Inventor: WALKER HAROLD R
IPC: H04L27/227
Filed: 1988-01-18
Abstract: A high speed data transmission system for transmitting a binary data signal over a communications path, the binary data signal clocked at a given period, comprising encoding means (10) responsive to a binary NRZ input data signal to provide at an output an encoded digital signal having time periods greater than multiples of the clock period and at a given bit rate whereby the encoded signal occupies a lesser effective bandwidth than the NRZ signal alone, the lesser effective bandwidth being 1/2 to 1/3 that of the NRZ signal, a balanced modulator having an input responsive to the encoded signal and another input adapted to receive a carrier frequency signal to provide at an output a double sideband suppressed carrier signal shifting in phase 180 degrees with changes in the encoded signal, a filter (18) coupled to the output of the balanced modulator to provide a narrow bandwidth less than 1/2 the maximum bandwidth of the sideband signal and by which the carrier frequency and low frequencies are prevented from propagating to reject all sideband frequency components which are lower than 1/4 the bit rate and which are higher than 1/2 the bit rate of the encoded signal to provide at an output a narrow sideband signal for transmission characterized in that transitions between binary levels in the encoded signal are manifested by distinct phase changes in the single sideband signal, the filtering means operative to minimize phase distortion within the sideband signal, while passing only a part of one of the sidebands.

Abstract: The block-formed basidiomycete (10) of the present invention is formed by a block of basidiomycetous spawns, and its upper face (14) which is opposite side of the root section is a cut face or formed like a surface of cauliflowers or broccolis. 
     Spawns agglutinate to one another to form a block, preferably they extend from root side to upward almost in parallel and agglutinate. 
     The method of cultivating the block-formed basidiomycete comprises the following steps:
     (a) Filling media (16) in a cultivation bottle (18);   (b) sterilizing the media;   (c) inoculating seed spawns (24) on the media to cultivate spawns;   (d) removing part of the seed spawns to form a bed after the cultivation;   (e) producing many projected primordia (28) as spawns tissues on the bed by propagating the spawns in a vegetation room after forming the bed; and   (f) agglutinating the primordia by plumping them, after formation, under conditions of shortage of oxygen and surplus of carbon dioxide thereby to suppress production of fruiting bodies.

Abstract: A process for ecologically beneficial and hygienic disposal of (excess) sludge from communal and industrial sewage works, and a sludge treatment works for carrying out the process are described. The dilute sludge 1 of about 5% T.S. accumulating in a sewage works 2 is dewatered to 3 to 35% in a dewatering device, and the dewatered sludge is at least partially dried to 6 to 85% T.S. in a sludge drying device 6 and made storable. The waste heat obtained in the sludge drying device 6 is used in prewarmers 5 for warming the sludge, just as the centrifugate (line 14) separated from the prewarmed sludge in the dewatering device 3 is used to warm the sludge in a prewarmer 4, the centrifugate then being subjected to decomposition in an anaerobic step 7. Owing to the closed energy circulation, the energy needed in the works generates itself. The closed circulation guarantees the odour-free treatment of sludge, and the heat treatment of the sludge can be equated to a thermal sterilisation of the same. <IMAGE>

Abstract: Un procédé et un dispositif servent à produire des corps creux et volumineux à parois stratifiées en plastique. Afin de réduire le coût du procédé et de son contrôle, et d'obtenir un profil uniforme des couches formant la paroi stratifiée, plusieurs couches de matériau sont rassemblées à l'intérieur d'un piston annulaire radialement mobile de façon à former une masse fondue stratifiée. La masse fondue stratifiée s'écoule à l'intérieur du piston annulaire, se dilatant en entonnoir vers une chambre annulaire de stockage. Le piston annulaire est repoussé en arrière par la masse fondue, celle-ci étant extrudée à travers une filière par l'avancement du piston annulaire, formant ainsi un extrudat.

The antigens are purified, used to monitor the condition of cancer patients, and production of antibodies and treatments employing those antibodies are described. It is also disclosed that RAAs are expressed by M. hyorhinis and may be expressed by expression of provided nucleotide sequences in recombinant host cells. RAAs and nucleic acids encoding RAAs (or portions thereof) and RAAbs may be used in diagnostic assays and immunotherapy.

Abstract: A motor stop control device for stopping the motor includes a pulse generator (2) for generating a pulse signal (PG) having a pulse width which is in relation to the speed of the motor, a CPU (3), and a drive (4) for driving the motor. When a motor stop command signal is produced during the motor being rotated forward, CPU (3) operates the drive (4) to produce a counter drive torque, and, at the same time, CPU starts to compare the pulse width of the present pulse signal with that of the previous pulse signal, and produces a terminate signal when the pulse width of the present pulse signal becomes shorter than that of the previous cycle. When the terminate signal is produced, the drive (4) stops to produces the counter drive torque.

Abstract: In fluid flow stabilizing apparatus for establishing laminar flow, a plurality of stabilizer units (43-53) are disposed adjacent one another in a fluid flow path. Each includes a plurality of tubules (19, 21) in a particular pattern. The relative positions of the tubules are adjustable by changing the relative orientations of the stabilizer units, or by replacing one of the units with another having a different pattern of tubules. Such positional adjustments bring various ones of the tubules (19, 21) in one of the units into fluid communication with various ones of the tubules in another of the units to define a plurality of stabilizer fluid flow paths each having a length-to-EHR ratio high enough to assure laminar fluid flow. The lengths of the stabilizer flow paths can be increased by inserting additional stabilizer units into the primary flow path. The apparatus can be used in conjunction with a fluid mass flow meter (63-65) and a control valve (67) to provide a fluid mass flow controller.

Abstract: As a result of ever-greater miniaturisation, the width of conducting paths (7) has now reached a range of approximately 50 to 70  mu m. The conducting path configurations, which have specific meandering and periodic forms, must be bridged and repaired in the event of an unavoidable interruption to the conducting path by preforms (2) congruent with this point. Stamping methods, in which the punch has the same shape as the stamped part, cannot be used for producing such a preform (2) since such thin punches cannot withstand the stresses in the tool. According to the invention, a negative punching method is disclosed which produces one or more preforms (2) in the form of the stationary remaining web after two punching operations by means of a comparatively wide punch (3) combined with a specific feed (V). With this method it is possible to process hard-soldered plated metal strips (14), usually copper strips. Given a 20  mu m thick copper foil, the clearance for burr-free cutting is between 0 and 2  mu m.
