[Also in Group XXXVII] A contact converter comprises, in series with a switching choke, electromagnetically operated switches having a sufficient number of breaking points in series so that should one gap be bridged, e.g. by particles detached from the contacts, the reverse voltage will not break down the remaining gaps. Control windings of each switch connected in series with a valve which is energized to initiate contact closing, may be connected in parallel with the switch contacts and the switching choke. The switches with their control and main windings may form separate structures or be combined as shown in Figs. 2 and 3. Two combined armatures and moving contacts 13 mounted on springs 21 co-operate with a common fixed contact on magnetic pole pieces 11 and separate contacts on mutually insulated pole pieces 12a, 12b. These polepieces carry terminals 19 and form the conductors to the contacts.

Novel 6-aminopenicillanic acid esters of the Formula (I) wherein X is the group-O-N = CHR where R is an alkyl, aryl or heterocyclic group, and acid addition salts thereof, are prepared by treating a corresponding acylaminopenicillanic ester of Formula (II) wherein R is an organic radical and X is as before, with an inorganic acid halide in an inert anhydrous organic solvent in the presence of a tertiary base to give a halogen derivative of Formula (III) wherein Y is halogen, adding a C 1 -C 6  alkanol to give a compound of Formula (IV) wherein R<SP>1</SP> is a C 1 -C 6  alkyl group, and hydrolysing to give the required ester. The solvent is preferably a chlorinated hydrocarbon, and the base and acid halide may be respectively N- methyl morpholine and phosphorus pentachloride. The hydrolysis is performed by adding water to the reaction mixture, when the ester remains in the organic solvent phase. It may be isolated by separating and drying the organic phase and adding an organic solvent solution of benzenesulphonic acid or toluenesulphonic acid to effect precipitation of the crystalline benzenesulphonate or toluenesulphonate salt of the ester. Reference has been directed by the Comptroller to Specification 1,122,306.

Title: Conduit system comprising a conduit section and method of detecting leaks in a conduit section
Inventor: EATON BURTON EMERY
IPC: G01M3/22
Filed: 1965-02-23
Abstract: 1,101,493. Testing for leakage in hollow articles. MIDWESCO-ENTERPRISE Inc. Feb.23, 1965, No.7838/65. Heading G1S. A conduit system has an inert pressurized low moisture content, heat insulating gas located in a sealed annular space 21 defined between one or more fluid conducting conduits 14 and a surrounding outer conduit 12, leakage into the annular space from the conduit or conduits or from the surrounding environment being detected by sensing a change in the pressure of the gas and means operative in response to a pressure loss for forcing pressurized fluid into the closed compartment at a pressure at least equal to the pressure of the environment to prevent leakage from the environment into the closed compartment. In the embodiment illustrated the conduit system comprises an outer protective conduit 12 disposed concentrically about an inner supply pipe conduit 14 which is insulated substantially along its entire length. The ends of the conduit 12 are closed by plates 26 to form a closed compartment between the inner and outer conduits. A safety relief valve 38 is provided in the bottom of the outer conduit 12 for relieving excess pressure. A control panel 46 is connected by a line 44 to the annular space 21, the control panel having valves to operate the supply of gas such as nitrogen into the space 21 and a pressure gauge 48 for measuring the pressure therein. Initially the gas is introduced into the space to a desired pressure such as 5 p.s.i. when the system is cold and left to allow for absorption of some of the gas before recharging back up to the desired pressure. Any change in pressure is then an indication of a leak in the system which can be shown by the signals 62. In a modified arrangement the annular space may be pressurized if a break in the outer conduit occurs to allow for continued operation of the system. Means are also provided for detecting the precise leak point in the outer conduit by passing a short half life radio-active isotope through the system which will leave the conduit at the break point to be detected by an instrument such as a geiger counter.
