BOC - Pro - Ser - Lys(BOC)NHNH2 is prepared through BOC-Pro-Ser-OMe and its hydrazide and BOC - Pro - Ser - Lys(BOC)OMe. (BOC = tertiary-butoxycarbonyl; CBO = carbobenzyloxy; Tri = trityl and NP = p-nitrophenyl.)  Pharmaceutical compositions comprise the nonapeptide and its salts in conjunction with a pharmaceutically acceptable carrier.  The compositions, which may be in a form suitable for parenteral administration or in the form of a depot preparation, show anti - hypertensive action.

In a first embodiment of such a device, Fig. 4, compressed air fed from tube 10 passes through an annular space 15 between a top part 14 and a nozzle body 13, and is directed downwardly through an annulus 16 into the nozzle body, producing a vacuum at an opening 17 over which the sheets are advanced. In an alternative embodiment Fig. 5, the compressed air flows radially from an annular space 21 into a nozzle body 18 and follows its curved surface downwardly into a hose 23 producing a vacuum at 22. The suction openings are covered with discs having slots extending perpendicularly to the sheet travel direction. Magnetic valves may be used to control compressed air-flow.

Abstract: 1,188,966. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 17 Sept., 1968 [24 Oct., 1967], No. 48235/67. Heading H1K. A circuit sub-assembly is constructed by forming at least one slot in a plate of electrically and thermally conductive material so as to define two or more plate portions connected by web portions, mounting semiconductor elements on at least one of the plate portions, providing electrical connections between the elements and selected plate portions, encapsulating the elements and connections while leaving the webs exposed and severing the web portions. The elements may be planar diodes or one-way thyristors. A sub-assembly comprising a bridge circuit with a thyristor across the D.C. output of the bridge (Fig. 1, not shown), is constructed as shown in Fig. 2. A copper plate 10 has slots 8 and 9 formed therein giving strips 1 to 7, diodes A, B, C and D and thyristor E are mounted on the plate using lead-tin solder and connected with aluminium wire to give the sub-assembly. The assembly is placed in a mould and encapsulated with plastics material leaving ends of the strips 1 to 7 and the webs joining them projecting from the encapsulation. The webs are then severed (Fig. 3, not shown). Alternatively the connections E,4 and 3, 5 may be made externally subsequent to encapsulation. In another embodiment (Figs. 4 to 6, not shown), a subassembly comprising two diodes in inverse parallel with two thyristors having a common cathode connection is formed. The area of copper for each thyristor must be adequate to allow for heat dissipation. Reference has been directed by the Comptroller to Specification 1,112,604.

Abstract: 1,093,277. Valve-discharge water-waste-preventers. SHIRES & CO. (LONDON) Ltd. Dec. 7, 1964 [Dec. 6, 1963], No. 48338/63. Heading EIC. In an air pressure W.C. flushing system a large bore flush pipe 16 with a valve 17 therein leads to the pan and is connected to the water supply and to the bottom of a primary air chamber 10, connected at the top thereof to the bottom of a secondary chamber 11 through a restricted passage 15. The volumes of the chambers 10, 11 are so related that at the minimum supply pressure all the air therein will be compressed into the chamber 11, a quantity of water following it. There is an ejector or venturi device 18 where the supply pipe 20 enters the flushing pipe, the flow therefrom inducing a sub-atmospheric pressure in the chambers 10, 11 while the valve 17 is open. Automatic timing means holds the valve 17 open long enough for flushing to occur and keeps it open for a delay period period after the air has ceased to expand and driven water out of the chamber 10. Timing means prevents the valve 17 opening again within a predetermined period after closure. In a modification the air chambers are below the pan top within a pedestal. Instead of being in the same tank the secondary air chamber is separate from the other and is formed as two vessels below it, one on each side, the flush pipe and valve being therebetween, and also the venturi, which is on the mains side of the valve. The secondary chamber may have a valve to allow air entry when flushing is complete and before the valve 17 closes.
