Title: Improvements in sight-testing cards
IPC: A61B3/06
Filed: 1935-09-14
Abstract: 441,758. Sight - testing apparatus. SCHUR, K., 11, Kreuzstrasse, Memmingen, Germany. Sept. 14, 1935, No. 25578. [Class 97 (i)] A sight - testing card forastigmatism carries a plurality of groups 5...10 of coloured strips, the members of each group being of the same size and the strips in each group differing from each other in colour. The groups are arranged in series of decreasing size either in column as shown or radially. The meridian of the astigmatism of the eye is determined by known methods and the series is placed either parallel or perpendicular to this line by rotation about the pivot 2. The eye is rendered artificially short-sighted and the lens used is changed until the patient can guess correctly the colours in a standard group, e.g. 8. The card is then turned through 90‹ and another lens found for which group 8 is just distinguished. The difference in power of the lenses gives an indication of the power of the cylindrical lens required to correct astigmatism.

Title: Improvements in or relating to new triterpene derivatives, process for preparing same, and applications thereof
IPC: C07H15/256
Filed: 1967-06-02
Abstract: A novel oside and aglycone of the empirical formulae C48H78O20 and C30H48O6 are isolated from the water-alcoholic steep liquor of the plant Centella Asiatica by concentration, crystallization, removal of the crystallization products, evaporation of the residual steep liquor to give the crude oside and, if desired, hydrolysis of this to the aglycone.  The oside is named Madecassoside and has a pasty melting-point at about 220 DEG  C. and [a ]20 of - 19 DEG (c=2.2,H2O). It is a triterpene derivative consisting of the triterpene acid (named Madecassic acid, of m.p. 256-268 DEG  C. and [a ]20+31 DEG  c=1.5, methanol), and probably one molecule of rhamnose and 2 molecules of glucose, linked as in gentiobiose. Methods for the purification of the oside are also described. Specification 923,414 is referred to.  The oside and the aglycone, which are stated to have anti-inflammatory properties and to be useful in the treatment of burns, wounds and ulcers, and of leprelcosis, and in the preparation of skin grafts, may be incorporated in pharmaceutical compositions for oral, parenteral or topical administration.

Abstract: 970,924. Driving helicopter rotors. SUD AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. June 27, 1963 [July 2, 1962], No. 25680/63. Headings B7G and B7W. A helicopter rotor driven by gas turbine engines through mechanical or hydraulic transmission is accelerated from rest by an air turbine powered by air bled from the engine compressors, the mechanical or hydraulic drive being disconnected. As shown, two gas turbine engines 2, 3 drive the rotor shaft 22 through freewheels 31, 32 and a dog clutch 26 operated by a jack 27. To accelerate the rotor, the clutch 26 is disengaged and air is bled from engine compressor tappings, through pipes 4, 5 and 8, through an electrically operated valve 9 to an air turbine LP whose turbine disc 11 is connected by gearing 12-15, an automatically engaging dog clutch 17, and bevel gearing 19, 20, to the rotor shaft 22. The valve 9 is opened by closing a pilot-operated switch 40 and by pressure switches 37 sensitive to the compressor outlet pressures. When the rotor has been accelerated sufficiently, the valve 9 is closed and the jack 27 is operated to engage the clutch 26. Alternatively, the valve 9 may be closed before the rotor has reached a speed corresponding to the engine speed (e.g. maximum continuous r.p.m.), and then the engine speed may be reduced to ensure a smooth engagement of the clutch 26.

Abstract: 464,763. Grinding crank shafts &c. NORTON CO. Sept. 23, 1935, No. 26286. Convention date, Sept. 29, 1934. [Class 60] [Also in Groups XXII and XXIV] In a machine for grinding crank shafts or other rotatably mounted work-pieces, means are provided for simultaneously moving the slide carrying the grinding wheel and a worksteadying rest towards or away from the work-piece. In the machine shown the operation of a valve 92 by a lever 93 admits fluid from a pump 91 either through a control valve 97 to a cylinder 100 to traverse the work table 15 or through a control valve 95 simultaneously to cylinders 107, 118 to move the slide 11 carrying the grinding wheel 20 and a slide 116 carrying a work-steadying shoe 115 towards or away from the work 32. The work 32 is clamped in opposed rotating heads 30, 31 constructed as described in Specification 351,522 and adjustably mounted on the table 15. The heads 30, 31 are rotated by chain-gearing 46, 41, an intermediate shaft 43, and a clutch 38 from a power shaft 37. The pistons 55 and cylinders 56 for operating the clamping jaws of the heads 30, 31 may be arranged in axial alignment with the work-rotating spindles instead of being offset as described in Specification 351,522. The work table and wheel slide may be operated manually by handwheels 60, 68 through suitable gearing. The slide 116 is movable by a hand-operated screw 123 relatively to its operating member 122. In order to prevent the table being traversed while the work-shoe 115 is engaging the work, operation of the valve 97 is normally prevented by the engagement of a pin 164 on its operating lever 103 with a spring-pressed lever 160 pivoted to the steady-rest frame 117. When the shoe 115 is retracted a pin 165 on the slide 116 moves the lever 160 out of engagement with the pin 164. A manually operated valve in the pipe line to the cylinder 118 allows operation of the wheel slide 11 independently of the shoe 115 to grind the rough spots off the work at the start of the grinding operation. The splash guard comprises a fixed lower member 140 and a hinged upper member 141, removal of the work being facilitated by the upper member 141 being turned to the horizontal position against the resistance of springs 144, 145 by a projection 146 on the slide 116 when the shoe 115 is retracted. Specification 355,650, also is referred to.
