Abstract: 1404319 Selective signalling DEFENCE SECRETARY OF STATE FOR 24 Nov 1972 [25 Nov 1971] 54812/71 Heading G4H In data signal switching control apparatus, a plurality of gate circuits in respective data input lines are selectively opened by a decoder controlled by a pulse-driven counter, there being a data store presenting one of a sequence of predetermined label words each with an associated predetermined reset word, equality between the count and the presented label word causing the counter to be preset in accordance with the presented reset word and the next label word and reset word to be presented by the store. The gates pass analogue voltages representing, e.g. temperature, pressure, from transducers, to a common A/D converter the output of which is stored in a buffer, as are signals from digital transducers, the buffered values being recorded on a multi-track tape, which also pre-loads the data store holding label and preset words and provides timing signals for the system, e.g. to drive the counter.

Title: Measurement of the eccentricity of the core of coated ferro magnetic rods and wires
IPC: G01B7/312
Filed: 1971-12-13
Abstract: 1368326 Magnetic measuring apparatus HOESCH A G 13 Dec 1971 [16 Jan 1971] 57691/71 Heading G1N In a measuring device for detecting the eccentricity of coated ferromagnetic rods or wires 3 within their coating 4 a magnetic flux passing into, along and out of the wire or rod 3 is divided into partial fluxes by at least three pole shoes 7 spaced circumferentially round the rod or wire 3 and individually measured at the foci 6. In the device shown in the figure the device is positioned round an extrusion nozzle 2 and includes an axially magnetized ring magnet 4, and four pole shoes 7 are spaced 90 degrees apart round the nozzle. As the coated rod is extruded through nozzle 2 magnetic flux flows from magnet 4 through disc shaped pole shoe 9, nozzle 2, rod 3, pole pieces 7 and ring shoe 8 back to the magnet 4. Flux measuring elements such as semi-conductors, resistors Hall effect devices or coils are positioned at respective foci 6 and the difference between two opposite partial fluxes is a measure of the eccentricity of the axis of the core 3 in relation to the axis of nozzle 2. To achieve this the diametrically opposite pairs of measuring elements are connected in two bridge circuits Fig.4 (not shown) one bridge measuring the X direction and the other the Y direction. The bridge outputs may be supplied to a CRT and to a switch which adds the signals vectorially and produces an output corresponding to total eccentricity which may be recorded on a pen recorder. The ring magnet 4 may be replaced by a radially magnetized ring or a coil and the extrusion nozzle may be replaced by a ferromagnetic ring. The invention may be associated with pneumatic, optical or mechanical measuring devices located to operate in the same or substantially the same plane as that in which the magnetic measurement is made and arranged to measure the eccentricity of the coating 4.

Abstract: 1,279,695 Granulating moulding powders PERSTOP AB 27 Nov 1969 58109/69 Heading B5A [Also in Division C3] Moulding powder e.g. melamine or urea resin containing a cellulose filler, is granulated in a container 2 by intermittently introducing a pulse of pressurized air, of 0À5 to 5À0 seconds duration and at intervals of 0À5 to 10 seconds, through an inlet 4 to expand the powder into a turbulent cloud into which granulated liquid e.g. water, is simultaneously sprayed through a nozzle 6. The powder coheres upon settling after the pulses, and this effect may be enhanced by vibrators arranged at the sides of the container 2. The container 2 is provided with a filter 7 and cap 8, with an inlet 3 for powder, and an outlet 5 through which the granules are discharged after drying by warm air introduced into the container 2. The powder may be pre-blended with pigments, catalysts or lubricant, or alternatively these may be added by nozzles or jets within the container, which may be separate from or combined with the pressure air inlet 4, and mixed with the moulding powder prior to the granulating step by introducing pressure air pulses in the absence of the granulating liquid spray. After granulating, the drying, either separately from the container or by introducing warm air thereinto, may be assisted by the preceding introduction to the container of further dry powder which is mixed with the granules by air pulses.

Apparatus for testing the underload performance characteristics of a prime mover comprises a rotary power absorber 2A wherein a retarding action is produced between a stator and a shaft driven by the prime mover, which also drives a tachogenerator 538 to produce an electric signal for transmission to an electrically responsive actuator causing the brake to apply a retarding force corresponding to the speed of the prime mover. The electrically responsive actuator acts electro-magnetically to apply a frictional force between the stator and a rotor on the shaft either through brake shoes or through a medium of ferrous particles and oil, the retarding force varying with the value of the electrical current applied thereto. The current from the tachogenerator 538 may be applied to the generator through a rheostat 552 to apply a retarding force directly proportional to speed and the ratio of proportionality can be set by adjusting the sweep arm 550. Alternatively an amplifier 556 can be introduced as shown, whereby the retarding force can be made to vary according to a preselected function of speed e.g. the square of the speed by using a sutiably constructed power amplifier.
