Abstract: In known stock purifying apparatus centrifugal force is utilized to separate out the impurities, the impure stock being introduced into the centrifuging chamber of the apparatus at the radially outermost zone and thus requiring to be at a suitable pressure to counter centrifugal forces. In the present apparatus the impure stock is introduced via an inlet (16) in the form of a scroll (30), the scroll leading into the centrifuging chamber (10) at the axially central region thereof where the lowest pressure prevails. The scroll imparts a spiral motion to the stock so that it easily merges with the stock which is being centrifuged by an impeller (20) in an end wall (14) opposite the scroll inlet. Due to the introduction of the impure stock in a low pressure region, running costs are reduced as the impure stock does not require pressurising to the extent required in the relevant prior art. <IMAGE>

Abstract: An anode composition is used as the sole source of aluminum and comprises an aluminous material such as aluminum oxide and a reducing agent such as carbon. Electrodeposition is achieved at low temperatures and low electrical potential by the electrolysis in a fused salt containing the composite anode. The anode reacts to produce aluminum ions during the electrolysis, aluminum compound ionized at the anode is electrolytically reduced to molten aluminum at the cathode and an anion formed at the anode reacts to produce CO2 gas at the anode. In one operational mode a porous membrane passes electrolyte or other dissolved material while withholding undissolved impurities. Aluminum may be electrodeposited, at a temperature as low as the melting point of the metal and with the use of an all fluoride containing bath and the composite anode. Dimensionally stable cells for the electrodeposition have sloped walls forming electrodes that permit the maintenance of a reduced anode current density as well as anode- cathode spacing when using the low temperature non-aggressive baths permissible with the particular composite anode composition.

Abstract: An electronic postal meter has a control unit, an accounting unit and a printing unit, each incorporating a CPU having a separate crystal controlled clock. Communication between the units is serial character asynchronous, bit synchronous, in message form, with the bits of the messages being timed in accordance with a given schedule for synchronous control. The messages themselves, upon receipt by a receiver, are returned bit by bit to the transmitter, for checking, whereupon the transmitter sends a no-error pulse upon successful comparison of the transmitted message and the message received from the receiver. All control and data signals utilize the same pair of conductors in each direction with precisely defined timing for control.

Date Jul. 23, 1981.In a guide track (1) there travel a plurality of carts (2) which are driven by an endless chain (8). Each cart (2) carries a load bearing tray (3), which is intended to receive a package or the like. At predetermined discharge locations the load bearing trays are tilted into an inclined position so that the packages slide into a collecting container. To the load bearing tray there is attached a shaft (12) which extends diagonally to the load bearing tray surface, and which is journalled rotatably in a bearing (11). To tilt the load bearing tray (3) the shaft (12) is tilted by a drive disc (15) which is connected to the shaft (12) through a shaft (14) and a universal joint (13). The drive disc (15) itself is braked by means of electromechanical or mechanical guide rails at predetermined discharge locations upon passage of the cart and is thereby rotated. The apparatus for tilting the load bearing trays is very simple and functions largely trouble free.

Abstract: In an emergency power unit for an alternating current consumer, there are supplied a connection (9) for an alternating current generator (10), a battery (5), which can be charged by rectified current from the alternating current generator (10), a controllable bidirectional converter unit (6), which is located between the said battery and a consumer connection (2), an alternating voltage regulator (13), which stabilizes the alternating voltage on the alternating voltage side (3) of the bidirectional converter unit (6) by means of pulse-width modulation, and a battery voltage regulator (12). The alternating current generator (10) can be connected, in parallel, to the alternating voltage side of the bidirectional converter unit (6), and a current-limiting resistor (8) is located between the alternating voltage side (3) of the bidirectional converter unit (6) and the alternating current generator connection (9). In order to achieve galvanic isolation between the bidirectional converter unit and the alternating current generator, and between the consumer (1) and the alternating voltage generator (10), the current-limiting resistor is designed as a leakage-reactance transformer (8') which has three windings. Of these, one winding (31) is connected directly to the alternating voltage side (3) of the bidirectional converter unit, the second winding (32) is connected to the alternating current generator connections (9, 9a) and the third winding is connected to the consumer connections (2, 2a). The leakage-reactance transformer effects not only galvanic isolation, but at the same time effects the required current-limitation as a consequence of its leakage-inductance.

Abstract: A structure of a tank for storage of a suspension is improved in that a conical bottom partition wall is disposed in the bottom portion within a cylindrical outer shell of the tank with its lowest point located substantially at the center of the horizontal cross-section of the cylindrical outer shell. An upwardly extending side wall is provided along the circumference of the conical bottom partition wall and is disposed with an appropriate interval spaced from an inner surface of the cylindrical outer shell. A cover consisting of an annular top wall inclined substantially in parallel to the conical bottom partition wall and a downwardly extending side wall is fixedly secured to the inner surface of the cylindrical outer shell so as to cover the upwardly extending side wall with an appropriate interval spaced therefrom. A bent pressure communication chamber, extending from the upper side of the circumferential portion of the conical bottom partition wall to the lower side of the same partition wall, is useful for separating a suspension stored in the tank from a liquid preliminarily filled in the space under the conical partition wall and establishing approximate pressure balance between the upper and lower sides of the conical bottom partition wall. The stored suspension can be conveniently discharged through a discharge pipe extending from the lowest point of the conical bottom partition wall to the outside of the cylindrical outer shell.

Abstract: The separate regulator circuit contains a hot water pipe from a heating boiler, a housing contg. the heat sensor (20) connected to the hot water pipe, a return pipe running from the sensor housing back to the boiler, and a throttle valve fitted in the return pipe. The throttle valve is controlled by a room thermostat so that if a temp. appertains which is lower than that set for the room it opens, allowing hot water to circulate in the regulator circuit. This causes the sensor to expand, activating the shunt valve (1) so that the proportion of hot water in the radiator circuit increases. The shunt valve comprises a body (5) formed as an upwardly open cylinder with closed bottom end, and having a row of through apertures (6). On the valve body exterior, the apertures are joined to each other by a ring channel.
