Title: Improvements in or relating to fluid metering apparatus
IPC: G01N15/12
Filed: 1957-09-03
Abstract: 865,069. Electric tests. COULTER, W. H., and COULTER, J. R. Sept. 3, 1957, No. 27795/57. Class 37. In a system for counting the number of particles in a liquid a measured quantity is drawn through a small hole in a container, each particle interrupting an electric circuit, the interruptions being counted. In the arrangement shown, the liquid 58 is drawn through a small aperture 47 into a further container 41. As each particle passes through the aperture it interrupts the conductive path between electrodes 50, 54. The liquid is drawn in by the mercury siphon arrangement comprising reservoir 26 and capillary tubes 20, 21, 28. Initially cock 13 is open and the mercury is drawn up into the reservoir by suction applied at tube 12. The cock is then closed and the mercury tends to equalize the level in the two branches 20, 21 drawing further liquid 58 through aperture 47. When the mercury reaches contact 32 in a branch 28 of the capillary tube it sets the counter mechanism 39 which is then able to count each passage of a particle through aperture 47. Counting continues until the mercury reaches contact 31 when the counter is switched off. The volume of the capillary bore between contacts 31 and 32 represent the measured quantity of the sample liquid drawn into tube 47. The configuration of the branch (shown in plan in Fig. 2) ensures that the suction head remains substantially constant throughout the measuring operation. Specification 865,069 is referred to.

Title: A method of manufacturing thyristors
Inventor: MOULT ROGER HARVEY
IPC: H01L29/74
Filed: 1967-06-16
Abstract: 1,212,995. Semi-conductor devices. JOSEPH LUCAS (INDUSTRIES) Ltd. 27 May, 1968 [16 June, 1967], No. 27893/67. Heading H1K. Only the anode-base junction 13 of a Si thyristor extends to the periphery of the die containing the device, so that when a number of such devices formed in a large semi-conductor wafer are to be separated by scribing, only the anode-base junction 13 is affected, and the device characteristics are therefore unimpaired. In the embodiment shown, a P-type anode region 12 and several P-type gate regions 14 are formed by boron diffusion into an N-type Si wafer 11. The anode region 12 extends completely across the lower wafer surface, while each gate region 14 occupies a restricted area of the upper surface, defined by oxide masking. An N-type cathode region 16 is formed by oxide masked phosphorus diffusion into each gate region 14. Electrodes are then applied, the cathode electrode 19 providing a short-circuit over part of the periphery of the cathode-gate junction 17. The wafer is then divided into separate dice by scribing only through the anode-base junction 13. In a second embodiment a single gate region (14), Fig. 2 (not shown), is diffused across the entire upper surface of the wafer, which is then etched down to below the level of the gate-base junction (15) to form a plurality of mesas, each of which will define a single thyristor. The drive-in stage of the gate diffusion process may be carried out in two parts, respectively before and after etching to form the mesas. The devices are then completed as described above, and are separated by scribing between the mesas so that again only the anode-base junction (13) is affected. The various diffusion stages may be replaced by epitoxy.

Abstract: 835,900. Fuel briquettes. BRIKO N.V. Sept. 12, 1956 [Sept. 13, 1955], No. 27927/56. Class 50. In a process for making fuel briquettes, coals other than lignite are treated with a small amount of a low molecular weight aliphatic monocarboxylic acid, e.g. acetic or formic acid, and the treated product, either alone or in admixture with a further solid fuel in finely divided form, is briquetted at a temperature of at least 45 ‹ C. The coal to be treated may be in finely divided form, e.g. having a particle size from 0.1-0.2 mm., and the treatment may be carried out at a temperature between 80‹ and 100‹ C. A small amount of paraffin wax or liquid paraffin may be added to the treated coal. Lignite may be added to the coal before treatment with the acid, or lignite treated with a low molecular weight aliphatic mono-carboxylic acid may be added to the treated coal before it is briquetted. In an example 1000 g. of coal were ground to an average particle size of 0.15 mm., heated to 100‹ C. and sprayed with 22 cc. of 80% acetic acid. After thorough mixing the resulting mass was briquetted. Specifications 798,828 and 798,829 are referred to.

Title: Improvements relating to electric regulators
IPC: H02P9/22
Filed: 1919-11-11
Abstract: 146,033. White, A. E., (U.S. Light & Heat Corporation). Nov. 11, 1919. Regulation, automatic apparatus for.-Relates to electro-magnetic regulators of the type that operate by varying resistance in proportion to the extent of movement of armatures or the like. The mvention consists in providing two armatures, one responsive to small or sudden variations of current, the other responsive to great or sustained variations together with a variable resistance device subject to the joint control of both armatures. The object is to obtain a dead-beat effect without impairing sensitiveness. In one form, Figs. 1 and 2, a compressible carbon pile 10 is compressed, and therefore has its resistance varied, to a greater or less extent, under the influence of a pivoted lever 7 carrying an armature 6. The lever is restrained by a spring 11 and damped by a dash-pot 12 and the armature is made with inclined faces co-operating with inclined stationary poles 1, so that the response to current variation in the electro-magnet 2 is slow and comparatively wide in range. An undamped and more sensitive armature 3, in responding quickly to current variations, strengthens the magnetic flux in the field of the magnet 2 and thereby assists in obtaining a dead-beat and certain effect. The armature 6 may be provided with magnetic adjusting members 24 which can be bent so as to increase or decrease the magnetic reluctance. In a modification, the light quick acting armature, instead of acting solely by strengthening the magnetic flux, has an extension which compresses the variable resistance.

Title: P.A.L. Colour Test Signal Generator.
Inventor: SCADENG PETER
IPC: H04N17/04
Filed: 1966-05-13
Abstract: 1,186,163. Colour television; automatic phase control systems. R.C.A. CORPORATION. 3 May, 1967 [13 May, 1966; 22 June, 1966], Nos. 21360/66 and 27947/66. Headings H3A and H4F. A signal suitable for testing P.A.L. receivers is produced by generating two phase-locked signals at frequencies F1 and F2, where F1 equals the colour sub-carrier frequency f sc  minus the line scan freqency F H  and F2 equals the frequency f sc  plus line scan frequency F H , and applying the signals to the receiver alternately at line scan frequency. With reference to the receiver local demodulation signal at frequency f sc  the signals Fl and F2 appear as signals which undergo a phase change of 360 degrees during the period of one line, the phase change being in opposite directions for the two signals so that the phase modulation appears to change in direction in alternate lines in accordance with the P.A.L. method of operation. The signals Fl and F2 may be produced by means by crystal oscillators 1 and 2, the signal Fl being passed through a gate which is operated at the beginning of lines at frequency F H  (or alternatively at a frequency 2 F H ) to produce side-band signals including a signal at F1 + 2F H  which phase locks oscillator 2 with the aid of control system 4. The signals are selected alternately at line frequency by switch 5. In an alternative arrangement (not described in detail) a circuit selects the side-band at frequency F1 + 2F H  from the output of gate 3 and oscillator 2 is dispensed with. The signal 6 from switch 5 may be combined with scanning synchronizing signals and blanked in a manner such that a receiver displays the signal as a pattern of bars. No separate colour synchronizing " burst " is provided. A receiver " burst " gating circuit responds to signals F1 and F2 at the commencement of lines (when the phases are equal due to the phase lock operation) and produces a side band signal at frequency f sc  to synchronize the local demodulation oscillator. A " swinging burst " (i.e. a " burst " alternating Œ45 degrees in successive lines with respect a reference axis) may be simulated by displacing F1 and F2 by 90 degrees. At the commencement of lines the receiver " burst " gating circuit will then provide a synchronizing signal which changes by 90 degrees in successive lines. The automatic phase control circuit will lock the local demodulation oscillator at the mean phase and produce a correction signal going positive and negative in alternative lines. This correction signal functions as the P.A.L. phase switching signal in the same manner as when the receiver responds to a standard signal.
