In an expansible fixing plug having an internal bore passing right through the plug body into which an expansion bolt in the form of a nail or screw is to be driven, the internal bore is arranged helically wound around the center line and at least for a part of its length has a diameter that is the same as or slightly smaller than the outer diameter of the expansion bolt.

An anchor bolt has locking elements arranged over a part of the outer surface and formed as radially projecting lugs which are spaced circumferentially and axially from one another. Therefore a good mixing of a compound mass and reduction of the driving-in resistance is obtained. Therefore the outer diameter measured over the lugs of the anchor bolt can be matched approximately to the diameter of the drilled hole. Simple and inexpensive manufacture of the anchor bolt can be provided by powdered metal injection molding method using a system of binders with subsequent removal of the binders and sintering.

The expansible metal anchor (1) for anchoring in a hole drilled in a component includes a shank part (2) and an expander cone (4) having a polygonal cross-section defining several faces (13) at its front end. On each face (13) of the expander cone (4) an expansible segment (5) is arranged spaced from that face by a gap (7) corresponding approximately to the distance (8) by which the expansible segments (5) project radially from the shank part (2). Each expansible segment (5) is joined to the shank part (2) at its end face directed towards the shank part (2) by web members (6, 6') constituting predetermined break points. As the expansible anchor is driven into the hole drilled in the component, the web members (6,6') break off, so that the expansible segments (5) are displaceable on the faces (13) of the expander cone. The expansible anchor (1) is manufactured from powdered metal by an injection-molding process using a system of binders with subsequent removal of the binders and sintering, and a slide member of the mold divided at the corner edges (20) of the faces (13) is used to make the gap (7) between the expansible segments (5) and the faces (13) of the expander cone (4).
摘要:
An anchor bolt to be anchored by an explosive charge in a blind bore in a solid material, in particular a rock face or concrete, has a deformation chamber containing the explosive charge. To achieve inexpensive manufacture of the anchor bolt, simple mounting and high withdrawal values of the anchor bolt to be anchored, the deformation chamber open towards the leading end of the anchor bolt is closed by a stopper. A striking pin projecting beyond the leading end of the anchor bolt is inserted and guided in the stopper, so that as the rear end of the anchor bolt is hit the striking pin contacts an ignition capsule arranged between the stopper and the explosive charge.

The invention relates to a pharmaceutical composition comprising a compound preventing EthR from binding to the ethA promoter, for example a compound of formula 1 wherein R1 is optionally substituted phenyl or optionally substituted pyridyl; R2 (CH2)n wherein n is 1, 2, 3 or 4; R3 is CH3(CH2)m wherein m is 0, 1, 2 or 3; X1 is O, S, NH, N(CH3) or CH2; and X2 is O, S or NH; in particular 2-phenylethyl butyrate, and a thioamide or thiourea of formula 2 wherein R4 is optionally substituted phenyl, optionally substituted pyridyl, optionally substituted indolyl, —NR7R8; or —NH—N═CH—R9; and substituents R5 to R9 have the meanings indicated in the description, in particular ethionamide. The pharmaceutical composition is useful, e.g., in the treatment of multidrug-resistant tuberculosis.

An injection device having parts, the relative movement of which causes the active substance to be injected. For this purpose, a receptacle, into and in which a carpule/syringe can be inserted and mounted, is retained in a housing, the receptacle can be moved by means of a carriage, and a plunger that applies a force to the piston/s of the carpule/syringe is movably retained in the receptacle. A traction rope which is deflected by means of a roll mounted on the carriage is provided for performing the pricking stroke, injection stroke, and retracting stroke. One end of the traction rope is connected to the receptacle while the other end thereof is connected to a tension spring that is retained on the housing. Mechanisms between the housing, the receptacle, the plunger, and the carriage control the reciprocal coupling thereof to the traction rope.

A rotational damper having a stator and a rotor that is rotatably supported in the stator, the rotor having a first friction element (31, 31 A . . . 31 F), wherein the volume between the stator and the rotor is filled with a viscous fluid. According to the invention, the rotor has a second friction element (32, 32A . . . 32F), which is supported coaxially in relation to the first friction element and rotationally coupled thereto, and which can be axially displaced relative to the first friction element. Due to the two-piece design of the friction element and the ability for axial displacement of the two friction elements, the entire effective surface of the friction element in the viscous fluid, and thus the frictional resistance and the damping characteristics of the rotational damper, can be varied. For this purpose, the second friction element preferably has a plurality of segments (5, 5A . . . 5F), which immerse into the first friction element and can be displaced by an actuator (4, 4A . . . 4G). These segments bring about the rotational coupling of the two friction elements. In this manner, continuous adjustment of the damping torque can occur across a broad range using a simple mechanism, in order to meet the diverse requirements in terms of size and type of rotational damping in various applications, using only one model.

The present invention relates to a hydrogel comprising a polymer, a first polypeptide and a polypeptide binding partner, wherein the polypeptide binding partner is a second polypeptide, a nucleic acid or a small molecule, and wherein the interaction between the first polypeptide and the polypeptide binding partner stabilizes the hydrogel and is modulated by the addition of a modulating compound. A drug may be physically entrapped in the hydrogel, bound to the polymer forming the hydrogel structure, or bound to the first polypeptide or the polypeptide binding partner, and then be set free on addition of the modulating compound. Such a hydrogel comprising a drug may be injected into a patient, and drug release modulated by orally administering the modulating compound.
