Abstract: 1331617 Flash photography CANON K K 10 Dec 1970 [10 Dec 1969 14 Jan 1970 18 Feb 1970(2) 20 Feb 1970] 58611/70 Heading G2A The combination of an electronic flash unit and a camera has an indicator circuit which indicates an inoperative condition when either the flash circuit Fc is not able to illuminate the flash discharge tube LF, e. g. insufficient voltage across the discharge capacitor 4, and/or the photographic settings on the camera are not appropriate for flash photography, e.g. incorrect setting of the diaphragm, shutter speed and distance, and also indicates an operative condition when both of these conditions are met. An oscillator circuit OF has its output connected via capacitor 35 to an ammeter 36 whose pointer thus oscillates to indicate an inoperative condition. The oscillator stops oscillating only when a transistor 30 is rendered conductive and this results only if a switch SW 2  is closed as the result of the setting of the camera appropriate for flash photography and if the voltage on discharge capacitor 4 is sufficient to cause lamp 2 to glow so that the base voltage of transistor 30 permits conduction therethrough. In a modification of this embodiment, Fig. 2 (not shown), the switch SW 2  is replaced by a changeover switch, and the transistor 30 is powered from its own independent current supply (40). In a further embodiment, Figs.3 and 4 (not shown), the photometric measuring circuit formed by 9' and 36 is replaced by an indicator lamp (45) in the collector circuit of a transistor (44), the lamp flashing to indicate the inoperative condition and emitting steady light to indicate the operative condition. A time-constant circuit may be provided to control the time of triggering of a flash by-pass tube under the control of detected light, Figs. 5, 7-10 (not shown).

Title: A communication switching system
Inventor: CURTIS ROBERT BARTLETT
IPC: H04Q3/545
Filed: 1968-12-23
Abstract: 1,253,530. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 23 Dec., 1968 [27 Dec., 1967], No. 60961/68. Heading H4K. In a multistage switching network, paths between inlets and outlets thereof are held by intermediately located junctors irrespective of the conditions of the inlets and outlets. Such a system of holding is useful where it is desirable to have a plurality of paths in respect of a same call in existence simultaneously so that for example digit receiving and digit sending can be effected concurrently while at the same time a direct path between the relevant incoming and outgoing junctions is prepared for immediate cut-through when digit signalling ceases. Particular description.-Seizure of an incoming trunk 105-99 from another office is noted by a ferrod scanner 117 whereupon stored programme type processor 115 allots a suitable digit receiver 110-0 and instructs a marker 114 to set up a path thereto from the trunk. The incoming and outgoing link portions of the switching network each comprise a 100 x 100 cross-bar switch. The marker operates the appropriate select magnets on the processor's instructions and then, after it has seized a suitable free junctor, it operates the hold magnets. The processor, apprized of these operations, then transmits a signal to the junctor in order to operate a pair of relays therein, one relay being effective to ground the sleeve wire and thus hold the connection solely under control of the junctor and the other relay serving to cut-through the speech wires. With Path 1 now fully set-up the causes the process or incoming trunk circuit to revert a proceed-to-send signal to the originating exchange. As soon as sufficient digits have been received in the processor it instructs the marker to set-up a path (Path 2) to a suitable outgoing junctor 110-99. The procedure is the same as indicated above except that the speech-wires are not cut-through as yet in the junctor. Thereafter the processor causes the marker to set-up an outpulser/outgoing trunk connection (Path 3) so that sending may commence as soon as the distant office reverts a proceed-to-send signal. When digit receiving and sending is complete, the processor signals junctors 104-0 and 104-49 to release their path holding relays so that Paths 1 and 3 are released, and signals junctor 104-99 to cutthrough the speech wires of Path 2 whereby the tandem connection is completed.
