Granted: 1998-04-28
Abstract: For a squirrel-cage rotor of an electric machine, having a cage that passes through the stack axially and is made of electrically well-conductive short-circuit rods that are connected by short-circuit rings at the ends projecting from the stack, oscillation problems that result during operation with frequency converters are intended to be solved.  In addition, higher natural torsion frequencies are intended to be achieved on the rotor, that is, the construction is to be made less sensitive by simple modifications to the squirrel cage in order to prevent the resonance effects.  This object is attained in that respectively two, three or more short-circuit rods are guided together to rod assemblies at their ends, and these are connected to the short-circuit rings with material-to-material bonding.  Advantageous embodiments for the structure of two-, three- and four-rod assemblies can be taken from the dependent claims.

Title: Apparatus for producing a nonwoven spun-filament web of aerodynamically stretched filament of a plastic
Inventor: GEUS HANS GEORG
IPC: D01D5/098
Filed: 1994-04-15
Granted: 1999-03-23
Abstract: ABSTRACT OF THE DISCLOSURE         A spun-filament nonwoven web is deposited on a sieve belt from a spinning head producing a curtain of thermoplastic filaments which traverse a cooling chamber by drawing the filaments in a drawing nozzle separate from the cooling chamber and passing the filaments through a delivery unit and the form of a jet pump, air flow through which is controlled at least in part by a suction blower below that sieve belt. Significantly higher web speeds and, thus, increased output is achievable without detriment to the quality of the nonwoven web.

Abstract: This device includes at least one transformer (9, 10, 11) supplied, at its primary (9) by a three-phase alternating current and delivering, on at least one secondary (10, 11), a three-phase current applied to rectifying means delivering, as output to the load, a rectified voltage and current, these rectifying means being of the type including, for each secondary, controlled semiconductor devices (15, 16). According to the invention, the rectifying means comprise a free-running circuit (19), the said controlled semiconductor devices being triggered with firing angles which are essentially variable, these being modified so as to increase the conduction period in the free-running circuit while at the same time decreasing the conduction period in the triggered semiconductor devices, and conversely, thus making it possible to deliver, to the load, an active power or a reactive power which is substantially constant despite variations in the impedance of the load. <IMAGE>

Title: Air-oxy-fuel burner method and apparatus
Inventor: YAP LOO T
IPC: F23D14/32
Filed: 1994-08-11
Granted: 1998-12-08
Abstract: The present invention provides an air-oxy-fuel method and apparatus in which fuel is burned in first and second stages  of  combustion having a  fuel-rich and fuel-lean stoichiometry, respectively, to reduce NOx emissions.  The fuel is burned in the first stage of combustion in oxygen. The combustion of the fuel is completed in the second stage of combustion in the presence of air.  Mixing of fuel and oxygen is effected by forming fuel and oxygen jets in close proximity to one another.  Air is then swirled around the fuel and oxygen jets at a swirl ratio of no less than about 0.6  so that combustion products of the first stage of combustion recirculate to obtain stable combustion of a very fuel-rich flame which is characterized by increased flame luminosity.   The use of air allows for a lesser degree of swirling than had a single oxidant been used in both the first and second stages of combustion because a greater mass of air is applied than oxygen.  This in turn allows the air to be swirled with a sufficient forward momentum to locate the second stage of combustion directly downstream of the first stage of combustion.

Abstract: Construction of a single gene encoding a signal-chain immunoglobulin-like molecule is described. This single-gene approach circumvents inefficiencies inherent in delivering two genes into a mammalian cell and in the assembly of a functional immunoglobulin molecule. It also facilitates ex vivo transfection of cells for gene-therapy protocols.  The single-chain protein comprises the heavy- and light-chain variable (V H and V L) domains of a monoclonal antibody covalently joined through a short linker peptide, while the carboxyl end of a V domain is linked to the amino terminus of a human constant region such as .gamma. 1 Fc, through the hinge region. The single-chain protein assembles into a dimeric molecule of ~ 120 kDa and is secreted into the culture fluid. The single-chain immunoglobulin-like protein shows similar antigen binding affinity to that of chimeric or parental antibody and mediates ADCC. This single-gene construct approach provides a way of generating an immunoglobulin- like molecule which retains the specificity, binding properties, and cytolytic activity of a parental monoclonal antibody, and thus is a useful therapeutic and diagnostic reagent against a range of antigens, such as human carcinomas.

This process ensures production of the LiM3+O2 and LiMn2O4, which are highly purified and have high crystallization degrees, in large quantities on a commercial scale. The thus produced LiNi3+O2 exhibits excellent charge-discharge characteristics as an active material of a positive electrode of a secondary battery.

Title: Congestion control method in atm network
Inventor: IKEDA CHINATSU
IPC: H04L47/22
Filed: 1994-12-21
Granted: 2000-05-16
Abstract: In the congestion control method, when a queue length of a node in a virtual channel set up in an ATM network is a first threshold or more, a source terminal in the virtual channel is instructed to decrease a transmission rate. When the queue length of a node is a second threshold or more which is greater than the first threshold, there is halted the transmission of data cells from the preceding nodes or source terminals to the bottleneck node.      In a method of decreasing the transmission rate, congestion data is added to the header of a data cell passing through a node where the data cell queue is the first threshold or more, and the destination terminal which has received the data cell containing the congestion data transmits a rate decreasing control cell to the source terminal through the network. Receiving the rate decreasing control cell, the source terminal lowers the transmission rate. In another way, in a node where a cell queue length is the first threshold or more, a rate decreasing control cell is generated and transmitted to the source terminal.

Title: Process and arrangement for the electrolytic deposition of metal layers
Inventor: SCHUMACHER ROLF
IPC: C25D21/14
Filed: 1994-12-23
Granted: 2003-09-02
Abstract: For the electrolytic deposition of uniform layers of metal having given physical-mechanical properties, particularly of copper, soluble anodes are not used, since their geometrical shape is changed by the deposition and therefore the distribution of the lines of force in the electrolytic cell are continuously changed.      In order to solve the problems occurring in this connection, a process has been proposed in which compounds of a redox system added to the plating solution are converted during the deposition on the insoluble anodes. The compounds produced in this connection dissolve new metal ions from a reservoir which contains parts of the metal to be deposited, so as again to supplement the metal ions removed form the solution by deposition.      The present invention describes a procedure in which, differing from the prior art, the addition compounds are not destroyed.
