Title: Pulsed MIG/MAG welding machine control - automatically switches to optimal non-pulsed or pulsed welding mode
Inventor: HORNUNG KURT
IPC: B23K9/095
Filed: 1992-08-27
Abstract: In a control process for a pulsed MIG/MAG welding machine, which can operate with presettable operating parameters (e.g. work material, gas, wire diameter, etc. selectively in a first non-pulsed mode with continuously adjustable welding energy and in a second mode with controlled and pulsed energy supply, the novelty is that (a) mode information (4), for several operating parameter combinations (3), is stored in a data store (2) of the machine controller (1) for giving precedence to the first or second mode as optimal mode for the existing operating parameter combination; and (b) automatic mode switching is effected in accordance with the mode information (4) fed from the data store (2) into the machine controller (1). When the machine has a mode switch for mode selection, optimal or non-optimal setting of the mode switch is indicated by a signal, e.g. a lamp. When the machine has its operating parameter combinations prioritised by the welder, the mode information is freely programmable. ADVANTAGE - The welding operation is automatically set to the optimal welding mode.

Patent DE-4237630-A1 (DE)
Inventor: WOLFF HANS-KLAUS DIPL ING
IPC: F16L55/033
Filed: 1992-11-05
Abstract: A compressed-air venting apparatus essentially comprises a housing (1, 2, 19, 17, 5) having an inlet (18) and an outlet (4) and sound-damping means (3) arranged in the housing (1, 2, 19, 17, 5) between the inlet (18) and the outlet (4). In order to prevent an excessive dynamic pressure forming in the housing interior when, after a relatively long operation period, the compressed-air permeability of the sound-damping means lessens, the invention provides channels which pass through the sound-damping means (3) in the longitudinal direction and through which compressed air can flow from the inlet directly to the outlet. In a compressed-air venting apparatus of this type, the sound damping, as a result of the channels which are designated as emergency passageways, is not as good as in compressed-air venting apparatuses which do not have such emergency passageways. In order to avoid this disadvantage, the compressed-air venting apparatus according to the invention exhibits a principal air path, leading from the inlet (18) to the outlet (4) via the noise-damping means (3), and an auxiliary air path (10, 9, 8, 4) which is provided parallel to said principal air path and is composed of a first sub-channel (10, 9, 8) which extends from the inlet (18) and of a second sub-channel (4) which is formed by the outlet (4) or extends to the outlet (4), the two sub-channels (10, 9, 8, 4) not being filled by the noise-damping means (3). The two sub-channels (10, 9, 8, 4) are connected to each other via the noise-damping means (3). The two sub-channels (10, 9, 8, 4) and that part of the noise-damping means (3) which connects the two sub-channels (10, 9, 8, 4) are arranged such that said part of the noise-damping means (3), when being acted upon by a dynamic pressure, releases a direct connection between the two sub-channels (10, 9, 8, 4). In this compressed-air venting apparatus, there is no direct connection in normal operation (noise-damping means are not contaminated) between the inlet (18) and the outlet (4), which leads to the atmosphere, as a result of which good noise damping is achieved. <IMAGE>

Title: Packing storage and transport unit for chemicals - uses separate conforming transport containers and inner plastics goods containers for easier return and recycling.
Inventor: HARTMANN HELMUT DR
IPC: B65D77/04
Filed: 1992-11-12
Abstract: The transport packaging and goods packaging is strictly separated at the manufacturers. The transport packaging are standard disposable or reusable containers made independently of their goods contents and relevant packaging. These transport containers are preferably offered on deposit to ensure reuse. The goods packaging are mainly plastics containers matching the standard sized inner form of the national and international standard transport containers. The two containers touch one another but are not in keyed engagement. These plastics goods containers can be disposed of by recycling systems. The transport containers can be stacked up with smaller containers inside the larger containers for easier return. USE/ADVANTAGE - Especially suitable for the paints industry. Economic re-use of the transport containers is encouraged. Legally required recycling of the goods packaging is made easier.

Title: Housing equipped with a radial bearing
Inventor: HACKEWITZ FRIEDRICH-W VON DR I
IPC: F16C17/24
Filed: 1993-03-18
Abstract: A housing (1) equipped with a radial bearing and composed of an elastic material bears a radial load (F) acting upwards in a vertical centre plane (11) and has a through hole (7) in which contact loads (10) are supported in a flexible manner in a load zone (8, 9) of the radial bearing. To provide the radial bearing with a long service life despite its relatively thin housing wall (14), at least one strip (19) manufactured from a material with a coefficient of thermal expansion correspondingly different from the material in the housing (1) is firmly connected to an upper peripheral section (17) of the housing wall (14) by bonding, welding or clamping with frictional engagement. When the upper peripheral section (17) of the housing wall (14) heats up to operating temperature, the bore (7) of the housing (1) undergoes a small thermally induced change in its circumferential curvature due to a difference in the thermal expansion of the strip(s) (19) in the region of the load zone (8, 9) of the radial bearing and this change in curvature opposes an elastic change in the circumferential curvature of the bore (7) brought about in this region by the contact loads (10). <IMAGE>

Title: Fixed bed bioreactor having a varying bed state parameter
Inventor: STELZER HANS DIETER DIPL ING
IPC: C12M1/40
Filed: 1993-05-21
Abstract: There is a fixed bed bioreactor in which a specific change in the bed state parameter is provided in the direction of flow and to which is assigned a support material packing density. It is desired here to improve the mass transfer to be carried out by the fixed bed independently of the cross-section of the fixed bed. This is achieved by the bed state parameter changing in the direction of flow being the packing density. That is the mass transfer between flowing fluid and fixed bed may be improved by dispersions in the fixed bed in the direction of flow being prevented by specific change of the packing density and/or of the interstitial space volume and/or of the external porosity of the support material. <IMAGE>
