Title: Disposal of waste with metal and metal vapour material - has receptacle with grid immersed in fluid and lower conveyor to carry out fragments and sludge
Inventor: KOEHLER ANTONIUS
IPC: B09B3/00
Filed: 1992-10-01
Abstract: The appts. for the disposal of metal waste, also matter contg. metal vapour, has a receptacle (1) with a grid (6) in a fluid to hold the material while it is broken into fragments. A conveyor (7) is below the grind (6) to carry off the mixture of broken glass and metal and the sludge formed, out from the side of the receptacle and upwards into a storage container. The conveyor (7) has a horizontal conveyor section (8) leading to a further section (9) at an upwards angle to carry material from the receptacle (1) to a container. The horizontal conveyor section (8) is a drag chain conveyor and the angled section (9) is a bucket conveyor. The conveyor (7) is located in a channel section at the base of the receptacle, leading upwards at one or both sides, leading to an external closed channel (10) containing the angled section (9), leading to a height level over the fluid level in the receptacle. The system is charged by an upper table, swinging upwards with an opening which is released and closed automatically on the swing movement, and is closed when the breaker is below the filling opening. A counter is at the table for the swing stroke. The breaker is a plate (4) moving up and down in the receptacle, or a swing unit with a number of parallel tined breaker arms. The conveyor can pass through a filter for floating matter. The receptacle can have a semi-circular cross-section with a vertical end wall, with the conveyor near the wall at its lowest point. USE/ADVANTAGE - For the disposal of waste with a hazardous content, such as mercury lamps, to convert the harmful matter into safe cpds. and esp. sulphide.

Title: Circuit for the CSD [canonical signed digit] encoding of a binary two's complement or binary number
Inventor: HERRFELD ANDREAS
IPC: H03M7/06
Filed: 1993-03-15
Abstract: Digital circuit for the CSD encoding of a binary two's complement number or binary number which has no sign, in which the properties of the CSD code mean that two neighbouring bit positions cannot be occupied at the same time. Since the CSD code can be generated only recursively, it was deemed important for there to be a minimum delay for each bit position. The basic circuit has a delay time of one NOR gate for each bit position. An additional look-ahead logic unit, which is connected in parallel with the basic logic unit, reduces the delay time many times over. A look-ahead logic unit of any desired bit length requires a delay time of 2 NAND gates from the relevant input to the output. In an exemplary embodiment using a look-ahead length of 8 bits, it was possible to generate a 32-bit word in 15.5 NAND-gate delays and a 64-bit CSD code word in 23.5 NAND-gate delays, both in the context of tenable hardware expenditure. <IMAGE>

Title: Method and circuit arrangement for controlling the temperature of a resistance heater
Inventor: JESCHKE HELMUT DIPL ING
IPC: G05D23/24
Filed: 1993-04-15
Abstract: The invention is based on the problem of creating a method and a circuit arrangement for controlling the temperature of a resistance heater, which manage with a DC-voltage source. Fluctuations in the ambient temperature and/or fluctuations in the supply voltage are furthermore to be compensated for as far as possible. The sensitivity of the sensor is likewise to be specifically influenced. According to the invention, the problem is solved by measuring a direct voltage across a non-reactive (ohmic) resistor, the value of which is known, and in addition the total voltage across this resistor and a series-connected heating resistor. By subsequently comparing, in an operational amplifier, a part of this total voltage with the voltage across the non-reactive resistor, whose value is known, the differential voltage resulting therefrom is amplified and subsequently assigned to an adjusting transistor. This transistor, in turn, controls the voltage across the heating resistor such that the electric resistance of the heating resistor and consequently also its temperature are constant. The invention relates to a method and a circuit arrangement for controlling the temperature of a resistance heater, for example for a gas sensor. <IMAGE>

Title: Drive arrangement for plough systems or face conveyors
Inventor: PAGO BERND-CHRISTIAN
IPC: E21C35/04
Filed: 1993-05-19
Abstract: The invention relates to a drive arrangement for face conveyors or plough systems, with drive units which each consist of an electric asynchronous motor (3) and overload-protection gearing (4) with allocated overload clutch in the configuration of a multiple-disc clutch (6), the gearing of the drive units being preferably designed as load-compensation gearing. According to the invention, by means of an electronic control device (9), running-up of the motor on no load when the multiple-disc clutch (6) is opened and subsequently a smooth start-up of the conveyor or the plough systems is effected by controlled or regulated control actuation of a solenoid valve (7) allocated to the multiple-disc clutch (6). In the process, pressure is slowly applied to the multiple-disc clutch in the start-up phase so that the force passed into the chain (1) slowly increases until the face conveyor or the plough system has started. <IMAGE>
