Abstract: Spent kieselguhr used as a filter medium, preferably in breweries, is regenerated by adding 2 to 8% sodium hydroxide solution at a reaction temperature of about 60 to 90 DEG C and subjecting it to gentle stirring for a reaction time from 30 to 120 minutes. The concentration of the sodium hydroxide solution is then 4 to 5% and the reaction temperature 80 to 90 DEG C. The spent kieselguhr is discharged into a heatable vessel. After the end of the reaction time, the sodium hydroxide solution is removed and the kieselguhr is washed clear by means of a vacuum filter or pressurised belt filter in a plurality of extraction stages. For complete removal of the alkali, sulphuric acid or hydrochloric acid in a concentration of up to 0.1% is added to the washing water in the last extraction stage.

Title: Four-transistor (4t) static ram cells
IPC: G11C11/412
Filed: 1987-12-10
Granted: 1992-04-22
Abstract: A 4T static RAM cell (10) comprising a flip-flop with two pull-down transistors (18, 20) and two pass-gate transistors (12, 14) is fabricated employing two separate gate oxide formations (74, 76) and associated separate polysilicon depositions (52a-b, 56). Two reduced area butting contacts (58, 60) connect to the nodes (26, 30) of the circuit (10). The reduced area butting contacts comprise vertically-disposed, doped polysilicon plugs (94), which intersect and electrically interconnect buried polysilicon layers (load poly 88, gate poly 52a) with doped silicon regions (80) in a bottom layer.   Adding the processing steps of forming separate gate oxides for the pull-down and pass-gate transistors results in a smaller cell area and reduces the requirements of the butting contacts from three to two. Further, the separate gate oxidations permit independent optimization of the pull-down and pass-gate transistors.

Abstract: The installation comprises a combination of a loop with great inertia and moderate temperature (7) and a loop with low inertia and a higher temperature (10). When there is a demand for calories on the part of the means of regulating the temperature of the loop (10), the former controls a relay which switches a switching valve (4) positioned at the point where the water leaves the boiler (1) towards the second loop (10) and also sets the burner control of the boiler to the aquastat (3) of the latter, the set temperature of which is high. When there is no longer a demand for calories on the part of the loop (10), said relay switches the valve (7) towards the loop (7) and the burner control to a second aquastat (8) at the beginning of the loop (7) and to the means of regulating the temperature of the loop (7). For example, the first loop (7) can feed floor heating (PC1 to PC3) provided in the daytime part of a house and the second loop (10) radiators of low inertia and low water capacity (R1 to R3) located in the night-time part. <IMAGE>

Abstract: A method and an apparatus by means of which the worn surface of the lining (3) of a steel ladle (1) can be removed while remaining true to the original contour, in a uniform layer thickness. Tools (30) on flexible displaceable arms (27) are pressed against the inner circumference (4) of the lining.

Abstract: PCT No. PCT/AU88/00419 Sec. 371 Date Jun. 14, 1990 Sec. 102(e) Date Jun. 14, 1990 PCT Filed Oct. 28, 1988 PCT Pub. No. WO89/04082 PCT Pub. Date May 5, 1989.A high efficiency power conversion at high frequencies with zero voltage switching is obtained by using magnetizing current of a transformer or parallel inductance to charge the switch adjunct capacitance and other capacitance during the dead time. A transformer is prevented from being loaded during the dead time. Loading of the transformer during the dead time is prevented by directing the output inertial current to a capacitor instead of through the rectifiers to the secondary of the transformer. This can also be achieved by using synchronized rectification that provides pulse width modulated regulation on the output and ensures that the transformer secondary is separated from the inertial current of the output during the dead time. Voltage and current stresses on the switching devices and rectifiers are minimized. Zero voltage switching may be applied to inverters where the load is resistive.

Title: Cleaning process
IPC: C11D7/12
Filed: 1989-01-24
Granted: 1992-06-24
Abstract: The invention allows cleaning of poorly accessible machine parts, e.g. in the transport and or moulding of materials in the pasty state by addition of one ore more inorganic or organic solvent(s) and one or more inorganic or organic salt(s) which are soluble therein, preferably as a solution, to the material to be processed. The melting point of the salt(s) is above the processing temperature of the material. The boiling point of the solvent(s) is below the processing temperature of tie material. The invention finds its application in the changeover of material to be processed in plastic processing machines, such as, injection moulding machines, extruders and blow-moulding equipment by accelerating the removal of the previous substance from the plasticizer unit and the nozzle region; an analogous field of use is, e.g. in the operation of kneaders.

Abstract: When different codes are used for the compression depending on the type of data to be compressed in each case, the choice of the most advantageous code in each case is controlled by flags individually allocated to the data characters, which specify the type of data (DAx) in each case supplying the most advantageous compression results. For each data character to be compressed, this flag is first determined and it is then checked whether the type of data forming the basis for the current compression still corresponds to that corresponding to the flag. If there is a deviation, the system changes to the new type of data, the change suitably occurring as a function of several deviating flags of successive data characters and being initiated by a control character identifying the new type of data. <IMAGE>
