Filed: 1924-10-28
Abstract: 226,782. Western Electric Co., Ltd., (Assignees of Smythe, E. H.). Dec. 24, 1923, [Convention date]. Automatic exchange systems.-The terminals of a connector are divided into groups of unequal size, serving, for example, different Private Branch Exchanges and the wipers are stepped to the wanted group under control of a counting chain built up by the final digit. With this arrangement, all subscribers can be numbered consecutively, and no alteration in numbering is necessary when the size of a P.B.X. group is altered. When the subscriber A reaches the connector shown, relays 3, 4, pull up, and relay 5 repeats the final digit to the counting relays 7, 9, 17 - - 20, &c., which lock up in succession, two for each impulse, and ground terminals in the path of wiper 8 of the connector. Relay 10 pulls up over wiper 8 and energizes the self-interrupting stepping-magnet 12. When wiper 8 leaves the terminal, relay 10 falls back, but re-energizes to cause a further step when the next terminal is encountered. When an ungrounded terminal is reached, relay 10 fails to re-energize, and relay 11 which was energized in parallel with the stepping magnet falls back sluggishly and energizes relays 6, 22. Relay 6 locks up, disconnects the left hand winding of relay 22, and releases the counting relays. Relay 22 connects relay 10 to the test wiper 15 over its own right-hand winding so that the switch hunts for an idle line, the test terminal of which being ungrounded, relay 10 fails to re-energize and the sluggish relapse of relay 22 energizes relay 32 in series with the cut-off relay (e.g. 31). Relay 32 energizes ringing relay 35. The reply of the called party causes relay 33 to remove a short-circuit from switching-relay 34 which locks up and shortcircuits ringing relay 35. Release. Relay 29 which is energized on the relapse of relays 3, 4, energizes the stepping magnet over off-normal springs 16. the change over of which completes the release. Busy tone. If all the lines are busy, wiper 15 moves on to a terminal such as 38 to energize relay 39 which connects up busy transformer 40. Relay 32 is unable to energize in series with relay 39.

Title: Improvements in aircraft lighting systems
IPC: B64D47/06
Filed: 1945-10-03
Abstract: 601,079. Aircraft lighting systems. KING, J. T. Oct. 3, 1945, No. 25715. [Class 4] [Also in Group XL (a)] In an aircraft lighting system in which parallel light beams are projected forwardly from the leading edges of the tail plane, the positions of the beams are adjustable about a transverse axis by remotely controlled means and also by a gyroscope. As shown, the fixed landing lights 3 are located in the leading edges of the wings 2 and project downwardly convergent beams LB. Two lamps 15, ultraviolet light tubes 16 and reflectors 14 are carried by arms 13 mounted on the output shafts 12 of two motors 8 and are positioned so as to project parallel beams AB through windows 7 in the leading edges of the tail plane 6. The motors are actuated by a synchronous transmission system comprising a transmitter 10, amplifier unit 9 and receivers coupled to the motors. According to the setting of the transmitter 10, which is adjustable by the pilot, the means may be maintained horizontal, or at a desired angle to the horizontal, by a gyroscope 11 coupled to the transmitter and provided with manual or automatic devices for rendering it inoperative. The ultra-violet beams are arranged to impinge on graduated tubes 33 containing fluorescent material and arranged on either side of the pilot's cockpit. With the transmitter set to maintain the beams horizontal, the pilot is thus given an indication of the movement of the aircraft in the pitching plane. A further visual indication is given by the beams emitted by the lamps 15. If the gyroscope is rendered inoperative and the beams AB are set to intersect the beams LB (see Fig. 6, not shown), the pilot is given an indication of altitude when approaching a landing place. Other uses of the invention are described. The circuit of the lamp 15 and tube 16 includes slip rings and brushes 17, 18 and 19, a switch 21 which may be operated to select ultra-violet or incandescent light beams, and a mercury switch 23 and motor-driven rotary switches 20, 20a which operate to cause flashing of the ultra-violet light beam on the high side when the aircraft banks. A similar arrangement may be provided to cause flashing of the incandescent light beam. Fluorescent markers may be provided on a landing deck for co-operation with the ultra-violet light beams. Specification 584,391 is referred to.

Filed: 1964-06-23
Abstract: Apparatus for donning and doffing a flyerframe comprises an assembly which can be moved towards and away from the frame in a direction transverse to the axes of rotation of the flyers and adapted to remove the full bobbins and replace them with empty ones; the assembly has means to grip the bobbins at both ends and for releasing the bobbins from their rotational positions in the flyers.  The assembly is mounted in a carriage which runs on rails along the frame, means being provided to stop the carriage at fixed places. The assembly is moved to and from the frame on guide bars and can be moved vertically on guide-bars by a rack 27 Fig. 5, (not shown), when a meshing pinion 39 is rotated towards a carrier 49 to which the doffed bobbins are transferred and which carries a supply of empty bobbins.  The assembly deals with four spindles at a time, and for each spindle has upper and lower grippers in the form of tongs opened and shut when a cam is rotated.  For each spindle, also, it has a bar 22 which can be advanced to separate the bobbins from their associated spindles.  At the end of a set, the flyers stop in a position which does not hinder the transverse withdrawal of the bobbins.  The assembly is advanced, so that the tongs can grip the bobbins.  To separate the bobbins from their flyers, the bars 22 are advanced so that their inclined ends 42 engage and lift the members which couple the bobbins to their flyers: to separate the bobbins from their spindles, cams act on the bobbin-grippers to lift the bobbins. The assembly is now retracted to bring the bobbins beneath the carrier 49 and are raised by rotating pinion 39 so that the bobbins are forced on to holders in hangers similar to those used in the creel of the associated spinning frame.  The grippers are released and the assembly retracted slightly to await movement of the carrier to bring empty bobbins in line with the grippers. (The empty bobbins are arranged alternately with holders for the filled bobbins).  The assembly advances, the grippers grip the empty bobbins; the assembly rises slightly to detach the bobbins and descends to its original position whereafter the assembly advances to don the empty bobbins.  The movement of the assembly is produced by hydraulic or mechanical means under the control limit switches or programming means.
