Abstract: A caddy for organizing the storage of a plurality of wrench sockets is disclosed herein having a support member with a flat planar plate provided with a plurality of openings for insertably receiving a variety of sockets for storage. The plate openings are arranged in a predetermined order of socket sizes in rows and columns with raised dimensional values adjacent each opening corresponding to a particular socket size. A peripheral flange carried on the plate serves as a stand-off for raising the support member plate above a supporting tool box tray or the like. A magnetic pad or layer may be disposed on the tray below the plate for magnetically attracting the sockets for releasably holding the sockets in place. Each opening includes a pliable tab intended to releasably grip a respective socket in the opening.

Abstract: A tonometer for measuring the intra-ocular pressure of an eye in which a pulse of fluid is projected towards the cornea of the eye to distort the corneal surface by the pressure of the pulse, the distortion in the corneal surface being detected by a change in the reflection of light directed onto the cornea. A constant volume chamber forms part of the fluid delivery system, with an inlet by which fluid under pressure can be supplied to the chamber when a fluid pulse is required. A lens assembly is fixed in the chamber wall for directing light toward an eye under test and a tube extends coaxially through the lens assembly to protrude internally into the chamber, where it is closed off at the end but includes a plurality of apertures in the internally protruding wall section to permit the controlled passage of fluid from the chamber into the tube.

Abstract: A tie-down device is disclosed herein having a movable car slidably carried on a stationary track which includes a spring biased vertically movable latch on the car operable to be insertably received into a selected one of a plurality of openings on said track for releasably retaining the car in a critical location on the track. The car further includes an attachment arrangement such as a tongue-in-groove construction for mounting on the track and a securement loop universally carried on a car flange for attachment to a tie-down line or cord.

Abstract: A tonometer is described for measuring the intra-ocular pressure of an eye in which a pulse of fluid is projected towards the cornea of the eye to distort the corneal surface by the pressure of the pulse, the distortion in the corneal surface being detected by a change in the reflection of light directed onto the cornea. A fluid delivery system (36, 44, 48) leads to an outlet through which the fluid pulse is applied to the cornea, and a branch (54) leads to a pressure measuring chamber (52), containing a transducer (170) which produces an electrical signal whose value depends on the pressure in the branch. A flow restrictor is removably fitted in the branch (54) and signal processing means (176, 178, 180) (the gain and rise time of which are adjustable by (182) or (186)), is supplied with the output from the transducer. Adjustment of 182, and 186 enable the electrical signal output of the processing means to be adjusted, for calibration.

Abstract: An apparatus for automatically determining various stresses measured by a rectangular strain gage rosette. The apparatus receives signals from the rosette and provides signals representative of the maximum principal stress, the minimum principal stress and the maximum shear stress, the peak maximum principal stress, the minimum principal stress at the instant when the maximum principal stress is peaking, and the peak value of the shear stress. A first analog signal processor provides stress signals representative of the maximum principal stress, minimum principal stress and maximum shear stress for each instantaneous input signal amplitude from each arm of the strain gauge rosette, and a second signal processor receives the stress signals and provides output signals representative of the peak maximum principal stress, minimum principal stress at the instant of peak maximum principal stress, and peak maximum shear stress.

Abstract: A system for monitoring the integrity of a cable, for example a cable for towing a variable depth sonar body through the ocean, is described. Such a cable comprises a core of electrical wires surrounded by load bearing wires which are secured to the sonar body through a terminator. For various reasons cracks can appear in the load bearing wires and in extreme cases one or more of the wires may break. The monitoring system includes a transducer located near the terminator where the wires are most likely to crack or break and acoustic emissions caused by the incidence of cracks or breaks are picked up by the transducer. The resulting electrical signals are amplified and passed up the electrical core of the cable to the towing vessel where they are processed. Novel aspects of the system are the water coupling between the location of the cracks or breaks and the transducer and special processing circuitry which enables breaks, cracks and electrical noise to be distinguished from each other.

Abstract: Apparatus useful in repair of a termination of an outer cover of an armoured cable. The outer cover comprises a number of wires and the termination is effected by location of the wires between an inner body within the outer cover and an outer body outside the outer cover. The apparatus has a first block to surround the cable and grip the inner body. A second block surrounds the cable adjacent the first block. The second block abuts an end of the outer body. The two blocks can be forced apart to separate the inner and outer bodies and thus open the termination. A wire separator retains the wires of the outer cover separate after the forcing open of the termination. The apparatus is useful aboard ship whereas previously cables could only be reterminated in part.
