Title: Improvements in or relating to Photo-Electronic Imaging Devices
Inventor: GABOR DENNIS
IPC: G03H1/00
Filed: 1966-06-15
Abstract: 1,186,372. Television. COLUMBIA BROADCASTING SYSTEM Inc. 9 June, 1967 [15 June, 1966], No. 26743/66. Heading H4F. [Also in Division H1] An image from a light source modulated by a high frequency is projected on to two photoelectric mosaics deposited respectively on two interdigitated electrodes 2 and 3, Fig. 7, between which a signal of the same high frequency is applied so that the required modulated image is stored, but other images which are not modulated or modulated at a different frequency are not stored. The stored image is recovered by scanning with a light spot (not shown) to derive signals from electrode 3 which are fed to a cathode ray tube 25 scanned synchronously with the light spot. The process may be controlled by a shaft 18 rotating at 25 revolutions per second and carrying discs 20- 26. Disc 20 is transparent over part of its periphery to allow light to pass for the recording process, and the transparent part shades into an opaque part. Disc 21 connects the H.F. source to electrode 3 during the recording stage; disc 22 forms a capacitor which is connected in parallel with electrode 3 during recording and reduced to a small value during read-out, thereby increasing the charge on the screen during read-out; disc 24 connects the electrode 3 to the output during read-out, and a similar switch (not shown) puts a flying spot tube (not shown) into operation. The system can be applied to picking out a weak modulated image from a strong background, for conveying more than one message by a light pattern, or in incoherent holography. Uneven photo-sensitivity may be compensated for by the use of a mask which is applied to the window of the photoelectric device, or to a fibre-optical screen which replaces the window. The mask may be made by inserting a beam-splitting prism between the scanning light spot source and the photo-electric device, the output of which controls the intensity of the light spot; a photographic plate which is to form the mesh is exposed to the beam reflected by the prism (Fig. 12, not shown).

Abstract: 1432798 Nursing bottles A YAMAUCHI 5 June 1973 26837/73 Heading A5X A nipple 3, Fig. 1, for a nursing bottle 1 has a sucking end portion 7, Fig. 2, with a sucking hole 10 which acts as a non-return valve cut in a locally thickened region adjacent the nozzle extremity, a flange 15 formed for engaging the mouth portion 5 of the bottle, and at least one air valve 18, said valve including a stepped cavity, the outer portion of which is wider than the inner portion. The bottle 1 is generally cylindrical in shape and is made of transparent plastics. The mouth 5 is circular and slightly smaller in diameter than the body, and has an external thread 6. The nipple 3 is transparent and pliant, and the end 7 is bulbous. The nipple has a funnel-shaped intermediate portion 8, and a bottle-mouth-co-operating portion 9. In the centre of the nipple end 7 is located the sucking hole 10. Above the hole (11a) or (11b) Fig. 4 (not shown) is a dome-shaped membrane portion (12a) Fig. 4, cross-cut radially with respect to the direction of flow. The flange 15 co-operates with the bottle mouth 5, and a ring 4, inwardly flanged, co-operates with flange 15 so that when the ring is screwed on the bottle the nipple will be tightly sealed to the bottle. The air-valve 18 comprises a cavity 19 and a U-section memibrane portion (20) Fig. 5 (not shown) and is cut radially with respect to the longitudinal axis of hole 19. Both the nipple end and the air-vavle may have X- shaped, Y-shaped or linear cuts in their respective membranes. To protect the membrane (20) an annular rib 21 is formed beneath flange 15 extending beyond membrane (20). When the bottle is not in use, the nipple 3 is removed and reversed, with the nose 7 in the bottle, held in place by the ring 4, and covered by lid (23) Fig. 6 (not shown). For short periods the nipple cover 25 is placed over the nipple to keep it clean. In operation, the hole 10 opens in proportion to the suction applied. As the fluid is sucked out, air is drawn in through the air-valve 18, the amount of air matching the outflow of the fluid. When feeding stops, the hole 10 and the valve 18 close simultaneously.

Title: Dropout detector circuit
IPC: H04N5/94
Filed: 1976-06-30
Abstract: The signal read from a recording carrier, particularly the video signal, is supplied to the input of an amplifier (19). The output of the amplifier is connected via a filter (20), a rectifier arrangement (21) and a low-pass filter (22) to a first input of a threshold device (23) constructed as Schmitt trigger. A second input of the threshold device is also supplied with the signal from the output of the amplifier via a rectifier arrangement (26) acting as amplitude detector and a further low-pass filter (27). When the ratio between the amplitude of the signal supplied to the first input of the threshold device and the amplitude of the signal supplied to the second input of the threshold device has dropped to a particular value, the threshold device generates a switching signal. This indicates that dropout interference is present. <IMAGE>
