement of the member 14 to the right acting through the arm 8 restores the bimetallic element to its original shape, ready for a manual reclosing operation. This final resetting movement may be effected by the spring 19 or manually. Specification 772,526 is referred to.
Patent GB-1382523-A (GB)
Title: Holographic method and apparatus
IPC: G01B9/021
Filed: 1972-03-15
Abstract: 1382523 Testing tyres K VOCKENHUBER and R HAUSER 15 March 1972 12130/72 Heading B7C [Also in Divisions G1 H4 and G2] Changes in the surface structure of an object or differences between two superficially similar objects are investigated by a holographic technique which involves storing a first holographic image pattern, representing a first object or the test object before the change occurs, producing a second similar but not identical pattern, representing a second object or the test object after the change has occurred, effectively superimposing the second on the first (stored) pattern, and scanning and detecting the superposed patterns to develop modulated electrical signals which are analysed so that differences in the patterns may be displayed at different brightness levels as a television picture. By "effectively superimposing" is meant either physically superimposing the second image on the first image stored by a television camera screen or scanning the two images at different times, the video signal obtained from the first scan being stored on video tape and then compared with a video signal generated during the second scan. As shown, light from laser 1 is formed into reference beam 5 and object beam 4 by beam splitting partial reflector 3, the beams having optical system 14, 6. Light reflected from the object 7 is passed through optical system 9 which has an adjustable stop 10. The combined beams are formed as a hologram in the plane of the screen of television camera 12. The arrangement is such that the reference beam appears to come from the centre of optical system 9, and since aperture 10 is adjustable, the spatial frequencies in the hologram can be made to correspond with the camera resolving power. The hologram of the original object 7 is stored by the screen of the camera which is, e.g. a Vidicon. The change in the object occurs or is effected or the object replaced and the resultant hologram superposed on the stored pattern. The video output is analysed by one of three methods, the spatial intensity modulations in the pattern being represented in the video signal by time-base modulations. The signal is analysed and displayed on a TV monitor 15 with (a) less modulated image portions appearing dark and highly modulated bright, by rendering only intensity minima as bright displayed images; (b) the inverse of (a); and, preferably, (c) use of a possibly frequency selective, non-linear amplifier, to differentiate between object characteristics and the general granulation in the beam, and direct conversion of differences in modulation depth into brightness differences. A typical application is examination of a tyre which is inflated resulting in a changed hologram.
