Title: Improvements in automatic telephone exchange systems providing ancilliary services
Inventor: JOHNSON BENJAMIN BERTIE
IPC: H04Q3/00
Filed: 1954-11-03
Abstract: 793,948. Automatic exchange systems. TELEPHONE MANUFACTURING CO., Ltd. Jan. 19, 1956 [Nov. 3, 1954], No. 31838/54. Class 40 (4). Special services are available to subscribers in a P.A.X. on the dialling of an appropriate digit or digits into a register which is thereafter unresponsive to further digits, the register connects the calling line to the special service requested and is then dismissed without disturbance of the connection. The invention is described with reference to Fig. 1 which is schematic. Calls to other subscribers. In a 50- line system a calling line is connected over a line-finder such as PR1 to a feed bridge FB1 having access to a register marker RM. The register marker registers a first digit of 1-5 and a second digit 1-9 or 0. Each connector such as CON1 comprises five electro-mechanical bridges with five banks of contacts,. each bank giving access to two lines, discrimination between a pair of lines being effected by a switching relay. The register marker uses the second digit first to energize a finger magnet and, if necessary the switching relay in the appropriate connector CON1 and then uses the first digit to energize the appropriate bridge magnet to complete the connection. Connection to facility services. Facilities such as staff-call, paging, tie-line working, and party-line revertive calling are provided if the subscriber dials a single digit 6-9 or 0. The register marker RM recognizes the digit as being greater than 5 and closes a contact sp1 (Fig. 2, not shown) so that it does not wait for a second digit. The impulses exceeding 5 are then registered to energize the appropriate one of five bridge magnets in the connector already sized and mark one of five conductors BX5. The bridge magnet, say that corresponding to level 5, in CONI extends the marked conductor in the group BX5 to energize the finger magnet 5/1 in the case of facility 5. The marked conductor in the group BX5 is also extended over further contacts of the operated bridge magnet to energize operating magnet FC5 in the facility selecting bridge SEM5 to complete a 3-wire circuit to the desired facility. A relay A (not shown) pulls up to energize TBA1, so disconnecting the calling line from the feed-bridge FB 1 and releasing the register-marker RM and marking circuits. The operate bridge magnet FC5 selfholds until relay A (not shown) is restored at the end of the call. If the number of connecting circuits is greater than five the additional connecting circuits gain access to the facility circuits over an upper level in the bridges SEMISEM5, a switching relay discriminating between the upper and lower levels (Fig. 3, not shown).

As shown a rod 11 of corundum is mounted in a chuck 18 so that it may be rotated and an oxy-gas flame 39 from a burner 29 is applied, the flame starting from a point on the rod remote from its sharp tapered end 13 and being moved towards the apex by means of a lever 37 which movement is stopped just before the apex which fuses and forms a rounded point, Fig. 8, not shown. The intensity of the flame may be adjusted during its travel towards the apex by means of an arm 55 attached to a valve 81 and operating in a slot 57, or the burner may be of the multiflame type as shown in Fig. 3. Various shapes of ends may be formed on the rods, e.g. bulbous and of less diameter than the rod, Figs. 4 and 10, not shown, hemispherical, Fig. 12, not shown, or bulbous and of greater diameter than the rod, Fig. 13, not shown. The rod may also be given a smooth heat glossed surface. The Specification as open to inspection under Sect. 91 comprises also a rod having a heat glossed surface without the rounding of the end.

Title: Improvements in or relating to the manufacture of cathode ray tubes
IPC: H01J29/28
Filed: 1952-12-30
Abstract: 724,167. Cathode ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 30, 1952 [Jan. 2, 1952], No. 32982/52. Class 39 (1). A method of manufacturing a cathode ray tube comprising a fluorescent screen which on the cathode side is coated with a metal layer which extends onto the lateral wall of the tube, a temporary intermediate layer being used which, after application of the metal layer is removed by heating, is characterized in that, after the formation of the fluorescent screen and before the application of the temporary intermediate layer, a layer of labyrinth structure is applied to the lateral wall of the tube, which layer prevents the intermediate layer from adhering directly to the lateral wall and prevents peeling of the metal layer from the lateral wall of the tube. The labyrinth structure layer may be formed by the spraying of powder, adherence to the lateral wall of the tube being obtained by binder left from settling of the fluorescent screen or by binder, e.g. potassium silicate solution, applied to the lateral wall of the tube. The powder may be previously mixed with a binder or the particles of the powder may be previously coated with a binder. The powder may be "Alundum" (Registered Trade Mark), sand or zinc sulphide, or may be the same material as used for the fluorescent screen but less con glomerated. The metal layers on the fluorescent screen and on the lateral wall of the tube may be produced simultaneously by evaporating a supply of metal. The intermediate layer can be applied to the fluorescent screen by decanting a solution of the intermediate layer material for example a solution of nitrocellulose in butyl acetate, the solution floating on a filling liquid, for example water.

Title: Improvements in and relating to electrical control systems
Inventor: PEARCE HOWARD RAYMOND
IPC: G05D3/14
Filed: 1952-12-30
Abstract: 736,233. Controllers; control of D.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 18, 1953 [Dec. 30, 1952], No. 33025/52. Class 38 (3). Relates to electrical control systems for industrial plant employing a motor-operated regulator for determining the value of an operating quantity of the plant. As shown, the armature of a motor M driving a rolling mill is connected in a Ward-Leonard circuit with a generator G having its field winding GF connected in series with rheostat FR which is controlled by a pilot motor PM. A field winding PMF of the pilot motor is de-energized when the moving contacts of potentiometers P1, P2 occupy similar positions. Movement of an operator's control member to change the voltage derived from potentiometer P2 energizes the field winding PMF, and the pilot motor rotates to adjust the field rheostat FR in such a direction as to bring the moving contact of the potentiometer P1 again into a similar position to that of the potentiometer P2, the potentiometer P1 being mechanically coupled to move in unison with the field rheostat FR. The field winding PMF is shunted by oppositely-connected rectifiers R or other non-linear resistors so that, when the voltage applied to the field winding is small, only a small proportion of current is diverted from the winding PMF. For larger values of said voltage the impedance of the rectifiers falls, thus limiting the maximum energization of the pilot motor. In a modification, the field winding of the pilot motor has constant energization and the armature of the motor is connected to potentiometers P1, P2. In another arrangement, Fig. 2 (not shown), the pilot motor has two oppositely-wound field windings connected in series with respective rheostats. One rheostat is coupled to a control member and the other to the field rheostat FR, the oppositelywound windings counter-balancing one another when the rheostats occupy similar positions. When the rheostats are not in corresponding positions, however, the pilot motor is driven to adjust the speed of the main motor in the required sense. The pilot motor may be used for brush-shifting, adjusting the position of an induction regulator, or driving other control apparatus. The operator's control member may regulate switches by means of which the current or voltage derived from the potentiometer P2 is adjusted in accordance with the position of the member.

In one modification, the base end flaps 8 have no wings 9 and gussets 10 are the same shape as gussets 11, while the side 3 has an extension flap to co-operate with an adhesively treated top side. In another modification, the top is formed in two parts, connected to sides 3 and 4.
