Title: Stool
Inventor: RAU SIEGFRIED
IPC: A47C9/02
Filed: 1982-03-05
Abstract: A stool, which consists of a seat surface supported via a support beam on a support part provided with feet, the support beam being subjected to the effect of a restoring force and being limitedly displaceable counter to said force relative to the support part, is to be improved to the effect that it also allows appreciable oscillating movements without the fear of tipping. This is achieved according to the invention in that the support beam of the stool has on its end face on the support part side at least one support element, whose support surface lies above and inside the resting surfaces of the feet of the support part in the unloaded state of the stool and forms an additional support of the seat surface in the loaded state.
Patent DE-3209306-A1 (DE)
Title: Pipe bushing
Inventor: QUECK CLAUS DIPL ING
IPC: F16L5/02
Filed: 1982-03-15
Abstract: The invention relates to a pipe bushing in which a pipe passes through a wall opening in a sealing manner. The pipe can move slightly with respect to the wall so that account must be taken of this to a certain extent for the seal. To avoid having to use a sealing means, as is normal, between the wall opening and the pipe, which sealing means at the same time supports the pipe, a sleeve is used according to the invention, between the wall and the pipe, which sleeve is held in a completely stress-free manner by virtue of its special construction. It consists of a cylindrical section of approximately the same diameter as the pipe external diameter, and of a truncated-conical section which is adjacent thereto and is attached to the wall by means of an annular flange. The supporting function of the pipe is taken over by a shell which is fitted specifically for this purpose, with respect to which the pipe can be displaced.

Title: Arrangement for connecting sheet-metal tubes
Inventor: BETZ MANFRED
IPC: F16L27/10
Filed: 1982-03-17
Abstract: Large-volume sheet-metal tubes are used especially in air-conditioning systems, which tubes are assembled from shell parts which are connected to one another at their edges by folds which extend in the longitudinal direction of the tubes and project outwards from the tube surface. In order to connect such tubes, the invention provides that an annular connecting piece is arranged between the ends of the tubes which are to be connected to one another, and the tubes are pressed against the connecting piece at their ends, by means of clamping elements which engage on the folds of the tubes, which folds are arranged in an aligned manner, to be precise engaging in holes, especially with hook-shaped ends, which holes are incorporated in the folds for this purpose. It is possible to use as connecting piece in particular bodies which have grooves facing the tube ends, such as sheet-metal profiles and sealing strips consisting of elastic materials. The clamping elements can be constructed in particular in the manner of turnbuckles or beer-bottle closures.
Patent DE-3210015-A1 (DE)
Title: Optical measuring instrument for measuring railway lines
Inventor: PLOETSCHER KLAUS
IPC: E01B35/00
Filed: 1982-03-19
Abstract: The position of railway lines, particularly in curves, has to be checked from time to time for direction and level with respect to their desired position. Depending on the results of the check, correction measures are then initiated. The desired position of the lines is established in terms of direction and level by the railway surveying service, starting from reference points (bolts on the catenary support, or similar). Curves are measured by determining rises between the centre of the line and a longitudinal chord (Fig. 4). The level is determined by 3-point measurement on a longitudinal chord (Fig. 6). The reference edge for the direction is the gauge line of the line of rails lying outside in the cant. The reference edge for the level is the rail upper edge of the track lying inside in the cant. Both measurements previously had to be carried out separately. The measuring instrument consists of an optical system stand with mounted sighting optics and a stand for the target with mounted graduated rods. By transmitting the level of the line of rails situated below in the cant onto the optical system holder or the graduated rod holder, it is now possible to determine the lateral position and level in one operation. <IMAGE>

Title: Process for feeding a yarn to a friction false twister and device for carrying out the process
Inventor: DAMMANN PETER DIPL ING
IPC: D02G1/08
Filed: 1982-04-07
Abstract: What is proposed is a process for feeding a yarn (9) to a friction false twister having two frictional surfaces which are moved relative to one another and form between them a nip for the yarn and of which at least one of the frictional surfaces is formed on a flexurally soft disc or on a band run and is pressed down resiliently from its rear side by a press-down device (100). According to the invention, the press-down ram (130) of the press-down device (100) is pressed down, during the feeding of the yarn, with a pressure force reduced substantially in relation to the normal value, so that the false-twist level and the inherent conveyance of the friction false twister are greatly reduced. Consequently, the twisting of the yarn decreases and the yarn tension falls. The risk of a yarn break is avoided even where fine linear densities are concerned. In addition to the process, devices for carrying out the process are proposed. <IMAGE>

Title: Method and apparatus for covering swimming pools
Inventor: MUELLER PAUL
IPC: E04H4/10
Filed: 1982-04-23
Abstract: The invention relates to a method and an apparatus for the automatic covering and uncovering of water surfaces of swimming pools. The method requires only a minimum of effort for the secure guidance of the covering element during the movement phase, for structural measures on the body of the pool and for operation of the covering apparatus. It is suitable in particular for the retrofitting of existing baths with covering apparatuses. To carry out the method, there is provided, on the pool edge side opposite the winding apparatus (3) for the covering element (4), a shaft (9) arranged in the pool-surrounding passage and intended for receiving a pulling-rope drive apparatus, consisting of drive motor (10), coupling and gearing part (11) and rope drum (12). The drive apparatus can be lifted by opening the shaft cover (13) such that a deflection-free rope connection between rope drum (12) and the covering element (4a) is provided. To cover the water surface, the rope (14) is connected to the covering element (4) and automatically pulled over the water surface after switching on the motor (10). A rubbing contact of the covering element with the pool edge (8) is prevented in this process, both on covering and uncovering the pool, so as to avoid wear. <IMAGE>

Title: Setting machine for the positive attachment, in particular rivet attachment of haberdashery articles, such as press stud parts
Inventor: KAISER GUNTER DR
IPC: A41H37/04
Filed: 1982-07-08
Abstract: In a setting device for the positive attachment of a group of haberdashery articles, such as press stud parts, to a web, tools are used which are arranged with lifting movement relative to one another and which are intended to carry out the deformation work at defined attachment points on the web. For a reliable and simple device which can conveniently be adjusted to different intervals of the attachment points, a slide is used which is provided with a longitudinally running transport rod and has clamps at both ends for tensioning a strip of the web having the desired attachment points and lying freely between them in alignment with the operating direction of the upper and lower tools. A material drawing-in apparatus can then be used as transporting means, which apparatus is constructed with an advancing clamp with lifting movement and a stationary holding clamp and acts in a clamping manner on the transporting rod. A new web can thus be clamped in each extreme position of the slide and processed without delay because the slide is returned stepwise into the respective other extreme position by simple reversal of the direction of the operating and idle phase of the advancing clamp. An adjusting unit is activated in at least one extreme position of the slide and adjusts the slide into its prescribed position.

Title: Device for transporting patients, in particular a stretcher
Inventor: SCHUMANN ERWIN
IPC: A61G1/048
Filed: 1982-12-10
Abstract: In devices for transporting patients, in particular stretchers, with lateral, longitudinally extending hollow-profile bars, on which the supporting material is secured along its longitudinal edges and on which carrying handles are arranged, the carrying handles are designed in such a way that they can be pushed individually into the hollow-profile bars so that they do not get in the way when not in use. When the carrying handles are in the withdrawn state, they currently retain their displaceability however, so that they may inadvertently be pushed into the hollow-profile bars and thus bring about a risk of injury. In order to provide a device for transporting patients, in which this disadvantage is eliminated, and in which the carrying handles cannot be pushed in inadvertently, in other words their working position is secured, it is proposed to provide between each carrying handle and the relevant hollow-profile bar a detachable locking arrangement which is operative when the carrying handle is in the withdrawn position.

Patent DE-3304302-A1 (DE)
Title: Electrically operated unit for driving in attachment means
Inventor: MUELLER ERWIN
IPC: H01F7/08
Filed: 1983-02-09
Abstract: In the case of relatively long fastening means it is often difficult to apply sufficient force to shear off a fastening means, for example a nail, with an electrically operated unit using the pinion-type cutter. As the pinion-type cutter rests directly on the front attachment means which projects into the ejection channel before the start of a drive-in stroke, the armature does not have sufficient force when an electrical magnetising pulse is emitted to sever the attachment means. The present design circumvents this disadvantage in that the pinion-type cutter is connected to the armature so as to be movable in the direction of movement. As a result of this, sufficient kinetic energy is available to the pinon-type cutter for severing relatively large attachment means, especially nails of the longer sort.
