Title: A non-tactile control arrangement
Inventor: STEWART MARK NORMAN
IPC: G06F3/042
Filed: 1993-04-02
Abstract: The invention provides a non-tactile control arrangement including an array of light sensors 5, an array of light emitters 4, each one of which is adapted to illuminate, and thereby cause an output signal to be generated by, at least a respective one of the array of light sensors, detection means for detecting the output of each of one of array of light sensors and providing an output signal indicative of a change of state of the outputs of the array of sensors.

Title: Combined catalytic converter and afterburner
Inventor: MA THOMAS TSOI-HEI
IPC: F01N3/28
Filed: 1993-05-29
Abstract: A combined catalytic converter and afterburner comprises an afterburner chamber 16 and a catalyst matrix 11 disposed in series with one another in a casing 10. The afterburner chamber 16 has an ignition source 18 and it serves, in use, to receive a combustible premixed charge, the charge being ignited by the ignition source to cause it to burn before entering the catalyst matrix 11. Interruptions such as rings 42, 44 are provided on the inner surface of the wall of the afterburner chamber 16 in the path of the gas flow. These disturb the boundary layer of the premixed charge adjacent the wall, thereby ensuring that gases in the boundary layer are diverted away from the wall into the path of the flame propagating in the afterburner chamber 16 from the ignition source 18 and are burnt before reaching the catalyst matrix 11. <IMAGE>

Title: Control of pulse arc welding.
Inventor: TABATA YOICHIRO
IPC: B23K9/095
Filed: 1993-07-09
Abstract: Pulse welding apparatus has a pulse current waveform control circuit 8, which ensures that a desired current is supplied to a welding load unit 5, and is constructed such that optimum welding operation is performed without having to adjust circuit components or modify circuit design. The apparatus prevents defective welding due to magnetic blow and undercut and spatter resulting from external disturbances. The control circuit 8 is a microcomputerized digital circuit 100 which operates under a program to provide desired pulse arc current. Optimum welding current waveform parameters are learned in a first welding stage and stored into a memory 85. Arc length feedback control and current waveform control are performed under program control on the basis of the optimum welding current waveform parameters and target arc length signal 86 so as to control the faulty separation of globules when magnetic blow occurs. Short-circuit and separation detectors 82, 83 may also be included. <IMAGE>

Title: Thread formation
Inventor: CARTER NIGEL
IPC: B21J5/08
Filed: 1994-02-16
Abstract: The invention relates to thread formation and particularly to the formation of threads on deformed steel reinforcing rods. The method of forming a thread on the steel reinforcing rod comprises the steps of cold upsetting an end region (1) of a deformed steel reinforcing rod having a nominal diameter, the upsetting being arranged to increase the diameter of the end region to a new, upset, diameter greater than the nominal diameter, rolling a thread onto the end region (1) so as to produce a threaded region having a thread major diameter which is greater than the nominal diameter and a thread minor diameter which is less than the nominal diameter. The formation of such a thread enables the production of mechanical connections between pairs of rods, the connections having a strength greater than that of the rods being connected to one another. <IMAGE>

IPC: A23K20/174
Abstract: 941,359. Vitamin preparations. K. ABILDGAARD, [trading as LOVENS KEMISKE FABRIK VED A. KONGSTED]. Oct. 17, 1960 [Oct. 21, 1959], No. 35731/59. Heading A5B] A dry vitamin preparation containing one or more fat-soluble vitamins in the form of beadlets consists of droplets of a solution of one or more fat-soluble vitamins dissolved in an edible hydrophobic solvent such as a vegetable or animal fat or oil, and enclosed in a water-soluble, homogeneous, edible, solid protective matrix, the homogeneous phase further containing paminophenol and/or a salt thereof in an amount exceeding that sufficient to saturate the hydrophobic vitamin containing phase with the paminophenol and/or the salt thereof. The paminophenol and/or salt thereof may be present in the homogeneous phase as distinct solid particles. The vitamin preparation is produced by dispersing the solution of fat-soluble vitamins in an aqueous solution of the said homogeneous phase, adding the p-aminophenol and/or salt thereof either before or during the dispersion process and thereafter drying the resultant dispersion e.g. by spray drying. Alternatively, the homogeneous phase contains a gellable material and is dispersed in an oil to form drops, cooled and the resultant globular particles are filtered off, washed with a suitable solvent and dried. Suitable gelling materials are gelatin, blood albumin, glue, lactalbumin, carboxymethyl cellulose, methyl cellulose, pectin and starch. The homogeneous phase may contain one or more carbohydrates, e.g. glucose and lactose. The fat soluble vitamins may be Vitamins A, D, E or K and may be in the form of Vitamin A palmitate or Vitamin A ascorbate. The Provisional Specification refers to Specification 791,180.

Title: Object recognition process
Inventor: VEROVENKO OLGA OLEGOVNA
IPC: G09B19/06
Filed: 1994-06-30
Abstract: The invention relates to information technology, in particular to object recognition, and can be used to construct recognition systems based on modern computers, for modelling recognition processes which use modern computers, and also for training text editors and in language teaching. In the proposed object recognition process, a system of attributes is created corresponding to the object to be recognized, the recognition system reads the data file submitted for processing, the attributes corresponding to the objects contained in the data file are identified and compared with the created systems of attributes, and the objects possessing the created attribute systems are identified. The novelty of the invention lies in the fact that the creation of a system of attributes corresponding to each object to be recognized is done by reading in sequence the samples from a first group of samples, each of which contains models of the object to be recognized, the attributes corresponding to the object to be recognized are identified, the attributes identified in each model of the object to be recognized are compared among themselves, the samples being arranged in order of ascending complexity of the model of the object to be recognized included within them; after each sample from the first group has been processed, the sample from the second (control) sample group containing models of the same object to be recognized is read on the basis of the established characterizing attributes.

Title: Seat belt winding device with emergency clamping
Inventor: OHSUMI SADANORI
IPC: B60R22/34
Filed: 1995-04-13
Abstract: A seat belt winding device 12 with a clamping mechanism 27 for directly holding the seat belt webbing 13 in an emergency uses plastic deformation of both a clamp supporting device 29 and a webbing holding device 14 to absorb a larger amount of kinetic energy. When the clamping mechanism releases the webbing the diameter of a plastically deforming member portion of a bobbin 14 can be reduced greatly since the plastically deforming members 21 project in the radial direction of the bobbin. In alternative bobbins (Figs. 21 to 24), the deforming direction of the plastically deforming members due to the tightening of the webbing can be predetermined by inclining the end surfaces (727, 728, 827, 828) of the plastically deforming members in a specific direction. This allows the substantial winding diameter of the bobbin to be reduced uniformly and positively. Alternative designs for the deformation elements associated with the clamping mechanism are also disclosed (Figs. 4 to 14). <IMAGE>
