Abstract: An anchor rod for supporting walls, bulkheads and the like, comprises: an anchoring body to be cemented to the ground, at the bottom of a hole for the rod, by burying it into a casting of cement mixture, forming therewith the anchor bulb of the rod; traction cables connecting said anchoring body to a head-piece being fixed to the wall or like to be supported; two pipes containing and protecting said cables inside said hole, the first of said pipes carrying centering members, distributed throughout its length, and an inflatable plugging sleeve close to its end opposite to the head-piece, while the second pipe is telescoped into the first one, in correspondence of the end; and one pipe for feeding said cement mixture to form said bulb. The anchoring body consists of a frustoconical element, connected with its minor base to the end of said second pipe and housing, at its major outer base, a connection plate for the traction cables, being crossed by the pipe for feeding the cement mixture.

Abstract: A combustion chamber (20) of the firing installation is provided with a fuel supply (22) and a primary air supply (24). The outlet of the combustion chamber is connected to a fire space (26) which has a secondary air supply point (28) and a tertiary air supply point (30) with in each case downstream heat-extraction points (32) or (34). The outlet of the flame duct (36) thus formed is connected to a convective heat-extraction point (38), the outlet of which on the flue-gas side is designated by (40). The flame duct (36) is at least partially delimited by refractory ceramic walls (42) and runs out downstream from the fire space (26) in an uncooled mixing space (46). Between the combustion chamber (20) and the fire space (26), a heat-extraction point (48) is connected into the flow path (44) of the combustion gases. In this arrangement, the combustion of the fuel runs in a temporally and spatially extended manner, so that a complete combustion is achieved without inadmissibly high temperatures in spite of a low air excess. The discharge both of uncombusted gases and of nitrogen oxides and sulphur trioxide is thus avoided to a great extent. <IMAGE>

Abstract: An optical scanner for scanning an image on a document to produce an electrical signal representing the image density of the image at successively scanned points positioned along a scan line on the document includes a platen for supporting the document in a scan plane. A rotatable mirror in the scanner optical system is rotated at a non-uniform angular velocity to scan the document at a controlled scan rate which may be selected as a uniform scan rate. Rotation of the mirror is controlled by means of a servo control loop responsive to a reference signal and to the output of a reference transducer which receives light from a reference grating as the mirror is rotated.

Abstract: 3',4'-Dideoxy derivative and 1-N-((S)- alpha -hydroxy- omega -aminoalkanoyl)-3',4'-dideoxy derivative of kanamycin A are now synthetized from kanamycin A and show a wider and/or higher antibacterial activity than the parent kanamycin A so that they are useful in therapeutic treatment of infections by gram-negative and gram-positive bacteria, including drug-resistant strains thereof. The production of these new derivatives may be made by preparing a protected kanamycin A derivative having its 3'- and 4'-hydroxyl groups unprotected and having its all or substantially all other functional groups protected from the initial material, kanamycin A, sulfonylating the 3'- and 4'-hydroxyl groups, removing the 3'- and 4'-sulfonyloxy groups from the resulting 3',4'-di-sulfonic acid ester product to give a 3'-eno-kanamycin A derivative, hydrogenating the 3'-eno-kanamycin A derivative to saturate the 3',4'-unsaturated bond and to yield a protected 3',4'-dideoxykanamycin A product, followed by removal of the remainiing protective groups, and optionally further followed by 1-N-acylation of the 1-amino group of the resulting 3',4'-dideoxykanamycin A with an (S)- alpha -hydroxy- omega -aminoalkanoic acid or its reactive equivalent.

Abstract: A system for transmitting n-level data signals by means of an angle-modulated carrier having a constant amplitude and a continuous phase. The constant amplitude enables amplification in non-linear transmitter output stages. Associated with the n-levels are k(k>n) phase variations in accordance with such a rule, depending on preceding phase variations, that the spectrum of the angle-modulated signal becomes narrower. In a symbol interval the phase of the carrier changes by an amount from the sequence extending from -(k-1) pi /n to (k+1) pi /n in increments of 2 pi /n. The receiver is formed by a differential n-phase receiver. The system is used inter alia for radio transmission of digital information.

Abstract: An apparatus for the manufacture of halate, such as sodium chlorate, includes an electrolytic cell having a plurality of anodes and cathodes, clearance passageways between which have electrolyte, hypohalite and gaseous electrolysis product, principally hydrogen, moving upwardly between them, an enclosure covering the tops of at least four such passageways and narrowing down to a passageway extending upwardly from the top of the enclosure and a downward passage for circulation of electrolyte which includes an upper baffled portion and a lower unbaffled portion, the unbaffled part being alongside the electrodes and extending to the bottom of the cell, from which electrolyte is drawn upwardly past the electrodes. Natural circulation due to gravity flow and density differences between the liquid electrolyte and that entrained in gas or having gas entrained in it is normally sufficient so that stirring or pumping means are not required. The invention provides a means for converting higher current density cells to lower current density cells so as to be more energy efficient. In such conversions additional anode-cathode units are installed between those already in place and gases generated from them are collected with gases generated from an adjacent originally present anode-cathode unit and are moved upwardly with entrained liquid through previously existing passages while other circulating electrolyte is moved downwardly, also through previously existing passageways, baffled and unbaffled. Other aspects of the invention relate to particular types of spacers between electrodes and to more energy efficient lower current density electrochemical processes for manufacturing sodium chlorate.

Title: Motor driven machine control system - uses feedback of load vibration acceleration to damp vibrations using phase compensation signals
Inventor: FUTAMI S
IPC: H02P7/06
Filed: 1983-02-14
Abstract: The control system is used for motor driven machines, esp. precision machine tools and reduces vibration by converting detected vibration acceleration to phase compensation signals supplied as feedback to the motor drive control. A motor drives a load via a transmission system in response to signals from a speed command unit supplied via a subtractor and speed controller. Acceleration of vibration in the load is detected and converted to electrical signals proportional to the acceleration. These signals are converted to suitable phase compensation signals for damping vibration by a phase compensator and gain compensation circuit and supplied to the subtractor to cause required adjustment of motor drive.
