Title: Moulding of packaging containers from preheated sheet - with air blown onto sheet to achieve more uniform cooling
Inventor: MEDWED EMMERICH
IPC: B29C51/04
Filed: 1980-03-14
Abstract: The moulding of containers from a foil or sheet uses a moulding plunger which presses on the preheated foil after it has been clamped along at least two, more specifically four sides. The plunger is so shaped that its peripheral regions press the heated foil before the central region reaches the foil. Air is blown onto the peripheral regions of the foil which adjoin the central region. Preferably, the air is blown into the regions of the foil which will form the corners of the vessel. In the prior art the most heavily stretched regions are at and near the corners but at the same time these are most highly cooled regions, by comparison with the centre, due to the action of the plunger. By blowing air onto the foil in these regions so that is spreads across the foil and leaves at the centre, more uniform cooling of the foil is achieved with the result that the stretching of the foil during the moulding operation becomes more uniform.

Patent DE-3031477-A1 (DE)
Inventor: WUERFEL HELMUT DIPL ING DR ING
IPC: C10G1/08
Filed: 1980-08-21
Abstract: Coal hydrogenation process, such hydrogenation being carried out in the presence of a catalyst and hydrogen, in a reactor system, which is comprised of a sequence of reaction devices connected in series (11, 15); the process is characterized by the fact that at least between two of such reaction devices (11, 15) at least one partial gas and vapor stream is drawn from the intermediary hydrogenation product obtained in the reaction devices, the remaining gas stream being then introduced alone in the reactor itself; the hydrogenation reactions take then place in that reactor at an absolute pressure lower than normal, the value of such pressure being decreased by the sum of partial pressures that the draw off would provide; as a fact, these drawn-off gas and vapors do not contain hydrogen anymore and would dilute hydrogen in the reactor. The reduced flow passage of gas and vapor through the reactor system further allows to increase the filling degree, thereby providing an improved production of the reaction devices (11, 15). For a same quantity of processed coal, it is possible to reduce the size of the reaction devices (11, 15) which, again, allows a good saving in the investment and manufacturing costs.

Title: Adjuster for electrical components mounted on circuit board - has dust-excluding shaft mounting in housing wall
Inventor: HANSBAUER HERMANN
IPC: H01C10/14
Filed: 1980-11-13
Abstract: The circuit board (1) on which a number of components (2,3) are mounted, has a potentiometer (4) whose setting is to be changed by external devices. This is done by means of an internal shaft (7) which connects to the potentiometer (4). A spring (8) and a disc (9) are positioned on the shaft between circuit board (1) and housing (5) so that the disc (9) lies directly beneath the board. The adjusting body (6), is thus positioned with a pre-set tension to the inner side of the housing, its attachment (10) fitting into a cut out (11) in the housing (5). This cut-out (11) has a stepped region with two different diameters (12,13) in order to keep the adjuster (6) captive in the housing. Mounted in this way, the potentiometer (4) can be altered externally, dust being prevented from entering the housing.
Patent DE-3104209-A1 (DE)
Title: Circuit interruption relay
Inventor: HANSEN JAMES EDWARD
IPC: H02H3/10
Filed: 1981-02-06
Abstract: A circuit control device which combines the functions of a current sensor, a time-delay circuit, an undervoltage sensor and a locking device in such a manner that, once tripping has occurred, the device must be deliberately reset or restored. The current sensor has a coil which surrounds two reed switches, the reed elements of each of the switches running at right angles to those of the other switch, for reasons of vibration resistance. The coil is thus surrounded by a magnetic screen in order to screen off a portion of the leakage flux from the main relay coil. The time-delay circuit has a programmable unijunction transistor which compares a constant voltage from a voltage-divider network with the rising voltage on a capacitor. The undervoltage sensor has a second programmable unijunction transistor which compares the voltage of the DC voltage source with the constant voltage of a zener diode. In each case, the cathode of the programmable unijunction transistor is connected to the gate of an SCR (thyristor) which energises the trip coil of the locking relay when it is pulsed to "ON", which locking relay for its part opens the main relay. This also closes a further set of contacts in the locking relay, which activates a visual "tripped" display device. The device also has a reset coil in order to close the locking relay again, an override switch for energising the main relay coil irrespective of the status of the locking relay, and an energy storage capacitor for supplying power to the time-delay circuit even when the DC voltage source falls to a value which is too low to do this.
