Abstract: The invention comprises compounds of the formula <FORM:0982612/C2/1> in which Py represents a pyridyl-(3)-group, R represents a lower alkyl, hydroxy-lower alkyl, lower alkoxy-lower alkyl, aminoalkyl, mono- or di-lower alkylamino-lower alkyl, alkyleneimino-lower alkyl, aza-alkyleneimono-lower alkyl, oxa-alkyleneimino-lower alkyl or cycloalkyl group, or a phenyl, phenyl-lower alkyl or pyridyl group which may be substituted in the aromatic nucleus by one or more lower alkyl or lower alkoxy groups or halogen atoms (including trifluoromethyl), or an N-alkyl piperidyl group and R1 represents a hydrogen atom, a lower alkyl group or a phenyl group which may be substituted by one or more lower alkyl or lower alkoxy groups or halogen atoms (including trifluoromethyl), and N-acyl derivatives, quaternary ammonium derivatives and acid-addition salts thereof.  The compounds are prepared by reacting a pyridyl-(3)-carbonyl acetonitrile, which may be monosubstituted, with a 2-R-hydrazine, preferably in the presence of a condensing agent and a diluent.  The N-acyl derivatives, quaternary ammonium compounds may be made in conventional manner, e.g. by reacting the compounds with reactive derivatives of aliphatic, alicyclic or heterocyclic acids, reactive derivatives of C1- 7 alkanols or benzyl alcohols, and inorganic and organic acids, respectively.  Pyridyl - (3) - carbonyl - acetonitrile starting materials are prepared by reacting a pyridyl-(3)-carboxylic acid ester with a possibly monosubstituted acetonitrile. Pharmaceutical compositions having an anti-inflammatory, anti-pyretic, anti-allergic and possibly hypotensive or coronary-dilating action for enteral or parenteral administration, comprise a compound of the invention together with a pharmaceutical carrier.  The compositions may be formulated as tablets, dragees, capsules, solutions, suspensions or emulsions.

Title: Improvements in or relating to transistorized receiving circuit arrangements
IPC: H04B1/28
Filed: 1959-01-02
Abstract: 891,230. Transistor radio receivers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 2, 1959 [Jan. 7, 1958], No. 204/59. Class 40(6). The necessity for neutralizizing the intermediate frequency amplifier stages of a transistor superheterodyne radio receiver is avoided by designing the input transformer and output transformer of the intermediate frequency amplifier to produce an appropriate mismatch and by using collector to base D.C. feedback. The Figure shows a receiver comprising a self oscillating frequency changer 1, an intermediate frequency amplitier 4, detector 5 and an audio frequency amplifier 6. The I.F. input transformer has a low Q primary circuit and a relatively high Q secondary circuit with a tap 11 which loosely couples the circuit to transistor 7. The output transformer has a high Q primary circuit 14 loosely coupled at 13 to the output transistor and a low Q secondary circuit 15. In addition, the intermediate frequency transformer 12 has a high Q primary winding and tappings loosely coupling the transformer to the adjacent transistors. Negative D.C. feedback is provided by collector resistors 16, 18 and feedback resistors 17, 19, the collector resistances being of sufficient magnitude to drop substantially half the supply voltage. It is suggested that inductive taps could replace the capacitive taps.

Abstract: 1,109,987. Displaying data from stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. 13 Jan., 1967 [25 March, 1966], No. 2055/67. Heading G4C and G4H. A cyclic trace display device e.g. a television display 33 (Fig. 1) is selectively fed with data from a cyclic buffer store 21, control means supplying data from every nth (e.g. 2nd) block location to the display, the blocks being displayed on successive lines. In the embodiment described data from a keyboard 10 is converted to video and binary coded decimal form in a composer 12 and parallel to serial converter 13 respectively and read in, on leads 20, 22 (Fig. 9), when a write pulse enables AND gates 116, 117, via OR gate 120 and sequentially enabled AND gates 121- 124, to one of four parallely connected delay lines 110-114. Output signals via AND gates 127-130 and OR gate 138 are supplied (1) to the T.V. display via an AND gate enabled except during vertical re-trace, (2) to marker bit control 55 and (3) to AND gate 119 for re-entry into the store. During the first cycle of the delay line blocks of data, 1, 2, ... 78 (Fig. 2) are displayed, blocks 79 to 143 being fed from the delay line during horizontal retrace. During the second cycle blocks 79 ... 143 are displayed and during vertical re-trace binary coded data in blocks KB1 ... KB12 is read out. During a write in operation marker bits are inserted-in the last bit of the last byte of data-the marker bit control 55 prior to a writing operation destroying old marker bits. When the marker bit control locates a binary coded decimal marker bit during vertical retrace the output of OR gate 134 becomes positive and a bit counter is then enabled to start read in of data, the AND gate 119 being closed to prevent re-entry of the marker bit. The delay lines may be cleared by depressing switch 140 and before new data is read in one initial marker bit is inserted in each block in the last bit position by depressing switch 144 which allows properly timed pulses on line 145 to be stored. When data is written in the initial marker bit is destroyed.
