Title: Recognition of characters stored in matrix format - using position binary vector conversion, weighting, comparison and tabular addressing
Inventor: HANISCH WILFRIED
IPC: G06V10/40
Filed: 1978-01-07
Abstract: Recognition method is for characters stored in matrix format and enables high operating speeds by use of sequential processing without repetitive scanning. A series of characteristic codes is converted into a binary vector according to position. The vectore are classified according to value sums. This enables elimination of a number of identity groups, after which the characteristic codes are analysed and weighted. The weighted values are summed and the class identified when the next class threshold is not attained. The difference value then identifies the character in the identified group.

Title: Overload protection circuit for transistor switch - has extra transistor preventing voltage spikes from protective thyristor from adversely affecting switch
Inventor: JAJE WALTER ING
IPC: H03K17/082
Filed: 1978-05-05
Abstract: The overload protection circuit, for a transistor switch, employs a thyristor to protect the switch. The transistor is unaffected by unwanted voltage spikes originating from the thyristor. An auxiliary transistor (T2) is connected in series with the protection thyristor (Th) and conducts only when the thyristor is conducting. The thyristor is shunted by a capacitor (C2) which may be in series with a protective resistor (R4). The auxiliary transistor's base may be connected to its own potential source (U') at the same time as the switching transistor's base is connected to its own source, i.e. ground. The circuit may be used in telephone exchanges where signals currents from low impedance current sources are connected to lines via transistor switches.

Title: Fire-resistant casing for industrial fittings and machinery - is quilted, insulated, resilient envelope that expands selectively when exposed to naked flame
Inventor: PETERSON ROGER LEE
IPC: H02K5/22
Filed: 1978-07-14
Abstract: Industrial installations such as electric conductors, cables, tubes, fittings, electric motors, are protected against high-temp. naked flames e.g. from hydrocarbon fires, by a casing that can be opened on 1 side to allow installing of the article to be protected. The sides of the casing consist of >=1 layer of resilient, insulating and compressible material e.g. (in)organic fibres or foam or ceramic fibres. Each side of the casing has relatively numerous clamps or fasteners passing through it which compress the layer and comprise at least partly a material that is less resistant to high temp. than the insulating material of the casing sidewalls, the latter being encased in a textile envelope of nylon, polyester or glass-fibre-fleece fabric. Insulating layer, envelope and fasteners are adjusted w.r.t. one another so that when the device is subjected to a flame then the fasteners are destroyed, thus allowing the insulating layer of the sidewalls to expand and causing the 1 open side of the casing to close and overlap. In this way that side exposed to the fire to a max. extent assumes a greater insulating thickness than the other sides.

Title: Tumbler for transferring heat between different materials - comprises hollow inverted cone rotated to tumble materials, used esp. in hot briquetting of steel mill waste
Inventor: MOORE JAMES E
IPC: B01F29/60
Filed: 1978-08-09
Abstract: The tumbler has a lower portion in the form of a hollow inverted cone having an included angle of 80-135 degrees C. The lower portion has an axial outlet and is closed by a circular cover having an axial inlet. The tumbler is rotatably supported with its axis inclined at 30-75 degrees to the horizontal and is rotated at a speed ranging from a fraction of a revolution per min. up to several revolutions per min. The outlet is restricted to control the rate of flow so that a body of material is maintained in the tumbler and constantly mixed by cascading material introduced at the inlet across the surface of the body. Used esp. for transfer of heat between briquettes and the raw materials from which they are formed, esp. in plants for hot briquetting of steel mill waste. Allows good heat transfer between fine and coarse materials because the fine particles tend to flow continuously through the interstices between the larger particles as the tumbler rotates.
