[Also in Division G1] In a system for detecting the formation of ice (see Division G1) reduction of the pulse rate from a Geiger counter 16, Fig. 3, due to ice formation causes the valve 21 to conduct, energizing the relay 22 and opening the contacts 23. This de-energizes relays 30 and 36 which energize the heater 11 for removing the ice and a warning lamp respectively. When the ice is reduced to a preset thickness, 22 is de-energized and 30 and 31 are energized after periods governed by delays 28, 29; 34, 35 respectively. Ice formation then recommences and so long as moderate icing conditions exist the warning lamp 26 will blink. The delay in the lamp circuit is made greater than that in the heater circuit so that under extreme icing conditions relay 22 will be reenergized before 36 is re-energized and the warning lamp will be permanently lit.

Abstract: 1391223 Semiconductor devices SIEMENS AG 11 Oct 1972 [12 Oct 1971] 46806/72 Heading H1K A pair of complementary IGFETS, one of which is a switching transistor and the other is a load transistor are produced by forming the switching transistor in a thin semiconductor layer by the double diffusion technique and simultaneously producing the complementary load transistor during the first diffusion stage. The double diffusion technique utilises two diffusions of opposite types through the same aperture to form the source (or drain) region surrounded by the region within which the channel is induced. The device is produced by growing an N-type layer 2 on a high resistivity substrate, e.g. of spinel, opening windows (26, 27, 28), in an oxide layer (25) and diffusing-in an impurity to form one P-type zone (40) for the switching transistor and two further P-type zones (70, 80) for the source and drain of the load transistor. The load transistor diffusion wndows are covered with an insulating layer, e.g. by oxidizing while the remainder is masked with Si3 N4 which is then etched off, and a further window (226) is opened for the drain of the switching transistor. An impurity is diffused-in to form the N<+> type source and drain contact regions 3, 6 of the switching transistor. The masking layers are removed and parts of the semiconductor layer are removed and replaced by growing insulating material to isolate the two transistors. Conductive connections and insulated gate electrodes are then applied. The switching transistor comprises an N<+> type source region 3, a P-type region 4 within which the channel 41'is induced by the gate 19 and a drain region comprising a lightly doped part 5 of the original N-type layer and an N<+> type contact region 6. The load transistor comprises P-type source and drain regions 7, 8 and an N-type region 9 within which the channel 91 is induced by the gate 21. Two such pairs of transistors may be interconnected together with two selector transistor to form a bi-stable storage element in a memory matrix.

Title: Arrangements for indicating the state of adjustment of optical components in a television camera
IPC: H04N5/232

Abstract: 1,068,210. Television. FERNSEH G.m.b.H. Nov. 4, 1965 [Nov. 4, 1964], No. 46843/65. Heading H4F. The state of adjustment of an optical element of a television camera, e.g. the lens aperture or focal length, is indicated on a picture reproducer, e.g. a view-finder or monitor, which responds to the video signal from the camera by combining with the video signal a signal a characteristic of which varies in accordance with the state of adjustment. The signal may produce a mark at the upper lower, right-hand or left-hand edge of the reproduced picture and may indicate the state of adjustment by its position against a suitable scale. In one arrangement the signal takes the form of a group of four to eight pulses in successive lines at the end of the camera blanking interval whereby a short vertical mark is produced at the upper edge of the picture. The time of the pulses during the lines is controlled in accordance with the adjustment of the optical element by arranging the mechanical adjustment of the element to control the setting of a potentiometer included in the pulse generating circuit. A suitable circuit is described with reference to Fig. 4 (not shown), and a number of suitable pulses which produce different characteristic marks are described with reference to Fig. 3 (not shown). Two marks which indicate two different adjustments may be produced in the first and second halves of a line by controlling the circuit appropriately in alternate fields in accordance with the two adjustments. Alternatively, the two marks may be arranged to appear, one at the upper and one at the lower edge of the picture. Instead of the pulses being confined within the camera blanking interval, they may occur wholly or partially outside the blanking interval, e.g. in the first five lines of the actual picture. The pulses are mixed with the video signal from the camera so that they pass to the viewfinder and monitor but not to the transmission channel. In another arrangement of the invention, Fig. 9 (not shown), the member which adjusts the optical element (the aperture of a zoom lens) is associated with a transparent numbered scale indicating the state of adjustment. An image of the scale is formed on the camera target above the top edge of the image of the scene viewed by the camera and thus appears in a corresponding position in the reproduced pictures in the viewfinder and monitor.
