Patent DE-3142469-A1 (DE)
Title: Cooking vessel
Inventor: SCHAWALDER ALBERT C
IPC: A47J36/06
Filed: 1981-10-27
Abstract: By novel shaping, a cooking vessel is intended to facilitate work at the cooker in that, for letting off steam, the lid is only to be tilted and it is no longer necessary to lift the lid off or to push it to the side, from where it can easily drop off. This is achieved in that the cooking vessel has below its upper edge a circumferential, outwardly curved zone forming part of a spherical surface. In the normal position of use, the lid rests with its edge in the central region of the said annular zone and, when the lid is tilted, its edge slides along its annular zone and opens a gap at the edge of the lid. As a result, it is possible to allow the steam to escape in a targeted manner towards the side away from the cook or in the direction towards a vapour extraction device which may be present.

Title: Device for aerating and/or ventilating rooms
Inventor: HAMMER JOSEF
IPC: E04B9/02
Filed: 1981-11-17
Abstract: A device (1) for aerating and/or ventilating rooms (2) with humid and/or greasy atmosphere and for separating grease and humidity from the air is composed of individual cassettes (4) e.g. to form a lower ceiling, it also being possible, however, for the device e.g. as a single cassette to form a grease-collecting grill. In this connection, there are provided parallel links (5 and 6) which are in cross-section in each case open on one side and in particular circular arc shaped or groove shaped and which overlap alternately in each case with their open sides and expose between the link edges (5a and 6a) a passage for the air. The cross-section in the case of at least one sort of links with a cross-section in each case open to the same side extends at the same time over more than a semi-circle, and this possibly applies for both link sorts; between the contractions of the edges (5a, 6a), which engage behind one another, of the individual links, there is thus created in each case a chamber (7) which expands and then again narrows the flow cross-section and which extends in the longitudinal direction of the links (5 and 6) parallel thereto. The links and the chambers (7) are closed off on the end-side transversely to their longitudinal extent, there being provided on at least one end wall (8) at the lowest point of the upwardly opening links (5) a passage (10) for separated impurities. <IMAGE>

Title: Propellant-charge igniter for propellant charges of extremely high charging density
Inventor: BIELE JOACHIM K DIPL PHYS DR
IPC: F42C19/08
Filed: 1982-05-13
Abstract: In order to prevent excessively high pressure rises during the ignition of propellant charges of extremely high charging density, the igniter is built into the propellant charge in such a way that, immediately after ignition, the extremely high charging density is converted into a lower charging density. This is achieved in that the ignition process is initiated directly at the projectile rear. It is thus possible that the propellant gas first forming will immediately cause the acceleration of the projectile, and that, after the end of combustion, an expansion space larger than the geometrically limited charge space will consequently be available.
Patent DE-3220842-A1 (DE)
Title: Process and apparatus for filling the inner boiler of a combustion calorimeter
Inventor: LIEBELT CHRISTIAN DR ING DR
IPC: G01N25/26
Filed: 1982-06-03
Abstract: An inner boiler of a combustion calorimeter can be filled precisely and with high accuracy when the inner boiler is first coarsely pre-filled with a first filling quantity which is less than the required filling, and that the quantity of water which is still lacking is determined by weighing the pre-filling and is fed in, finely metered, in particular iteratively, in several steps. A balance can be provided on which the inner boiler is placed during filling. A coarse filling device is thus combined with a metering, fine filling device, so that first the coarse filling device and then the fine filling device can be actuated, regulated by means of the balance. The fine filling device suitably delivers less water, on its first actuation, than corresponds to the quantity of water still lacking, so that the quantity of water still lacking is thereafter again determined and a quantity of water not quite corresponding to this can be added, and so on.
