Title: Improvements in or relating to focimeters
Inventor: SAICH ARTHUR MARCUS
IPC: G01M11/02
Filed: 1965-01-21
Abstract: 1,140,352. Focimeters. HANWELL OPTICAL CO. Ltd. Feb.22, 1966 [Jan. 21, 1965], No.2691/65. Heading G2J. A focimeter comprising a graticule D, an optical system for projecting an image of the graticule on to a screen C and means for supporting a spectacle lens under test between the graticule and the screen, is provided between the lens support and the screen C with an optical correcting element L which is movable transversely of the optical axis to ensure that the graticule image is centred on the screen C. The spectacle lens is supported at the free end of an objective tube A<SP>2</SP> which is mounted in a wall of the focimeter housing A. Light passing from a source B through the graticule D, the objective F, and the lens under test is directed by a mirror K outside the focimeter housing towards an aperture therein which is closed by a low powered negative lens element L. This lens element is releasably clamped to the housing wall and is adjustable in a plane at right angles to the optical axis. When the lens under test is in position, the graticule D, is moved along the optical axis until a sharp image appears on the screen C, the distance moved being a direct measure of the power of the lens. The distance may be indicated by a scale E6 fixed to the graticule D, an image of which scale is projected by a further optical system on to a screen C' so as to register with a pointer marked on the screen C'. The graticule D may comprise an opaque disc bearing a plurality of double rows of transparent dots arranged radially of the disc. In order to find the axis of astigmatism in the lens under test the graticule is rotated until the dots of the graticule image merge into lines. Means may be provided for marking the horizontal axis of the lens under test during the test.

Title: Improvements in or relating to direct current motor control
IPC: H02P7/285
Filed: 1959-01-27
Abstract: 885,563. Automatic speed control systems. KOPPERS CO. Inc. Jan. 27, 1959 [Jan. 27, 1958], No. 2917/59. Class 38 (4). When the speed of motor 10 deviates from the value set on dial 194, the voltage derived from tachometer generator 126 and applied to potentiometer 153 becomes unbalanced with regard to a reference voltage obtained through rectifier 167, so that relay 197 or 198 is energized according to whether the speed is below or above the desired value. A reversible pilot motor 89 then operates at constant speed to change the tappings on transformer 29 from which the motor 10 is supplied with rectified current. When the speed of the motor 10 reaches the set value, the relay is de-energized and the pilot motor is stopped.

Methyl- N-p-t-butylbenzenesulphonylcarbamate used as an intermediate is prepared by the action of methyl chloroformate on t-butylbenzenesulphonamide.  N:NDiphenyl-N1- (4-methylcyclohexyl)-urea is made by reacting diphenylcarbamyl chloride and 4-methyl-cyclohexylamine. Trans-4-methyl-cyclohexyl-urea is made by treating 4-methyl-cyclohexylamine (trans) with potassium cyanate.  N- (p- Methylbenzenesulphonyl)- N1- (4-methylcyclohexyl) isourea methyl ether is made by treating methylcyclohexyl urea with dimethyl sulphate and p-toluenesulphonyl chloride. 4-Methylcyclohexyl-isocyanate is made by treating 4-methyl-cyclohexylamine with phosgene. p-Methylbenzenesulphonyl-carbamoyl chloride is made by treating the corresponding isocyanate with phosgene.  The 4-methyl-cyclohexylamine salt of N:N1-bis-p-methylebenzenesulphonyl urea is made by reaction of the two components.  Pharmaceutical preparations having hypoglycaemic action comprise the sulphonyl ureas of the invention in admixture or conjunction with a carrier, preferably in a form suitable for oral administration (e.g. tablets) giving a dosage unit of 0,2-2 grams.

The links 23 are pivoted to a stationary platform, and the links 26 to a member 28 which, when the rods 18 are moved inwardly, is raised to force the plate 40 upwardly. Before such pressing, the top of the mould cavity is closed by a cross-head 60 connected by two sets of linkages 77 to a fixed beam 53; a double acting ram 90 brings the linkages to an over-centre position to effect mould closure. The linkages are locked in this position by ram-rods, not shown, passed through corresponding bores in fixed brackets 83 and links 71. Vertical movement of the cross-head 60 is assisted by rams 110. The slurry feed mechanism includes a valve controlled outlet in an inclined feed duct 120 below which is reciprocally supported a feed trough which is extended during the feed stage and retracted during pressing. After the pressing operation, the cross-head is raised and cylinders 34 raise the plate 40 so that the moulded article is raised above the mould cavity and finally removed by a wheeled pusher 105 on the end of a horizontal ram-rod.
