Patent DE-3335875-A1 (DE)
Title: Method and device for monitoring the thread tension of an elastic thread
Inventor: FLAEMIG PETER
IPC: D02H13/22
Filed: 1983-10-03
Abstract: In a method for monitoring the thread tension of at least one elastic thread which is wound on a carrier with a set thread tension for further processing, the set thread tension is determined before and during the winding operation with the aid of a light barrier (9, 10) by measuring the diameter of the elastic thread (4) using the attenuation of the beam. The diameter depends on the thread tension and the measurement obtained is compared in each case with a specified diameter value allotted to said thread tension. The result of the comparison is evaluated in an evaluation circuit (25 to 43) which contains a microcomputer (28) and a gated peak-value detector circuit (40) in which the individual infrared laser reception signals are rectified and are converted into direct-voltage stepped signals, in particular in phase with the laser signals. <IMAGE>

Title: Process and device for detecting metallic foreign bodies in the crop flow of a harvester
Inventor: HILL AMOS G
IPC: G01V3/11
Filed: 1983-11-12
Abstract: When a metallic foreign body (39) is detected in a crop flow (38) conveyed to a cutting box (18) of a harvester (10), the crop feed is immediately interrupted before the foreign body (39) reaches the cutting box (18). Moreover, an alarm is triggered. When the operator reverses the conveying device for the crop (38) and restarts it in order to eject the crop (38) from the harvester (10) and bring it away from the cutting box (18), the rearwardly directed crop flow (38) is examined once more by the metal detector (24) for the presence of a metallic foreign body (39), in order to check whether the original alarm was correct or false. If the alarm is triggered a second time, then the operator knows that a metallic foreign body (39) is, in fact, present and has to be removed. If the second alarm is absent, then the harvester (10) can be switched to the forward direction again without danger and the first alarm ignored. <IMAGE>

Patent DE-3419713-A1 (DE)
Title: Combustion engine with rotating drums
Inventor: ULRICH JAKOB DR
IPC: F02B53/04
Filed: 1984-05-26
Abstract: This relates to a combustion engine with rotating drums. The drums (T2 to T5 sheet 1) have wedge-shaped recesses (a). At each explosion in the ignition chamber Z one flap (K1 and K2 sheet 1) is forced into each of these recesses. The surface with the 3 arrows is thereby freed for the explosion pressure and the other surface protected. The pressure can therefore only result in one rotation of the drums. The drums (T1 and T6 sheet 1) form the swept volumes HU. Due to their rotation the content is forced into the ignition chamber with the aid of the flap KL. The exhaust gases at B fig. 1 are expelled and forced out by rotation of the drums. All axes A are connected to one another by gears. The height of the drums and the size of the recesses and the ignition chamber/swept volume ratio are variable. This engine may be used like any conventional combustion engine. <IMAGE>

Title: Prestacking unit for sheet feeders
Inventor: DANNEMANN GEORG-DIETRICH
IPC: B65H1/26
Filed: 1984-06-19
Abstract: The invention relates to a prestacking unit for flat pile feeders with a raised stacking table. It is the aim of the invention to save operating time by prestacking sheets and then loading the flat pile feeder with a raised stacking table, and to make substantial use of the possible stacking height. According to the invention, a prestacking unit takes the form of a mobile unit with a pile changing plate and is designed to be insertable directly above the stacking table of the folded sheet feeder. Stationary guides interact with wheels and/or guide rollers for the required positioning of the pile. Prepositioning of the pile on the pile changing plate is carried out by means of an angular stacking device known per se while the machine operates. The time it takes to change piles is reduced by using the prestacking unit. <IMAGE>

Filed: 1984-07-27
Abstract: In the production of joined weldments, the workpieces are assembled after only partial machining and then heat-treated together for hardening their surface, the weld gap formed by their contact surfaces being covered beforehand by an agent, which prevents carburisation of the contact surfaces, as a preparation without machining for welding by electron beams or laser beams following the heat treatment after individual machining of the workpieces has been completed.
Patent DE-3428708-A1 (DE)
Title: Device for the adjustment, proportional to an electrical input signal and independent of the load, of a control valve for a control mechanism
Inventor: BARTHOLOMAEUS REINER DIPL ING
IPC: F16H61/662
Filed: 1984-08-03
Abstract: A proportional magnet, the armature of which is forced into a basic position by a spring provided on the opposite end of the valve part serves for the actuation of the adjusting device. In the basic position the control mechanism has a certain operating state, for example a minimum possible transmission ratio, and from this basic position the armature is drawn back against the spring force into a control area as the input current increases. The arrangement of the spring makes a fluid connection between the valve part and the spring chamber essential. For this purpose the magnet ram, which transmits the force of the armature and of the spring to the valve part, is designed as a tube which is led on both sides of the armature in bearings on the housing side. This results in an armature chamber, which is sealed off from the valve part and the spring chamber to prevent dirt getting in. The fluid displaced in the armature chamber during the armature stroke also determines the hydraulic damping of the magnet. <IMAGE>

Title: Flat exhaust catalytic converter housing with uniform rate of flow
Inventor: GEUER ERNST
IPC: F01N3/28
Filed: 1985-04-17
Abstract: The invention relates to a housing design for exhaust catalytic converters, which deflects the exhaust gases in order thereby also to heat the carrier matrix from outside more rapidly and uniformly, as a result of which the "light-off temperature" is attained more rapidly, especially in the case of cold starting, idling and the lower partial load range. This housing construction also results in a uniform flow through the carrier matrix over its entire cross section, which brings with it an increase of the conversion rate and a longer working life. In addition these uniform pressures over the cross section allow the entire catalytic converter assembly to be designed very flat, which offers particular advantages for subsequent fitting to old vehicles. The improved heating behaviour can also be utilised in order to shift the catalytic converter more towards the "cold end". A further possibility stems from the possible perforation of the side wall of the deflection pot, which also allows the catalytic converter to become a silencing element. <IMAGE>
