The invention relates to a connecting device which has a connecting element (18) of flat beam design fixed to a wiper blade (10) and an adapter (16) joined to said connecting element in an articulated manner, and also a joining element (14) that is joined to a wiper arm (12) and into the u-shaped cross-sectional profile of which the adapter (16) is inserted and, by means of a spring tongue (64) arranged on the top wall (42) thereof, is fixed to a pushbutton (66), the connecting element (18) having a central web (28) running in the longitudinal direction of the wiper blade (10) and bearing a hinge shaft (30) projecting on the long sides thereof, which is mounted in laterally flexible hubs (46) in side walls (40) of the adapter (16). According to the invention, the outwardly facing walls of the adapter (16), namely the side walls (40), the top wall (42), and the end walls (36, 62), have a general wall thickness of at least two millimeters, and the hubs (46) are to be formed as blind holes, the cylindrical surfaces of which form radial sliding surfaces (48) and the end faces of which form axial sliding surfaces (50), which are highly polished with an arithmetic mean roughness of Ra<0.2μ, and that the sliding surfaces (48, 50) be the sole contact surfaces between the connecting element (18) and the adapter (16).

A plug-in circuit board for insertion into and withdrawal from a rack having at least one front profile rail includes a front plate and a lever-latch handle with a gripping bar pivotably-mounted to the front of the plug-in circuit board. The gripping bar includes an elastically deflectable tongue which, in the pushed-in state of the plug-in circuit board, engages the front plate by a magnetic force between a magnetized stop on the front plate and the tongue.

An electric toothbrush includes a grip portion, a brush portion, and a joint arrangement for connecting the two portions. The joint arrangement has an upper cylinder portion and a lower cylinder portion, with an axis of the upper cylinder portion being inclined a predetermined angle with respect to an axis of the lower cylinder portion. The grip portion is connected to the lower cylinder portion and the brush portion is connected to the upper cylinder portion, so that the grip portion and the brush portion are inclined by the predetermined angle.

A motorcycle neck adapter comprising a main body formed of a single piece of metal, and a cavity socket formed on an aft end of the main body. The cavity socket is configured to receive an existing motorcycle neck. An upper set screw opening is formed on a top surface of the main body. An upper set screw is installed into the upper set screw opening. The upper set screw is configured to engage an existing motorcycle neck at an existing motorcycle steering neck top opening. The upper set screw is secured to the upper set screw opening by a threaded connection. A lower set screw opening is formed on a bottom surface of the main body. A lower set screw is installed into the lower set screw opening.

A method of measuring intraocular pressure through an eyelid includes the step of subjecting the gristle region of an opened eyelid to two spaced contacts providing static support loading that deforms the eyelid. Simultaneously, the gristle region of the eyelid is subjected to the dynamic deformation of a body falling freely relative to the support contacts, such dynamic deformation being transferred to an eyeball area below the eyelid. The spaced contacts are located at equal distances from an axis of displacement of the freely falling body, thereby providing a decrease of eyeball shock absorption under the support. The amount of resilient deformation of a surface of the eyeball is then determined.

A piston/cylinder unit includes a working cylinder, a piston attached to a piston rod and arranged so that it is axially movable in the working cylinder, and a fastening element threaded into a threaded bore of the piston rod. The bore in the piston rod includes a tapered surface which widens outward starting from the diameter of the thread and the fastening element has a corresponding diminishing tapered surface arranged on a collar which diminishes from the outside to the diameter of the thread.

For making an interconnection between a valve head and stem, the interconnection between these parts is made by pouring a cast alloy around the stem end. A connection and a valve are also provided.

A light-emitting device includes a light-emitting element and a light-guiding member for causing light from the light-emitting element entering into it through one surface thereof. The light-emitting element includes a lead member with a light-emitting element chip mounted thereon and a molded member to which the lead member is secured. The lead member has a metallic part extending from the molded member, and the metallic part is bent. The thus arranged light-emitting device has an excellent heat release capability. An image reading apparatus using the light-emitting device is also provided.

A fall rescue apparatus (10) for mounting on the roof of a building includes a spike (28) mounted to an extendable support arm (27) and shaped to penetrate the roof in response to the pull of a tether (35) connected to a falling worker. An elbow linkage (39) unfolds as the spike is extended into the roof for guiding and supporting the spike against the roof.

A feeder stand including a rotary ground auger and base holds a feeder above the ground. An upright elongated rod defines a stand supported by an auger having helical coils removably screwed into the ground. A platform such as a round disc, or wire mesh platform is supported on the top distal end of the rod. At least two opposing legs extend perpendicular to the vertical elongated rod and auger forming a base. The distal end of selected opposing legs are bent or angled upward perpendicular from the ground forming handles for rotating the auger into the ground. The portion of the legs extending outward normal to the elongated support pole provides a base bearing against the ground for increased lateral support.

A bracket is provided for connecting an airbag module to a structural member in an automotive vehicle. The bracket provides three degrees to freedom to allow the fit and finish of the interior panels to be determined without being affected by the rigid connection between the airbag module and the structural member. Holes are also provided in the bracket for tuning energy management.

In a method for producing a non-detachable connection between a first workpiece and a second workpiece, a material of a workpiece region of the first workpiece is locally heated by friction heat by rotating a tool contacting the workpiece region. The material of the workpiece region is shaped to form a bush that projects beyond the first workpiece. The bush is integrally and monolithically connected to a material of the second workpiece by the friction heat contained in the material of the bush. Preferably, the first workpiece is a sheet metal and the second workpiece is a sleeve.
