Abstract: A drip infusion system is disclosed in which a pulling mechanism is connected to a needle for automatically pulling the needle from the vein of a patient. The pulling mechanism is actuated to pull the needle from the vein responsive to the amount of solution in a drip source mounted on a stand.

Abstract: A collapsible container comprises side panels which are interconnected at their side edges by end panels. The side and end panels form a container space which can be positioned on top of a pallet. A bottom length flap extends from a lower edge of each side panel. One of the length flaps is intended to be secured to the top surface of a pallet. The other length flap is flanked by bottom width flaps which are each connected to a lower edge of one of the end panels. Each panel and flap is interconnected along a score line. Each end panel has a central vertical score line between score lines connecting the end panel to the adjacent side panels which extends from its upper edge down through a connected bottom width flap so as to divide each width flap into halves. One half of each width flap also includes a diagonal score line which extends from the adjacent side panel down to meet with the central score line dividing the width panel in half.

Abstract: A multiple container package includes four containers which each have a polyhedral body portion with an elongated neck portion. The body portion of each container has lateral polygonal side walls, spaced apart front and rear walls a top shoulder and bottom wall. A recess which is perpendicular to the neck extends either in the front wall or the rear wall and receives the neck of an adjacent container. Four containers can be mated together to form a package having a polyhedron volume with the volume being substantially filled by the containers.

Abstract: An improved push/turn tap and drain spout fitment for a multi-wall fiberboard container with a plastic retainer for retaining bulk flowable materials including a polygonal flange mounted within a similarly shaped opening in the fiberboard. A valve tube extendable through a spout assembly. The valve tube includes prongs for engaging a bung which is threadably connected to the spout assembly to seal an opening in the plastic retainer. The valve tube, though sealingly coupled to the spout assembly, can be moveably manipulated from the outside of the container to cause the bung to become disengaged from the spout assembly.

Abstract: A mixing apparatus is composed of a vertical cylindrical shell having a mixing space divided into multiple pass annular mixing chambers by a concentrically arranged cylindrical shroud, and tubes. An outermost chamber houses a jet nozzle which provides high velocity motive jet tangentially into the annular outer riser chamber, an injector and specially constructed baffles to cause an ascending generally helical mixing to occur. Provisions are made for recirculating part of the mixed fluids from an intermediate downcomer passage to the outer riser chamber.

Abstract: In the spaced between a plurality of airplanes that are supported by a rotatable bottom wall of an airplane hangar, lifting platforms are mounted on pivoting levers. The lifting platforms are adapted to support further airplanes on an elevated level. The lifting platforms can be lowered, thereby moving translationally in a radial outward direction. A single hydraulic cylinder arrangement is mounted in a sector containing a movable door section of the hangar peripheral wall. Each lifting platform, upon rotation into that sector, is automatically coupled to the cylinder arrangement for swinging the lifting platform downwards onto the level of the rotatable bottom wall. The lifting platform, after having been raised again, is automatically disengaged from the cylinder arrangement when it leaves that sector.

Abstract: A shedding device for moving the shedding rods of a circular weaving machine includes a drive shaft which rotates a cam. The cam has a cam groove which lies in a horizontal plane and receives a plurality of cam follower supports. The supports are pivotally mounted near their center to a cantilever arm which is rotatably mounted about a vertical axis at a location spaced from the drive shaft. The cantilever arms hold the supports at correct angular positions with respect to the cam paths. Vertical swinging and pivoting of the follower supports are transmitted through horizontally moving control rods through cranks which convert the horizontal movement to vertical movement. Clamps are connected to the shedding rods and links connect the clamps to the cranks. A single follower can service a pair of connecting rods which in turn service a pair of shedding rods to save space around the cam.

Abstract: A mateable bottle having a hollow L-shaped body is disclosed which has a neck portion formed as a neck rib in an inner front wall surface of the body. The neck terminates in a stub spout which has a large diameter opening, opening into the interior of the hollow body. A concave recess, provided in an outer front wall surface, is shaped to receive a neck rib of a mated container. Outer surfaces of two mated bottles are provided with planar and perpendicular surfaces so that a rectangular solid is formed when the two bottles are mated to each other.

Abstract: At a base of a vise a U-shaped tie element is floatingly mounted in such way that a front leg portion thereof abuts aginst the rear inner face of a stationary clamping jaw. The area of contact between the front leg portion and the clamping jaw comprises the combination of a convex nose at the one part and a planar face at the other part. The tie element is supported by resilient means which are separated from the contact area. Thereby the tie element is self-adjusting and a uniform contact is gained along the whole width of the tie element. During clamping the front leg portion is pivoted with respect to the base section of the tie element, however, thanks to a rolling line contact at the stationary clamping jaw no forces are transmitted which would angularly displace the stationary clamping jaw.

Abstract: A bathtub insert for handicapped persons comprises a bottom frame, a seat plate, two pairs of scissor arms therebetween and a hose fillable with water in order to elevate the seat plate. A flexible cover sheet closes the front end of the bathtub insert between the seat plate and the bottom frame. One end of the cover sheet is fastened at a winding tube and a torsional spring therein holds the cover sheet tightly tensioned even in the lowermost position of the seat plate. The cover sheet at the same time avoids that handicapped persons can be injured by jamming their arms and legs and holds the bathtub insert in a flat-package transportable position.

Abstract: A carrier and a head having fastened thereon a cutting place are connected with one another exclusively by a form-fit coupling. A first contact surface of the head grips under the carrier. A second contact surface of the head above the first surface grips behind an abutment of the carrier and a third contact surface of the head arranged between the first and second contact surfaces thereof serves for transmission of the cutting load.
