In one aspect, a circlip includes a circlip body defining (i) a first end surface, (ii) a second end surface spaced circumferentially from the first end surface so as to define a gap between the first and second end surfaces, and (iii) an outer curved surface defining an outer perimeter of the circlip body. The outer curved surface extends from the first end surface to the second end surface. Further, the circlip includes at least one row of teeth defined at the outer curved surface, and extending from at least one of the first and second end surfaces circumferentially along a direction away from the gap. When installed in a circlip groove, the teeth engage the circlip groove to limit rotation of the circlip within the groove.

This invention provides a self-clamping device for hanging objects from a supporting element. In one embodiment, the device has a body, a holding arm, a pivot arm and a clamping arm, the pivot arm and the clamping arm are affixed to the body, the holding arm projects from the body forming a holding point between the holding arm and the body for hanging objects; and the pivot arm is configured to contact a top side of the supporting element, forming a pivot point; an object hanging from the holding point generates a torque about the pivot point to thrust the end of the clamping arm against a bottom side of the supporting element forming a clamping point.

Various implementations include a device for holding and supporting a medical instrument in a position. For example, the medical instrument may include a percutaneous procedure apparatus, such as a needle (e.g., biopsy needle, anesthesia needle) or needle holder. In some implementations, the device holds and supports the percutaneous procedure apparatus and liberates the procedure operator's hands from direct beam exposure, which lowers the risk of complications and radiation exposure to patients and procedure operators. The device also increases the effectiveness of the procedure by holding and supporting the apparatus in the intended position.

The invention relates to a chassis for a utility vehicle, having a first .sup.J chassis element extending transversely with respect to the vehicle longitudinal direction and a second chassis element (5) fixed to the outer side thereof, wherein the second chassis element (5) is supported against the outer side of the first chassis element via at least one roughened supporting area (11, 12). In order to avoid relative movements between the chassis elements connected by clamping forces in a utility vehicle chassis, the roughening comprises a surface structure produced by machining the supporting area (11, 12) in a blasting process and preferably a laser beam process. The invention further relates to specific individual parts of such a chassis, specifically an axle shell, an axle guide (5), and a brake carrier.

This Application seeks to protect Applicant's HYTORC® Z® System which involves: tools having multi-speed/multi-torque modes with torque multiplication and vibration mechanisms without use of external reaction abutments; a force transfer means to yield in-line co-axial action and reaction for use with such tools; driving means and shifting means capable of attaching to washers under the nut for use with such tools and force transfer means; associated washers and fasteners for use with such tools, force transfer means and driving means; and related accessories for use with such tools, force transfer means, driving means, washers and fasteners. The HYTORC® Z® System includes the following: Z® Washers located under nuts or bolt heads of various types having engageable perimeters of multiple shapes, sizes, geometries and serrations, such as washer/fastener radius engagement differentials, and frictionally biased faces with relatively higher friction against the flange surface and relatively lower friction against the nut, such as friction coefficient increasing treatment means of various types, sizes and locations; HYTORC Z® Guns incorporating a powerful intermittent (impact, vibration, ultrasonic, etc.) mechanism, a precise torque multiplier in the same tool combining rapid run-down with calibrated torque; HYTORC® Z® Sockets with dual drive coaxial action and reaction having outer sleeves to react on Z® Washers and an inner sleeves to turn nuts or bolt heads; HYTORC® Z® Spline Adapters and Reaction Plates for backwards compatibility with HYTORC®'s torque/tension systems including the AVANTI® and ICE® square drive systems, the STEALTH® limited clearance system, the pneumatic jGUN® series, the FLASH® Gun and LITHIUM Series electric multipliers and more; the combination of HYTORC Z® Washer and the HYTORC® Z® Dual Friction Washer™ including a dual friction-enhanced face washer and/or the HYTORC® Z® Nut/Bolt for counter-torque under a nut or bolt head on the other side of the joint; HYTORC® Z® Dual Drive Offset Links for tight clearances while using HYTORC®'s torque/tension systems; HYTORC® Z® Vibration Mechanisms applied thereof; Z®-Squirter® Washers; Z®-DTI Washers; HYTORC® Z® Washer and Nut Assemblies; Anti-Loosening Z® Washers; and any combinations thereof. Further disclosures include: Tapered Fastener Assemblies; Tapered Torsional Couplings; Two-Part Tapered Nut Assemblies; Two-Part Tapered Thread Nut Assemblies; HYTORC® Anti-Loosening Z® Washers, Nuts and SMARTSTUDS; and any combinations thereof.

An accessory for a clamp assembly includes a grip element which has a base portion including two opposite end faces, rows of teeth that protrude from the base portion, the teeth being arranged in rows with gaps separating them, wherein each of the teeth has a shape as viewed from one of the end faces which includes a first shape portion which has straight sides each of which extends from the base portion to an end, wherein a junction of each of the straight sides with the base portion has a radius, wherein the straight sides form borders of the gaps. Each of the teeth includes another shape portion that extends inwards, away from the gaps. The ends of the straight sides of the first shape portion and the other shape portion cooperate to grip a pipe.

A clamping device includes first and second clamping components and at least one elastic component. The first and second clamping components include first and second rear portions and first and second front portions pivoted to each other respectively. The first and second rear portions are pivoted to each other. The elastic component connects the first and second clamping components. The first and second clamping components rotate, with respect to each other, to a first state due to an elastic force of the elastic component so that the first and second front portions have a first distance. When the first and second clamping components are subject to a force, the first and second clamping components resist the elastic force of the elastic component and rotate, with respect to each other, to a second state so that the first and second front portions have a second distance greater than the first distance.
