Patent DE-4242382-A1 (DE)
Inventor: BERG JOACHIM
IPC: F23N5/24
Filed: 1992-12-08
Abstract: Heating device with a burner acting upon a heat exchanger and a waste gas pipe made of a combustible or only limitedly temperature-resistant material, in the connection region of which to a combustion chamber receiving the burner a safety temperature limiter is arranged, which, when a given temperature is exceeded, emits a signal which influences the fuel supply of the burner. In order, in the case of such a burner, to avoid a predetermined temperature of the waste gas being exceeded, it is envisaged that the safety temperature limiter is formed by a temperature sensor (13), which is arranged in the waste gas line (10), and an evaluating circuit (14) which processes the signals of the sensor and which comprises a threshold switch, which causes the burner (2) to be switched off when the threshold is exceeded, and a control circuit which, when a predetermined threshold is approached, emits a signal which influences the output adjustment of the burner (2) with the effect of a reduction thereof. <IMAGE>

Title: Arithmetic logic unit with accumulator function - has two memories and counter with selection to reduce delay in processing
Inventor: URAMOTO SHINICHI
IPC: G06F7/507
Filed: 1993-02-02
Abstract: The arithmetic logic unit with an accumulator function has an incrementing mode counter (3), a selector (9), a pair of memories (2a,b) and an adder circuit (1). The memories operate on a synchronous cycle with the adder cycle and that of the counter. The selector can be in the form of a multiplexer that is controlled by the carry signal from the adder. When there is not a carry generated by the adder the adder output is entered into the second memory (2b) to provide a direct entry into the counter. ADVANTAGE - Reduces processing delay for faster operation.

Title: Method for volume flow control of gear pumps, and gear pump for implementing the method
Inventor: EHLEN SIEGFRIED
IPC: F04C14/18
Filed: 1993-02-06
Abstract: The invention relates to a method for volume flow control of gear pumps and to gear pumps for implementing the method. One gearwheel out of each two gearwheels meshing with one another is displaced (translated), in a positioning chamber, parallel to the other gearwheel in such a way that as a result of the extent of the meshing (tooth contact) being varied, the output flow rate is adjusted towards the setpoint of the volume flow. To prevent a void from forming in the process, a filler piece is made to follow.
Patent DE-4305964-A1 (DE)
Title: Process for the multi-stage thermal treatment of composite material for the purpose of utilisation of materials and energy with low emission and low residues (recycling)
Inventor: JESCHAR RUDOLF PROF DR ING DR
IPC: C01B7/01
Filed: 1993-02-26
Abstract: The process according to the invention serves for separation of the material components of a composite material in thermal processes. In this case, the organic material fractions are decomposed thermally and utilised for their energy as process gas in an incineration device operated in parallel, preferably for supplying process heat to the multi-chamber continuous reactor used for carrying out the process. The gas generation, fractionated with respect to temperature and reaction space, permits optimised purification of the pollutant-containing process gases generated in definable process stages and thus makes a contribution to low-emission operation. The oxidation (gasification) of the carbon, which is contained in the composite material or has been separated off in the thermal decomposition process, reduces the quantity of residues obtained to inert, predominantly mineral materials. The inorganic fraction, which can be used as a secondary raw material and is predominantly present as metal, of the composite material is largely reduced to metallic materials and is therefore re-usable at high effectiveness.

Title: Air coupled current transformer
Inventor: GOODWIN WENDEL R
IPC: H01F38/30
Filed: 1994-01-10
Abstract: The device transforms an input current flowing in an input lead to an output signal. A primary current loop device supplies the input current. A first secondary current loop device is arranged adjoining the primary device to induce a first electromotive force (EMF) in dependence on the input current and a second EMF in dependence on an external magnetic flux disturbance. A second secondary current device adjoining the primary device induces a third EMF in dependence on the input current and a fourth EMF in dependence on the magnetic flux.The secondary current devices are coupled such that the output signal corresponds to the sum of the first and second EMFs and the difference between the second and fourth EMFs. A magnetic coupler obtains a coupling magnetic flux between the primary device and the first and second secondary devices to minimise the difference between the second and fourth EMFs. The magnetic coupler includes at least two air gaps.
