Title: Vorrichtung zum umschalten eines mechanischen schaltmittels zwischen einem ersten schaltzustand und wenigstens einem zweiten schaltzustand
Inventor: MEYER JOERG
IPC: F16H61/28
Filed: 2001-09-05
Abstract: Die Erfindung betrifft eine Vorrictung (1) zum Umschalten eines mechanischen Schaltmittels zwischen einem ersten Schaltzustand und wenigstens einem zweiten Schaltzustand, mit einem mit dem Schaltmittel gekoppelten Stellglied (4) zum Umschalten zwischen den Schaltzuständen, wobei das Stellglied (4) über eine Kuppelvorrichtung (5, 6, 7, 12) mit einem Steuerglied (5) gekuppelt werden kann. Das Steuerglied (5) kann von einer Antriebsvorrichtung (8, 9, 10 11) angetrieben und die Kuppelvorrichtung (5, 6, 7, 12) über ein elektrisches Signal betätigt werden. Im Falle des Ausfalls des elektrischen Signals wird die Kuppelung zwischen dem Stellglied (4) und dem Steuerglied (5) von der Kuppelvorrichtung (5, 6, 7, 12) freigegeben, so dass diese beiden Glieder (4, 5) voneinander entkuppelt sind. Für eine Rückstellung des Schaltmittels in den ersten Schaltzustand bei Ausfall des elektrischen Signals ist mit dem Stellglied (4) und einem Widerlager (14) ein Federmittel (13) gekoppelt, welches im zweiten Schaltzustand hinsichtlich des Stellgliedes (4) derart gespannt ist, dass im Falle einer Entkuppelung das Schaltmittel über das Stellglied (4) von dem Federmittel (13) in den ersten Schaltzustand zurückgeschaltet wird.

Bei einer direkteinspritzenden Brennkraftmaschine (18) kann einem geforderten Drehmoment entsprechend eine bestimmte Anzahl an Brennräumen (4) mit einer einem Homogenbetrieb entsprechenden Füllung und die restlichen Brennräume (4) mit einer einem Schichtbetrieb entsprechenden Füllung betrieben werden.
Patent WO-2004016926-A1 (WO)
Inventor: GAESSLER HERMANN
IPC: F01L9/20
Filed: 2003-06-18
Abstract: The invention relates to a method for the control and/or regulation of a constant voltage converter (13) for at least two electromagnetic valves (11, 12) of an internal combustion engine, especially an internal combustion engine in a motor vehicle.  A current, which is produced by the constant voltage converter (13), is supplied to each of the valves (11, 12).  It is determined when the total supplied currents of the valves (11, 12) represent a high load for the constant voltage converter (13).  If this is the case, the constant voltage converter (13) results in an improved processing of the higher load.

Title: Storage material for the recording of - high frequency signals
Inventor: CATJETAN SCHIELE DR DIPL-CHEM
IPC: G03C1/685
Filed: 1968-10-02
Abstract: Material works by colour change of spiropyranes, the storage material contng. beside the spiranes, a substance that is split into radicals by the recording radiation (Parent DT. 1274655). Spiropyranes are specifically substd. so that the substituent is adjacent the phenolic OH-grp. of the coloured salt of the spiropyranes formed during irradiation, and facilitates thereby an intramolecular H-bridge with formation of an additional stabilising ring system. The storage material gives improved permanence of recorded signals achieved by increased stability of the coloured forms.

Title: Greeting card with a decorative printed plastic-film
Inventor: EDWARD DUDDINGTON ALLAN GEORGE
IPC: B42D15/04
Filed: 1968-12-06
Abstract: Greeting cards or similar presentation cards comprising a supporting carton sheet or like paper material carrying on one side a separate layer or foil of transparent or translucent plastics, applied by means of a pressure adhesive, with a decorative print on the surface contacting the support sheet yet visible through that surface. A non-plastified PVC foil is taken, and pressure adhesive is first applied to a siliconised paper which is adhered to the support sheet. The aid adhesive is of a type clinging to the PVC upon the removal of this foil which, therefore, can be pressure-applied, as a decoration, to other surfaces. The foil removal can be rendered easy by letting it overreach a marginal part of the sheet e.g. by cutting off a corner of said support sheet.

Title: Thermoplastics fleece sack - with heat/pressure seams - for perishables
IPC: B65D30/00
Filed: 1970-06-03
Abstract: Thermoplastics fibres laid out in a random fleece arrangement are sprayed with latex, thus fixing them in position. Heat and pressure are then applied to form cross seams made up from molten or fused fleece material. Polyamide, polypropylene or polyester are used as thermoplastics, preferably 2 g dry latex per m2 surface area. A calendar stage at 135-165 degrees C can be interposed between spraying and seaming. The seam rupture strength obtained should be 8 kg/cm, with surface weight of the sack fleece between 50 and 200 g/m2. the sack can "breathe" and is thus suitable for perishables.

Filed: 1971-09-28
Abstract: Reforming is carried out as in DT 2022076, extended to cover use of at least 2 successive reforming zones, with a reduced proportion of oxidising gas (steam and/orCO2). Part of the hydrocarbon charge is fed to the first zone and the remainder passed with the gas from the first zone through the succeeding zones.

The gas emerging from each zone is mixed with fresh charge in amt. and at temp. necessary to give a mix temp. of at least 648 degrees C, (pref. 704-815 degrees C). The gas obtained consists of at least 80% hydrogen and CO in a ratio of 3:1 to 4:1, suitable for hydrocarbon synthesis or iron ore reduction without further treatment or re-heating.
Patent DE-2155460-A1 (DE)
Title: Powder/gas cutting torch - with automatic powder shut off in event of ignition in nozzle
Inventor: KUSHIZAKI TAKESHI
IPC: B23K7/08
Filed: 1971-11-08
Abstract: A gas cutting torch using acetlyene, oxygen and a powdered metal esp. steel has a safety device that automatically cuts off the flow of powder if ignition should take place inside the burner nozzle. If this happens, the build-up of oxide restricts the flow, thereby creating a back pressure in the pipe to move a piston in the control valve to stop the flow of powder from the container. A separate control valve can be used for the same purpose so that the torch can be used for ordinary welding and cutting.

VIB components (pref. 1-10% wt. Ni or Co and 4-30% wt.Mo or W components) on silica carrier (alumina contg. 10-90% wt. silica) and may include crystalline aluminosilicate. Pref. process is also operated such that max. temp. of stage (b) is at least 50 degrees F lower than max. temp. of stage (a). Process allows the second stage conventional catalyst to operate on relatively low sulphur feed and thus maintain its activity.

Title: Fluid pressure control valve - has sliding component of cross-section no greater than jet outlet
Inventor: DICK HEINRICH
IPC: F16K31/06
Filed: 1973-08-04
Abstract: The valve supplies a pressure depending on a datum value, having a jet communicating with the inlet and directly connected to a release chamber of larger cross section, while a component moving in the axial direction of the jet varies the cross section of the latter, being thrust in the open direction by the pressure in the jet, and in the closed direction by a force dependent on the datum pressure. The cross sectional area of the sliding component at the jet end and also at the guide end is at the most equal to the jet outlet cross section, and from the jet end either tapers towards the guide end or remains constant.

Title: Inductive signal transmitter on track - has symmetrically arranged parallel open core solenoid and conductor loop system
Inventor: HERMANN WALTER DR
IPC: B61L3/22
Filed: 1973-12-13
Abstract: Electrical signals are transmitted inductively between a fixed location in the track and the travelling vehicles. The vehicle clearance is ensured by transmitting and receiving systems which are coupled to an electrical conductor placed along the line by means of a solenoid with a 'U' shaped core. Each fixed location has a conductor loop which is symmetrical with a conductor in the vertical plane of symmetry. The combined transmitter and receiver system is coupled to the solenoid which has at least three pole shoes which form a parallel system with the conductor. The gap between the two outer pole shoes is greater than the width fo the loop. This system ensures correct clearance between the vehicle and track and it is also used for local information transmission.
