IPC: H04N5/374
Filed: 1968-03-07
Abstract: 1,258,572. Television. PLESSEY CO. Ltd. 3 March, 1969 [7 March, 1968], No. 11274/68. Heading H4F. [Also in Divisions G1 and H1] A sampling arrangement for providing access to individual photo-diodes (such as D, Fig. 1) of an array of photo-diodes, each of which is initially charged and is discharged to an extent dependent upon the amount of light impinging it, comprises conductor means (such as line conductor 1 and column conductor 2) associated with each photo diode and capacitively (C L  and C C ) coupled thereto so that a potential change in the conductor means produces an output signal which is dependent upon the charge state of the photo-diode. Each photo-diode is normally reverse biased, and when the potentials on conductors 1 and 2 are simultaneously reduced to zero for a particular photo-diode, the reverse bias potential thereof is reduced to zero when the photo-diode is unexposed, but when exposed to light the photo-diode is effectively forward biased and the excess charge is conducted into the substrate of the photo-diode in the form of a current pulse I. The current pulse I which is dependent upon the amount of light falling on the photo-diode, is amplified A and forms part of the output video signal V 0 . The same sampling technique may be used for a one dimensional array of photo-diodes having only a single column conductor. The sampling arrangement constructed in integrated form is shown in Figs. 3 and 4, and comprises a transparent semi-conductor substrate 3 having a diode junction 4 formed between it and a diffused region 5. Contact is made to each diffused region 5 through holes in an insulating layer 6 by means of a squareshaped metal contact layer 7. A second insulating layer 8 is deposited over the layer 7 and two further areas 9 and 10 of metal are deposited thereover to overlie the metal contact 7 to form the coupling capacitors C C  and C L  respectively. At the same time column conductors 11 are deposited as extensions of the areas 9 such that the capacitance C C  is formed between the column conductor 11 and the diode contact 7. A third insulating layer 12 is deposited over the metallic areas 9, 10 and 11 with a hole 13 therein located over the area 10, and a further metallic layer 14 is deposited to form the line conductor. Insulating layers 6, 8 and 12 may comprise silica or silicon nitride, metallic areas 7, 9, 10, 11 and 14 may comprise aluminium and the photo-diodes may be formed from silicon, germanium, indium arsenide or indium antimonide.

Abstract: 1350519 Flushing sanitary closets MICROPHOR INC 14 June 1972 27877/72 Heading E1C A flushing system for a sanitary closet, particularly for use in a mobile installation or where there is a need to conserve water, comprises a bowl portion 14, a hollow base portion 16 in communication with the bowl via a slide valve 20, a solenoid valve 66 arranged to admit a predetermined amount of water to flush the bowl when the slide valve is open, and a relay valve 100 to admit compressed-air to the interior of the base portion 16 after the slide valve has re-closed to transfer the water and waste to a holding tank 28, the compressed-air being admitted for a predetermined time which is adjustable by altering the setting of a bleed valve 104 which controls the length of time the relay valve 100 remains operative after actuation. To effect these operations in the desired sequence, a manually-operated lever 22, which may be positioned on the toilet in either of the two positions shown, is mechanically linked to the slide valve, as indicated at 40, and is also coupled to a pull rod 50 having cam surfaces 56 58. The former of these cooperates with a follower 62 on an actuating arm of a switch 64 connected in series with the solenoid valve 66, whereby water is admitted to the bowl during downward movement of the handle of the lever 22 for a period determined by the time taken to fully depress and release the handle. The cam surface 58, on the other hand, merely pushes aside a spring-loaded pivoted plate carrying a follower 82, during downward movement of the handle, but on return movement of the lever 22 it. cooperates with the follower 82 to raise and lower a lever 80, which acts on the plunger 86 of a valve 88 to cause a puff of air from a compressed-air reservoir 92 into a control reservoir 102, charging the latter to a pressure sufficient to actuate the control piston of relay valve 100. The pressure in the control reservoir 102 subsequently reduces at a rate determined by the setting of the bleed valve 104, which thus determines the operating time of the relay valve and hence the duration of the supply of compressed air via the relay valve 100 to the chamber formed by the interior of base 16, which is now airtight since slide valve 20 was re-closed on return of the lever 22.

The moulding material may be a metal with or without fibre reinforcement, such as tungsten or boron fibres, or may be a thermoplastic resin with or without fibre reinforcement such as carbon or glass fibres, or a thermosetting resin with a fibrous reinforcement. A billet 19 of deformable material is located centrally of a compression die arrangement comprised by two annular elements 14, a split core 16 and elements 18; half of the elements 18 are shaped to form radial portions of the article whilst the other half provide thinner webs interconnecting adjacent radial portions. Initially, when the elements 14 are moved towards each other all the elements 18 are moved together to cause billet material to flow into the radial parts of the cavity and a portion to flow into the peripheral part 23; in this stage those elements 18 which shape the intermediate portions are moved to their final shaping positions. In the second stage the elements 14 and the remaining elements 18 are brought to their final positions, Fig. 3, causing material to flow radially and then peripherally around the part 23. A modified apparatus, Fig. 8, for producing a wheel with spaces between adjacent spokes comprises a die element 29 with sector shaped abutments 33 providing radial spaces therebetween and a central cavity 34; die elements 38, 40 combine with element 29 to provide the wheel rim. A material billet placed in the cavity 34 is displaced radially by an element 35 after the tops of the radial spaces have been closed by elements 37. After this initial stage the elements 37 and 38 are moved to their final positions.
