Patent GB-847564-A (GB)
Title: A method of preparing unsaturated aldehydes from olefins
Filed: 1958-10-27
Abstract: Unsaturated aldehydes containing at least 3 carbon atoms are prepared by oxidising olefines containing at least 3 carbon atoms in the gaseous phase by bringing a mixture of oxygen and the olefine, the maximum oxygen concentration being 35% by volume, under superatmospheric pressures and at high temperatures, into contact with a copper surface, a thermostatic fluid being circulated around the surface, but not in contact with the reactants.  The thermostatic fluid is defined as a fluid of the type customarily used in heat exchange apparatus to remove heat from bodies at elevated temperatures.  Suitable thermostatic p  fluids are, for example, various fractions of mineral oil or a eutectic mixture of phenyl ether and diphenyl.  It is preferred to carry out the process in a copper tube having an internal diameter of 3 mm.  The preferred temperature range for the process is 200 DEG -600 DEG C. and the pressure range 1-40 atm.  The oxidation may be carried out in the presence of diluents.  In the examples propylene and isobutene are oxidised to acrolein and methacrolein respectively.  Among the by-products are saturated aldehydes, including formaldehyde, and acetone.  Specification 640,383 is referred to.

Title: Improvements in and relating to flexible tubes and packing
IPC: C08J5/00
Filed: 1933-12-06
Abstract: 429,766. Flexible tubes. SCHNABEL, E., 4, Zimmerstrasse, Lichterfelde, Berlin. Dec. 6, 1933, No. 34332. Convention date, Dec. 30, 1932. [Class 99 (ii)] [See also Group XXVI] Flexible tubes &c., with relatively stiff self-supporting walls for use in conveying organic solvents, dilute acids, &c., are made by working up into tubular form polyvinyl derivatives, e.g. polyvinylalcohol, either alone or together with other substances. The tubes may be formed by extrusion or by dipping, glycerine or like softening agents or filling material such as asbestos preferably being added to the polyvinyl alcohol, and a fabric covering may be applied to the tubes before setting. Alternatively the tubes are hardened by treatment with formalin or by the application of heat, then covered with an impregnated fabric, and finally reinforced by braided wire &c. Tubes may also be formed from woven fabric &c., which has been impregnated with the polyvinyl derivative, or from ordinary hoses by applying thereto a layer of the derivative on fabric or by working the derivative into the material of the hose. Tubes made as described may be covered with rubber or a rubber tube which is itself covered with the derivative, a mixture of latex and the derivative being injected between the various layers and the completed tubes finally vulcanized. The invention is also applicable to the manufacture of packing sleeves and washers. Specification 386,161, [Group IV], is referred to.

Title: A tube coupling
IPC: F16L19/10
Filed: 1954-11-26
Abstract: 762,447. Pipe couplings. WOODLING, G. V. Nov. 26, 1954, No. 34363/54. Class 99(1) The invention relates to pipe couplings which embody a sleeve 13, Fig. 3, adapted to bite into a pipe 10, the sleeve 13 having rearwardly extending segmental fingers 26, and a deflectible continuous front portion 25 which incorporates an annular rib 30, Fig. 2, of conical section connected by a longitudinal wall 35 to a lateral wall 41 terminating in an edge 43. The sleeve is also formed with a forward piercing edge 61, a tapered cam shoulder 36, Fig. 1, principal and auxiliary cam surfaces 40 and 58 and a complementary wall 59, Fig. 2. As the sleeve 13 is pressed forward into the body 11, upon tightening the nut 12, the cam surface 40, 58 contacts a first tapered part 17 of the body bore and inwardly deflects the leading portion 28 of the sleeve whereby the rib 30 and edge 43 bite into the tube 10 so that the sleeve and tube are advanced as one into the body 11; when the walls 35 and 59 engage the tube they limit the degree to which the rib and edge bite thereinto. As resistance to the axial movement of the sleeve is encountered a shoulder 37 in the nut engages the cam shoulder 36 and contracts the fingers 26 around the tube to support it against vibration. The nose 57 of the sleeve prevents shearing of the tube material in advance of the rib 30. The tube is in sealing engagement with the sleeve and a second tapered part 18 of the body 11 bore, and the inner sleeve wall 38 to the rear of the edge 43 is cammed into sealing engagement with the tube. In a modification, the edge is replaced by an other conical cutting-rib. In both of the foregoing embodiments the extreme forward part of the nose may also be formed with a conical cutting-rib.

Title: Method of testing the continuity of electrical conductors
IPC: G01R31/02
Filed: 1972-07-24
Abstract: 1366042 Testing conductors for continuity INTERNATIONAL BUSINESS MACHINES CORP 24 July 1972 [28 July 1971 18 Feb 1972] 34471/72 Heading G1U A method of testing a conductor 1, Fig. 1, for continuity includes the step of directing beams of electrons via apertures 4, 5 on to the ends of the conductor in such a way that secondary electrons are emitted by the conductor. As described the electron beams pass via a mask comprising a conductive layer 6, an insulating layer 7, and two further conducting layers 9, 10 insulated from each other, which surround the regions adjacent the ends of the conductors. If a small potential difference is maintained between the conducting layers 9, 10 which are referred to as collectors since they receive the secondary electrons from the conductor ends, and the conductive layer 6 is maintained about 100v negative of the collectors then it can be shown firstly that the current Ic that flows in the collector circuit can be expressed in the  form - where Ipr is the incident electron beam current, I is the conductor current and α is a constant, and secondly that the current I in the conductor will be substantially independent of the conductor resistance R providing R is less than a critical value of about 10 k# or substantially zero if R is larger than 10 k#. Then by applying a small alternating potential between the two collectors 9, 10, rather than a static potential difference, the current I, which will then also be alternating, can be determined by measuring the A. C. component of the collector current Ic. Alternatively, I can be determined by modulating the incident beam current Ipr. Having determined whether I is substantially zero or not, it immediately follows whether the conductor resistance R is above or below the critical value. In a practical embodiment which permits the incident electron beams to be focused from a single gun over a sufficiently large area and yet only have an energy of about 100ev, the apertures in the mask are inclined, as shown at 4A, 5A, Fig. 4, so that incident electron beams of energy about 20kev, strike the side walls of the apertures to produce secondary electrons which are given an energy of the required low level by maintaining about 400v across the mask, and these secondary electrons form the primary electrons that are incident on the ends of the conductor under test. Multi-layer masks, (such as in) Fig. 5 (not shown) may also be used.
