The invention relates to a securing element (1; 1a) for a bearing device (50) in a housing (20) of a drive device (10), wherein the plate-like securing element (1; 1a) has two side legs (34, 35) and a base leg (36) which connects the side legs (34, 35), wherein, between the base leg (36) and the side legs (34, 35), there is formed a cutout (38) for receiving a shaft (12) which is mounted rotatably in a bearing (15), wherein the two side legs (34, 35) are designed to interact, by means of a first face side (21), with the bearing (15) and, by means of a second face side (23), with a stop surface (33) in the housing (20).

There is provided a method of manufacturing washers with improved material yield. The method includes: a preparing step of preparing a material having a panel shape; a first cutting-out step of cutting out a first thrust washer having a substantially arc shape from the material; and a second cutting-out step of cutting out a second thrust washer from a portion of the material in contact with a portion from which the first thrust washer is cut out.

A fastener for retaining a bolt in a hole in a structure, comprising a bushing integrally formed with and extending from the bottom surface of a retainer, the bushing being dimensioned for insertion into the hole in the structure and having a wall thickness ranging from about 0.005 inches to about 0.030 inches, wherein the bushing is configured to be expanded within the hole, thereby securely coupling the expanded bushing within the hole of the structure and anchoring the retainer to the surface of the structure surrounding the hole. A tool for installing a fastener, comprising a tapered mandrel configured for insertion within a fastener situated within a hole of the structure, a drive mechanism configured to retract the mandrel through the fastener and thereby expand the fastener, and a force sensor configured for measuring a force applied by the drive mechanism to retract the mandrel through the fastener.

Method and structure for reducing substrate fragility. In one embodiment, a substrate for metamorphic epitaxy of a material film is provided, the substrate comprising a passivation layer defining a growth window for the material film on a deposition surface of the substrate, the growth window being laterally spaced from an edge of the substrate.

A fastener assembly for securing two components to one another. The fastener assembly includes a barrel or pin that has a radially extending hole in the barrel. The pin also has a reduced diametrical portion on at least one end to form a shoulder and possibly on both ends. The pin is inserted into a hole formed into a hollow or sandwich component. The shoulder engages against a wall on the component to orient and secure the pin in the hole. A threaded fastener is then inserted transversely through the two components to engage in the radially extending hole. The threaded fastener is then rotated to secure the two components to one another.

The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a tensioning rail and at least one angle box mountable to a side plate. At least one bolt assembly provided for fastening the tensioning rail to the side plate and to angle box. Bolt assembly is provided with is a shoulder bolt that is secured to a terminal end of the bolt. The angle box includes an aperture sized to allow the bolt assembly passage therethrough, and a movable plate with a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position to allow access to the aperture in the angle box such that the bolt assembly can be detached from the angle box without being disassembled.

The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a support structure for supporting the screen media and tensioning rail mountable to at least one side plate. At least one bolt assembly provided for fastening the tensioning rail to at least one of the side plates. Each bolt assembly including a bolt connectable to the tensioning rail, at least one of side plates and at least one bolt engaging structure on a surface of the side plate. Each bolt engaging structure includes a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position.

A washer that includes: an inner peripheral face formed in an arc shape; an outer peripheral face formed in an arc shape concentric with the inner peripheral face on a radially outer side of the inner peripheral face; and outer peripheral cut-out portions (such as a left outer peripheral cut-out portion and a right outer peripheral cut-out portion) formed at positions of the outer peripheral face corresponding to end portions (a first end portion and a second end portion) of the inner peripheral face to have the same shapes as outside shapes of the corresponding end portions of the inner peripheral face.

A floating connection fastening system employs a semi-flexible floating bushing having a sleeve with an axial slot which captures a fastener having a head, an unthreaded shank portion, a threaded portion and an intermediate reamer. An adapter mounts to the bushing/fastener assembly and receives a driver bit. The adapter defines an offset clearance. The floating connection is installed by driving the fastener through a non-load bearing member so as to form a bore and embed the fastener into a load bearing member. The floating bushing has a flange which engages the surface of the non-load bearing member. The installation may be performed in essentially a one-step procedure.

A washer includes a single piece body made of a resilient and flexible material and having a split extending between an inner circumferential edge and a radially outer peripheral edge to provide the body with first and second ends. One end has circumferentially extending and radially spaced fingers, and the other end has circumferentially extending and radially spaced fingers. A joint structure is integrally formed with the first and second ends. The joint structure includes a first locking mechanism and a second locking mechanism. The second locking mechanism is only engageable after the first locking mechanism is fully engaged.
