Title: Improvements in or relating to bobbin tube cages
Inventor: GLAZENER C
IPC: B65H67/06
Filed: 1970-08-21
Abstract: 1286042 Bobbin handling means MAREMONT CORP 21 Aug 1970 [13 Oct 1969] 40338/70 Heading D1F A bobbin tube cage 10 comprises an elongate cage member for the reception of a bobbin therein in an on-end position, the cage member being formed with an open top, through which the on-end bobbin passes, a partially closed bottom, rigidly fixed on said member, on which the bobbin rests, and an open side extending between the top and bottom and through which the bobbin is passed on withdrawal in an on-end position, guide means being provided for guiding the bobbin into the cage member, retaining the bobbin therein and guiding the bobbin for on-end withdrawal from the cage member. The cage member is formed of a back wall 32 and facing side walls 34, 36, the wall 34 preferably extending further from the back wall than the other side wall 36. The partially closed bottom of the cage member is formed by projecting flanges 30 on the side walls 34, 36. The open top of the cage member is preferably flared at 26 for ease of reception of the bobbin. A guide plate 38 is provided between the side walls 34, 36 across the top of the open side of the cage member, which guide plate 38 serves to maintain the bobbin in an upright position and prevent tilting forward of the bobbin during removal thereof from the cage member. A gate 44 movable between a closed end and an open position is hingedly mounted on the side wall 36, and is biassed into the closed position in which it partly covers the open side of the cage member. In operation, an empty or full bobbin is slid down a chute into the cage member and is supported on the flanges 30 and retained in the cage member by the guide plate 38 and gate 44. The cage member is then moved laterally from a position beneath the said chute to a position adjacent the end of an endless conveyor which is provided with spaced projection pegs. A peg projects through the partially closed bottom of the cage member and into the base of the bobbin therein. The movement of the conveyor causes the bobbin to be withdrawn from the cage member through the open side thereof against the action of the spring-loaded gate. The gate is preferably formed with a smooth convex edge portion 46 to facilitate withdrawal of the bobbin.

Title: Apparatus for x-ray analysis
IPC: G01N23/20
Filed: 1972-08-31
Abstract: 1382649 X-ray spectrometers NIHON DENSHI KK 31 Aug 1972 [10 Sept 1971] 40507/72 Heading G1A [Also in Division H3]  In an x-ray spectrometer in which x-rays diffracted by rotating crystal are received by an x-ray counter rotating at twice the speed of the crystal and means are provided for maintaining constant the mean height of pulses produced by x-rays satisfying the Bragg equation, a pulse height analyzer is provided having a base line and a window width which are varied in accordance with the angle of rotation of the crystal. As shown, Fig. 2, a sample 2 is irradiated by x-ray source 1 and fluoresces producing x-rays which are reflected from a crystal diffractor 4 and received by a detector 5. The crystal 4 is rotated by means of a drive 7 and the detector 5 is also rotated but at double the speed. The output of the detector is applied to a preamplifier 8 and then to an amplifier 9 whose gain is varied by a reference signal from the drive 7 proportional to the cosecant of the angle between the incident ray and the surface of the crystal to produce an output in which the pulses produced by x-rays satisfying the Bragg equation have a constant mean height. However the pulse heights vary about the mean value with a Gausian distribution the width of which is also a function of the angular position of the crystal and the pulses are therefore applied to a height analyzer comprising a lower threshold clipper 10 and an upper threshold clipper 11 the thresholds of both of which are controlled by a potentiometer 15 coupled to the crystal drive. The outputs of the clippers 10 and 11 are applied to an Exclusive OR gate 12 so that only pulses with heights between the threshold levels are passed to a counter 13 and recorder 14. As shown, Fig. 3, each clipper comprises a diode 23, 26 reverse biased by means of a reference voltage source 20, 29 and a voltage derived from the potentiometer 15 which varies in proportion to #sin#, where # is the angle between the incident ray and the surface of the crystal. Pulses with a height greater than the sum of the respective reverse bias and the forward threshold voltage of the diode are passed to the output of the clipper. The first clipper 10 provides a base line which decreases with increasing angle whereas the second clipper 11 provides an upper window edge which increases with increasing angle so that the effective window width increases symmetrically about the constant mean pulse height with increasing angle. Instead of using a variable gain amplifier 9 to maintain constant the mean pulse height the detector sensitivity may be varied by controlling the high voltage supply as described in Specification (Serial No 1380594).

Filed: 1970-08-26
Abstract: 1324526 Nucleating molten metal HOWMET CORP 26 Aug 1970 [2 Sept 1969] 40923/70 Heading B3F To form a fine-grained alloy casting, a charge of alloy of the volume less than that required to fill a mould is melted and maintained above the liquidus temperature of the alloy to equalize the temperature throughout the molten alloy charge. A slug of a nucleating substance is added to the charge. The nucleating substance may be of the same composition as the molten alloy charge or may contain only some of the components of the molten alloy charge. As the slug melts the temperature of the molten alloy charge is reduced the charge volume increases and nuclei are formed. The charge may be stirred e.g. electromagnetically when induction melting. The charge is poured into the mould which may be preheated and the unmelted part of the nucleating slug held in the molten alloy charge to provide a source of nuclei throughout the pouring operation.

Title: Pulse compressor system
IPC: H03H7/30
Filed: 1962-10-30
Abstract: 1,236,201. Pulse radar. COMPAGNIE FRANCAISE THOMSON-HOUSTON. 30 Oct., 1962 [2 Nov., 1961], No. 41098/62. Heading H4D. In a frequency modulated pulse-radar receiver, pulse compression is employed. Several similar parallel channels are provided, each having a frequency converter associated with a local frequency oscillator, a filter, a dispersive unit to compress the signal, a delay network and a frequency converter. The frequencies of the channel local oscillators are related arithmetically and the received signal is split into several narrow band components. The delay line retards the signal in each channel sufficiently to cause the separate channel signals to add finally to form a complete narrow pulse. Each of the filters is designed to produce a linear phase displacement-frequency response and the system thus provides for each echo pulse a delay which is linear with frequency. It is demonstrated vectorially that the final addition of the outputs of separate channels itself produces a time compression. The addition is effected at the centre of each time interval of all the outputs when the signals are co-phased. Prior and subsequent to this instant the vectors, being of different frequencies, rotate relative to each other and thus reduce the sum signal.

Title: Improved method of and installation for electrostatic spray painting
IPC: B05B5/04
Filed: 1958-12-23
Abstract: Workpieces are painted by establishing an electric field between a paint distributer and the workpiece, electrostatically atomizing and charging the paint as it leaves the distributer, and then introducing substantially all the paint particles into an air stream flowing parallel to the electric field between the distributer and workpiece and towards the workpiece.  As shown, paint is poured from a pipe 42 into a cup 40 whence it flows on to the upper surface of a stationary plate 36, charged to a high electrical potential by a source 44.  The <PICT:0846063/III/1> paint is charged and atomized as it flows over the sharp edge 38 of the plate, the particles being drawn downwardly into the air stream produced by a squirrel cage rotor 50, which is mounted on an insulating shaft and rotated by a motor 30.  In order to control the spray pattern, the louvres 54 of the rotor may be inclined to the vertical, or may be of herringbone design, and p  the apices of the differently inclined parts may be in one plane or may undulate around the rotor.  The workpieces 22 are carried on a conveyer 26 connected to the opposite pole of the source 44; the conveyer may provide a square path surrounding the distributer, the corners being outside the spray pattern.  In a modification, a semicircular shield, connected to the source 44, may be provided adjacent the external surface of the rotor.

Abstract: 1330216 Treatment of grain; thrashing machines MATTI GUNNAR WILSKA 9 Sept 1971 [10 Sept 1970] 42059/71 Headings A1F and A2D [Also in Division B1] An applicator for applying a liquid to a granular solid comprises a vessel through which this solid passes and means to regulate the flow of the granular solid, the vessel being so constructed that when granular solid is flowing therethrough at least a portion of the granular solid transfers kinetic energy to the vessel, the energy thus absorbed by the vessel controlling the means to regulate the liquid flow. A section of a suitable applicator is shown in Fig 2 wherein there is provided a mixing vessel 22 having inclined surfaces 2 positioned about the sleeve 3, this sleeve being movable vertically about pipe 21. Liquid passes along pipes 5 and 21 and out of holes 1 into into the mixing vessel. This vessel is fixed to the arm 4 which is pivoted at 11, the vessel being counter balanced by weight 7. A spring 9 further urges the mixing vessel upwards so as to cover the holes 1. When granular solid is supplied via the outlet screw 18 to the mixing vessel, the kinetic energy of this solid forces the vessel downwards thus uncovering more holes 1 and hence permitting more liquid to impinge upon granular solid in the mixing vessel. This vessel has an open bottom permitting treated granular solid to fall into collecting means. The invention is particularly applicable to the treatment with a preserving liquid, i.e. propionic acid, of grain.
