Electromagnetic brake (1) for motor drives (20) configured to rotate drive shafts of roller shutters, which electromagnetic brake (1) comprises a core (4) made of ferromagnetic material, a copper wire coil (5) arranged on the core (4) so as to form an assembly (7), the coil (5) being intended to generate electromagnetic fields by means of the electric power supply, a covering casing (6) with a respective cap (2), means (8) for coupling the cap (2) together with the assembly (7), a disc (10) intended to be moved between an active configuration, in which it is in contact with the body of an electric motor (22) of a motor drive (20) so as to prevent rotation of a drive shaft, and a passive configuration, in which it is spaced from the body of the electric motor (22) so as to allow rotation of the drive shaft, and a spring (9) arranged between the assembly (7) and the disc (10). The disc (10) is kept in the active configuration by the spring (9) and is moved into the passive configuration by means of the electromagnetic attraction effect due to the electromagnetic fields generated by the electrically powered coil (5). The coupling means (8) comprise at least one spring washer (8A) and a Seeger ring (8B).

An apparatus (2) for applying a flexible spacer to a glass plate (1) comprising an applicator (20) for flexible spacers, and a support backing (10) for the glass plate (1). The support backing (10) comprises a lateral support (102) and a translator (103). The lateral support (102) comprises an inlet support (1021), a process support (1022), and an outlet support (1023), wherein the process support (1022), arranged between inlet support (1022) and outlet support (1023) is adapted to contrast the action of the applicator (20) according to a direction (Z) substantially perpendicular to said lateral support (102). Furthermore, the apparatus comprises a translator (103) adapted to move along a direction (X). The apparatus comprises a contrasting device (106) comprising a contrasting element (1063) adapted to be moved between a support position, in which it forms a continuation of said process support (1022), and a retracted position, in which it is adapted to allow the passage of the translator (103).

本实用新型公开了一种用于中空间隔条的拐角连接件，包括连接件本体，所述连接件本体适用于铝合金窗框拐角拼接处的45°斜面。本实用新型连接件本体的L形结构与铝合金窗框90°拐角形态完全匹配，45°斜面贴合面与窗框拼接斜面的间隙较小，无需反复调整位置，连接件本体的L形结构自带90°定位基准，插入型材槽后可直接保证窗框拼接后的拐角精度，通过设置倒刺本体，保证了连接件本体插入进铝合金窗框内的稳定性，同时通过设置防滑块，提高了连接件本体插入进铝合金窗框内的摩擦力，半圆形防滑块可抵抗铝合金与连接件的形变差异，防止连接件与型材槽相对滑动，提高了连接件插入进铝合金窗框内的稳定性。

To provide a renovation fitting capable of restricting the movement of a cover material in the longitudinal direction.SOLUTION: A renovation fitting 1 includes: an existing frame 2 that is attached to an opening of a building structure 100; a new frame 3 to be attached to the inner circumference of the existing frame 2: a long cover material 335 to be attached to the new frame 3; and a regulatory structure 342 for regulating the movement of the cover material 335 in the longitudinal direction.SELECTED DRAWING: Figure 8

A coupler 100 is provided for coupling a glass panel 185 to a door 180 via a frame 115. The coupler includes a first coupling member 110 and a second coupling member 120. At least one of the coupling members includes holders 13, 114 for engaging said door and glass panel. The second coupling member includes an engagement member 111 that extends in a direction to secure position of the first and second coupling members on said frame. The engagement member may be a resiliently biased hook. A coupler system is also provided. [Fig 2]

A panel structure including: a first surface plate and a second surface plate forming a pair; and a core plate disposed between the first and second surface plates, the core plate having a plurality of protrusions arranged in a matrix on a first main surface thereof facing the first surface plate. Each of the plurality of protrusions has a protrusion tip surface facing the first surface plate. The core plate and the first surface plate are bonded to each other such that each of the protrusion tip surfaces is in contact with the first surface plate and is constrained by a plurality of planar separate constraint regions corresponding to a planar shape of said each protrusion tip surface.

Ladders and ladder components are described herein, including multipurpose and adjustable ladders. In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.
