Patent DE-4212016-A1 (DE)
Title: Full colour image prodn.
Inventor: BUJESE DAVID P
IPC: G03G15/01
Filed: 1992-04-09
Abstract: Liq. toner colour image is formed on a photosensitive surface (65) using developing means (84) to develop a latent electrostatic image formed on the surface by imagewise exposing and charging means (68,69). The developed liq. image is transferred to a first intermediate transfer surface (72) to be dried by drying means (81) before being transferred to a second intermediate transfer surface (23) contactable with the first and having an adhesive or tacky quality effective to remove the dry image. A final receiving surface (12) is fed to the second intermediate transfer surface and the dry image is fused onto it by fusing means (50).     The photosensitive surface and the first intermediate transfer surface are pref. conductive. The first intermediate transfer surface is smooth, metallic, and non-oxidisable. It is esp. aluminium, stainless steel, or chrome plated steel. There is a gap between the photosensitive surface and the first intermediate transfer surface which is filled with a liq. during transfer which is a non-polar insulating solvent. The liq. image on the intermediate transfer surface is dried using an air dryer. The second intermediate transfer surface is dielectric, esp. silicone rubber or fluorosilicone. The final receiving surface is fed over the second intermediate transfer surface by a series of feed rollers. The fusing means comprises a rotatable fusing roller coated with silicone or PTFE which is heated to provide both heat and pressure during fusing.

Patent DE-4329138-A1 (DE)
Title: Vacuum pot (insulating pot)
Inventor: SCHAMBERG STEFAN
IPC: A47J41/02
Filed: 1993-08-30
Abstract: The invention is based on a vacuum pot (1) for keeping brewed beverages warm and comprises an open-topped receptacle which can be closed by a lid but is otherwise of double-walled construction throughout, including its bottom region having an inner (7) and outer (8) wall. The gap (13) formed thereby is largely evacuated and sealed gastightly. When the brewed beverage is being made, the bottom region of the vacuum pot (1) rests on the warming plate (15) of a beverage-brewing machine, the warming plate (15) continuing to be heated even after completion of the brewed beverage. According to the invention, the inner (7) and outer (8) wall touch in the bottom region of the vacuum pot (1) in such a way that in each case a heat-conducting bridge (12) results there, via which heat is able to flow from the warming plate (15) into the beverage in the vacuum pot (1). An advantage of the vacuum pot (1) according to the invention is that, despite its insulation against thermal conduction, heat can be transported from the warming plate (15) onto the inner wall (7) for the purpose of preheating the inner wall (7) and maintaining the temperature of the brewed beverage. <IMAGE>

Title: Process and installation for recycling plastics and electronics waste
Inventor: ROSIN HARRY PROF DR MED
IPC: B03B9/06
Filed: 1993-09-02
Abstract: For recycling or recovering useful materials from mixed plastics/electronics waste, use is made of a process and a recovery installation by means of which the starting material is initially brought to -120 to -150 DEG C, without generating environmentally polluting emissions, and is thereby made more brittle in order for it to be comminuted and sorted. Both the comminution and the sorting take place in the low-temperature state, with the result that it is possible to recover both the useful metals and the plastics thermally unchanged, so that they can advantageously be further processed. Consequently, public acceptance with respect to the plastics and computer industries is increased, since recyclability and consequently the avoidance of waste can be ensured. <IMAGE>

The data source is an image processor and the test data are test pictures. ADVANTAGE - Quick, automatic fault detection.
Patent DE-4335385-A1 (DE)
Title: Conveying apparatus for producing a single layer of tobacco
Inventor: NIEHUES HEIKO
IPC: A24B3/18
Filed: 1993-10-16
Abstract: The invention relates, within a conveying apparatus for producing a single layer of tobacco, to the point of transition between an oscillating conveyor and a band conveyor running at higher speed. The object is to form a closed tobacco web on the band conveyor. This is achieved by means of a throw-off edge limitation (23) of the oscillating conveyor (6), which is such that the tobacco thrown off during each oscillating action is distributed on the band conveyor (8) within a throw-off area profile (24) which continues without a gap in the conveying direction during virtually each oscillating action. As an example, the throw-off zone of the oscillating conveyor can be provided with rectangular tines, via the front and rear throw-off edge portions (27) and longitudinal edges (26) of which the tobacco passes, multiply distributed, onto the band conveyor (8). A single layer of tobacco formed evenly in all directions can be produced in this way. <IMAGE>

Title: Multilayer, bulky filter material
Inventor: PLOCH SIEGFRIED DR
IPC: B01D46/30
Filed: 1993-10-27
Abstract: The invention relates to a multilayer, bulky filter material, preferably a filter nonwoven web, in which, between two knitted layers, vertical or virtually vertical pile pleats are arranged, both the stitches of the knitted layers and also the pile pleats being formed from one and the same fibres. The novel filter material for gas filtration and liquid filtration enables the pore size of the individual layers, which is jointly critical for the filter effect, to be shaped differently between the inflow and outflow side and thus to create the filter efficacy of thin filter materials with a defined surface filtration. <IMAGE>
