Patent DE-2829015-A1 (DE)
Title: Automatic connector for electric cable to coupling contacts - uses indexing rotary plate with peripheral holders of cable core ends and has compression device for securing ends in holders
Inventor: SCHIRMER KARL ING GRAD
IPC: H01R43/28
Filed: 1978-07-01
Abstract: The contacts are mounted on an insulating support in a line connector. The individual conductors are automatically preformed, in order to correspond to the contact positions, as well as to be firmly and conductively connected to the contacts. For this purpose an indexing rotary plate (2) is mounted via its horizontal axis in a work table. The plate periphery carries several holders (5) for retaining the line ends (11). The table contains an inserting device (18), through which the cable line is pressed in correct position in one holder, after all conductors of the cable have been correctly aligned. Above the table are located forming station s (6-8) along the plate periphery into which the line ends are inserted during the indexing of the plate, these stations performing insulation stripping, position checking and connecting proper.
Patent DE-2833184-A1 (DE)
Title: Push-button assembly with common contact rail - embodying integral U=shaped return-springs for push-buttons to reduce number of parts
Inventor: LABUDE WOLFGANG ING GRAD
IPC: H03J1/06
Filed: 1978-07-28
Abstract: The push-button assembly has a return spring for each button that also acts as an integral part of the contact rail. The contact rail has a connection part- with a solder point passing out of the casing- and a spring part comprising as many springs as there are push-buttons. The spring part is U-shaped and connected at one end to the connection part and at its other, free end lies on the contact piece of its push-button when the latter is on, thereby providing the wanted spring action. The advantage lies in fewer components and easy use.

Title: Industrial boiler with motor-generator - uses back-pressure steam turbine to drive air pump supplying boiler
Inventor: WIESER RUDOLF DR
IPC: F22B7/14
Filed: 1979-05-12
Abstract: The industrial boiler has at least one of its air pumps driven by an electromotor or motor/generator and by a back-pressure steam turbine. When the boiler system is in normal operation the electricity produced by the motor/generator is supplied to the mains network. The boiler is high-speed and a 'cold' flue-gas velocity of at least 15 Nm/sec. (pref. 20-40 Nm/sec.) prevails at its heating surfaces. The static draught loss on the flue gas side at rated loading is at least 0.04 bar (pref. greater than 0.1 bar). The advantage lies in increased efficiency due to the use of a motor/generator to produce electrical energy in back-pressure mode.

Title: Plastics bag making machine bundle forming mechanism - has stacking table reciprocated under welding needles above end of collector conveyor
Inventor: LAUMEN EGON
IPC: B31B70/00
Filed: 1979-10-12
Abstract: The stacking mechanism for a plastics bag making machine includes welding needles (12) which form the bags into a welded pack before being deposited onto a take-off conveyor (10). Tubular plastics film (1) is fed horizontally towards two welding jaws (4) with a cutter (5) between them.

Title: Process for producing fibre mat-reinforced plastic articles from moulded parts
Inventor: RUDOLF ARTUR
IPC: B29C70/48
Filed: 1981-01-15
Abstract: The invention relates to a process for producing fibre mat-reinforced plastic moulded parts and, to increase the moulded part strength and material homogeneity, proposes to increase the volume proportion of the fibre material as far as the optimum in that a preform of pressed fibre material is produced in that individual mat blanks are laid one on top of the other in a compression mould and next their fibre connection points are softened, then the complete mat blank assembly is pressed to a fraction of its thickness and to a shape corresponding to the moulded part with the compressive force being maintained until the fibre connection points are solidified again, subsequently to which these preforms are impregnated with liquid resin within a mould and encapsulated. In an improvement of the process (according to the main application P 3041020.9) an externally loaded film mould wall (10) is present which remains compression-loaded at least until complete solidification of the liquid resin sucked in. <IMAGE>

Title: Method for improving the response time characteristic of process computers
Inventor: TEMPELMEIER THEODOR DR
IPC: G06F9/48
Filed: 1981-02-16
Abstract: This invention is in the field of the design and construction of process computers. The problem that the execution of the operating system kernel leads to a deterioration in the response time characteristic and the reaction time characteristic which is no longer tolerable is solved by the following design and organisational measures: a separate additional processor which is exclusively available for the execution of the operating system services is used for the operating system kernel. The actual process computer is thus (almost completely) independent of the execution of the operating system and is completely available for the user computing processes. This method can be used for improving the time characteristic in all process computers with an operating system which are to be newly designed or newly built.
