A lighting arrangement has a housing having an interior and a light outlet region, and at least one light-providing device. The light-providing device is configured such that it can be arranged within the interior to emit light during operation through the light outlet region to the outside. The light-providing device can be coupled to the housing and can be freely positioned at least within one region of the interior. A second lighting arrangement has a housing having an interior and a light outlet region, the housing having an opening, which is set up to guide at least one line through the opening out of the interior. The second lighting arrangement has at least one brush, which is provided with hairs or fibers or bristles, which are arranged in the opening and / or cover the opening at least in portions.

A construction having generalized and alternative joints, capable of making pillar materials self-stood at in horizontal direction of lower frame materials. Upper and lower frame materials formed by laminating three sawn plates with two or more different plate width in plate thickness direction, and a recessed groove or a protruding stripe of the alternative joints is formed between outer layer plate width of outer layer sawn plates interposing an intermediate layer of laminated layers and an intermediate plate width of intermediate sawn plate interposed as the intermediate layer. The pillar materials are formed by laminating three sawn plates with same length in plate thickness direction, and a protrusion or a recess, which can be fitted closely to the recessed groove or the protruding stripe, are formed at both ends by deviating an intermediate sawn plate in a longitudinal direction for a distance of the difference to outer layer sawn plates.

A profile element for connecting a vehicle window pane to a cover part includes a first connecting area for connecting the profile element to the vehicle window pane and a second connecting area for connecting the profile element to the cover part. A sealing element has at least a first segment and a second segment that are moveable relative to each other. The first segment has a first sealing surface configured to be placed against the vehicle window pane and the second segment has a second sealing surface configured to be placed against the cover part such that the sealing element forms a seal between the vehicle window pane and the cover part.

The invention relates to an anti-twisting assembly tool of a vehicle front lower swing arm back hydraulic bushing. The tool comprises a baseplate, a cylinder pressing device and a moving plate; the moving plate capable of sliding left and right is mounted on the right side of the upper end surface of the baseplate; a lower clamp is mounted on the left side edge of the upper end surface of the moving plate; the upper end of the lower clamp is rotationally connected with an upper clamp; two cylinders are arranged on the right side of the upper end surface of the moving plate in the length direction of the lower clamp side by side; a support base is mounted between the two cylinders; piston rods extending from the right sides of the two cylinders are connected with connecting plates arranged on one side of the support base in parallel; pressing blocks are mounted in middles of the left side walls of the connecting plates; through holes are formed in the middle parts of the pressing blocks and the connecting plates; a cylinder pressing device is mounted on the left side of the upper end surface of the baseplate; and a hole position fixing device and a limiting device are correspondingly mounted on the cylinder pressing device front and back. The tool solves the problem of relative position deflection of an inner pipe and an outer pipe of the vehicle front lower swing arm back hydraulic bushing tightened by a nut, and adopts a slide rail to realize free assembly.

The embodiment of the invention provides a method, a system and equipment for processing a signal of a 3D audio conference. The method comprises the following steps: aiming at a terminal to obtain audio streams relative to the terminal; matching marks for the obtained audio streams relative to the terminal; and combining the obtained audio streams relative to the terminal and the marks corresponding to the obtained audio streams and transmitting the obtained audio streams and the marks to the terminal. The invention can solve the problems that demands of transmission passages are excessive, and the terminal can not freely position acoustic image positions of other terminals in the prior art.

The invention relates to a gear-system arrangement (10) for driving a vacuum roll (12) and for supporting the internal structures (14) of a vacuum roll (12), which gear-system arrangement (10) includes: a machine frame (16) fitted to a supporting foundation (18), a carrier-bearing assembly (20), attached inside the machine frame (16), for supporting the vacuum roll (12) on the machine frame (16) from outside the vacuum roll (12), a gearwheel (22) attached to the vacuum roll (12), for driving the vacuum roll, a gear housing (24) for transmitting torque, a drive-bearing assembly (26) between thegearwheel (22) and the gear housing (24), a carrier ring (28) for supporting the vacuum roll's internal structures (14) from the machine frame (16), and the gear housing (24) has been integrated as part of the carrier ring (28). In addition, the gearwheel (22) and the vacuum roll (12) are connected to each other by a flexible coupling (30).

The invention discloses advertising equipment capable of turning over on three sides, comprising a driving shaft assembly and a driven shaft assembly, wherein the driving shaft assembly drives the driven shaft assembly to realize the triangular prism rotation. The advertising equipment is characterized by having the positioning function and comprising a locating assembly, wherein the locating assembly which movably coordinates with the driving shaft assembly makes a periodic movement when the driving shaft assembly rotates, the other end of the periodically-moving locating assembly coordinates with a locating structure arranged on the driven shaft assembly to realize the location of the triangular prism. The locking and the unlocking of the triangular prism is completed by a group of independent locating assemblies, the problem of big friction is overcome when the driven wheel rotates, therefore, the transmission mechanism and the triangular prism rotate freely and locate accurately, the locking and the unlocking of the locating assembly is realized synchronously with the driving mechanism and the driven mechanism without deflection, at the same time, the problem that the large power is needed supplying instantly when the motor starts can be avoided, the motor load can be greatly reduced, the failure rate can be reduced, the damage of the motor and the driving shaft can be reduced, and the maintenance cost and the failure rate can be decreased.
