Abstract: 925,066. Sight-testing apparatus. A. J. FRIEDMANN. Jan. 18, 1962 [Feb. 1, 1961], No. 1932/62. Class 97 (1). For testing the field of vision, a housing has means for accommodating a perforated screen means and a light source for momentarily illuminating the perforations, means being provided for changing the position or pattern of perforations and for identifying the pattern in use at any instant. As shown in Fig. 1, the housing 1 contains an electronic flash tube 3 for illuminating perforations in a screen 5, which is slidably inserted in guides 1a and has a central pivot 7 on which a perforated shutter 6 is rotatable between angular positions defined by a spring 9 and arcuate detent 8. For each angular position of the shutter 6, a different group of perforations are lit up by operating the flash tube 3. By using a scale 11 and index 10 the blind spots in the patient's field of vision can be plotted; scale 11 may indicate not only which perforation group is exposed but also the number of perforations in that group. Instead of using an electronic flash tube, the source may be flickering or continuous, a shutter being interposed in the light path to the screen in the latter case. In a modification, Fig. 5, a perforated circular screen 17 is rotatable and has rotatably secured thereto at 7 a shutter 6 which is also perforated. The scale and index 11, 10 are again provided and, in addition, there is an index mark 41 co-operating with a scale 42 to indicate the angular position of screen 17. This modified instrument allows additional tests to be performed using the same group of perforations at different angular orientations. In other forms, the rotatable and circular screen is provided with a series of perforations along one radius only and the shutter has an arcuate set of holes or an arcuate slit so that only one perforation is exposed at a time. In yet another modification, Fig. 9, a number of perforated cards 43 are locatable in the guides la, each card having a group of perforations 45 and a pattern identifying mark 46.

Title: Wellbore circulating valve
IPC: E21B49/00
Filed: 1974-01-18
Abstract: 1437761 Wells &c HALLIBURTON CO 18 Jan 1974 02535/74 Heading E1F [Also in Division F2] A well bore circulating valve 1, for incorporation in a test string including well testing instruments and tools such as a pressure recorder, a formation sampler, hydraulic jar and one or more packers, comprises a tubular housing, a normally closed valve in the wall of the housing, the valve, when open and in a well bore, being arranged to provide a communication between the interior of the housing and the well bore, and means for opening the valve which is responsive to changes in pressure in fluid in the well bore for preventing opening of the valve until after at least a predetermined minimum of pressure changes has occured and then effecting opening of the valve. As described the valve consists of a port 31 (Fig. 1a) in housing 3 which is normally closed by a tubular skirt 21 engaging seals 34, 43. The skirt 21 is raised to open the valve by a ratchet mechanism (Fig. 1b) including a tube 2 having latch plates 24 urged inwardly towards a pull mandrel 5 by garter springs 28. The latch plates 24 and pull mandrel 5 are formed with ratchet teeth so that by reciprocating pull mandrel 5 the skirt 21 is progressively raised. The pull mandrel 5 is connected by members 51, 8 12 and 14 to a piston 13 (Figs. 1d, e) having a face 19 in chamber 46 which is in communication with the well bore fluids through port 45. Thus by increasing the pressure of the well bore fluid the piston 13 and hence the pull mandrel 5 is raised. When the pressure of the well bore fluid is decreased the piston is lowered by the action of an inert gas and/or a spring (not shown) in closed chamber 37. Member 12 (Fig. 1d) is formed with a piston 49 having a restricted orifice 53 and which moves in a closed chamber 48 containing oil to act as a damper during upward movement of the piston 13. A by-pass passage 57 and check valve 56 allows free downward movement of piston 13. Thus by alternately increasing and decreasing the pressure of the fluid in the well bore, the piston 13 and hence pull mandrel 5 are reciprocated and skirt 21 is progressively raised to open the valve.

In the arrangement shown in Fig. 1, the upper ends of supports 12, 13 are connected to levers 8 or 9 which are associated with torsion bars 5 or 7, the bars 5 in one construction being directly mounted on the vehicle frame, and the bars 7 in the other construction being carried by brackets 6. Springs 16 acting upon a lug on the axle casing 1 limit the tilting movement. In the modification shown in Fig. 2, the uprights 19, 20 are themselves made of a resilient nature bv having springs 23, 24 incorporated in their structure, and are ball-jointed at their upper ends 1.7, 18 and lower ends 21, 22. Each lower joint preferably comprises a deformable rubber pad 32, Fig. 3, interposed between partspherical surfaces 30, 31 on the axle casing and upright respectively. The springs 16 may be replaced by or co-operate with other springs located near the roof and acting upon an extension of a vertical frame secured to the axle casing. In another construction, Fig. 9, longitudinally disposed bar springs 73-76 function both to effect the vertical suspension of the vehicle body and also to resist lateral canting, additional springs 83 being effective only for the latter purpose. The vertical supports 68 are connected with the torsion bars by levers 71, 72, while the springs 83, 83<1> are associated with two transverse interconnected pivoted levers 82, 82<1>. In ordinary running or loading, the supports 68, 68<1> are displaced equally, the bars 73-76 are stressed, but the springs 83, 83<1> are inactive ; but in negotiating a curve or if the vehicle is unevenly loaded, the supports 68, 68<1> are unequally displaced and the springs 83, 83<1> become effective. A torsion bar may replace the links 82, 821 and springs 83, 83<1>. In still further constructions, means are provided for manually or automatically adjusting the lengths of the uprights, e.g. by combining therewith pistons and cylinders to which the admission of fluid is controlled by means of a centrifugal penduluin.
