Patent DE-4103500-A1 (DE)
IPC: E04H5/02
Filed: 1991-02-06
Abstract: A warehouse (1), which can be expanded to correspond to the respective circumstances, for combustible products stored in drums (19, 20) is composed of few components in the manner of a construction kit. Each unit (7, 8, 9, 10) of this type consists of a collection trough (5, 13), serving at the same time as foundation, and of a plurality of attachment elements (4, 21, 22) which are fitted onto the surrounding walls (2, 3) of the collection trough (5, 13) and are of U-shaped construction. These U-shaped attachment elements (4, 21, 22) are equipped with a grid (6, 23) on which the drums (19, 20) can be stored placed thereon. Such units (7, 8, 9, 10) are then arranged spaced apart facing one another with the open sides and connected via a travel path plate (11) so that they can then also be loaded and serviced easily. Any leaking harmful substances are collected in the collection troughs (5, 13) and then pumped off from the respective collection trough in question or also from a plurality of collection troughs in the case of a corresponding overflow. In addition to the advantageous possibility of the expansion of such a warehouse (1) by simple attachment of corresponding units, the warehouse (1) affords the great advantage that reliable sealing-off from the environment is possible. Moreover, the stability of the individual unit and of the overall warehouse should be emphasised. <IMAGE>

Inventor: KNOST DIETER DIPL ING
IPC: A21C9/08
Filed: 1991-12-24
Abstract: The invention is intended to ensure protective dough treatment during dough processing by means of a dough divider and a subsequent machine (for example an intermediate proof cabinet) in any situation, even when the type of dough or the size of the piece of dough is changed. 
<??>This is achieved using the invention in that the drive motor (19) of the dough divider (1) is driven at different speeds by a frequency converter (4) is accelerated over an acceleration time (starting ramp) and is stopped over a braking time (braking ramp). In order to coordinate the dough divider with the subsequent machine, the drive motor (19) receives the starting pulse as a function of a position at which the piece of dough is handed over from the subsequent machine.

Title: Plank-loading system into continuous gluing machine - delivers sideways and deflects downwards from flat position for subsequent positioning edgewise or lying flat
Inventor: FROEHLICH ADOLF DIPL ING
IPC: B23Q7/16
Filed: 1992-06-29
Abstract: The system loads a continuous seam-gluing machine, the planks being mounted edgewise or lying flat as desired. The planks (5) are delivered lying flat above the path in which the press-slide (4) works, and are then transported sideways. The planks are deflected obliquely downwards from the horizontal conveyor surface to the inlet end of the machine table (2). Here they are either tilted by the press-slide into the edgewise position, or turned so as to lie flat as they are thrust into the machine. This can be done by a force applied to the plank leading edge, e.g. by a conveyor. USE/ADVANTAGE - Simple, low cost, and rapid loading of planks into continuous gluing machine.

IPC: F02M59/44
Filed: 1993-01-21
Abstract: A pre-assembled delivery valve and holder assembly for installation in a delivery passage from a pump working chamber to a fuel-injection line of an internal combustion engine. The assembly comprises a delivery valve member (19) openable towards the fuel-injection line against a return spring (37), the member being guided in a delivery valve holder (7) and being arranged to cooperate with a valve seat (25) of a body (27) screwed into the valve holder (7).
