Patent DE-4221175-A1 (DE)
Title: Vacuum- or high-pressure pipe-connecting system - has profiled ring distorted only at rear end by union nut (2) to form holding and sealing portion
Inventor: LEHMANN KLAUS
IPC: F16L19/10
Filed: 1992-07-01
Abstract: The system is for pipes under vacuum or handling up to the highest pressures. The profiled ring (3) is distorted only at its rear end by the union nut (2) so as to form the holding and sealing portion. At the forward end, the ring can protrude only for a short distance, typically 3 to 4 mm. Inside the cone of the screwed union (1), and on this portion an interchangeable metal sealing washer can be mounted. There can also be an elastomer sealing ring behind the metal sealing portion (3b) of the profiled ring. USE/ADVANTAGE - The pipe and ring protrude for less distance inside the vacuum- or high- pressure union, with consequent easier installation and dismantling.
Patent DE-4221736-A1 (DE)
Inventor: LARSON BERND DR
IPC: C11D11/02
Filed: 1992-07-02
Abstract: When preparing powdered or granulated detergent composition having a high apparent density, an ulterior treatment is required in order to improve its solubility. For that purpose, the prefabricated powder or granulate having over 500 g/l apparent density is contacted while stirring with a liquid or solid, hydrophobic and/or water-insoluble component which is not a zeolite. The weight ratio between the prefabricated powder and the liquid or solid, hydrophobic and/or water-insoluble treatment agent is set between 20 : 1 and 2000 : 1.

IPC: C08G64/30
Filed: 1992-07-13
Abstract: The prepn. of aromatic polycarbonates of wt. average mol. wt. (Mw) 15,000-200,000 and OH end-gp. content below 250 ppm (I) from diphenols, carbonate diesters and opt. branching agents, comprises (i) transesterifying in the melt to give oligo-carbonates (II) of Mw 2,000-10,000 and OH end-gp. content 20-50 mol.% followed by crystallising; and (ii) solid-phase polycondensing the crystalline (II) in the presence of a boiling organic solvent (III) which acts as entraining agent for the cleavage prods. from polycondensn. but does not dissolve or melt the oligomer (II). USE/ADVANTAGE - (I) are used e.g., in the electrical industry and in motor vehicle prodn.. The process enables the removal of cleavage prods. from (II) without using large amts. of gaseous entraining agent and without the high cost associated with high vacuum processes (cf prior-art processes). In an example, a mixt. of 684.9g Bisphenol A, 661.3g diphenyl carbonate and 8mg Na bisphenolate was melted at 250 deg.C with stirring, then the pressure was reduced to 1 mbar over 90 mins. (with a continuous rate of distn.) to give an oligomer (II) of relative soln. viscosity (RSV) 1.080, which was crushed and crystallised from acetone. 20g (II) was heated with 180g undecane for 1 hr. at 180 deg.C and 7 hrs. at 200 deg.C in an appts. fitted with a reflux condenser and an extractor contg. 10g zeolite K-Y. The prod. was a crystalline, colourless polycarbonate of RSV 1.254 (0.5% in CH2Cl2).

Title: Fuel metering control system for IC engine - Has detectors for engine condition, acceleration demand (pedal position) and vehicle speed to control fuel enrichment
Inventor: VOGT BERNHARD DIPL ING
IPC: B60K26/00
Filed: 1992-07-17
Abstract: The patent describes the control of fuel metering for an IC engine, depending on engine speed, load and temp. and the acceleration demand. There are detectors for the engine variables and accelerator pedal position plus means for enriching the air-fuel mixture according to acceleration demand. This enrichment is dependent on vehicle speed, the sensitivity increasing with increasing speed. When a vehicle has stopped, or below a speed threshold of 4 km/h, there is a first enrichment threshold and a higher threshold for higher speeds. These thresholds are temperature-dependent and increase for increasing engine temp. However for low temps, the second threshold is independent of vehicle speed. ADVANTAGE- Fuel enrichment as function of vehicle speed as well as acceleration demand, thus improving vehicle's performance.

Title: Expanding gear for band winder - uses ball thread drive with freewheel and slip clutch for easier expansion and security against automatic resetting
Inventor: FECKER EUGEN
IPC: B65H18/04
Filed: 1992-07-17
Abstract: The cylindrical centre bore (9) of the main slider (5) is penetrated by a ball rolling spindle (10) of a ball thread drive (11) which is mounted rotatable directly or indirectly in bearings (14,15). A ball rolling nut (17) seated rotationally secured on the spindle in an inner recess (16) of the main slider transforms a rotation of the spindle into a longitudinal movement of the main slider. A freewheel (22) is attached on one side to the spindle so that the latter is secured against automatic rotation moving the tension jaws radially inwards. A slip clutch (24) is connected to the freewheel and its load holding movement can be lifted by operating the spindle in order to expand the expanding gear. USE/ADVANTAGE - The force applied to operate the expanding gear for a band winder is reduced, thereby avoiding expensive mechanical drives.

Title: Self correcting control for recycling exhaust gases in IC engine - provides variable return flow, analysis of engine operation with varying recycling and fail=safe control upon failure.
Inventor: FUJIMOTO SHINYA
IPC: F02M25/07
Filed: 1992-09-18
Abstract: The IC engine has a return duct with a solenoid valve to regulate the level of exhaust gas recycling to the inlet manifold (3).

The engine monitoring is in set intervals and is inhibited during rapid changes in performance to eliminate transient effects. The inlet manifold has a sensor (8) for the throttle (7) setting, a pressure sensor (6) and an injector jet (5) - all linked to the controller (19). ADVANTAGE - Self analysing control system; reduced emission products.

Patent DE-4324258-A1 (DE)
Inventor: BAUER ALFRED
IPC: H02K23/36
Filed: 1993-07-20
Abstract: The invention relates to a permanent-magnet DC motor having two rotation-speed levels, especially for driving domestic kitchen machines, as well as having a stator which is fitted with permanent magnets and having a rotor (9). At one end, the rotor has two commutators (8, 10) each having at least two commutator brushes (7, 11 and 13, 14 respectively) which are approximately diametrically opposite on a commutator (8 or 10 respectively), and, at the other end, it has two armature windings which are isolated from one another in DC terms and are connected to in each case one of the commutators (8, 10). The armature windings have approximately the same number of turns and the same wire cross-sections, using the same material selection. Furthermore, switching means are provided for connecting the commutator brushes (7, 11 and 13, 14 respectively) to an AC voltage mains power supply (1). The switching means consist of a bridge rectifier (5) and a switch (19). The two armature windings are electrically connected in series with one another and to the positive output (4) and negative output (16) of the bridge rectifier (5) via the commutator brushes (7, 11 and 13, 14). The switch (19) is connected between the connecting lead (12) which connects the two commutator brushes (11, 13), and one of the two AC voltage connections (17, 23) of the bridge rectifier (5). In consequence, the DC motor can be operated at two speed levels using simple switching means, without it being demagnetised and heated non-uniformly in the process. <IMAGE>
