Abstract: 765,127. Induction relays. ENGLISH ELECTRIC, CO., Ltd. Sept. 23, 1955 [Oct. 1, 1954], No. 28338/54. Class 38(5) A relay coil is adjustably mounted on its core to vary its linkage with the leakage flux and thus permit adjustment of 'the relay operating characteristic. As shown, the coil 25 of a time-overcurrent induction disc relay is axially movable on the core part 24a and fixed in its adjusted position by bolts 27 passing through the core and slotted extensions 26 of the coil. The core has a slot 24b to promote the leakage flux denoted by the arrow. In another construction (see the drawing accompanying the Provisional Specification, not shown), the coil has a bore larger in one dimension than the core part which it embraces, whereby the coil may be adjusted in a lateral direction relatively to the core.

Title: Improvements in sound films and recording processes and apparatus therefor
IPC: G11B7/00
Filed: 1937-10-19
Abstract: 496,424. Electro-optical sound recording. KOLB, O. K. (Poulsen, A., and Peterson, A. C. G.) October 19, .1937, No. 28439. [Class 40 (ii)] In apparatus, such as described in Specification 485,469, for recording sound on film having multiple variable area tracks of the push-pull type, utilizing two similar modulating devices such as oscillographs 2, 3, Fig. 2, one terminal of each device is connected to a common terminal of a source of speech modulated current such as a transformer 13, their other terminals being connected each in series with a condenser 15, 16 to a second terminal of the current source 13. The junctions of the oscillographs with the individual condensers are respectively connected to the poles of a source of biassing current for the purpose of producing a noiseless record. A choke 14 may be inserted in order to isolate the phonic currents from the source of biassing current. The oscillographs vibrate 180‹ out of phase with each other and so can be made to produce a push-pull record. In a recording system light from a source 1, Fig. 1, is passed through a triangular aperture 7 to two mirror oscillographs 2, 3. The two images of the aperture 7 are focused by a lens 4 on a screen 8 bearing a slit 9. The widths of the two beams passing through the slit 9 depend on the positions of the images relative to the slit and the sound track is obtained by focusing the beams transmitted bv the slit 9 on the film 10 by lenses 11, 12.

Abstract: 738,937. Coiling strip. LOEWY ENGINEERING CO., Ltd. Oct. 16, 1953, No. 28599/53. Class 83 (4). A coiler for metal strip comprises a drum on to which the strip is coiled and a number of guiding and forming rollers grouped around the drum and linked together to form a flexible roller chain which can envelope the drum when brought close to the latter and can be retracted as a whole into an inoperative position away from the drum by means attached to the opposite ends of the roller chain. Guiding and forming rollers 17, loosely mounted on axles 18, are spaced around a collapsible coiler drum 13 as described in Specification 738,387 to which reference is made, and are connected together by links 20 at each end of the axles 18 to form a flexible roller chain. This chain is moved from an inoperative position in which it rests on a curved tray 36 to a position in which, during the initial coiling, it closely encircles the drum 13, by link means 31, 32 actuated by fluid-pressure means 25 and by fluid-pressure means 34, attached to its ends. The central roller 17 is guided in this movement by a radial guide 35. Each roller 17 has a reduced end 171 which rolls on a flange 19 on the coiler drum 13 to rotate the rollers 17 at a slightly higher peripheral speed than that of the drum, a roller 23 loosely mounted on the axle 18 at the other end of the roller 17 being supported by an extension 121 of the drum 13. Strip is fed to the coiler through a channel 38 having a pivoted cover carrying a flanged guiding roller 43 and swung by fluid actuated means 39, the roller 43 also serving to flatten out the tail end of the strip.

Abstract: 364,152. Varying the lift of aircraft and draught of watercraft. DAVIES, H. R., 558, Wyndham Road, Teaneck, New Jersey, U.S.A. Sept. 30, 1930, No. 29262. Convention date, Oct. 3, 1929. [Classes 4 and 113 (ii).] For varying the lift of an aeroplane, a rotating cylinder or other body driven by an air-turbine so as to utilize the Magnus effect and modify the airflow over the main wing is mounted so that it can be moved from an ineffective position within the wing to a position above or below the wing. Similar rotating cylinders may be projected from the sides of watercraft beneath the waterline to diminish the draught by raising the vessel. A cylinder 26 with discs at its ends is mounted on a spindle 28 carried by links 30 hinged to the front spar of the wing, and is raised and lowered through a spring- controlled door 38 in the wing by screwed links 32 which pass through nuts 33 having pulleys 34 turned by bands 35 from a hand-wheel near the pilot's seat. A modification is described in which a pair of such cylinders is projected below the wing when it is required to increase the lift. The turbine drive for the cylinder is shown in Fig. 6, and comprises a ring 67 carrying blades 68, the ring having one fixed and one removable flange carrying planet rollers 70, 73. These rollers co-operate with treads 76 carried by a disc 65 keved to the shaft 28, and with the ends of the cylinder elements 26, so that the cylinder elements are driven at a greater speed than the air-turbine.

In a paramagnetic gas analysing apparatus of the type in which a non-uniform magnetic field moved cyclically across a hot-cold gas junction produces pressure pulses in the gas which are then applied to the diaphragm of a transducer to produce an electric signal, the gas under test is fed through two parallel connected opposed arcuate paths 67, 68, Fig. 1 having a centre of revolution common with the axis of a rotary magnet 53 providing two substantially identical symmetrically disposed magnetic fields of non uniform distribution and separate diametrically opposite parts of the arcs B, C; A, D; are made hot and cold respectively so that pressure pulses resulting from rotation of the magnet are applied to the diaphragm 37 of the transducer in push-pull. The paths are made of a conductor of high resistivity such as stainless steel or nichrome and are heated by the passage through them of an electric current, blocks of conductive metal being attached to opposite points on the arc to short circuit the parts of the path to which they are attached, to conduct away heat, and to create in the gas four hot-cold junctions. Adjustable orifices in the system insure equal gas flow in the three paths and substantially equal resistance paths to the two sides of the diaphragm. Specification 685,920 is referred to.

The subject-matter of this Specification differs from that of Specification 698,033 in that the receiver of the synchronous transmission between the directional gyro and the rate of turn gyro has a three-phase rotor. An electromagnet which is energized through a contact on the steering hand wheel during straight flight holds the rotor in a fixed position and couples one phase of its output to a circuit biasing the rate of turn gyro to maintain a predetermined course. Upon operation of the hand wheel to initiate a turn, however, deenergization of the electromagnet frees the rotor, disconnects the rotor from the biasing circuit of the rate of turn gyro, and so energizes all the windings of the rotor from a single phase A.C. source that the rotor is driven by its stator into positional correspondence with the heading of the craft, without ambiguity, in readiness for maintenance of a new straight course. Specifications 698,032 and 698,037 also are referred to.
