Abstract: 1,131,187. Gunn effect amplifiers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 3 Nov., 1966 [15 Dec., 1965], No. 49419/66. Heading H3T. [Also in Division H1] In a Gunn effect amplifier arrangement the Gunn effect element is provided with at least one additional control electrode which is intermediate its end electrodes and is adapted to receive control potential. The additional electrode may extend over the major part of the length of the element in a direction approximately parallel to the drift velocity of the charge carriers in the element, and may be insulated from the element or in ohmic contact therewith. The control potential affects the effective D.C. bias on the element and thereby regulates the negative resistance exhibited by the element. In this way the degree of amplification and the frequency at which maximum gain occurs can be controlled.

Abstract: 1,241,799. Laminating-apparatus. MARPLE PRINTING CO. Ltd. 2 July, 1968 [2 Nov., 1967], No. 49760/67. Heading B5N. [Also in Divisions B2 and D1] In a process for laminating fabrics, adhesive is applied to a fabric web A by an applicator 16 having a roller 36 in such a manner that, as the fabric is moved away from the roller, tendrils of adhesive a are formed which stretch and then break and contract on to the fabric. For this purpose, the roller 36 is helically grooved and is rotated in a trough 35 of adhesive, of which it forms an end surface, the adhesive carried by the roller being controlled preferably by a bar 37 and a resilient doctor blade 38 having a smaller clearance in the middle than at the ends. A non- flammable urethane adhesive is suitable. The fabric web A is fed to the adhesive applicator 16 over a blanket 14 and slat expander rolls 12, 13 and 15, and after the application of the adhesive, it passes around a drum 17, to permit removal of excess solvent and preliminary drying, and then beneath a pressure roller 23 by which a second fabric B, fed over a blanket 22, is laminated to it. The composite web C is then passed round a heated drum 27, against which it is held by a blanket 28, to complete evaporation of solvents. This drum operates up to about 95 C., curing of the adhesive being completed subsequently at lower temperatures. A fabric web may be applied to each side of the fabric web A to produce a three-ply composite.

Title: Method of compensating spurious signals which occur in the scanning of originals
IPC: H04N5/217
Filed: 1971-10-27
Abstract: 1340727 Television FERNSEH GmbH 27  Oct 1971 [29 Oct 1970] 49986/71 Heading H4F In the quantitative evaluation of picture signals derived by a television camera, to compensate for spurious signals which are superposed upon the actual picture signals as a result of defective lighting and scanning, compensating signals are obtained by scanning a standard original in a standardizing operation, these signals being stored and used to control a compensating amplifier during subsequent scannings. In the embodiment described lines scanned during the standardizing operation are divided into individual line sections, e.g. 32, and the signals associated with each line section are integrated in an analogue storage unit over a plurality of lines, e.g. 12. The values obtained by integration are then converted into digital compensating signals (4-bit words) and the differences between these signals and the maximum value of these signals (obtained from a previous scanning of the standard original) are stored in a circulating memory which is stepped forward in synchronism with the scanning of the line sections i.e., at the end of the 12th line of each picture section (13 lines) the compensating signals related thereto are recorded in the circulating memory in one line period i.e. during the 13th line of the picture section. A tap-off point is provided on the circulating memory for the compensating signals which are passed to a further circulating memory since each "line" of compensating signals must be employed during a complete picture section of 13 lines. In the standardizing operation the output of the camera is preferably fed via a threshold circuit to the analogue storage unit.

Abstract: 1,168,841. "No break" supply systems. INDUSTRIELLE ELEKTRONIK AGIE LOSONE BEI LOCARNO A.G. 14 Nov., 1966 [27 Sept., 1966], No. 51011/66. Heading H2H. [Also in Division G3] In a multi-phase system producing power from a D.C. supply through inverters, for each phase two waves are generated which are variably phase displaced by equal and opposite amounts to a reference phase angle. For each phase, a pair of inverters are employed connected to a common oscillator 1 and each comprising a monostable multivibrator 2, a Schmitt trigger circuit 3, a flipflop circuit 4 and firing circuits, e.g. 7, 8, the latter triggering controllable rectifiers in a unit, e.g. 5 supplying energy to a transformer winding 143 connected serially with another winding 144, the output being taken from terminals 150, 151. The load voltage is detected and compared with a reference in a differential amplifier 14 the output of which angularly displaces in the multivibrators 2 the oscillator output by equal and opposite amounts so that the phase angles of the voltages relative to one another are maintained equal, hence voltage variation with asymmetric loading is also compensated. The system may be substituted for the arrangement disclosed in Specification 1,095,029 for providing a "no break" supply system. A common oscillator may feed all the pairs of inverters (Fig. 3, not shown) and be tied to a main supply (20) through a frequency multiplier (28), which oscillator is free running should the main supply dissappear. The load 15 is normally started from the mains and subsequently changed to the inverters through a switch 16. The arrangement may supply a variable speed motor by arranging for the reference to have a variable frequency.

[Also in Division E1] The upper chamber 24, Fig. 1A, of a vertical hydraulic ram cylinder having a piston 10 suitable for forcing a drill (not shown) against the bottom of a bore hole is connected by an axial duct 25 to a supply pump 62, Fig. 1C, whilst the lower chamber 26 is connected by an annular duct 22 and by circumferentially spaced tubes 34, Fig. 1B, to a sump 37a under pressure, the tubes 34 being connected through a restricted passage 49 to an annular oilfilled expansion reservoir 35 having a flexible wall 39 bearing against said tubes 34, and duct 22 being connected to chamber 26 through a passage 16 controlled by a normally open spring-biased valve 18 but which on a sudden increase in pressure in chamber 26, e.g. caused by sudden downward movement of piston 10, is movable to another position in which duct 22 is isolated from chamber 26 and connected to chamber 24 thus preventing cavitation in the latter and undue pressure rise in expansion chamber 35. In operation, drilling mud is pumped into a central passage 27 formed of the upper and lower hollow piston rods 11, 12 and by a lower casing 31 screwed thereto and drives a contra-rotating turbine (not shown) which transmits drive through a speed reduction gear-box 55 to the drill and to an oil pump 62 located in a sump 37a. The pump delivers through a flow control unit 21 at a rate responsive to variations in turbine speed, excess oil being returned to sump through a dump line 67. The pressurized drilling mud gains access to the flexible wall 39 through posts 45 in tubes 41 and so tends to contract the reservoir 35 and force oil through the restriction 49 into conduit 22 and passage 21 to replace oil leaking from chamber 26. The return, i.e. upward, stroke of the piston 10 is effected when the turbine and hence the pump is inoperative by the ram cylinder 13 being allowed to descend under gravity whereupon oil in chamber 24 is discharged through passage 23, duct 25, control unit 63 and dump tube 67 to the sump 37a and oil is supplied from the sump to chamber 26 through conduit 22 and open valve 18.
