Title: Improvements in or relating to optical measuring devices
Inventor: DIETRICH CORNELIUS FRANK
IPC: G01M11/02
Filed: 1956-10-26
Abstract: 831,201. Optical testing apparatus. OPTICAL MEASURING TOOLS Ltd. Jan. 24, 1958 [Oct. 26, 1956], No. 32751/56. Class 97(1) Optical apparatus for determining distances (e.g. focal length of a lens or height of an object) comprises a lens holder movable relatively to an object holder for focusing and, on the side of the lens holder away from the object, two optical elements for bringing together two beams passing through different portions of the lens in the holder so that, when said lens is in focus, the images formed by these beams are superposed. For determining the dimensions of a work-piece 12, the apparatus may take the form shown in Figs. 1 and 2 with the work-piece mounted below the objective holder 19 of a microscope on a slide movable on a table 44 which is itself movable at right angles to the slide on a base 31, each movement being controlled by a screw against which the slide or table is spring pressed. The microscope is clamped to a carriage 37 movable vertically by fine and coarse adjusting knobs and having a projection 58 contacting a feeler 57 slidably operating a dial indicator 56. The objective holder 19 accommodates a meniscus lens 15 cemented to a concavo-convex objective 11 having a central reflecting portion 14 and peripheral reflecting portions 13 so that light from the work-piece 12 is doubly reflected within the objective and emerges therefrom as a double beam 16, 17. Behind the objective is a prism 21 having inclined faces 22, 23 in the path of each beam 16, 17 so that the latter pass to the eyepiece 28 along the same path through a lens 26 and prism 29. The two beams form superposed images when the objective 11 is correctly focused on the work-piece, the reading on dial 56 at this time indicating the dimension of the work-piece. In the form shown in Fig. 4, an illuminated scale 74 is carried by a slide 63 and a holder 60 for a lens 80 is carried by a slide 61, the slides 61, 63 being movable on parallel guides 65, 66 fixed to end castings 67, 68 which are movable on rollers 71 in a direction perpendicular to the length of the guides. Slide 61 carries a movable crossslide 83 which supports an iris diaphragm 88, a mirror 84 and a beam-combining cube 85. The mirror and cube serve to combine two parallel beams from lens 80, the combined beam passing to an optical goniometer 64 mounted on a divided circle 90. With the scale 74 in the focal plane of lens 80, cross-slide 83 is moved to bring the diaphragm 88 into the light path and the goniometer is used to measure the angle # between two of the lines of the scale which are symmetrically disposed with respect to the optical axis of the lens. The focal length F of lens 80 is then deduced from the relation F = S, where S 2 tan # is the distance between said two lines.

Title: Improvements in or relating to fluid supply systems
IPC: G05D7/03
Filed: 1953-12-03
Abstract: 735,845. Valves. GENERAL MOTORS CORPORATION. Dec. 3,1953 [Dec. 19, 1952], No. 33577/53. Class 135. A valve arrangement for maintaining equality or proportionality of fluid flow in a number of conduits fed from a common source 46, and applicable to gas turbine fuel systems, comprises a spring-loaded piston 40 controlling a triangular flow restrictor port 32 in each conduit, a spring-loaded pressure drop control valve 82 in one conduit adapted to maintain a higher pressure than is liable to be developed in the conduits under ordinary operating conditions, and diaphragm actuated sleeve valves 60 in each of the other conduits, only one of which is shown. A passage 78, 76 leads from a point between the valve 82 and its associated restrictor port 32 to chambers 70 below the diaphragms whilst passages 72 connect the upper side of each diaphragm with a point between its associated valve 60 and restrictor port 32. Thus, each sleeve valve operates to maintain the same pressure drop across its associated restrictor port as occurs across that leading to the valve 82. The triangular restrictor ports may have equal apex angles for obtaining equal flows or unequal angles for unequal but proportional flows. The upper side of the piston 40 is vented by a passage 50 so that the piston moves upwardly to increase the opening of the ports 32 with increasing inlet pressures. Small quantities of fuel pass from the inlet 46 through a filter 100 and passages 102, 104 to the surfaces of the piston 40 and sleeve valves 60 to prevent the introduction of foreign matter. In a modification, pressure fluid from an independent source may act in the chambers 70, or alternatively, where one fuel nozzle has a higher resistance to flow than the others, its upstream pressure can be applied in the chambers 70 instead of the pressure before the valve 82.

The pointer 12 is pivoted at its mid-point on a plate 14 secured to a rod adapted to be moved up and down in a slot 24 by a pin projecting through the base 16, while a spring 19 fixed to the plate 14 biasses the pointer 12 into contact with a plate 22 mounted on a rod adapted to be moved up and down in a slot 28 by another pin, thus allowing the pointer to pivot. The cursor D is mounted on a member 36 which slides on a rod 38 and has a pin projecting rearwardly to engage a slotted connecting-member which is pivoted at 50 and has an oval aperture in which moves an eccentric on whose shaft is fixed a milled wheel 48 by means of which the cursor can be shifted laterally. In a modification the time scales are placed to one side of the pointer, say the left, and the scales of heights are marked on the cursor. In use the pointer is set with the left-hand scale at the right-hand end of the time scales and the cursor is then moved to the left to the appropriate time mark when the pointer indicates the required height on the right-hand scale. Adjustments may alternatively be made by quick pitch screws, index lines on transparent parts may replace " straight edges " and vice versa and a recording drum may be provided settable by operations corresponding to the setting of the pointer and cursor.
