Title: Structural element in the form of a panel, in particular for roof structures and systems of binders and joists
Inventor: BEER IGNAZ DIPL ING
IPC: E04B7/22
Filed: 1981-08-27
Abstract: A structural element in the form of a panel, in particular for roof structures and systems of binders and joists, comprises wood wool or the like which is bound by cement or a different binder and has reinforcing inserts consisting of natural wood. These comprise pieces of timber which are stripped of bark and are otherwise unmachined, and they are arranged in each case with their thicker end in the opposite direction. In order to improve a panel of this type such that the bending strength of the pieces of timber alone is sufficient to withstand the maximum permissible bending loading of the panel, and that the panel, at the same time, takes over heat insulation and sound absorption, the pieces of timber (2, 3) consist of slowly grown, branch-free and clear-felled fir or spruce wood. <IMAGE>

Title: Process for enzymatic elimination of oxygen
Inventor: KOHLBECKER GUENTHER
IPC: A23L5/20
Filed: 1982-02-06
Abstract: By means of a novel process for enzymatic elimination of oxygen, the colour changes and flavour changes occurring in foods and confectionery are prevented and the storage life is extended. Oxygen is reacted in the presence of oxalate using oxalate oxidase to give carbon dioxide and hydrogen peroxide:  O2 + oxalate @ 2 CO2 + H2O2 A possible subsequent reaction by catalase gives the following overall reaction:  1/2  O2 + oxalate @ 2 CO2 + H2O Oxalate oxidase can be added with or without oxalate direct to beverages such as fruit juices, beers, wines etc. but also, inter alia, to mayonnaises, toothpastes and chewing gums. The majority of systems show a pH favourable for the activity of oxalate oxidase of between 2.5 and 6.5. Oxalate oxidase is thermally stable up to more than 80 DEG C. By this means, protection against oxidative influence is possible even during pasteurisation. Many beverages contain the required substrate oxalate, so that after addition of oxalate oxidase, not only an elimination of the oxygen but also of the often undesirable oxalate is achieved. The process is also suitable for sugar-free media.

Patent DE-3209608-A1 (DE)
Title: Drive for doors and the like
Inventor: WEISS BRUNO E DIPL ING
IPC: E05F15/63
Filed: 1982-03-17
Abstract: A drive (1) (Fig. 2) serves for the opening and closing of wing doors in particular. It has an electric motor (4), a gear (5) and a closing spring (6). The motor (4) is driven only in one direction of rotation for the opening of the door. During the opening operation, the closing spring (6) is simultaneously tensioned. The gear between the motor (4) and the output shaft (7) is made free of self-locking, so that, during the closing operation by means of the closing spring (6), the motor (4) can be co-rotated idly and at the same time serves as a damping element. The activation of the motor takes place essentially via time switches, whilst during the opening operation, for example from an opening angle of 80 DEG , an electrical braking and a reduction in the motor power take place. In the open position of the door, the reduced motor torque is available for keeping the door open against a built-in stop (27). After the motor has been cut off at the end of the total opening time, the door is moved in the closing direction by the closing spring (6). Near the closed position, the motor (4) is cut in once more for a limited time counter to this closing direction, so that a damping of the closing movement occurs. The motor (4) is designed as a blockable motor, so that on the one hand the blocking in the open position and also the contrary running during damping in the course of the closing operation can take place without damage. The motor activation provided and also the overall design of the drive (1) ensure that a smooth opening and closing movement of the door is obtained, at the same time at a low total outlay. <IMAGE>
