Title: Pile cutting unit - has number of closely packed thin bodies to press material towards spiral cutter for fine patterning
Inventor: KURATA YOSHIHARU
IPC: D06C23/02
Filed: 1992-04-02
Abstract: The shearing appts. to cut the piles of a pile material, has a number of units each with a thin main body moving vertically in a slit in the unit block. The body has an integral thick headpiece to press the under layer of the material towards the spiral cutter. The thick head pieces are arranged next to each other, without intermediate gaps over the whole axial length of the spiral cutter. The lower section of the thin main body has an integral leg, displaced from the legs of neighbouring bodies. A cylinder mounting block, below the unit blocks, has piston rods for each leg, operated by pneumatic cylinders. USE/ADVANTAGE - The appts. is an arrangement of a spiral cutter and a cutting blade to cut piles between them at the under layer of a pile fabric to give a fine design pattern. As the units are close together, a fine patterning can be executed, with flexibility to work along long and short piles from materials for blankets to coverings for vehicles. The piles can be cut in two stages if required.

Title: Fully recyclable shaped lining e.g. for car interior or boot - consists of top covering of polypropylene@ fabric heat-bonded on to at least one suitable substrate of non-textile polypropylene@
Inventor: EXNER-EWARTEN DETLEV ING GRAD
IPC: B29C43/18
Filed: 1992-04-08
Abstract: A shaped lining, partic. one for inside cars, has at least one fabric cover layer and a thermoplastic non-textile stable substrate; both these two layers plus any further layers are made of non-crosslinking polypropylene.

Its polypropylene fibres are designed to have low shrinkage after shaping, and to have high thermal stability and low sensitivity to light when in serivice. It is bonded to a polypropylene base which neither is nor can be foamed but is therefore solid material of thickness 0.5-5.5 mm. The base layer is pref. selected to have the desired stiffness, sound absorption, toughness and stability. The top cover layer is pref. an isotactic polypropylene with Vicat softening pt. above 125 deg. C. The two layers are heated so as to fuse the surface of one into that of the other. The structure of the prod. can have three or more layers if desired.

Title: Mechanical voltage control for permanent magnet generator mechanical voltage control - varies strength of magnetic field by sliding magnetic plates of two plate rotor generator which can move radially w.r.t. each other
Inventor: STROBEL ULRICH
IPC: H02K21/24
Filed: 1992-07-20
Abstract: In the generator (2) with axial magnetic flux the two magnet plates (4, 6) rotate at both sides of the stator (8). The latter has an iron core and spools. The magnets (10, 12, 14, 16) lie exactly with the north poles opposite north and the south poles opposite south. Thus, the flow of the magnetic force lines through the spools (18, 20) from the magnetic fields of the plate (4, 6) is optimal. If the magnet plates (4, 6) are radially displaced with respect to each other, the field strength of the magnetic force lines changes accordingly. The field strength which acts on the individual spools is reduced as the plates (4, 6) move towards each other and the induced voltage is thus reduced. ADVANTAGE - Inexpensive, compact and lightweight. Can be used for all power ranges. Allows step-free control. No electric interference pulses with pneumatic or hydraulic control. No additional loss.

IPC: C23C4/134
Filed: 1992-08-07
Abstract: (A) Surface treatment of a solid body with a short duration pulse of high energy and density material is carried out by (a) passing energy from an energy store to an energy converter in which it is converted to an energy carrier in the form of a gas, liq., and/or solid for acceleration towards the solid body surface, and (b) impinging the pulse on the solid body surface for interaction with the extremely thin outer surface layer to effect structural and/or compositional modifications without affecting the rest of the solid body.     In a similar process, the energy carrier and/or additive, acclerated by the energy carrier, impinges on the solid body surface to create new matter which is then sepd. and recovered in isolated form. Appts. for carrying out the processes is also claimed.

Title: Method for determining the turn-on times of the switches of an n-phase pulsed current-controlled invertor
Inventor: LOESEL THOMAS DIPL ING
IPC: H02M7/5387
Filed: 1993-04-10
Abstract: In the case of pulsed current-controlled invertors, the natural frequency of the filter and harmonics of the fundamental occur in the AC circuit when using known methods for generating pulse patterns. The method according to the invention leads to severe attenuation of the natural frequency of the filter and harmonics of the fundamental. By superimposing the current ix1, flowing on the AC side without the action of a converter, and the direct current ix2, connected to the AC side by the converter, within a time interval tint = t2 - t1, turn-on times are calculated in such a way that a required desired value of the alternating current is reached. Sinusoidal or other waveforms are simulated by means of the desired current value. The method is suitable for single-phase or multi-phase pulsed current-controlled invertors. <IMAGE>

Title: Process for time-dependent control of a metering unit for fluid components and apparatus for carrying out the process
Inventor: KULICKE WERNER MICHAEL PROF DR
IPC: B01J4/00
Filed: 1993-06-07
Abstract: The invention relates to a process for time-dependent control of a discontinuous (batch-operating) metering unit for fluid components in which, optionally, an adjustable or non-adjustable metering valve is connected by means of a metering line to a metering pump. By means of a measuring device of a capillary viscometer type, when the metering unit is operated, the volumetric flow rate of the fluid is measured intermittently from the pump data and the pressure difference between the outlet of the metering pump and the final section of a dimensionally stable section of the metering line having a constant diameter and connected to the outlet of the metering pump. Taking into account the geometric dimensions of the dimensionally stable section of the metering line, the pressure difference between inlet and outlet of the dimensionally stable section of the metering line, the elastic portions of the pump and of the system and the volumetric flow rate transported, rheological characteristic data are determined. These characteristic data are compared with stored theoretical curves for shear strain and theoretical curves of the first normal stress differential N1 and theoretical flow curves of fluids corresponding to the fluid transported. If the actual values deviate from the theoretical values, the open throughflow cross-section of the metering valve and/or the volumetric flow rate is adjusted until the measured actual values of shear rate, shear stress and shear viscosity agree with the theoretical values.

Title: Device for detecting (measuring) a rotary movement
Inventor: MACH JIRI
IPC: G01D5/16
Filed: 1993-07-22
Abstract: A device is presented for detecting the rotary movement of a body by means of a sensor which responds to the variation of magnetic fields. A Hall generator (7) is particularly suitable as the sensor in this case. It is used in order to detect the revolutions of the worm (1) of a worm gear (worm drive). For this purpose, the Hall generator (7) is arranged with a magnet (8) in a sensor housing (4). The sensor housing (4) is plugged into a housing which encloses the worm gear. In this case, the sensor housing (4) is arranged such that the Hall generator is located immediately next to the tip circle (addendum circle, crown circle) (3) of the worm. The effective surface of the Hall generator is substantially smaller than the lead (pitch) of the worm. The worm itself consists of magnetisable steel. The worm thread is located directly in front of the Hall generator only once per revolution of the worm, so that here a small air gap having correspondingly large magnetic inductions is set up. The Hall generator is located in front of the indentation region between two thread segments in all the other angular positions of the worms. The air gap is correspondingly larger. A corresponding reduction in the magnetic induction is set up. This change can be detected by the Hall generator. The varying Hall voltage serves to evaluate the rotary movement of the worm (1). <IMAGE>
