Title: Improvements in or relating to pick-up tubes of the super-iconoscope type
IPC: H01J31/32
Filed: 1953-11-12
Abstract: 776,763. Television pick-up tubes. RADIOINDUSTRIE. Nov. 12, 1953 [Nov. 19, 1952], No. 31422/53. Class 39(1). In an image iconoscope with high-velocity scanning, means such as electrodes A, B, C, D, are provided between the photo-cathode 2 and the storage target 4 for preventing photo-electrons from reaching some or all of the edge portions of the scanned area ; this provides a black reference signal during each line and/or frame period which may be used to control a variable gain amplifier to to correct for " shading " or " flare effects. As shown in Fig. 2, the scanning beam moves from R to S and the line moves from RS to QT. Thus electrode C provides a black area R R<1> Q<1> Q at the beginning of each line, while electrode A makes a black area Q<11> T<1> TQ<1> of the last few scanning lines. Additional electrodes D, B, D being at a higher level to avoid the scanning beam, may complete a black frame around the whole scanned area, Fig. 3 (not shown). A single frame electrode at the level of electrode D may replace the four separate electrodes. The electrodes may be oblique, obtuse-angled or right-angled, Fig. 4 (not shown), to improve the uniformity of the field at the target. Alternating potentials at line or frame frequency may be applied to the electrodes to effect partial compensation of the flare effect.

Title: Improvements relating to photo-electric cells
IPC: H01L21/08
Filed: 1949-12-09
Abstract: 658,503. Light-sensitive cells. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. Dec. 9, 1949, No. 31686. Convention date, Jan. 17. [Class 40 (iii)] In a photo-electric cell comprising a baseplate supporting a semiconductive layer with a translucent counter-electrode: applied to its outer surface, a barrier layer is created between the semi-conductor and base-plate in order to provide a second rectifying contact acting in opposition to the rectifying contact between the semi-conductor and counter electrode. This second contact allows the useful photoelectric current to pass freely but considerably reduces the leakage currents in the opposite direction. The barrier layer may be constituted by a film, either organic, such as varnish, or mineral, such as quartz, fluorine or cryolite. In the case of a selenium photoelectric cell the base-plate may be constructed of a metal, such as cadmium, zinc, aluminium or antimony, capable of forming with the selenium a non-conducting compound which acts as the barrier layer.

Abstract: 1523829 Rotary regenerator wheel mounting GRANCO EQUIPMENT Inc 4 Aug 1976 32512/76 Heading F4K A rotary regenerator (for heat exchange between hot burnt gases leaving an incinerator and a mixture of fumes and air being fed thereto) has a ceramic wheel 50, Fig. 3b, comprising a central ceramic core 98 and an annular ceramic portion with axially extending gas passages 96. Mounting means for the wheel comprise wedge shaped members 128, 106 which are resiliently biased together to compress the wheel therebetween. The members 128, 106 are at one end of a drive shaft assembly 114, 124 and springs 132, Fig. 3a, which effect the biasing are at the other end. The shaft assembly, which has the reference 52 in Fig. 2, is rotated by a motor 70. The peripheries of both the ceramic wheel 50 and an annular seal block 74 are tapered. The gap therebetween can be adjusted by axial movement of the wheel. A fan 79 blows cooling air through a vertical channel 78 into the shaft assembly, the cooling air flowing as indicated by arrows in Fig. 3b. Some of this air passes through the wheel core and out through conduits 80, 84, Fig. 2. The channel 78 is of bubble alumina and forms a seal with one face of the wheel. From the bottom of the channel 78, air passes through and purges the bottom portion of the wheel as the wheel rotates from the fume and air zone to the exhaust zone. The purge gases then pass into a purge chamber 88 and conduit 90 which leads to the incinerator combustion chamber. The wall of chamber 88 comprises part of a vertical channel 86 of bubble alumina which provides a seal at the hot side of the wheel. As illustrated in Fig. 1 (not shown) a fan (16) blows the fumes and air through the rotary regenerator (26) into an incinerator (12) which includes both a gas-fired grid-type burner (28) and a central vertical air-cooled baffle (32). The fumes may come from a drying oven for lithographed sheets or from a smoke house.

Abstract: 1,255,128. Core sampling. LABORATORIO NACIONAL DE ENGENHARIA CIVIL. 6 July, 1970 [24 July, 1969], No. 32542/70. Heading E1] A method of core sampling comprises inserting a reinforcing member into the rock or soil to be sampled, binding the member to the rock or soil surrounding it and taking a core sample consisting of the member and the rock or soil bound thereto. A hole is drilled from the surface, or from the bottom of a larger diameter hole by means of a drill string having a flange to engage a centring sleeve in the bigger hole. The reinforcing member which may be a steel or plastics bar is inserted into the hole by means of a releaseable coupling head connected to a string of rods. The member pushes cement grout or a plastics binding material already in the hole into the surrounding rock. Alternatively the binding material may be introduced through a bore in the bar after the bar has been inserted. A hole concentric with the bar is then drilled around it and the sample removed.
