Abstract: 458,836. Refrigerating. EWART, J. H., HAWES, W. B., and EWART & SON, Ltd., 346, Euston Road, London. June 20, 1935, Nos. 17768/35 and 17361/36 (divided out of 459,051). [Class 29] Absorption systems.-In a continuouscycle system with inert gas circulating by gravity between the absorber 4 and evaporator 3, a portion only of the inert gas is circulated through the evaporator, the other portion being byepassed. The inert gas (hydrogen) rises from the absorber through a conduit 23, is heated by hot vapour from the generator 1 in a vertical exchanger 24, 19, cooled in a conduit 25, and then delivered through a nozzle 26 to induce a flow of mixed vapour and hydrogen from the upper part of the evaporator, where it is in counterflow to the liquefied refrigerant supplied from the condenser 2 through a U-seal pipe 22. The generator comprises pipes 5 connected between headers 6, 7, located in a heated flue 9. The mixture of evolved vapour and liquid from the upper header passes into a centrifugal separator 10, whence the vapour passes to the condenser and liquid to a sump 15, and a further pipe 16 rising through the flue. This riser is connected with another separator 17 whence the vapour passes through the exchanger pipe 19 back to the first separator 10 and liquid to a pipe 21 of the usual liquor heatexchanger between the absorber and the generator. The evaporator and absorber may be of tubular form instead of the drum form shown.

Filed: 1920-07-02
Abstract: 145,735. Krupp Akt.-Ges., F. March 9, 1918, [Convention date]. Sights.-Relates to sighting-apparatus in which the line of sight is independent for training, the azimuthal position of the sight being controlled by differential gear operated by two independent mechanisms, one of which moves the sight alone while the other causes the sight to remain stationary when the gun is trained. According to the invention, the azimuthal position of the sight is determined by a guide disk controlled through differential gear by the two independent mechanisms. In the construction shown, the sight J' is carried by a ring J rotating on vertical pivots i<1> on a casing H which is rotatable about an axis parallel to the trunnions on a bearing c<2>, c<3> carried by a part of the carriage which partakes of the training movements of the gun. The casing H is rotated to elevate the sight by a worm K, the tangent elevation being read, through ' an aperture h<2> in the casing H, on a drum G<2> geared to one of the trunnions. The ring J has horizontal studs N, Fig. 4, projecting inwards through slots in the side walls of the casing H and engaging a circular groove in the periphery of a guide-disk M. The disk M is mounted on a vertical pivot c<8> carried by an extension c<4> of the fixed bearing bracket c<2>, c<3>. The azimuthal position of the disk is controlled by differential gear S operated firstly by a hand-wheel T<1>, and secondly by the training-gear of the gun, the arrangement being such that, when the gun is trained, the disk is turned through the same angle in the opposite direction. The angle through which the ring J is turned about its pivots i' is indicated by a disk N, Fig. 4, carried by one of the studs N, which is rotated by a bevel wheel engaging a rack formed on the edge of the slot in the casing H.

Filed: 1937-06-30
Abstract: 494,365. Television. FARNSWORTH TELEVISION, Inc. June 30, 1937, No. 18151. Convention date, July 18, 1936. [Class 40 (iii)] A plurality of identical images of a continuously moving film are scanned in turn by a two-dimensional scanning device, the linear spacing of the images being such that each film frame is scanned a plurality of times. The film 2, Fig. 1, is projected as two images through prisms 6, 6<1>, onto the screen 21 of a dissector tube, a shutter 22 occulting each image in turn ; each image is scanned in turn, the frame component of scanning being due to the combined effect of the film movement and the frame deflecting coils 29 ; thus, if the film gate is as long as a film frame, and the two images overlap by one half frame, each film frame is scanned twice. For interlaced scanning, the line frequency is such as to give an odd number of lines for a complete scan, or the two images may overlap by one half frame Œ one line, or the frame deflecting oscillation 36, Fig. 2, may be modified by adding a component 35 as disclosed in Specification 459,400. Where the film is traversed at 24 frames/sec. and the scanning is at 60 frames/sec., five prisms 41 .... 45, Fig. 5, producing five images are used in conjunction with a disc, Fig. 7, which occults all but one ; the outer prisms are made wider than prisms 42, 44 and 45 to ensure that the images are of equal intensity ; the film gate is one and two-fifths of a frame in height, and every other film frame is scanned twice, intermediate frames being scanned thrice. Where this is undesirable, prism 42 is replaced by two prisms which superpose images of adjacent films, each image being of half intensity. Interlacing may be obtained as described above. The Specification gives formulae for the length of the gate for the general case. Specifications 368,309 and 368,721 also are referred to.

Abstract: 167,747. Nouvel, P. Aug. 12, 1920, [Convention date]. Electromagnetic switches; ratchet actuation; contacts.-A distant control electromagnetio switch comprises an ironclad solenoid 10 energized from any number of points at a distance and serving to raise a core 13 on which is centrally pivoted at 22, for self-aligning movement in a vertical plane, a bridging contact-member 20 co-operating with a pair of fixed contacts 3. The core carries upper and lower transverse pins 17, 18 which engage with upper and lower ratchet teeth 15, 16 in a fixed tube 14 surrounding the core and produce a one-way rotational movement of the core and its contact-member when the core is lifted and lowered. When the core is raised by the energization of the solenoid on the closure of one of the distant switches, the contact-member is lifted from its contacts and rotated, by the engagement of the pin 18 with one of the teeth 16, through half a right-angle. When the core descends on the release of the distant switch the contact-member rotates through a further half right-angle in the same direction owing to the engagement of the pin 17 with the teeth 15. The contact-member is now in the ' off ' position, and on a further closure and release of the distant switch it is brought to the ' on ' position. Mercury cup contacts may be used instead of the contacts 3.
