Title: Soundproofing wall having a plurality of box-shaped soundproofing elements which are arranged one beside the other
Inventor: MUELLER WERNER
IPC: E04B1/82
Filed: 1981-06-09
Abstract: In the case of a soundproofing wall constructed from individual soundproofing elements, the gap between neighbouring soundproofing elements is covered by a covering rail held by fastening elements which, at the same time, also fix longitudinal webs, belonging to the soundproofing elements and extending the outer surface thereof, with respect to one another. For this purpose, each fastening element has a clamping device, accessible from the outside, and an inner locking head with locking arms which engage behind the longitudinal webs and are clamped in the direction thereof. In order to obtain a positively locking connection between neighbouring soundproofing elements which is less dependent on the clamping forces, the locking arms have locking protrusions which engage behind protrusions of the soundproofing elements and thus secure, in a positively locking manner, neighbouring soundproofing elements from being drawn apart from one another. By means of a compression spring between the outer surface of the soundproofing elements and a supporting surface of the clamping device, the locking heads which have been pushed through the gap can be turned, transversely to the gap, into their locking position, whereupon, when the compression spring is relieved of pressure, the locking protrusions can engage behind the protrusions and can be braced by means of the clamping device. Even if the clamping device is loosened unintentionally, the mutual position of the soundproofing element remains secured owing to the positively locking engagement.

Abstract: Using a manual rivet head setter (7) (riveter), it is possible, by pivoting a handle lever (13) towards a fixed grip (12), to pull a mandrel (10) inserted in a rivet sleeve (9) through the rivet sleeve (9) to set a rivet head by a process in which a head at the forward end of the mandrel (10) upsets the riveting sleeve (9) and is then torn off. An actuating lever (20) pivotably attached to a housing (11) is pivotably connected at one end to a chuck (14) for gripping the mandrel. The other end of the actuating lever (20) forms an engagement element (30). Pivotably suspended on the grip lever (13) is a pressure element (36) with a serrated edge (38) which enters into engagement with the engagement element (30). A holding arm (40) pivotably suspended on the grip (12) likewise has serrations which engage in the engagement element (30), these latter serrations being formed next to the serrated edge (38) of the pressure element (36) and interacting with it. In the event of repeated actuation of the grip lever (13), the engagement element (30) of the actuating lever (20) is alternately advanced by the pressure element (36) and held by the serrations of the holding arm (40). At the same time, the holding lever (20) performs a movement which pulls back the chuck (14) and sets the rivet head. <IMAGE>

Title: Emergency off switch for electrically controllable underground mining machines
Inventor: GIEBEL GUENTER
IPC: H01H3/02
Filed: 1981-10-29
Abstract: The emergency off switch for electrically controllable underground mining machines contains an isolating switch (2) in a housing (1) and an operating plunger (4), which can be displaced longitudinally and can be pressed into its switched-off position in the housing against the force of a main spring (5) from a switched-on position projecting out of the housing. A displaceable locking sleeve (9) is supported on the outside of the housing, and an auxiliary spring (10) is arranged between said locking sleeve (9) and a mushroom-head end (7) of the operating plunger, which auxiliary spring (10) acts in the same direction as the main spring on the operating plunger and, on the other hand, in the opposite direction presses the locking sleeve from an unlocking position into a locking position. In the region of the movement path of the locking sleeve, the housing has locking balls (11), which can be displaced radially, rest on the smooth circumference of the operating plunger when the latter is in the switched-on position and block the locking sleeve on an inclined abutting surface (12) against movement into the locking position. When the operating plunger is pressed into the switched-off position, the locking balls can be displaced so far radially inwards from the locking sleeve, by means of their abutting surface, into an annular groove (13) in the operating plunger that they release the locking sleeve to move by means of the auxiliary spring into the locking position, in which the locking balls rest on a stop surface (14) of the locking sleeve. <IMAGE>
