Title: Improvements relating to photo-conductive targets and especially television pick-up tubes and analogous image pick-up tubes
Inventor: LUBSZYNSKI HANS GERHARD
IPC: H01J29/45
Filed: 1953-08-11
Abstract: 794,331. Semi-conductor devices. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 11, 1954 [Aug. 11, 1953], No. 22096/53. Class 37. [Also in Group XL (a)] Time-lag in a low-velocity photo-conductive iconoscope is reduced by increasing the thickness of the target layer above 8 microns and so reducing the capacity. This is done by combining the photo-conductive layer with a further thicker layer of semi-conductive material having a range, for the charge carrier involved in the photo-conduction, which is long compared with that of the photo-conductive layer, so as not to impede conduction. In one form the photo-conductive layer 5 of P-type material (such as Se or Se+Te) is deposited directly on the conductive signal plate 4, and the layer 6 of P-type semi-conductor covers the layer 5 and is exposed to the scanning beam. The layer 6 may be a single crystal, or of mosaic form to reduce transverse conduction; it may be cassitarite (SnO 2 ), Brookite (TiO 2 ), polybasite (9Ag 2 S, Sb 2 S 3 ) or spodumene (LiAl(SiO 4 ) 2 ). In another form, an N-type photo-conductive layer of antimony trisulphide is deposited on one side of an N- type semi-conductive layer of Rochelle salt or alkali halide, and a signal plate on the other side. To improve colour response the second layer may also be photo-conductive, for example, to blue light while passing on the red light to the red-sensitive first layer; in this case the second layer may be cadmium sulphide. The relative thicknesses may be 0.5 microns for the photo-conductor and 19.5 microns for the semi-conductor. Specification 794,332 is referred to. Reference has been directed by the Comptroller to Specification 705,533.
Patent GB-368649-A (GB)
Title: Process for the treatment of welded structural members, of light metal, with closed, hollow cross section
IPC: B23K5/12
Filed: 1931-08-04
Abstract: 368,649. Preventing corrosion. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Aug. 4, 1931, No. 22101. Convention date, Oct. 4, 1930. [Class 123 (i).] Corrosion of the inner surfaces of the welds of hollow structural members, particularly of magnesium alloys is pre vented by flushing out with water the welded tube a through a hole bored at f and reheating the tube while passing dry air through to dry it, or alternatively, drying with hot air. The hole f is welded up and the tube then contains dry air. Under these conditions any remaining traces of the welding agent do not set up corrosion. The outside of the welds is freed from welding agent by washing. Increased security against corrosion may be obtained by introducing through the hole f a small quantity of marine glue, tar, or viscous lacquer, which covers the joints. In the case of complex structural members, these may be completely filled with the sealing agent and then emptied and the hole welded up.

Title: Improvements in centrifugal separators
IPC: B04B1/08
Filed: 1936-08-13
Abstract: 476,823. Centrifugal separators. BERGEDORFER EISENWERK AKT.-GES. ASTRA-WERKE. Aug. 13, 1936, No. 22305. Convention date, Sept. 6, 1935. [Class 23] A centrifugal machine for separating liquid mixtures in which the ratio between the components may vary, has one or more of its bowl outlets connected to a discharge pipe by tightening devices, such as stuffing boxes or paring devices. The component in the discharge pipe is discharged through a spring controlled valve to keep the boundary surface between the components in the bowl in a substantially constant position. In the machine shown in Fig. 2, the light component, to avoid foaming, is passed from the bowl over the weir 17 to the chamber 15 from which it is removed by the paring device 14 and passed to the discharge pipe 16. This pipe has a spring-loaded valve, or is located on a suitable level to prevent the level 19 of the liquid from approaching the edge of the paring disc. The modified form of machine shown in Fig. 3, is used to discharge the heavy component from the bowl neck 22 through the tight joint 23 and outlet pipe 24, without contact with the air. The light component discharges from the channel 25 against the counter pressure of a spring-loaded valve 26. Both components therefore discharge against uniform pressure which is independent of the quantity of liquid passing. Uniform pressure in the outlet 27, Fig. 5, is obtained by means of a piston 30 supporting a weight 29 and arranged at the top of the outlet. The liquid passes to the pipe 28, and the pressure on it is independent of the quantity flowing. The same result can be achieved by discharging against a constant head of liquid.

Abstract: 1,125,687. Electric control systems. GENERAL DYNAMICS CORP. May 18, 1967 [May 20, 1966], No. 23142/67. Heading G1N. [Also in Divisions B3 and G4] In the production of a longitudinally tapered strip in a rolling mill, the spacing between the rollers 11, 12, Fig. 1 is continually adjusted during a run by movement of wedge 18 into the gap between a backing roller 13 and a fixed wedge 19, under the control of a hydraulic ram 17. For larger adjustments of the spacing between runs a conventional screw-down arrangement 21 is provided. The ram 17 is controlled by an error signal from an amplifier 36 indicative of the difference between the actual position of the wedge 18, obtained from potentiometer 37, and the required position to produce the required spacing of rolls 11, 12. The required position of the wedge is obtained by multiplying a signal indicative of the required taper (change in thickness per unit length), from computer 22 (see Division G4), with a signal indicative of the instantaneous position of the rolls 11, 12 along the strip, obtained from a pulse tachometer 25, counter 24 and digital-to-analogue converter 23, in which the multiplication also occurs. To compensate for, e. g. changes in the roll diameters, the output from the computer 22 is fed to an adjustable potentiometer 31. To compensate for non-linearity between the position of the wedge and spacing of the rolls 11, 12, the computer 22 may be modified to take into account deflecting forces acting on the frame 10 which produce the non-linearity. In operation, when the strip has left the rollers, a force detector 38 senses the resulting reduction in force and transmits a signal to energize relay 33 connecting a clock 41 to the counter 24 which causes the wedge to be driven to the end of its stroke in preparation for the next run.
