Filed: 1971-05-21
Abstract: 1306007 Polymerizing dienes SOLVAY & CIE 21 May 1971 [22 May 1970] 16381/71 Heading C3P Conjugated dienes are polymerized by means of a catalyst comprising (i) an insoluble macromolecular complex formed by reacting a compound of a metal of Group VIII with a di- or poly-functional ligand whose donor groups are so situated that they bond to different metal atoms, (ii) an organometallic compound, and (iii) optionally a small amount of water. Suitable complexes are obtained by reacting nickel or cobalt salts or chelate complexes in a suitable solvent with ligands having two or more groups selected from -NCO, -NCS, -CONR 2 , -O-, and nitrogen atoms in heterocyclic compounds, where R is hydrogen or an alkyl, cycloalkyl, aryl, alkaryl or aralkyl group, the functional groups being separated by at least 5 carbon atoms in the ease of acrylic compounds and by 2 to 6 carbon atoms in cyclic compounds. The polymerization of butadiene to a predominantly cis-1,4 polymer is exemplified, using complexes derived from CoCl 2  and hexamethylenetetramine, hexamethylenediamine, 1,4-dioxane or pyrazine which are activated by Et 2 AlCl. The use of soluble CoCl 2 - tetrahydrofuran or CoCl 2 -1,3-dioxan complexes is also described for comparison.

Title: Improvements in or relating to radio direction finding receivers
IPC: G01S1/02
Filed: 1938-06-02
Abstract: 494,408. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 2, 1938, No. 16596. Convention date, June 2, 1937. [Class 40 (v)] Relates to means for reducing the time required to take successive bearings on two or more beacon stations A, B, C, Fig. 1, each radiating different " impulse " frequencies on the same carrier wave. A " minimum " reading is first taken on beacon A, the direction being indicated on a cathode-ray tube Br as a trace formed by the " impulse " frequency and a local timing oscillation from a generator K. As soon as this has been found, a knob c on the time-base K is pressed fully onwards, and the frame aerial R swung into alignment with beacon C. The " impulse " frequency from C, which has meanwhile been present in the receiver circuits, now operates to control the position of the spring- controlled shaft of the knob C, Fig. 3, so as to change the tuning of the time-base K to cooperate with the new " impulse frequency. It does this by releasing a ratchet q at the proper point in the downward movement of the shaft which is geared to a condenser g. The latter, together with an auxiliary condenser Z1, controls the tuning of the time-base K.

Title: Improvements in tap outlet spouts
Inventor: KENT STANLEY GEORGE
IPC: E03C1/10
Filed: 1965-04-22
Abstract: 1,139,900. Valves. DENT & HELLYER Ltd. 22 April, 1966 [22 April, 1965], No. 16929/65. Heading F2V. A removable or fixed tap outlet 4 is provided with a skirt 5 around the discharge end 2 and a rod 3 between the latter and an upstream part of the outlet. If the rod does not pass through a slot 6 in the skirt the creation of a vacuum therein is prevented by an aperture 8. This arrangement reduces the risk of contamination since the rod 3 prevents a hose pipe being connected to the outlet or a vessel held adjacent thereto whilst the skirt precludes splashing of the outlet.

Title: Improvements in or relating to devices comprising an electric gas discharge tube
IPC: H05B41/232
Filed: 1946-06-04
Abstract: 612,787. Supply systems for space discharge apparatus. PHILIPS LAMPS, Ltd. June 4, 1946, No. 16939. Convention date, April 6, 1940. [Class 38 (iv)] The heating circuit of a discharge tube 1 includes, besides the normal ballast impedance 9 a double-wound choke 8, 13 with one winding on each side of a filament 2 and wound so that as far as the electrode heating circuit through the condenser 14 is concerned its impedance is a minimum. When, however, the electrodes are sufficiently heated and the tube starts, the winding 13 being shunted by the discharge carries less current than winding 8 and the choke has an effective impedance. A thinner gauge wire may be used for winding 8 than for winding 13 and the winding 8 may consist of a few strands of a stranded conductor, the major number of which serve for the winding 13. The condenser 14 and ballast 9 may be interchanged. A second double-wound choke may be associated with the other terminals of the tube. The invention is applicable to any tube comprising conducting bridges between terminals 4, 5 and 6, 7, whereby the circuit becomes interrupted when the tube is not in its holder; these bridges may be auxiliary discharge paths.

Title: Improvements in or relating to address-printing machines
IPC: B41L47/24
Filed: 1928-06-13
Abstract: 293,687. Adrema Maschinenbauges. July 9, 1927, [Convention date]. Feeding, winding, and registering webs. - A paper web is fed through an addressing-machine by a continuously-driven rewinding-device, which will allow the web to be cheeked so that addresses &c. may be printed at any desired positions on the web. As shown applied to a machine of the type comprising a printing-pad 4 carried by a rocking arm 2 driven from a motor 6 through a clutch 8 controlled by a pedal 9, a web 10 unwinding from a roll 14 passes over a printing-table 1 to a rewinding spindle 23 rotated by continuously-driven friction discs 30. In unwinding, the web passes under a heavy bar 18, which normally checks the advance of the web, and then under a gauge plate 16 adjustable in the direction of the web. After each impression, the web is pushed forward by hand to release it from the bar 18 until the rewinding-device feeds the web forward into position for the next impression, this position being indicated by the gauge 16. In place of the bar 18, the operator may use one hand to check the feed of the web. The unwinding and rewinding devices are in the form of attachments, the former comprising a plate 11<1> screwed to the table 1 and curved at 13 to form a guide and having also depending brackets 14<1> for supporting the web roll 14, and the latter comprising, in addition to the parts 23, 30, guide rollers 25, 26 and a tension roller 27 on the end of a plate spring 28. When the addressed web is to be rewound again, the roll is mounted in the brackets 14<1> and rewound on to the spindle 23, the bar 18 and rolLer 27 being dispensed with, and a braking-roller being mounted in brackets 38 to prevent too rapid rewinding.

Title: Improved manufacture of hydrogen peroxide
IPC: C01B15/032
Filed: 1938-06-09
Abstract: 507,121. Hydrogen peroxide. SEMIDEI, A. C. June 9, 1938, No. 17213. Convention date, June 9, 1937. [Class 1(ii)] In the production of hydrogen peroxide by reacting barium dioxide with phosphoric acid, the operation is carried out in two successive stages: the first stage at a low temperature during which hydrogen peroxide is formed and the second stage at a high temperature during which the precipitated barium phosphate is coagulated. This prevents the nascent hydrogen peroxide being decomposed by heat. The first stage may be carried out at 0-6‹ C., and the second at 60-70‹ C. Initially, an excess of phosphoric acid over the barium dioxide may be used and in this case several successive operations may be carried out, each operation comprising the two stages set forth above but a fresh quantity of barium dioxide being added between each operation until the whole of the initial phosphoric acid is utilized. Preferably, the time of heating should be reduced during the last operation.

Abstract: 595,527. Extensible tables. KANDYA, Ltd., and PULHAM, L. F. July 5, 1945, No. 17230. [Class 52(iii)] An extensible table top, primarily intended for a tea trolley, comprises two leaves 6, 7 which slide in grooves 4, 5 respectively in each top side rail 2 of the table. To extend the table top, the leaf 7 is withdrawn from the lower grooves 5 and inserted into the upper grooves 4, the two leaves 6, 7 then being pushed rearwardly. In the preferred form the ends of a pair of links 12 are pivotally attached to the two side edges of the leaf 6, each of the other ends being attached to the leaf 7 by a pin which engages in a slot 14 situated in the side of the leaf 7, the slots being closed at both ends, and after inserting the leaf 7 into the upper groove 4, the leaves are pushed rearwardly until the links 12 engage with abutments 20 in the grooves 4. On contracting the table top, withdrawal of the leaf 7 from the grooves 4 automatically moves the leaf 6 to a central position in relation to the supporting framework, pins 10 on the leaf 6 co-operating with pins 11 on a partition 8 to determine this central position, and the links 12 hold it in this position while the leaf 7 is pushed into the lower groove 5.
