Title: Insert for forming rectangular openings in concrete structures - is made from metal strip with elements to adjust size of rectangle
IPC: B28B7/34
Filed: 1991-01-17
Abstract: Rectangular openings in concrete structures are formed with the aid of an insert made from metal strip. A strip of the required length is cut from a roll of strip of the required width. The piece of strip is then folded to form a rectangle. The strip has longitudinal and transverse lines of weakness (14,15) which enable the metal to be folded to form V-shaped ribs which result in a reduction of the length and width of the rectangle. A single strip can thus be adapted to form rectangles of different sizes, resulting in a reduction of the number of different inserts required with a corresp. reduction in cost. USE/ADVANTAGE - Reducing the cost of forming rectangular openings in concrete structures.

Title: Device for pouring liq. contents from a tiltable vessel - has spout with closed front end and passage in sidewall to prevent cascade formation
Inventor: SCHEYKA PETER
IPC: C21C5/52
Filed: 1991-02-04
Abstract: Device for pouring liq. contents from a vessel (1) - which is tiltable about the axis (25) coinciding with the centre lines of the tilting bearings (21,23) - consists of a spout (2) with a closed front end(s). There is a passage (7) close to the end (5) in the side wall, and this passage is aligned with a passage (16) in the side wall of the trough (13) located beside the spout (2), with means provided for sealing the contact between the passages (7,16). These passages are located between the bearings (21, 23), with their centre line coinciding with the axis (25). The passage (7) goes through a refractory lining (4) and the main frame (6) of the spout (2). Mating flange units (8,11) provided with central bores are used to connect the passages (7,16). Spring force is used to press the flange units against one another. This is achieved by means of a spring (18) set with a given force against the spout side wall opposite to the wall incorporating the passage (7). USE/ADVANTAGE - Used in e.g. metallurgical industry. Liq. (including molten metals and alloys) can be poured from a container without forming a cascade, and thus avoids the additional oxygen contamination, which is particularly important in the case of easily oxidisable substances.

Title: Protection or HF generator feeding plasma generating consumer - has control circuit activating HF generator for reception of detector circuit output signal
Inventor: HANSEN ULRICH DIPL ING
IPC: H03L5/02
Filed: 1991-07-09
Abstract: The protection against destruction by defective power matching has a detector circuit (40) for fault matching of the HP generator (10) output to the input requirement of the consumer appliance (28). The detector circuit generates an output signal, indicating a fault matching. To the detector circuit is coupled a control circuit (46) for the rated output power of the HF generator in a fault matching instance. The control circuit acts on the HF generator such that it responds to the detector circuit output signal so that the output power of the HF generator is reduced until the power matching is attained, without reducing the required peak power required for the consumer appliance feed. USE/ADVANTAGE - For plasma generating consumer appliances, can for supply appliance with full peak output and protection despite faulty power matching.

Title: Electronic control for servo driven rollers of freight loading system - uses load sensing circuits to monitor roller action and interlocked control to move loads along programmed track
Inventor: HUBER THOMAS
IPC: B64D9/00
Filed: 1992-01-16
Abstract: The sets of servo driven rollers (A, B, C) are linked to a central processing control which monitors the loading on the separate servo motors. This provides information on the position of the loads. The monitoring circuits determine when the load has reached the end of each track and switches off the drive before the motors are damaged through overloading. The rollers are positioned in different tracks to move the loads along set paths, e.g. into the cargo hold of an aircraft. The rollers not in use are retracted out of contact with the loads. A simple interconnection control prevents more than one set of rollers operating at a time. USE/ADVANTAGE - For loading aircraft. Increased working life of rollers, improved reliability.

Patent DE-4330381-A1 (DE)
Inventor: BAIATU TUDOR DR
IPC: H02H7/12
Filed: 1993-09-08
Abstract: In the case of electrical converters (1, 8) having a DC intermediate circuit (2), very high short-circuit currents occur in the DC intermediate circuit (2) and in the phase modules of the electrical converter (1, 8) affected, as a result of the low-impedance discharge in the event of the short-circuit of an intermediate-circuit capacitor (C1, C2, C3), unless a short-circuit current limiter (3) is used, which short-circuit currents result in high forces being applied to the structural parts and possibly lead to arcs in the electrical converter (1, 8). In order to avoid this, a reversible short-circuit current limiter (3) which has a PTC thermistor (5) is connected in a low-inductance and cooled manner in series with at least one capacitor (C2, C3) or in series with a capacitor bank of the DC intermediate circuit (2). The PTC thermistor (5) can be arranged in the DC intermediate circuit (2) or in the electrical converter (1, 8). A varistor (6) and/or a non-reactive resistor (7) and/or a diode (4), connected in the reverse direction of a short-circuit path, can be connected in parallel with the PTC thermistor (5), the PTC thermistor (5) and the varistor (6), or the PTC thermistor (5) and the non-reactive resistor (7) being capable of being combined to form one component. <IMAGE>

Title: Device for measuring moisture content in a particulate mass
IPC: G01N25/56
Filed: 1993-09-13
Abstract: The invention relates to a device, in which an instrument to be embedded in the particulate mass 1 has two potential poles 4, starting from which in the event of a potential difference balancing is performed via the particulate mass 1 as a function of the respective moisture content, and in which the potential-pole instrument is connected to an electrical power source 9 and a measuring instrument 15, 16 for an electrical quantity, and a clock instrument 11 is provided. In this case, it is desired for the device to be independent of process water to be refilled and for the dependence of the balancing starting from the potential poles on the respective added chemical content of the particulate mass to be reduced. This is achieved in that the instrument 4 having the two potential poles 4 is a differential-temperature Peltier element 3 which is connected to the electrical power source 9 for loading a temperature difference across the two temperature potential poles 4, and balancing of the temperature difference via the particulate mass over a period of time defined by the clock instrument 11 can be established by a connectable voltmeter 14, 15. In the case of the device, the two physical characteristics exhibited by the differential-temperature Peltier element are exploited. <IMAGE>

Title: Process for producing refractory products based on magnesium oxide
Inventor: TUAN ANH VU DIPL ING
IPC: C04B35/043
Filed: 1993-09-18
Abstract: The invention relates to a process for producing refractory products based on magnesium oxide. In the process, coarse aluminium hydroxide-containing grains having a particle size of at least 0.5 mm are used and added to the mixtures of the magnesium oxide grains. The coarse aluminium hydroxide-containing grains are to be obtained by a granulation process from fine aluminium hydroxides with or without aluminium oxide. These hydroxide grains can be used in the untreated state or after pretreatment at a temperature of up to 1700 DEG C. The shaped bodies manufactured by the proposed process have a higher mechanical strength and better thermal shock resistance (TSR) than those produced by just mixing a pulverulent Al(OH)3 into the magnesium oxide grains.
