Inventor: LEE T B K
IPC: C07B61/00
Filed: 1991-01-21
Abstract: A process for the stereoselective synthesis of [R]- and [S]-2,3-dihydro-1,3-dimethyl-2-oxo-1H-indole-3-acetonitriles comprises reacting racemic and 5-alkoxy-substituted (+/-)-1,3-dimethyloxindoles with a halogenated acetonitrile in the presence of a substituted N-benzyl cinchoninium, quinidinium, cinchonidinium, or quininium catalyst. The resulting alkylated oxindoles can be converted to primary amines by catalytic reduction in the presence of hydrogen gas. One of the primary amines, such as enantiomers of 3-(2-aminoethyl)-1,3-dihydro-1,3-dimethyl-5-methoxy-2H-indol-2-one, can be enriched by contact with a chiral tartaric acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The product can be used in the synthesis of stereospecific forms of physostigmine and related compounds having pharmaceutical activity.
Patent AT-A35592-A (AT)
Inventor: GEDL KARL ING
IPC: H04N5/765
Filed: 1992-02-25
Abstract: In a video recorder (1) for the recording and reproduction of picture signals in standard-play modes and long-play modes a reconverted picture colour signal supplied by a frequency-conversion stage (70) is passed through a delay device (84) having a delay of one line period in order to compensate for reproduction-dependent time errors during multi-speed reproduction of a long-play recording. In such a video recorder (1) a rectangular detection signal of half the line frequency is supplied to an output (76) of a phase detection stage (73) which detects the phase of the burst signal in the reconverted picture colour signal, which detection signal is applied, via a connection (91), to a modulator (36) for the modulation of non-modulated character signals as a control signal (S2) for the modulator (36), which generates modulated character signals suitable for insertion into the reproduced picture signals. The connection (91) includes a switching device (93) which enables a further delay device (94) having a delay of one line period to be included in the connection (91) in the case of multi-speed reproduction of a long-play recording by the video recorder (1), as a result of which the control signal (S2) is delayed by the same time as the picture colour signal during such a reproduction mode, which ensures that the picture colour signal and the character colour signal always remain locked to each other in the same way in all the modes of operation. <IMAGE>

Title: Ball crank connection
IPC: F16C11/06
Filed: 1921-01-03
Abstract: 156,206. Smith, W. S. June 30, 1919, [Convention date]. Joints for link-work.-In ball-joints for link-work, the socket-members are constructed with the "grain" of the metal substantially parallel to their working-faces, so that they rapidly become polished by wear. With this object, and for lightness, they may be pressed from sheet-metal. As applied to the joints of an automobile steering- gear, the preferably tubular drag-link 1 has sockets 3 at each end containing the ballend 5 of a joint-pin 6, and against the balls are pressed, by springs 13, socket-members 10, 11<1> and 10, 11 with spheroidal working-faces. The socket-members may have depressions 17 to contain grease and corresponding projections 18 to serve as spigots for the spring &c. The piece 11 and left-hand spring-abutment 15 are formed as screwed plugs, whereby the springs may be adjusted, and are slotted at 20 for split pins 19. To assemble the joint, the ball-ends 5 are passed through the large openings 8 of key-hole slots 8, 9 in the sockets 3.

Title: Improvements relating to foldable tops for convertible automobiles
IPC: B60J7/12
Filed: 1955-01-05
Abstract: 764,514. Vehicle folding hoods. OPEL AKT.-GES., A. Jan. 5, 1955 [Jan. 7, 1954], No. 288/55. Class 108(1). A folding hood comprises hoops connected at each side by a lazy tong linkage 31-41, which linkage is collapsable against a rear plate 27, Fig. 1, and is supported on side rails 26 by rubber cushions 49, 50, resting in recesses 51 Figs. 4 and 5. The front bow 47 rests on the windscreen frame also by the interposition of a rubber cushion. Due to the fact that the top rests on the rails 26 the lazy tongs may be extended to the hood open position until the joints 21, 20, 18, 17, 15, 14, 12 and 11 touch each other, but in order that the tongs may follow the curvature of the rails 26 the spaces between the upper tong joints are greater than the spaces between the lower joints. The hoops 43-46 have hinge plates 53 welded to their ends, and the plates are riveted to the top joints and bent over at right angles to form lugs 54 which maintain the hoops erect. The bolts holding the plate 27 may be shifted in slots in the body structure so that the plate and folding top may be accurately mounted on the body. The position of the diagonal hinge joints of the tongs do not coincide with the intersections of the geometrical diagonals of the trapeziums formed by the links, thus permitting greater spacing of the joints 11, 14, 17 and 20 when the hood is folded. To collapse the hood the bow 47 must first be lifted to move the joint 21 over centre and allow the bow 42 to be forced or pulled backwardly.
