Title: Supermarket trolley with self service costing of goods - has cost and weight totalled by customer with checkout based upon weight agreement
Inventor: FRANKEN STEFAN
IPC: G07G1/00
Filed: 1990-11-07
Abstract: The supermarket trolley (2) has a basket for goods on a frame that also provides a mounting for a small computer and display module (4).

Title: Washing textiles in automatic washing machine - by using twin drum principle and recycling container to store solns.
Inventor: STOLL MANFRED
IPC: D06F23/02
Filed: 1991-02-14
Abstract: Process is effected in a fully automatic washing machine using the twin drum principle, and for storing the solns. The process starts with the flooding through of the washing with rinsing soln. from the recycling container without adding cleaning agents and with a high surplus of free soln. Before thesoln. is supplied into the drum, a small proportion of rinsing soln. is pumped into the sewage system out of the recycling container. After the flooding of the washing, the free soln. and the soln. that becomes free through spinning are pumped back into the recycling container. Specific spinning speeds are stipulated for different materials. After the spinning process, the drum revolution speed is reduced and a fresh water detergent mixt. is fed into the core for a short while. The washing process is interrupted at intervals by spinning. ADVANTAGE- The process and associated washing machine cut water, energy and detergent consumption while requiring little expenditure in technology.

Title: Glass pane bonding - has shaper for each pane for accurate alignment before they are pressed together with distance pieces and bonded
Inventor: GRENZEBACH RUDOLF
IPC: E06B3/673
Filed: 1991-03-05
Abstract: To produce two curved glass panes, bonded together in parallel, with a distance piece between them, each pane is laid horizontally in a shaper with a contact surface in the required shape for the outer side of the glass, with accurate alignment and then bonded to it. The shaper for the lower pane is shfited to bring the edges into the required position and alignment, and then secured against further movement. After the distance pieces have been placed on the aligned pane, the upper pane is brought over the lower pane, and its shaper is shifted to align its edges to the lower pane, and then fixed against further movement. The shapers, with their panes, are pressed together and bonded. After bonding, the pane package is removed from the shapers. Pref. the panes are held to the contact surfaces of the shapers by suction. An adhesive etc., is inserted between the panes, without altering their position relative to each other. USE/ADVANTAGE - The bonded panes, of glass or plastics or other similar materials, are for use as vehicle windows. The method takes material inconsitencies into account within the permitted tolerances, such as glass thickness or deg. of curvature, to give accurately bonded panes for immediate use without material loss

Patent DE-4136468-A1 (DE)
Inventor: RISTIC STEVAN
IPC: A01D41/14
Filed: 1991-11-06
Abstract: The present invention describes a self-propelled combine harvester with a horizontally foldable cutting unit consisting of two cutting-unit halves (14, 15) so that the cutting unit, after being used for work, can be pivoted from the working position into a transport position, so that the permissible maximum width for road transport is not exceeded. To make it possible by simple means to obtain the pivoting movement of the two cutting-unit halves (14, 15), there are provided two very simply constructed drives, of which the first performs the introductory pivoting movement from the working position into the transport position and the second drive is switched on only when the two cutting-unit halves (14, 15) are at a point just before they reach their end position for road transport. The two drives can be designed as follow-up drives. It is also possible, however, to switch on the second drive in addition to the first, that is to say both drives remain switched on to the end. <IMAGE>
