Title: Flow injection analysis method and apparatus thereof
IPC: G01N35/08
Filed: 1988-08-03
Granted: 1993-08-10
Abstract: Abstract of the Disclosure A novel and highly efficient flow injection analysis method is disclosed, in which in order to attain an extreme-ly high reaction rate of sample and reagent solutions at a reaction line, the solutions are injectedly supplied thereto alternately and respectively at a predetermined trace amount through independent two flow lines which are kept so as not to produce pulsation within the solutions.  A thermostat bath accommodating the reaction line and a back pressure coil connected to the flow lines also make the aforemen-tioned reaction rate stable and regular.  Spectrophotometric flow cell succeeding the flow lines for the analytical determination of the sample solution has a specific range of optical path length and such optical path diameter which is widely diverged from its inlet.

Abstract: It is disclosed for a balance with a scale on top based on the principle of the electromagnetic compensation of force with a system carrier fixed to the housing, with a load receiver, with two guide rods which connect the load receiver to the system carrier in a vertically movable direction as parallel guide, whereby the stem carrier, the two guide rods and the load receiver are designed as a one-piece casting, with a translation lever and with a coupling element between load receiver and translation lever, whereby the force from the load receiver corresponding to the mass of the weighed material is transferred via the coupling element to the shorter lever arm of the translation lever and the coil of the electromagnetic compensation of force is fastened to the longer lever arm of the translation lever that the system carrier comprise lateral projections which extend into the area between the guide rod arms.  This achieves a distinct reinforcement of the system carrier without having to increase the outer dimensions of the system.  The stability of the entire system can be further increased by means of further reinforcement measures in the load receiver and in the guide rod arms.

Abstract: Abstract of the Disclosure An optical waveguide junction including a multimode input waveguide and a plurality of n spaced apart output waveguides, disposed on a substrate. Each of the output waveguides has a different propagation constant, (e.g., by having different widths or indices of refraction), so that the input modes of optical radiation are sorted in a predetermined way into n groups of output modes corresponding to the n output waveguides. If the input waveguide is excited with optical radiation of different wavelengths, the output waveguides may be tailored with specific widths and indices of refraction to sort the input radiation into the n output waveguides as a function of wavelength, thereby demultiplexing the input optical signal. More generally, the junction may also be utilized with m input waveguides and n output waveguides to implement routing, switching, modulation, and wavelength multiplexing/demultiplexing.

Title: Method of preparing a silica gel supported metallocene alumoxane catalyst
Inventor: CHANG MAIN
IPC: C08F4/648
Filed: 1989-03-14
Granted: 1994-10-11
Abstract: ABSTRACT OF THE DISCLOSURE    This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the slurry, gas or liquid phase polymerization of olefins.  The invention particularly relates to the use of silica gel containing from about 10 to about 50 per cent by weight adsorbed water as the catalyst support material.  It has been found that such silica gel may be safely added to an aluminum trialkyl solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system.  An alumoxane coated silica gel is formed to which a metallocene may be added.  The resulting material can either  be  used  in  this  slurry state  for slurry polymerization or  can be  used  for  liquid phase polymerization of olefins.

Abstract: A sobriety interlock (1) with bypass detec-tion and recording is disclosed.  The interlock is connectable to a machine such as a vehicle (115) and normally operates to disable the machine from starting unless one or more preconditions, such as the passage of a breath sobriety test, is satisfied.  In the event the interlock is bypassed, i.e. the machine started without a prerequisite condition being satisfied, the bypass event is detected and recorded.  The record of bypass events preferably includes an indication of each time interval, such as a day, during which at least one bypass event took place as well as the total number of bypass events detected since the sobriety interlock (1) was installed or last serviced.  Also disclosed is a remote service device (56) connectable to the interlock by service personnel and useful for such purposes as reading and/or clearing the record of bypass attempts.

Abstract: "Scrambled Communication System Using Adaptive Transversal Filters For Descrambling Received Signals"                  ABSTRACT OF THE DISCLOSURE In a scrambled communication system, a transmitting station generates a scrambling noise having a periodically recurrent series of noise patterns and scrambles an information signal by simply summing the scrambling noise to the information signal so that the information signal is totally unintelligible by an interceptor. At a receiving station, a noise cancelling signal is generated by an adaptive transversal filter and supplied to a subtractor where it is combined with the scrambled signal to recover the information signal. For generating the noise cancelling signal, a descrambling noise identical to the scrambling noise is generated. The filter has a tapped-delay line for receiving the descrambling noise and a plurality of variable tap weights connected respectively to taps of the tapped-delay line. The outputs of the tap weights are summed to produce the noise cancelling signal which corresponds to the scrambling noise if the tape weights are adjusted to optimum tap coefficients which are derived from the descrambling noise and from the output of the subtractor. The repetition frequency and noise pattern are the key for descrambling the scrambled signal.

Abstract: An electrical insulator comprising a cylindrical core (2) of an insulating refractory material, such as porcelain, onto a portion of the curved surface of which a sleeve (8) of insulating polymeric material is fitted. Metal end-caps (4), for electrically connecting the insulator, are fitted to the ends of the porcelain core such that there is an exposed portion (10) of the curved surface of the core between the sleeve and each end-cap. Thus, any damaging electrical activity which takes place at the metal end-caps is directed primarily onto the surface of the porcelain core (2), and not onto the surface of the electrically vulnerable polymeric sleeve (8), which serves to protect mechanically the relatively brittle porcelain core. Optionally, the polymeric sleeve (8) may have a convoluted or a shedded outer surface (12) to increase the leakage path length of the insulator, or to prevent the formation of a continuous moisture path, or both.
