Patent DE-19522765-A1 (DE)
Inventor: ZIMMERMANN MICHAEL
IPC: B60R21/16
Filed: 1995-06-27
Abstract: The invention concerns an airbag module which comprises a gas generator which, in response to a trigger signal, introduces gas suddenly into an airbag made of substantially airtight material. The airbag comprises an air outlet opening through which gas flows out of the bag after a given dwell time therein. According to the invention, the effective cross-section of the air outlet opening (40) is made available in a time-delayed manner when a time module has been activated. Optionally, the volume can briefly be increased in order to maintain the internal pressure in the airbag constant for a predetermined period of time.

Inventor: PACIELLO ROCCO DR
IPC: C07D213/74
Filed: 1996-01-30
Abstract: A process is proposed for producing aldehydes and alcohols by hydroformylation of olefins with more than three carbon atoms. The process involves a hydroformylation stage, in which the olefin is hydroformylated at a pressure of 50-1000 bar and a temperature of 50-180  DEG C with the aid of a rhodium catalyst dissolved in an homogeneous reaction medium, and a catalyst recovery stage, in which the rhodium catalyst is extracted. The process involves the following steps: (a) hydroformylation carried out in the presence of a rhodium complex containing a ligand in the form of a phosphorous-free multidentate organic nitrogen compound capable of forming complexes with group VIII metals, said nitrogen compound containing in addition at least one tertiary nitrogen rest which can be protonated with a weak acid; (b) extraction of the product from the hydroformylation stage, where appropriate after separation or partial separation of the aldehydes and alcohols, using an aqueous solution of a distillable acid; (c) heat treatment of the aqueous acid extract in the presence of an organic solvent or solvent mixture which is inert under the hydroformylation conditions, the aqueous acid being distilled off, in order to de-protonate the complex and convert it to the organic phase; and (d) recycling of the organic phase containing the catalyst complex into the hydroformylation stage.

Title: Energy-saving hoist operation for lift
Inventor: KAHROM KAMI DIPL ING
IPC: B66B9/00
Filed: 1996-08-08
Abstract: Two goods or personnel carrying lifts have pre-tensioned chains attached back-to-back so that when one is at a lower level the other is at a higher level. The potential energy created by a weight at the higher level is utilised in lowering the upper lift and raising the lower lift to reverse their positions. A speed regulator and generator are provided. The two lifts are connected to each other by chains to form a closed loop. A tensioning arrangement ensures that the upper and lower rest positions match. One chain also passes through a speed controlling regulator. Weight sensors are provided on each cabin which control the door of the other, so that when a weight is added to the upper lift the lower lift door closes and the upper lift descends without expenditure of power.
