Title: Holding device for jib cranes with jib head members
Inventor: POPPKE REINHARD
IPC: B66C23/82
Filed: 1986-11-24
Abstract: The purpose of the invention is to extend the scope of applications of jib cranes with jib head members. The task is to create a holding device for jib head members which will avoid a restriction of the carrying power or the radius of action. The object is achieved by placing a support at the bearing point of the jib head member, and providing draw elements between the support and the jib head member and between the supports and a power element on the main jib. The power element is connected to the crane superstructure via another draw element. The advantage of the device is that there is always moment acting in the direction of the snatch block, thus preventing the jib head member whipping back. An additional advantage is that the power element acts as a recoil safeguard for the jib head member should the load accidentally drop. <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/20
Filed: 1987-01-15
Abstract: Fuel injection nozzle for pilot and main injection with an inwardly opening valve needle (18), the closing spring (22, 64, 86) of which is supported on a piston (30, 80) guided in a cylinder bore (32, 82) and presses the said piston against a valve seat (36) on the entry of a fuel feed line (20, 38) into the cylinder bore (32, 82). After a pilot injection phase, the fuel forces the piston (30, 80) away from the valve seat (36), whereupon fuel flows into the cylinder bore (32, 82) and the rise of the fuel pressure thereby experiences a temporary interruption, producing a marked transition between pilot and main injection phase. According to the invention, the closing spring (22, 64, 86) has a rectangular wire cross-section and is preferably formed by a cylindrical torus (50, 66, 90), in the circumferential surface of which at least one helically running slot (52, 92, 94) is machined. A closing spring manufactured in this way takes up less installation space than a wound closing spring with a circular wire cross-section and can be beneficially formed at the ends. <IMAGE>

Title: Extruded profile pipe for heat exchangers
Inventor: STRAEHLE ROLAND DIPL ING
IPC: F28F1/16
Filed: 1987-02-11
Abstract: An extruded profile pipe for heat exchangers is proposed which has two profile halves which are located one on top of the other with spacing and are connected to one another in a sealed fashion along two outer longitudinal edges. The connection is constructed at least at one longitudinal edge as an internal-pressure-tight, frictionally engaging and/or positively engaging connection which has at the longitudinal edge of one profile half an integrally formed-on, longitudinally extending, essentially groove-shaped receptacle and at the associated longitudinal edge of the other profile half an integrally formed-on, longitudinally extending engagement web which engages in the receptacle and is held tight therein without joining processes. As a result, very thin-walled, lightweight and cost-effective extruded profiles can be used, the two profile halves of which can be connected simply, quickly and cost-effectively without the need for soldering, welding or mechanical connection to produce the finished pipe.

Title: Method for sealing off the subsoil, especially for sealing off the face, in compressed-air driving by means of a bentonite suspension and apparatus for carrying out the method
Inventor: SCHMELZLE PETER M DR ING
IPC: E21D9/06
Filed: 1987-02-18
Abstract: The object on which the invention is based is to provide a method for sealing off the subsoil, especially the face, during compressed-air driving, in which, by spraying a bentonite suspension onto the face, the flow-off of air out of the working space into the subsoil is reduced in comparison with the known method. For this purpose, a bentonite suspension, before being applied to the subsoil, is mixed together with a polymer-containing additive, in such a way that its stiffness, tackiness and toughness are increased. The apparatus used is a so-called "static mixer" and discharge nozzles which have helices narrowing in the direction of flow. One sector of use is the sealing-off of the face in compressed-air driving in underground mining.

Title: Method for echo suppression for a hybrid circuit
Inventor: TRICK ULRICH DIPL ING
IPC: H04B3/23
Filed: 1987-06-12
Abstract: In a method for echo suppression for a hybrid circuit used to connect a four-wire line to a two-wire line, data signals passing from the incoming four-wire arm onto the outgoing four-wire arm as a result of the imperfect balancing of the hybrid circuit being corrected by means of a corresponding correction signal, first a positive and then a negative test pulse are injected into the four-wire input arm of the hybrid circuit and the echo signals occurring on the four-wire output arm of the hybrid circuit are evaluated. A mean value is formed from the two synchronous samples of the echo signals following inversion of the echo signal generated by the negative test pulse and this mean value is stored in a coefficient memory. The correction signal is then calculated with the aid of the contents of the coefficient memory.

Title: Filter housing for gas turbines and industrial dedusters composed of a universally usable module frame system with horizontally arranged filter cartridges and vertically downwards flowing intake air stream for reinforcing the cleaning effect and for the discharge of dust particles removed by pulses
Inventor: NOTHDURFT HENNING DR
IPC: B01D46/00
Filed: 1987-07-07
Abstract: The invention relates to a module frame system for filter cartridge units matched to a standard filter frame dimension. The module frames can be assembled to form filter housing frames of any size. The filter cartridges are arranged diagonally offset from the module frame. As a result, when the filter cartridges are cleaned, the dust is transported in the manner of a cascade in the direction of the dust collection hopper. A further advantage of the invention is that, owing to the module frame system, existing filter plants can be retrofitted by a self-cleanable filter system without problem. Moreover, the cartridge filter units according to the invention can be equipped with standard filter systems, prefilters and secondary filters. Complex conversion and construction work is dispensed with.

Title: Method for obtaining a phase error signal, and an arrangement for this purpose
Inventor: HEICHLER JOHANNES DIPL ING
IPC: H03M13/23
Filed: 1987-07-24
Abstract: In order to obtain a phase-error signal from a convolution code signal for synchronisation purposes, the difference is formed between the minimum and maximum path metric. The magnitude and change with respect to time of this difference metric (DELTA-M) are evaluated in terms of magnitude and mathematical sign (SUBIII, SUBII). Values derived from the difference metric are subsequently added up or subtracted (ADD/SUB). If the change in the difference metric with respect to time is positive, a previously defined magnitude is subtracted from a current magnitude of the summation. If, in contrast, the change with respect to time is negative, the complement of a previously defined magnitude is added to the current magnitude of the summation. If the summation exceeds a threshold value (THRI), a phase-error signal (FAIL) is emitted (Figure 3). <IMAGE>

Title: Clutch for changing operating conditions, in particular a two-mass flywheel
Inventor: HANKE WOLFGANG
IPC: F16F15/134
Filed: 1988-02-26
Abstract: The invention relates to a clutch for changing operating conditions, in particular a two-mass flywheel for mounting on an internal combustion engine, having two clutch halves, which are connected via elastic elements for the transmission of a torque. Provided in the clutch are two friction elements, one on each of the two clutch halves, and these rub against one another and hence cause frictional damping. According to the invention, the damping force is varied by varying the contour of the frictional surface for one of the friction elements over the angle of rotation. A built-in spring is thereby subjected to differing prestresses, making possible adaptation of the frictional damping to the operating requirements of the engine concerned. In a special development of the invention, hydraulic damping that can be varied over the angle of rotation in a displacement chamber is furthermore possible.
