Abstract: Es wird ein Fingerabdruckwandler beschrieben, der ein Abtastelement (2) umfaßt, das eine Abtastfläche (3) zur Aufnahme eines Fingerabdrucks (8) aufweist. Das Abtastelement (2) ist aus einem Material gefertigt, welches eine Übergangs- oder Erweichungstemperatur aufweist die höher als die Umgebungstemperatur und in der Nähe der Temperatur des Fingers liegt. Die Erweichungstemperatur ist insbesondere so gewählt, daß das Material des Abtastelements (2) an der Oberfläche zu schmelzen beginnt, wenn der Finger auf die Abtastfläche (3) gedrückt wird. Die Abtastfläche (3) weist ein Oberflächenrelief zufälliger räumlicher Verteilung auf. Anders ausgedrückt: die Abtastfläche (3) weist verschiedene Erhebungen auf, die kein spezielles Muster zeigen. Es wird auch ein Verfahren zur Analysierung von Fingerabdrücken beschrieben, welches folgende Verfahrensschritte aufweist: Auf einer Abtastfläche (3) eines Abtastelements (2) wird ein Oberflächenrelief mit zufälliger räumlicher Verteilung erzeugt. Auf der Abtastfläche (3) wird durch Aufdrücken eines Fingers ein Fingerabdruck erzeugt. Der Fingerabdruck wird aus der Abtastfläche (3) optisch ausgelesen.

Abstract: A diecasting process for producing cast pieces for metals or their alloys by means of a horizontal cold chamber diecasting machine. The diecasting machine includes a diecasting mold held under a vacuum, a fill chamber coupled to the diecasting mold, a holding furnace containing metal melt, a suction pipe partially immersed in the holding furnace and coupled to the fill chamber, means for transporting metal melt from the holding furnace through the suction pipe into the fill chamber under a vacuum, and means for moving the metal melt from the fill chamber into the diecasting mold. During the dosaging phase when the fill chamber is filled with metal melt, gases and lubricant vapors are developed upon entry of the melt into the fill chamber. The process includes the steps of maintaining the vacuum in the fill chamber during the dosaging phase until the gases and lubricant vapors so developed have been substantially extracted and maintaining the vacuum in the fill chamber to its maximum extent until the diecasting mold is completely filled with the metal melt.

Abstract: Corrosion inhibiting particles comprise an inorganic oxide which is silica or alumina, having corrosion inhibiting cations, particularly calcium or zinc cations, chemically bound to the particles. They may be prepared by contacting a silica or alumina containing hydroxyl groups with an alkaline solution containing the cations, at ambient temperature. The corrosion inhibiting particles may be incorporated into protective coatings, e.g. paints based on epoxy resins, alkyd resins, vinyl resins or chlorinated rubbers, in amounts up to 80% wt based on dry film weight, giving coatings with up to 7.2% wt corrosion inhibiting cations. Release of the cations is by ion exchange with other cations, e.g. the alkali metal cations of sea water, and does not, as is normal with corrosion inhibiting coatings, depend on the water solubility of the corrosion inhibitor.

Abstract: A single point fuel injection system including an electro- magnetically-operable ball valve injector (13) comprising a hollow body (14) which is surrounded by an annular gallery through which fuel is circulated under pressure continuously. Inlet ports (42 and 43) are formed in the body (14) whereby fuel from the gallery enters a chamber (44) within the body (14) in a direction transverse to the axis of the injector (13). The chamber (44) communicates with the nozzle orifice via an aperture (32) within which the ball valve (41) is located. The difference between the diameter of the aperture (32) and the diameter of the ball (41) is sufficiently small to restrict fuel flow from the chamber (44) to the nozzle orifice so that the valve (41) is urged to seat and close the nozzle orifice by the differential fluid pressure loading on it.

Abstract: The invention discloses a method of forming plastics material containers from heated plastics sheet material (32) in a thermoforming apparatus, wherein sheet material (32) is first of all displaced away from the mould cavity (28) on to the surface of a chamber (38) opposite the mould cavity (28) using a very high pressure differential, in order to induce hoop orientation in the material, and then the displaced material is moved into the mould cavity (28) against the high pressure differential and finally is shaped to the shape of the mould cavity (28). By using a chamber (38) of predetermined shape and maintained at the orientation temperature, containers having a resonably predictable degree of orientation, at least in the top region thereof, can be produced. The invention discloses also that a plug (40) and clamp (45) are used to clamp the sheet material (32) and to pull it into the mould cavity (28) against the high pressure differential.

Abstract: The method is based on the object of avoiding the disadvantages and difficulties occurring during the filling of a mould (18, 19). The method is to allow the pressure to be regulated in such a way as to allow the cooling which occurs concurrently with compression to take place entirely or partially with the specific volume of the moulding compound remaining constant, to allow the beginning of such a stage to be set and also to allow a melt cushion to be retained. The object is achieved by switching within the pressure-controlled filling phase, after an initial increase in the melt pressure in the mould cavity (17) immediately or with a delay from a driving pressure differential between injection ram or ram screw (11) and the mould cavity (17) to a pressure balance between injection cylinder (10) and mould cavity (17) and/or by the injection ram or ram screw (11) being held against melt back-pressure in the position reached at the switching instant. <IMAGE>
