Abstract: 1,003,524. X-ray diffraction apparatus. T. ICHINOKAWA. May 7, 1962 [July 7, 1961], No. 17486/62. Heading H5R. In an X-ray diffraction apparatus having an electron beam which is directed towards a sample to be investigated, an X-ray producing means is interposed between the beam and the sample. As shown, the electron beam is focused by magnetic lenses 3, 4, and passes through an aperture 14 in a cylindrical adapter 8 to strike a thin metal foil 11 mounted therein. The X-rays produced can penetrate the foil, and are formed into a beam by further aperture stops 12, 15. The X-ray beam strikes the sample 7, which is mounted on a disc 6 so that it can be rotated into position for visual inspection through a microscope 10. The diffracted pattern of X- rays reflected by the sample 7 is received on a photographic plate or film 13. If the adapter 8 is removed, the specimen 7 is struck directly by the electron beam, and the X-rays produced can be analysed by a crystal and detector, so as to determine the elements present in the sample. If the adapter is in position, the diffraction pattern enables the structure of the sample to be determined.

Filed: 1968-04-11
Abstract: 1,189,240. Volumetric respirator. L'AIR LIQUIDE SOC. ANON. POUR L'ETUDE ET L'EXPLOlTATION DES PROCEDES GEORGES CLAUDE. 11 April, 1968 [14 April, 1967], No. 17715/68. Heading A5T. A volumetric respirator providing an adjustable ventilation volume and separately regulated inspiration and expiration times comprises an admission chamber 6, a reversal chamber 10 and an intermediate chamber 8 vented to the ambient atmosphere at 9 all with volumes variable by movement of the pistons 2 and 4. Piston 2 carries a sealing member 13 for shutting off the inlet 12, which is connected to a source of pressurised air, and a pipe 7, 31 with a constrictor device 32 leads to the patient. A branch pipe 20 upstream of the constrictor communicates ultimately with the reversal chamber by a passage 17, 27, 11 having a constructor-28 associated with a double-acting, non-return valve comprising a sealing member 18 biassed to prevent flow through the passage 20, 17, 27, 11 by a spring-loaded plate 23 (as in Fig. 2, not shown) but which, in its other position (as in Fig. 1), prevents back flow. In operation, the inspiration time is governed by the constrictor 32 and the expiration time is adjusted by means of constrictors 28 and 30, the latter regulating the rate of venting to the atmosphere of the pressure on the other side of the sealing member 18, i.e. the pressure in the reversal chamber 10. A modified apparatus is described with reference to Figs. 3 and 4 (not shown) which employs two spring-loaded non-return valves (33 and 34) in place of the device shown in Fig. 1 and incorporating conventional associated features including a phase indicator, flow-meter, and expiration collector in addition to a regulated, venturitype, injector operating intermittently to promote the outflow of air to assist the respiring phase, the air supply for the venturi being derived from the pressurised air source in front of the admission chamber and passes through a needle valve which is closed by the downstroke of the piston 4 as it reduces the volume of the reversal chamber. Fig. 5 (not shown) depicts a modified admission-reversal chamber unit comprising two displaceable membranes with an interposed support in place of the sliding pistons shown.

Title: Improvements relating to methods of and means for providing an embossed design upon cloth or the like material
IPC: D06C23/00
Filed: 1928-06-19
Abstract: 317,578. Hudson, G. R. June 19, 1928. Embossing processes.-An embossed pattern is formed on silk, velvet, cloth, or other textile or similar material 20 to resemble appliquÚ, by pressing the desired design into the material and passing steam into a portion of the material which includes the walls 23, Fig. 5, of the design. The material is placed between co-operating moulds 15 18, the countermould 18 having openings corresponding to projecting parts 17 on the mould 15, and a moisture-retaining lamina 21, e.g., of felt, is placed on the countermould 18 so as to contact with the raised parts of the material. Heat and pressure are applied by means such as an electric iron 22 and the material becomes set by the steam generated which acts only on the projecting parts 23 of the material. After the iron 22 and lamina 21 have been removed, a partial vacuum is applied to the face of the material so as to draw out the moisture and raise the design still further. The mould 15 may have openings corresponding to raised parts on the countermould 18, and in this case, hot or cold air may be blown through the co-operating moulds while the material is still between them. Embossing-surfaces.-Either of the moulds 15, 18 may be formed of very flexible material such as rubber or felt, and the coacting mould formed of more rigid material, e.g., leather or linoleum. The parts 17 of the mould 15 may be slightly undercut, as shown, and the countermould 18 shaped correspondingly. Creases may be formed in the material by laying wires across the parts 23 of the material exposed above the countermould 18, or, when suction is applied after the pressure operation, by providing narrow slits in the mould 18. In order to vary the depth of the embossing, the material may be subjected to successive treatment in different moulds, or suitably-shaped pieces may be placed on the exposed parts 23 of the material with corresponding indentations in the parts 17 of the mould 15. A flat plate having an opening to accommodate the countermould 18 may be placed on, or formed integrally with, the mould 15 so as to give the effect of a raised design on a sunken panel. Wedge-shaped pieces co-operating with similarly-shaped recesses in the mould may be used to vary the pattern. Either or both of the moulds may have cloth or other material on its operative surface to absorb moisture. The mould 15 may consist of a pad of rubber, felt, &c., having projecting parts 17 formed by pieces of metal, cardboard, linoleum, or leather secured thereto by rivets.

Filed: 1925-07-14
Abstract: 253,732. Binder, K. July 14, 1925. Developing; fixing. - A daylight developer is prepared by making a red aqueous solution of a complex iron phenol compound and adding excess of alkali. The compound may be derived from a polyvalent phenol such as pyrocatechin (divalent) or pyrogallol (trivalent), e.g. the red salts of tripyro catechin-ferri acid. The free complex di-pyrocatechin-ferri acid or salts thereof may be first converted into red salts bv alkali, and used for the developer with excess of alkali. To prevent discolouration, a soluble sulphite may be added to the developer. Alternatively, the developer may comprise the components forming a red solution of a complex iron pyrogallol salt with excess of alkali, e.g. ferric acetate, pyrogallol, caustic potash, and sodium sulphite. The properties of the developer are largely determined by the alkali used and the excess thereof. The developers have also a desensitizing action. Particular developing formulµ are specified, and also acid fixing baths comprising sodium thiosulphite and sodium bi-sulphite.

Title: Improvements in or relating to electrical pulse communication systems
IPC: H04J3/08
Filed: 1945-07-16
Abstract: 596,051. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. July 16, 1945, No. 18204. Convention date, May 19, 1944. [Class 40 (v)] A communication system including a plurality of stations uses time-modulated pulses between two of the stations, which pass through a third station, and amplitude modulation of the timemodulated pulses is used for communication between the third station and one of the other two. The system may be further multiplexed by the intercalation of several time-modulated channel trains of pulses. In one embodiment, for a single time-modulated channel, a relay and " in and out" branching unit is designed to receive pulses 17, Fig. 2, having both time and amplitude modulation. A decoupling amplifier 18 and low-pass filter 19 yield the wave 21 with which pulses 17 are amplitude modulated. A clipper-amplifier 22 inverts and removes the amplitude modulation from pulses 17 to yield time-modulated pulses 24. If switches 25, 29 are open and switch 35 closed, the pulses 24 are passed to valve 36 where they are further amplitude modulated with a signal 37 from source 38 and pass out of the station as pulses 39. Alternatively, with switch 35 open, and switches 25, 29 closed, the pulses 24 are demodulated at 26 and,fed through low-pass filter 27 to a reproducing device 28. Further time-modulated pulses 30 are produced in modulator 31 fed from a signal source 32 and a wave generator 34 synchronized by pulses 24. The new pulses 30 are fed over switch 29 to valve 36 for amplitude modulation as before. A multi-channel unit is also described, wherein intercalated time and amplitude-modulated pulse trains are received from a radio receiver 53, Fig. 3, or line 51, the pulses of one channel train being of greater duration than those of the others to serve as synchronizing pulses. Gating pulses for the three channels shown are derived from clipper 57, synchronizing channel pulse duration discriminator 58, gating pulse shaper 59 and individual phase-shifters 60, 61, 62 adjusted to pass the gating pulses to channel separators 63, 64, 65, respectively, with the correct phase. Relay units 71, 72, 73, respectively, of the type shown in Fig. 2 are connected to the outputs of units 63, 64, 65 and their outputs are fed to a mixer 74 feeding the outgoing line 75 or radio transmitter 76.
