Human monoclonal antibody compositions, human-human monoclonal hybridoma cells, human myeloma cells, human antibody genes and their uses. Human myeloma cells are developed for fusing with immunized lymphoid cells to provide stable human-human hybridoma strains producing complete monoclonal antibodies for a predefined antigen. From a myeloma cell line, rapidly growing 8-azaguanine resistant HAT sensitive cells are selected. The selected myeloma cells are crossed with immunized lymphoid cells and the resulting cell mixture grown under controlled selective conditions. After expansion of the desired hybridoma cells, the monoclonal antibodies may be harvested. The hybridomas serve as a source for messenger RNA for light and heavy chains which may be used for production of light and heavy chain immunoglobulin proteins through hybrid DNA techniques.

A conveyor belt, which is adapted in endless condition to follow through part of its length a path comprising a number of superposed, helically extending turns, comprises link means which are articulated with one another and are relatively adjustable and comprise a bottom part and spacing members arranged at the longitudinal edges of said bottom part and constituting the two sides of the belt, said spacing members being adapted with their upper edge portions to bear against the lower edge portions of the overlying turn of the conveyor belt in order to permit this to carry the underlying belt turn, at least part of the spacing members being adapted with their upper edge portions to engage shoulders at the lower edge portions of the spacing members of the overlying turn of the conveyor belt so as to prevent lateral displacement of the belt turns. The spacing members are through part of their length fixedly connected to the longitudinal edges of the bottom part while the remaining part is movable relative to the bottom part and provided with a flange which is inclined downwards in inward direction, said flanges constituting the shoulders with which the upper edge portions of the spacing members are adapted to engage in order to prevent lateral displacement of the belt turns.

The invention relates to an apparatus for marshalling objects into groups on a single, driven conveyor. The conveyor has two end rollers and at least one deflector roller positioned at the lower part of the conveyor. The apparatus also includes an end stop positioned at the one end roller of the conveyor as well as a stop plate disposed to move up and down, at 90° in relation to the conveyor. The conveyor further has a deflection point placed at the upper part of the conveyor. The conveyor is disposed to be slanted downwards from this deflection point in that the end roller is moved downwards.

A buffer conveyor (12) for conveying conformable work products (66) includes a collapsible conveyor belt (13) having an infeed section (14), a collapsible intermediate section (16) and an outfeed section (18). The infeed section (14) may be driven at a non-continuous speed, and the outfeed section may also be driven at a uniform, or non-continuous, speed, but the average speed of both the infeed and outfeed sections is the same. The intermediate section of the conveyor is driven at a non-uniform speed that is slower than, but proportional to, the speed of the infeed section.

A vacuum cleaner device has a nozzle which, via a pivotal connection, is connectable to a lower end of a vacuum cleaner pipe which, at its upper end via a vacuum cleaner hose is connectable to a vacuum cleaner. The vacuum cleaner pipe has inner and outer parts which are longitudinally displaceable in relation to one another, and a joint whose pivot axis is parallel with the pivot axis of the connection. The joint of the vacuum cleaner pipe is disposed on the inner section and, for locking of the joint, is insertable in the outer section.

A grille and bonnet assembly is mounted at the forward end of an automotive vehicle. The bonnet is formed with a leading edge and a trailing edge with the leading edge positioned above or at an upper edge of the grille during normal operation of the automotive vehicle when the bonnet is closed. The grille and bonnet are designed with corresponding inclined surfaces that are located relative to each other such that a force greater than a predetermined value transmitted from the bonnet to the grille forces at least the upper part of the grille to move forwardly so as to allow the bonnet to move downwardly. Such yielding movement of the grille and bonnet can reduce injuries in the event of an impact between a pedestrian and the bonnet of the automotive vehicle.

An endless conveyor belt for an air conditioning plant, in which the conveyor belt extends helically along part of its length, comprising transverse rods (4) and lateral elements (3). The conveyor belt is characterized in that the lateral elements (3) are connected in pairs to only two rods (4), which are fixedly connected to said lateral elements (3) and form, with these, a link means (2), and adjoining link means (2) are articulated to each other by a coupling element (5) arranged therebetween and connected to neighboring rods (4) of the adjoining link means (2).

In a multi-carrier system employing OFDM, for example DMT, an adaptive channel equalizer is normally used, operating in the frequency domain. The sampling clock is controlled so that the time delay between the transmitter and the receiver is effectively eliminated. If the information used to control the sampling clock is received from the equalized data stream, it will introduce an ambiguity between the operation of the channel equalizer and the mechanism used to control the sampling clock. Operation of the equalizer can mask an increasing time difference, between transmitter and receiver, which the sample clock controller should be tracking. The present invention eliminates the ambiguities in the operation of the equalizer and sample clock controller by preventing the equalizer accepting time differences which should be corrected by operation of the sample clock controller.

A method and a device for forming at least a first pattern on a substrate (6,28), which is coated with a layer (5) on at least a first planar surface, are described. According to the method, a first pressing means (27) is arranged with a first structure (32) that defines the pattern, and the substrate (28) is arranged so that the first pressing means (27) is separated from the substrate (28) and so that the first pressing means (27) and the substrate (28) are unable to move transversely of the common center line (50) but are able to move freely in a direction along the center line (50). Subsequently, the first pressing means (27) is contacted with the substrate (28) while maintaining the common center line, and a pressure is applied to the substrate (28) and the first pressing means (27) to form said at least one pattern in the layer (30)
