Title: Dihydroxy aluminium alkali metal or ammonium carbonates
IPC: C01F7/782
Filed: 1954-01-18
Abstract: Dihydroxy aluminium alkali metal (including ammonium) carbonates of general formula (OH)2AlOCO2X where X is alkali metal or ammonium are prepared by reacting an aluminium alcoholate of a C2-C4 alcohol with an aqueous solution of a bicarbonate in the proportion of at least 1 mole of bicarbonate per mole of alcoholate to obtain a precipitate which is separated from the aqueous mixture.  Examples relate to the production of sodium, potassium and ammonium containing compounds of the above formula prepared by adding aluminium isopropylate, preferably as a thin stream, to vigorously stirred solutions of the corresponding bicarbonate in equi-molecular amounts.  A gelatinous product was precipitated which on stirring became granular and was subsequently filtered.  The precipitate may be air dried for several days then oven dried to a moisture content of 15 per cent at 55 DEG C.  Other alcoholates specified are the ethylate and tertiary butylate.ALSO:An antacid compound for the relief of excess gastric acidity comprises a dihydroxy aluminium alkali metal (including ammonium) carbonate of general formula (OH)2 Al OCO2X where X is alkali metal or ammonium (see Group III).  The compounds may be employed in tablet or equivalent form.  The acid consuming power of the compound is compared with that of sodium aluminium carbonate and a mixture of aluminium hydroxide and sodium bicarbonate.

Title: Apparatus for the removal or discharge of electrostatic charges from the surfaces ofmaterials of poor electrical conductivity
IPC: H05F3/04
Filed: 1952-01-18
Abstract: 707,933. Discharging static electricity; condenser arangements. SOC. FINANCIERE D'EXPANSION COMMERCIALE ET INDUSTRIELLE SOC. ANON. SFINDEX. Jan. 18, 1952 [Jan. 20, 1951], No. 1543/52. Classes 35 and 38(4) An electrode for discharging static electricity from fabrics &c. of low conductivity is energized from an H.T. transformer whose primary winding is fed by the discharge of a condenser which is alternately charged from an A.C. supply and discharged through the transformer by means of a suitably phased synchronous vibrator. As shown in its simplest form, Fig. 2, the vibratory switch 12 is fed from a transformer 16 energized from the A.C. mains 15 so that the condenser 2 is alternately charged at contact K2 with a potential U2+U1, and discharged at contact K1 through the primary winding of transformer 1 so that a high voltage impulse appears at the terminal 7. Diagrams are given to show how the natural oscillation of the spring armature 3 under the influence of coil 13 produces correct timing of the contacts. A modification is described for providing a more continuous excitation of the H.T. transformer, comprising a pair of vibrator circuits connected in push-pull and arranged to receive energizing currents with 90 degrees phase displacement. Two H.T. transformers with series-connected primary windings may be used to supply two electrodes. A strip of fabric 11 may be discharged by passing over an electrode as shown in Fig. 9, comprising an insulating rod 22 grooved at 23 to receive a fine wire 24 connected to the H.T. transformer. Several such grooves may be used and may be covered over with a fine-mesh, non-conducting fabric to reduce the danger of fire. In a modification, Fig. 11, the insulating rod may be axially split to receive a metal foil 25 whose edges provide the necessary glow discharge, and in a further modification the rod is divided into three sectors separated by foil. The web may zig-zag between several bars so that both sides are discharged. The H.T. transformer may be fitted inside the insulating rod which is suitably hollowed out. The discharge electrode may comprise a loop or coil through which a bundle of fibres or a stream of granular material is passed. Alternatively, the tubular electrode may be divided into a series of insulating discs separated by discs of conducting foil joined at their outer edges by a metal ring connected to the supply. The electrode may consist of a conducting tube surrounded by an insulating sheath prevent direct contact with the web, the discharge taking place by capacity only.

Title: Apparatus for feeding elongated articles

IPC: B23B13/00
Filed: 1964-01-14
Abstract: 1,024,797. Metal strip feeds. BROOKES (OLDBURY) Ltd. Feb. 11, 1965 [Jan. 14, 1964], No. 1543/64. Heading B3W. An apparatus for feeding bars or tubes to a dividing apparatus comprises a pusher 12 arranged to engage the trailing end of the work (not shown), a chain 13 for driving the pusher, a sensing element 16 movable between an inoperative position and an operative position in which it is engaged with the chain to move therewith, the movement to the operative position being effected by an air cylinder 19 controlled by a stop 28, and means engageable by the sensing element when moving with the chain for effecting ejection of the trailing end portion of the preceding workpiece from the dividing machine. Operation.-Work is lifted into the feed trough by arms 26b, which are actuated by a cylinder 26, and is moved by the pusher 12 towards (left to right in Fig. 1) a dividing machine which has a gripping device which holds the work while it is being cut, and feed rolls for advancing the work through the machine. When the trailing end of the work passes a pivoted flap 24, the flap falls and operates a valve 25 to energize the cylinder 26, and also a cylinder 27 which lowers the stop 28. The cylinder 27 is pivoted at 29, so that when the leading end of a new workpiece engages the stop it swings forward and operates a valve 30, which energizes the cylinder 19, lowers the sensing element 16 into engagement with the chain 13, and raises the stop 28 from the path of the workpiece. A pneumatic valve 21 which is engaged by the element 16 is positioned at such a distance from the dividing machine that when the remaining length of workpiece is too short to be safely gripped by the gripping device of the dividing machine, the valve is operated and varies the cycle of the dividing machine so that the gripping device does not close and the short end is ejected by the leading end of the new workpiece. A further pneumatic valve 22, restores the cycle of operation of the dividing machine and reverses an air motor 14 driving the chain 13. During its reverse travel the element 16 engages a pneumatic valve 23 which energizes the cylinder 19 to lift the element to its inoperative position, and the pusher 12 continues to move to the left-hand end of the apparatus to a position in which it is ready to engage the trailing end of a new workpiece.

Preferably the resilient means comprises a coiled end portion of the elongate member 6 which absorbs the overtravel thereof. Arm 10 is secured in a slot (9, Fig. 4, not shown) in shaft 2 together with a terminal strip 11 and has slight resilience to provide a wiping action of contact 12 over fixed contact 13. The member 6 is secured to seat portion 8 by means of a slidably adjustable member 7. The shaft 2 has a radial lug (3, Fig. 4, not shown) at one end for co-operation with a recess (4) in housing 1 to limit its angular displacement.

A strip 1 is fed into a slotted sleeve 2 to form a tube 3 and the helical seam thereof is welded by a head 4, welding from the outside, and a head 6, first welding from the inside. A roller 13 which engages the edge of the strip within the sleeve is connected to the head 4 which is swingable on an arm 5-about a vertical axis and a roller 12 engaging the edge of the strip in advance of the roller 13 is connected to the head 6. The device for gauging the width of the welding gap between the edges of the strip comprises a pair of feelers 15, 16 which engage the strip edges, one feeler moving the carrier of a dial gauge 17, the other engaging the measuring-pin of the gauge. The gauge indicates the gap width and by a device 18 the reading is transmitted to a motor which through gearing moves jaws 8, 9 through which the tube slides to shift the tube transversely to correct the gap width.

A filter 18 prevents the tones reaching the exchange. The trains are verified in a detector 14 individual to the extension line involved. The detector transmits the line identity to monitoring unit 5 where it is printed or logged for billing.
