Title: Hydroconversion catalyst
Inventor: VAN BALLEGOY CAROLUS M
IPC: B01J23/40
Filed: 1993-08-26
Abstract: A catalyst of use in hydroconversion processes comprises palladium supported on a silica-alumina carrier, which carrier has been prepared from an amorphous silica-alumina starting material having a pore volume of at least 1.0 ml/g. A process for the preparation of the aforementioned catalyst comprises preparing a carrier from an amorphous silica-alumina having a pore volume of at least 1.0 ml/g and impregnating the carrier so-formed with palladium by contacting the carrier with a palladium compound in the presence of a liquid, preferably under acidic conditions.

Title: Method and apparatus for growing biomass particles
Inventor: JEM KWAN-MIN
IPC: C12N5/071
Filed: 1993-01-15
Abstract: The present invention provides an improved method and apparatus for growing biomass particles (15), particularly microcarrier-bound cells, in an agitated suspension culture vessel (10) in which fresh culture medium is added and spent culture medium is withdrawn continuously or semi-continuously. The improvement comprises withdrawing the spent culture medium through a particle settling chamber (26) located within the vessel (10) and at least partially immersed in the agitated culture medium therewithin. The particle settling chamber (26) comprises a hollow container (27, 28) with a bottom opening (18) through which biomass particles (15), such as microcarrier-bound cells, settle by a gravity back into the agitated culture medium and a top opening (19) through which particle-free spent culture medium is withdrawn from the vessel (10). The settling chamber (26) is configured such that the fluid velocity of culture medium entering the settling chamber (26) through the bottom opening (18) is significantly less than the biomass p article settling velocity.
Patent CA-2110826-A1 (CA)
Inventor: ISHIZU FUMIO
IPC: H04L25/06
Filed: 1993-12-07
Abstract: A clock recovery circuit capable of outputting decision point data without causing any slip of a recovered clock in the case of operation in a continuous mode in a demodulator in which received signals are sampled by a fixed frequency clock to obtain the recovered clock and symbol data are demodulated by using this recovered clock. A shift register stores digital received signals obtained by an A/D conversion of quasi-coherent detection received signals, and a clock phase estimator calculates an estimated phase difference between an output value of a phase generator operated by the fixed frequency clock and a symbol clock of the received signals and outputs timing information and phase information of a decision point for discriminating the data of the received signals. An interpolator inputs the output signal of the clock phase estimator, takes in the digital received signals from the shift register and calculates decision point data by interpolation to output the same. The interpolator operates at the same cycle as the symbol clock on an average.

Title: Controlling Multiple Tool Positions with a Single Repeated Remote Command Signal
Inventor: SCHULTZ ROGER L
IPC: E21B34/16
Filed: 1993-12-17
Abstract: A system is provided for remotely controlling a downhole tool in a well. A plurality of substantially identical command signals are transmitted into the well. Each of the command signals is received at the downhole tool by a controller having information stored therein identifying an operative command signal signature associated with that tool. Upon comparing each command signal to the stored information and confirming that the command signal contains the operative command signal signature associated with that tool, a control signal is generated by the controller for each confirmed command signal. An operating element of the downhole tool is advanced one position in a repeating series of operational positions in response to each successive control signal generated by the controller.
