IPC: A61C5/12
Filed: 1991-09-05
Abstract: A method for retaining a dental dam comprises the steps of positioning a dental dam (11) over a plurality of teeth in the mouth of a patient;  selecting a section of elastomeric cord (10); elongating the section to reduce the cross-sectional area thereof; interposing a portion of the elongated section between at least two adjacent teeth and over the dam; and allowing the section to expand toward its original cross-sectional area thereby prohibiting the removal of the dam from the teeth. Also provided in combination with a dental dam (11) having a plurality of individual holes to fit over a like plurality of teeth in the mouth of a patient, is an elastomeric cord (10) having a first, relaxed diameter and a second elongated diameter of lesser dimension than the first, the second diameter being interposed between a pair of adjacent teeth and over the dam in position with respect to the teeth, wherein the first diameter forms an elastomeric wedge between the teeth to retain the dam. A novel elastomeric cord (10) is provided for retaining a dental dam which is preferably provided in a column (40). A method for manufacturing the column is taught as is the use of such a column in combination with a container (50).

Title: Process for compensating the non-uniformity of a surface wave convolver
Inventor: FILBERT DIETER
IPC: H03H9/72
Filed: 1990-05-11
Abstract: Abstract 1.  -   Process for obtaining a compensation quantity to compensate the nonuniformity of a surface wave convolver 2.1     A surface wave convolver  (C)  consists of  an elongate piezoelectric crystal,  to the ends of which interdigital transducers are fitted to convert electrical input signals applied to signal inputs  (E1, E2)  into acoustic surface waves. At its integration electrode it is possible to pick off an output signal (c(t)) which corresponds to the convolution product of the electrical input signals. 2.2.    In order to compensate errors  caused by the nonuniformity of the  surface  wave convolver (C) in consequence of inhomogeneities  of  its  integration electrode and of the piezoelectric crystal, a constant input signal  (u(t))  is applied to one of the signal inputs (E1) and a predeterminable signal (v(t)), which determines a desired pulse response of the surface wave convolver (C), is applied to the other signal input (E2) of the surface wave convolver (C). The output signals (c(t)) are freed from stochastic disturbing components by averaging to form the compensation quantity (K(t)). The compensation quantity is fed to the output signal (c(t)) of the surface wave convolver (C) with the pre-determinable signal (v(t))  in synchronism, when input signals (u(t)) to be processed are applied to the signal input (E1). 2.3.

Title: Direct memory access for data transfer within an i/o device
Inventor: JACOBS MICK R
IPC: G06F13/12
Filed: 1992-02-07
Abstract: Within a computing system an input/output device connects an input/output bus to an external data port.  Data is transferred between the input/output bus and the external data port.  A controller within the input/output device transfers data between the external data port and an internal memory.          Direct memory access circuitry within the input/output device transfers data between the internal memory and the input/output bus in synchronization with data transfer across the input/output bus.  Data transfers to and from the internal memory are arbitrated so that the controller does not transfer data between the external data port and the internal memory simultaneous to the direct memory access circuitry transferring data between the internal memory and the input/output bus.

Abstract: Perforatrice à percussion hydraulique dans la roche comprenant un manchon d'usure (12) et un piston placé dans le manchon d'usure où il peut coulisser. Des surfaces de pression d'avancement (58) et de retour (32) polarisent le piston entre des positions d'avancement et de retour respectivement. Un orifice de haute pression (18) est inclus. Une chambre de retour (22) est exposée à la surface de pression de retour (32). Une chambre d'avancement (36) est exposée à la surface de pression d'avancement (58). Une soupape sensible à la pression (42) peut se déplacer entre une position ouverte et une position fermée. Quand la soupape (42) est en position ouverte, l'orifice de haute pression (18) est raccordé à la chambre d'avancement (36). La soupape (42) comporte une première surface de pression (48) pour exposition à la chambre d'avancement et une deuxième surface de pression (46) pour exposition à l'orifice de haute pression. Une troisième surface de pression (50) de la soupape est exposée à un orifice de pression d'échappement (54). Le volume de fluide se déplace entre l'orifice de haute pression (18) et la chambre d'avancement (36) losrque la soupape (42) est en position ouverte et il peut être limité à volonté pour différentes applications de forage. L'utilisation de la soupape (42) pour contrôler la haute pression dans la chambre d'avancement (36) a aussi pour résultat un état souhaitable pour le forage dans la roche. Cet état permet à l'orifice de haute pression (18) de ne pas être raccordé à la chambre d'avancement (36) pour la plus grande partie de la course de retour du piston, mais d'y rester raccordé pour la plus grande partie de la course d'avancement du piston.

Inventor: MAEKINEN JUKKA
IPC: B65C9/22
Filed: 1992-09-11
Abstract: This patent publication discloses a method and assembly for placing an identification label to the end of a paper roll (1). Prior-art methods for placing the label have been hampered by the long duration of the work cycle caused by the picking movement of the label. According to the present invention the label is picked by means of a clamp element (7) from a slanted surface inclined at an angle of, e.g., 45° from horizontal and transferred to the end of the roll (1) via an activation phase of the adhering surface by way of a continuous horizontal transfer movement, thus achieving a short work cycle. The assembly designed to implement the method performs the transfer movements by means of an arm (6) travelling along a guide rail (5) and a clamp element (7) connected by a joint (8) to the end of the arm (6).
