Title: Process for the cleaning of teeth and tooth cleaning  device
Inventor: MAURER WILHELM
IPC: A46B7/06
Filed: 1985-08-29
Granted: 1990-02-06
Abstract: Abstract a tooth cleaning device for optimal tooth cleaning comprises, on a U-shaped carrier (109), tufts of bristles (180), which are placed against the tooth using pressure bubbles (149) under equal cleaning pressure on both sides. With this arrangement the tufts of bristles (180) are fitted to individually self-positioning rocker arms (174, 178'), in order to also engage in the spaces between the teeth, which are difficult to access. With the aid of a further pressure bubble arrangement (147) using phase-shifted pulsating pressuri-sation     with reference to the pressure-generating bubbles (149), a wiping movement of the tufts of bristles (180) with cleaning pressure is generated in the direction from the gum towards the crown of the tooth, in counter-direction without bearing pressure on the tooth.

Abstract: ABSTRACT OF THE DISCLOSURE    Garments contaminated with radioactive, toxin, biological and/or chemical contaminants are deposited in a cleaning drum and the drum is agitated during a wash cycle.  A dry cleaning solvent is added to the drum during the initial wash cycle and then drained to a distillation means.  Within the distill-ation means, there is a neutralizing agent which deactivates the biological and toxin contaminants and chemically breaks down the chemical contaminants removed with the dry cleaning solvent from the cleaning drum.  Dry cleaning solvent is then continuously added to the drum during the secondary wash cycle and continuously removed from the drum.  After the dry clean-ing solvent is removed from the drum, and before it is pumped back to the drum, the dry cleaning solvent is filtered to remove remaining  trace  particulate  contaminants.   The  dry cleaning solvent  is  also passed through an adsorber where remaining trace chemical contaminants dissolves in the dry cleaning solvent are removed.  The garments are then rinsed by circulating contaminant free dry cleaning solvent through the drum.  After rinsing, the garments are dried by circulat-ing hot, unsaturated dry cleaning solvent vapor through the drum.

Abstract: ABSTRACT OF THE DISCLOSURE         A safe and inexpensive method of measuring blood flow in experimental animals using non-radioactively labeled microspheres is provided.  The microspheres may be comprised of a variety of materials, including latex and agarose, and may be labeled with colored dyes or by linkage to enzymes, plant enzymes being preferred because they do not occur naturally in an animal's system.  After injection and circulation of the microspheres throughout the animal's system, blood flow to particular tissue may be measured by counting the number of microspheres in the tissue sample, the initial number of microspheres in the animal's blood stream having been measured shortly after injection.  In the case of microspheres labeled with colored dyes, the spheres may be counted in tissue either after separation from the tissue or while still trapped in the tissue's capillaries.          Techniques for separating the microspheres from blood and tissue are also provided.

Abstract: ABSTRACT     A compact, high efficiency non-interruptive motor generator power system for generating and supplying to a load A.C. of a substantially constant voltage, the motor thereof being a synchronous A.C. motor energizable from a source of irregular and interruptible A.C. line power, the generator being capable of converting its rotational energy into the A.C. output for many seconds after interruption of the A.C. line power.  The power system comprises a high efficiency, synchronous permanent magnet A.C. motor and an A.C.  generator coupled to and driven by the motor.  Both the motor and generator have a high rotational inertia common rotor wherein an outer cylindrical shell contains motor and generator rotor elements of high permeability soft magnetic material with a surface layer of magnetizable permanent magnetic material, and in each stator is an excitation coil, energizable with A.C., having a pole piece adjacent a layer of permanent magnetic material whereby to magnetize the layer into a selected pattern of north and south magnetic poles.  The motor stator is within and encircled by the common rotor and has power windings producing a rotating magnetic field while the generator stator has windings for generating the A.C. power to the load during rotation of the so-magnetized rotor.  Both stators also have feedback windings.  In the motor stator, the feedback windings generate A.C. of a selected magnitude and phase which is conveyed by a resonant circuit to the excitation coil and there combined so as to provide energization thereof by A.C. of such strength and phase condition as to magnetize the layer of permanent magnetic material into the selected pattern.  In the generator, the A.C. generated in the feedback windings is conveyed by an electrical circuit to the generator excitation coil which will essentially neutralize any A.C. induced therein by the magnetic field as the speed changes through the synchronous speed.  At all rotor speeds, only single phase A.C. potential of a precise desited frequency, phase, and predetermined magnitude is generated and conveyed to the excitation coil of the generator, so that the magnetic poles are produced in the layer of the permanent magnetic material of a precise pattern and a desired magnetic flux strength so that the power windings thereof generate A.C. of a desired frequency and voltage regardless of speed variations.  The generator portion preferably comprises two or more stator sections having common power windings so that each generates identical single phase A.C. and the A.C. phases of at least on section can be phase-shifted so that when the A.C. output of all sections are combined, close control of the total A.C. voltage output is obtained.

Abstract: Abstract:          System for transmitting words that are protected by a combination of a block code and a convolution code, transmitter device for use in such system and receiver device for use in such system.           A system is described for transmitting data words composed of more significant bits and less significant bits. The less significant bits of a data word are, by means of matrix multiplication, encoded into a first redundant proto-code word. The more significant bits of a data word are by means of matrix multiplication, and different delays over respective numbers of recurrence times of the arrival of the data words encoded in a set of further redundant proto-code words. A code word is formed by means of modulo-2-addition of code words, so that for the less significant data bits a block code is realized, while for the more significant data bits a convolutional encoding is realized. In the decoding, the more significant bits are decoded by means of Viterbi decoding, while the Viterbi metric is determined from the deviation between the reconstructed contribution from the lower significant bits and the actually received contribution therefrom.

Abstract: ABSTRACT     Electrostatic coating blade and method of electrostatic spraying An electrostatic blade is disclosed having a slot extending the length of the blade and leading from a central duct to an outlet A surface made of non-conductive material extends in front of the outlet and terminates in a discharge edge which is spaced 0.05 to 4mm from the slot outlet In use, liquid is passed from the duct along the slot to the outlet where it collects as a bead. An electrostatic field is applied between the liquid at the slot outlet and the object to be coated which draws liquid along the non-conductive surface in a tapering stream and further causing the liquid to be discharged from the edge Because the stream of liquid reaching the discharge edge is very thin, very low liquid discharge rates can be achieved while still maintaining a uniform coating on the target object.

Abstract: ABSTRACT OF THE DISCLOSURE     In a method and apparatus for cutting a chain of longitudinally joined elongate products into pieces of a desired length, the chain of elongate products is intermittently fed by a feed unit through a first distance equal to the length of each piece to be severed, along a path through a detector and a cutting unit downstream of the detector and the chain is cut successively into pieces of the desired length at the cutting unit while the feed unit is inoperative.  As the chain is advanced, the joint portion of each adjacent pair of the elongate products is detected by the detector.  Upon detection of the joint portion, a control unit computes the number of prospective pieces of the desired length producible by severing from a longitudinal portion of the chain which extends from the present leading end of the chain toward the detected joint portion and terminates short of the detected joint portion.          When the computed number of pieces have been severed, the chain is advanced by a second distance until the detected joint portion is located downstream of the cutting unit.          The chain is cut to produce a severed piece including the detected joint portion which is received in a reciporcably movable container.

Abstract: IN-LINE FIBER OPTIC MEMORY Abstract of the Disclosure A fiber optic recirculating memory comprises a splice-free length of optical fiber which forms a loop that is optically closed by means of a fiber optic coupler. The coupler couples an optical signal input pulse to the loop for  circulation therein,  and  outputs  a portion of  the signal pulse on each circulation to provide a series of output pulses.   A pump source is  included to pump the fiber loop with a pump signal having sufficient intensity to cause stimulated Raman scattering in the fiber loop, and thereby cause amplification of the circulating signal pulse.        The    fiber    characteristics,    coupler characteristics,  and pump power are selected to yield a Raman  gain  which  compensates  for  the  total  round-trip losses in the fiber loop, so as to provide an output pulse train of constant amplitude pulses.  The invention may be implemented  utilizing  a  standard  coupler  with  a  pump signal modulation technique.  The pump signal is input to the loop as a series of pulses having a duration and a periodicity  chosen  to  prevent  overlap  of  recirculating pump pulses with  input pump pulses until at least two circulations  of  the  loop,  which  minimizes  pump  power fluctuations  and  will  therefore  enhance  output  signal stability.

Abstract: The invention aims to eliminate some of the work involved in hoisting the flag, taking it down, undoing the flag rope, folding the flag up, then taking the flag out again, connecting the rope and hoisting it. The invention is characterized by the openings in the top part of the flagpole and by the rope guide through the two openings. By pulling the flag rope (stage 1), the flag is drawn into the flagpole, where it can be stored. By pulling again in the same direction (stage 2), the flag is drawn out of the flagpole and in this way the flag comes to hang correctly, before stage 3 is carried out. By pulling in the opposite direction (stage 3), the flag is drawn in through opening B, up through the flagpole and out through opening A and comes to fly at full mast again. The invention is intended especially for those who use flags on a daily basis, for example businesses, institutions, ships, etc. <IMAGE>
