Patent EP-0100953-A1 (EP)
Inventor: GORLICH LOTHAR
IPC: C02F11/04
Filed: 1983-07-25
Abstract: The biological reactor contains in a vessel (11) a bundle (13) of tubes (15). The bundle (13) is formed by a plurality of plastic tubes (15) being of preferably square cross-section. The walls of the plastic tubes serve as growth surfaces for microorganisms. A distributing device (17) feeds the different ducts (18) evenly with liquid organic refuse. The ducts (18) are not completely filled. The liquid level in the reactor is at a certain distance from the top of the tubes (15). Accordingly, if one of the ducts (18) tends to clog, it is filled more than the remaining ducts so that in the clogging duct a hydrostatic pressure is created having the tendency to free the duct. This freeing of the duct is assisted by the control unit 58 which from time to time lowers the liquid level in the reactor and then increases it again.

Abstract: In an optical device an objective (1) is moved axially along its optical axis (2) relative to a frame (13) in a parallel guide (12) by means of first electro-magnetic actuating means (5) connected to the objective and second electro- magnetic actuating means (7-10) arranged on the frame, which first and second actuating means co-operate axially with each other by means of a radial magnetic field which is oriented transversely of the optical axis (2) and transversely of the direction of movement of the objective. In order to suppress vibrations caused by axial reactive forces transmitted from the second actuating means (7-10) to the frame (13), axially resilient damping means (16) are interposed between the frame (13) and at least a part (8) of the second actuating means (7-10). Surprisingly, the movements of the second actuating means (7-10) do not affect the position of the objective (1). This is because an axial displacement of the radial magnetic field relatively to the first actuating means (5) does not give rise to an axial movement of the objective (1).

Abstract: A data compressor compresses an input stream of data character signals by storing in a string table strings of data character signals encountered in the input stream. The compressor searches the input stream to determine the longest match to a stored string. Each stored string comprises a prefix string and an extension character where the extension character is the last character in the string and the prefix string comprises all but the extension character. Each string has a code signal associated therewith and a string is stored in the string table by, at least implicity, storing the code signal for the string, the code signal for the string prefix and the extension character. When the longest match between the input data character strem and the stored strings is determined, the code signal for the longest match is transmitted as the compressed code signal for the encountered string of characters and an extension string is stored in the string ta ble. The prefix of the extended string is the longest match and the extension character of the extended string is the next input data character signal following the longest match. Searching through the string table and entering extended strings therein is effected by a limited search hashing procedure. Decompression is effected by a decompressor that receives the compressed code signals and generates a string table similar to that constructed by the compressor to effect lookup of received code signals so as to recover the data character signals comprising a stored string. The decompressor string table is updated by storing a string having a prefix in accordance with a prior received code signal and an extension character in accordance with the first character of the currently recovered string.

Abstract: A method of fabricating an optical glass base material by injecting and depositing glass fine particles produced by chemically reacting glass stock which comprises means (2) for growing the glass fine particles in a depositing direction to form porous rod-shaped base material (24), support means (4) for supporting the porous rod-shaped base material (24) after growing, and heat treatment means (3) for sintering at least the outer periphery of the rod-shaped base material (24) in a semisintered state to harden the same before supporting the rod-shaped base material by said support means (4). Thus, since the rod-shaped base material (24) is held in a stable state through the support means (4) and the base material (24) has improved mechanical strength due to the semisintering hardening through the heat treating means (3) before being supported by the support means (4), the base material (24) is not deformed nor damaged in the supported state, and large quantities of base material may be fabricated.

Abstract: A telephone system having a remote microphone (82) and associated transmitter (80), and a network located receiver (60) for signals outgoing over the telephone network and including a local loudspeaker (28) to broadcast signals incoming over the telephone network wherein the loudspeaker audio level is controlled to vary with the level of the received microphone signal increases, and vice versa, allowing the user to control the loudspeaker level by adjusting mouth-to-microphone distance or speech loudness. In particular implementation the signal applied to the network from the remote microphone receiver is automatically attenuated above a certain level to match network requirements. The degree of attenuation is used to cause a corresponding increase in the loudspeaker volume level. Harmful feedback is avoided since loop gain remains constant. Proper microphone signal level and loudspeaker volume are assured by the reflex reaction of bringing the microphone closer to the mouth or speaking louder if loudspeaker volume is too soft.

Abstract: The device can be mounted in an aeration tank and essentially consists of a plurality of air distributors of low width (1), each of which is connected by a coupling (5) to a central air-distribution line (4). The air distributors (1) consist of a shell-like wall part (16) and of an aeration wall (2) fixed air-tight thereto. The aeration wall (2) consists of thin metal sheeting and is flat and has a large number of air-outlet openings (7) with a diameter below 0.3 mm and a depth of about 0.15 mm. For the aeration, a blower blows air into the line (4) and into the air distributors (1). The air emerges as fine bubbles in narrow strips out of the openings (7) and slowly rises in the liquid. The openings (7) are, by reason of their low depth, scarcely blocked by small blocking agents and bacteria even on long interruption of aeration. The aeration device is particularly suitable for intermittent aeration in effluents or sludge. <IMAGE>
