Title: Improvements in or relating to loose-leaf post binders
IPC: B42F13/12
Filed: 1944-08-21
Abstract: 577,732. Loose-leaf binders. GILBERT & SONS, Ltd., A., and GILBERT, A. Aug. 21, 1944, No. 15925. [Class 146 (i)] In a loose-leaf post binder each binding post is attached tc one of the binding bars by an end section or stud which is rotatably and captively carried by the bar. As shown, the covers 2, 3 are fixed to binding bars 15, 4. In the upper binding bar 4 is non-rotatably re cessed a nut 6, internally screwthreaded to receive the threadec spigot 7 of the uppermost section of the binding post carrying a washer 12. The lower binding bar 15 houses a stud 16 which has a flat head 17 slotted for a screw-driver or the like, and screw-threaded to engage the hollow internally screw-threaded part of the lowermost section of the binding post. A flange 18 of greater diameter than the aperture 20 is recessed into the binding bar to retain the head 17. In a modification, the head 17 is of greater diameter than the binding post and the flange is omitted.

Title: Improvements in or relating to automatic control systems for ward-leonard generators
IPC: H02P7/34
Filed: 1954-05-31
Abstract: 771,604. Automatic speed control systems. IGRANIC ELECTRIC CO., Ltd. May 31, 1954 [June 5, 1953], No. 16056/54. Class 38 (4). The invention relates to a reversible Ward- Leonard drive using magnetic amplifiers to provide automatic speed (voltage) control and current limiting over-ride, whereby the motor runs at constant limited current during transient conditions of starting and reversing, and then runs under automatic speed (voltage) control. Speed control.-As shown, a motor M is supplied by a generator G having forward and reverse fields 9, 10 energized respectively through two-stage self-saturating magnetic amplifiers MAF, MVF and MAR, MVR. Considering the " forward " control MVF has (i) a reference winding 29 energized from bus-bars 33, 34, whose polarity is reversible by a switch 56; (ii) a control winding 30 connected to the generator G through a polarity-selecting rectifier 35; and (iii) a bias winding energized from the supply L1, L2. The output of MVF supplies the control winding 22 of MAF which also has a bias winding 23 and current control winding 24 (described below). The reverse control amplifiers MVR, MAR are similarly connected, and according to the direction of the reference voltage as determined by switch 56 one set of amplifiers will be cut off, and the other will be operative to maintain the effect of the generator energized winding equal and opposite to the combined effect of the reference and bias windings. Current control.-Amplifiers MCF, MCR are normally biased to cut-off by windings 64, 70 until the loop current in the forward or reverse direction (as detected by the I.R. drop across resistance 11 applied to windings 63, 69), exceeds a predetermined limit, when either MCF or MCR operates to energize windings 24 or 44 in the second stage of the speed control amplifiers whereby the excitation is reduced to limit the loop-current. The specification states that the use of a resistor 13 in the common field supply lead considerably reduces transient induced currents in the inoperative field circuit.

Title: Process for the preparation of granular uraniferous material
IPC: G21C3/62
Filed: 1959-05-12
Abstract: A granular uraniferous material, suitable for use in a nuclear reactor, is prepared by forming a homogeneous aqueous solution, at least substantially free of precipitation nuclei, containing nitrate ions, preferably in concentration below 1,8 gram ions/litre, from 0,2 to 0,6 gram ions/litre of urea, and maintaining the solution at an elevated temperature not above 100 DEG C., preferably between 90 DEG and 98 DEG C., so that uraniferous material precipitates, the solution being subjected before and during the precipitation to the action of a mixer or agitator, preferably a high frequency vibratory mixer, for example as described in Specification 682,946, by means of which shearing forces of high magnitude, and distributed throughout the solution, are generated, the precipitate being separated from the hot liquid in the form of the fine particles in which it forms.  The product may be reduced by means of hydrogen to give uranium dioxide, which may then be sintered in an atmosphere of water-containing hydrogen such that the individual particles are not enlarged by adhesion.  In an example, the precipitate was water-washed and then dried with acetone, to give a noncrystalline solid having a particle size distribution with an extremely sharp maximum at about 13 microns and a maximum standard deviation of 3 microns.  The product may be reduced in hydrogen at 1000 DEG -1200 DEG C. and then sintered at 1700 DEG C. in a hydrogen-water atmosphere, to give a uranium dioxide having a particle size distribution as above but with an extremely sharp maximum at about 9 microns, and with a very small specific surface area (0,05 to 0,10 m2/gram).  Specifications 753,339 and 785,997 also are referred to.

Abstract: 392,748. Cooling or heating oil. HEPWORTH, F., Summerfield, Waterloo Road, South Yardley, Birmingham. June 9, 1932, No. 16319. [Classes 29 and 64 (i).] A heat-exchanger, such as an oil cooler, comprises a housing containing a removable tube unit 5 and means, such as a partition 8, to cause fluid in the housing flowing outside the tubes to pass at least twice lengthwise of the apparatus so that the inlet 2 and outlet 4 are brought into proximity, and a pressure relief device is provided to byepass the fluid from the inlet to the outlet. The byepass comprises a disc 13 pressed against the end of partition 8 by a spring 17. A passage 18 is provided to render the pressure at the back of disc equal to that on the outlet side of the apparatus. When the pressure on the inlet side is sufficient, or when a manually-controlled screw, (not shown) is operated the disc 13 compresses spring 17 and allows liquid to flow round the end of partition 8 from inlet to outlet. When the byepass disc is removed by unscrewing the head 15, the aperture left serves for inspection purposes.

Filed: 1949-06-21
Abstract: A hard metal alloy, particularly for tipping tools, consists of 25-75 per cent (preferably 35-60 per cent) TiC, 5-40 per cent VC, 5-25 per cent CbC, 1-20 per cent Mo2C, and 5-25 per cent (preferably 10-15 per cent) of metals of the iron group.  The TiC may be replaced wholly or partly by ZrC or HfC and additionally one or more from the group WC, CrC or TaC up to a total of 20 per cent may be added.  When producing the alloy the carbides may be added individually or in the form of mixed crystals of all or several of the carbides, in the latter case the remaining carbides being added individually.  In one product where all the carbides are pre-alloyed, a mixed crystal of TiC and Mo2C is formed at 1700-2000 DEG C. and the remaining carbides added forming a final mixed crystal at 1300-1500 DEG C.  To facilitate the formation of mixed crystals, 0.1 to 2 per cent of the iron group metals is added.
