Abstract: 1384899 Measuring density and mass flow electrically MERESTECHNIKAI KOZPONTI KUTATO LABORATORIUM 6 July 1972 [7 Dec 1971] 31813/72 Heading G1N A sensor for determining the density of a flowing fluid comprises a measuring cylinder 2 whose natural frequency of vibration depends on the density of the fluid flowing therethrough, a reference cylinder 3 in a sealed chamber 8a and having a preadjustable fixed natural frequency, which corresponds to that in cylinder 2 when that contains a vacuum means for setting the cylinders in vibration, and means for determining the difference frequency. As described the arrangement is calibrated by allowing some fluid into chamber 8a until the frequencies of the cylinders are the same for a vacuum in cylinder 2. The chamber 8a is then sealed. The two cylinders are in good thermal relationship and adopt the same temperature Exciter heads 4, 5, which may be electromagnetic, magnetostrictive, or capacitative, set up vibrations which are sensed by sensors 6, 7, the outputs being fed to amplifiers 12a, 12b, whose outputs drive the exciters 4, 5 thereby forming closed loops. The outputs of the amplifiers are mixed at 13 giving a difference frequency which may be shaped at 14, and this signal at 19 may be fed to a frequency-to-current converter 15 to give an analogue output which may be read on a meter Fig.3 (not shown). The difference frequency signal 19 may be transmitted by telephone or telegraph before conversion Fig.4 (not shown). To determine rate of mass flow the output signal may be multiplied by a signal indicitive of rate of volume flow obtained from a turbine flow meter Fig. 5 (not shown). The difference frequency signal 19 may be fed directly to a digital frequency meter Fig. 7 (not shown), whose "clock" reference signals may be derived from the reference cylinder output.

Title: Improvements in or relating to filters
Filed: 1938-11-03
Abstract: 520,298. Filters. AUTOMOTIVE PRODUCTS CO., Ltd., and POOLE, L. A. Nov. 3, 1938, No. 31889. [Class 46]  In an edge filter formed of a coil of wire or ribbon the coil is supported between relatively movable end members on a former and is normally held in position of minimum spacing by a spring retaining means being provided to hold the end members in a position of greater spacing. As shown in Fig 1, a coil 10 is wound on external longitudinal ribs of a cylindrical former which consists of two parts 11, 12, the part 11 being attached to an end cap 25, seating in a central recess 32 in the head 8 of the housing 26 while the part 12 is fixed in a short sleeve 23, attached to a plate 24 which closes the other end of the housing. A stem 34 fixed to the plate 24 extends through the head 8 and receives a wing nut 36. A spring 44, bearing at one end against a shoulder on the stem 34 and at the other against an internal shoulder on a sleeve 41 formed integrally with a cap 25, draws the two parts of the former together and maintains the minimum spacing of the coil. The parts 11, 12 have longitudinally projecting fingers, 15, 16, normally fitting between one another. When the filter requires cleaning, the nut 36 is removed and the filter drawn out of the housing on the plate 24. The coil is then extended by pulling apart the head 25 and the plate 24 againstthe action of the spring to a position in which, on relative rotation of the parts of the former, V-shaped projections at the ends of the fingers 15 can be engaged in similarly shaped recesses at the ends of the fingers 16, as shown in Fig. 2. The coil is thus held in the external position. Stops are provided on the parts of the former to limit their rotational movement.. The liquid enters the housing through a connection 28 and the filtrate is discharged through a connection 31. In the filter shown in Fig. 4 the former 50 is cast integral with the head 51 of the housing and the lower end of the coil is attached to a ring 66 carried by an end cap 58. The end cap is drawn up by a spring 62 which surrounds a stem 57 fixed to the, cap 58 and bears against a cross-bar 61 on the stem and against a plug 64 screwed into the end of the former. When the end cap is drawn down the crossbar 61 passes through gaps in a flange 63 on the former and, on rotation, engages beneath the flange, so that the coil is held extended for cleansing. The coils may be made as described in Specification 385,755.

Abstract: 506,386. Thermionic valves. M-0 VALVE CO., Ltd., HALL, T. F. B., and SMITH, H.S. Nov. 24, 1937, No. 32347. [Class 39 (i)] An insulating spacing means for the elements of an electrode system of a thermionic valve comprises two portions, one being provided with holes, each adapted to locate one of the support wires for said elements, all support wires of the said system being so located, and with at least one notch or slot for receiving the cathode, the other portion being adapted to pivot about one support wire relatively to the first portion and having a number of notches or slots adapted to cooperate with the holes and notches or slots in the first portion to provide locations for the cathode and support wires. In the form shown, two mica plates 3, 4 have holes and slots through which pass the grid support wires 10, 10a, 11, 11a, a filamentary cathode and the pinch wires 8, 9. The plate 4 is cut away in a central W which co-operates with a central cutaway portion 12 in the plate 3 to form triangular locating holes for the filament wires. A bent wire 14 passes through holes 15 in both micas and is welded to the pinch wire 9, locking the insulating plates 3, 4 together. The grid supports and the cathode are therefore located by the locked micas 3, 4.

Abstract: 720,000. Control of D.C. motors. GENERAL ELECTRIC CO. Dec. 22, 1952 [Dec. 28, 1951], No. 32444/52. Class 38(3) [Also in Group XXXV] A hoist is driven by a compound wound D.C. motor 2 having a series field winding 2b and a shunt field winding 2c. A generator 5 for supplying the motor with variable voltage is driven at constant speed by an induction motor 6 which also drives a machine 11 for exciting the generator field winding 5b. The shunt field winding 2c of the motor is supplied from the exciter and is poled so that its magnetization is added to that of the series field winding 2b during motoring operation in the hoisting direction. A rectifier 17 is connected in parallel with the winding 2b to prevent demagnetization of the hoist motor during regenerative braking in the hoisting direction or during motoring operation in the lowering direction, the rectifier acting as a by-pass for the series field winding so that its magnetization affords no substantial opposition to that due to the shunt field winding 2c. There will be a slight voltagedrop across the rectifier 17 when it passes current. A resistor 18 is therefore connected in series with the winding 2b to reduce the field current to a negligible value. The direction of rotation of the motor and the strength of the generator field winding 5b is controlled by a master switch 12 which regulates resistor 19 in series with exciter 11. In the " off " position of the controller the field winding 5b is connected across the armature of the generator.
