IPC: H04L29/06
Filed: 1993-06-04
Abstract: 28 SERVEUR A HAUT DEBIT D E S C R I P T I F Pour augmenter le débit de transfert d'information d'une base (1) audio-visuelle à des demandeurs (9-11) multiples on propose, lorsqu'une requête à été effectuée par un demandeur, de ne pas satisfaire ce demandeur immédiatement mais de le faire attendre pendant une période donnée (17). Pendant cette période on détecte quels sont les autres demandeurs qui demandent la même séquence. Au bout d'une période d'attente on diffuse (22) à l'ensemble (19) de ces demandeurs la même séquence. On montre qu'en retardant un peu la diffusion on augmente dans des proportions très importantes le débit réel de diffusion de la base de données et sans par ailleurs avoir à modifier la technologie d'extraction des données de cette base.

Title: 3- and/or 4-substituted derivatives of quinic acid and a process for the production of 3- and/or 4-substituted derivatives of quinic acid
Inventor: HUYNH-BA TUONG
IPC: C07D307/00
Filed: 1993-07-23
Abstract: Abstract 3- and/or 4-substituted derivatives of quinic acid and a process for the production of 3- and/or 4-substituted derivatives of quinic acid 3- or 4-mono-, 1,3- or 1,4- or even 3,4-disubsti-tuted derivatives of quinic acid are produced by reac-tion of a hydroxycinnamic acid derivative, of which the phenol group(s)  is/are protected with a quinic acid derivative, to form an ester and the different reactivi-ties of the OH functions in the 3 and 4 positions are used to carry out the esterification selectively under low temperature conditions, after which the protective groups are cleaved under controlled acidity and tempera-ture conditions.  These conditions avoid any degradation or isomerization.  The process enables new quinides to be obtained in high yields.

Title: Electronic power regulator for an automotive alternator
Inventor: SCHULTZ ROY D
IPC: H02J7/14
Filed: 1993-10-13
Abstract: ABSTRACT OF THE DISCLOSURE      An automotive power control system which delivers a regulated  voltage  to  a  load  circuit  during  normal operation and which delivers maximum power when the demand  exceeds  the  alternator's  ability  to  supply adequate current to the load.  A duty-cycle- controlled DC-to-DC voltage converter reduces the alternator voltage to a level appropriate for charging the system battery and supplying low voltage loads.  When the rotational speed  of  the  alternator  is  adequate  to  generate sufficient load current, the voltage converter operates under the control of a first feedback circuit which compares the converter's output load voltage with a reference potential to generate an error signal which regulates the output voltage to a desired level.  When the output voltage falls below that desired level, a speed  signal  indicative  of the  speed at which the alternator is rotating is used to generate a control signal which is applied to the switching converter to vary the alternator output voltage and maximize the power obtained from the alternator at the sensed rotational speed.

Title: Method of predicting tumor response to therapy
Inventor: MORGAN LEE R
IPC: G01N33/50
Filed: 1992-04-24
Abstract: A method is disclosed for predicting response of a tumor patient to therapy, and selecting appropriate therapy for malignant neoplasms such as breast, ovarian and gastrointestinal cancer. A  sample of tumor cells is cultured in the presence of 10 µg/ml estradiol, and inhibition of cell growth in the culture paradoxically indicates an estrogen dependent tumor that will respond to antiestrogenic therapy. Another sample of tumor cells is cultured in the presence of a chemotherapeutic agent which predicts response of the tumor to in vivo administration of a cytotoxic agent.  The chemotherapeutic agent is preferably a cytotoxic drug, or a drug having both cytotoxic and antiestrogenic mechanisms of action.  A particularly suitable substance having both mechanisms of action is (I): wherein R1 is H, OH, OOC(CH2)2CO2H or CH3COO; R2 is C6H4OH, C6H4OCOCH3, C6H4OOC(CH2)CO2H, or C6H5; and X is C6H3-2,4(NO2)2, C6H5, C6H4-4(NO2), C6H4-3(NO2), or C6H3-2,4(NO2)2.  Predictive power of the assay is increased by combining information from the estradiol and chemotherapeutic assays. These assays are preferably performed in culture flasks having removable bases that function as conventional microscope slides.

Title: Metal halide lamp
Inventor: JENKINS ROBERT G
IPC: H01J61/30
Filed: 1993-12-21
Abstract: ABSTRACT     An arc tube for a metal halide discharge lamp is formed of titanium oxide doped vitreous silica.  In one embodiment of the invention the doped vitreous silica is fused quartz made from a melt doped with TiO2.  In a preferred embodiment, the concentration of titanium oxide in the vitreous silica is approximately 250 parts per million by weight.  Metal halide discharge lamps utilizing arc tubes formed from the doped vitreous silica demonstrate improved lumen output and lumen maintenance.

Title: Apparatus for transporting sheet-like products
Inventor: HANSCH EGON
IPC: B65H29/06
Filed: 1994-01-13
Abstract: An apparatus for transporting sheet-like products includes a belt conveyor with a flexible conveyor belt. The conveyor belt is driven in a conveying direction at a conveying speed. A takeover conveyor has individually controllable clamps which are arranged one behind the other on a carrying member.      The clamps are driven in a rotating direction, and the clamp mouths are directed in the takeover region forward in rotating direction. The products fed to the takeover region are in each case pressed against the conveyor belt by a pressing roller at the free end of the first clamping jaw of the clamp. Since the clamp speed of the clamps is greater than the conveying speed, the following clamp thus catches up with the held product and seizes it at the trailing edge.

Title: Methods of operating a hydraulically-actuated electronically-controlled fuel injection system adapted for starting an engine
Inventor: CAMPION ROBERT M
IPC: F02F7/00
Filed: 1991-12-23
Abstract: Methods of starting a hydraulically-actuated electronical-ly-controlled fuel injection system (10) are disclosed. One meth-od comprises the steps of pressurizing actuating fluid used to actuate a unit injector (18) and actuating an electrical actuator assembly (36) of the unit injector (18) to cause fuel injection on-ly when the pressure of the actuating fluid is at least equal to a selected minimum level. This method of the present invention ensures that the unit injector (18) does not diminish the pres-sure of the actuating fluid until the pressure has reached a se-lected minimum level required to effect fuel injection. This method allows the pumping capacity of the high pressure actu-ating fluid pump (332) to be minimized while ensuring quick starting of an engine (12) by the fuel system (10).
