Abstract: A hand held all-visibility (no stethoscope required) blood pressure measuring instrument comprising a manifold, a combination blood pressure and systolic-diastolic points indicating direct reading gauge physically and funtionally connected to the manifold, a squeeze bulb physically and functionally connected to the manifold and forming the hand grip for holding the instrument and having a stiffening member connected to the manifold and extending through the interior of the bulb to prevent bending distortion of the bulb and resultant waver of the gauge, and a short stroke, quick action press type air release valve physically and functionally connected to the manifold in a position where it can be completely operated solely by very short strokes of the thumb of the holding hand (either right or left) while the hand is in a completely normal position and the gauge is in a fully readable position while being held steady and still.

Abstract: A sphygmomanometer in which the gauge in addition to indicating the extent of the systolic and diastolic pressures also indicates when these pressures occur directly adjacent the gauge pressure hand without the use of any stethoscope or electronic medium.

Abstract: A bulk material handling conveyor comprising an overhead conveyor which supports containers in the form of magazines for the material. Each magazine has a filling opening surrounded by a gasket, and a movable closure for the filling opening which in closed position covers the filling opening and coacts with the gasket to tightly seal the magazine against leakage from within and without. A filling spout is located adjacent the path of travel of the magazines and comprises a fixed section and a movable section. The fixed section is suitably supported and the movable section has means for moving it from a position where it is out of the way of the movable closure to a position where it tightly contacts said gasket and covers said filling opening to completely prevent any escape of material and dust during the filling operation. A vent is associated with the filling spout to allow air to escape from the magazine during filling.

Abstract: A material handling conveyor comprising an overhead conveyor which supports containers or magazines for the material. The magazines have top and bottom openings and a closure for each which includes a closure mechanism having a movable lever. The first part of the movement of said lever effects the closing of the magazine and the last part of the movement of said lever clamps the closure down tight on the magazine to provide a leakproof seal. The entire area of the magazine which is in contact with the material being carried is made of an inert substance such as stainless steel or a plastic which is supported by a frame made of a stronger substance which also carries the full weight of the magazine and the material being in the magazine, thereby relieving the inert substance part of the magazine from carrying the load which enables that part to be made of lighter construction.
