Title: Method for exchanging switching signals between telephone switching systems connected together as master and satellite stations, particularly private branch exchanges
Inventor: SCHMIDT HEINRICH
IPC: H04M7/14
Filed: 1985-02-27
Abstract: In the exchange of switching signals, carried out by means of modems, between telephone switching systems connected together as master and satellite stations, particularly private branch exchanges, the exchange of switching signals is initiated differently depending on the state of the connection. In the idle state, a begin-to-send signal is applied directly to the line at the beginning of the exchange of switching signals, which determines the direction of transmission. This is followed by a datablock producing the readiness to receive switching signals, the structure of which does not have any information content and is designed in such a manner that no simulation by voice is possible. In the call state, the answer signal is preceded by a 50-Hz signal resulting in the connection of the modem. This measure is used for eliminating false simulation of information initiating an exchange of switching signals. The data blocks sent after that contain special data words which specify the manner in which the remainder of the data block is divided up and which type of switching information is contained in the further data words. In addition, the number of data words or the number of data blocks overall which constitute an identical information can be specified in a data word.

Title: Road train
Inventor: SCHMITZ PETER DIPL ING
IPC: B62D13/00
Filed: 1985-09-13
Abstract: A road train, consisting of traction engine and trailer which conveys a continuous container is described. The container is connected to the traction engine via a king pin and to the trailer via a bearing which permits a relative movement between container and trailer, the trailer being connected to the traction engine via the trailer coupling of the traction engine, via a forked drawbar, a pivot point about a vertical axis and a towbar which, in turn, is connected to the trailer so as to be capable of pivoting about a horizontal axis. In this case, the traction forces from the traction engine to the trailer are transmitted via the forked drawbar, so that, when going round a bend, the trailer can move forwards with respect to the container and the cornering properties of the road train are considerably improved.

Title: Stabilised flocculant and precipitant for water prepurification
Inventor: WILKE HERBERT DR ING
IPC: C02F1/52
Filed: 1986-02-01
Abstract: The present invention "stabilised flocculant and precipitant for water prepurification" relates to a process for improving the formulation ability, storability, meterability and reactivity of hygroscopic flocculants for water treatment. This is achieved by homogeneously distributing a highly concentrated solution of the flocculant in absorbent, large-surface-area, granular inert carriers.   If kieselguhrs are chosen as these, the application form according to the invention gains a further series of advantageous properties which favourably affect the water purification, e.g. by hazard-free application, short flocculation and sedimentation times, by an intensified adsorption effect and by improved separation behaviour on decantation or filtration.

Patent DE-3606514-A1 (DE)
Inventor: GASSNER THEO
IPC: B25C1/18
Filed: 1986-02-28
Abstract: An explosive powder charge operated fastening member driving tool has a muzzle part which can be locked within and released and removed from the tool housing by rotational movement and axial movement relative to the housing. When the tool is not ready to be fired, a contact pressure sensor projects from the front end of the muzzle part. By pressing the sensor opposite to the firing direction it compresses a firing mechanism spring and the tool is ready to be fired. Stop elements are provided on the muzzle part and stop surfaces are located on the tool housing. When the muzzle part is in the unlocked condition, the stop elements can abut the stop surfaces and block the displacement of the contact pressure sensor preventing it from compressing the firing spring mechanism so that the driving tool cannot be placed in the ready-to-fire condition.

Title: Pliers for assembly purposes
Inventor: SCHWALM DIETER
IPC: B25B7/12
Filed: 1986-05-24
Abstract: In these pliers, one of the two handles (1, 2) is subdivided into an inner shorter handle part (17) and an outer longer handle part (18) and these two handle parts are connected to one another in articulated fashion by means of a second articulation joint having an articulation pin (20) which is axially parallel to the (first) articulation joint of the pliers. A chain wheel (21) and a ratchet wheel (22), connected to the latter so as to be fixed in terms of rotation, with outer toothing are rotatably mounted, axially next to one another, on said articulation pin (20). The chain wheel (21) engages in a chain (24), e.g. a flat link articulated chain, which is fixed by one end to the opposite handle (1), is guided from here externally around the chain wheel (21), extends further along the outer handle part (18) and is connected by its other end resiliently to the handle part (18). Furthermore, a driving detent (29), capable of engaging in the ratchet wheel (22) and being subjected to the action of a spring (32), is mounted on the outer handle part (18) in such a way that, after a preceding opening movement of the outer handle part (18), it sets the ratchet wheel (22) and hence the chain wheel (21) in rotation in the subsequent closing movement, as a result of which the chain wheel (21) rolls on the chain (24). By this additional lever arrangement, the transmission ratio of the pliers is considerably increased. A six-fold increase or more is achieveable, while maintaining the usual dimensions. <IMAGE>

IPC: F28D1/02
Filed: 1986-05-27
Abstract: The subject-matter of the invention is a novel radiator segment and an arrangement of these segments to form a combination radiator for motor vehicles. The radiator segment is constructed in this case in one piece which consists of an extruded profile (1) made from aluminium and having at least one longitudinal bore (2) as a channel for the medium, and of lamellae (4) extending in the longitudinal direction of the profile (1). It can be combined with at least one other radiator segment. The bounding plate (5) of one segment rests congruently on the bounding plate (6) of the other segment. The longitudinal bores (2), respectively of the same diameter, are connected to one another in the segments to form a channel passing through the segments by means of aluminium tube bends (7) in the shape of circular segments. The segments are interlocked via the insertion groove (16) of one segment and the inserted insertion ridge (17) of the other segment. The advantages of this radiator which consists of a plurality of segments reside in that a plurality of cooling circuits are available. Use is made of the heat dissipated by the engine into the cooling medium. Another advantage is that both the radiator and the individual segments are of simple construction and are simple to produce. <IMAGE>
