Abstract: A method of producing stereoscopic film from standard 35 mm film is described in which the standard 35 mm is longitudinally cut in half. Selected sprocket holes in each half are enlarged to provide a series of locating holes at regular intervals along the film. Each locating hole enables a corresponding pair of stereoscopic film frames on the film to be located in a viewing position. Also described is a viewer for viewing the stereoscopic films. The viewer incorporates a locating finger which engages each locating hole in turn to locate and hold the film steady while viewing. The viewer includes a reciprocating drive means for driving the film. The locating finger is withdrawn from a locating hole when the drive means performs its forward stroke and the forward stroke is limited when the finger engages the next hole. The finger remains engaged with the next locating hole during the return stroke of the drive means thereby preventing any inadvertant movement of the film during the return stroke.

Abstract: A foot support is herein described as having a base member for vertically supporting a patient's lower leg and foot above the level of the bed upon which the patient is lying. A sling is attached to the base to extend generally horizontally with respect thereto and to engage the underside of the patient's foot to prevent the base member from moving up the patient's leg.In one form of the invention, the base member may have a horizontally extending opening for receiving the patient's lower leg. The opening may be sized to prevent the patient from horizontally withdrawing his leg and foot and a slot may be formed in the base member to extend from the periphery thereof to the opening. The patient may insert his lower leg and foot into the supported position within the opening by moving the lower leg portion transversely through the slot and into the base member opening. Multiple hook-like material fasteners may be used to secure the slot while the leg is being supported within the opening of the base member.

Abstract: An apparatus is herein described for directly massaging a human heart which apparatus can be left in place at the end of an operation and be removed at a later date. The apparatus generally includes a cup-like inflatable bladder formed to surround the heart and to massage the heart in a predetermined manner in response to the creation of pressure pulses within the bladder. A basket-like support is provided for disposing the bladder in an operational posture around a heart during the heart massaging process. In one form, the support is inflatable into a rigid structure and deflatable to a generally pliable, non-rigid condition to permit its removal through a small opening or a tube. In addition to the bladder and basket-like support means, a suction tube communicates with the annular space defined between the heart and the bladder so as to insure a positive contact between the bladder and the heart.

Abstract: A bearing is herein described having an annular housing defining a bore. A plurality of arcuate bearing shoes are spaced within the housing bore in such an array to define a cylindrical opening for axially receiving a rotatable shaft. The shoe members are disposed in a generally free floating posture.Mechanical stops are provided for maintaining the shoes in a generally operational disposition while the shoes are still in a free floating condition. A spherical male and female combination of inserts are provided with their operational axis generally along a radius of the bore of the housing and located at the approximate center of the arc defined by each shoe. The male and female spherical members are then operable to provide universal movement about a point approximately at the center of the arc of each shoe so that each shoe is infinitely flexible to adapt to shaft variations.

Abstract: An improved sleeve arrangement is herein provided for protecting splices in pipe-type cables. The sleeve is formed with a diameter which is slightly larger than the overall diameter of the spliced cables and is tapered at the ends to correspond to the tapering of the spliced cables.The sleeve may be made in two halves and the end flanges thereof bolted and gasketed. Alternatively, the sleeve may be welded. In one form of the invention, a cage like support is provided within a main casing having a diameter somewhat larger than the diameter of the spliced cables and tapering at the ends thereof to properly support a splice and at the same time to permit free longitudinal movement. The cage may comprise a series of metal strips welded at each end to a flange which may be bolted to the end flange to which the outer casing is welded.

Abstract: A device for angularly centering a member having an annular toothed formation, for example an electric motor commutator prior to mounting the commutator on a rotor shaft, comprises a centering bracket located in the path of movement of the member. The bracket has, at its upstream end, a ramp, followed by two laterally spaced centering profiles. If a tooth of the member engages the ramp, the bracket is resiliently deflected and the tooth thereafter engages one of the centering profiles. Alternatively, the tooth will directly engage the other of the centering profiles. When the member has been centered by either one of the two profiles, it is held in its centered position within a grooved seat to enable further operations to take place.
