Patent YU-24600-A (YU)
Title: Method of molding toothbrushes and apparatus for performing the method
Inventor: GERARD BOUCHERIE BART
IPC: B29C45/14
Filed: 1998-10-29
Abstract: In the proposed method of molding toothbrushes, a mold with relatively movable mold parts (14, 16) defining at least one molding cavity (20) corresponding in shape to a toothbrush body is used. One of the mold parts (16) has a brush head defining cavity portion with a plurality of holes (24) for partial penetration into the cavity portion of a like number of fibre tufts. Plasticized molding material is injected under pressure into the cavity (20). Pressure within the cavity is sensed during the injecting step. The injection is stopped when the pressure within the cavity exceeds a predetermined pressure value, thereby avoiding any leakage of molding material through the holes (24).
Patent AT-A152896-A (AT)
IPC: F27D13/00
Filed: 1996-08-27
Abstract: Waste (such as domestic garbage, industrial waste, and bulky refuse) or sewage sludge is pretreated by pyrolysis under an oxygen-poor atmosphere to provide solid pyrolysis residues and a pyrolysis gas. The solid pyrolysis residues are mechanically treated to provide a coarse fraction and a fine fraction. The coarse fraction is mechanically separated and fed to a metal bath reactor containing a metal bath and a liquid slag floating on the metal bath. The fine fraction entrained in a carrier gas is fed via a nozzle in order to carburize the metal bath. The carburized metal bath functions to reduce metal oxides from the liquid slag floated thereon, thereby purifying the liquid slag. At least a portion of the pyrolysis gas is used to smelt and heat the liquid slag.
Patent AT-A263089-A (AT)
Inventor: BERGER HUBERT DIPL ING
IPC: G01R31/34
Filed: 1989-11-16
Abstract: The invention relates to a method for measuring the mechanical torque on the shaft of an asynchronous machine supplied by a current or voltage rectifier with an intermediate circuit and coupled with a machine or engine or a test object, preferably an internal combustion engine. Values of the current (Id) and voltage (Ud) in the intermediate circuit of the rectifier (1, 2) are measured. The actual power (PKZ) in the intermediate circuit, averaged over a selected time-interval, is derived from these values. A modified rotary field power (P &cir&  &tilde& D) is derived by subtracting from PKZ all power losses (VWR) in the inverse rectifier (2) and the electrical and mechanical power losses (VASM) of the machine (3), with the exception of the rotor copper losses of the fundamental oscillation (VCu2,1). The modified rotary field power (P &cir&  &tilde& D) is divided by the angular frequency ( omega S) of the fundamental oscillation of the stator of the asynchronous machine (3), referred to the number of pole pairs (p), which can be derived from the electronic control and regulating system (4) of the rectifier (1, 2). This value is equated with the mechanical torque (Mm) reduced by the acceleration torque calculated from the moment of inertia (Jp) and the change in rotational speed (d omega m/dt). The advantage of this method is that the rotor copper losses of the fundamental oscillation, which are very difficult to determine because of their temperature dependence, can be neglected in the determination of the shaft torque.

Title: Central heating radiator with heat storage - uses low capacity coil embedded in concrete between two metal sheets
IPC: F24D11/00
Filed: 1983-03-15
Abstract: The method of forming a radiator panel for central heating uses only a small amount of water to form a good reservoir of heat. It uses sheets of metal with holes at suitable positions for the supply pipes. A copper coil is secured between the sheets and the space between is also filled with a mixture of sand and cement. The mixture is used to form a layer of concrete in which the coil is embedded. A double radiator with two face-to-face panels can be constructed with air circulated between them.

Abstract: An interdental toothbrush has a handle made from a mixture of a thermoplastic elastomer and a general purpose polypropylene. A twisted wire brush projects from the handle in axial alignment therewith. The toothbrush can be held within a loosely clasped fist, with one end of the brush held between a thumb and an index finger.

Les avantages de ce nouveau procédé sont nombreux : simplicité, réduction des risques de corrosion due à l'emploi de matériaux inattaquables, donc obtention de produits plus purs, absence de solvant, ce qui permet d'utiliser à production égale un réacteur de dimension rédui?e, et ne risque pas d'entraîner la participa-tion de ce solvant e n lui-même à la réaction, nécessitant une récu-pération et un purification co?teuse.  De plus, la bromation a lieu à température ambiente ou peu élevée et conduit à de hauts rendements.

Abstract: ABSTRACT OF THE DISCLOSURE               Changes in the electrical state of devices connected to a plurality of wiring terminals are detected and recorded by a data recording system programmed to evaluate the terminals singularly or in groups of various combinations.  A central controller is programmed to generate terminal address data, either singularly or in groups of various combinations, and these terminal addresses are applied to a cable driver that partially decodes the address data into one of several selected terminal groups.  The partially decoded terminal address data is applied to decoder/selectors for each of several major terminal groups wherein further decoding takes place.  Only one of the detector/selectors is activated by the partially decoded address data to further decode the address to identify a particular terminal or group of terminals.  Th? decoded data provides a control signal that actuates terminal gates for the selected terminals to couple a voltage at the terminals to a detector/ control.  The detector/control converts the voltage at the selected terminals into an electrical state code that is applied through the cable driver to the central controller.  Coupled to the central controller is a recorder or other readout device for producing a hard copy display presenting the electrical state of the selected terminals.

Abstract: Abstract of the Disclosure A small-mouthed container having a continuous resinous coating covering the interior of said container and end, said interior coating having a thickness less than about one mil and being free of low molecular weight organic matter, is dis-closed herein.  Typical containers are food and beverage con-tainers having cylindrical metal walls and circular disc-shaped ends.  The coating is typically a comestible coating having a thickness of less than one mil and having no occluded solvent therein.  Thermoset resinous coating are particularly useful.           A coating is applied by flowing a mixture of gas and fine resin particles through a nozzle into the vicinity of a plasma arc flame which at least partially melts the surface of said particles and propels said particles into a rapidly spinning container having one closed end.  A predetermined quantity of resin is pulsed through the nozzle to deposit on the interior of the container a uniform coating of resin par-ticles.  A cured coating can be obtained by introducing the particles into a plasma flame for a sufficient residence time to liquify substantially said particles and to impart sufficient energy therein that said particles cure upon said substrate without subsequent addition of energy.  Alternatively, the con-tainer coated with uncured particles can be heated in a curing oven for a period and at a temperature sufficient to produce a cured resinous coating.
