Title: Process and arrangement for controlling a telephone private branch exchange
Inventor: WEBER DIETMAR
IPC: H04Q3/62
Filed: 1987-09-23
Abstract: The invention relates to a process and an arrangement for controlling a telephone private branch exchange. The telephone private branch exchange has a switching computer (VR), a switching matrix (KF), extensions (T1...Tn) connected via interfaces (IF), memory devices (SPT1...SPTn) and timing elements (CLT1...CLTn), which are assigned to the switching computer (VR) and are extension-specific, and also a memory (T), which contains values (Wi) which are likewise assigned to the switching computer (VR) and are actuation-specific. Upon first-time actuation of an exchange (T1) by lifting the telephone receiver except when there is incoming traffic or by triggering an instruction directed at the computer (VR), the timing element (CLT1) is activated for a first period (t1). Upon each actuation of the extension (T1) within (t1), the computer (VR) stores an actuation-specific individual value (Wi) in the memory device (SPT1), forms the sum of the individual values (Wi+Wi-1) and compares this with a limit value (G). Upon reaching or exceeding the limit value (G), the exchange is blocked for a period (t2) or released only for incoming traffic. The values (Wi) correspond to the computer capacity called upon by the respective actuations. The invention prevents any improper actuation of extensions. <IMAGE>
Patent DE-3732744-A1 (DE)
Title: Cluster munition (submunition carrier projectile) having submunitions
Inventor: WOLLENBERG HARALD
IPC: F42B12/60
Filed: 1987-09-29
Abstract: Until now, submunitions which can be ejected from a cluster munition required adjustable means for setting the detonation separation for the shaped charge to achieve an optimum effect in the target zone, as a result of which, however, it is not possible to prevent the shaped-charge diameter being reduced or the penetration performance of the shaped charge being adversely affected as a result of the adjusting mechanism. The invention avoids these measures which have an adverse effect on performance by using the fillers (which are arranged between the submunitions within the cluster munition) as detonation separators 7. The fillers can be attached, for example by a bonded or riveted joint, directly during submunition production to the front outer wall 8 of the casing 3 of each submunition 2 and in consequence enable simple construction of the detonation separators 7 in order to achieve an optimum detonation separation "a" projecting beyond the submunition 2. <IMAGE>

Patent DE-3831129-A1 (DE)
Inventor: HEHL KARL
IPC: B29C45/17
Filed: 1988-09-13
Abstract: The plastic injection-moulding machine has a separator which is arranged underneath the injection mould and has a pivotal plate (36). The latter can be pivoted into two inclined positions (acceptable part position and unacceptable part position). In the acceptable part position, the plate (36) terminates above a device (conveyor belt 17) receiving the moulded parts (73). In the unacceptable part position, the plate (36) terminates above a size reduction device. The latter comprises a cutting mechanism (G) which can be removed as a structural unit from the machine frame (M). It further comprises a motor- transmission block, which is arranged outside the vertical projection of the cutting mechanism (G). The separator can be moved as a structural unit (separating unit E) from the machine frame. By such a design, better allowance can be made for the different financial capabilities and different production processes of potential customers. The injection-moulding machine can be supplied in various stages of automation, which can be converted one into the other without requiring any great assembly work. Very little work is also required for removing the simply designed cutting mechanism from the machine frame for exchange, repair or cleaning.

Title: Measuring cell configuration for determining the electrokinetic streaming potential on substrates which are plate-shaped or capable of being coated
Inventor: TRAUZEDDEL RAINER PROF DR SC N
IPC: G01N27/60
Filed: 1988-12-05
Abstract: The invention relates to the field of electrokinetic interaction processes. A possible field of application for the invention is the routine, reproducible determination of electrokinetic streaming potentials in all processes in which planar materials are contacted by fluid systems.

IPC: B27B5/06
Filed: 1989-04-10
Abstract: A method for the program controlled longitudinal and transverse cutting-up of plates is described, in which from at least one plate, following an edging cut, an edge strip is detached by a further cut and the remaining plate is then cut up parallel to this cut into a plurality of strip-shaped plate sections, whereupon edge strips and plate sections are conveyed further and cut up transversely relative to the cuts made. 
<??>According to the invention, edge strips produced at the longitudinal cutting-up saw are first collected and fed together to the transverse cutting-up saw only after a predetermined number of remaining plates have been cut up. Consequently, the edge strips produced on cutting up a number of plates can be cut up in one operation, resulting in a considerable increase in efficiency.

Title: Use of inertia force of mass to produce energy - involves accelerating mass and then using its kinetic energy
Inventor: EWERT KLAUS-DIETER
IPC: F01D1/32
Filed: 1989-10-27
Abstract: The energy transfer system use inertia forces of masses which are either moving linearly or are rotating, in alteration with a gravitational field in order to convert these forces into usable energy. Accelerating a mass (1) by an impulsive force results in a linearly increasing velocity. After reaching a pre-determined velocity the kinetic energy of the mass, which is proportional to the square of the velocity of the mass, is converted into work. It is claimed that this work is greater than the work done in accelerating the mass, the extra work being derived from the gravitational field. USE - Utilisation of the energy of the gravitiational field.
