摘要:
A ball catch coupling for releasably connecting two parts which permits relative rotation of the parts in the connected conditions as an annular section carried on one of the parts with a number of uniformly disposed bores at a periphery thereof, balls respectively received and rotatable in each of the bores, a closed resilient ring surrounding the balls, an annular groove in the annular section which receives the ring and permits limited axial displacement and free rotation thereof within said groove, and the other part to be connected having an annular groove which at least partially receives the ring and the balls when the two parts are connected. The limited displacement and free rotation of the ring with respect to the annular section permits engagement and disengagement to be undertaken particularly easily and with low wear.

A socket, which receives a tool having a cylindrical shaft and which is mounted for rotation to rotate the tool, has an outer sleeve which receives a clamping sleeve and a ram for engaging a first end of the clamping sleeve. The first end of the clamping sleeve is provided with slots defining resilient tongues which are moved from a clamping position radially outward to a position for releasing the shaft by engagement with the ram. The ram has either an outer conically tapered surface or partially conically outer tapered surfaces on projections which engage inner tapered surfaces of each of the tongues or fingers. Preferably, the tapers of the ram and fingers are selected so that only substantially a line contact is formed therebetween to reduce the force necessary to move the fingers or tongues radially outward to the declamping or disengaging position.

The invention relates to a vehicle door (1) and to a method for the production thereof. The vehicle door comprises a supporting frame (11) with an opening (2). The supporting frame is joined to a body structure of the vehicle in a manner that permits it to move. The opening (2) is closed in an essentially moisture-proof manner by molding it with a curable compound while forming a supporting plate (10) for accommodating elements such as window lifters, loudspeakers (3) or the like. At least one guide rail for guiding a window pane (9), which can be displaced relative to the supporting frame, is provided for accommodating a lateral edge of the window pane in the supporting plate.

A roof panel incorporating a solar power generator, for a motor vehicle sunshine roof, has a foamed plastic frame around the edge of the panel and a plurality of crystalline solar cells forming a field of solar cells extending considerably into the region of the frame. Special precautions ensure that the crystalline solar cells, which are susceptible to breakage, are not damaged when foaming around the cover to form the frame. The solar cell field enables good use of solar energy and can be accommodated in a lightweight panel.
摘要:
A stackable tapered tube body has an annular inwardly directed bead or corrugation in the region of the sealant layer. This provides that the tube bodies do not touch each other directly and that in particular the sealant layer is protected when tube bodies are stacked together.The beads or corrugations are produced by the tube shell being gripped substantially over its entire periphery, and deformed.
摘要:
A medical device for inserting into a bodily orifice or cavity of an individual, which includes a first longitudinal hollow body and a second longitudinal hollow body that receives the first hollow body. Between the one end thereof and the first hollow body, there is a stepped transition which extends in the radial direction and can pass into an at least substantially step-free transition by virtue of the fact that the first hollow body, in the region of the stepped transition, expands in the radial direction towards the second hollow body and/or that the second hollow body, in the region of the stepped transition, contracts in the radial direction towards the first hollow body.

A container closure system comprises a container having an opening zone (21) with a threaded neck (22). A closure cap (23) can be screwed on the threaded neck (22). A warranty element comprises an annular base body (25) with engagement means which can engage matching engagement means (38) in the opening zone (21) of the container. The warranty element also comprises one or more indicator elements (27) shaped as circle segments and linked each by a predetermined breaking strip to the base body (25). The closure cap (23) has at least one axial projection (34) which can be inserted between the ends of the indicator elements (27) shaped as circle segments or between the ends of two adjacent indicator elements (27) in order to secure the indicator elements (27) against rotation to the closure cap (23). When the closure cap (23) is unscrewed, these axial projections (34) break the predetermined breaking strips, separating the indicator elements (27) shaped as circle segments from the base body (25). This indicates that the container has been opened for the first time.
摘要:
To protect the quartz of a quartz glass bulb (2) from attack by alkaline earth oxides emitted from electrodes (6) of the lamp, and prevent deterioration of the quartz in use of the lamp with respect to transmission of ultraviolet (UV) radiation, particularly in the short wave length range of 200 nm to 250 nm, boron silicate glass or glass-like aluminum oxide, or a mixture of boron silicate glass and glass-like aluminum oxide is interposed between the quartz bulb (2) and the electrodes. Boron oxide can be applied to the interior of the quartz bulb, and fired thereon to form, for example, a boron silicate glass layer (4) or diffuse into the quartz glass to form a diffusion layer (4') by suitable selection of firing temperatures. Alternatively, an aperture support element (35, 45) can retain a disk of boron silicate glass or glass-like aluminum oxide positioned between the electrodes and the quartz glass bulb. Such disk elements may be planar or of lensetic shape, positioned transverse to the radiation beam axis (10, 310) or at an angle thereto, to provide for partial transmission and reflection, for example in a dual-beam control or measuring system.
摘要:
An improvement of a device for protecting manipulators against collision with other objects. Two discs are held in spaced relationship by spacer balls applied thereagainst on the periphery. The discs are urged toward each other and the gap is adjustable. If due to a collision, the position of the spacer balls is changed, the discs move toward each other, thereby causing actuation of a switch and a disconnection of the drive.

A travelling-wave tube comprises a delay line section, an electron collector comprising several electrodes in a cooling chamber, one end wall of which is connected to the delay line section, the several electrodes being individually mounted on an inner wall of the cooling chamber by insulation with good heat conduction characteristics and individually electrically connected to insulated bushings in the said end wall.
