Abstract: A dental apparatus adapted for penetrating and cleaning the interstices and interproximal surfaces between the teeth, the surfaces at and below the gum margins, and the tooth-gum interfaces including the grooves and crevices thereof, is provided. In a preferred embodiment, a neck portion interconnects an elongated handle portion and a head portion, with the head portion being angled upwardly of the handle portion. A plurality of tufts of bristles are fixedly attached to the face of said head portion, said tufts of bristles having wedge means and conforming means to enable penetration into and cleaning of said interstices, surfaces and interfaces. A single row of a plurality of tufts of bristles, disposed substantially perpendicularly of said handle portion, has the free end of each of said plurality of tufts which are disposed at said end of said head portion beveled, said bevel sloping upwards from a vertex formed at said free end of the outermost bristle in each of said tufts. The tufts of bristles also have a plurality of bristles of varying lengths such that a concave surface generally corresponding to the convex configuration of the surfaces of the teeth is formed by the said free ends thereof. The longer bristles have the firmness substantially the same as the bristles of conventional hard-bristled toothbrushes and the shorter bristles have the firmness substantially the same as the bristles of conventional medium-bristled toothbrushes. In accordance with the concept of the present invention, the contours and configuration of the tufts of bristles in combination with the relative lengths and firmness thereof, afford a convenient and reliable apparatus and method to penetrate and clean the hard-to-reach surfaces and embrasures of the tooth-gum interfaces.

Abstract: A flowmeter for gases, comprising a rotor (11) between two stators (3,3 min ) which consist of deflection blades, optical means being provided to detect the rotation of the rotor and convert it into an electrical output signal. Each of the detector blades of the stators has a curved course between an inflow edge (7), where the blade face from the hub (9) to the periphery runs substantially axially, and an outflow edge (8), where the blade forms an angle with the axial direction which angle depends on the distance from the hub. Preferably the blade face is at least partially (18) formed by a circular cylindrical face (15/17), the central axis (14/14 min ) of said cylinder intersecting the central axis (12) of the stator at an angle differing from 90 DEG  at such a distance that the central axis of the stator lies in a tangent plane to the cylinder, and a flat face part (22), passing through the central axis (12) of the stator, connects to the circular cylindrical part (18) of the stator face up to the inflow edge (7), the axial measurement of said flat face part (22) decreasing from the hub (9) to the peripheral edge (4). The flowmeter can be cast and presents an excellent reproducibility of its features between individual units, in the two positions, and it has a great dynamic range.

Abstract: For tensioning a cable having multiple strands (A, B, C, D, etc.) by the successive tensioning of the various strands by means of an individual jack (4), the following procedure is adopted: a first cable strand (A), hereafter called a "reference strand", is tensioned, whilst at the same time making it possible subsequently to measure the tension of the strand at any moment, a second strand (B) is then pulled until its tension is equal to that of the reference strand, measured at the same moment, and thereafter this second strand thus tensioned is anchored, a third strand (C) is then pulled until its tension is equal to that of the reference strand, measured at the corresponding moment, and thereafter this third strand thus tensioned is anchored, and so on and so forth until the last strand (D) is anchored, after which the tension then applied to the reference strand (A) is noted and, after the latter has been relieved and the measuring means released, this reference strand is anchored by applying the tension thus noted to it.

Abstract: A method for electronically detecting when a solenoid has closed, or nearly closed, indirectly senses changes in the inductance of the solenoid's coil as the solenoid closes. When the inductance has changed by a selected amount, the solenoid is assumed to have closed, or nearly closed, and current through the coil is promptly reduced. Preferably, changes in the inductance of the coil are sensed by establishing a plurality of current peaks in the coil, and sensing the current's decay time between peaks. When the decay time of a measured current peak exceeds the decay time of a previously measured current peak by a selected amount, it is assumed that the solenoid has closed, or nearly closed.

Abstract: A rotary cutter for fly cutting metal sections comprising a pair of opposing blades, (21,22) top and bottom, which at one end have arms operationally linked to a control system capable of setting them in rotary motion, the said blades having guide teeth (24,25) co-operating with them with the purpose of preventing interference of the cutting edges (26,27) of the blades (21,22) during the cutting stage. According to the invention the cutting edges (26,27) of the blades (21,22) are straight and lie in different planes to those in which the said guide teeth (24,25) lie, the latter having a curved contour which determines a certain angle with the contour of the cutting edges. In this way the cut can occur in a plane which is essentially perpendicular to the longitudinal axis of the metal section to be cut. <IMAGE>
