Title: Improvements in or relating to variable speed drive transmissions
IPC: F16H3/00
Filed: 1963-01-09
Abstract: 1,025,591. Change speed and reverse gear; clutch combinations; change speed and clutch control. FRANCAISE DU FERODO S.A. Jan. 9, 1963 [Jan. 9, 1962], No. 1062/63. Headings F2C, F2D and F2L. A hydromechanical reverse gear for a motor vehicle comprises two coaxial intermediate shafts 22, 22<SP>1</SP> respectively geared directly at 23, 24 and through an idler 26 to an output shaft and which shafts 22, 22<SP>1</SP> are, for forward and reverse ratios, selectively clutched at 19, 19<SP>1</SP> to the turbine T of a hydrodynamic torque converter C, the impeller P of which is fast with an input driven casing 12. As shown, a two-speed gear 80 is provided between the reverse gear and output shaft 11. Torque converter control.-The torque transmitted by the torque converter C is varied by inserting a baffle 50 into the working circuit. The converter casing 12 is supplied with liquid from a pump 38 at an intermediate pressure determined by a relief valve 70. The baffle 50 may, as shown, be moved left into the working circuit by supplying high pressure liquid from the pump 38 through a manually controlled valve 73 and line 67 to a servomotor 61. The baffle 50 is returned to the position shown by the intermediate pressure liquid in the casing 12 when the valve 73 vents the line 67 through a low pressure relief valve 77. In Fig. 1 (not shown) the baffle 50 is moved manually and may be linked to the vehicle brake pedal so that initial movement of the pedal operates the baffle and further movement of the pedal applies the brakes. Friction clutches and control.-The clutches 19, 19<SP>1</SP> may have slightly conical presses and reaction plates. As shown, the clutches are biased towards engagement by intermediate pressure liquid in a chamber 31 between the presser plates, which chamber 31 communicates with the interior of the casing 12 at 32. A clutch control valve 44 selectively supplies high pressure fluid from the pump 38 through lines 43, 43<SP>1</SP> to clutch chambers 41, 41<SP>1</SP> to oppose the intermediate pressure in chamber 31 and disengage the clutches. The valve 44 has three positions,one in which it supplies pressure liquid to both chambers 41, 41<SP>1</SP> to disengage both clutches 19, 19<SP>1</SP> and two others in which is supplied pressure liquid to one chamber 41 or 411 and vents the other 41<SP>1</SP> or 41. In Fig. 5 (not shown), an additional electromagnetically operated valve 85 connects both clutch chambers 41, 41<SP>1</SP> to the high pressure line to disengage the clutches during ratio shaft of the gear 80. In Fig. 1 (not shown) the clutches are biased towards a disengaged position by Belleville springs 28, 28<SP>1</SP> and orifices 30, 301 connect the chamber 31 with chambers 41, 41<SP>1</SP>. The clutches are disengaged by blocking the outflow of liquid from the chambers 41, 41<SP>1</SP>.

Patent GB-1026739-A (GB)
Title: Light-transmitting device
IPC: H01S5/50
Filed: 1965-01-11
Abstract: A light-transmitting device comprises an optical amplifying element, e.g. an electroluminescent GaAs diode, and an optical attenuating element in series, at least one of the elements having a transmission ratio which varies with the intensity of the light applied thereto, the overall transmission ratio of the device being dependent upon the order in which light passes through the elements.  The attenuating element may be a GaAs crystal, whose transmissivity varies with its temperature, and which is heated by the light passing through it, or a photochromic compound such as 2-(2,4-dinitrobenzyl) pyridine.  The device enables a substantially constant light output to be obtained from a light input signal of widely varying strength.  In one embodiment, two such devices are used, their outputs being directed on to a laser, and being such that only one output is insufficient, but both together are sufficient, to quench the laser.

Title: Improvements in or relating to apparatus for aligning x-ray diffraction goniometers
IPC: G01N23/20
Filed: 1955-01-18
Abstract: 777.275. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 18, 1955 [Jan. 18, 1954], No. 1517/55. Class 98(1) X-ray apparatus for diffraction examination of crystalline substances having an X-ray tube tower 4, Fig. 2, and a diffrac-- tion goniometer 6 aligned with respect tothe focal spot 2, is characterized in that the X-ray tube tower has at its X-rayemerging side a vertical reference surface parallel to the axis of the X-ray tube and perpendicular to the central ray of the X-ray beam, with an assembly comprising an angle bracket 10 having one surface secured to the reference surface in a manner allowing vertical adjustment of the assembly. As shown, the bracket 10 has a vertical support 12 movable in contact with the reference surface by an adjusting screw 16, and may be locked in position by a set screw 18. The alignment surface 14 of the bracket 10 makes an angle of just less than 90 degrees, preferably 87 degrees, with the vertical support 12. A jig 22 (Fig. 1), placed on surface 14 has upstanding ears 24, 26, having respectively a slit 32, and a fluorescent screen 34 with cross-lines 36 intersecting at a distance from surface 14 equal to the distance of slit 32 from the surface. The bracket 10 is then adjusted vertically until the image of slit 32 falls on the cross-wires 36. This ensures that the X-ray beam defined by slit 32 is at an angle of 3 degrees to the specimen. Jig. 22 is then replaced by an alignment bar 38, of L-shaped cross-section and having a U-shaped bracket 44 with a screw 46 for clamping the specimen support 42, after a vertical line 54 thereon has been aligned with a guide line 51 on the top surface of bar 38. The bar has cut-out portions 50, 53 at its ends, which are fitted respectively against a housing 58 for a slit from which X-rays emerge, and a housing 60 for a slit through which X-rays pass to a detector. Also, the edge of bar 38 is aligned with the edge 15 of surface 14, and 'a line 52 on the bar 38 is aligned with a line 56 on edge 15. This aligns the goniometer. The bar 38 is removed, and a jig is fixed to the specimen holder. The jig has an aperture through which the X-ray beam passes, when the holder is at 90 degrees thereto, to the detector slit in housing 60, which is then adjusted for maximum detector reading to determine its zero position. A further jig is then used, having apertures which, when aligned, determine the zero position of the specimen holder.
