Title: Improvements in or relating to centrally controlled telecommunications exchange systems
IPC: H04Q3/54
Filed: 1970-09-28
Abstract: 1293057 Party line systems SIEMENS AG 28 Sept 1970 [29 Sept 1969] 46008/70 Heading H4K A centrally controlled telecommunications exchange including party line subscribers has provision in which when a party line subscriber from whom calls are barred attempts to initiate a call that party is connected to a device which monitors the line to detect the end of this call attempt and independently monitors the line to detect calls initiated by the other subscriber of that line. As shown when a subscriber Tn1 or Tn2 goes off hook the corresponding winding RI or RII of a relay R in the common line circuit Z responds. The common line circuit is connected over a switching network K to a connection set (for receiving dial signals), the calling subscriber is identified and a storage location is interrogated to determine whether calls from or to this subscriber are barred and whether his substation is busy or idle. If a call is barred or if after the wanted subscriber designation has been sent the connection cannot be completed the line circuit is connected to a tone monitoring device D. If the call is from subscriber Tn2 the central control enables a relay B. Via contacts 1c, 1b and 2c, 2b and windings I of relays A and E the line wires are connected to negative and earth respectively to supply line current of one or other polarity (depending on which subscriber is calling) to the calling subscriber during tone transmission. This battery supply operates a relay U1 or U2 in a selection circuit G connecting the calling substation to both line wires and isolating the other subscriber. If the call is from a barred subscriber a relay H is operated by the central control changing over the position of contacts 1h and 2h connecting both line wires to negative battery via high resistance windings of relays A and E. The high resistive battery supply is unable to energize relay U1 or U2 and accordingly both subscribers remain connected to one line wire. Relay A monitors the calling subscriber to detect the return of his handset to the " on hook " condition to enable the circuit D to be released while the relay E monitors the other subscriber to detect a call initiation request. Energization of relay A or E closes a corresponding contact a or e in a circuit including a persistence check device V which repeats signals to the central control. Thus one subscriber can be barred without inconvenience to the other.

Abstract: 1,094,866. Casting processes. E.Q. SYLVESTER. Nov. 1, 1965 [Nov. 23, 1964], No. 46078/65. Heading B3F. In a method of casting using moulds having a bottom pouring opening means are provided to purge the mould cavity prior to casting by the introduction of inert gas into the mould through the pouring opening, to purge the mould at a predetermined rate to avoid turbulence and mixing with the air being displaced. A destructible member 80 of paper, aluminium foil or other similar material is located by a spring clip 82 in the underside of the mould ingate assembly 12. A gasket 86 of asbestos cemented to the member abuts the ingate and an annular passage 78 is defined around the pouring opening of the mould. Inert gas introduced under pressure through zones 59, and 64 into the annular passage 78 acts against the gasket and member 80 flexing it downwards and so admitting the gas radially into the passage 32 and into the mould cavity. Casting material subsequently poured into the mould destroys the member 80 and so fills the mould cavity.

Abstract: 1,088,772. Mechanical interrupters. W. HOLZER. Nov. 13, 1964 [Nov. 15, 1963], No. 46374/64. Heading H2B. In order that a switch for making regular intermittent contact may be very compact and yet operate contacts with a high degree of accuracy relative to the time interval between operations, the principle of coincidence of recesses on the peripheries of two discs revolving at different speeds in a predetermined relationship is applied to an internal epicyclic gear. A disc 6<SP>1</SP> is driven by a shaft 15 which also drives an eccentric 10 causing a wheel 7 to move around the inside of a fixed internal gear 6 by teeth 8 thereon engaging recesses 9 in wheel 7. The peripheries of disc 6<SP>1</SP> and wheel 7 are arranged such that recesses 11 on wheel 7 can register with a recess 13 on disc 6<SP>1</SP> to allow a follower 4 to operate contacts 5 only when such register occurs. The wheels may be moulded in plastic without loss of accuracy in switching. The drive between wheels 6 and 7 may be by friction instead of gear teeth.

Abstract: 1,197,230. Electrode materials and processing. GENERAL ELECTRIC, and ENGLISH ELECTRIC COMPANIES Ltd. 23 Sept., 1968 [12 Oct., 1967], No.46591/67. Heading H1D. An electric discharge lamp, in particular a high pressure sodium-mercury vapour lamp, including an envelope of light-transmissive refractory oxide material of high alumina content and containing a filling which consists only of sodium, mercury and a rare gas, has a pair of tungsten electrodes, between which the discharge passes, which are activated by a quantity of an alloy of thorium and sodium disposed near the inner end of the electrodes and the electrodes being free from oxygen-containing substances capable of liberating oxygen during operation of the lamp. Each electrode may comprise a tungsten rod overwound with a double coil of tungsten wire at the inner end with a sliver of thorium foil wrapped round the inner coil and held in place by the outer tungsten coil. The thorium sliver may be melted on to the inner coil. The electrodes are mounted in the lamp and the envelope is evacuated, filled and then sealed. The lamp is then subjected to a preliminary operation to vaporize the sodium of the filling which on subsequent cooling combines with the thorium in the electrodes to form the thorium-sodium alloy activator. In an example, the filling comprises 10 mg. of sodium, 30 mg. mercury and xenon at 20 mm. Hg. pressure at room temperature, and the electrodes are supported by niobium end discs which are sealed to the sintered polycrystalline alumina envelope by a Ti-Va-Zr alloy.

Abstract: <PICT:1073630/C1/1> In the production of evacuated vessels comprising an evacuated bulb formed wholly or partly of glass, e.g. a television cathode ray tube, a protective band of metal is mounted on the bulb and adapted substantially to fit and surround a predetermined glass zone of the bulb by causing the glass zone and the inner face of the band to bear against one another while the glass zone is in a plastic condition, and then subjecting the bulb to an annealing operation. The cone 11 of metal or glass of a cathode ray tube is held in the jaws of a fixed chuck 12 whilst the viewing plate 13 is held by suction-effect on a movable sleeve 14, both parts being adapted for synchronized rotation.  A metal band 20, e.g. of aluminized steel, is supported by lugs 20a on a crossbar 21 in turn attached to a sleeve 22 and a plunger 23 forming the piston of a cylinder 24.  Burners 32-34 are appropriately mounted to heat the edges of the cone 11 and plate 13 and also the band 20. The plate 13 and band 20 are then moved so that the plate 13 is welded to the cone 11.  The plunger 23 is then operated to push the band around the tube and position it over the glass weld.  The burners 32-34 are turned off and air is introduced through a tube 29 into the sealed tube to blow out the glass around the seals into contact with the band 20. The band 20 preferably has a peripheral groove running round it into which the soft glass can be blown.  Entrapped air escapes through passages in the metal band.  The tube is then annealed.
