Title: Jumper switch means for electrolyzers electrically connected in series
Inventor: PILLET MICHEL
IPC: C25B9/04
Filed: 1994-07-11
Abstract: NOVEL JUMPER SWITCH MEANS FOR ELECTROLYZERS ELECTRICALLY CONNECTED IN SERIES     ABSTRACT            The novel jumper switch means of the invention is directed to by-passing an electrolyzer in a row of electrolyzers electrically connected in series to permit removal of the by-passed electrolyzer for maintenance. The jumper switch means comprises one or more internal bus bars connected to suitable arrays of switches. Said internal bus bars are dimensioned in such a way that when substantially all the electrolysis current flows through the jumper switch means, the voltage at its two connection terminals and therefore at the contact points of the by-passed electrolyzer, is close to, but in any case lower than the voltage spontaneously reached by the electrolyzer when electrolysis current is no more fed. Further, the present invention offers the possibility of housing said array of switches and said internal bus bars in a structure having a U-shape wherein the planar part has a limited height. Said limited height does not hinder the lateral removal of the by-passed electrolyzer by a suitable fork-lift truck.

Abstract: In a multipulse processing device for achieving a high encoding efficiency without using a high sampling frequency for an input signal and with a great degree of freedom given to positions of multipulses, an input speech signal is subjected by an LPC analyzer/processor 3 to LPC analysis of each analysis frame for extraction of LPC coefficients after sampled by an A/D converter 2.      Multipulses are retrieved as a result of decision by a multipulse analyzer 20 with a degree of freedom given relative to sampling points of a sampled speech signal supplied through an auditorily weighting filter 4.      Encoded by an encoder 41 and together with k parameters used as an example of the LPC coefficients, retrieved multipulses are multiplexed by a multiplexer 42 for delivery to a synthesis side. A multipulse waveform synthesizer 45 synthesizes a waveform by using decoded multipulse data and the LPC coefficients.

Title: Human papillomavirus detection assay
Inventor: BROWN JANICE T
IPC: C12Q1/70
Filed: 1994-05-06
Abstract: A two-step nucleic acid hybridization probe assay for certain types of human papilloma virus (HPV) associated with cervical cell dysplasia and malignancy comprises a fluid phase capture hybridization step in which amplified specific gene E6/E7 messenger RNA from a biological specimen is hybridized to a biotinylated capture reagent to form a complex, attachment of the capture reagent complex to a solid phase by reaction with immobilized streptavidin, a second hybridization step in which a virus type-specific enzyme-conjugated detection probe hybridizes with the complexed amplified messenger RNA, and detection of the complexed detection probe by color or fluorophor production following a wash of the solid phase and addition of an appropriate chromogenic or fluorogenic substrate.    The assay has enhanced sensitivity compared to conventional tests and is specific for actual expression of HPV oncogenes in cervical specimens, and not merely indicative of viral presence.

Inventor: TOMBA CHARLES P
IPC: C25B11/02
Filed: 1995-09-08
Abstract: Electrodes in plate form can be electrocatalytically coated and secured to a current distributor, such as by welding to a base plate, and may be serviceable, e.g., as anodes, in cells electrolyzing brine.  Recoating of plate electrodes can require removal from the cell, removal of old coating, application of fresh coating, then returning and securing the freshly coated electrodes to the cell. There are now provided envelopes for covering the original electrode plates.  The original plates thus do not need to be separated from a base member of the cell. The envelopes can have an electrocatalytic coating on their outer surfaces.  The resulting electrodes are thus a combination of an old inner plate and a new outer envelope, with an outer surface coating on the envelope. The envelopes can be secured to the inner plate and/or to a current distributor such as a base plate.

Title: Active noise and vibration control system accounting for time varying plant, using residual signal to create probe signal
Inventor: COLEMAN RONALD BRUCE
IPC: F16F15/02
Filed: 1995-11-06
Abstract: An active noise and vibration control system is constructed such that the residual signal from the residual sensor is fed back into the controller and used to generate the probe signal.          Measurements of the residual signal are used to create a related signal, which has the same magnitude spectrum as the residual signal, but which is phase-uncorrelated with the residual signal.         This latter signal is filtered by a shaping filter and attenuated to produce the desired probe signal.  The characteristics of the shaping filter and the attenuator are chosen such that when the probe signal is filtered by the plant transfer function, its contribution to the magnitude spectrum of the residual signal is uniformly below the measured magnitude spectrum of the residual by a prescribed amount (for example, 6 dB) over the entire involved frequency range.  The probe signal is then used to obtain a current estimate of the plant transfer function.

Abstract: A method of providing multi-switch business  group (MBG)  services  at  each  of  a  plurality  of  locations  is described.   The MBG services can be provided for calls made from a calling party served by an originating switch at one location to a called party served by a terminating switch at a location serviced by an inter-exchange carrier (IEC). When the calling  party  goes  off-hook,  a  determination  is  made  of whether the call is made from a centrex line.   Digits dialed by the calling party are then collected at the originating switch.   A determination is then made of whether the dialed digits contain an access code indicative that the call is to be routed to one of the plurality of locations which is served by an IEC.   If the call is to be routed via an IEC,  the initial address message  (IAM)  required for the IEC call,  is modified to include MBG service information.  This will permit MBG services to be offered between the calling party and the called party over public CCS7 trunks routed via an IEC.
