Patent DE-3621751-A1 (DE)
Title: Pushbutton-actuable espagnolette lock
Inventor: MANZ SIEGFRIED
IPC: E05B1/00
Filed: 1986-06-28
Abstract: The invention relates to an espagnolette lock, as a result of the accoutrements of which the pushbolt and the espagnolettes are moved into the desired position, without the use of a key, by means of a pushbutton-like handle. The sprung pushbutton is connected to the push-bolt via a toggle joint, in such a way that the joint pin is received in a slot formed on obliquely and transmits lifting forces into the two joint arms as a result of the actuation of the pushbutton. The joint arms on the one hand are held rotationally movably at a fixed point and on the other hand displace the push-bolt out of the open position into the closed position. The lifting travel of the pushbutton and therefore the push of the bolt are limited in the opened position of the lock by stops in the pushbutton and lock cover. The fixing of the lock position is achieved by means of a shift slot which is formed in the pushbutton and into which penetrates a control part mounted in a lock-cover extension. The shift slot causes the retention and release of the pushbutton. As additional locking, a lock cylinder, by means of which the pushbutton can be blocked in the locking position, can be inserted into the pushbutton. <IMAGE>

Patent DE-3731818-A1 (DE)
Inventor: BERGNER ARNDT
IPC: F16B13/08
Filed: 1987-09-22
Abstract: The expansion dowel, consisting of an anchor bolt (1) and an expansion sleeve (2), is radially enlarged by driving the expansion sleeve (2) onto a broadening (1e) of the anchor bolt (1), and is anchored in the drilled hole. The broadening (1e), designed as a concave bulge, results in an increasing conicity in the insertion direction, as a result of which the subsequent expansion of the expansion dowel is limited. Cutting teeth (2d, 2e, 2f), which are arranged on the front end region of the expansion sleeve (2) and have a saw-tooth-shaped profile, deposit a proportion of the retention material on the wall of the drilled hole, when the expansion sleeve is driven forward, and thus create an undercut. In order to attain easier deformability, the expansion sleeve (2) is provided on its outer side with a ring slot (2g) in the region adjacent to the cutting teeth (2d, 2e, 2f) in the direction opposite to the insertion direction.

Title: Method for mutually bonding optical waveguides to form a ribbon cable
Inventor: SCHUETTEN DAGMAR
IPC: G02B6/44
Filed: 1987-10-01
Abstract: The invention relates to a method for mutually bonding optical waveguides (LWL) to form a ribbon cable, in which a plurality of optical waveguides are drawn through a container filled with adhesive, are then made to be parallel and adjacent by means of a calibrating arrangement, and are finally passed in this ribbon cable configuration through a curing device for hardening the adhesive. The optical waveguides are placed directly side by side in a simple manner by passing the optical waveguides (1) which are wetted with liquid adhesive through a flat nozzle (4) which has an essentially rectangular passage opening. This passage opening is formed by two parallel surfaces (12, 15) which are arranged with respect to each other at the distance of the maximum tolerance dimension of the thickness of the optical waveguides, by one side surface (16) running firmly to the parallel surfaces, and by an opposite side surface (17) which is part of a slide (13) which can be displaced in the direction of the firm side surface (16), and which is pushed with such a contact-pressure force (springs 14) against the optical waveguides (1) which are drawn through the exit nozzle (4) that all adjacent optical waveguides (1) are in direct contact. <IMAGE>

Title: Method for mixing ammonia into a flue gas stream
Inventor: BRANDS HEINZ-JOSEF
IPC: B01D53/86
Filed: 1988-01-13
Abstract: The addition of ammonia to a flue gas stream has previously been carried out by taking off liquid ammonia from a liquid gas tank and converting it into the gas phase in an evaporator and mixing the ammonia vapour into the flue gas stream. According to the invention, an aqueous ammonia solution is sprayed into a carrier gas stream and evaporated therein and the carrier gas stream, mixed with the ammonia and water vapour, is added again to the main stream. The carrier gas stream used is a part-stream branched off from the main stream of the flue gas or a preheated fresh air stream or a dry steam stream. The problems which are associated with the transport, storage and handling of liquid ammonia are thus bypassed without the presence of the additional water having a disadvantageous effect. The method is suitable for use in connection with the denitration of flue gases of large scale furnaces.
