Patent DE-3717020-A1 (DE)
Title: Process for the opening-free production of pipe insulations, and cold-insulated pipeline
Inventor: WENNMANN MANFRED
IPC: F16L59/10
Filed: 1987-05-21
Abstract: For the opening-free production of pipe insulations or even of container insulations, the invention provides that the sheet-metal or plastic casing is fitted so that it forms chambers or partitions, that, in this arrangement, some of the tack and/or screw holes first of all remain unoccupied, and that the insulating material is then introduced in a fluid form, from that side of the chamber which is located opposite the free tack and/or screw holes, through an opening located at the uppermost point. In this arrangement, the opening is made in the partition wall, with the result that subsequently only those holes which are left for venting purposes and are later to be provided with a rivet or screw have to be sealed. The effective sealing, which can be further improved by drawing in an additional sheet as a vapour barrier, ensures extremely durable heat and cold insulation which is always effective. <IMAGE>

Title: Method for controlling the temperature of glow plugs in diesel engines and circuit arrangement for carrying out the method
Inventor: RABL HELMUT DIPL ING
IPC: F02B3/06
Filed: 1987-11-09
Abstract: A method for controlling the temperature of glow plugs in diesel engines is proposed. The flow of current to the flow plug (1) is switched periodically on and off in this method by pulse width modulation. During the switch-off pauses, the thermal voltage occurring at the glow plug (1) between contact electrode (4) and housing terminal (5) is determined as a measure of the instantaneous temperature of the glow plug (1). After the determined thermal voltage has exceeded a predetermined set value, a control process is initiated which keeps the determined thermal voltage as near to this set value as possible. Additionally, a circuit arrangement for carrying out the method is described. <IMAGE>

Patent DE-3806899-A1 (DE)
Inventor: SCHIRMACHER MANFRED
IPC: B67D7/34
Filed: 1988-03-03
Abstract: When filling tankers from fixed dispensing points, the problem arises, in particular when conveying environmentally hazardous liquids, that both the state of connecting lines requires constant monitoring and overfilling of the tank container of the said vehicle has to be prevented. To ensure these and other necessary safety measures, a monitoring device according to the invention is proposed, in which the filling level inside a container (1) is monitored by an overfill safety device, e.g. a PTC-thermistor system, which forms part of a substantially closed circuit, in which are integrated furthermore the electrically conductive connecting lines (11, 12), which in each case form the connections for filling and de-aerating the container (1), and a monitoring apparatus (18), through which the shut-off member (10) controlling the product flow can be actuated via a control apparatus (23). The connecting lines (11, 12) are attached, substantially electrically insulated, to the pipelines (6, 7) of the dispensing point, on the one hand, and to the corresponding connections of the container (1), on the other hand, resistors (13), by which these insulations are bypassed, merely ensuring the discharge of static electricity. The monitoring of the filling process is based on continuously checking the conductivity of the said circuit, the shut-off member (10) being opened or closed as a function of this checking.

Title: Method and device for laser-beam diagnosis
Inventor: KOCH ALEXANDER DIPL ING
IPC: G01P5/26
Filed: 1988-05-04
Abstract: A measuring arrangement is described which makes possible measurement of the speed of plasma particles in a plasma beam. Laser pulses are radiated successively into the plasma beam obliquely from the front and obliquely from behind, which laser pulses generate stray light in the plasma, to be precise at the same respective place, the stray light from the beam incident obliquely from the front being doppler-shifted with respect to the beam incident obliquely from behind. The stray light detection is carried out by means of a monochromator in such a way that the stray light signals are projected onto one of the two flanks of the transmission profile. In this way it is made possible to determine the doppler shift and thus the speed by measuring the intensity differences between the two signals. A reference signal detector having a broad-band monochromator serves for standardising the scattered light pulses, which may fluctuate, that is to say for standardising the intensity. The two laser pulse beams used are delivered by one pulse laser via a dye laser, switching-over being carried out via a piezoelectrically controlled prism.

Title: Drive arrangement
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C17/06
Filed: 1988-06-18
Abstract: A drive arrangement for an eccentrically driven mass (3) is described with a drive shaft (5), which drives the mass (3) by way of a first eccentric device (7), and with an auxiliary shaft (20) torque-synchroconnected to the drive shaft, the auxiliary shaft constraining the mass (3) by way of a second eccentric device (21) arranged at an interval from the first eccentric device (7). At the same time, the second eccentric device acts on the mass (3) by way of an elastic bearing bed (25). In order to now prevent or at least reduce stresses of the guide bearing caused during operation due to the deflection of the drive shaft (5), it is proposed that the eccentricity (eNW) of the second eccentric device (21) be designed greater than the eccentricity (eAW) of the first eccentric device (7) by at least a part of the amount of the maximum deflection of the drive shaft (5) resulting in operation in the area of the mass (3). <IMAGE>
