Abstract: 1,174,425. Ethylene-propylene-decatriene terpolymers. COLUMBIAN CARBON CO. 8 Dec., 1966 [29 Dec., 1965], No. 55087/66. Heading C3P. A monomer mixture of ethylene, propylene and 1,4,9-decatriene, or a hydrocarbyl derivative thereof, is polymerized in the liquid phase with a co-ordination catalyst at a temperature of about 70‹ to about 130‹ F., the polymerization being conducted under a super-atmospheric pressure sufficient to maintain a substantial proportion of the propylene monomer in the liquid phase and a partial pressure of ethylene of at least about 8 p.s.i. The 1,4,9-decatriene derivative may be the 7-phenyl, 1-methyl, or 1-ethyl derivative. Specified catalysts are combinations of an aluminium compound, e.g. triisobutyl aluminium, diethyl aluminium chloride, monoethyl aluminium dichloride, ethyl aluminium sesquihalide, a mixture of diethyl and monoethyl aluminium chlorides or of triethyl aluminium and aluminium trichloride, with a vanadium compound, e.g. vanadium tetrachloride, diethyl chlorovanadate, monoethyl dichlorovanadate, vanadium oxytriacetylacetonate or vanadyl chloride. The catalyst is prepared beforehand or in situ. The polymerization may be carried out in an inert organic medium, e.g. a hydrocarbon or CCl 4  medium. In the examples, terpolymers of ethylene, propylene and 1,4,9-hexatriene are produced in solution in n-hexane, using as catalyst a mixture of ethyl aluminium sesquichloride and vanadyl chloride or of diethylaluminium chloride and diethyl chlorovanadate. Reference has been directed by the Comptroller to Specification 1,031,254.

Title: Improvements in or relating to switching circuits

Abstract: 1,240,110. Shift registers. PLESSEY CO. Ltd. 12 Dec., 1968 [14 Dec., 1967], No. 56940/67. Heading G4C. [Also in Division H3] In a shift register each one of a chain (Fig. 3, not shown) of clocked master-slave bi-stables has cross-coupled IGFET's 3, 4, Fig. 1a, forming the master flip-flop, coupled by means such as IGFET's 9, 10 to cross-coupled IGFET's 5, 6 forming the slave flip-flop, each transistor having a load L1 to L4 and a clock pulse C being applied to the master. The loads L1 to L4 are IGFET's having their gates and drains connected to the supply earth. The clock pulse is applied to the gate electrodes of gating IGFET's 1, 2 which are respectively connected in parallel with further input gates 7, 7a and 8, 8a. The positive clock pulse renders 1 and 2 non-conducting, and one or other of master IGFET's 3, 4 is turned OFF according to whether the inputs 7, 7a are both positive or whether the inputs 8, 8a are both positive. If all gating inputs 7, 7a, 8, 8a are positive the resultant state of the master flip-flop is indeterminate and if all are zero the state is unchanged. If, for example, the master flip-flop has been set by the inputs so that IGFET 3 is ON, and 4 is OFF, the coupling IGFET 9 cannot conduct due to the positive potential at its gate, but the coupling IGFET 10 will conduct when the end of the clock pulse allows the gating IGFET 2 to conduct again. Consequently, the drain of slave flip-flop IGFET 5 goes positive and turns OFF IGFET 6, so changing the state of the slave flip -flop according to the state of the master. The outputs X, Y of the slave may be connected to the gate inputs A1, B1 (Fig. 2, not shown), so that the complete master slave arrangement acts as a J-K flip-flop responsive to J, K inputs at A, B. Set and Reset inputs may be applied to further input IGPET's C1, P1, C2, P2.
