Title: Transverse magnetic recording material mfr. - uses sputtering process to form film of Neodymium-Iron-Boron on surface of non magnetic carrier.
Inventor: SEGAWA MASARU
IPC: G11B5/64
Filed: 1992-11-13
Abstract: The transverse magnetic recording medium providing high density recording capacity is produced by forming a thin magnetic film on the surface of a non magnetic base. The magnetic film is produced with an alloy of Nd.Fe.B material contg. not more than 13 atom percent of Nd, and up to 4 atom percent of B, with the remainder being Fe. Other elements of Co,Ga,Si, and V may be included as additives. The formation of the magnetic film is carried out using a sputtering process with a gas pressure of 20-40 milli-Torr and a temp. of less than 100 degrees Celsius. ADVANTAGE - High magnetic density. Low internal voltage and free from worsening magnetic characteristics.

Title: Chip-carrying card mfr. - involves chip recess prodn. by forming blind hole and then embossing
Inventor: KETZER GEORG
IPC: G06K19/077
Filed: 1992-12-09
Abstract: In the mfr. of IC cards (e.g. cheque, credit, telephone and identify cards), involving fixing of an IC chip in a recess (M) formed in a plastics card, the novelty is that the recess (M) is formed by (i) producing a blind hole (S) in the card (K); and (ii) forming the recess (M) by means of an embossing punch (P), the excess plastics being displaced into the blind hole (S). Also claimed is the appts. used for carrying out the above process. ADVANTAGE - The process has a short prodn. time (e.g. 2.4 secs. per card compared with 6 secs. or more for prior art processes) and solves the problem of material displaced during the embossing operation.

Title: Device for the injection of a fuel-gas mixture
Inventor: BANTLEON GUENTHER DIPL ING
IPC: F02M51/08
Filed: 1993-02-17
Abstract: Devices for the injection of a fuel-gas mixture with a canister-shaped gas surround sleeve enclosing a valve end of a fuel injection valve are already known, in which the casing part of the gas surround sleeve bears on the valve end of the fuel injection valve and in which an annular gas gap is formed between an injection hole plate and the base part of the gas surround sleeve. The said gas surround sleeves have an expensive construction and high manufacturing and assembly costs. The new device has the advantage of a low-cost, easily assemblable and easily adjustable gas surround sleeve (1). The gas surround sleeve (1) rests with its casing part (8), for example, only on four rounded edges (84) of the square-shaped valve end (4), whilst the casing part (8) surrounds the surfaces (83) of the valve end (4) with a radial clearance, so that intermediate gas spaces (90) for the gas feed are formed between them. The proposed device for the injection of a fuel-gas mixture is particularly suitable for injection into the intake pipe of a mixture-compressing internal combustion engine with applied ignition.   <IMAGE>

Title: Pre-sieve for pressing-worm separators for separating and dewatering solids from liquids
Inventor: EICHLER DIETRICH DR
IPC: C02F11/125
Filed: 1993-04-16
Abstract: The invention relates to increasing the throughput capacity of pressing-worm separators for separating solids from waste water and sludges occurring in industry and agriculture with simultaneously great mechanical dewatering of the solid to form a compostable or otherwise easy-to-handle product. The method and the device are used primarily for separation of suspensions with low dry proportions of under 2 per cent. The essential changes to the previously known machine relate to the arrangement of a pre-sieve. The increase in the throughput capacity is achieved by a vertical pre-sieve with a worm driven independently of the separator being arranged on the pressing-worm separator. In this case, a bar sieve which is constructionally identical to the pressing-worm separator in length and diameter is used in the device.

Title: Commercial assessment of carcasses by video camera
Inventor: EGER HORST DIPL ING
IPC: G06T7/521
Filed: 1994-03-08
Abstract: The meat is video-recorded on a background; the pictures are converted from the red, green and blue channels into corresp. 3D colour attributes, in order to differentiate fat, connective tissue, bones and background. The background colour attribute is set to blue. Multi dimensional histogram analysis differentiates colour, in order to identify the background, outline and contours. Mean and most frequent colour values are determined by selective planimetry, covering tissue components and background. Colour classification determines the outer contours and their characteristics, using the centroid-to-pixel vector length method, to determine whether the pixel belongs to fat, flesh, bone or background. A light-sectioning procedure adds depth information to the two-dimensional conformation determined.
Patent DE-4408754-A1 (DE)
Inventor: FOCKELE MATTHIAS
IPC: B29C67/00
Filed: 1994-03-15
Abstract: A stereolithographic process and device are disclosed for producing an object (8) in a bath of a radiation-hardenable dielectric liquid (4). The layer of the object (8) most recently hardened by radiation next to the surface (22) of the bath is moved forward in the bath in order to provide a liquid layer to be subsequently radiation-hardened on the previously hardened layer. In order to produce a subsequently hardened layer having a uniform thickness on the previously hardened layer, an electric field is generated by high-voltage electrodes (28, 29) and/or an ultrasonic field is generated by ultrasonic sources and the field is made to act on the liquid that forms the layer to be subsequently hardened. Another aspect of the invention is that an electric field is made to act on the presently irradiated area while the liquid is hardened. This allows privileged directions of the liquid molecules to be set that are expressed in the hardened object (8) by anisotropies of its physical properties.

Abstract: Telecommunications infrastructure allowing a call addressed to a particular subscriber to be picked up at one of at least two separate terminals. The aim of the invention is to allow calls to be switched between the terminals in question. The basic concept is that the subscriber (10) is identified to at least one terminal (11) by a subscriber identification card which can be remotely interrogated within a circumscribed area. The subscriber (10) registers all his terminal devices (11, 12) (at home, in the office, in the car, portable) with a service operator (3); each terminal device which recognizes, through remote interrogation, that the subscriber is nearby reports this fact to the service operator (3). Calls addressed to the subscriber are directed to the service operator and whence to whichever terminal device reported last. The invention provides automatic switching without any restriction on the subscriber's freedom of movement.
