Title: Machine for filling and sealing bags
Inventor: SCHIRBEL MANFRED
IPC: B65B43/46
Filed: 1984-05-04
Abstract: To hold open bags during transport from a filling station to a sealing station, suction strips (110a, 110b) are used. The latter are moved inwards together with clamping plates (109a, 109b) once the bags have been filled and lowered, the suction strips (110a, 110b) coming to rest against the side walls of the bag. Then the suction strips (110a, 110b) are moved upwards, and in this process they slide along the side walls of the bag. The bag is taken to the sealing station with side walls held in this manner. The suction strips (109a, 109b) are only detached from the bag when the bag tab is held by folding knives.

Title: Solar-heated cooker with heat accumulator
Inventor: MUELLER WALTER
IPC: F24S20/30
Filed: 1985-02-15
Abstract: Arranged on the upper part of a boiler-shaped accumulator are a number of solidly connected plate supports which conduct heat well and on which cooking plates with heat control are mounted. Plate support and cooking plate have in each case three matching inclined surfaces which are arranged concentrically. By turning the cooking plate, the contact surface can be decreased or increased during cooking, as a result of which any adapted heat control is made possible. The cooking plates are provided with a removable insulating covering. The accumulator can be filled with water or thermal oil. The cooker is installed in a cooking room higher than the solar collectors so that the forward and return run pipe run upwards at an angle to the cooker. As a result, the heat transfer medium heated in the absorber pipe can circulate of itself and heat the accumulator up to 200 DEG C. At any time of day, any foods can be prepared simultaneously on all plates. This cooker can be used particularly suitably in desert regions with a lot of sun and little wood for burning.

Title: Castor arrangement on a mobile lifting and setting-down device for transportable large containers, e.g. containers, cabins or the like
Inventor: RIEDL REINHOLD DIPL ING
IPC: B60B37/10
Filed: 1986-01-14
Abstract: A mobile lifting and setting-down device for large containers has rack and pinion jacks to be attached at the container corners, whose racks 11 are provided on supports 10 for the relevant large container. Castors 13 are arranged at the lower ends of the supports 10. In order also to be able to move very heavy large containers with such lifting and setting-down devices, a wheel axle 12 is coupled to each support 10, on which wheel axle two castors 13 are arranged on each side of the coupling device 12. The castors 13 are mounted so as to be axially movable on the wheel axle 12 in order to allow the castors 13 to move apart in the case of extreme loading of their tyres 15 and the ensuing flattening thereof in the contact region with the ground. This movement-apart of the castors 13 is limited on each side of the coupling device 14 by two stops 26, 27. The outer stops 27 are arranged releasably so that, when the use of the lifting and setting-down device has been completed, the castors 13 can be removed from the wheel axles 12 and stowed in a simple space-saving manner. The latter also applies to the wheel axles 12 which can be removed from the supports 10. <IMAGE>

Filed: 1986-05-05
Abstract: A resistor (RM), which is dependent on a magnetic field, is physically arranged in the air gap (G) of the storage inductor (L) and electrically in a control device (RM, R4, K3, UREF) of a switched-mode power supply for automatic limiting of the inductance current (IL) of the switched-mode power supply, especially of a forward converter or push-pull converter, in the event of an overload or short-circuit. The value of the resistance of the resistor (RM) which is dependent on a magnetic field grows as the inductance current (IL) increases and switches off the current-switching semiconductor switch or switches (S; S1, S2) on reaching a limit value which can be predetermined. <IMAGE>
Patent DE-3619301-A1 (DE)
Inventor: KAESLER HERIBERT DIPL ING
IPC: G01N21/3504
Filed: 1986-06-07
Abstract: A first exhaust gas sample is collected from the exhaust gas stream (A) by means of a heated sampling section (2, 3, 5) and is subjected to an IR measurement without dilution. Aldehyde is washed out of a second sample of the exhaust gas in a scrubber (8) and then a second IR measurement is performed in the same IR measuring instrument (6, 7) to determine the effect of the hydrocarbon. A difference signal is derived from the two measurements and is used as measured quantity for determining the aldehyde concentration in the exhaust gas. The two measurements can be performed consecutively by the switching of a three-way valve (4) in a quasi-continuous method; alternatively, the aldehyde-containing exhaust gas can be measured in a first cell and the aldehyde-free exhaust gas in a second cell, both cells being placed in the beam path of an IR radiator. A cross sensitivity of the IR measurement to water molecules can be corrected for either by calculation or by a dew point measurement in the exhaust gas. <IMAGE>
