Abstract: Sulfate-reducing bacteria are detected by preparing a lysate so as to release an enzyme essential to derive energy by reduction of sulfate such as adenosine 5ʹ-phosphosulfate reductase (APS reductase), contacting the lysate with an antibody of the enzyme, and detecting the presence of the reaction product of the enzyme and the antibody. In one aspect, sulfate-reducing bacteria are controlled responsive to such assay. In another aspect, a "test kit" is provided for carrying out the assay.

Abstract: The coloured filters consist of a cured polyamide containing a plastosoluble dye. They can be made by a lithographic process by performing the following treatment cycle: a) deposition onto a substrate (1) of a first layer (3) of a solution of at least one polymer and of at least one plastosoluble dye,  b) deposition of a second layer (5) of photosensitive resin, c) irradiation of certain regions of the second layer (5) of photosensitive resin so as to define the locations of the filters,  d) removal of the photosensitive resin (5), e) removal of the layer of polymer and of dye (3) from the regions of the substrate which are no longer protected, and  f) heating the coated substrate to cure the coloured filters. To obtain a mosaic of coloured filters this treatment cycle is repeated a number of times while employing a different plastosoluble dye in stage a) and defining different filter locations in stages c) to e). <IMAGE>

Abstract: A method of dewatering filter cake in which the cake is supported on a positively driven pervious conveyor belt or filter cloth. The cake is guided about the circumference of a drum, with the drum positively driven at a variable speed of rotation. In the region of the drum, the pervious conveyor belt or filter cloth holds the cake against the periphery of the drum and additional pressing rollers press the filter cloth and cake against the drum. The drum drives the filter cloth in this region through the medium of the filter cake and induces shear effects in the cake. The speed of rotation of the drum is regulated in dependence on the tension existing in the filter cloth.

Abstract: Aluminium-lithium alloys are cast on a twin-roll caster under an inert atmosphere to give a cast slab from 2-7 mm, and preferably 2-4 mm, thick. Alloys may be of the 2000 or 8000 Series. Casting speed may be from 50-200 cm/min and the diameter of the rolls from 20-50 cm. The alloys are more easily cast with less centre-line segregation than are Al-Mg alloys of comparable long melting range. The case slabs are in a suitable form for cold rolling to make sheet.

Abstract: An electrical terminal (2) has two arms which define a receptacle (10) for a pin or post (6). At least one of the arms comprises a web (24) extending to the pin-receiving end (28) of the receptacle (10) and which has sidewalls (30) extending from its marginal side edge portions (26). A slot (34) extends inwardly in the web (24) from the pin-receiving end (28) of the receptacle (10) and divides the web (24) into two sections, each of which consists of one of the sidewalls (30) and the portion of the web extending from the sidewall to the slot (34). The opposed internal surfaces (32) of the sidewalls are spaced apart by a distance less than the width of the pin (6) so that when the pin is inserted, the two sections are each deflected and bear against the pin with contact forces. Each of the sections is elastically deformed by planar deformation of the sections away from each other in the plane of the web (24) and also by torsional deformation. The resultant contact forces exerted on the pin (6) are produced by the two modes of deflection and relatively high contact forces are achieved as a result.

The other end of the universal-joint shaft is connected to a rotatably mounted workpiece carrier (5) to be fastened to the machine table (4), a gear train (7 to 9) between universal-joint shaft and workpiece carrier providing for a certain transmission ratio. When the transmission ratio is 1:2, a two-cornered figure is produced when there is one cutting edge, a square is produced when there are two cutting edges, a hexagon is produced when there are three cutting edges, etc. A triangle is produced when the transmission ratio is 1:3 or 1:1.5 and there is one cutting edge. A pentagon is produced when the transmission ratio is 1:2.5 or 1:1.25 and there is one cutting edge. This series can likewise be continued. A machine tool can be easily reset by this attachment in order to produce, with due regard to the geometric relationships, polygonal workpieces having few spherical surfaces. <IMAGE>

Abstract: A prime mover for motor vehicles comprises a front motive power unit (1) flexibly supported on the body, which unit is rigidly connected to a rear drive unit (3) by a central gradient (6) through which extends a drive shaft (5). The central gradient in the forward area adjoining the motive power unit of low bending stress has at least one longitudinal slit (11) axially limited in its length which is arranged in a vertical longitudinal centre plane (X-X) of the central gradient. The slit produces a reduction in the torsional rigidity whilst at the same time retaining the bending rigidity of the central gradient. In this way the torsion characteristic frequency of the unit is reduced to such an extent that torsional resonance no longer occurs and running vibrations of the drive train are avoided. …<IMAGE>…
