Title: Improvements in and relating to apparatus for reproducing, recording or amplifying sound
IPC: H04R9/04
Filed: 1928-08-03
Abstract: 319,455. Watson, T., and Owen, R. E. L. Aug. 3, 1928. Loud-speakers; magnetic instruments; diaphragms.-In sound reproducing and recording apparatus, of the moving coil type., a rigid diaphragm is flexibly mounted, so that the diaphragm and coil balance one another about the plane of suspension. A conical diaphragm e has a cone f with a re-entrant portion g, carrying a sleeve h on which the coil d is wound, or the coil d may be carried by the outer cone e. A further strengthening cone may be fitted between the cones e, g. The diaphragm e is mounted by a flexible annulus i reinforced by radial or tangential phosphor bronze strips which may be utilized as leads to the moving coil d, so that diaphragm and coil balance about the plane of the annulus i. Apertures k, k<1> in the pole pieces permit free movement of air and prevent air damping, while the pole pieces are built up in sections to assist this effect and to produce magnetic saturation. The diaphragm may be of hemispherical shape, when the central pole piece should be mushroomheaded. Specification 302,199, [Class 13, Bells &c.], is referred to.

Title: Improvements in the production of dyestuffs of the anthraquinone series
IPC: C09B1/22
Filed: 1948-08-27
Abstract: A mixture of 1.5- and 1.8-di-(acidylamino)-anthraquinones is dinitrated in presence of boric acid in sufficient concentrated sulphuric acid to maintain the nitration product in solution. About 2 1/2 -5 per cent of boric acid based on the weight of sulphuric may be used, and the nitration temperature may be 0-5 DEG  C.  The dinitro-diacidylamino-anthraquinone may be reduced with sodium sulphide to a diamino-diacidylamino-anthraquinone, which may be hydrolysed to 1.4.5.8-tetraminoanthraquinone.  As some hydroxy bodies may be formed during the nitration and may be present as impurities in the 1.4.5.8-tetraminoanthraquinone, affecting the shade given by it on cellulose derivatives, the final product may be methylated, and the methylation and hydrolysis may be combined by heating the diamino-diacidylamino-anthraquinone with sulphuric acid and methyl alcohol.  An example describes the diacetylation of a mixture of 1.5- and 1.8-diaminoanthraquinones, the di-nitration of the product in presence of boric acid, followed by reduction with sodium sulphide of the nitro groups, and combined hydrolysis and methylation with sulphuric acid and methyl alcohol.

Patent GB-923652-A (GB)
Title: Process for separating triethyl aluminium from other ethyl metal compounds
IPC: C07F5/06
Filed: 1960-06-28
Abstract: Triethyl aluminium is separated from mixtures with ethyl compounds of metals of the second to the fifth group of the Periodic System by converting it into an alkali metal cyanide complex which separates out as a separate phase, isolating the ethyl metal compound not combined in complex form and if necessary splitting off free triethyl aluminium from the triethyl aluminium-cyanide complex.  In particular the process is applicable to separation from tetraethyl lead, but it may be used in separations from ethyl compounds of zinc, cadmium, mercury, indium, gallium, thallium, antimony and bismuth.  It is preferred to form the 1:2-alkali metal cyanide:triethyl aluminium complexes, and in so doing either alkali metal cyanide or the 1:1 cyanide comple may be used.  The mixture containing the complex should be cooled as much as possible before separating the phases in order to achieve the lowest possible solubility of the uncomplexed ethyl metal compound in the triethyl aluminium complex.  In the case of tetraethyl lead, its solubility in the complex can be further reduced by adding from 5 to 20% of the fluoride complex NaF.2Al(C2H5)3.  The complex may be converted to the alkali metal tetraethyl aluminium complex, which process converts any tetraethyl lead present to lead, or it may be thermally cracked to give triethyl aluminium.  Specifications 779,874, 814,609, 848,364 and 923,651 are referred to.

Title: Corrugation-forming machines
IPC: B21D31/00
Filed: 1972-05-16
Abstract: 1420952 Corrugation-forming machine COVRAD Ltd 9 May 1973 [16 May 1972] 22853/72 Heading B3E [Also in Division F2] A corrugation forming machine comprises two rotatable die rolls 10, 11 having intermeshing teeth 14 between which material 15 to be corrugated is passed, a drive for rotating the rolls, and an oscillating device arranged to cause the relative angular velocity of the die rolls to change during their rotation. The rolls 10, 11 may be spring-loaded towards one another, and a sinusoidal oscillation is imparted to one or both of the rolls about their axes of rotation so that at any one time the or each oscillated die roll rotates at a speed faster, slower or equal to the mean angular velocity. Rolls 10, 11 are interconnected by meshing equal-ratio spur gears 21, 22, Fig. 2, connected to the rolls by shafts 23-28 and universal joints 29-32. Shaft 27 is carried in bearings in a framework including plates 33, 34 pivoted about the axis of shaft 28. Gear 21 is connected through step-up gears 37-40 to an eccentric 41. The assembly is driven by an electric motor connected to one of the shafts 24, 36, 42 or 43. Upon rotation of roll 10 eccentric 41 is caused to rotate and in turn causes rod 44 to oscillate and the plates 33, 34 to rock in a sinusoidal manner about shaft 28. Gear 21 rolls back and forth around gear 22 to impose a sinusoidal torsional oscillation on the steady speed of the latter. A corresponding angular velocity pattern is transmitted to roll 11 via shafts 23, 25, 27 and joints 29, 31. A lobed cam may be used instead of a simple eccentric having a step-up ratio from shaft 36 to shaft 43 equal to the number of teeth on each roll. In an alternative embodiment, Fig. 3 (not shown), gear-wheels (45), (46) are driven by worm-wheels (47), (48). An electric motor (62) drives the wheels (47), (48) through Hooke's joints (55)-(58) and intermediate telescopic splined shafts 59, 60. The teeth 14 of each roll may be provided with louvre-cutting devices 65, Fig. 4, formed on the flanks 20 and which are each formed as inserts in the teeth. Projections 66 of the devices form corresponding slits and depressions in the aluminium foil strip 15. The die rolls 10, 11 are made up of thin discs, which are assembled using through-bolts to form a laminated roll (67), Fig. 6 (not shown). The teeth 14 of the rolls may have different forms, e.g. the tips 18 and roots 19 may each consist of points, Fig. 7 (not shown), flats, or slightly convex portions.

Title: Improvements in or relating to voltage stabilisers and protection arrangements therefor
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: G05F1/32
Filed: 1966-05-23
Abstract: 1,116,764. Protective systems. GENERAL ELECTRIC CO., Ltd. 23 May, 1967 [23 May, 1966], No. 22877/66. Heading H2K. In a protective arrangement for a voltage stabilizer of the kind comprising a saturated reactor SR connected in series with a capacitor CS across an A.C. supply system, a saturating reactor ST which is unsaturated during normal working is shunted across the capacitor. The reactor ST saturates to limit the voltage across the capacitor and to cause the operation of safety means when excess currents or instabilities occur. As shown the reactor ST is a transformer having its secondary winding S connected through a rectifier DV to a control winding W1 of a transductor TR. A current transformer CT in series with the capacitor supplies a second control winding W2 of the transductor TR. The control windings act in opposition and normally balance each other. Any condition which disturbs the balance between these windings causes the impedance of the main transductor winding M to fall so that the trip means DT of a circuit-breaker CB can function after a delay. In an alternative arrangement, the capacitor may comprise two parallel sections and the current through one section is balanced against the current through the other section and the reactor ST. Fuses may be associated with the capacitor CS and a spark gap SG of the permanently short circuiting type may be connected across the capacitor. In a modified arrangement, Fig. 2 (not shown), relays are provided to prevent incorrect operation under transient conditions and to by-pass the capacitor CS under such conditions.

Filed: 1973-05-14
Abstract: 1414925 Packaging TECHNICON INSTRUMENTS CORP 14 May 1973 [7 June 1972] 22902/73 Heading B8C [Also in Divisions G1 and B1] Apparatus for forming successive discrete volumes of a liquid such as a sample-reagent mixture for analysis comprises elongated tubing 12 having spaced seals 30, (100) formed in it to provide separate chambers isolated from one another, drive means 18, 20 for moving the tubing along a path and supply means located along the path for supplying predetermined quantities of liquid through punctures into each chamber, the arrangement being such that each chamber is expanded while liquid is being supplied to it to draw the liquid through the puncture into the chamber. In the embodiment shown, each seal 30 is initially formed with L-shaped passages 36, 38. The sample and reagent containers 40, 72 are held in support collars mounted on flexible endless members 56, 86. Each container has a stopper carrying a hypodermic needle and a valved air inlet; when the base of each container is raised as it travels over cam 68 or 96, the needle punctures the tubing 12 as shown. The tubing and the containers travel together, the volume of the chamber V increasing as the tubing is drawn through rollers 18, 20 and first sample then reagent is drawn into the chamber as the valved air inlets are opened in turn. Valve 82 is then closed and the other air inlet valve (46) opened to allow flow of a predetermined volume of air into the tube. The needles are withdrawn when the containers reach the ends of the cams 68, 96, and the puncture openings in tubing 12 may be sealed. The apparatus may be used in the separation of lymphocytes from whole blood samples, when the tubing with its sealed chambers containing blood separating agent mixture is advanced over a helical drum through incubation means and made to travel vertically to allow sedimentation, each chamber then being subdivided by further seals each containing different blood components (Fig. 8, not shown). The apparatus may also be used in colorimetric analysis of blood samples (Fig. 10, not shown).

Title: Holder for a pack of cards
IPC: B42F7/14
Filed: 1965-06-01
Abstract: 1,095,238. Card holders. R. H. COOK. June 1, 1965 [June 1, 1964], No. 23280/65. Headings B6A and B6E. [Also in Division G5] A ease 20 containing a pack of resilient cards 45 has its inside faces contoured to enable the top card to be urged forward by a finger of an operator, and curved about the pack, to take up a position at the bottom of the pack. The cards may be thin sheets of metal, plastics material, or laminates of various materials having a high resilience and elastic limit. Cards of unplasticized copolymers of vinyl chloride and vinyl acetate may be calendered to a matt finish, and may have indicia thereon, Figs. 10 and 11 (not shown), on the top surfaces which reads in sequence as each card is exposed: the reverse sides of the cards may have indicia thereon which also reads in sequence when these sides are finally exposed in the pack. Alternatively, the cards may receive written messages, or written answers to questions printed thereon. The case 20 may be of wood, metal, or plastics material, and is shown as a moulding of polystyrene plastic resin comprising top and bottom portions 21, 22, which may be sealed together at the junction 23, or secured by latching means when the pack 45 of cards has been inserted. The portion 22 is apertured at 30, Figs. 1 to 5 (not shown), and has raised longitudinal ribs 31 which slope upwardly from the base near the end wall 28, slope downwardly at 31B and 33 to leave a recess beneath the front edge of the pack, and then slope upwardly at 31A to a point above the junction 23. The top 21 has a window 40 and complementary ribs 42 which are curved to match the ribs 31 at 31A. A stop lug 32 for all but the top cards of the pack is formed on a side wall 26 of the bottom portion 22. When the operator presses a finger &c. on the top card, or uses a slide device, and urges that card forward, the card is flexed around the curved surface formed by the rib portions 31A, 42, and moves in a bowed position along the ribs and beneath the pack, to take up a position at the bottom of the pack: this is achieved partly by the curvature of the ribs 31, 42, and partly by the resilience of the cards. When a card jams, the operator inserts a finger through the bottom aperture 30 to release it. For educational purposes, the window 40 in the top portion of the casing may have a smaller opening terminated at 48, Fig. 1 (not shown), so that the rear part of each card, which contains answers to questions on the front part of the card, is concealed.
