Title: Improvements in or relating to artificial resinous materials and to the preparation thereof
IPC: C08F236/04
Filed: 1946-03-20
Abstract: Resins are prepared either by heating a drying oil or drying oil fatty acid and dicyclopentadiene in a closed vessel at a temperature of at least 200 DEG C. until a copolymer soluble in hydrocarbon thinners is obtained or by heating a drying oil or acid therefrom with cyclopentadiene or cyclohexadiene at a temperature from 30 DEG to 120 DEG  C. in the presence of a polymerization catalyst till a similar copolymer is obtained. Oils specified are soya bean, linseed, perilla, chinawood, oiticica, cottonseed, corn, fish and tung oils, and acids named are those from linseed and soya bean oils.  Catalysts specified are stannic chloride, dihydroxyfluoroboric acid and boron fluoride-ethyl ether complex.  Xylol may be used as solvent in the reaction.  The resin may be isolated by adding alcohol or acetone and filtering, or evaporating the solvent if used.  Addition of ammonia or an amino-compound inactivates the catalyst. Hydrocarbon thinners, pigments such as titanium dioxide, calcium oxide, antimony oxide, carbon black, aluminium, zinc paints, lithophone, indene resins and asphaltum may be added to the copolymer.  A mixture of cyclopentadiene, drying oil or fatty acid therefrom and a catalyst may be heated in an apparatus of which three forms are described.  In one form, a column is used with an upper and lower jacket at different temperatures, while in another form two separate reaction vessels are connected, a partial polymerization being effected in the first vessel.  If desired, the product from the second vessel may be recycled to the first vessel.

Title: Automatic telecommunication switching system
IPC: H04M3/22
Filed: 1973-02-22
Abstract: 1412876 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 22 Feb 1973 [25 Feb 1972] 8633/73 Heading H4K A telecommunication system controlled by a duplicate processor includes means to withdraw either processor from service and to use that processor to test newly added switching equipment. As described the system is generally similar to that described in Specifications 1,181,182 and 1,181,184 but the control unit includes a teletypewriter unit via which a special instruction can be entered and a punched tape unit on which is stored the special program necessary for the withdrawal and testing. Withdrawal is effected in two stages in the first of which the processor is instructed by program modification not to accept now calls and to test for calls being processed but not yet established. When all calls have been established or a time out operates (whichever is the earlier) the processor withdraws from service after a check on the condition of the other processor to ensure that it is ready to take over complete control. The figure shows a section of a sectionalized switching network in which there is only one path between each subscriber line circuit LIC and each originating or terminating junctor OJC or TJC. The use of a network of this type enables the path elements used to be uniquely identified by the identities of the line circuits and junctors to be employed and various tests on the path elements, e.g. by testing all paths through a given element, and D.C. and A.C. line continuity tests on the subscriber loops and junctor circuits are described.

Abstract: 351,043. Printers' composing- machines. UHERTYPE AKT. - GES., Kubli House, Poststrasse, Glarus, Switzerland. March 18, 1930, No. 8745. Convention date, March 18, 1929. [Class 100 (iii).] Justifying type.-Line justifying in photographic type-composing is effected by two slides one of which takes up the fraction of the movement of the other corresponding to the line remainder divided by the number of word spaces in the line. The slide 3 is stepped for the line remainder by two magnets alternately ener. gized, one of which reciprocates during the typesetting. At the end of the line the slide 19 is pressed by a compressed air cylinder against the end of the slide 3, a stop 28 on the slide 19, bearing on a roller 27 on a transverse lever pivoted on a slide 29, the lever also bearing on a roller 26 on a second slide 20 parallel to the slide 19. The ratio of transmission from slide 19 to slide 20 is derived from a stepped cam 32 advanced by ratchet mechanism at each depression of the " word space key " of the apparatus. The operation of slides 19, 29 is effected by compressed air cylinders actuated by cams 55 rotated by a worm 48 when the clutch element 46<1> is engaged with the clutch element 46 on a continuously rotated shaft by operation of the electromagnet 50. A single tooth clutch element 47, 471 limits the rotation to a single revolution.

Title: Improvements in or relating to methods of and apparatus for forming rubber threads or the like
Filed: 1935-03-20
Abstract: 443,809. Malking rubber threads. GAMMETER, J. R., 680, Portage Path, Akron, Ohio, U.S.A. March 20, 1935, No. 8748. [Class 70] Rubber threads are made by separating a continuously moving strip of rubber into threads by the progressive application of localized heat and pressure. A metal belt 19 carries two strips 20 (produced by deposition or other methods) between two hollow rotating mandrels 17, 18 where they are cut into threads by annular spaced knives 48 carried by the mandrels. The mandrels may be heated by steam, electricity, or, as shown, by gas from the interior. A temperature of 200 to 300‹ F. and a pressure of 2¥ to 3 pounds per knife is usually sufficient. The belt 19 and the mandrels have a common drive, and the belt speed equals the peripheral speed of the knives. To prevent sticking together of the threads the strips or threads may be dusted with talc, or coagulant may be applied to the strips by rollers 61. For the same purpose and to prevent sticking between the knives and ensure sticking to the belt, endless wires 96, 104 travel with the belt and pass between the knives. The ends of the mandrels are supported by straps in frames 24, 66, and rotate in contact with ball-bearing rollers 25. The positions of the frames 24, 66 are adjustable, e.g. frame 66 66 may be pushed toward frame 24 by a poweroperated piston 84 acting on a rod 75 pivoted at 81. The mandrels are cleaned by metal brushes 33.
