A removal system (1) with an extraction head (2) that may be placed onto an opening of a bottle (3)), wherein the extraction head (2) has a closing means for closing the opening of the bottle (3). In the extraction head (2), a tube (5) is mounted such that when the extraction head (2) is placed onto the opening, the tube (5) projects into the bottle (3) and fluid (4) may be removed from the bottle (3) via the tube (5). An actuation mechanism is provided, by means of which the mounting of the tube (5) in the extraction head (2) may be released.

A prosthetic attachment system includes an insert arranged for connection to a prosthetic liner, and an attachment unit arranged for connection to a distal end of a prosthetic socket. The attachment unit comprises a body defining an axis and a central opening for selectively receiving the insert. The body carries a plurality of locking elements that are distributed circumferentially about the axis and radially repositionable relative to the axis. A release mechanism is slidably positioned on an outer surface of the body to move the prosthetic attachment system between a locked configuration in which the locking elements are radially repositioned to lock the insert in the central opening of the body and an unlocked configuration in which the insert is released from the central opening.

A quick disconnect mount includes a mounting stud securable to a structure, and a connector securable on the mounting stud. The mounting stud includes at least one circumferential ridge and at least one circumferential trough, and the connector includes a central channel sized to fit over the mounting stud and a locking bar engageable with the circumferential trough.

A release mechanism for releasably securing a releasable structure to a stationary structure, where the mechanism employs release balls that can re-secure the releasable structure to the stationary structure. The release mechanism includes a base portion having three rails extending radially outward from a center of the base portion, and a rotatable portion rotatably mounted to the base portion, where the rotatable portion has a cam indentation. The release balls are positioned between the base portion and the rotatable portion so that one of the release balls is ridable on each of the rails and all of the release balls are positioned within the cam indentation. The cam indentation is configured so that as the rotatable portion is rotated relative to the base portion the cam indentation causes and allows the release balls to move along the rails in unison with each other to hold and release the releasable structure.

The subject device is an adjustable coupling and quick release safety system, both automatic and manual and is applicable at a wide range of applications. It is mainly composed of two elements called “receptacle” (1, 2, 3) and “sphere” (8). The coupling and/or the release are controlled by a spring (5) with adjustable force, the coupling and/or the release can be made for direct pressure between the two elements or manually via a lever (6). The system also allows the angular and rotational movement of the sphere (8) which may however also not to be oscillating or rotating. The current state of the technique involves articulated sphere joints with fixed coupling or with connections of different kind.

Diverting pulley arrangement, more particularly a diverting pulley arrangement of an elevator, which arrangement includes an axle, at least one diverting pulley that rotates while supported on the axle, a faceplate structure, in relation to which and supported by which the diverting pulley is arranged to rotate on the first side of the faceplate structure, which axle is locked so that it does not rotate by the aid of a locking element that moves in relation to the faceplate structure, which locking element is on the second side of the faceplate structure. When it starts to rotate, the end of the axle forces the locking element to displace out of its position and to trip a safety switch.

A locking pin with a locking mechanism (8, 27, 28) that has a guide sleeve (3) that can be attached to a machine part, and a pin (2) connected to an actuator button (6), which passes through a central bore (14) in the actuator button (6), and which can be axially displaced and secured in a hole in the guide sleeve (3) counter to and by means of the force of a compression spring (7) by actuating the actuator button (6), wherein the pin (2) can be brought into at least two locking positions in the guide sleeve (3) by means of the locking mechanism (8, 27, 28) located in the central bore (17), wherein the locking mechanism (8, 27, 28) is sealed in the central bore (14) of the actuator button (6) in the region of a second guide sleeve (12) that is coaxial to the first guide sleeve (3) and connected thereto, and is composed of a locking sleeve (8) secured to the actuator button (6), the sleeve extension (15) of which forms a locking contour (28) in conjunction with a locking recess (27) located in the region of the second guide sleeve (12).

Locking device comprising: a support, a first locking member and a second locking member, the first locking member being mounted on the support and configured to move between a locked position and an unlocked position, an intermediate member movable between a retaining position and a release position, the intermediate member in the retaining position retaining the first locking member in the locked position, and a shape-memory member, the shape-memory member being connected to the intermediate member and configured to move the intermediate member to the release position when the shape-memory member is activated.
