Patent DE-4341861-A1 (DE)
Title: Fuel injection pump unit
Inventor: COOK GRAEME ALFRED CYRIL
IPC: F02M59/26
Filed: 1993-12-08
Abstract: The pump has a cam actuated plunger (13) which is moved inwardly in a bore (12) to displace fuel through an outlet. A port (27) is formed in the wall of the bore (12) and at some position during the inward movement of the plunger in uncovered by a control edge (30) to allow fuel to escape from the bore via an axial groove (29) and a circumferential groove (31).In order to damp the final inward movement of the plunger the flow of the escaping fuel is restricted. To this end, the circumferential groove (31) may be of reduced width so that an edge progressively covers the port to restrict the rate of escape through the port.

Patent DE-4407278-A1 (DE)
Inventor: GOEBEL HERBERT DR
IPC: G01N23/207
Filed: 1994-03-04
Abstract: Conventional X-ray analysis devices usually operate on the Guinier, Seemann-Bohlin or Bragg-Brentano focussing principle. Here, the sample to be examined must meet certain geometrical requirements, and this is often impossible in practice. The object of the application is an analysis device fitted with a conventional X-ray tube (4) in which the sample is illuminated by a parallel monochromatic beam (7') and the deflected X-radiation (13) is detected as a parallel beam. The monochromator used is a parabolically curved multi-layer mirror ("graded-Bragg" structure (5)), the period of which changes over the length (1) of the reflector (5) in such a way that radiation of a given wavelength is always Bragg-reflected in the same direction regardless of the angle of incidence. Parallel-beam X-ray diffractometer, parallel-beam X-ray reflectometer.

Title: Cooling zone of a furnace,in particular of a roller furnace
Inventor: CREMER G
IPC: F27D5/00
Filed: 1981-08-28
Abstract: The cooling zone (K.Z.) pertains to a furnace, preferably a roller furnace, comprising a preheating zone (V.Z.), a firing zone (B.Z.) and a cooling zone (K.Z.). The articles to be fired, preferably ceramic slabs or plates, are conveyed through that furnace, in one layer without refractory material support. The zone (K.Z.) is indirectly cooled in order to prevent, in this zone (K.Z.) and its neighbourings, the atmosphere from acting on the articles to be treated, thereby avoiding a re-oxidation of said articles (B), and it is possible to act on their outer surface in a simple manner by means of a heat-carrying flow, preferably a heat-conveying fluid. The cooling zone comprises members which are adjustable in direction and flow rate for injecting materials acting on the surface of the articles. The indirect cooling is achieved preferably by means of coils (3) arranged above the articles to be subjected to the firing (B); their radiating surfaces may be masked in an adjustable fashion (in 5) and are arranged transversely with respect to the direction of movement of the articles. The masking elements (5) may be pivoted to swing like the blades of a blind or be made of sliding plates, movable towards each other. The coils (3) may be connected with other parts of the furnace, or with heat recovery installations.

Patent WO-9853282-A1 (WO)
Inventor: VOELKEL HARDI
IPC: G01F23/296
Filed: 1998-05-14
Abstract: The invention relates to a vibration filling level limit switch and a method for determining and/or monitoring the filling level of a medium in a container. A mechanical vibrating formed body (1, 10) is excited with a piezo-electric excitation device (3, 11) until it vibrates. Said vibrations are detected by a receiver converter (4, 12) which is substantially identical to the excitation device (3, 11). The response signal of said vibrating formed body is determined in a converter circuit (14, 14') by comparing the receiver converter (4, 12) output signal with the output signal of a reference element (13). The response signal, which is optionally converted into rectangular pulses, is amplified and fed back to the input of the excitation device (3, 11) and the reference element (13), so that the vibration of the vibrating formed body (1, 10) is continuously stabilized at its own momentary frequency. According to the way in which the inventive device is used, said own frequency is compared with a given frequency corresponding to a given filling level limit or the amplitude of the response signal is evaluated. The invention has a simplified mechanical structure and energy consumption is reduced.

Inventor: KIESSLING BERND
IPC: G01B11/06
Filed: 1999-03-23
Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur berührungslosen Messung der Dicke von transparenten Materialien. Es steht die Aufgabe, auch an nicht ideal glatten Meßobjekten zuverlässig Reflexe und damit Meßwerte bereitzustellen, die zugleich nicht durch keilige Wandungen und Verkippungen des Meßobjektes verfälscht sind und die auch bei stark gekrümmten, keiligen Wandungen trotz begrenzter Apertur der Empfangsoptiken auswertbare Reflexe auf den Sensoren liefern. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Licht aus den Leuchtflächen (11 und 21) jeweils zunächst kollimiert und anschließend unter einem Einfallswinkel zur Oberflächennormalen auf die Oberfläche des Meßobjektes (1) fokussiert wird und die beiden Reflexe des Lichtes, die an der Vorder- und Rückseite auftreten, weiterhin jeweils auf den opto-elektronischen bildauflösenden Sensor (26 und 16) abgebildet werden, wobei die den Leuchtflächen (11 und 21) zugeordneten Abbildungssysteme identischen Aufbau zeigen, aber das Meßobjekt (1) mit gegenläufigen Strahlengängen beaufschlagen.
