Title: Flow control for hot water heating system - reduces pump speed when faster temperature rise indicates flow valve is reduced or closed
Inventor: OEHLER HEINRICH DIPL ING
IPC: F24D19/10
Filed: 1991-06-07
Abstract: The hot water heating system has a main tank (1) which is heated, and a pumped supply to a heat exchanger (4), from which a cool return closes the recirculation loop. The flow control valve (5) regulates the flowrate through the heat exchanger, while a thermostat regulates the heating of the main tank. The control system monitors the rate of rise of temperature in the main tank and varies the pump speed accordingly, to prevent high pump speeds generating valve noise for low flowrates. If the rate of temperature rise is steep, indicative of low flowrates, then the pump speed is reduced accordingly. Slow temperature rises indicate larger flowrates, requiring more pump output. ADVANTAGE - Reduced valve noise, optimised pump speeds.

Title: Casting molten metal from elongated metallurgical container - involves virtual sepn. of part of metal close to tapping hole from rest of container
Inventor: BIGLARI KAIWAN
IPC: C21C7/00
Filed: 1992-06-09
Abstract: The method for casting molten metal from a flat elongated metallurgical container provided with a tapping hole near one of its ends is based on virtual separation of a part of the metal close to the tapping hole (3) from the rest in the container. The wire injection method is used to add a calculated amount of a treatment material to this separated part, where it is evenly distributed by an external measure before the melt is poured off through the tapping hole. Virtual separation of a part of molten metal is achieved by means of a barrier (20) made of a refractory material, while a stirring effect, to distribute the added material, is produced by means of gas applied through a distributer element (30). USE/ADVANTAGE - The invention can be used in the metallurgical industry. It allows treatment materials to be uniformly distributed in the melt before the pouring-off operation, and enables thus castings of more consistent quality to be produced.

Patent DE-4239382-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: F02M25/08
Filed: 1992-11-24
Abstract: In a process and device for preventing incorrect signals in the diagnosis of a tank aeration valve, a check is made to see whether an operating characteristic of the internal combustion engine which is relevant to the diagnosis changes at the same time as a prior art diagnostic procedure is being conducted. If such a change occurs during the diagnosis or if the absolute value of the characteristic of the extent of the change exceeds a predetermined threshold value, the evalutation of the diagnostic process is suppressed so that possibly unreliable diagnosis results are prevented.

Patent DE-4303979-A1 (DE)
Title: Car radio with antenna diversity
Inventor: BIERE DIETMAR
IPC: H04B1/10
Filed: 1993-02-11
Abstract: In known diversity systems for mobile broadcast reception, in which the antenna signal processed in the IF section of the receiver is used for detecting interference in the diversity processor, a separate additional IF demodulator is required for the diversity circuit. Further disadvantages result from the more or less high expenditure of components, housings and RF lines and from losses and noise sources also associated therewith, depending on the arrangement of the individual components in the vehicle - antennas, amplifiers, diversity and receiver. According to the invention, the tuner (4) is spatially detached from the receiver and directly connected to the antenna outputs or moved into their vicinity. At the same time, the diversity circuit (2.2, 2.3) is integrated in the tuner. As a result, the demodulated IF signal of the tuner IF section (3.2, 3.3) can be connected directly to the diversity processor (2.2). No separate IF demodulator is required for the diversity circuit. Like the diversity elements, the amplifier sections (1.2) of the active antennas can also be integrated in the tuner model according to the invention. The advantages of the invention in the form of considerable reduction in components and cost have an optimum effect in a multi-antenna window in which the outputs of the passive antenna structures (1.1) are combined at one point and the tuner model (4) with integrated amplifier diversity circuit is [lacuna] in a member directly next to the window ...
