Title: Improvements in indicators
IPC: G08B25/00
Filed: 1932-01-27
Abstract: 387,502. Electric signalling systems. CORY CORPORATION, C., 754, Lexington Avenue, Brooklyn, New York, U.S.A. Jan. 27, 1932, No. 2468. Convention date, Feb. 7, 1931. [Class 40 (i).] The ratio of movement of the rudder and the pointer of a rudder indicator is altered after the rudder has moved through a predetermined angle from its zero position. The rudder is connected to the shaft 1 and the pointer is controlled by the shaft 11 either directly or, as described in the Specification, by means of an electrical signalling system of the resultant field type. The indicator dial is shown in Fig. 3. Mounted on the shaft 1 by means of the bushing 6 is a sector 5 the teeth 8 of which mesh with the teeth of gear wheel 9 during movement of the shaft 1 through a predetermined angle. The wheel 9 is fixed to the shaft 11 and controls the movement of the indicator pointer 2. As the shaft 11 moves it carries the crank 15 with it and the link 13 moves so that when the sector 5 moves out of engagement with the wheel 9, the pin 16 is firmly seated in the end of the slot in the link 13 and is held there by the tension of spring 21. Further movement of the shaft 1 is thus communicated to the shaft 11 by means of the spring 21 co-operating with pins 16, 14 and link 13 and the ratio of movement between the pointer and rudder shaft is reduced.

Title: Improvements in and relating to indicator circuits
IPC: H04H60/04
Filed: 1950-02-03
Abstract: 733,141. Monitoring arrangements. BRITISH BROADCASTING CORPORATION and TAYLOR, J. C. Feb. 2, 1951 [Feb. 3, 1950], No. 2905/50. Class 40 (4). In a communication system, such as the land-line system used to feed radio programmes from the studios to, the transmitters, in which engineers exercise control in respect of the volume of the signals passing through the system and/or in respect of giving cueing signals to the signal sources, such an engineer endeavouring to exercise control in respect of one source may find that it is already being controlled from another control position. The invention provides an indicator circuit by which he can ascertain the identity of the other control position which is controlling the source. The drawing shows two control positions A and B respectively. Each control position includes a multi-bank selector S of which the bank shown is wired to lines L1, L2, L3 used for indication purposes in respect of programme sources Nos. 1, 2, 3 respectively. Other banks (not shown) serve to connect the selected programme source through the control position to a radio transmitter and may also connect a manual volume control equipment into this circuit. Further banks (not shown) connect the control position to telephone lines to the respective sources over which the engineer may give cueing signals to operators at the sources. If the source selected at one control position is already under control from another position the relevant telephone line will test busy, and it is also arranged that no control may be exercised from the said one position. Each position has a first switch consisting of a pair of contacts T which is closed whenever a source is selected by selector S, and a second switch consisting of contacts H which is normally in the condition shown but which changes over when the selector S selects a source which is not under control from any other position. It will be assumed that source No. 1 is under control from position A and that the engineer at position B then selects the same source. Switches T A , T B  and H A  are operated but H B  remains normal. The engineer at position B then closes his paging switch MB, whereupon relay PSB pulls up, followed by PKB and the relays PK at all other positions are disconnected. Relay PLA operates over L1, and grounds the busbars associated with lamps X, C and 4, so that with PAB and PBB up, lamps X, C and 4 at position B are lighted, thus indicating the identity of the position from which the source selected is being controlled. If during the time that switch MB is closed another engineer closes his switch M to make a check, he is given an indication that checking is in progress. This indication is given by the lighting of lamp Z at his position (not shown) over front PS and back PK contacts in series.
