Abstract: An efficient packing element for exchange columns is made up of a plurality of preformed vertical sheets (12), each having a plurality of elongated inclined troughs (18) including converging embossed sidewalls, valleys (V), and ridges (R) extending between upper inlet edges (20) and lower outlet drip edges (22) and projecting alternately outwardly from one side and then the opposite side of the median plane of each sheet. Projecting from the converging sidewalls of the troughs are a plurality of hollow protuberances (30) such as, produced by embossing with perforated peaks including small openings (32) surrounded by edges of the wall about the peaks. The sheets are arranged so that the inclined rows of the embossed troughs in adjacent sheets are oppositely inclined and in criss-crossing relation to the inclined rows of the adjacent sheet of the packing element causing frequent changes in direction of liquid flow and whereby both embossed sides (14, 16) of each sheet are more easily and uniformly wetted by the frequently diverted liquid flowing downwardly over the surfaces thereof.

Abstract: A method for detecting the MB isoenzyme of creatine kinase in a biological fluid characterised in that it comprises:
     (a) forming a mixture of (i) a sample of the biological fluid, (ii) an antibody to the B monomer of creatine kinase, the said antibody being bound to a solid support, and (iii) a labelled, monoclonal antibody to the MB isoenzyme of creatine kinase;   (b) incubating the mixture;   (c) separating the solid support from the mixture; and   (d) detecting the amount of label associated with the solid support is disclosed.   
     A monoclonal antibody characterised in that it is produced by a murine-derived hybrid cell line, the said antibody being capable of specifically binding to at least one antigenic determinant of the MB isoenzyme of human creatine kinase and being of the IgG1 type is also disclosed. 
     A murine-derived hybrid cell line ATCC HB 9389 or HB 9388 and mutants thereof are further disclosed. 
     More particularly, a single incubation CKMB assay is provided which employs an anti-CKB capture antibody bound to magnetic particles and an anti-CKMB tracer antibody labelled with an acridinium ester. The assay achieves a minimal detectable dose of at least 1 mg/l CKMB for incubations as short as 10 minutes at room temperature, and is not subject to interference due to the presence of macro-CK-1 or high levels of CKMM and CKBB in serum samples. In accordance with certain preferred embodiments of the invention, the anti-CKMB   tracer antibody is a mouse monoclonal antibody of the IgG1 type. 
     The present assay is faster, simpler to use and less subject to interference than prior art assays and yet maintains the sensitivity thereof.

Abstract: A hot melt adhesive applicator operable at a number of selected temperatures having a portion of the circuitry for control of the applicator temperature at a point remote from the applicator body. The remotely located circuitry employs a differential amplifier 39 and a zero crossing detector 38 for controlling the operation of a triac 41 which, when turned on, increases the temperature at the applicator. The differential amplifier 39 is protected by a clamping circuit 66-68 from receiving a signal, when a temperature setting is changed from a high to a low setting, that would otherwise cause the differential amplifier 39 to provide an output required for turning on the triac 41 which would cause a run away condition to exist.

Abstract: The dust filter bag comprises a filter paper outer layer and a fine fibre non-woven fabric, each having characteristic specific properties. The fine fibre non-woven fabric can, if required, be reinforced by a supporting element. The combination of appropriate filter materials for the filter paper outer layer, the fine fibre non-woven fabric and the supporting element leads to high degrees of removal of fine dusts, and, at the same time, low air resistance and a low tendency to filter clogging. The multilayered filter bags can, according to the individual design, be manufactured on corresponding bag machines. The outstanding filtration properties allow the dust filter bags to be used for the removal of particles greater than or equal to 0.1  mu m in vacuum cleaners of the most diverse types, and also in the removal of toner by suction in copiers. Furthermore, the combination of the filter materials described in the form of flat filters, pleated filters, belt filters and roll filters is suitable for use in clean room technology, e.g. in semiconductor manufacture, film manufacture or in the hospital sector.

Abstract: A continuous separator, for separating liquid from gas, comprises a cylindrical chamber (16) into which the liquid/gas mixture enters at 12 and is directed tangentially around the cylindrical interior wall of the chamber (16). Two conical mesh members (18,20) are situated inside the chamber. The gas in the mixture is partially separated out as the mixture swirls around the wall of the chamber. Any remaining gas-containing droplets of fluid are caught on the meshes of one or other of the two conical members (18,20), and the gas escapes from such droplets. The liquid component therefore falls through to an outlet (24) and the gas rises to an outlet (22).

Abstract: In an rf coil of a magnetic resonance apparatus steps are taken to optimise a uniform rf measuring field. To this end, axially extending current conductors are provided with means for generating a non-constant effective current intensity (56) in current paths (54) extending across a cylindrical surface so as to be parallel with a symmetry axis of the coil. This can be realised by deflecting axial conductors away from the cylindrical surface, by partly shielding them, by adding auxiliary coils to be individually controlled, or by connecting L-C circuits across the current conductors.
