Patent DE-3715926-A1 (DE)
Title: Apparatus for slipping valve bags onto the filling connection or filling connections of a packaging machine
Inventor: MITTELBACH HELMUT
IPC: B65B43/26
Filed: 1987-05-13
Abstract: Satchel-type valve bags made of plastic with relatively low inherent stability cannot be stacked with a straight edge. The invention is to ensure that each bag to be taken off from a stack is in the same position relative to a suction device separating the bag. For this purpose, a table (11) for receiving a bag stack (12) is movable transversely to the side edges of the bags. Via a controlled drive, after the uppermost bag (12a) has been taken over by the suction device (10), the table (11) is moved into a basic position and thereafter is moved into a position such that the filling orifice (12b) of the uppermost bag (12a) is located in a predetermined desired position relative to the suction device (10). The movement of the table (11) is regulated via a light-beam sensor (24) which records a control mark (23) made on the bag. To press down the bag stack (12), there are provided on the suction device (10) press-down strips (19) which are moved as a result of the movement of the table (11). Moreover, they can be moved out of the region of the suction device (10) by means of a piston/cylinder unit (21). The apparatus according to the invention can be used particularly in in-line packaging machines. <IMAGE>

Title: Method for the protection of an exhaust catalytic converter of a multi-cylinder internal combustion engine with applied ignition
Inventor: VOGT RAINER DIPL PHYS DR
IPC: F02D41/00
Filed: 1987-07-23
Abstract: In a method for the protection of an exhaust catalytic converter of a multi-cylinder four-stroke internal combustion engine with applied ignition and fuel injection into selected cylinders, a non-firing cylinder is determined by measuring the instantaneous speed of rotation of the crankshaft. Since the increase in the speed of rotation after a non-firing cylinder is lower than after firing cylinders, it can thereby be determined whether a cylinder has fired or not. By assigning ignition pulses to the individual cylinders, it is possible to determine the non-firing cylinder to which no fuel is fed during the succeeding working cycles. This ensures that the exhaust gas does not contain unburnt fuel which can burn in the catalytic converter and damage or destroy it.

Title: Method for determining the nuclear magnetisation distribution in a layer of a region under examination and NMR tomograph for carrying out the method
Inventor: MACKINNON GRAEME COLIN DR
IPC: G01R33/56
Filed: 1987-09-02
Abstract: The invention relates to a method for determining the nuclear magnetisation distribution in a layer which yields very short echo times. Each sequence of this method comprises, in this case, at least two part-sequences of which one comprises a selective 180@ radio-frequency pulse and a non-selective radio-frequency pulse following thereon, and the other comprises a corresponding non-selective radio-frequency pulse. The resulting FID-signals are superimposed on each other in such a way that the components of the FID-signals resulting from the nuclear magnetisation outside the layer compensate one another. Since the non-selective radio-frequency pulses are relatively broad-band and can therefore have a short period, the result is short echo times and, consequently, a good signal-to-noise ratio. <IMAGE>

Abstract: It is known to link handball goals (1) to extension arms which, in turn, are linked to a gymnasium wall so that, in conjunction with a cable drive acting on the goal frame, the handball goal (1) can be folded against the wall and, in this case, is situated at a height depending on the length of the extension arms. If the respective gymnasium is also used for football, the football goals (2) have to be set up and dismantled manually. By means of the device according to the invention, football goals (2) are linked via extension arms to receiving rails (14) which, in turn, are guided vertically in a slidable manner in guide rails (13) on the gymnasium wall. The football goal (2) can thus be stored at a height on the wall which allows the simultaneous storage of the handball goal (1). Both the handball goal (1) and the football goal (2) can be moved by means of special cable drives between a lower position, set up on the gymnasium floor, and an upper position situated on the wall. <IMAGE>

Title: Process for the production of undoped and fluorine-doped quartz glass
Inventor: HEITMANN WALTER DR ING
IPC: C03B37/014
Filed: 1988-10-15
Abstract: Quartz glass has hitherto usually been produced from silicon tetrachloride at very high temperatures by the CVD process. These glasses contain a high chlorine ion concentration and metallic impurities in the base material. Quartz glass produced by the novel process has a very low concentration of chlorine ions and metallic impurities and thus has lower attenuation in the UV region. The novel process operates at lower temperatures and does not allow any toxic compounds to be formed. The starting material used is high-purity silane (SiH4), from which the quartz glass is obtained by the OVD and VAD processes. Subsequent treatment in a chlorine gas/helium atmosphere reduces the OH content.   Quartz glass for optics and fibres for wavelengths below 600 nm.

Inventor: EBERHARD GUENTER DIPL ING DR
IPC: F16F13/26
Filed: 1989-01-28
Abstract: An elastic mounting comprises an elastic rubber spring member (3) located between two connecting members (1, 2) in order to support a vibrating load, whose vibration spectrum includes both low frequency and high frequency vibrations, in particular motor vehicle engine mountings. In parallel with the spring member (3) is fitted an electrostrictive or magnetostrictive actuator (4) in such a way that one face thereof (4.2) is rigidly coupled to a connecting member (1 or 2) of the spring member (3) while its other face (4.1) is connected to the other connecting member (2 or 1) via a closed static decoupling hydraulic system (11, 12). A sensor detects the alternating forces, alternating accelerations or vibrational displacements due to the vibrating load (L) and is connected to the actuator (4) via an amplitude and phase regulator and amplifier, wherein the regulation is so designed that the actuator (4) minimises the alternating forces, alternating accelerations and vibrational displacements applied to the sensor. The sensor may instead detect a characteristic parameter of a moving part of the vibrating load such as the angular position and/or rotation speed of an engine crankshaft. <IMAGE>
