Patent EP-0643730-A1 (EP)
Title: Functionalisation of polymers.
Inventor: BAMFORD CLEMENT HENRY
IPC: C08G85/00
Filed: 1993-06-04
Abstract: A process for the functionalisation of polymers is disclosed. Functionalisation takes place by reacting a polymer with a peroxidant, preferably the peroxydisulphate or monosulphate or sodium or potassium in an aqueous medium. The hydroxylated polymer can then be reacted with other materials, including biomolecules. Using the method of the invention, products e.g. catheters or oxygenators can be produced with improved properties hitherto unobtainable.

Abstract: D'après un procédé connu, on prépare la masse de fromage devant remplir des moules à fromage en introduisant le mélange de base de petit lait et de caillebotte dans un tube de drainage perforé, à partir duquel on retire le petit lait et on fait circuler la masse de fromage restante vers le bas pour la recueillir dans des moules à fromage qu'on transfère ensuite pour effectuer le pressage ordinaire des blocs de caillebotte obtenus. On a cependant découvert que ce procédé présente différents problèmes en ce qui concerne la fermentation périphérique et l'invention permet d'apporter une solution à ces problèmes au moyen d'un système de production tout à fait nouveau et extrêmement efficace.

Inventor: BANNIZA THOMAS
IPC: H03K5/133
Filed: 1994-02-24
Abstract: When delay circuits consisting of an iterative circuit of gates are constructed as CMOS circuits, they have the disadvantage that the typical delay time of one CMOS gate deviates by a factor of between 0.5 and 2.0 as a function of temperature changes and changes in the operating voltage and of changes in the process speed and thus necessitates a wide tolerance range of the delay time in a delay circuit. The delay time is essentially determined by the RC product of the dynamic output impedance of the driving gate and the input capacitance of the driven gate. According to the invention, the output current of a CMOS gate is kept constant under different operating conditions by means of constant current sources implemented by current balancing circuits. Thus, the output impedance also remains constant and the tolerance range of the gate transit time is thus significantly restricted. This allows a delay circuit having narrow tolerances to be produced in CMOS technology, omitting non-CMOS-typical effects and expensive manufacturer-specific additional processes. <IMAGE>

Abstract: In a chatter monitoring system for twin drives of rolling stands, vibrations of the upper drive (2, 4, 6, 8) and of the lower drive (3, 5, 7, 9) are detected and monitored to determine whether they exceed a predetermined amplitude. If they do exceed the said amplitude, a chatter detection signal is generated. In order to prevent incorrect generation of the chatter detection signal as a consequence of stock entry vibrations, the frequencies of the vibrations of the upper drive (2, 4, 6, 8) and of the lower drive (3, 5, 7, 9) are monitored for equality; if their frequency is equal, the chatter detection signal is suppressed. <IMAGE>

Abstract: Superconducting magnets (10) of a magnetic resonance imager create static magnetic fields through an examination region (12). Gradient magnetic field coils (30) under control of a gradient magnetic field control (42) generate gradient magnetic fields across the examination region (12), as a whole. A plurality of surface coils (36, 38) receive radio frequency signals from each of two distinct subregions within the examination region (12). The two receiver coils are connected with separate receivers (60₁, 60₂) which demodulate the received magnetic resonance signals. The magnetic resonance signals are reconstructed (76) into an imager representation (80, 82) of the first and second subregions. In the embodiment of Figures 1 and 2, a radio frequency transmitter (40) and a whole body coil (32) generate and manipulate the magnetic resonance signals within the first and second subregions. In other embodiments, a plurality of transmitters (40₁, 40₂...) convey RF signals to the surface coils such that the surface coils operate in both a transmit and receive mode. Regardless whether a single transmitter or a series of transmitters is utilized, a sequence control (44) controls the transmitter(s) and the gradient control (42) to conduct conventional magnetic resonance imaging sequences in coordination in both subregions.

Title: Intelligent power switcher.
Inventor: SCHREIBER PAUL T
IPC: H02J13/00
Filed: 1994-01-07
Abstract: An intelligent power switching system for controlling the electrical connection of a power source to each of a plurality of outputs, such as personal computer components or electronic entertainment equipment. Switch circuitry is coupled to relay circuitry for generating signals responsive to user commands to select an "on" or "off" state with respect to each output. A processor receives switching signals and generates control signals to effect actuation of the relays. Responsive to user programming commands, the processor stores the switching signals, their sequence and the time delay between their generation. Responsive to a subsequent abbreviated user "power-on" command, the processor generates control signals by reading the stored switching signals, their sequence and time delay, and automatically actuates the relays with respect to each output in the same order and with the same time delay as defined by the user programming commands. A "power off" command causes the relays to be actuated in the reverse order.
