Title: Mechanical hydraulic auxiliary control device for aircraft
IPC: B64C29/00
Filed: 1964-08-04
Abstract: 1,071,186. Controlling aircraft. BÍLKOW G.m.b.H. Aug. 4, 1964 [July 23, 1963], No. 30825/64. Heading B7G. [Also in Division G3] An aircraft control linkage, e.g. for controlling the engine of a VTOL aircraft in hovering flight, comprises input and output rods 8, 15 respectively, and levers 1, 2 connected by a rod 3. The fulcrum 13 of the lever 2 is fixed, and the fulcrum 10 of the lever 1 is mounted on a piston rod 51 fixed to a piston 52 movable after a time delay, in response to movements of lever 1, to move the output rod 15 towards its former position. Thus, the displacement of the rod 15 reaches a maximum and then reduces to a steady value which is a fraction of the maximum (Fig. 3, not shown). Each side 34, 35 of the piston is connected to a source of pressure fluid through restrictions 36, 37 and to nozzles 32, 33 the effective areas of which are varied by a baffle 31, which may be in the form of a leaf spring, connected by a rod 30 and links 42, 44, 47 to the lever 1. Thus, when the lever 1 is moved by the rod 8, movement of the baffle differentially varies the pressures in the chambers 34, 35 and the piston 52 moves the fulcrum 10 until the baffle is centralized. The baffle may alternatively consist of a leaf spring built in at its centre (Fig. 5, not shown), having at each end a nozzle, a spring connecting it by a double bell crank to the rod 30, and a spring connecting it to the housing 40 and adjustable to vary the time delay. In another embodiment (Fig. 4, not shown), the baffle is of part-triangular section and is slidable along its base on rollers the nozzles, which are adjustable to vary the time delay, impinging on the sides of the triangle. A locking device 4, disclosed in Specification 966,367, allows movement of the lever 1 to be transmitted to the lever 2, but not vice versa. A further locking device 20 comprises a piston 23 with a projection 24 which on the loss of fluid pressure engages a groove 25 in the piston rod 51 and holds the fulcrum 10 fixed.

Abstract: 767,188. Protective cut-out systems. GENERAL ELECTRIC CO. Ltd. Dec. 9, 1953 [Dec. 9, 1952], No. 31186/52. Class 38(5) In order to render a circulating-current protective system for a power transformer immune to operation by magnetizing currents and through-faults, a variableimpedance circuit is employed which is applied to transformers arranged in the circulating-current circuits so as to lower the output to the protective relays. The Figure shows the arrangement for one of the phases of a delta-star transformer, the primary 14 of a load-bias transformer 21 in one of the circulating-current lines being connected through the primary 17 of a differential-circuit transformer to the star point of the line current transformer on the delta side of the power transformer. The secondary 24 supplies an input winding 2 of a transformer 1 in a circuit tuned to the supply frequency, and also a bridge rectifier 33 in. a circuit tuned to the second harmonic of that frequency. A control winding 4 of transformer 1 is connected across an impedance 5 and in series with a pair of opposed rectifiers 6, 7. The secondary 20, of transformer 21 supplies a bridge rectifier 22 which is connected in the same sense as 33 between the midpoint of 5 and the rectifiers 6, 7. An output winding 3 of transformer 1 supplies the protective relay 27. On through-fault, the rectifiers 22, or on magnetizing inrush, the rectifiers 33, supply a D.C. component to lower the impedance of the variableimpedance circuit, and therefore the output from the winding 3 to the protective relay 27. The Specification refers also to feeding a single control circuit by summation transformers from all three phases, to combining the windings 4, 5 into a single winding, and to connecting the control circuit across the A.C. input terminals of a bridge rectifier.

Title: Improvements in or relating to cardiophone arrangements
Inventor: MORTLEY WILFRED LINDEN
IPC: A61B5/024
Filed: 1963-08-09
Abstract: 1,008,027. Stethoscopes; microphones; radio signalling. MARCONI CO. Ltd. July 30, 1964 [Aug. 9, 1963], No. 31470/63. Headings H4J and H4L. In a cardiophone the output from a microphone is translated into a frequency modulated carrier signal and this signal is translated into a correspondingly frequency modulated sound wave having its mid-frequency in a sensitive part of the spectrum of human hearing. A capacitor microphone 3 (Fig. 1), designed to pick up foetal heart-beat sounds in the range 5 to 50 c/s. forms part of a frequency determining resonant circuit 2 which, together with a transistor 1, acts as a generator with a mid-frequency of between 800 and 1,200 c/s. Frequency modulated oscillations produced by variations of the amplitude of response of the microphone 3 are fed to a unit 4 including low power amplifying and radio transmitting apparatus. A capacity or loop aerials may be used. An apparatus 7 recovers the frequency modulated wave and applies it to a loud-speaker or headphones 8. The frequency modulated carrier signal and the frequency modulated sound wave may be of the same or different frequency. The mid-frequency of the sound wave may be adjusted by a heterodyne circuit. The radio link may be replaced by a flexible connector. Alternatively, the microphone, generator and sound reproducer may be a single unit adapted to be placed on a patient. Where the apparatus is in two parts the transmitting link may be a supersonic sound wave channel or an audible sound wave channel. Risk of " howling " is reduced by the arrangement and may be further reduced by filtering. Microphone.-An inertia controlled capacitor microphone is used and includes a fixed electrode plate 32 (Fig. 2) and a movable electrode 36. The electrode 36 is secured on a heavy cylinder 37 supported in a cylindrical casing 31 by springs 38. The resonance frequency of the cylinder 37 with its springs 38 is a few cycles per second and is critically damped by air flow friction between the cylinder 37 and casing 31. Alternatively, electrical or mechanical damping may be used. Eddy current damping may be obtained by making the cylinder 37, or part of of it, in the form of a magnet the field of which penetrates the outer cylinder 31, A stem 33, insulation 34 and a collar 35 form a socket to receive a plug (not shown).

Abstract: 754,917. Electric indicating systems. DAIMLER-BENZ AKT.-GES. Nov. 1, 1954 [Nov. 4, 1953], No. 31549/54. Class 40(1) The stroke of the nozzleneedle of a needle valve, e.g. a fuel injection nozzle in an I.C. engine, is measured by varying an inductance or capacitance in accordance with the needle displacement and using the electric variations to operate an indicator. The valve needle 6, Fig. 1, carries at its upper end a plate 7 on which rests the valve biasing spring 8. Secured to the plate 7 is a soft iron plunger 11 having an intermediate non-magnetic e.g. brass, portion 11a, extending into coils 10 disposed within a pot extension 9a of a fixed spring reaction plate 9 for the spring 8. With the valve closed the non-magnetic portion 11a of the plunger lies substantially between the coils 10 so that movement of the needle causes a differential impedance variation in the coils 10 which is detected in an A.C. bridge circuit Fig. 3 (not shown); the bridge output is amplified. rectified and filtered to operate an oscilloscope in accordance with the needle displacements. A further construction, Fig. 2 (not shown) in which the valve needle opens outwards is described.

Title: Improvements in or relating to an apparatus for filling containers, for example, bottles with carbonated liquid
IPC: B67C3/06
Filed: 1947-12-01
Abstract: 650,702. Bottling-machines. STEVENS, A. H. (Liquid Carbonic Corporation.). Dec. 1, 1947, No. 31680. [Class 125(ii)] A container filling machine, e.g. for bottling carbonated beverages, comprises a valve admitting liquid to the container when sealed under pressure control of fluid .also admitted and a secondary valve for cutting off fluid flow to the container and valve operating means whilst gradually venting the top of the container before it is unsealed. A ring-shaped rotary bottle filling tank 1 with filling valves 2 surrounds a liquid check tank 3 containing an open-bottomed cylinder 4 into which air under pressure is introduced maintaining a predetermined liquid level in the tanks 1, 3. A bottle is raised by mechanism (not shown) to engage the gasket 32 of a receiving belt 31 which then slides up a filling tube 13; the depending stud 25 of an annular valve 22 is thus lifted and by engagement of the top of the bell with a gasket 28 the bottle is placed into communication through a chamber 21 of the filling valve and passages 24, 35, of a control valve housing 34 with a pipe 6 leading to cylinder 4. Air under pressure is also transmitted through pipes 17 to a space 19 thus depressing a diaphragm 18 supporting the stem 15 of a liquid delivery valve 14 at the end of the filling tube 13 so that liquid is discharged into the bottle. By the time the bottle has been filled to a level determined by the level maintained in tank 3, the tank has reached a position in which the outer end of the control valve stem is engaged by an arcuate cam 51 which closes the valve and cuts off the pressure cylinder from space 21 and the bottle. Also, movement of the valve stem has removed the rear face of the valve from a seat 43 and brought passage 24, and thereby space 21 and the bottle, into communication with atmosphere through valve stem passages 48<SP>1</SP>, 47, 48 a channel 41 and a bleeder port. The liquid valve 14 accordingly closes and when the bottle is unsealed the pressure within has already dropped sufficiently to obviate foaming.

Title: Artificial pyrolusite and its use in batteries
IPC: C01G45/02
Filed: 1962-08-17
Abstract: Artificial pyrolusites, i.e. those obtained by precipitation from a manganese salt solution by means of an oxidizing or reducing agent, especially suitable for use in the construction of Leclanche cells, are dehydrated to a water content of 15 to 35%, preferably 20 to 23%, while being continuously mixed and/or divided, as e.g. in a drum drier and preferably with a grinding agent, at a temperature not exceeding 150 DEG  C. and preferably above 65 DEG  C.  The dehydration may be effected under subatmospheric pressures and lower temperatures.  In a modification of the process, a pyrolusite which had its water content reduced to less than 15% may be steam-treated or water vapour-treated to obtain the product containing 15 to 35% water.  A preferred starting material is obtained by oxidizing at pH 5 to 9, an aqueous solution of a bivalent manganese salt with chlorine or hypochlorite.  The product of the invention may be admixed with natural or electrolytic pyrolusite. In the example, which includes for comparison static dehydration of pyrolusite in an oven on trays to an identical water content, use is made of a rotary drum drier charged with porcelain balls.  Specification 939,240 is referred to.
