Abstract: A culture bottle assembly has a container divided into two compartments by a flange. A closure and flexible septum seals the container from the outside environment. A frame inside the container is moveable between two positions. In one position the two compartments are sealed from each other, and in the second position fluid communication exists between the compartments. The frame has an elongated member and a skirt. The skirt engages the flange to form a seal. Downward force in the elongated member causes the skirt to flex. Cooperating means create a gap between the skirt and the flange when the skirt flexes. The flexible septum covers the elongated member thereby allowing force to be applied to the elongated member without opening the container. A solid media holder has trays for holding solid media in the upper compartment.

Abstract: The prefabricated creep foundation in accordance with the invention is a building system for the laying of the foundations for a heated building with a beam structure above an enclosed, unventilated creep space. The foundations are constructed from base plates made of concrete, foundation beams made of concrete with internal cellular plastic, and ventilation grids for ventilation. The foundation beams consist of an externally reinforced high concrete slab with thick, cast-on-cellular plastic insulation on the inside. The creep space can be inspected more easily thanks to the considerable height of the foundation beams. The thick cellular plastic insulation on the foundation beams enables surplus heat to be utilized, so that the laying of the foundations can take place at a reduced foundation depth. The foundations can be laid using a crane, and can be adapted to the requirements of the project. The invention also relates to a method and means for the production of elements from which the foundations can be constructed.

Abstract: The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame. To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame. Each lateral caulking element engages with and is fixed to the interior of the related upright. Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate carried by the related upright. The vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat. This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.

Granted: 1994-08-02
Abstract: ABSTRACT          PLASTICIZING AND INJECTING UNIT FOR USE IN AN          INJECTION MOLDING MACHINE         The plasticizing and injecting unit com-prises at least one hydraulic advance-retract actuator that is provided with external screw threads, which are screwed into internal screw threads of a bore formed in a carrier and supply block. Means for locking the advance-retract actuator in the bore in that the interengaging screw threads are wedged against each other comprise a plurality of lock screws, which are parallel to the in-jection axis and disoosed on a circle that surrounds the bore in which the actuator is received. Said screws can be tightened to different degrees so that the carrier and supply block and the advance-retract actuator are biased in mutually opposite senses and any deviations from a co-axial arrangement of the interengaging screw threads can thus arbitrarily be changed in its magnitude and direc-tion. As a result, the stresses which result in the over-all structure from a deviation from a coaxial arrangement can be minimized by a simple manipulation.
