IPC: F16L47/02
Filed: 1989-02-24
Granted: 1992-06-03
Abstract: A method serves for making a heating element which has a heating wire (48) wound as a bifilar spiral (14). Such a heating element may be arranged in a part of plastic, which can be welded to a plastic pipe, it being possible to supply power to the radially outer wire ends (44, 46) of the heating wire (48). The intention is that the method can be carried out with little expenditure and the apparatus required for carrying out the method is to permit the heating element to be made in such a way that it is functionally reliable. It is proposed that the heating wire (48) is placed in a bifilar spiral groove (14) in a surface (6) of an injection mould (2), the windings of the heating wire (48) also being arranged at spacings corresponding to the radial spacing of the individual windings of the spiral groove (14). After closing the injection mould (2), plastic material is introduced into preferably radial connecting grooves (8) between the windings of the spiral groove (14), the plastic material at least partially surrounding the heating wire in the region of the connecting grooves (8).

Abstract: The invention relates to an espagnolette with drivers displaceable as a result of the rotation of the latch or the like and with a follower (6) which is assigned to the latch and which, held in its basic middle position, is pivotable out of this in opposite directions counter to a spring load, the follower (6) being assigned an actuating arm (20) engaging on a slide (38) which is under the effect of a compression spring (37). For the purpose of spatially favourable accommodation of the components bringing the follower (6) into its basic middle position, whilst at the same time ensuring a sufficient spring force, the invention provides a coupling pin (25) placed against the actuating arm (20) by means of the compression spring (37) and located between the actuating arm and an auxiliary slide (30) intersecting the slide (38), the coupling pin (25) clamping the claw-shaped end (23) of the actuating arm (20) against the end face (42) of the slide (38). <IMAGE>

Abstract: In order to generate the test words which are transmitted via a test loop and are monitored at the receiving end to check whether they match the corresponding transmitted test word, a memory (PROM) is read out in which test words of this type are stored which preferably correspond to the test words produced by a pseudo-random number generator. During the monitoring operation, the memory, delayed by the transit time of the test loop, is again read out under the same address as the one used during transmission, in order to supply the test word which is to be compared with the received test word.

Abstract: A method of computerised colour matching for articles where articles are photographed, using a still video camera, against a set of reference colours. The photographs are stored on a diskette (34) which is read on a recorder (54). The compouter (55) compares the set of reference colours against an absolute set of colours and generates a compensation factor which is applied to the photographed colours to produce a corrected photograph. Areas of the corrected photograph may be selected for computer enhancement and a computer generated map may be produced to enable the colour of other articles to be matched to the photographed articles.

Abstract: Process and apparatus for the biological conversion of organic substances into biomass. The organic substances are introduced into a rotatable reaction container, and agitated therein with introduction of fresh air and continuous mixing for a period. Before introduction into the reaction container, the organic substances are finely comminuted and mixed in a preparation apparatus (20) with introduction of fresh air. The preparation can be associated with partial conversion of the material into biomass. The introduction and removal of the prepared material and of the biomass, respectively, into and out of, respectively, the reaction container is controlled depending on its speed of rotation and a temperature condition, which characterises the progress of the conversion reaction, in the reaction container. The preparation apparatus (20) comprises an essentially closed housing (23) with an inlet opening (21) and with a bottom (24) at the base, a mixing and comminuting device (25) in the region of the bottom, a device for introducing fresh air into the interior of the housing (23), a closable outlet opening (22) at a higher level than the bottom (24) and a conveying device (26) to transport the material between the bottom (24) and the outlet opening (22).

Abstract: A valveless, positive displacement metering pump is provided by the invention. Such a pump includes a housing (22), a working chamber (24) within the housing (22), a piston (82) within the working chamber (24), the piston (82) including a duct (86) defined by a portion of its outer surface, one or more inflow ports (96) communicating with the working chamber, one or more outflow ports (96) communicating with the working chamber (24), and a drive cylinder (66) for simultaneously rotating the piston (82) and causing it to move in back and forth strokes within the working chamber (24). The housing (22) is rotatable with respect to the piston (82) to adjust the timing of the fluid communication between the duct (86) and the inflow and outflow ports (96), respectively. Such adjustments in timing allow the flow rate of the pump to be fine tuned, and allow each port (96) to experience a partial suction as well as a partial discharge. It also allows backflow to occur in an inflow line (96) to the pump, thereby cleaning any filters within the inflow line (96) or agitating a suspension from which the inflow line (95) draws fluid. It also permits suction to be applied to an cutflow line (96) at the end of a discharge stroke, thereby preventing hanging drops or strings from forming at the discharge end of the outflow line. In addition, timing adjustement allows the manufacture of relatively inexpensive pumps in which the axes of the drive cylinder (66) and working chamber (24) are maintained in fixed positions relative to each other. A method for adjusting the flow rate of a valveless, positive displacement metering pump is also provided which includes adjusting the phases at which the piston duct (86) communicates with each of the ports (96) of the pump. <IMAGE>
