Title: Optical-electronic semiconductor devices
IPC: H04B10/00
Filed: 1970-09-24
Abstract: 1309938 Electroluminescence SIEMENS AG 24 Sept 1970 [26 Sept 1969] 45427/70 Heading C4S [Also in Division H1] An opto-electronic semi-conductor device comprises a common housing 1 (e.g. of darkened insulating material) containing a crystal electrically stimulated to emit light and a semiconductor photo-sensitive detector electrically isolated from the crystal but optically coupled thereto by a rod-shaped light conductor 10 of elastomeric material which is compressible and expandable and which returns to its normal shape on removal of a load. The crystal 6, rod 10 and photo-detector 7 may be coaxially arranged, the rod of transparent silicone rubber, e.g. compressible by 10-20% of its length without exceeding a resiliency of 1 g., the housing rotationally symmetrical, and the device may include end-plates 2, 3 serving as electrodes mounted on glass or ceramic housing 1, with further electrodes 8, 9 in glass insulators and possibly third electrodes. End-plates 2, 3 are sealed to housing 1 by a binder, preferably vacuum tight, crystal 6 may be a luminescent diode, such as a laser diode, for example, while detector 7 may be a photo-diode or phototransistor. Rod 10 may be glued to crystal 6 and detector 7, e.g. at the point of radiation incidence such as at a PN junction, silicon rubber adhesive being specified. The length of guide 10 is determined by the voltage to be withstood. Assembly procedure is described, and the rod 10 should be compressed in the assembly to ensure adequate contact, e.g. may be a few mms. longer than the available spacing. Lengths of a few mms. and a few cms. are exemplified. Advantageously, plates 2, 3 have a different construction, facilitating identification during assembly and use. Use as a relay is instanced, the housing being lightproof to reduce the effect on the environment. Prior art disclosures includes optical links of glass, crystal or glass fibres.

Title: Improvements in or relating to a measuring or regulating device
IPC: G03B7/085
Filed: 1961-12-20
Abstract: 941,856. Photo-electric exposure control for photographic cameras; automatic control of light intensity. EUGEN BAUER G.m.b.H. Dec. 20, 1961 [Dec. 22, 1960], No. 45626/61. Headings G2A and G3R. The amount of light passing through a camera lens is detected by a photo-resistor the output of which controls an apertured diaphragm associated with the lens whereby the light intensity for exposing the film is maintained constant at some predetermined value. As shown, a cinecamera comprises an objective lens 2, a film gate 3 behind which is moved a film 4, a rotatable shutter 5 having a conical mirrored surface 7 and a photo-resistor 30 which receives light reflected from surface 7 and which is electrically in circuit with a device 20 operating a movable diaphragm 17 associated with the lens 2. The device 20 comprises a rotatable frame 19 which is connected to the diaphragm 17 and which has two parallel legs carrying superposed coils 22, 23 arranged in a magnetic field system 24, 25 so that both coils are affected by the same field strength whatever the angular position of frame 19. The coil 23 is connected together with photoresistor 30 in one branch 32 of a circuit supplied by a battery 33 which may also drive the camera motor; a second branch 31 in parallel with the first, contains the coil 22 together with resistors 44, 38 to 43 which are adjustable to suit the various operating conditions, e.g. film sensitivity, filter factors &c. When these conditions have been set and the amount of light passing through lens 2 is correct, then the currents in branches 31 and 32 are equal and device 20 is in an equilibrium position. Should there be an increase in the amount of light incident on the photo-resistor 30, and hence incident upon the film 4 when the shutter 5 frees the gate 3, then the resistance of 30 decreases, the current in branch 32 increases and the force acting on coil 23 becomes the stronger so that the frame 19 rotates about spindle 21 until the diaphragm 17 limits the amount of incident light to the original setting, the currents in branches 31 and 32 being then again equal. The opposite action takes place when the amount of light passing through lens 2 decreases. The frame 19 may carry a pointer which indicates the light strength on a scale. In a modification Figs. 5 and 6 (not shown), the diaphragm has separate apertures for the lens 2 and the photo-resistor 30.

Title: Seal Assembly
IPC: F16J15/32
Filed: 1966-10-13
Abstract: 1,162,146. Seals. B. F. GOODRICH CO. 13 Oct., 1966 [14 Oct., 1965], No. 45863/66. Addition to 979,792. Heading F2B. A seal assembly includes a sealing ring 10 comprising a body 23 and an integral diaphragm 24 with a tubular extension 27a terminating in a sealing edge 28 which is urged into contact with a rod 16 to be sealed by deflection of the diaphragm about its juncture 25 with the body 23, the amount of deflection being limited by an adjusting sleeve 12 engaged with the ring 10. The diaphragm is clamped at a thickened portion 27 between a ridge 30 in the rod casing 18 and an end 33 of the sleeve 12 which is threaded in the body 23. The ring 10 is sealed to the casing 18 by a metallic packing ring 42 compressed between the body 23 and spacers 40 by a loading nut 14 which is threaded in the casing and bears against the body 23. The diameter of the sealing edge 28, in its free state, may be made either greater or less than the rod diameter. When it is greater, the seal is assembled by mounting the ring 10, with the sleeve 12 partially screwed therein, on the rod, tightening the nut 14 until the diaphragm 24 abuts the ridge 30 and further tightening the nut 14 to deflect the diaphragm and urge the edge 28 against the rod until the desired sealing load is obtained; the sleeve 12 then being tightened to abut the diaphragm. When the free sealing edge diameter is less than the rod diameter, the sleeve 12 is first screwed in the ring 10 until the edge 28 is expanded sufficiently to allow the ring to be slid over the rod. The nut 14 is tightened to hold the diaphragm against the ridge 30 and the sleeve is then screwed back to allow the edge 28 to contract into sealing contact with the rod 16 until the desired sealing load is obtained.
