Title: Process for the production of closed portion packs
Inventor: REST GUENTHER
IPC: B65B9/04
Filed: 1981-03-24
Abstract: The invention relates to a process for the production of filled closed portion packs, especially for foodstuffs, container columns being shaped by deep-drawing from an endless plastic foil, being filled in a composite structure and being covered with an endless metal foil, whereupon the plastic foil and the metal foil are sealed together with one another in the region of the container contour, and finally the containers being separated from one another by being punched out. In known processes, during sealing the plastic foil and the metal foil are also welded together with one another outside the region of the container. A re-treatment of the waste consequently became impossible. The object on which the invention is based is to design a process and the apparatus for carrying it out, in such a way that an economical processing of the foil residues which occur becomes possible. This is made possible, according to the invention, in that sealing takes place solely in the immediate edge region of the container orifices, during the punching-out of the containers the sealing faces are also punched out completely, furthermore lattices are left behind in the foils during the punching-out, and the foils are separated for re-treatment.

Title: Dam-building materials for underground mining
Inventor: HOELTER HEINZ ING GRAD
IPC: C04B28/02
Filed: 1981-04-04
Abstract: The subject of the parent application P 3,109,879.7 is a process for the disposal of waste products arising downstream of coal-fired power stations and for the utilisation thereof, using waste heat from the power station for the manufacture of dam-building materials or the like for underground mining. The waste products to be disposed of, such as filter ash and flue gas desulphurisation gypsum, are mixed with the wet and/or dried calcium chloride from the flue gas scrubbing and used with further addition of further binders and hardeners, such as cement, as dam-building material and/or backfill material for underground mining. It has now been found according to the invention that an addition of about 2-3% of calcium chloride dihydrate (CaCl2 . 2H2O) to the said mixture results in a special sealant with a high setting rate and high strength. The following composition has proved to be particularly suitable:     60-65% from the flue gas desulphurisation plant, 15-20% of filter ash and/or slag from the coal-fired power station boiler and filter area, about   10-15% of anhydrite and/or cement, and 2.5% of calcium chloride dihydrate.
Patent DE-3117446-A1 (DE)
Title: Measuring element for determining the internal pressure of fuel rods
Inventor: DECKERS HANS
IPC: G01L9/00
Filed: 1981-05-02
Abstract: The invention relates to a measuring element for determining the internal pressure of fuel rods, which are closed by means of end plugs and contain a fission gas plenum (space). It is characterised in that there is arranged inside the fuel rod a pressure cell which contains a magnetic or magnetically influenceable core whose position can be varied relative to an outer end face of an end plug of the fuel rod. According to the invention, preference is given to the concept of determining the internal pressure of the rod. It is necessary in this case for each fuel rod to contain a pressure cell immediately above the lower end plug or connected thereto. Said cell can consist of a closed bellows in which a ferrite core is axially displaced when there is a rise in the internal pressure of the fuel rod. When the pressure drops, the core returns to its initial position, which is precisely defined by a stop surface. In order to monitor rod defects, the special measuring device is used to scan the position of the soft iron core relative to the lower edge of the end plug.

Title: Torque-limited clutch
Inventor: KILWIN THOMAS C
IPC: F16D7/08
Filed: 1981-05-21
Abstract: A torque-limited clutch which is suitable for use with a further shaft, a flange or the rotary plate of an indexing-table-type machine system or the like comprises a driving element (2) and a driven element (3), which are connected to one another via bearings. The driving element has a flange (6) which extends integrally from one of its ends and has grooves (7) which accommodate a row of ball detent elements (8). Springs (24) and adjusting nuts (15) press against the detent elements so as to press them into engagement with bearing seats (9) formed on a rotatable element (11) integrally connected to the driven element (3). A holding means (12) is connected to the rotatable element and extends concentrically along the length of the driving element (2). The holding means holds the adjusting screws and the springs and furthermore provides a casing for the operating parts of the clutch, keeping them free from dirt during the normal length of their life and running time. Various running rings (25, 27) are preloaded against the ball detent elements and ensure uniform distribution of the pressure against the detent elements in their set relationship with the rotatable element on the driving element. They furthermore allow displacement of the detent elements when these disengage from the bearing seats during the separation of the clutch. A multiplicity of rods (30) and a displaceable plate (29) are connected to the running rings and, during the separation of the clutch, undergo a displacement, allowing a microswitch or the like to be actuated in order to switch off the machine system connected when an excessive torque is applied and a separation of the clutch occurs.   <IMAGE>

Title: Circuit arrangement for setting up connections which are free of charge to the calling subscriber
Inventor: SCHMID ADOLF ING GRAD
IPC: H04M15/08
Filed: 1981-06-13
Abstract: To set up connections which are free of charge to the calling subscriber in a hierarchically structured telephone switching system comprising exchanges with step-by-step connection set-up and exchanges operating with a memory-programmed controller, a local exchange (OVST) operating with a programmed controller is connected to the central exchange (ZVST) in such a way that the number characterising the pre-defined subscriber connections can be converted in the local exchange (OVST) into the telephone number of the allocated subscriber connection and the charge debited to the called subscriber connection can be calculated. The continuing connection is returned to the central exchange (ZVST) so that all subscriber connections can be reached from there. Both pairs of speech wires bypass the local exchange (OVST) in order to prevent additional attenuation.

Title: Measuring instrument for power (output performance) testing of motor vehicle internal-combustion engines
Inventor: GERSTMAYR FRITZ
IPC: G01L3/24
Filed: 1981-06-30
Abstract: A power test is clearly the best test method after work on adjustment, repair and tuning for a motor vehicle internal-combustion engine and partly for fault diagnosis. Because of their complicated design, the power test stands presently employed are very expensive and are therefore profitably used only in large repair shops. The object of the invention is to provide a device which permits power tests on motor vehicle internal-combustion engines in conjunction with low procurement costs, ease of manipulation and satisfactory accuracy. This object is achieved using a measuring device which is placed in the interior of the vehicle and has a stop watch (7) and an engine speed measuring instrument (1), chiefly with an integrated circuit (2) for driving LED rows (3). The outputs of this IC are connected to a thyristor or IC (6) which starts or stops the stop watch when the motor vehicle accelerates and the engine speeds set at the switches are reached. Reduced or increased power of the engine can be determined immediately by comparing the time read off with the desired time of the vehicle type. <IMAGE>
