Patent DE-4328202-A1 (DE)
Title: Circulating cupboard
Inventor: ZINK RALF
IPC: A47B51/00
Filed: 1993-08-21
Abstract: In order to make it possible for disabled people to access the upper shelf fittings of a cupboard, the shelf fittings are mounted so as to be displaceable in height. This is achieved by a paternoster-like mechanism, which has proved to be expensive owing to its construction with a plurality of chains and guiding elements, and requires a lot of space. The novel mechanism is relatively simple and requires little space. The shelf fittings (1) are not interconnected e.g. by a chain, but lie one on top of the other, guided by a guiding frame (6). A guiding disc (3) fixed on the rear side of the cupboard moves the compartments individually from one compartment column to the other. This is effected by a pin (2) which is fitted on the rear side of the compartments and engages in the slot of the guiding disc (3). At the same time, a compartment is conveyed back in the upper part of the cupboard. This mechanism finds application in all storage systems in which the entire room height is to be utilised, or the maximum access height of the user is limited, e.g. by a disability. <IMAGE>
Patent DE-4337710-A1 (DE)
Title: Increasing the crushing force of slowly rotating multiroll crushers in the case of inhomogeneous material to be crushed
Inventor: HOELTER HEINZ PROF DR
IPC: B02C4/42
Filed: 1993-11-05
Abstract: A hydraulic drive for slowly rotating two- or three-roll crushers is fitted with a variable servopump. In order to design the hydraulic drive in an optimum fashion, the crushing operation is performed at a pressure which is reduced by the factor of the increase in crushing force required for extreme crushed parts. In the case of the occurrence of these extreme parts, the hydraulic pressure is increased in conjunction with a decrease in the volumetric flow. The required adjusting time is achieved by means of a torque arm which makes the drive capable of being swivelled out and which is supported via a retractable spring element which preferably acts at both ends.
