Abstract: 1,053,159. Hydrocyclones. R. ZEMANEK, J. FELLEGI and J. JANCI. July 20, 1965 [Feb. 4, 1965; Feb. 18, 1965], No. 30825/65. Heading B2P. Large fibrous impurities are separated from acceptable fibres in a liquid suspension of the fibres by forcing the suspension to flow as a vortex about an air core so as to cause the acceptable fibres to segregate in the outer part of the vortex and the impurities in the inner part thereof, and separating the inner part of the vortex together with the air core from the outer part of the vortex. The process is carried out in a hydrocyclone comprising a vessel with coaxially mounted inner and outer vortex finders and in which the length of the vessel is at least seven times its maximum internal diameter. In the embodiment of Fig. 1, the suspension is fed tangentially through a pipe 8 into the cylindrical part of a vessel which has a conical part 3a provided with a discharge opening for heavy impurities. The air core and the unwanted fibrous impurities are discharged through a vortex finder 7 while the acceptable fibres pass through the vortex finder 6 into a collecting chamber 10 formed above a partition 5 and are discharged through a pipe 9 having an adjustable throttle valve. The vortex finders 6, 7 may be axially adjustable and their lower ends may be at different levels. In a modification, Fig. 2 (not shown), the lower portions 17, 18 of the vortex finders are frusto-conical. In a further modification, Fig. 5 (not shown), the partition 5 is dispensed with and the outer vortex finder 206 projects vertically through the top of the vessel and has a throttle valve 213 whereas the inner vortex finder has a lower portion coaxial with the outer vortex finder and an acuate upper portion extending through the wall of the outer vortex finder. The vessel may be wholly conical, Fig. 4 (not shown). In a still further modification, Fig. 7 (not shown), an annular outer vortex finder 27 surrounds the inner vortex finder 307 with clearance and discharges into a collecting chamber 310. The intake to the outer air vortex finder is at a radial distance from the vessel axis corresponding to the region having the highest concentration of acceptable fibres. A two-stage separator system, Fig. 6 (not shown), consists of a first hydrocyclone of the kind shown in Fig. 1 having its dishcharge pipe 9 connected to the tangential inlet pipe 8" of a second hydrocyclone 20 of cylindrical shape and closed at the bottom. Further separation between the wanted and unwanted fibres takes place in the hydrocyclone 20. Dimensions of the various parts are given.

Abstract: 1,227,155. Fluid pressure servomotor systems. SCANS ASSOCIATES Inc. Aug. 20, 1968 [Sept. 14, 1967], No.39738/68. Heading G3P. Apparatus for testing carburetters comprises devices for continuously measuring the rates of flow of air and fuel through the carburetter under test, and a device for continuously dividing these rates and giving an indication of the mixture ratio. A test bed Figs. 1-3 (not shown) has means for temporarily attaching a carburetter 22 under test to a chamber 20 connected to a vacuum pump 28 by a selected one of a set of interchangeable critical flow Venturi tubes 24 which produces an air flow corresponding with a desired one of a series of engine operating conditions between "idling" and "full throttle". A reference table, set out in the body of the Specification, is then consulted to determine the pressure which should exist in an engine intake manifold for this air flow and the butterfly spindle 57 adjusted accordingly. This adjustment can be effected automatically for similar carburetters operating at the same airflow by a pneumatic thruster 30 opposite ends of which are fed with a reference pressure via line 40 and adjustable pressure regulator 42 from a source 41, and through line 43,with a pressure generated in a device 45 to correspond with the air-flow rate. Device 45 also feeds a force bridge computer 72 which is also fed with a signal generated in an amplifier 64 connected to a mass flow meter 62 measuring the rate of fuel flowing through line 61. The output of computer 72 is connected to pressure gauge 73 calibrated in terms of mixture ratio. A suitable dial for this gauge is illustrated in Fig. 9 (not shown) and the apparatus may be provided with lamps which are illuminated when the mixture ratio is outside acceptable limits. The mixture is continuously drained from chamber 20 and the fuel is reclaimed from it by the device illustrated in Figs. 12, 13 (not shown). In various modifications (not shown) chamber 20 is provided with a nest of four Venturi tubes, each corresponding with a different air-flow rate, and four valves are provided to render selected tubes operative. This apparatus also has a set of four selectively operable pressure regulators, corresponding with regulator 42, and either four mixture ratio gauges, or a single gauge calibrated as in Fig. 14 (not shown), so that readings can be taken for each of four engine operating conditions by operating a set of control valves which connect the selected Venturi tubes and pressure regulators in circuit. In another modification Fig. 16 (not shown) the carburetter is tested directly on an I. C. engine so that chamber 20 and its ancillary equipment can be dispensed with. In a further modification Fig. 15 (not shown) the flow rates are converted into electrical signals which are fed to an electrical analogue computer feeding a voltmeter having mixture ratio calibrations.

Abstract: 1,230,879. Semi-conductor devices. ITT INDUSTRIES Inc. 5 Dec., 1968 [9 Dec., 1967], No. 57771/68. Heading H1K. [Also in Division H3] A temperature compensated Zener diode consisting of components formed in a common semiconductor body, comprises more than two transistor structures having a common collector zone, the emitter junctions of the transistors being connected in series such that at least one is reverse biased to form a Zener diode and the remainder are forward biased, at least one of the transistors with its emitter junction forward biased being utilized to reduce the dynamic resistance of the structure. The transistors having forward biased emitter junctions form a Darlington-type configuration, the transistor effect producing the required reduction in dynamic resistance, and may be provided with emitter resistors to increase the individual emitter currents. Since the temperature coefficient of each forward biased junction varies with the current, these emitter resistors may be selected to produce the desired temperature coefficient. The resistors may comprise diffused regions in the integrated circuit or resistive tracks deposited on the surface. A transistor utilized as a forward biased diode and one utilized as a Zener diode may be combined in the form of a double emitter transistor, Fig. 9 (not shown), and the degree of temperature compensation may be controlled by selecting the coupling between the two emitters which together with their common base region may effectively form a lateral-type transistor. Various alternative circuit configurations, some using double-emitter transistors, are described, Figs. 6 to 8 and 10 to 13 (not shown). Reference has been directed by the Comptroller to Specification 1,082,519.

Abstract: 1,233,108. Valves. AUTOMATIC SWITCH CO. 12 Nov., 1968 [3 Jan., 1968], No. 53563/68. Heading F2V. A valve comprises a solenoid 24 with an armature 26, the armature influencing the position of a wedging element 39 whereby balls 38 are caused to intrude the recess 35 in a sleeve 21 slidable relative to the valve body, the intrusion latching the disc carrier 13 and the sleeve 21 together so that the disc 12 can be manually raised by the member 30. A spring 44 interposed between a plug nut 25 and the armature 26 is stronger than the spring 43. Consequently when there is no current through the solenoid the armature 26 is forced to its lower position (Fig. 1) in which the balls 38 are held in a carrier 14. On raising the member 30 the sleeve 21 is not latched to the carrier 14 and so the valve is not opened. When a current passes through the solenoid 24 the armature 26 is raised to its upper position (Fig. 2, not shown), the spring 43 causing the balls 38 to intrude the recess 35. On raising the member 30, the valve is opened. The member 30 can be rotated slightly to hold the valve open, but should the solenoid 24 be subsequently de-energized, the spring 44 forces the wedge 39 downwards to unlatch the carrier 14 and so close the valve. In another arrangement the valve can only be opened when the solenoid is de-energized.
