IPC: A61C5/12
Filed: 1991-09-02
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).

Abstract: A form-fill-seal packaging machine, which pulls out an elongated film (4) from a roll (11) and transports it to a former (6) to form it in a tubular shape, includes a mechanism with two parallel rollers such that the film path can be shifted transversely. The two rollers are formed as two sides of a linked parallelogram unit, of which the shape is automatically changeable according to the direction of the rollers so as to reduce the transverse distance by which the film (4) will have to slide on the rollers. According to another embodiment, the packaging machine has its film-supporting shaft (3) extending in a backward direction. A horizontal roller (42) disposed diagonally to the path of the film causes it to turn by 90 degrees towards the former at a front part of the machine. This diagonal roller (42) is adapted to move horizontally in the forward-backward direction, depending on the width of the film (4) being transported such that the film is accurately directed to the former (6). A pair of such packaging machines, plane-symmetrically built with respect to each other, can be used advantageously in combination with a weigher having two discharge chutes because of the reduce separation between their formers (6).

Abstract: The invention relates to a method for determining the electrical system leakage effective between power system and earth, a measuring signal being injected between power system and earth, the system leakage current flowing due to the measuring signal via the system leakage between power system and earth causing a voltage drop and this voltage drop being evaluated as output signal for determining the system leakage. To provide for reliable evaluation of the individual system leakage variables, namely the resistive and capacitive system leakage variables in any power systems, even those with low-frequency faults, it is proposed, in accordance with the invention,   a) that at least two constant-amplitude period alternating measuring signal voltages or at least two constant-amplitude periodic alternating measuring signal currents are injected as measuring signals which exhibit measuring signal frequencies (f1, f2) which are as low as possible and are within a range largely free of interference signals and differ from one another and from the power system frequency (fN), b) that an absolute-value quotient (K1 and, respectively, K2) is determined for each of the different measuring signal frequencies, in connection with which   b1) in the case of alternating measuring signal voltages to be injected, these are injected into the power system via a resistor-type power system coupler and in which case in each case the absolute-value quotient between the voltage amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal voltage and the voltage amplitude - or a quantity derived therefrom - occurring across the resistor-type power system coupler - of the associated fundamental or harmonic of the output signal is measured, whilst b2) in the case of alternating measuring signal currents to be injected, these are injected directly into the power system without resistor-type power system coupling and in which case in each case the absolute-value quotient between the current amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal current and the voltage amplitude - or a quantity derived therefrom - occurring between power system and earth of the associated fundamental or harmonic of the output signal is measured,   c) and that the two system leakage quantities (RE, CE) are determined from fixed functional relationships which in each case depend on the two measuring signal frequencies (f1, f2) and the two absolute-value quotients (K1, K2).   <IMAGE>

Abstract: A nozzle for an ink-jet printer is provided having a gradually converging inner diameter leading to an orifice less than 15 microns in diameter and having an outer nozzle diameter proximate the orifice at least as great as the outer diameter at other points along the nozzle. The nozzle is produced by heating a vitreous tube (26) while rotating it, until a portion of the tube is sufficiently viscous to cause the inner diameter (70) to converge at an angle between 5 and 25 degrees with respect to the axis of symmetry of the tube, and until the inner diameter (70) is less than a selected orifice diameter. The gradual taper is achieved without drawing or pulling the tube and it facilitates achieving a desired orifice dimension during removal of a portion of the tube having an inner diameter less than the selected orifice diameter. The extremely small orifice size enables an ink-jet printer to deposit droplets of ink sufficiently small to make photographic-quality gray scale and color images.

Abstract: The present invention is a method for automatically detecting and correcting a wide range of local digital image defects with minimal user intervention. The detection process employs brightness and color thresholds in conjunction with magnitude thresholds on residuals of nonlinear spatial filters to separate defects from scene content with minimal confusion. The detected defects are then cosmetically corrected by combinations of nonlinear smoothing and grey-scale erosion. Several options are outlined for the feature selection, detection, and cleaning operations depending on source type and computational constraints.

Abstract: A distributed amplifier (100) comprises an input side circuit (100a) including a plurality of distributed constant lines (3a,3b,3c) connected in series between an input terminal (1) and ground and a plurality of source-grounded FETs (11a,11b) for switching operation having drains connected to junctions between the distributed constant lines (3a,3b,3c), an output side circuit (100b) including a plurality of distributed constant lines (3d,3e,3f) connected in series between an output terminal (2) and ground, and a plurality of source-grounded amplifier FETs (7a,7b) having gates connected to junctions between the distributed constant lines (3a,3b,3c) of the input side circuit (100a) via capacitors (9a) and drains connected to junctions of the distributed constant lines (3d,3e,3f) of the output side circuit (100b). In this structure, since the input side circuit (100a) also serves as a distributed switch, when a T/R module is fabricated using the distributed amplifier, it is not necessary to add a distributed switch for controlling signal input and output, so that the chip size of the T/R module is reduced compared to the conventional T/R module. In addition, the signal transmission loss is reduced.
