Abstract: 767,566. Ion trapping in cathode ray tubes. NEILL & CO. (SHEFFIELD), Ltd., J. May 17, 1954 [June 11, 1953], No. 16085/53. Class 39(1). An ion trap magnet comprises a permanent magnet ring with diametrically opposite poles mounted on the neck of a cathode ray tube by a resilient support secured to the magnet ring by end engagement therewith and forming a resilient bridge between the inner edge of the magnet and the neck of the cathode ray tube neck. In one form, Fig. 2, a permanently magnetized ring 10 with diametrically opposite poles is carried by a rubber grommet 12. The assembly is pushed to its approximate position and then pushed slightly in the reverse direction so that the tapered ends of the grommet are flexed in opposite directions and grip the tube neck 11 firmly, while allowing rotation about the tube axis. In modifications the U-shaped sectioned grommet may face outwardly, Figs. 4, 5 (not shown) or may be replaced by three or more short lengths of U-sectioned rubber evenly spaced around the tube neck, the lengths being preferably cemented to the magnet ring. In another form, Fig. 8, the magnet ring 10 is held on the tube neck by a spring strip 19 of polygonal shape having holes 20 at the corners of the polygon so that the magnet ring is located in the holes at the corners. The strip 19 is sprung on to the tube neck. In further forms the resilient support may extend around the whole or major part of the ring circumference and may be (a) a flat ring of rubber, plastic or felt secured by adhesive or a clip or clips to one side of the magnet ring, or (b) as shown in the drawings with the rubber replaced by plastic. Axial as well as circumferential adjustment is possible. The magnet ring may be of " Alni " or " Alnico " alloy and is formed by casting. The position of one or both poles of the magnet can be marked on the magnet ring or on the resilient mounting. Prior art devices comprising two bowed steel strip pole pieces clamped at one end to a permanent magnet, so that the device can be clipped on to the cathode ray tube, are referred to. In such devices the assembly is secured in position by a clamping screw connecting the free ends of the strips or the free ends of a separate strip carried inside the pole piece strips, non-metallic sleeves covering the ports which grip the tube neck.

Title: Processes for the manufacture of thermosetting resins
IPC: C08J3/16
Filed: 1971-05-21
Abstract: 1347878 Phenoplast resin beads SAINTGOBAIN 21 May 1971 [22 July 1970] 16302/71 Heading C3R Beads of a thermosetting phenoplast resin are prepared by condensing phenol or a phenol derivative with formaldehyde in the presence of a catalyst which is an organic or inorganic base, in an aqueous medium and in a homogeneous phase, whereby a resin is obtained in the form of a suspension of oily droplets in the water, the equilibrium of which is maintained by stirring, the suspension being stabilized by the addition of a dispersing agent which prevents the coalescence of the droplets. The dispersing agent is preferably a combination of a surface active agent, e.g. an alkaline alkylarylsulphonate, and a protective colloid, e.g. a carboxymethyl cellulose or a polyethylene glycol. Suitable catalysts are NH 3 , ethylene diamine, diethylene triamine, hexamethylenediamine or -tetramine. Preferably a fusibility agent is incorporated into the initial reaction mixture to render the resulting resin insoluble before its degree of cross-linking has rendered it infusible. Such agent may be a primary or secondary aliphatic, aromatic or alicyclic amine, e.g. hydrated hydrazine, the compound obtained by reacting hydrazine with HCHO, piperazine, piperidine and dicyandiamide; melamine, aniline and urea. The reaction temperature may range from 30-110‹ C. The suspension formed may be progressively cooled to room temperature whilst stirring. In the examples phenol is reacted with HCHO using as fusibility agent and catalyst respectively; (i) none, NH 3 ; (ii) aniline, ethylenediamine, (iii) melamine, NH 3 ; (iv) urea, NH 3 , the dispersing agent being in all cases sodium dodecylbenzene sulphonate and carboxymethyl cellulose. Uses.-In paints, varnishes, injection moulding, coating textiles or paper, brake linings, abrasive wheels, board, enamelling, concrete and in binding mineral or organic fibre felts.

Abstract: 460,623. Valve generating circuits; thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. June 12, 1936, No. 16505. Convention date, July 25, 1935. [Classes 39 (i) and 40 (v)] Two electrode systems in the same envelope are connected to form two short-wave oscillation generators of different types, the output electrodes being coupled to a common output circuit and arranged to oscillate in phase opposition. In the circuit shown in Fig. 2, plane grids and plates are provided on each side of a plane cathode consisting of parallel wires. On one side the grid is negative and the plate positive ; on the other side the plate is negative and the grid positive. A tuned circuit is connected between each plate and the opposite grid, the coils 21, 25 being tapped for connection to the respective batteries 22, 26. The coil 25 may be coupled to the load circuit 28. One set of electrodes is stated to function as a Barkhausen-Kurz oscillator, the other as a negative-grid oscillator. In a modification, Fig. 3 (not shown) each tuned circuit is replaced by a pair of Lecher wires tuned by short-circuiting bridges to which the supply batteries are connected. In another modification shown in Fig. 7, the electrode systems form a diode oscillator and a negativegrid oscillator respectively. An anode 46 is connected through a tuned output circuit 52 and a battery 26 to the cathode 35. A negative grid 44 situated between the cathode and the anode 46 is associated by a tunable Lecher-wire pair 50 with a second anode 36 on the opposite side of the cathode and connected to the anode 46 by a conductor 49 having sufficient inductance to cause the potentials on the anodes to be in anti-phase. Fig. 5 shows a construction of the valve used in Fig. 7. An indirectly-heated rod cathode 35 and a parallel rod-anode 36 are placed within an oval grid 44, supported by a flanged bracket 43 and lead-in rod 41. The anode 46 is semi-cylindrical and partially surrounds the grid 44 at the end nearest the cathode 35. It is supported by a rod 48 attached to a flange 47. In another form of valve, Fig. 6, a rod anode 55 and two cathodes 56, 57 form a double-diode oscillator, a grid 58 surrounds these electrodes, and two semicylindrical anodes 61, 62 surround the grid at the parts adjacent the cathodes, forming a pair of negative-grid oscillators.
