Title: Improvements in or relating to hollow metal rings
IPC: B23K9/028
Filed: 1943-06-09
Abstract: 566,125. Making hollow rings for gaskets or thermostats. HAWORTH, L. June 9, 1943, No. 9295.. [Class 83 (ii)] A hollow ring filled with gas or vapour under' pressure and hermetically sealed to serve as a gasket or joint washer or as a temperature sensitive device for effecting thermostatic control is made by assembling two parts separated in a plane normal to the axis of the ring with a gasgenerating material between them and then welding together along their abutting edges. The ring may be formed by cutting or stamping a flat annular washer from a sheet, pressing to arcuate or semicircular shape and assembling with its edges abutting a similar part or a flat annulus after introducing a substance producing a gas or vapour, e.g. by the action of heat, and the two parts are electrically flash-butt welded along the edges 13. For a temperature-sensitive device distorted axially with change of temperature, a ring of rectangular cross-section may be formed by stamping two parts from a flat plate or machining from the solid and then flash - welded together. Axially - extending flanges 14 are welded to the flat faces at 15 at the mean radius thereof to serve as a means of attachment of the ring. The ring may be used for adjusting the axial clearance between the shrouding of axial flow turbine blades and the adjacent shrouding of the stator blades.

[Class 135] The control rod 23 of the engine governors of the parent Specification is operated from the control cam 20 by a hydraulic relay comprising a slide valve 1 controlling flow of pressure fluid to the cylinder of the piston 2. Movement of the cam moves the sliding bolt 3 and the slide valve 1 linked to it, thus allowing fluid to move the piston 2 until the valve 1 is restored to its initial position. Specification 598,667 is referred to.

Title: Rotary feeding device and method for pressure vessels and the like
IPC: D21C7/06
Filed: 1950-04-17
Abstract: 699,738. Feeding device to pressure vessel. AMERICAN DEFIBRATOR, Inc. April 17, 1950. [April 21, 1949] No. 9376/50. Class 78(i.). Pulp material (Figs. 1, 2) is fed into pressure vessel 10 bv rotor 13, driven through sprocket 47 and enclosed by housing 14 resiliently mounted on the pressure vessel. Packing rings 19 are held by glands 20. As the rotor rotates anticlockwise, pulp falls into pocket 30, and the rotor is scraped by scraper 31, is injected with chemicals at 34, and then discharges into vessel 10, the discharge being aided by the respective steam jet 35, the conduit of the jet being formed in the rotor 13 and co-operating with aperture 43 of steam chamber 43 at the required moment during rotation. The steam which enters the pocket 30 from vessel 10 is discharged through pipe 45 later in the rotation. Housing 14 is resiliently held by spring bolts 22. Pipes 46 lubricate the rotor and bar 32 is adjustable at 33 to allow for wear of rotor. Housing 14 may be split and the two parts thereof may be held together by bolts, there being adjustable side supports to limit the spacing between the two parts. Pulp (Fig. 5) is fed into hopper 60 and passes down into funnel 61, whence it is delivered to pocket 30 of rotor 13 by screw 69. This delivery is assisted pneumatically, the compressed air carried in a pocket after material discharge passing away through pipe 45 (see above), and aspirating air through pipe 67 from the bottom of hopper 6] through holes 72, and injecting air into hopper 60 through jet 66. Specification 393,159, [Group VIII], is referred to.

Title: Improvements in antenna systems for wireless communication
IPC: H01Q1/52
Filed: 1922-04-01
Abstract: 197,492. Robinson, E. Y. April 1, 1922. Aerials.-In order to reduce induction losses and to Jeesen the difficulty of effective insulation, the supporting. members of the antennae are made highly conductive and are fed with separate currents of the same frequency and phase as those flowing in the aerial itself. As shown in Fig. 8, the aerial 1 is supported by three masts or girders 4, and has a central down lead 2. Each mast is tuned into resonance with the aerial system, and is supplied through loading coils 14 with current which sets the masts oscillating in synchronism with the aerial 1. As shown, the masts are mounted on insulating blocks 13 shunted by separate coils 14. The coils 14 may, however, be connected to a common earth lead, and the system energized as a whole, thus dispensing with the usual down lead 2. Preferably the whole system is designed to be operated at its " natural " unloaded frequency. Each mast may be so designed as to have the desired natural frequency: or it may be loaded either by means of laminated rings 10, Fig. 4, supported by 'brackets 11 and shunted by a tuning condenser 12, or by sbeel rings 10, Fig. 6, interlinked with a secondary coil 15 containing variable inductance 16. The highly in. ductive portions of the mast may be shunted by a tuning condenser as in Fig. 4, and the tuning of the several masts may be conveniently effected by remote control switches. The masts may be divided into insulated segments, the breaks being shunted by highly-inductive loading-coils. Instead of supplying the masts directly with power. they may be coupled inductively or capacitatinelyto the antennae. system either at the top or through points which are at equal potentials. If the voltage drop along the mast is arranged to equal the voltages induced in the antennae, no insulation is necessary; in any case the potential differences may be made relatively small. When supporting-gaps are used, these must be insulated from the mast; or the gaps may be broken up into insulated segments and graded electrically, for example by shunting the insulating gaps with suitable condensers. Alternatively, the gaps 19, Fig. 8, may be tuned by means of loading-coils 20 and energized similarly to the masts. Under these circumstances, similar points on the whole system will be at the same potential, and the erection may thus be strengthened by the use of ordinary triatics. As shown in Fig. 8, three triatics 17 support a triangular antenna network 1, whilst the three masts are bound together at various horizontal distances by other triatics 18, thus reducing the number of guys 19 to three per mast.

Filed: 1995-10-19
Abstract: A method of and apparatus (Fig. 4) for recording an information signal (Vi), in particular an EFM-modulated signal, are revealed, which information signal comprises time-code signals which alternate with first time-synchronisation signals. The record carrier (1) which is employed is provided with a preformed servo track (4) which exhibits a periodic track modulation whose frequency is modulated in conformity with the position-information signal (Fig. 2). The position-information signal (Fig. 2) comprises position-code signals (12) which alternate with position-synchronisation signals (11). During recording a fixed phase relationship between the time-synchronisation signals and the position-synchronisation signals (11) is maintained, so that the portion (141) of the servo track (4) in which the time-synchronisation signals are recorded are situated at fixed positions relative to the servo-track portions (140) which represent the position-synchronisation signals (11).
