Patent GB-1300078-A (GB)
Title: Frequency divider circuit system
Inventor: YOSHINO HIROKAZU
IPC: G06F7/68
Filed: 1969-12-19
Abstract: 1300078 Frequency divider MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Dec 1969 62134/69 Headings G4D D7X D6Y D6C1 and D6C2 A frequency divider includes a delay circuit T, a counter consisting of several cascaded flip-flops F o -F n , and an AND gate G for producing the logical product of the flip-flop outputs and the undelayed input pulses, the output of the AND gate being selectively applied to the inputs of the flip-flops. The arrangement ensures that feedback pulses to the flip-flop always precede the corresponding input pulse applied to the counter by a time equal to the delay T and malfunctions due to coincident pulses at flip-flop inputs are prevented. As described flip-flops F 1 -F 3  are provided with input gates G 1 -G 3  so that the counter can be set initially to a count of 15. Succeeding input pulses set stages F 4 -F n  before gate G produces an output which, via selected ones of gates R o -R n-1  resets the counter. The frequency of the output is controlled by the circuit H which enables selected ones of the gates R. In a modification, Fig. 6 (not shown), the counter is divided into stages each of four cascaded flip-flops, each stage representing a decimal digit. High speed decimal carry between stages is achieved by means of a gating arrangement. The outputs of flip-flops (F 0 ) and (F 3 ) in each stage are coupled to an AND gate whose output sets the first flip-flop (F 4 ) in the next stage. The inputs to flip-flop F 1  in each stage is derived from an AND gate whose inputs are the output of F 0  and the complementary output of F 3 . Flip-flop F3 has a complementary input fed from an AND gate whose inputs are the output of Fo and the true output of F 3 .

Patent GB-799838-A (GB)
Abstract: 799,838. Sparking plugs. GENERAL MOTORS CORPORATION. July 5, 1956 [July 8,1955], No. 20847/56. Class 7(4) The centre electrode is used as a hot press ram for forming a seal in the plug insulator bore between the insulator, electrically conductive seal material in the bore, a terminal within one end of the bore, and the centre electrode within the other end of the bore, and for bringing the centre electrode into abutment with semiconductor material at the other end of the bore. As shown, a sparking plug comprises a glass like conductive seal 43 for example a mixture of glass and copper or nickel powder and a semi-conductive member 13. Semi-conduc-tor materials found to be most suitable are the stanno-titanate compositions though silicon carbide, germanium, various sulfides and sub-conductor material as copper or nickel in admixture with glass may also be used. In manufacture the plug is heated to a temperature of say 1200 to 2000‹F. and an axial pressure of 300 Ibs./sq. in. or higher is applied to the centre electrode. To ensure the sealing of the insulator within the shell the shell may be collapsed in an annular portion between the top thereof and the sealing ledge 17. The earth electrode 11 may be secured as by welding to the shell The gasket 29 may be of nickel or nickel steel alloy. In Fig. 2 the semi-conductor material is formed integral with the firing end on the insulator 5. It may be applied to the end of the insulator during the insulator moulding operation or may be applied as a paint or spray which diffuses into the insulator so as to be integral therewith the application being effected after the hot pressing operation. The plug otherwise is similar to that shown in Fig. 1. After the heating step the pressure is maintained on the electrode until the seal material has cooled sufficiently to solidify. The electrode 11' may be brazed or welded within the end of the shell. Where desired a heat resistant metal gasket of nickel, nickel alloy, silver or the like may be interposed between the insulator face and the firing end of the centre electrode and between the insulator face and the earth electrode.
