Title: Method and apparatus for vision analysis
IPC: A61B3/024
Filed: 1972-09-15
Abstract: 1405482 Optical testing OCULOMETRICS Inc 15 Sept 1972 [17 Sept 1971] 42915/72 Heading G4H [Also in Division A5] Apparatus for testing the visual field of a subject 21, Fig. 2, under the control of a computer 41, Fig. 1, comprises means 32-36, Fig. 2 (56, Fig. 1) for continuously monitoring the coordinates on a planar test screen 24 of the instantaneous location 23 of the direction of gaze 22 of the subject so as to compensate for eye movements. In the campimetric process described, momentary stationary light spots of selected stimulus value are sequentially displayed on the screen, the spot location and brightness data input to the computer being expressed relative to location 23, and the stimulus value of a spot being controlledly varied in accordance with the response of the subject until the threshold value of stimulus at that location has been determined.  The test is applied to one eye at a time, and a C.R.T. 48 provides the screen and the display. Data is input to the computer by card, tape or typewriter 42 and is fed via registers 43, 46 and D/A converters 44/47 to the C.R.T. control circuits 45 which convert the input data to coordinates fixed on the screen and adjust the brightness values to compensate for changes in the eye-light spot separation caused by eye movement. Co-ordinates 23 (the "fixation point") are monitored by a conventional oculometer, Figs. 14, 15 (not shown), or by an electrooculograph, Figs. 16-18 (not shown): the analogue data from 56 may be fed directly to circuits or may be used by the computer 41. Means are incorporated to halt the test if the fixation point strays too far from the centre of the screen. Further test conditions (e.g. duration of each test spot, time between test stimuli, whether or not to recheck threshold level when this differs significantly from the predicted level) are preset on switches 30 (input 53, Fig. 1). The subject 21 responds to a stimulus on the screen 24 by indicating (by means of a "joystick" 49) the angular sector of the test field where he observed the stimulus (assuming he could see it). This angular position is transmitted in Gray code by an encoder 50 to a register 51 which is sampled by computer 41 and a suitable response (pleasant or unpleasant tone for correct or incorrect response) is provided by a tone generator 52. This process is repeated under the control of the computer program, which uses the response information to generate new brightness levels until the threshold value for the location concerned has been determined, after which a fresh location is chosen. The locations are chosen in a random manner, and may include light spots used for mapping the blind spot boundaries. Fig. 3 shows a general flowchart for the above described process: the individual operations of this chart are described in detail with reference to Figs. 5-8, 10 and 19 (not shown). When the threshold values for all the points used in the test have been determined, a graph plotter or other output device 55 produces a complete visual field plot with isopters (Fig. 12, not shown).

A rubber-metal thrust spring of the kind comprising an annulus of rubber 10 adhered to an inner frusto conical metal core 8 and a correspondingly shaped outer casing 1 is characterized in that the casing is cup-shaped to form a closed cavity 11 between the core 8, the rubber annulus 10, and the base of the casing 1. The cavity 11 is filled with a pressurized gas by means of a filling spigot 4 which has a spring- loaded non-return valve 7 and a pressure-tight screw-cap 5. A threaded hole 9 in the metal core 8 is adapted to receive a load transmitting member. In a modification, Fig. 2 (not shown), the casing (12) is closed at the bottom by a pressure-tight cover (13) which is provided with an inlet spigot (16) for the introduction of a load transmitting medium into a further cavity (15) formed between the annulus (12), the core (14), and the cover (13). The pressure of the gas can be varied to suit the load and the size of the cavity 11 can be altered by filling it e.g. with scrap. In a further modification, Fig. 3 (not shown), load is transmitted by means of a piston (28) which is slidable in a cylindrical core member (25) filled e.g. with oil, water, or a plastics material. Gas can be introduced into the cavity (31) through the threaded hole of a connection stud (33).

[Also in Divisions B6 and F2] A rotary electro-adhesive coupling for a wire printer (see Division B6) comprises an electrostatic clutch rotor 160, Fig. 6, having a peripheral surface formed from a layer 65 of electro-adhesive material, such as a semi-conductive material including rubber, phenolic resin, asbestos and carbon black. The layer 65 which is superimposed on a base of conductive material is connectible to an electrical circuit, which includes the clutch band 62, attached with one end to a print bar 50 and the other to a stationary peg 63. The clutch band 62 is of spring steel and has its under surface in continuous contact with the outer surface of the layer 65. On application of a voltage between the layer and the band an electro-adhesion is obtained causing the band to be mechanically displaced by the rotating rotor 160. The effectiveness of the electro-adhesive attachment is improved by applying a silicone fluid lubricant to the surface of the layer 65. Specification 843,949 is referred to.

Abstract: 1522847 Hydraulic lifting device DOVER CORP 24 Oct 1975 [25 Oct 1974] 43693/75 Heading F1D [Also in Division B8] An hydraulic lifting device comprises a first cylinder 12, and a piston 14, having an axial bore 42, the piston 14 slidably engaging both the first cylinder and a second cylinder 10. Hydraulic fluid introduced into the cylinder 12 from an inlet 36, passes through the bore 42 into the cylinder 10 which moves upwards due to the fluid-pressure, the piston 14 remaining stationary until a spring 28 engages a flange 20 whereupon the piston travels upwards with the cylinder 10 until a flange 22 contacts the upper end of the cylinder 12. Whilst hydraulic fluid is being supplied, entrapped air may be vented through vents 32, 34. Retraction of the piston 14 and cylinder 10 is accomplished by allowing hydraulic fluid to escape through the inlet 36. The lifting device is mounted for movement of a lift installation in which the cylinder 10 forms a rigidly integrated vertical support member of a lifting frame for a lift cage. Support members 46, 48 which are rigidly attached to the cylinder 10 and a follower guide 64, rigidly attached to the piston 14, carry rail guides 50, 52 and 66, which engage rails 58 and may either be of the roller or sliding type. The cylinder 12 is fixedly mounted in a hole formed in a floor 60.

Abstract: 919,595. Purifying salt water by freezing. SCIENTIFIC DESIGN CO. Inc. Dec. 14, 1961 [Dec. 15, 1960], No. 44895/61. Class 29. A process for producing fresh water from salt water by freezing a part of the water in the latter by evaporation of an added liquid refrigerant, separating the ice formed from the brine, and melting the separated ice, is conducted in a number of stages operating at successively lower temperatures and pressures, the separated brine from one stage being the feed to the next succeeding stage. As shown, cold deaerated sea water enters the first stage of a three-stage system through a line 23, and part of its water content is frozen in a crystallizer 11 by the evaporation of a refrigerant such as liquid butane introduced through a line 27. The brine and ice slurry passes to a separator 17 from which brine flows to the second stage via a line 29, the ice being transferred to a meltercondenser 20 where it is melted by heat liberated by the condensation of refrigerant vapour drawn from the crystallizer through a line 281 by a compressor 14. The liquid refrigerant returns to the crystallizer through the line 27, while the melted ice leaves as crude fresh water via lines 26 and 42. The two succeeding stages are the same as the first, except that the freezing pressures and temperatures in the crystallizers are lower for each successive stage. Make up refrigerant may be supplied through lines as at 28a. The crude fresh water may be stripped of refrigerant and also used to pre-cool incoming brine. Approximately equal amounts of fresh water are extracted at each stage, and successive stage freezing temperatures may be 28.3‹, 27.8 ‹, and 27.1 ‹ F. In a modified form of the process, a single melter-condenser serves all three stages, the liquid refrigerant being divided into three equal parts for return to the crystallizers.
