Abstract: In a process for post-insulating a bend of a thermally insulated pipeline consisting of an inner pipe, preferably of steel, which carries the medium, a jacket pipe of plastic which concentrically surrounds the inner pipe at a distance and a thermal insulation layer of foam, preferably polyurethane, arranged between the inner pipe and the jacket pipe, first of all the pipeline sections extending at an angle to one another are welded together with the interposition of a pipe bend. A mould lying on the ends of the pipelines is placed on over the connecting point and the annular space between the mould and the pipe bend is foamed using a polyurethane in-situ foam. As the mould, a tubular plastics moulding is used which has a longitudinal slit and is pushed over the connecting point. The welding of the longitudinal seam and the circumferential seams is carried out by means of electrically heatable heater bands.

Abstract: A composite die-casting operation, which is exemplified by reference to production of a parabolic aerial (1). A parabolic metal plate (2) is placed between a movable die member (5a) and a stationary die member (5b) in a die-casting machine (4), the die members having a pressure face (6) and a counter pressure face (7), respectively, which are complementary to the final shape of plate member (2). Members (5a, 5b) are moved towards each other to hold plate member (2) and rear structure (3) is cast on to the rear side of plate member (2) and with a shape corresponding to recesses (7a) in counter pressure face (7). By the aid of perforations (2a) in plate member (2), and recesses (6a) in member (5a) the casting metal is made to flow into said recesses fixing said rear structure (3) to plate member (2). The plate member (2) may initially be a planar disk which is bent to dished shape between the die members and also has the necessary perforations punched therein. <IMAGE>

Abstract: A device is provided for determining the presence of an antigen which comprises a trapping zone, which contains material capable of capturing free flowing enzyme linked antibodies, but not antibodies bound to a transport particle which flows freely through the trapping zone into the substrate zone, and a substrate zone which contains material capable of reacting with enzyme-linked antibodies to produce a reaction which indicates the presence of antibodies. A method of determining the presence of an antigen is provided wherein a sample is mixed with two classes of antibodies which are specific for the antigen being tested for, but which react with different antigen domains, wherein the mixture consists of class one antibodies bound to a transport particle which flows freely through the trapping zone and class two enzyme-linked antibodies which are incapable, unless bound to the transport particles, of flowing freely through the trapping zone. In the presence of the antigen being tested for, both classes of antibodies bind to the antigen and flow through the trapping zone into the substrate zone, wherein a reaction takes place to indicate the presence of the antigen.

Abstract: The present invention relates to a receiver and transmitter arrangement for a price information system which includes a plurality of price information units in a shop or store, for instance. Each price information unit includes a loop (20) for receiving a signal (f1) from the control unit. When there is no communication with the price information unit, a voltage-controlled oscillator (50) is controlled by an incorporated crystal (46) via a phase locked loop. When communication is effected with the price information units, the voltage-controlled oscillator (50) is controlled in a manner such that the frequency and phase position of the oscillators in the control unit and the price information unit will coincide. This is achieved by activating a phase comparator (58) (with switch 60) which then receives the following input signals: a real value signal (f6) from the voltage-controlled oscillator (50), and two control value signals [(f3a), (f4a)] obtained by passing the signal (f) through two filter and demodulator circuits (30) and (32) and two comparators (34) and (36). The output signal obtained from the voltage-controlled oscillator (50) is passed directly to the filter and demodulator circuit (32) and indirectly to the filter and demodulator circuit (30), via a phase shift circuit (42).

Abstract: Arrangement in a heat exchanger, for example a retarder oil cooler, constructed from plates with alternating cooling water and oil ducts between them. The plates surrounding the cooling water ducts are provided with converging inward bends in the form of nipples, which are intended to keep the said plates at a distance from one another. Between the plates surrounding the oil ducts there is a so-called turbulator, which on the one hand serves to increase the surface and on the other is designed to make the flow turbulent. The arrangement is characterized in that the oil ducts situated outermost in the cooler each comprise elements designed to reduce the flow through these compared to the flow in other oil ducts. An improved thermal equilibrium is thereby achieved in the outermost ducts, which gives a reduced risk of thermal fatigue, especially in the inward bends converging in the cooling water ducts in the form of nipples. The service life of the heat exchanger is thereby prolonged.
