Patent DE-3931673-A1 (DE)
Inventor: MOLL PHILIPP
IPC: D05B33/02
Filed: 1989-09-22
Abstract: The workpiece layers to be processed are suspended in a vertical plane and fed automatically to a scanning and alignment station (R). To this end, the workpiece layers are gripped in a horizontal starting position, moved into the vertical position and conveyed to the scanning and alignment station (R). After alignment, they are taken immediately and transported to the processing station (N). The device for carrying out this process has two conveying devices (F, F'), each consisting of a feed conveyor (Z; Z') in the form of a manipulator and a transport device (T; T') formed by a conveyor belt (48; 48'). The workpiece layers are held in the scanning and alignment station (R) by mechanically movable clamps (20; 20'). The transport devices (T; T') can be moved to an d fro between a driving and a non-driving position in the region of the clamps (20; 20'). This enables the feed conveyors (Z, Z') to transfer the workpiece layers to the clamps (20; 20'), which can then be moved freely in order to align the workpiece layers with each other.

Title: IC engine exhaust purification - involves use of shock waves in exhaust to raise temp.
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/34
Filed: 1990-01-12
Abstract: The metod is used for reducing the amount of environmentally harmful products in the exhaust gases of an IC engine.  The exhaust ducts (321(1) to 323(4)) are connected to a common manifold (K1) which increases progressively in cross-sectional area as each exhaust duct is connected to it. The exhaust gases generate shock waves in the manifold (K) and cause a rise in temp.  Additional air is supplied through the air duct (6) in the last exhaust duct (323(4)) in order to utilise this rise in temp. to burn away any harmful products.  Air is drawn through the ducts (5,6) by the ejector effect of the exhaust gases in the last duct (323(4). USE - IC engine with exhaust gas purification.

Title: Fuel injection pump for IC engine - has grooved piston for return flow at max. pressure
Inventor: ROSSIGNOL FRANCOIS
IPC: F02M59/36
Filed: 1990-03-31
Abstract: The fuel injection system has a solenoid valve (5) in the low pressure feed to control the start and end of the injection cycle. A sloping bore (3) crosses the piston bore of the pump and the far end forms a return feed from the pressure chamber (10). The piston has a groove (8) which bridges the two parts of the sloping duct and forms a simple return path at max. pump pressure. The return path allows any gas bubbles to escape, as well as excess high pressure fuel. It prevents cavitation at the injector and reduces wear.

Title: Machine for cutting off paper rolls -  has sensors to detect state of parent roll and travelling clamp to allow ends to be discarded
Inventor: ARNDT WALTER
IPC: B26D7/18
Filed: 1990-10-16
Abstract: The paper rolls, which may be kitchen rolls, toilet rolls etc., are cut off from long parent rolls stacked in a magazine (1) ready to be handled through a machine with a cut-off disc (14). The cut rolls must have square ends and be of correct length, whilst starting (20) and end pieces must be separated out. These requirements are achieved in a machine having three fixed clamps (8) and a clamp (10) which can be traversed from a position near the cut-off disk to a position some distance away (as shown). Pushers (4) on a continuous belt push the parent roll into position and through the cutting cycle. After the first cut the starting piece drops out of the way. The travelling clamp is then moved up close to the cut-off disk and acts as a rest for the cut-off rolls until the last full length roll can be cut. This condition is registered as a gap by sensor (9). ADVANTAGE - Exclusion of starting and end pieces is guaranteed. Rolls are cut to exact length with square ends. Adjustment can be made to ensure accurate registration of patterned products.

Patent DE-4040190-A1 (DE)
Inventor: STRIPF HELMUT
IPC: G01N29/07
Filed: 1990-12-15
Abstract: According to a process for measuring the propagation time of ultra-sound during the pulse reflection method, at least one exciting pulse, if possible shaped as a shock wave, is emitted by a probe and covers a leading distance up to an object to be examined having a front and a rear wall, whereas at least one reflection pulse is generated at said front and rear walls. In order to improve a process of this type in such a way that propagation times may be reliably measured, in order to detect the thickness or abnormalities of an object, even in the case of rough surfaces, lacking and adulterated pulse reflections, a time window for receiving the reflection pulses that follow the exciting pulse is determined, within which all successive reflection pulses are digitalized, then the reflection pulses located within the time window are digitally filtered and parameterized, the filtered and parameterized reflection pulses are transmitted to a calculating unit and evaluated by means of a predetermined algorithm on the basis of variable criteria.

Title: Treatment plant for removing foreign matter from coal - has three settling tanks which are subjected to air pulses
Inventor: WEIFFEN KARL-HEINZ
IPC: B03B5/24
Filed: 1991-01-30
Abstract: A treatment plant for separating foreign matter from coal, consists of three settling tanks (11,12,13) installed side by side. A mixture of coal, foreign matter, and water, flows into the first settling tank (11). Whilst in the tank the mixture is subjected to pulses of air generated by fans (20) which deliver the air to the expansion chamber (17). The air pulses generate pulses in thhe water and so separate the heavier foreign matter from the coal. This process is repeated in the second and third settling tanks (12,13), with foreign matter being removed in each tank. USE/ADVANTAGE - Removal of foreign matter from coal. The use of three settling tanks improves the degree of removal of foreign matter.
