Title: Method for reducing the temperature response of a tuned circuit, and an oscillator which is compensated in accordance with this method
Inventor: BECKER WOLF-JUERGEN PROF DR
IPC: H03B5/12
Filed: 1985-04-15
Abstract: The invention relates to a method for compensating for a temperature response of an LC tuned circuit, the tuned circuit quality being kept constant by means of a current through a second coil which is coupled in an opposing series connection to the tuned circuit coil. This current is controlled by the impedance loss of the second coil such that a change in the tuned circuit quality resulting from changes in the impedance loss of the tuned circuit coil is compensated for. Possible oscillator circuits using this temperature-compensated tuned circuit are specified, in the case of which the second coil is used as part of the feedback network. The use of such temperature-compensated oscillators is particularly advantageous in inductive proximity initiators and proximity sensors.

Title: Process for the regeneration of used mercerising liquor
Inventor: MAURITZ MANFRED
IPC: D06M11/38
Filed: 1985-04-23
Abstract: The regeneration process comprises the steps of evaporation of the used mercerising liquor in a single- or multi-stage evaporator and the removal of the impurities absorbed during the mercerising process by prior treatment of the liquor with oxidising agents. Whereas until now the addition of the oxidising agents was performed following the evaporation, it is now proposed that the oxidising agents are added during the evaporation of the liquor at a position within an evaporator stage or between two evaporator stages in which the liquor has a concentration of about 20-50% by weight of NaOH and a temperature of about 60-140 DEG C, and that the removal of the impurities from the evaporated liquor is carried out subsequently. As a result, the effectiveness of the oxidative treatment is significantly increased.

Title: Headbox for a papermachine
Inventor: DAHL HANS DR ING
IPC: D21F1/02
Filed: 1985-07-19
Abstract: In a distribution box (1) of the headbox for a papermachine, an even hydrostatic pressure along the direction of flow (F) of the fibre material suspension is obtained by providing, in the longitudinal direction of the distribution box (1), a flexible membrane (11) which separates a part space (12) filled with a stagnant fluid, for example an incompressible fluid, from the interior (13), taking the flow of the suspension, of the distribution box. With the headbox in operation, the flexible membrane (11) bends in such a way that the flow cross-section along the length of the distribution box is modified in such a way that the same hydrostatic pressure is automatically established everywhere. In this way, better evenness of the paper produced across the web width can be achieved in the papermachine, the distribution box being easy to produce simply and cheaply from flat sheet metal parts and having an improved mechanical strength even under relatively high pressures of the fibre material suspension. <IMAGE>

Title: Interior lighting arrangement in large vehicles for carrying passengers, in particular buses
Inventor: BETZ HANS-WERNER
IPC: E04F11/18
Filed: 1986-09-06
Abstract: In an interior lighting arrangement (1) in large vehicles for carrying passengers (aircraft, watercraft or land vehicles), lighting devices (10) in the form of strip lights or fluorescent tubes, are installed in the region of the luggage rack (3) at the top of the vehicle with a handrail (4) approximately at the height of the actual rack in the region of the vertical luggage compartment side walls or supports (5) directly behind the handrail (4) pointing slightly inwards and upwards and extending in the longitudinal direction of the vehicle. The lighting devices shine an indirect light, after reflection on the support (5), into the interior of the vehicle in such as manner that it is dazzle-free for the vehicle occupants. Since the lighting devices protrude beyond the support width within the modular pattern, the adjacent luggage compartments (6, 7) are illuminated at the same time. In the longitudinal region between the individual, abovementioned lighting devices (10), there are further strip lighting or fluorescent-tube lighting devices (14) for direct radiation of light upwards in the direction of the interior of the luggage compartments (6, 7) or downwards in the direction of the interior of the vehicle (general interior lighting - in contrast to the emergency lighting device (10) for night journeys) (Figure 1). <IMAGE>

Title: Process and apparatus for winding webs of material to form reels
Inventor: DJORDJEVIC DRAGAN DIPL-ING
IPC: B65H27/00
Filed: 1986-11-05
Abstract: When winding webs of material to form reels by winding shafts, the rotational speed of the winding shafts is controlled by open-loop or closed-loop control means in such a way that, when the new beginning of the web is taken over, the circumferential speed of the winding shafts or of the sleeves arranged on them coincides with the speed of the web of material. At high web speeds, rotational speed ranges in which the winding shafts vibrate in the radial direction are passed through. To remedy this, before reaching the critical speed ranges, the winding shafts are brought into contact with supporting rollers, which release the winding shafts after passing through the critical speed ranges and the said winding shafts then take over the new beginning, which has been formed, of the web of material. The supporting rollers can form restricted guides for the winding shafts and, in the critical speed ranges, produce with the winder the forces of reaction for absorbing the radial vibrations of the winding shafts. The supporting rollers, the winders and the winding shafts may form damped vibrational systems which, in the critical speed ranges, have a high damping and damp the amplitudes of the radial vibrations to virtually negligible values.

Title: Process and devices for producing footwear with a sole of vulcanised rubber
Inventor: FERNIANI ALDO
IPC: B29D35/08
Filed: 1987-05-06
Abstract: The process consists in the production, in a first production phase, of an outsole by injecting vulcanisable rubber into a first press-mould assembly which has, in a first section, the shape of a sole to be produced, combined with a first lower ring of reduced cross-section which accommodates a wrinkling of the sole obtained in the injection operation. The second part of the press mould has a counter ring which is essentially analogous to and complementary to the first ring and it acts with a section which has the counter-mould surface of the outsole. The entirety of the first press-mould assembly operates at high temperature to allow the vulcanisation of the rubber to be brought about. After this operation of injecting, with the formation of an outsole, the press mould is opened and only the lower ring, to which the sole is joined at its periphery, is removed and introduced by means of a manipulator into a second press-mould assembly, where a shoe upper part attached to a mould part is provided and into which a joining intermediate sole is injected, either as two-component foam or as thermoplastic material. This second press-mould assembly operates at low temperature and is expediently thermostated. The transfer of the outsole from a first press-mould assembly at high temperature to a second press-mould assembly at low temperature is carried out with the transfer ...
