Abstract: ABSTRACT OF THE DISCLOSURE           A method for the manufacturing of a metal core pc board which provides for manufacturing of two or three dimensional metal core pc boards of any form with or without throughplating.  The manufacturing of such pc boards can occur by injection molding, injection/compressing molding or by a pressing method.  High-heat resistant theremoplastics, as well as duroplastics are preferably employed as pc board materials.          A metal with good thermal conductibility is used for the core.          The material is selected such that the thermal expansion coefficients of the metal core and the pc board material are optimally equal.  The manufacturing contains the following steps:  lamination of the metal plate with a plastic foil on one or both sides; introduction of the desired hole pattern with a corresponding over dimension into the laminated metal plate; placing of such prepared metal core in an injection molding tool: and thermoforming the plastic on the laminated core over the plastic foil and simultaneously filling out the holes to a final dimension with the plastic.

Abstract: A fan drive clutch is provided which includes a fluid coupling for coupling a drive shaft and a clutch housing on which a fan for blowing air to a radiator is disposed.   This clutch has a pump plate for defining a fluid reservoir chamber and a working chamber.  The pump plate  includes a valve opening through which working fluid passes from the reservoir chamber into the working chamber.  The fan drive clutch further includes a valve arm which has a valve plate for opening and closing the valve opening.   The valve arm includes an elastically transformable section at a connecting portion between it and the valve plate.  This section is operable to absorb movement of the valve arm which may be caused due to a clearance between the shaft for supporting the valve arm and the bearing hole for rotatably supporting the shaft. Therefore,  an  entire  surface  of  the  valve  plate  is maintained in contact with the facing surface of the pump  plate  to  hermetically  close  the  valve  opening without occurrence of any gap therebetween regardless of the movement of the valve arm.

Abstract: A roof covering or wall covering for a building or the  like  comprising  a  supporting  layer  having  open channels,  preferably  made  of  corrugated  metal  sheet. Encasing   structures,   filled  with   a   fire-retarding substance, are located in the channels of the supporting layer.    The  fire-retarding  substance  is  preferably  a thickened liquid.  Since the liquid is thickened, it cannot escape or can escape only very slowly from leaky points in the supporting layer in the event of fire.  This ensures an evaporation of the fire-retarding liquid to remove the thermoenergy produced during the fire.

Abstract: By a method for connecting a plastic pipe end (4 and 4', respectively) to a plastic welding sleeve (1) a heater (3) of annealed expanded metal is initially mounted on the pipe end (4 and 4', respectively), whereafter the welding sleeve (1) is pushed over said pipe end. Subsequently the plastic welding sleeve (1) is pressed downwards to abut the heater (3) in question by means of a known clamping device and heat supplied from the outside. The heater (3) is then connected to a welding generator and a microprocessor measuring and controlling the current through the heater and the voltage across the heater (3) during the entire heating phase. During the first phase of the heating process the heater (3) is supplied with a constant current, and when the microprocessor registers that the increase in voltage per time unit has dropped below a predetermined level corresponding to a specific temperature, said microprocessor computes the ohmic resistance of the heater corresponding to a desired predetermined final welding temperature. This final welding temperature is kept constant for a period thereafter. In this manner a method is provided for connecting a plastic pipe end to a plastic welding sleeve by means of an extensible heater. During the fully automatized welding operation this heater is situated in the welding area, whereby a uniform distri bution of heat is ensured and results in a welding of high strength and quality.

Abstract: A collector device for collecting, metering and holding a small sample of liquid, e.g. a drop of blood taken from a finger prick, comprises a vessel (10, 11 or 10A, 52A) provided with an opening (20 or 20A) closed by a plug (22 or 22A), and a screwthreaded cap (15 or 15A) having a protruding spigot (30 or 30A) which, when the cap is screwed fully onto the vessel, enters the opening and pushes the plug down into the interior of the vessel. The plug is formed at its outer end with an outwardly facing recess (24), e.g. part- spherical, and the spigot is formed at its end which enters the opening with a tapering conical formation (31) adapted to enter the recess (24). In use, with the cap (15 or 15A) removed the recess (24) is filled with a quantity of liquid, the cap is then partly replaced to cause the spigot (30 or 30A) to abut the end of the plug (22 or 22A) so that its conical formation (31) enters the recess (24) and displaces excess liquid therefrom, trapping a metered sample of liquid of predetermined volume, less than the volume of the recess, in the space defined between the abutted ends of the plug and spigot. The cap (15 or 15A) is then screwed fully home causing the spigot to push the plug down until it falls into the vessel, thus transferring the metered liquid sample into the vessel whose opening (20 or 20A) is now closed by the spigot (30 or 30A). The device enables a metered quantity of blood to be collected and transferred into the closed vessel for subsequent analysis, without contamination of the exterior of the device by the blood, and without the use of delicate metering devices such as capillary tubes to meter the blood sample. A latch connection (55A, 59A) may be provided between the cap (15A) and a removable lid (52A) of the collection vessel whereby when the cap is unscrewed it slowly withdraws the lid and opens the vessel.
