Abstract: ABSTRACT OF THE DISCLOSURE:           A radiator having parallel flat tubes con-nected to header pipes for feed and return flow, each flat tube having two connection bores near the front end.  To pressure weld the radiator, a U-shaped support part, having two bent ends-arranged coaxially with the two connection bores, is inserted into each flat tube. These ends prevent the flat tube from being pressed inwardly during pressure welding.  The portion of the support part extending parallel with the end edge of the flat tube is welded to the tube end edge, so that the support part simultaneously also forms the end closure wall of the flat tube.

Abstract: ABSTRACT OF THE DISCLOSURE        An eddy current flaw detector particularly for use inside a steel pipeline, comprising an alternating or pulsating current drive coil having its axis essentially perpendicular to the pipe wall or other workpiece and surrounding at least one eddy current sensor.  The sensor is formed by a C or E shaped core, which may be either ferrite or other ferromagnetic material such as laminated iron, having the free ends  of the two or three legs thereof adjacent the workpiece, with a pair of sense coils wound approximately symmetrically on the core and connected, preferably in series reinforcement, to give a null signal in the absence of flaw.   Where an array of sensors is used within a single drive coil to increase coverage, these are preferably arranged in a chevron or herringbone pattern with chevron axes oriented in the direction of scan in order to decrease directional sensitivity.  Signal processing circuitry is provided which typically includes a narrow band pass synchronous amplifier tuned or gated by reference to the same signal that is used to drive the drive coil.

Abstract: Abstract of the Disclosure A method for feeding the growing substrate, such as peat, soil, compost, crushed mineral wool, perlite, vermiculite, or bark, by means of a feeding equipment into the cells (6) of the set (4) of growing cells placed underneath the said equipment. The feeding equipment consists of two horizontal feeding rolls (2), which are placed side by side and which are parallel to each other, pins (3) of a resilient material, e.g. rubber or plastic, preferably polyurethane, being arranged as projecting from the roll faces (7), the said pins (3) projecting radially. The pins (3) are placed in the normal planes of the axes of the feeding rolls (2) alternatingly in each feeding roll (2) so that, in the space between the feeding rolls (2), the pins (3) on the feeding rolls (2) are placed as inter-locking each other. The feeding rolls (2) are rotated in opposite directions so that the roll faces (7) of the rolls (2) directed towards each other have a downwardly oriented direction of rotation. The filling material of the cells (6), i.e. the growing substrate, is fed preferably as moist at a high speed into the cells (6) by rotating the feeding rolls (2) at a rotation speed of 500 to 1000 r.p.m. - the lower the specific weight of the filling material, the higher the speed of rotation. Thereby the filling material is, by the effect of the circumferential velocity of the feeding rolls (2) of about 3 to 10 m/s, rushed in the vertical direction into the cells of the growing cell system (4) so that any filling material introduced into the cells (6) earlier is compacted by means of the kinetic energy of the filling material, beginning from the bottom.

Abstract: ABSTRACT            A micro-sample of semen is exposed to a beam of light from an inexpensive and small laser device.  Light scattered by the sample is detected by a photodetector.  The photodetec-tor signal is analyzed in the frequency domain to provide a measure of the amplitude of the signal components having frequencies above about 100 Hz.  This measure is represen-tative of the numbers of motile sperm in the sample.  A motile/immotile percentage is obtained by dividing the motile measurement by a value representative of the ampli-tude of the full-frequency photodetector signal.  In a preferred embodiment frequency-amplitude analysis is carried out in the time domain using frequency splitting filters and integrating the filtered signals.  The light receiving aper-ture for the photodetector is made annular or part-annular in shape to overcome sample orientation or polarization effects.
