Patent EP-0012154-A1 (EP)
Inventor: SCHOLZ KLAUS
IPC: B23Q35/10
Filed: 1979-08-13
Abstract: The cutter head for the traced rough turning of rod-like workpieces includes a rotary base ring provided with a plurality of radial guideways. A supporting member in the form of a slide carriage movable on the radial guideways supports an elongated blade holder which is pivotable about a hinge point laterally offset from the guideways. The free end of each blade holder carries an inserted blade and is spring biased against the workpiece at the center of the base ring by a set of biasing springs supported on the slide carriage. A tracer pin adjoins the cutting blade and its vertical position is adjustable relative to the main cutting edge to determine the thickness of the cuttings. The point of contact of the cutting edge relative to the center of the hinge joint forms with a tangent line passing through the contact point an angle between 10 DEG  to 25 DEG .

Abstract: The invention relates to a water treatment system which includes a water treatment tank (20) containing a resin bed (22) through which water is passed for treatment thereof during normal operation of the treatment system. A brine tank (24) contains a brine solution (26) which, when passed through the resin bed, results in regeneration of the treatment effectiveness of the bed. A plurality of electrically actuatable valves (28,30) direct water through the treatment tank during normal operation of the treatment system and direct brine solution through the treatment tank in a regeneration operation. A control for the water treatment system includes switches (S1 to S5) for manually entering control data, a display (98) for displaying data, and a sensor (31) for sensing the volume of water treated by the water treatment system. A controller circuit (Figure 2) is responsive to the switches (51 to S5) and to the sensor (31) and is connected to display data on the display (98). The controller circuit provides electrical control signals to the plurality of electrically actuatable valves. The sequence, duration, and time of occurrence of the electrical control signals is determined by the control data entered through the switches.

Abstract: A temperature responsive fluid control valve (10) with sequential control functions, employing a pair of axially aligned hollow elongate plungers (22, 70) and a pair of ball valves each comprising a valve member (32, 90) and a valve seat (34, 92). One ball valve is straddled by the two plungers, being biased onto its seat by the second plunger and movable from its seat by the first plunger. This ball valve controls a first fluid path (42, 56) in response to a temperature sensitive element (18") acting on the first plunger. The second ball valve is operated sequentially after the first, via the second plunger for control of a second fluid path (78, 86) in response to the same temperature sensitive element. The valve is suitable for use in regulating the temperature of an engine by using the first fluid path to control a shutter (58) and the second fluid path to control a fan (88) to control together the flow of air past the engine radiator.

Abstract: Electrodeposition of a hard, bright, ductile gold alloy having a white coloration, useful for decorative purposes, is effected using an aqueous cyanide-free electroplating bath essentially comsprising:
     (a) from 4 to 20 g/I of gold,   (b) from 0.2 to 5.0 g/I of palladium,   (c) from 0.1 to 3.0 g/I of copper,   (d) from 5 to 200 g/l of free sulphite ion,   (e) from 0 to 150 g/l of one or more buffering agents and/or conducting salts, and   (f) water.     
The bath has a pH in the range from 7 to 10.5, preferably about 9.5 and electrodeposition of the white alloy can be carried out at a cathode current density of from 0.25to 1.25 amp/dm 2  and a temperature of 50 to 65°C., preferably with moderate agitation of the cathode during the electroplating process The white alloy will normally contain, on a parts by weight basis. 85-95 gold, 3-10 palladium and 2-5 copper, the palladium always being present in a larger amount than the copper.
     Such a bath is not as susceptible to colour stability problems as conventional cyanide-based electroplating baths for producing white gold electrodeposits.

Abstract: in a printer that uses a prithead (22') with multiple electrodes (56) for supplying current to a ribbon (24'), the electrode voltage levels for a plurality of non-adjacent electrodes are combined to provide a resultant voltage level that is examined in threshold detector (72) to detect abnormalities. By so combining voltages, insignificant excursions in electrical characteristics as might result from minor ribbon imperfections are generally eliminated from the triggering of a shutdown response, while still retaining a rapid response for preventing further heat generation in those situations where a serious ribbon failure has occurred.
