Abstract: A sheet discriminating apparatus includes a light emitter (8a) for emitting light onto a sheet being transported, a light receiver for detecting an amount of light transmitted through the sheet and a sheet discriminator for discriminating a specified kind of the sheet from others and/or abnormal feed of sheets based upon the amount of light transmitted through the sheet detected by the light receiver. The sheet discriminator includes an average value calculator for calculating an average value of the amount of light transmitted through the sheet detected by the light receiver at a predetermined time interval; a reference data calculator for calculating and storing a reference data based upon the average value of the amount of light transmitted through a sheet preceding the sheet to be discriminated and stored in the average value calculator, and an average data comparator for comparing the average value of the amount of light transmitted through the sheet calculated in the average value calculator with the reference data calculated by the reference data calculator and discriminating the specified kind of sheet from others and/or abnormal feed. The thus constituted apparatus can discriminate whether or not sheets are of a specified kind and/or whether or not abnormal feed of sheets such as double feed occurs for various kind of sheets. <IMAGE>

Title: Spacing dielectric on inner electrode from outer electrode - in tubular ozoniser by springy metal tongues to maintain constant flow channel
Inventor: FISCHER MELCHIOR DR
IPC: C01B13/11
Filed: 1990-05-03
Abstract: Corona discharge produces ozone from oxygen or air flowing in the elongated annular gap (5) between an outer tubular metal electrode (1) and a concentric inner electrode (2). The gap includes a concentric layer (3,4) of dielectric, e.g. enamel, to separate the electrodes. Peripherally and along their axial length the two electrodes are spaced from each other by regularly distributed springy metal tongues (5,8) where shape, size, arrangement and number combine to balance the weight of the inner electrode. The tongues may be  projections, all pointing in the same direction, from an elongated metal strip (7) or from annular supports; tongues may be integrally stamped from the strip or spot-welded. ADVANTAGE - Uniformly dimensioned discharge gap is maintained even after long surface, while small metallic contacts do not seriously affect ozoniser output.

Title: Heat to mechanical energy conversion engine - uses heat, to heat working gas in working cylinder chamber, without gas being combusted
Inventor: KOLB HORST
IPC: F02B33/20
Filed: 1991-10-17
Abstract: The heat energy is used to heat a working gas, which is at a to a preset operational temperature in a chamber. Expansion reduces the gas to a lower relief pressure, and this drives a piston, which is located in a working chamber, the internal chamber of a working cylinder. The working gas is introduced at a pressure, corresponding to the operational pressure, into the chamber, which is already at operational temperature, by short opening and closing of an intake valve (14). This is at a volume, corresponding to the contents of the working chamber. ADVANTAGE - Increased work output from engine.
