Abstract: 1364175 X-ray tubes MAOHLETT LABORATORIES 15 March 1972 [2 July 1971] 12157/72 Heading H1D An X-ray tube of the type wherein a rotating anode carried by a shaft 46, Fig. 2, is supported on bearings 32 from a fixed support 24 sealed to the envelope, is provided with a leaf spring contact device electrically interconnecting members 46 and 24 independently of the main bearings so that the latter need not necessarily be conductive. In Fig. 2 the contact device comprises a contact button 62 fixed to one end of a leaf spring 60 secured to a ring 58 which is fixed to the support 24. The button 62 should be a self-lubricating metal such as silver, silvercopper, or silver-tungsten-molybdenum, and the co-operating surface or insert 64 should be a hard metal such as rhenium, tungsten or rhodium. The spring pressure also serves to take up any slack in the bearings, and a cylinder 66 surrounding the contact device prevents particles produced by wear from migrating towards the bearings. A similar arrangement may be provided when the anode shaft is outside instead of inside the fixed support (Fig. 3, not shown).

Title: A new or improved apparatus for the protection and testing of electrical earth connections
IPC: H02H11/00
Filed: 1955-04-29
Abstract: 800,605. Protective cut-out systems. NICHOLSON, C. H., and DUKE, G. E. April 30 1956 [April 29, 1955; Sept. 15, 1955], Nos. 12385/55 and 26395/55. Class 38 (5). In a system for disconnecting a portable apparatus 10 in the event of failure of the earth circuit or leakage to the frame, starting is initiated by operation of push-button switch S2 which completes the circuit comprising the secondary of transformer T, normally-closed push-button S1, lamp P2, contacts a1, a2, closing relay coil B,. main neutral connector N, the neutral to earth connector at the supply source, main earth connector 17, relay coil A, connector 25, casing 10, and connector 26 to the transformer secondary. This ensures that relay B will only operate, to complete the supply to the apparatus, if the Neutral-to-Earth connection is complete at source and the casing 10 is fully earthed. When relay B closes, contacts b7, b8 are closed to remove the connection to the supply source and maintain the safety circuit. In the event of failure of an earth connection the safety circuit will be broken and relay B will be de-energized to interrupt the supply. In the event of leakage to frame the excess current will pass through relay coil A which operates at a current slightly in excess of that normally flowing in the safety circuit. Operation of relay A opens contacts a1 a2 to de-energize relay B, and closes contacts a3, a4 to seal itself in. Lamp P2 may be of the fuse type.

Abstract: 646,239. Linear-dimension gauges. BRYANT CHUCKING GRINDER CO. May 7, 1948, No. 12663. Convention date, June 14, 1947. [Class 106 (ii)] A portable linear - dimension gauge of the pneumatic type comprises a handle portion 1 through which passes an air line 44 from an air gauge 48, a body extension 2 and a reduced diameter portion 4 small enough to enter between the surfaces to be gauged, and slotted throughout its length as shown in Figs. 2 and 5. A movable feeler member 7 is pivoted at 8 and is disposed between the arms of the slotted member 4, side play being prevented by cheeks 6 provided on the opposite arms, as shown in Fig. 2. A pin 9 connecting the two arms passes through the member 7 and limits the movements of the member 7 to within the required limits by means of a large clearance hole. A reed member 12 shown in Fig. 3 is secured to the member 7 by means of a reed 11 and screws 14 and 17 tapped into the body of the members 7 and 12 respectively, the flexibility of the reed permitting limited movement of the member 12 with respect to the member 7. A pair of co-operating faces 35, 36 are provided on the members 7 and 12 to control the escape of air from the passage 37 provided in the member 7. Gauging feeler points 26 and 30 are mounted on members 7 and 12 to contact the gauging points of the workpiece. A pair of guide contact points 31 mounted on either arm of the member 4 are arranged to steady the gauge and assist in placing the gauging feeler points 25, 30 across the diameter of a tube as shown in Fig. 5, or at right angles to a pair of flat surfaces as shown in Fig. 7. When the feeler points 25, 30 have contacted the surfaces to be gauged the gap between the surfaces 35, 36 determine the flow of air through the conduit 46 shown in Fig. 8. Air supplied from a conduit 53 via a filter 54 and pressure regulator 52 enters the gauge tube 48 and the rate of flow past the surfaces 35, 36 is indicated by the position of the bob 50 in the tube 48 in known manner.

[Classes 39 (i) and 40 (v)] In electron discharge apparatus in which the tube includes a byepass electrode in the electron path, a resistance or impedance is arranged in series with the supply voltage thereto and the voltage of the byepass electrode in the absence of space current is greater than that of the next succeeding accelerating or collecting electrode but of the same order of voltage when space current flows. In this way a large slope may be obtained without excessive current at the anodes. The impedance in series with the byepass electrode may be frequency selective so as to extract a selected frequency. Fig. 4 shows a radio receiver using an electron multiplier as the intermediate frequency amplifier which is provided with byepass electrodes 31 associated with tuned circuits 41 to increase the selectivity. Auxiliary electrodes 47 may be provided in front of the secondary cathodes 26 as described in Specifications 516,621 and 531,541 and the byepass electrodes may be immediately in front of the secondary electrodes or in front of the auxiliary electrodes. A photoelectric cathode may be used for relay operation and modulated light may be used so that the apparatus is rendered frequency selective by the provision of tuned impedances in the circuits of the byepass electrodes.
