Title: Improvements in or relating to muscle relaxant and analgesic compositions
IPC: C07D215/36
Filed: 1963-07-23
Abstract: The invention comprises carbostyril compounds of the general formula <FORM:1002665/C2/1> wherein Y is -CH=CH- or -CH2-CH2-; X is oxygen or sulphur and R2 is lower alkyl, or, when Y is -CH2-CH2-, hydrogen. Compounds of the above general formula, may be prepared by the reaction schemes outlined below <FORM:1002665/C2/2> R represents trifluoromethyl, R1 is hydrogen, and X is an anion.  The term "lower" refers to groups having 1 to 4 carbon atoms.  The N-oxide of 6-trifluoromethylquinoline is prepared by action of hydrogen peroxide on quinoline and then treated with acetic anhydride before hydrogenation to give 3,4-dihydro-6-trifluoromethylcarbostyril.ALSO:Pharmaceutical compositions having muscle relaxant and analgesic activity comprise a pharmaceutical carrier in association with a carbostyril compound <FORM:1002665/A5-A6/1> wherein Y is -CH = CH- or -CH2-CH2-; X is O or S; R is hydrogen, halogen, hydroxy, nitro, amino, mono-lower alkyl amino, di-lower alkyl amino, acetamido, trifluoromethyl, lower alkyl, lower alkoxy or ethoxycarbonyl; R1 is hydrogen or, together with R, dihalogen, dihydroxy, diloweralkoxy or methylene-dioxy; and R2 is lower alkyl or, when R is -CH2-CH2-, hydrogen.  "Lower" refers to groups having 1 to 4 carbon atoms and "halogen" denotes chlorine, bromine or fluorine.  Conventional solid or liquid carriers may be used, together with a sustained release material.  The compositions may be used in the forms of a tablet, capsule, troche or lozenge, and their administration may be effected parenterally or orally.

Title: Improvements in or relating to disc brakes for vehicles
Inventor: EDGE STANLEY HOWARD
IPC: F16D55/2255
Filed: 1952-11-19
Abstract: 730,053. Disc brakes. CLAYTON DEWANDRE CO., Ltd. Oct. 15, 1953 [Nov. 19, 1952], No. 29249/52. Class 103 (1). In a "spot-type" disc brake, the braking means consists of a fluid-pressure operated cylinder and piston device 1, disposed on one side and adjacent the periphery of the brake disc 2 and with its axis arranged parallel to the axis of the disc, the cylinder of the device 1 being supported by a fixed carrier plate 4 by means of a link 5 pivotally connected to a bifurcated lug 10 mounted on the cylinder and to a second lug 12 provided on the face of the carrier plate. The cylinder 3 carries a clawlike bracket 6 which projects from the cylinder and extends over the periphery of the brake disc 2 and carries a flat pressure plate 7 lined with a pad 8 of friction material. The piston 14 within the cylinder 3 is provided with a rod 15 which extends through the open end of the cylinder and has pivotally connected to it a pressure plate 16 provided with a pad 17 of friction material. At the same pivotal connection, i.e. pin 18, one end of a link 19, which passes through a slot in the wall of the cylinder, is pivotally connected ; the other end of the link being pivotally connected by pin 20 to a lug 21 fixed to a tangential extension 22 of the fixed carrier plate 4. In operation, the application of fluid-pressure to the working chamber 24 through port 23 causes the piston and the cylinder to be moved in opposite directions so that the pads on the pressure plates are forced thereby into clamping or gripping engagement with both sides of the brake disc simultaneously. By varying the perpendicular distances between the axis of the pivot 20 and the plane of the braking surface on which the pressure plate 16 acts, and between the axis of the pivot 20 and a line drawn perpendicularly to the plane of the said braking surface and passing through the axis of the pivot 18, the pressure plate 16 can be arranged, depending upon the direction of rotation of the brake disc to act either in a self-energizing manner so as to increase its frictional engagement with the brake disc, or in a trailing manner so as to assist its disengagement from the disc when the working chamber 24 is exhausted to atmosphere upon release of the brakes.

Abstract: 962, 044. Automatic voltage control. C. O. OLSSON. Aug. 3, 1962 [Aug. 4, 1961], No. 30081/62. Heading G3R. A direct voltage derived from an unstabilised supply source 1a, 1b, is maintained constant at output terminals 5 by means of a series transistor 2 controlled in known manner by a circuit including a comparator 4 and an amplifier 3. The two parts 1a, 1b of the supply source are interconnected by a power transistor 6 shunted by a resistor 7, and the base of transistor 6 is connected to one output terminal and the emitter of transistor 2 by way of a variable resistor 8. The arrangement is such that the transistor 6, which is cut-off under low-current conditions, is rendered conductive when the current increases; the potential drop across resistor 7 is thus adjusted so that the voltage across transistor 2 approaches the voltage across the part 1a, which latter voltage is arranged to be relatively low. The transistor 2 is thus protected against over-heating and a higher current may be obtained for a given voltage range.
