Abstract: 1,078,068. Photo-electric monitoring devices. J. WEIR, S.J.S. VERMAAK AND I. LADANYI. Oct.14, 1964, No. 41960/64. Heading G1A. To monitor the movement of lifts, skips and rail vehicles to give a warning of excessive speed apparatus is provided including normally closed and normally open switch contacts. Provision is made to open the normally closed contacts whilst a body is passing the test position and to close the normally open contacts at the commencement of the time the body passes the test position for a predetermined period. A warning is given if both sets of contacts are closed at the same time. The figure shows a light source 2 whose radiation normally falls on photo-transistor 1 but may be interrupted by a passing body. Interruption of the light causes release of relay A and energization of relay B which is held energized until the charge in capacitor 3 has leaked away. If relay A is re-energized before relay B releases a circuit is completed through contacts A 1  and B 1  to give a warning or operate a brake. The power supply for the apparatus may be stabilized by means including transistors 11 and 12 and lamps 9 and 10 are included to indicate the condition of the two relays.

Abstract: 1,085,830. Photo-electric controlled lamp adaptor. GLOBAL PATENTS Ltd. Oct. 5, 1965 [Jan. 14, 1965], No. 42218/85. Heading H2E. [Also in Division G1] A plug-and-socket lamp adaptor is associated with a photocell-controlled encapsulated reed switch for switching a lamp in response to changes in ambient light; arrangements are described in which the switch and photo-cell are both housed in the adaptor body, in which the switch is in the body but the photo-cell at some remote sensing position and in which both are at the remote position. In Fig. 2 a plug 12 and socket 16 of the screw type. are shown, the current path between studs 22 and 42 being broken by the switch 28 and that between the threads 24 and 40 being unbroken and provided by the internal structure. A photo-cell is shown both inside at 54 and outside at 54A, although in practice only one would be present. The photo-cell, of the variable resistance type, on increasing the current in coil 30, due to an increase in ambient light, opens the reeds against bias magnet 32. If the reeds are the normally closed type then the bias magnet is unnecessary. In another arrangement (Fig. 6, not shown) the cell energizes a heating coil of a thermal magnet. Light reaches the inside photo-cell 54 by entering at the edges of a clear plastics disc 42 and internal reflection on the face of a conical cut-out 44. A band 56 containing a window may surround the disc edge to select the direction of ambient light. The bottom of disc 42 and the top except for a circular area 54 are painted to obstruct the light. In front of the cell is an opaque filter 82 or 64, to select the general level of intensity. A filter whose density changes with light intensity and one which passes ambient daylight to the exclusion of artificial light may also be used (Fig. 8, not shown). A neon lamp in parallel with the reed switch lights when the switch is open to show that the main lamp is sound.
