Title: New pyrrole derivatives and process for their manufacture
IPC: C07D207/456
Filed: 1965-02-08
Abstract: Novel pyrroline-2,5-diones, substituted in the 3-position by a free or unsubstituted amino-alkylamino group, in which a substituent of the terminal amino group may be linked to a substituent on the nitrogen atom attached to the pyrroline ring or to the alkylene group between the two nitrogen atoms, and in the 4-position by an unsubstituted or substituted phenyl group, and optionally substituted in the 1-position, and their salts (especially their physiologically tolerable acid addition salts), are prepared by reacting the corresponding 3-halo compounds with the appropriate amino compounds, and, if desired, converting a resulting free base into a salt or vice versa, and/or, if desired, alkylating the product if it is unsubstituted in the 1-position. Preferred compounds are those of the general formulae <FORM:1066604/C2/1> AND <FORM:1066604/C2/2> wherein Ph represents a phenyl group optionally carrying one or more C1- 6 alkyl, C1- 6 alkoxy, halogen and/or CF3 substituents, R1 represents H, a C1- 6 alkyl group or a phenyl-C1- 6 alkyl group in which the phenyl group may be substituted in the same way as Ph, R2 represents a di-(C1- 6 alkyl) amino, pyrrolidino, piperidino, morpholino, thiomorpholino, piperazino, N-(C1- 6 alkyl)-piperazino or N-(C1- 6-hydroxyalkyl)-piperazino group, n is 2, 3 or 4, and R3 represents a C1- 6 alkyl or hydroxyalkyl group.  3 - Chloro - 4 - Ph - pyrroline - 2,5 - diones are prepared by the action of a halogenating agent (e.g. POCl3) on the corresponding 3-hydroxy-4-Ph - pyrroline - 2,5 - diones, obtained by condensing a Ph-acetonitrile with an oxalic acid diester in the presence of a strong base and cyclizing the resulting b -Ph-b -cyano-a -oxopropionic ester in the presence of an acid.  1 - Methyl - 3 - chloro - 4 - phenylpyrroline - 2,5-dione is prepared by treating the corresponding 1-unsubstituted compound with caustic soda to form 2-chloro-3-phenylmaleic anhydride and refluxing this with a solution of methylamine in glacial acetic acid.  Pharmaceutical and veterinary compositions, e.g. tablets, dragees, capsules, ointments, creams, solutions, suspensions, emulsions, or animal feedstuffs or feedstuff additives, having antiphlogistic activity, comprise the compounds of the invention in admixture or conjunction with suitable carriers.

Title: Improvements in thermostatically controlled fluid valve
Inventor: TYLER HUGH JEAN
IPC: F16K31/68
Filed: 1957-02-18
Abstract: 822,514. Valves. ROBERTSHAW-FULTONCONTROLS CO. Feb. 18, 1957 [June 28, 1956], No. 5460/57. Class 135. A thermostatically controlled valve 26, Fig. 2, is actuated by a lever 88 mounted on a rotatable crank 78, 80, Figs. 2 and 3, for translatory and rotary movement, and has power means 116 and thermal means 130 urging the lever in opposite directions, means e.g. a cam 150 for rotating the crank to shift the control lever and the valve member relative to its seat 20, and calibration means, e.g. the disc 174 carrying the cam pivot 148, for shifting the position of the cam relative to the crank. When the temperature inside a vehicle increases fluid in a coil or bulb moves piston 130 to rotate lever 88 to close valve 26 and stop flow of water to a heat exchanger, the connection between the valve stem and lever 88 being a ball 42 locked between the lever 88 and a C-shaped member 108 by means of a rocking lever 102 acted upon by a spring 116 which also loads the lever 88. The pivot 80 of lever 88 is formed by one end of a crank 78 the other end of which is positioned by a cam 150 manually rotated against a spring connected at 160 by a Bowden cable connected at 158. The pivot 148 of the cam is carried by a disc 174 journalled in a valve control casing wall 76, the pivot also passing through a bracket 140 hinged at 144 to the wall 76 and carrying a stop 146 co-operating with parts 154, 156 on the cam to limit its rotation. The disc 174 is rotated and locked by the screw 182 in such a position that when the cam is rotated by the Bowden cable to give the highest temperature inside the vehicle, the crank 78 is rotated and the pivot 80 is lowered to such an extent that the valve 26 is closed by the piston 130 at this temperature.

Title: Improvements in automatic stops or brakes for gramophones or the like
IPC: G11B17/02
Filed: 1929-02-20
Abstract: 327,517. Decca Gramophone Co., Ltd., and Cozens, G. A. Feb. 20, 1929. Brakes.-Consists in improvements in automatic gramophone brakes of the kind in which a spring-actuated brake lever is controlled by a latch which is moved, to release the brake, when a member moving with the tone-arm reaches a predetermined position and engages a setting device, the setting member being normally clutched to the latch, but released therefrom by depressing a lever during the operation of resetting the mechanism. The setting member is a lever 16, which is adapted to be engaged directly by a projection, such as a pin 8 on an arm 9, moving with the tone-arm 10. A brake lever 1 is held away from contact with the turntable 3 when a latch 13 engages with a tooth on the brake lever, the tooth being provided by a hardened steel block. The latch 13 and the setting lever 16 are mounted on a common pivot pin 19, with a friction washer 22, Fig. 4, inserted between them. A plate 23 is also freely mounted on the same pin, and carries a blade spring 24 which normally presses the parts 16, 22, 13 together so that the latch and the setting lever are frictionally coupled. A lever 17 is adapted to raise the spring 24 when a press-button 26 on the lever is depressed. The operation of setting the brake is as follows : An initial outward movement of the tone-arm causes a lever 6, engaged by the pin 8, to rock, so that a spring- controlled pawl 11 carried thereby engages a tooth 5 on the brake lever 1 and moves the latter to the " off " position, where it is held by the latch 13. The tone-arm is then moved inwardly until the needle is at the finishing position on the record to be played, and the button 26 is depressed. This frees the lever 16, which is pulled by a spring 12 into contact with the pin 8, whereupon the button 26 is released, leaving the parts 16, 13 clutched together in the appropriate position. Provision for adjusting the brake lever 1 is made by mounting it on a pivot pin 31 by means of an eccentric boss 30, Fig. 5, the flange 29 of which is clamped by a screw 33.
