Patent GB-350513-A (GB)
Abstract: 350,513. Valve amplifying circuits. COURSEY, P. R., 67, Queen's Road, Richmond, Surrey. Feb. 14, 1930, No. 3021. [Class 40 (v).] An intervalve coupling in a thermonic amplifier comprises two rejector circuits tuned to the same frequency, one being in series with the anode circuit and the other in series between the same anode circuit and the grid of the succeeding stage ; one or both of rejector circuits being shunted by piezo-electric, magneto-strictive or like devices which damp the rejector action at a desired frequency. The Figure shows a screened intervalve coupling S3 comprising a rejector circuit L2, C2 tuned to the same frequency band as the anode circuit L1, Cl of the preceding valve. The rejector action of the circuit is nullified at a single frequency or over a very narrow frequency band by a piezoelectric crystal X shunted across the coupling, so that selectivity is obtained without employing lowloss circuits with correspondingly low decrement. Crystals X1, X2 may be shunted across the anode circuit L1, C1 and may have different natural frequencies in order to give sharply defined cut-off frequencies ; the crystal X in this case is preferably arranged to pass a frequency intermediate between these cut-off frequencies. Magnetostrictive or other elements responsive to a single frequency may be used in place of the piezo-electric elements. Transformer coupling in conjunction with the unit S3 may also be used.

Title: Improvements in or relating to electron discharge devices
Inventor: CASSMAN HARRY
IPC: H01J29/02
Filed: 1957-11-12
Abstract: 902,090. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 28, 1958 [Nov. 12, 1957 ; April 24, 1958], Nos. 35142/57 and 13020/58. Class 39 (1). A photo-emissive mosaic 3, Fig. 1, has a transparent secondary emissive electrode 11, facing parallel to it, the mosaic being scanned by a light spot from source 16 which passes through electrode 11, means being provided for directing photo-electrons from the mosaic on to the electrode 11, and for the collection of the secondary electrons which it emits. As shown, an image is projected through window 5 on to transparent photo-electric layer 4. The electron image is focused by accelerating and retarding electrodes 7 and 8, and solenoid 9 on to glass target 2 which carries mosaic 3 on the other side. Facing the mosaic and close to it is a mesh grid 10 held at a slightly negative or positive potential to give a datum potential to the mosaic elements. Photo-electrons liberated from the mosaic by the scanning beam are accelerated on to the electrode 11 by means of the electrodes 19 and the electrode 11, which is carried on an optical window 13, forms the first stage of an electron multiplier 21 arranged in the annular space surrounding the re-entrant portion of the tube 15. The photo-emission from the mosaic is arranged to be out of focus when it strikes electrode 11. The annular electrodes may be circular, as shown, or radial. The multiplier 21, Fig. 2, is arranged around the mosaic 3, the electron image space being screened off from the multiplier electrodes by means of screen 26. The secondary emissive electrode is deposited in the flat end wall and is surrounded by the cupshaped electrode 24 which forms the next stage of the multiplier, the solenoid 9 being terminated short of this electrode to enable the electrons to take the correct path 22.

In Fig. 1 the conduit tube 1 has an integrally moulded conically ended snap-in end connector 2-5 for attachment to the fixed bulkhead 52, whilst in Fig. 2 the tube 8 is moulded directly on to a reinforcing layer 10 formed by a helically wound flat metal strip 10 having a plastics self - lubricating (i.e. P.T.F.E. dispersed in a) liner 11 of nylon or Delrim &c., the liner 11 being fixed or having limited axial movement in the reinforcing layer 10, the tube 8 being formed with a screwthread 9 on which a plastics nut 13 is adjustably threadably positioned, the nut 13 as in Fig. 1, having a conical snap-in portion 14, 15 for attachment to the bulkhead 52. Figs. 3 and 4 illustrate alternate arrangements having male and female screw-threaded ends 18, 19 or bonded spigot/socket ends 20, 21 which may be used to interconnect a number of such separate tubes 8 to form a complete conduit and/or form the end fittings for attachment of such conduit to a bulkhead. The conduit may be formed by one tube having any of the end fittings above, which is moulded from polyethylene terephthalate in a mould (22) (Fig. 5, not shown) to form a large cross-section 30, and of shorter length than required (Fig. 6) and then heated and stretched between its ends 32 on a machine (Fig. 8, not shown) or in a hot water bath, whereby the portion intermediate the ends 32 is progressively reduced in cross-section, i.e. necks-in at 33 to a smaller cross-section which prevails over the main part of the tube length, the final stretched length of the conduit tube being several times that of the initial moulded length. After the stretching operation the tube may be subjected to a heat, i.e. thermal stress relaxation treatment. Any mouldable polymeric materials can be used for the tube 1 such as polyesters, polyacetals, polyamides, polyolefins and homo- and co-polymers incorporating substituted or unsubstituted vinyl or vinylidene structural units. The moulded material may comprise a relatively hard polymer having particles of a solid lubricant such as P.T.F.E. dispersed therein.

Title: Improved railway crossing barrier control arrangement
IPC: B61L29/24
Filed: 1957-11-15
Abstract: 867,337. Railway crossing controls. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and VENNING, C. F. D. Nov. 14, 1958 [Nov. 15, 1957], No. 35638/57. Class 105. Railway crossing barrier control arrangement in which the operation of the protective measures-energizing the flashing red lights 13 and lowering the half barriers 14 across the road 12-is delayed after the instant of entry of a train on to either of the insulated track sections 1 or 2 for a period at least greater than the time required for the barriers to move from the closed to the near open positions. The train entry releases one or other of the track relays 1TR or 2TR, the front contacts of which are joined in series with the operating coil of the slow-release relay SR which provides the necessary delay. On releasing, relay SR initiates the operation of the protective measures, when the train clears its track circuit relay SR picks up immediately and the sequence ends with the barriers being raised. The delay prevents the re-operation of t.he protective measures, by another train entering one of the track sections immediately after the exit of the first train, until the barriers have at least almost opened. The track sections 1 and 2 are extended away from the crossing so that the delay does not introduce a belated crossing protection.
