Patent DE-3317250-A1 (DE)
Title: Wave-soldering apparatus for making soldered joints on a preferably cylindrical workpiece
Inventor: BOEHM KLAUS
IPC: B23K3/06
Filed: 1983-05-11
Abstract: A wave-soldering apparatus is proposed which serves to make soldered joints on a preferably cylindrical workpiece (13, 13a, 14, 20). The apparatus contains a nozzle (8) and a work-holding head (15) arranged in the nozzle (8). The liquid solder (1) is forced through bores (12) in the nozzle wall into the nozzle interior by means of a pump. The bores (12) are arranged in such a way that, starting from an annular channel (9) surrounding the nozzle (8), they lead into the nozzle (8) in such a way that they are directed tangentially and upwards at an angle towards the soldered joints. Due to the cyclone effect occurring as a result, the solder in the nozzle interior is given a swirling flow, which ensures short soldering times during slight heating of the workpiece and effective flowing of the solder around the soldered joints. <IMAGE>

Title: Method for producing rolls of web-shaped material and a sleeve for such rolls
Inventor: STADELMANN MAX
IPC: B65H19/28
Filed: 1983-05-13
Abstract: For the manufacture of rolls from web-shaped material such as paper rolls, the empty sleeves intended to be the cores of the rolls are provided outside the roll winding machine with a coating of a moisture-activatable hot-melt adhesive covering all or part of their surfaces. This adhesive is only activated by a liquid such as water and made sticky thereby immediately before the sleeve is introduced into the roll winding machine or even only when it has been inserted into the roll winding machine, so that during the rapid exchange of a roll which has been fully wound it can grip the front end of the rapidly incoming web of material to be wound which has been cut off from the fully wound roll and fix a new roll for the winding process. The roll winding machine is not made dirty by activation of the hot-melt adhesive by moistening, because the adhesive does not splash even at high running speeds.

Filed: 1983-07-23
Abstract: Conical crusher with sliding bearings between the outer surface of the eccentric device and the inner surface of a skirt extending downwards from the crusher head, and also roller bearings between the eccentric device and the middle shaft housing. Lubricating oil throughflow paths run through the middle shaft housing and radially outwards to an oil groove which completely surrounds the inner surface of the eccentric device and directs the lubricating oil into an oil space between the inner surface of the eccentric device and the outer face of the middle shaft housing and from the oil space into the roller bearing. A radial oil channel runs from the oil groove through the eccentric device to the surfaces of the sliding bearings and the opposing inner surface of the skirt, for the lubrication of both cooperating surfaces. The main thrust bearing has pillars with a smooth surface, which cooperates with a spherical sector having radial and self-intersecting circular lubricating oil grooves. The lubricating oil received from all the bearings flows directly through each of the bearings, without first flowing through another bearing. A counterweight is provided for the flywheel of the eccentric device. At least parts of the flywheel cylinder wall are tapered inward and upward, in order to induce a flow of lubricating oil against these walls.

Title: Process and apparatus for the drying of thermolabile materials which are liable to cake
Inventor: MOERL LOTHAR PROF DR SC TECHN
IPC: F26B3/092
Filed: 1984-01-07
Abstract: For use in the fields of materials processing, the invention has the aim of developing a process and an apparatus with which caking of, and thermal damage to, the materials during drying can be prevented, the product yield can be increased, and the heat losses can be reduced. The object is derived from this of keeping all apparatus parts which can come into contact with the material to be dried below the temperature at which a danger of caking and of thermal damage are present. This is solved according to the invention in that during the drying process the drying medium, before being heated up, is conducted around all the walls present in and around the drying space, in order to cool these. To carry out this process, an apparatus according to the invention was developed, in which all the walls in and around the drying space are surrounded by spaces through which the drying medium is conducted before it is heated up.

Patent DE-3410548-A1 (DE)
Title: Reciprocating piston combustion engine
Inventor: ZSCHERNITZ GUENTHER
IPC: F02B1/04
Filed: 1984-03-22
Abstract: Since the invention of the spark ignition engine nothing has changed in the concept of power transmission from the piston to the crankshaft. Many detailed improvements have obviously generated much energy but at the same time have also created a problem: the exhaust gas. In order to achieve a more intensive combustion and hence improved exhaust gas values, it is necessary to alter the existing ratio of piston travel to the associated crank position. The object of the present invention is to solve this problem by design measures. By retarding the piston energy is saved during compression, and energy obtained on the working stroke, whilst due to the greater lever action of the offset connecting rod much energy is obtained. The angled form of the connecting rod together with the lateral displacement of the cylinder modify the hitherto braking downwards movement of the piston in the bottom third into a smooth flow beyond BDC, accompanied by the complete combustion of the gases.

Title: Method and apparatus for clearing mud from stretches of water, ponds and the like
Inventor: KREYENBERG HEINER DIPL ING
IPC: E02F3/90
Filed: 1984-03-31
Abstract: Excavators which have tracked running gear and a pivotable superstructure are used to remove mud from ponds and relatively small lakes. A boom with a grab bucket is fastened to the superstructure. However, the boom only has a limited radius of action. For the purpose of simplifying the mud removal, provision is made for homogenizing of sediments with overlying water and/or other added diluting water, in particular fed-back concentrated water coming out from the sludge, before and/or during the mud removal. In terms of the apparatus, such homogenizing is carried out with an excavator whose boom consists of two support arms which are essentially of the same length and are connected to one another in an articulated manner, in which arrangement the outer of the two support arms can be actuated via a rope guide and carries a sinkable mud pump at its free end. A homogenizer is arranged ahead of the mud pump.
