Title: Process and apparatus for cooling foodstuffs coated with liquid chocolate or chocolate-flavoured coating
IPC: A23G3/20
Filed: 1993-04-08
Abstract: The process and the apparatus for cooling foodstuffs or luxury foods coated with liquid chocolate or chocolate-flavoured coating takes place in a cooling duct 1 which is subdivided into two zones (10 and 11), in which the cooling air flows at different speeds. The coated foodstuffs (3) enter first of all into the zone (10) with a lower air speed, for example in the region of from 1 to 3 m/s. Surprisingly, it has been found that good cooling action, along with a likewise good quality as regards the resulting product, can also be achieved if, in the second zone, the air flows at a very much higher air speed, namely in the region of from 10 to 24 m/s. Consequently, it is possible to shorten the overall length of the cooling duct to a considerable extent. <IMAGE>

Title: Process for decreasing the toxicity of Cr(VI)-contaminated solid and liquid waste materials
Inventor: KRETSCHMER KLAUS DR RER NAT
IPC: A62D101/43
Filed: 1993-06-14
Abstract: The invention relates to a process for decreasing the hazardous nature of Cr(VI)-contaminated solid and liquid waste materials, in particular soils, building rubble and waste waters. The object underlying the present invention is to indicate a process by which the toxicity of Cr(VI)-contaminated solid or liquid waste materials can be decreased to the extent that hazard-free disposal is possible. According to the invention the contaminated material is subjected to a reductive treatment under acidic conditions; the Cr(VI) compounds are selectively and completely reduced under these conditions to Cr(III) compounds. It is advantageous to convert the Cr(III) compounds formed in the chemical treatment into water-insoluble compounds and thus to immobilise them. By means of the selection of optimum process conditions, in particular the pH and if appropriate the addition of metal cations, preferably iron, the Cr(III) compounds formed can be preserved and fixed and are highly resistant to chemical attack. All reactants used and the reaction products formed are for the most part environmentally compatible so that the chemical treatment products can be supplied for disposal in accordance with the legal stipulations.

Patent DE-4331301-A1 (DE)
Inventor: REITHER KARL
IPC: B01D47/10
Filed: 1993-09-15
Abstract: The invention relates to a differential pressure cleaning system consisting of a flow pipe (7) with a throttle (1) and at least one cleaning fluid feed device (14) fitted over the throttle (1) for treating exhaust gases from technical processes which give off gases, vapours and dusts. The throttle (1) in the flow pipe (7) takes the form of an approximately rectangular slot (2) at its narrowest point. Downstream of the slot (2) there is a displacement body (3) extending over the entire length of the slot arranged to be movable towards and away from the slot (2). This provides two roughly parallel venturi grooves (6) between the walls of the throttle (1) and the outside wall of the displacement body (3). The cross-sections of the two venturi grooves (6) can be adjusted as desired by moving said displacement body (3). The groove (1) in the flow pipe (7) preferably consists of two commercially available transverse pipes (8) of circular cross-section. The flow pipe (7) and the displacement body (3) may also be made from commercially available tubes with a circular cross-section. The differential pressure cleaner thus provided can be economically produced and combines the advantage of venturi and annular gap cleaners.

Title: IC engine inlet device - comprises mechanical charger, number of cylinders to each of which are connected inlet valve and channel and exhaust valve and channel together with variable valve timing mechanism
Inventor: HITOMI MITSUO
IPC: F01L1/344
Filed: 1993-09-24
Abstract: The variable valve timing device (15) is for altering a valve overlap time span between the inlet and exhaust valves (14) in accordance with an engine speed. An inertia charge device (2,13,21,23) is provided, whereby a negative pressure wave produced during an engine inlet stroke extends in the engine cylinder (2) air inlet channel (3) to an upstream section of it and is reflected to a volumetrically enlarged section (21,23) of the air inlet channel (3) and then becomes a positive pressure wave and returns to the engine cylinder (2). A control unit (30) causes the inertia charge device (2,13,21,23) to produce an inertia charge effect in a relatively low engine speed range when the valve timing mechanism (15) prolongs the valve overlap time span. It also causes a resonance charge device (2,13,11,12) to produce a resonance charge effect when the variable valve timing mechanism (15) shortens the valve overlap time span. USE/ADVANTAGE - Multicylinder IC engine scavenging power is improved and its output torque is increased.

IPC: F01C1/07
Filed: 1993-10-28
Abstract: A description is given of a combustion engine having at least one cylinder (1, 1A, 1B, ...) which, for the purpose of delimiting a combustion chamber, has a piston (13A, 13A1, 13A2, ...), guided in the latter, and at least one valve (7, 7A, 7B, ...) for the supply and removal of combustion gases, furthermore having a first control device (19) for operating the valve or valves as a function of the instantaneous position of a piston in the cylinder, and having a drive shaft (4) for receiving and transmitting the engine rotations. This device is distinguished in particular in that the at least one cylinder moves along a path orbiting the drive shaft and rotates the drive shaft, a second control device (9, 10, 11, 12, 12A, 12B, 13C, 13) being provided for controlling the piston movement as a function of the rotary movement of the drive shaft, and the first and second control devices being arranged in planes parallel to the plane of the orbiting path. <IMAGE>

Title: Vaned windwheel having an incident-flow pressure hub (Pitot hub) for power generation (generation of electrical energy, generation of electricity)
Inventor: KRAUSE PETER J
IPC: F03D1/00
Filed: 1993-11-16
Abstract: The vaned windwheel is a novel development in the field of wind energy technology (engineering). The hub (1), which is of relatively large design, effects a flow acceleration which contributes to a high rotational speed. Angular momentum is triggered by the vanes, which are arranged obliquely relative to the wind (2). A large energy yield results from the arrangement of the vanes (3), which is as tight as possible aerodynamically. The invention is based on my new result that the extraction of energy from the wind flow over the cube represents the optimum way of obtaining wind energy. The findings of Dr. Betz (BEZ) form the base in this case. The second-by-second area development number (FAZ) and the volume number (VZA) are to be added to his formulation of the energy content of the wind flow, referred to a square metre of area, as the result of which the designated high torques are rendered possible/explained in the case of low wind speeds on the basis of the formula BEZ x FAZ x VZA = wind energy relative to 100%. <IMAGE>
