Patent DE-4104057-A1 (DE)
Inventor: ADAMS JUERGEN DIPL ING
IPC: G07B13/08
Filed: 1991-02-11
Abstract: The invention relates to a method and device for checking the tariff setting times in a taximeter or odometer, which are dependent on a clock (rtc = real time clock). The method of the invention consists in that, in a taximeter to be checked, relevant time advancements, preferably a time advancement by one minute at a time, are to be accelerated maximally by starting a maintenance program, in such a way that a time sequence of an evaluating program is made to initiate tariff-setting functions in a time-compressed form. The device for checking the tariff setting times in a taximeter of the kind described above is characterised in that a stoppage of an accelerated time sequence is marked by an acoustic message, and each stopping of the accelerated time sequence is counted by means of a counter. <IMAGE>

Patent DE-4115473-A1 (DE)
Inventor: BAUER ALFRED
IPC: H02K9/04
Filed: 1991-05-11
Abstract: Household appliances having an electric collector driving motor (2) the winding of which is cooled by a fan (5) driven by the same driving motor (2) are known. According to the invention, the fan (5) is driven by its own electric, d.c. motor (4), having also a collector. The fan motor (4) and the driving motor (2) are electrically interconnected in such a way that with an increasing load moment at the driving motor (4) the armature current of the fan motor (4) also increases. On the contrary of known household appliances, the driving motor (2) is thus more strongly cooled when its heat emission increases and is less strongly cooled when its heat emission abates.

Inventor: SEIDEL REINHARD DR
IPC: C23G5/06
Filed: 1991-09-05
Abstract: A combined process is disclosed for cleaning and corrosion proofing tools made of iron or steel, soiled in particular with oil, grease and/or rust, by steeping in an aqueous acid mordant the soiled metal surface and by phosphatizing the cleaned metal surface with an aqueous phosphoric acid solution that may also contain additives for controlling the formation of the phosphate layer. The process is characterized in that at least during phosphatizing an aqueous bath solution is used, containing dissolved phosphoric acid together with an emulsified, disperse organic liquid phase on the basis of oleophilic esters, oleophilic ethers and/or oleophilic alcohols, as well as emulsion-stabilizing surface-active compounds. Preferably, the process is carried out during the mordant step as well in the presence of the oleophilic ester-, ether- and/or alcohol-based emulsified organic liquid component. The process may be carried out in a single step or in two separate mordant and phosphatizing steps.

Title: Pneumatic false twist spinning - has texturising nozzle with offset alignment to output roller pair
Inventor: LANG KURT
IPC: D01H1/115
Filed: 1992-01-22
Abstract: Airjet false twist spinning equipment has drafting rollers with an output roller pair. The airjet unit has an air extraction section, of which the nozzle fits snugly into the wedge towards the nip of the output roller pair. The central projection line through the nozzle is approximately at right angles to the line across the centres of the output roller pair, and offset from the nip by a specified distance. Pref. the yarn is carried through the airjet false twist unit where a compressed air supply and a series of angular jets (9) twists the external fibre around a core. The suction through the yarn in the section, rearranges the loose fibre ends to improve the quality of yarn as it passes through the output roller nip of the roller pair. The nozzle is designed to lie close to the surface of the rollers and the drive roller is made larger than the counterpart. ADVANTAGE - The twisting action of the airjet equipment is desinged to ensure that all ends of fibre are firmly held. There is a distinct improvement in quality of the yarn by aligning the nozzle of the air extractor in the offset position.
