Abstract: The apparatus for dosing metered amounts of dense pasty pharmaceutical substances and for inserting same into gelatine capsules, comprises an extrusion press which extrudes a layer of substance having a uniform density and a predetermined thickness or height. A hollow punch presenting a cavity is dipped inside said layer for its whole thickness or height, so as to take out of said layer, due to the inherent viscosity of the substance, a predetermined dose of the substance itself. The hollow punch is then positioned above an empty capsule half, and the dose is discharged into the said capsule half by means of an ejecting piston slidably movable at the interior of the hollow punch. The extrusion press comprises two parallel walls, one of which is adjustable so as to vary its distance from the other wall, thus varying the thickness of the layer of substance being extruded.
Abstract: There is disclosed apparatus for aspirating and dispensing a liquid sample which includes a storage cylinder within which is included a freely moving solid cylinder. Attached to the storage cylinder is an aspirating cylinder or needle, which is inserted into the sample. Both the storage cylinder and needle are initially filled with water. Before aspirating the sample, a slight amount of water is removed from the storage cylinder resulting in air being aspirated through the needle. Then, the needle is inserted in the sample and water continues to be removed from the storage cylinder, resulting in the sample being aspirated through the needle. The aspirated sample and water are separated by the previously aspirated air, which creates a bubble in the storage cylinder. This bubble lifts the movable solid cylinder in the storage cylinder as the sample is aspirated.
Abstract: A hypodermic syringe apparatus includes a contact member having an apertured front plate and a hydraulic cylinder reciprocated mounting plate supports a group of hypodermic needles in slidable registry with the front plate openings, which pierce a liquid absorbent web backing the front plate. Each needle is connected by a flexible tube to an adjustable stroke piston pump where inlets are connected to liquid injectable holding receptacles. The pistons are simultaneously actuated by a motor driven drive cam carrying shaft, the motor being controlled by a handle carried switch to rotate the shaft one turn. The shaft carrying cam also controls the flow of liquid to the handle cylinder, and the absorbent pad is connected to a source of antiseptic. A marking pad is carried by the handle front wall to identify the puncture area. Another form of handle includes a flexible band separably encircling the operator's hand for specialized field use.
Abstract: A noncontacting marking apparatus for ejecting, upon receipt of a control signal, a drop of marking liquid for marking purposes. The amount of marking liquid is controllable. A tube couples the ejection point of the marker to a source of vacuum for removing excess liquid.
Abstract: A valve and control system for filling sequentially presented containers with measured charges of semi-solid food product and the like from a feed hopper is provided in which the food product is charged into a product cylinder from the feed hopper through the valve and then discharged into a container through the valve in timed sequence with the reciprocating strokes of a piston in the product cylinder. Means are provided to monitor the discharge stroke of the piston to reverse the valve from the discharge position to the charge position before the discharge stroke of the piston is completed to cause the food product in the product cylinder to be returned to the feed hopper. This results in a dynamic discharge that precludes tailing of the food product at the valve discharge port and maintains the food product in the feed hopper in a homogenized state. The stroke of the piston is adjustable to predetermine the quantity of food product dispensed.
Abstract: The machine dispenses a ready-made milk shake. A freezing chamber has a dispensing valve having porting and a valve element so arranged that flow of the semi-frozen comestible and the flavoring material occurs simultaneously. A beater mixes the two during dispensing. A conduit for the flavoring material has a unique coupling to the valve block and a quick-release coupling intermediate its ends. Upon release of the latter, a manually operable sampling valve may be connected to the conduit to selectively draw a sample of the flavoring. A pump is provided for sucking in a liquid comestible and gas in a preselected proportion and delivering them to the bottom of the freezing chamber. A vent is located in the valve block to vent air from the freezing chamber upon start-up of the machine. The vent has an inlet located at a level so that the liquid and gas volumes in the chamber are about equal to the respective proportions pumped.
Abstract: A panel manufacturing machine adapted to produce panels of building blocks; the machine involving the formation of a horizontal course of blocks in end-to-end relation to each other with mortared head joints between ends of the blocks and with bed mortar on top of the blocks, which course is transferred as a unit to be assembled with other courses of blocks to produce a panel. Further, the machine can progressively sense a modular measurement longitudinally of said course to control the overall length of each course when assembled and mortared together.
