Title: Improvements in or relating to cross-bar switches
Inventor: DROZD ZDZISLAW
IPC: H01H67/26
Filed: 1960-09-16
Abstract: 916,864. Automatic exchange switches. ZAKLADY WYTWORCZE URZADZEN TELEFONICZNYCH IM KOMUNY PARYSKIEJ. Sept. 16, 1960, No. 31923/60. Class 40 (4). Selecting fingers in a cross-bar switch each comprise a pair of arms 2 spring tensioned towards each other so as to pinch a select bar 1 between their ends. The tension avoids vibration and consequent malfunction of the selecting finger. As illustrated, the select bar 1 moves to the left or right as viewed in Fig. 2 to place one or other of the selecting finger arms under a hook 5 at the end of spring pile operating posts 4, seen best in Fig. 3. Actuation of an armature 8 then deflects the finger, as shown in Fig. 1, to actuate the selected post 4 and make contact with the wires 11. In its deflected position the armature 8 masks the hooks 5 of unselected operating posts 4 and bars the entry of any further selecting finger. When the select bar restores the finger arm is retained by friction between the post 4 and armature 8. The selecting fingers are anchored by a pivot stud 3 or may be rigidly mounted on the switch frame.

Filed: 1934-11-09
Abstract: 425,883. Copying telegraphy. STANDARD TELEPHONES & CABLES, Ltd., Crown House, Aldwych, London.-(Assignees of Materiel Telephonique Soc. Anon. ; 46, Quai de Boulogne, Boulogne-sur-Seine, France) Nov. 9, 1934, No. 32377. Convention date, Jan. 6. [Class 40 (iii)] In a facsimile telegraph system in which a plurality of parallel lines are simultaneously scanned and transmitted, the receiver operates on the start-stop principle. Before each letter is scanned, a start signal is transmitted and at the receiver is applied to one or other of the magnets r1 ... r5, Fig. 1, to flex a flange 21 to close a contact, (not shown), to start the tape traversing mechanism and energise a relay 15. The relay 15 attracts its armature 19 to allow the stop 16 to move beneath the notches 22 in the printing bars 1 ... 5. Thereafter the signals corresponding to the scanning lines are applied simultaneously to the corresponding magnets r1 ... r5 to actuate the printing-bars. The relay 15 is a slow release relay and only releases after one or a group of letters have been transmitted. In an alternative embodiment, the printing magnets r1, Fig. 3, are shunted by a low resistance winding of a relay d, so that the start signal energizes the relay d to close a contact a which energizes a relay Ed which clutches the tape traversing mechanism and two cams K, K1 to a continuously rotating shaft. A locking circuit for relay d is also closed over contact 3, its right hand winding and contact a. Cam K rotates to open contact 2, removing the shunt from the printing magnets r1 and to close contact 1, maintaining a circuit for relay Ed. Cam K1 rotates to open contact 3, and release relay d. At the conclusion of the reception of one letter, cam K opens contact 1 to de-energize relay Ed. To ensure a clear impression on the tape, the magnets r1 .. r5 instead of actuating printing bars may cause the interposition of a stop b, Fig. 4, between the tape and an anvil g, a continuously vibrating hammer f making the marking impression. The hammer f preferably commences vibration on the reception of a start signal. Alternatively, the magnets r<1> may displace a cam to bring its raised portion under the hammer f.

Abstract: 282,064. Naamlooze Vennootschap International Octrooibureau, (Assignees of Meyer, F., Joachim, H., and Germer, E.). Dec. 10, 1926, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus. - A luminous discharge device filled with metal vapour alone or mixed with one or more gases is provided with an incandescent electrode and has a wall a part or the whole of which is transparent to ultra-violet rays and, if desired. also to visible rays. Both electrodes may be incandescent so as to act alternately as anode and cathode and permit full-wave operation. The Specification as open to inspection under Sect. 91 (3) (a) also comprised the following. To enable luminous discharge tubes to be operated at ordinary supply-main voltages, they are provided with an incandescent metal, alkaline-earth oxide, or similar highly active cathode. To facilitate starting, an auxiliary anode may be arranged close to the cathode so that the discharge between these eliminates the space charge around the cathode and reduces the starting voltage with respect to the main anode. In this arrangement the cathode may be cold initially, the auxiliary discharge heating it to start its emission. When the main discharge is started it may automatically interrupt the auxiliary discharge. The discharge may also be started by a high-voltage induction current impulse. Luminescent substances may be placed in or around the tubes, or the tubes may be of such substances. Designs may be arranged on the tubes, e.g. by cutting or etching opalescent glass tubes, or applying luminescent paint on tubes transparent to ultra-violet rays. The luminous tube may be combined with an incandescent lamp, which may constitute its cathode, to imitate daylight. In long tubes having a number of pairs of electrodes, balancing resistances are provided to equalize illumination. Gaspressure maintaining substances may be employed in connection with the tubes. This subject-matter does not appear in the Specification as accepted.
