Title: Control circuit for insulated-gate bipolar transistor - includes opto-coupler with forward and reverse bias voltages and two time constants giving different control voltages at gate
Inventor: MATSUMOTO YOSHIHIRO
IPC: H03K17/04
Filed: 1993-05-07
Abstract: A first resistance (R1) and a Zener diode (ZD1) in series are connected across a second resistance (R2) between the positive terminal of a forward bias voltage source (Ef) and the collector of one transistor (Tc1) of the opto-coupler (2). The second resistance is the greater so that in combination with the gate-to-emitter capacitance of the UGBT (1) it defines a longer time constant. While the transistor (Tc1) conducts the IGBT is controlled by the greater of the two voltages. ADVANTAGE - Reduces rate of variation of collector-emitter voltage during switching-off, and minimises collector power loss during switching and stationary operation.

Title: Method and device for measuring <12>C and <13>C proportions
Inventor: FABINSKI WALTER DIPL ING
IPC: G01N21/3504
Filed: 1993-05-10
Abstract: The invention relates to a method and a device for measuring bound <12>C and <13>C proportions in liquid and/or solid media. In order to make it possible greatly to simplify the measurement of such <13>C proportions spectrometrically while retaining a high detection sensitivity, it is proposed according to the invention for the media intended for measurement to be, in a combined procedure, first oxidised in a thermal process with production of the components <12>CO2 and <13>CO2 and for both components to be fed directly into a non-dispersive infrared spectrometer for selective detection of the proportion of <12>CO2 and of <13>CO2. <IMAGE>

Title: Method and device for grinding the circular edge (rim) of a ceramic or porcelain article
Inventor: SPER GEROLD
IPC: B24B9/06
Filed: 1993-07-16
Abstract: A method and a device (10) for grinding the circular edge (12) of a ceramic or porcelain article (14) are described, the said article being held by a holding device (18) and driven rotationally about its median axis (76). The edge (12) of the article (14) is ground by means of a grinding tool (22) bearing on it and rotating relative to it. According to the invention, a rotationally symmetrical grinding tool (22) having a spherically or conically shaped grinding shoulder (32) is employed, the article (14) being arranged with its edge (12) firstly in the immediate vicinity of the grinding shoulder (32). Thereafter, the grinding tool (22) is displaced laterally towards the article (14) perpendicularly to the axis of rotation (76) until the edge (12) bears on the grinding shoulder (32). Following this, the grinding tool (22) is displaced axially and simultaneously laterally radially in such a way that the edge (12) to be ground moves along the grinding shoulder (32). <IMAGE>

Title: Treatment pen for cattle and other hooved animals
Inventor: SCHWARZ GUENTHER
IPC: A01L13/00
Filed: 1993-09-25
Abstract: The drawing shows a standard treatment pen for cattle and other hooved animals, having a holding structure (1) on which there are aligning and holding devices (grinding belts (13), hangers (16)) which are adjustable in such a way that the animal to be treated can be aligned in or on the holding structure (1) at a different height and position and can be immobilised. Furthermore, the holding structure (1) has a movable basic frame (2) with a standing surface (11) which is adjustable at least in height in such a way that at least the hoof care of the animal during treatment can be carried out at an unchanged height above the standing or bottom surface (11) of the holding structure (1). For this purpose, a plurality of upright supporting pillars (3, 4) are mounted on the basic frame (2), which have at a variable height aligning and holding means (grinding belts (13), hangers (16)) for aligning and holding the animal in the intended treatment position. In this way, it is achieved compared with the known hoof pens that the hoof treater does not have to bend down during his work and the animal does not have to assume an unnatural posture compared with conventional tilting pens. <IMAGE>

Title: Process for treating communal plastic waste
Inventor: LINKE ADOLF
IPC: C10J3/46
Filed: 1993-10-27
Abstract: In this process, the plastic waste, after being freed from metal parts, precleaned and comminuted, is compacted and heated in a screw extruder with elimination of HCl. The heating is continued until substantial removal of HCl has taken place and the viscosity of the plastic melt has dropped to < 300 cSt. The plastic melt is subsequently reacted in a flame reaction with a supply of oxygen in a gasification reactor. The resultant gas is cooled, dedusted and desulphurised. After the gas treatment, this gas can be utilised as synthesis gas in the chemical industry or for the recovery of energy in the generation of power or district heating.

Abstract: A baseplate for goods decoration surfaces, in particular display windows, display cases, goods layouts and the like, has two printed circuit boards (2, 3) which are located one above the other spaced apart and are connected to the two terminals of an electrical power source. The two printed circuit boards (2, 3) are provided with a mutually corresponding grid of insertion openings (9). A jack plug (13) can be inserted in each case in two insertion openings (9) which are located one above the other, so that each of the two plug terminals of said jack plug (13) touches in each case one of the two printed circuit boards (2, 3). In consequence, an electrical power supply for a component which can be arranged there can be obtained at any desired grid point on the baseplate, said component being, for example, a light or a goods mounting which can be driven electrically. <IMAGE>

Inventor: SPRINGER JOHANNES
IPC: B65H45/18
Filed: 1994-01-27
Abstract: The speed of the folding rollers 1 is to be optimally matched to the printed product 7 to be folded. This is achieved by providing motor 4 driving the folding rollers 1 in a manner decoupled from the main drive of the printing press and that of the folder. Product length and gaps between adjacent products are derived from scanner 8. Scanner 9 operates on the lateral edge of the product. Outputs from the scanners are used to calculate motor speed, which is kept to the minimum consistent with the folding of a product being completed before the next arrives at the rollers. Printing and product parameters may be input at 11. <IMAGE>

Patent DE-4428132-A1 (DE)
Inventor: KAETKER STEFAN
IPC: H04L12/26
Filed: 1994-08-06
Abstract: Described is a system with which a data-transmission network can be tested. The network consists of a number of nodes (A to I) which are connected to each other. At least one of the nodes (E) is designated to a user as being inaccessible from a first node (A). Within the network, data are available which, from the first node (A), indicate the way to the node (E) designated as inaccessible. An interrogation is carried out to determine which is the nearest node on the way from the first node (A) to the node designated as inaccessible (E). This nearest node (B) is then tested to determine whether it is accessible. If it is, an interrogation is carried out to determine this time which is the nearest node on the way from the node already reached (B) to the node designated as inaccessible (E). Again, this node (C) is tested to determine whether it is accessible. This process of interrogation and testing is repeated until the nearest node interrogated turns out to be inaccessible. This inaccessible node is considered to be defective and this fact is communicated to the user. The invention thus provides a test system which rapidly and automatically detects a defective node in a data-transmission network and indicates it to the user.
