Abstract: Un tambour à disques (3) comprend deux disques frontaux reliés par des tirants (3.3) et rotativement montés sur l'axe tubulaire de roulement (30). L'eau sale est introduite par un ajutage à fente (33) à travers l'axe (30) du tambour et la caisse d'introduction (32) sur le côté d'admission du brin supérieur (4, 1) et s'écoule à travers la bande de filtrage (4) même lorsque le tambour est stationnaire, ce qui entraîne la formation d'une couche de boue (36) qui réduit la perméabilité de la bande de filtrage, de sorte que le niveau de liquide (23) s'élève avec le temps. Le moteur d'entraînement (19) du tambour est enclenché au moyen d'un interrupteur à flotteur (25) ou d'un chronomètre et amène une section nettoyée de la bande dans la zone de filtrage, provoquant l'abaissement du niveau de liquide (23) qui s'élève toutefois de nouveau, de sorte que le cycle de commutation se répète. Des entraîneurs oscillants (41) suspendus sur les disques du tambour râclent le côté intérieur de la bande de filtrage et déchargent la boue ainsi élevée sur le brin supérieur (4.1) au niveau de la poulie de déviation (5.3). La bande sans fin de filtrage est composée d'un tissu ou d'un treillis de fibres, de fils ou de câbles en un matériau flexible résistant à la traction et à la pression. Afin d'augmenter le degré de pureté du liquide, cette bande de filtrage peut également servir de support à une bande de filtrage fin en non-tissé ou similaire.

Filed: 1990-01-08
Granted: 1993-02-10
Abstract: A panel slide-in device for inserting panel-like workpieces deposited on an elevating platform into panel-dividing installations is described. This device comprises a sliding member (26) which is guided in a vertically floating manner on a slide-in carriage (18), it being possible for this member, for sliding-off purposes, to be laid against the edge of a workpiece panel (24) of a panel stack (22) or of a panel packet. Mounted on the sliding member is a supporting roller (30) which projects beyond said member (26) in the opposite direction with respect to the lifting direction of the elevating platform (20). The supporting roller ensures that the edge of the bottom end face of the sliding member which faces the panel stack cannot come into contact, and damage, the upper face of the top workpiece panel of the panel stack while passing over said panel, in the event that the workpiece panel should be corrugated or warped in the slide-in direction or even transversely to this.

Abstract: A method is disclosed for the production of metal oxide ceramic membranes of very small pore size. The process is particularly useful in the creation of titanium and other transition metal oxide membranes. The method utilizes a sol-gel process in which the rate of particle formation is controlled by substituting a relatively large alcohol in the metal alkoxide and by limiting the available water. Stable, transparent metal oxide ceramic membranes are created having a narrow distribution of pore size, with the pore diameter being manipulable in the range of 5 to 40 Angstroms.

Abstract: A spread spectrum receiver subsystem for utilization in a CDMA cellular telephone having a searcher receiver for scanning the time domain so as to use the PN processing gain and time discrimination properties of spread spectrum coding to determine the location in the time domain and the received signal strength of multiple receptions of a pilot signal traveling upon one or more physical propagation paths to reception. The searcher receiver provides a control signal indicative of the received pilot signals of greatest strength and corresponding time relationship. A data receiver receives spread spectrum communication signals accompanying each received pilot signal and is responsive to the searcher control signal for acquiring and demodulating a spread spectrum communication signal, concomitant with the pilot signal of greatest signal strength, and thus providing a corresponding information bearing encoded output signal.
