Title: 5-(pyridinyl)-2(1H)-pyridinones, useful as cardiotonic agents and their preparation
IPC: C07D401/04
Filed: 1980-11-26
Abstract: 1-R1-3-[unsubstituted, amino, cyano, carbamyl, halo, lower- alkylamino, di-(lower-alkyl)amino, lower-acylamino carboxy or lower- carbalkoxy]-6-(lower-alkyl)-5- (optionally lower-allyl substituted pyridinyl)-2(1H)-pyridinones or pharmaceutically- acceptable acid-addition or cationic salts thereof are useful as cardiotonic agents, where R1 is hydrogen, lower-alkyl or lower- hydroxyalkyl. 1-R1-3-amino-6-(lower- alkyl)-5-(pyridinyl)-2(1H)-pyridinones are prepared by hydrolyzing the corresponding 3-cyano compounds to produce the corresponding 3-carbamyl compounds and reacting the latter with a reagent capable of converting carbamyl to amino. The 1-R1-3-cyano-6- (lower-alkyl)-5-(pyridinyl)-2(1H)- pyridinones are prepared by reacting (pyridinylmethyl) lower-alkyl ketones with dimethylformamide di-(lower- alkyl)acetal to produce 1-(pyridinyl)-2- (dimethylamino)ethenyl lower-alkyl ketones and reacting said ketones with N-R1-O-cyanoacetamide to produce the 1-R1-3-cyano-6-(lower-alkyl)-5- (pyridinyl)-2(1H)-pyridinones. Also shown are the conversions: of the 3- cyano compounds to the 3-H and 3- carboxy compounds; of the 3-H compounds to the 3-halo compounds; of the 3-halo compounds to the 3-[mono- (lower-alkyl)-or di-(lower-alkyl)- amino]compounds; of the 3-amino compounds to the 3-lower-acylamino or 3-[mono-(lower-alkyl)- or di-(lower- alkyl) amino] compounds, and of the 3-carboxy compounds to the 3- carbethoxy compounds.

Title: Phase detector circuit
IPC: H03L7/08
Filed: 1981-02-24
Abstract: Horizontal sync signal is applied to a phase detector (23) as well as to a gate circuit (25). The output of a VCO (27) is applied via a divider (28) to a second input terminal of the phase detector (23) which outputs a pulse having a pulse width proportional to the phase difference. This phase detection pulse is applied through a buffer (24) to a gate circuit (25). In the gate circuit (25), the current path from the phase detection pulse input terminal to the gate output terminal is held conductive during the period of the gating pulse, and an output pulse whose duty ratio varies according to the pulse width of the phase detector output is obtained. This output pulse is smoothed through a filter (26) to be applied as an oscillation frequency control voltage input to the VCO (27). <IMAGE>

Title: Clutch disc for a motor vehicle friction clutch
Inventor: LUTZ DIETER
IPC: F16F15/123
Filed: 1983-06-21
Abstract: A clutch plate (15) is secured fast with two cover discs (7, 9) mounted on a hub flange (5). Compression springs (39) stressable on relative rotation of the hub flange (5) and the cover discs (7, 9) damp torsional vibrations under load. Between the cover disc (7) and the hub flange (5) an expanding ring spring (19) is arranged which is fixed with its one end (21) to the disc (7) and its other end (23) to the hub flange (5). The spring (19) not only damps torsional vibrations but also generates an axial initial force which stresses the cover disc (9) through a friction ring (17) axially against the hub flange (5). The compression springs (39) are seated in windows (35) of discs (27, 29) which are mounted fast in rotation but with rotational play on the hub flange (5). A spring (45) between the discs (27, 29) braces the discs through friction rings (41, 43) against the cover discs (7, 9). The damping effect of the springs (39) and of the friction linings (41, 43) becomes effective only after the rotational play of the discs (27, 29) on the hub flange (5) is taken up. <IMAGE>

Title: Forward Slip Control Device
Inventor: SHIOZAKI HIROYUKI
IPC: B21B37/00
Filed: 1984-03-13
Abstract: A forward slip control device for a rolling mill having a pair of rolls (1, 2) in which the forward slip fH of a strip (3) is calculated (12) and is compared with a set value fH<I>. In response to a signal representative of difference  DELTA VRL between these values, the peripheral velocity VRL of a work roll (1) is changed, thereby controlling the forward slip. As shown, the lower roll 2 rotates at a constant velocity, measured at 15 and compared in an arithmetic unit 12 with strip exit velocity V2 to obtain slip. The desired value for this may be at or nearly zero. Any slip error adjusts the velocity of the upper roll 1, which in any case is slower than roll 2. In an alternative embodiment (Fig. 4) both rolls rotate at the same speed driven by a single motor whose speed is adjusted in response to slip error. <IMAGE>
