IPC: G02B21/00
Filed: 1957-07-17
Abstract: 885,507. Gauging departure from standard form. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 17, 1958 [July 17, 1957; Nov. 13, 1957], Nos. 22613/57 and 35355/57. Addition to 882,075. Class 106 (2). [Also in Group XX] In a method of testing the profile of a workpiece 5, the profile is tracked by a feeler 4 to cause relative positioning between corresponding points of representations of profiles 40a, 40b exhibited on a screen 11, the distances between these corresponding points representing dimensional differences between parts of the workpiece and corresponding parts of a selected profile, two of the corresponding points being indicated at any instant by an index means 30. A stylus 4 is first used to trace the outline of a standard shape 5 and at the same time a scriber (not shown) traces a replica 40 of the outline on a smoked glass 10 carried by the stylus holder 6. Whilst this is happening, a similar outline 40a is traced on a photographic plate 11, also carried by the holder 6, by a spot of light from a lamp 31, which passes through a lens 32 and a slit 30. The slit 30 is moved by a linkage 27, 28, so that it is always maintained parallel to a follower 13 running on a fixed track 12, the track being so aligned that the follower 13 remains perpendicular to that portion of the outline 5 which is being traced at any moment. When a workpiece 5 is substituted for the standard profile a ray of light from the lamp 31 passes through the trace 40 and a magnifying lens 36, and is then reflected twice to pass through the slit 30 on to the photographic plate 11, forming a trace 40b. This trace is displaced from the original trace 40a by a perpendicular distance equal to the error in the workpiece multiplied by the magnification imparted by the lens 36. In another embodiment, the photographic plate is replaced by a screen on which the required profile is drawn, a cursor wire being used in place of the slit 30 to indicate which portion of the workpiece is being traced. Specification 885,508 also is referred to.

Abstract: 952,203. Reciprocating pumps. WEATHERHEAD CO. July 1, 1960 [July 6, 1959], No. 23169/60. Heading F1A. [Also in Division G3] The barrel 50 of a swash plate pump is non- rotatably mounted on a guide member 38 and is axially slidable thereon. Pump pistons 58 are reciprocated in one end of cylinder bores 52 by a swash plate 20 and control suction ports 57; reaction pistons 68 loaded by springs 75 are slidable in the other end of the bores 52 and engage members 69 carrying outlet valves 71 in the end plate 35. The barrel 50 is biased in the direction of the swash plate by the springs 75 and so by early closing of the ports 57 maximum delivery is achieved; the barrel is moved in the opposite direction to reduce delivery by the outlet pressure supplied to a chamber 84 under the control of a valve 90. The valve 90 has a cap 93 (Fig. 4) loaded by a spring 82 and a central member 105 which is adjustable by means of a screw plug 106 so that the position of the valve and the spring loading is adjustable. The valve controls an inlet passage 110 from the pressure outlet 7a, a passage 111 leading to the passage 88 connected to the chamber 84 and a discharge passage 114. The left end of the valve 90 is subjected to the pump outlet pressure and the right end to the pressure in the passage 88 and to the load of the spring 57. Maximum output may be controlled by a hand actuated stop for the barrel 50 (Fig. 10 not shown). The suction ports 57 of the various bores 52 may be axially displaced so that cylinders are progressively put out of action (Fig. 7 not shown). The pistons 68 may part from the members 69 to form auxiliary inlet valves.

Abstract: 956,362. Telephone instruments. SONOTONE CORPORATION. July 4, 1960 [July 6, 1959], No. 23265/60. Heading H4J. An electro-acoustic transducer assembly ineludes a housing enclosing a transducer 21 (Fig. 1) and a vibratory diaphragm 64, the housing having a cover wall 70 (Figs. 4, 5) that defines with the diaphragm 64 an enclosure communicating with the exterior of the assembly through a series of apertures in the cover wall, each aperture comprising a slot 71 defined by the opposite edges of a slit cut in the cover wall, the opposed edges of the cut slit being displaced relative to each other by an amount exceeding the thickness of the wall material, and the width of the slot 71 so formed being less than the thickness of the wall material such that it provides a significant degree of damping to acoustic resonances of the diaphragm 64. The slots 71 are made by cutting a series of slits in a sheet-metal blank, bending the material defining at least one edge of each slit out of the original plane of the blank, and bending the material back towards its original position. Each edge of each slit may be first bent in opposite directions out of the original plane of the blank and subsequently bent back inwardly to define a slot 79 (Figs. 11, 12, not shown). The slots are of width 0.0005 to 0.003 inch. The device is a microphone and transducer 21 is a piezo-electric element coupled to diaphragm 64 by a stirrup 66. The wall 70 may have one or more stiffening ribs 78. The circular rim 74 of wall 70 is secured by cement to a housing 60 and to the periphery of the diaphragm 64. Alternatively, or in addition, rim 74 is retained in position by a flange 68 of an elastomeric casing 69. The dimensions of the slots may be checked by holding the wall 70 in a jig and feeding gas under pressure through the wall 70 while measuring the pressure difference on a gauge connected across the two sides of the wall 70 (Fig. 10, not shown).
Patent GB-233158-A (GB)
Abstract: 233,158. Ollert, G. May 23, 1924. Girders.-To balance the stresses set up in loaded lattice-work structures, extension measuring devices are connected to some of the bars of the structure and on alteration in length of the said bars actuate driving devices which alter the length of other bars of the structure so that the extension measuring devices return to their zero position. As applied to a suspension bridge, a rod a, Figs. 1 and 3, is fixed at its end b to a member c and when displaced relatively to the member c, due to loading or heat rotates the switch lever of a controller k to switch on a motor m, Fig. 2, which alterrs the length of the members t so as to restore the stresses in the member c to their original value, whereupon the switch lever of the controller cuts out the motor m. Wedge, chain or other driving devices may be used instead of that shown in Fig. 2, while the girder may be loaded initially to any desired degree. The devices may be used in cases of overloading due to ground subsidence.
