Patent NL-299583-A (NL)
IPC: H04Q3/62
Abstract: 1,021,817. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 22, 1962], No. 41240/63. Heading H4K. An electronic system acting on the selfseeking principle as described in Specification 953,895 provides for PBX hunting by the use of a control circuit for each group which is taken into use when the line called by the directory number is busy to effect the selection of an idle line from the other lines of the group. Line circuit, Fig. 2. This is somewhat similar to that described in Specification 1,021,816. In the normal condition, transistor 206 is switched on, while transistors 207, 208 are switched off. When a call is initiated, the change of potential on wire 230 switches on 207 which in turn switches on 208. The potential at P3 is clamped to that on wire 43 which is removed when an idle link is allotted. It then becomes that of the collector of 207 and a firing pulse controlled by capacitor 218b is passed to point X to effect switching. The switches are held by way of resistors 217, 216, 224 and 208 is switched off. If no switching path is established, 208 remains on and a further attempt is made during the next allotting interval. Assuming that a path is established, dialling switches 207 off and on to change the potential at P3. When the line is called, a ground marking on T, U switches 206 off, and in consequence 208 is maintained off but 207 is switched on. The potential at P3 is now such that a firing pulse controlled by capacitor 218a is applied at X to effect switching. 206 switches on again when the marking is removed and switches off 207, but this is switched on by the reply of the called subscriber, and its off condition gives a release signal when the subscriber goes onhook. If the line is busy, the switching off of 206 produces no change sufficient to generate a firing pulse since 207 is already on. Group controller, Fig. 3, for sequential hunting. Terminals A of the line circuits other than the first are connected to transistors such as T39. When the first line L31 is called and is found to be busy transistor T5 operates and a ring counter steps under the control of an oscillator T31, T32. In consequence, transistors such as T39 which are normally operative are switched off in turn to control transistors 206 of the corresponding line circuits, the action continuing until an idle line is found. Group controller, Fig. 4, for random hunting.- Terminals B of the line circuits are connected over individual resistors to transistor T42 and terminals A to transistor T41. When a particular line is called a negative-going pulse fires T42, and, after a delay produced by a capacitor 428, T41 switches off, whereupon if the called line circuit has not already done so, the remaining line circuits race to fire through the switching network. Other embodiments are described, Figs. 5, 6, 7 (not shown), in one of which the hunting is partly sequential and partly random.

Title: Refractory tube production - for high pressure sodium halide lamp envelopes modified zone melting of pre formed sintered tube
IPC: B23K26/12
Filed: 1975-12-04
Abstract: In the mfr. of a refractory tube starting from a preformed tube of refractory material round which a concentrated heating zone is arranged by means of radiant energy of uniform intensity in such a way that a molten ring of uniform height is formed in, and is displaced along, the tube, the height being such that the surface tension forces and gravitational force hold the molten ring connected to the solid parts of the tube on each side thereof while the relative translatory motion between the refractory tube and the heating zone is regulated so as to displace the molten ring along the tube, (a) the radiant energy is formed by laser energy and the heating zone is formed by a series of laser beams of semicircular form uniformly distributed round the tube and each beam is focussed on the refractory tube to form the molten ring therein, and (b) the focussing is carried out in such a way that the energy density distribution of each beam is adjusted to give equal absorption of the laser energy round the whole surface of the tube within the molten ring. Enables the virtually full theoretical density to be achieved by eliminating any porosity introduced by e.g. impurities. Also permits, when appropriate, the production of a tube as a single crystal, so that limitations arising from the presence of grain boundaries, e.g. chain of atmosphere during treatment, are no longer of importance. The technique is particularly suitable for the production of Al2O3 envelopes for sodium halide-especially NaI- lamps, which operate at high pressure and temperature.
