Abstract: An improved outlet tube device for a urinary drainage bag is disclosed wherein an outlet valve mechanism is contained with a rigid housing fixed securely to the drainage bag, rather than just being clamped to the outlet tubing, and thus cannot become separated from the bag. The outlet valve can be opened only by positive action on the part of the medical care personnel, thereby assuring that urine will be discharged only in a controlled manner. Further, because the valve mechanism does not require that a substantial length of tubing with a freely movable end be used in conjunction with the outlet port, there is no need to engage the free end of the tubing with a keeper. Thus the possibility of the tubing springing back to its straight configuration and flicking residual urine on the attending medical personnel is eliminated. In one embodiment the outlet tube device comprises a pinchcock-type valve which is fixedly mounted to the bag and which is normally operative to clamp off the outlet tube.

Abstract: A fluid collection bag and drain assembly comprises: a container having an interior chamber for collecting fluid. Mounted to the container is a compressible, resilient outlet tube having a passage in fluid communication with the interior chamber of the container. A housing surrounds the outlet tube, and the discharge end of the outlet tube is disposed to discharge fluid through the open lower end of the housing. A lever is pivotably mounted to the housing. A closure member extending from the lever is operative to clamp off the outlet tube when the lever is in a closed position and to permit the outlet tube to open when the lever is in an open position. A cover member is pivotably mounted to the housing and is normally operative to close the open lower end of the housing. The cover member is operatively linked to the lever such that when the lever is opened, the cover member is opened to uncover the open lower end of the housing concurrent with the outlet tube being permitted to open.

Abstract: A strobe lighting unit--and a reflector assembly forming part thereof--include a concave reflector having a predetermined shape, typically including a parabolic cross-section. The reflector is formed in situ as part of an assembly process by pressing a thin precut planar blank of reflective material, preferably an aluminum alloy foil having selected mechanical properties, into a die cavity in the reflector housing with a conforming die plunger to bend the blank into the predetermined shape. During the bending process residual tension forces are induced intentionally into the blank and these forces urge the foil into contact with surfaces defining the die cavity to supportively maintain the reflector in the predetermined shape.

Abstract: A movable lens element in a combined view and rangefinder for use in cameras having a variable focus objective lens is configured in a manner facilitating its reciprocal translation about a determinate path in correspondence with camera focusing.

Abstract: An optical trim mechanism is provided for embodiment in the exposure control system of a photographic camera apparatus wherein the output response of the exposure control system is determined by both the photographic scene light reaching the photographic camera as well as the focused distance from the photographic camera to the subject to be photographed. The trim mechanism provides the photographer with a degree of overriding personal control through which he may simultaneously vary the amount of scene light reaching the exposure control system while at the same time varying the output response of the exposure control system as determined by the focused distance from camera to subject.

Abstract: An electrical switching arrangement is provided for use with a photographic camera having a plurality of electrically responsive operational functions necessary for its proper operation. The switching arrangement includes an actuator member which sequentially actuates two switches, supported by a supporting member, formed as a part of the switching arrangement, in precise timed relationship to each other for automatically providing operational functions to the camera. The arrangement includes mechanisms which provide for precision adjustment of the two switches relative to the actuator member such that proper sequencing and precise actuation occurs at both switches.

Abstract: The subject invention provides reflex photographic apparatus incorporating an operator reflex assembly which is moved during a photographic cycle to convert an optical path from a viewing-focusing mode configuration to an exposure mode configuration. Spring means are utilized to drive the assembly, via a four-bar linkage, from the viewing mode position to an exposure mode position quickly and whilst minimizing elastic rebound at the termination of the movement. Motor means are utilized to return the assembly to the viewing mode position following a photographic exposure. The spring means includes a low-rate torsion spring acting in concert with a tension spring connected between a frame member and an eccentric such that the combined torque operative to drive the operator reflex assembly remains nearly constant.

Abstract: A light attenuating filter is provided for a light responsive exposure control system in order to facilitate calibration of the exposure control system so that the amount of scene light admitted by the exposure control system during an exposure interval will substantially correspond to a particular film speed. The exposure control system is of the type having a light detector wherein the light attenuating filter is movable into intercepting relation with a select portion of the scene light directed toward the light detecting means. The select intercepted portion of the scene light is determined and fixed during the manufacture of the exposure control system in order to provide the requisite output response from the light detecting means to terminate an exposure interval in time to insure that the amount of scene light admitted during the photographic cycle substantially corresponds to the select film speed.
