Title: Improvements in or relating to cylinder covers for internal combustion engines
IPC: B23K1/00
Filed: 1930-01-13
Abstract: 334,481. Allgemeine Elektricitõts- Ges. Jan. 17, 1929, [Convention date]. Engine cylinders. - A cylinder head is formed of a number of simple rolled or pressed parts which are connected together by hard soldering. The head shown comprises tubular parts a, h, i, flat discs b, c and shrunk- or rings d, k; wrought iron, steel or copper may be used; the disc b, which may be integral with the part a, is thin and supported by radiating partitions g having staggered holes x for the circulating water. The soldering process is effected by placing a suitable metal-e.g., copper -near the surfaces to be joined, which are pressed together and heated in a reducing atmosphere to a temperature not below 1000‹ C.; the solder is thus drawn into the joint by capillary action; after cooling the ring k is removed. Any excess of soldering material is volatilized to form a protective layer on the interior of the water space in the head.

Title: Cylindrical electromechanical transducer
IPC: H04R15/00
Filed: 1967-01-11
Abstract: 1,121,374. Magnetostrictive vibrators. WESTINGHOUSE ELECTRIC CORP. 11 Jan., 1967 [15 March, 1966], No. 1533/67. Heading H2A. An electromechanical transducer comprises a hollow cylinder having longitudinally-extending grooves formed in one of its cylindrical surfaces, an array of thin annular magnetostric - tive elements arranged coaxially with the cylinder in vibrative coupling to the grooved surface, and an energizing coil toroidally wound around the array, the turns of the coils being accommodated in the grooves of the cylinder. As shown, a stack 15 of annular laminations of nickel is located inside a stainless steel cylinder 12 and secured to it preferably with epoxy resin. The cylinder 12 has longitudinal grooves 21 which accommodate the turns of a toroidal winding 20. When the winding is energized appropriately, cylinder 12 vibrates in a radial mode, such vibrations being imparted to a material or fluid in contact with the outer surface of cylinder 12. Where the vibration is to be mparted to a medium located within the assembly, the cylinder 12 lies within the stack of laminations and is grooved externally (Fig. 3 not shown). For acoustic impedance matching, a number of arrays of stacked laminations, spaced vertically, are embraced by a single winding, and a grooved cylinder lies within them (Fig. 4, not shown). The laminations are preferably 5 mils thick. The cylinder wall may be relatively thin (e.g.  inch) to prevent thermal stresses. The assembly may be cooled to keep the temperature of the laminations low during operation in order to avoid development of thermal stresses.

Title: Improvements in or relating to electric signalling systems
IPC: H04L27/08
Filed: 1934-01-16
Abstract: 423,824. Code telegraphy. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and ESPLEY, D. C., c /o General Electric Co., Wembley, Middlesex. Jan. 16, 1934, No. 1593. [Class 40 (iii)] In a relay for signal impulses of D.C. or rectified A.C. type, the input current passes through both the operative winding 8 and the restoring winding 9, and impedances such as the condenser 10 are so arranged that the armature responds to the differential action of the two windings. The object is to eliminate residual bias depending on the values of signal-amplitude and battery-voltage, and to impart an initial marking bias which gradually dies away during a series of signals and is opposite to the spacing bias acquired from magnetic remanence during a long spacing period of rest. Impulse trains a, Fig. 2, are rectified by the valve 5, Fig. 1, and current of carrier frequency is shunted away through the small condenser 6. The operating coil 8 takes the whole of the remaining anode current 11, Fig. 2, but the restoring coil takes only that part 12 which is not shunted through condenser 10. The effective current is the difference c, Fig. 2. Inductance in the relay would round off the peaks of these curves. In modifications, the coils 8, 9 may be fed through valves controlled from potentiometer resistances connected in the places occupied by the coils in Fig. 1 ; the relay may comprise an additional biassing co ilgiving a constant restoring-tendency, Fig. 3, (not shown) ; and the effect of the condenser 10 may be produced by an inductance differently arranged, Fig. 4, (not shown).

Title: Improvements in the mechanism of gramophones and the like
IPC: G11B17/16
Filed: 1919-07-18
Abstract: 141,646. Gilbody, F. H. July 18, 1919. Multiple record machines.-Gramophones are adapted to play a series of records in succession by arranging the records in sloping compartments in the upper part of a record magazine from which they slide in turn on to the turntable. After reproducton, the record is lifted at one side of the turntable, and the continued movement of the latter swings the record back towards the lower part of the magazine. In falling therein it strikes a tappet which serves to deliver the next record of the series on to the turntable. Fig. 2 is an elevation showing the record magazine in section, Fig. 3 is a side view of the magazine, and Figs. 5 and 6 show the device for raising the record prior to its removal from the turntable. The upper part of the record magazine U has at each side a series of sloping ledges V on which the records are supported, being inserted through slots W. Slides Y forming extensions of the lowest ledges V extend on each side of the turntable A, and are cut away so that a record on arriving in correct position may fall through gaps in the slides on to the turntable. When a record has been played, the tone-arm is raised and returned to starting- position by the mechanism described in Specification 136,730. During this return movement a pin on the tone-arm displaces a spring-controlled slide 1 which lies beneath the overhanging edge of the record on the turntable. A bevel on the upper surface of the slide tilts the record, and as its opposite edge is still in contact with the rotating turntable, the record is swung towards the magazine U and falls into the lower compartment thereof. In falling, the record strikes the end of a lever 5, and by means of a rod 6 steps a ratchet wheel Z round one tooth, thus raising the stop arm X and allowing the lowest record to slide down the guides V, Y on to the turntable. The sound-box is then replaced in the starting-groove of the new record by the means described in the above-mentioned prior Specification.

Abstract: 588,770. Measuring torque. SHEPHERD. G. R. (Westiughouse Electric International Co.). Jan. 26, 1945, No. 2133. [Class 40 (i)] [Also in Group XIX] Apparatus for indicating the torque of a shaft comprises a pair of axially displaced elements, torsionally resilient means interconnecting said elements providing freedom for relative angular displacement thereof and preventing relative tilting thereof, axially resilient means supporting said elements on said shaft whereby said elements may move axially relative to said shaft thus compensating for unequal shortening of said shaft and said torsionally resilient means when said shaft is torsionally deflected, and means for measuring the relative angular displacement of said elements upon torsional deflection of said shaft whereby the torque of said shaft is indicated. As shown in Figs. 2 and 3 the apparatus comprises two axially split torque rings 3 and 5 axially spaced along a shaft 1 and clamped thereto on axially split support rings 11 and 13 by means of bolts 15. The confronting faces of the torque rings 3 and 5 are interconnected by means of flat strip-like members 17 equally spaced about the circumference of the torque rings 3 and 5. These radial vanes 17 serve to maintain the spacing of the torque rings 3 and 5 and also to provide stiffness against lateral bending of the torque rings and at the same time allow torsional flexibility between the torque rings. The confronting axial faces of each of the torque rings are provided with axially extending interlocking but not touching pads 18, 19, 20 and 21 to which magnetic strain gauges 2 are secured. The magnetic strain gauges 2 each comprise a pair of E-shaped laminated iron core members 22 disposed in confronting relation. and each of Which has a coil 23 wound about the central leg. A laminated iron armature 24 is disposed between the confronting faces of the core members so that small air gaps 25, 26 are formed on each side thereof.
