Patent CA-2053837-A1 (CA)
Inventor: KISS GUNTER H
IPC: B09B3/00
Filed: 1991-10-21
Abstract: A process for rendering usable disposal products is described, in whichunsorted pollutant-containing industrial, domestic and/or special refuse undergoes a high temperature treatment.  Accompanied by the entraining of existing liquid fractions and whilst maintaining its mixed and combined structure, the disposal product is compressed batchwise to compact packs. Whilst maintaining the pressure action it is subsequently positively intro-duced into a channel heated to over 100°C and is kept in sliding, non-positive contact with the channel walls until the initially present liquids are evaporated and mechanical restoring forces of individual disposal product components are eliminated. The entrained organic constituents at least partly assume a binder function.  The shape and structurally stable, lumpy solid conglomerate forced out of the channel in this state is intro-duced into a high temperature reactor maintained at at least 1000°C and forms therein a gas-permeable bed.

Abstract: ABSTRACT OF THE DISCLOSURE       An automatic packaging apparatus having a conveyor belt and a plurality of flexible pouches forming a continuous sheet of web material. Each flexible pouch has an open end and an overlap portion specifically suitable for operation with the apparatus of this invention. The open end is separated and a load is inserted into a first active pouch of the flexible pouches. After the load is inserted into the flexible pouch, air is withdrawn form the flexible pouch. Air is withdrawn from the flexible pouch and a gas is preferably injected into the flexible pouch. The flexible pouch is then heat sealed to form a gas-tight seal. controls are used to simultaneously operate the sealing, fluid transfer and loading stations of the automatic packaging apparatus. As the flexible pouch moves from the fluid transfer station to the sealing station, the gas-tight seal is maintained.

Title: Apparatus for emptying containers
Inventor: RECK HERBERT
IPC: B65F3/04
Filed: 1992-08-28
Abstract: In order to make it possible to empty in particular, large containers with a crew of just one person, an emptying device with a tilting/lifting device 1 and a control unit 4 is described to which a trigger switch 2 is connected which is actuated by the container to be emptied as it approaches the lifting/tilting device and which triggers the raising phase of the lifting/tilting process automatically. When a preset raised level of the lifting/tilting device is reached the control unit interrupts the raising phase. In addition, a first manual actuator 8 to trigger the automatic emptying process, which actuator has an effect upon the control unit 4 only after the interruption of the lifting process, is connected to the control unit. The control unit 4 contains a programmable device 5 into which the preset raised level can be inputted. The programmable device 5 also assumes the function of monitoring the preset time spans, such as the time span between the actuation of the trigger switch 2 and the actuation of the acknowledgement signal switch 3. After the container is emptied, putting the container back down completely is accomplished by means of a second manual actuator 9.
