An adapter for a swinging bucket centrifuge rotor includes a slide plate having a retaining lip and a cam surface thereon. Movement of the plate in one direction to a holding position disposes the lip to hold above the rim of a microtube to hold the same in place. Movement in an opposite direction introduces a cam surface between the rim of the tube and a flange on a closure to thereby uncap the s...

A method of forming a sleeve of circular cross-section from a flat plate of predetermined shape is provided by which in a very simple, reliable and cheap manner a sleeve can be manufactured, the shape of which corresponds with a desired shape without an additional pre- or post process. In order to achieve the objects mentioned above a method as mentioned is provided in which the plate is pressed t...

A method and apparatus for forming rolls of compressible materials such as a mineral wool felt, wherein the felt is rolled up in a space defined by a pair of conveyors and a compression roll. The position of at least one of these elements, particularly the compression roll, is varied during the course of winding, according to a preset program and as a function of the length of felt already rolled,...

The invention relates to an X-ray generator inverter comprising two alternately working switches (Q1, Q2), which are preferably transistor switches. Between the center tapping of the transformer (M) provided with center tapping in the primary winding and a point between the switches there is connected a direct-current source (E), which, at each given time together with one of the switches (Q1, Q2)...

Cheese box for housekeeping, which partly serves as a storage box (1, 4 and 5), and partly as a slicing mechanism, where the thickness of the slice can be choosen by one or more activations of a knob (16), and cutting of the slice can be done with the movable lid (1), which also serves as a slicing device with a cutting wire (2) and hooks for transportation (3). Before insertion of the cheese into...

An arrangement for lengthwise sorting of lumber pieces comprises a plurality of elongated driven rollers 2, on which the pieces of lumber can be transported and which are arranged with their axes of rotation essentially parallel to form a lumber compartment 7 between adjoining pairs of rollers. There are elements 10, 11 for slanting the pieces of lumber relative to the rollers 2. Elements 9 for gu...

A continuous flexible collecting device runs over wheels of which is the drive wheel. The device carries the oil upwards, over wheel and at an angle to the vertical, through the oil-remover.

A peat digging unit comprising to digging tools (1, 2) arranged after each other in the units driving direction, of which the rear (2) is designed to run out in front of the front tool in bog producing furrows. The front digging tool (1), e.g. a cutting blade, has a processing element circulating which is designed for achieving enough power to penetrate harder sections of material, such as wood pi...

The cover (1) is for a generator with a vertical shaft and is self-supporting. The cover is so shaped that it covers the generator cavities and/or an existing generator cover. The cover is made of reinforced concrete to damp sound from the generator or its attached equipment. The cover provides effective sound-proofing.

ARound the shaping mandrel (1), a flat casing body (2) is wrapped and sealed to form a casing. After wrapping, the casing edges are sealed. The mandrel comprises a fixed body with an outer surface wholly corresp. to the casing inner surface to be produced. The mandrel has one or more longitudinal tracks (12) in which rods (13) are fitted, part of the length of each having an outer surface which is...

The collector positioned in a bore hole to absorb rock heat for a heat pump system, and for heat carrying medium comprises hoses or pipes (1,2,13) and connecting articulated components (8-11). - It is composed of module units (5), each of which comprises a cylindrical chamber (A), of which one end is open, and the other opposing end has two tubular connections (7). Dependent upon the posiionpositi...

The flow of the first liquid (1) is cooled down (T2-T1 ) and the flow of a second liquid (2) is warmed (T4-T3 ) whilst a heating pump (3) by means of the first liquid (1) is alternately driven vertically downward and the other liquid alternately vertically upward through one of two identical storage systems (A, B), at the same time as the stored liquids (1, 2) in the other storage system (B, A) ar...
