Abstract: In order to observe the dry line formed on the surface of wood fibre pulp on the moving wire in a Fourdrinier paper machine, its-atrea of appearance is scanned at a low angle with a thin beam cluster (A 1, B 1 ) which, being generated by a laser radiation source ( 20 ) and representing one or more discrete wavelengths, is distinguishable from the background light. Hereby the surface following the dry line (I) reflects diffusively a major part and specularly a minor part of the arriving radiation than the surface preceding it. A detector ( 30 ) located above the level of the wire observes the intensity of the diffusely reflected radiation (A 3, B 3 ) hitting it and delivers continuously, as the beam cluster scans the pulp surface, a signal which is proportional to said intensity. The signal is digitized repeatedly and processed in real time in a computer, whereby a series of signals in the direction of the paper machine produces one dry line point and, if repeated for different positions in the cross direction, the dry line consisting of such points. The dry line and the values of quantities and deviations characterizing it are displayed by graphical and numerical terminals and actuators of the paper machine are controlled according to it automatically, synchronously with the scanning of the dry line region. The method can be implemented also in such paper machine environments, to which the earlier methods for structural reasons do not apply.

Abstract: 806,505. Transistors. GENERAL ELECTRIC CO. Aug. 25, 1955 [Aug. 30, 1954], No. 24476/55. Class 37. A junction transistor comprises a semi-conductor wafer having a collector electrode over the whole of one face, a second electrode on the opposite face comprising a plurality of contacts connected together and a third electrode covering the remainder of the opposite face, either the second or the third electrode being of the alloyed junction type so as to form emitter and base electrodes. The Figures show a transistor having a fernico or nickel collector electrode plate 3 attached to an N-type germanium or silicon wafer 2 by an acceptor containing solder which provides a PN junction 10. The base electrode comprises a fernico or nickel plate 5 having apertures 8, and held in good ohmic contact with wafer 2 by a donor containing solder. The emitter consists of a plurality of alloy junction electrodes provided in apertures 8 by fusing dots 7 of acceptor material to the surface of the wafer. The PN junction under each dot is restricted so that it lies entirely within the aperture 8, and may be formed by placing a small quantity of indium in a recess 11 in wafer 2, and heating to provide the P-type region. The emitter and base electrode constructions may be reversed, by providing a PN junction under plate 5, and arranging for dots 7 to have ohmic contacts to wafer 2. The form of the collector electrode facilitates cooling by conduction, and the close spacing between the emitter, collector and base electrodes allows operation at high power. Specification 727,900 is referred to.

IPC: G08G1/08
Abstract: 1,084,272. Road traffic signals. AMALGAMATED WIRELESS (AUSTRALASIA) Ltd. Jan. 18, 1965 [Jan. 16, 1964], No. 2103/65. Heading G4Q. A timing circuit for a traffic control system comprises a capacitor C1 having a long discharge time and adapted to control the discharge rate of a second capacitor C2 which is reset each time a vehicle passes over a detector. Initially, contacts 12 and 13 are closed and then opened, thereby leaving C1 charged to a potential determined by the setting of RV1 which is connected through the contacts to the positive supply terminal 11 and directly to the negative supply terminal 15. The charge on C1 cuts off V1 and is gradually reduced by the connection to RV2. Each time a vehicle approaches the road on which traffic is stopped, it operates a relay which operates a contact 20 which transfers a charge from C3 to C1 in a sense to make the grid of V1 more positive. A positive charge may be added to Cl from RV3 when contacts 17 and 18 are closed by means (not shown) operated when the gap between vehicles in the green phase exceeds a predetermined level. As the charge on C1 is reduced by the above means, V1 gradually conducts and increases the rate of discharge of C2 through RV5 and RV6. C2 is the main timing capacitor and is re-charged each time vehicle-operated contacts 21 and 22 are closed. When C2 is sufficiently discharged, V2 conducts and operates relay T which changes the traffic lights. RV1 controls the delay before V1 conducts, i.e. the period during which extensions of green time provided by operation of contacts 21 and 22 remain constant. RV5 controls the amount of the reduction of later extensions when V1 conducts, and RV6 controls the normal extensions. Different potentiometers may be provided for each phase so that each phase may be treated differently.
