Title: Improvements in high pressure apparatus
IPC: B01J3/06
Filed: 1962-12-19
Abstract: 1,023,449. Very high pressure apparatus. ALLMANNA SVENSKA ELEKTRISKA A.B. Dec. 19, 1962 [Dec. 27, 1961], No. 47873/62. Heading B1X. A very high pressure apparatus suitable for the production of diamonds by compression of a graphite/metal charge comprises a reaction chamber defined by two end surfaces and side surfaces and having an axis of symmetry passing through said end surfaces ; said side surfaces being the inner faces of pressure-transmitting blocks having gaps therebetween, said blocks moving axially in an outer pressureresisting means and being simultaneously constrained by said means to move inwardly ; said end surfaces being the faces of pressure resisting means which are sealed to said blocks and move along the axis so as to follow the axial movement of said blocks. In Fig. 1 (and Fig. 2, not shown), the pressure chamber comprises five sector-shaped blocks 10 of conical outside section having gaps 12 between them and being lubricated along the interface 22 by graphite, molybdenum disulphide or oil, which blocks surround the material to be compressed. The material 33 to be compressed is enclosed in the cylindrical gap formed by the inwardly facing surfaces 16 of the conical segments 10 (11). The ring 58 contacts faces 49 of the blocks 10 causing them to be forced upwards and inwards as a result of wedge action within the casing, compressing material 33 to the desired degree. An opposing member 17 sliding within retaining ring 23 and having disposed between it and an end stop 26 a fluid medium such as oil or water serves to control and contain the pressure around material 33, by means of valve 28. Sealing means 43 serve to contain the material charge within the pressure chamber. The material 33 may be heated by passing a current therethrough when conductive, or by tubes, discs, threads, spirals or other bodies of electric resistance material embedded in the reaction mixture, current being supplied via conduit 44 to the piston 18 and led away via the piston 17 and a cable 45 arranged in a channel 46 in the casing 21. Pressures of several tens of thousands of atmospheres and temperatures in the range 0-2000 ‹C. or greater are envisaged. The materials used for the different parts of the apparatus are mentioned. The embodiment illustrated in Fig. 6 (not shown) is similar to that of Fig. 1 but the lower piston 18 is arranged in the same way as the upper piston 17, thereby enabling the piston 18 to be controlled independently of the movement of the block 10, by suitable adjustment of the pressure control valve 56.

Abstract: 1530918 Electromagnetic damping; bearings TELDIX GmbH 21 Nov 1975 [6 Dec 1974] 48052/75 Headings F2S and F2A [Also in Division B7] A contact-free bearing for a centrifuge rotor or rail vehicle suspension (not shown) is provided with a damper controlled by a sensor to become operative only when oscillations of the rotor or vehicle exceed a predetermined amplitude. Examples are given of electromagnetic damping of active or passive (Fig. 2, not shown) magnetic bearings. As shown, a rotor 1 of ferromagnetic material is supported both axially and radially by coils 4 and 5 which are controlled by sensors 6 and 7. The damper comprises a winding 15 in a ferromagnetic component 16 with pole rings 17, 18, and a ferromagnetic disc 19 on the rotor 1. The damper is activated by a sensor consisting of a permanent magnet 11 and an inductive coil 10, via a threshold value stage 13 which only passes on the signal if the amplitude of axial vibrations is above a certain value. In the application to a vehicle suspension, the bearing may be provided by an electrodynamic rather than an electromagnetic force.

Abstract: 1,116,712. Security systems. RADARGUARD SECURITY Ltd. 5 March, 1965 [5 Dec., 1963], No. 48119/63. Heading G4H. Actuation of an alarm at a protected location causes a radio transmitter to transmit the identity of the protected location to a monitoring station, the transmission comprising a carrier which is frequency modulated with a plurality of sub-carrier frequencies which are themselves amplitude modulated by a combination of identification tones, unique for that particular location. The monitoring station includes suitable filters and decoding matrices to provide a visual indication of the calling location by lighting an appropriate lamp. The carrier frequency and the frequency of the local oscillator at the monitoring station may be swept through a given frequency band at different rates as a precaution against jamming. The monitoring station also includes means for interrogating each protected location in groups of five, those locations in which the protection facilities are " on," e.g. after the staff have locked up, replying with the identity transmission and a test tone. The monitoring station has lamps to indicate that the location has responded to the interrogation. The protection facility " on " or " off response is compared with the setting of a corresponding switch on the control panel and an alarm is given if there is disagreement.
