Abstract: A cleanroom conduit (44) is used for transporting products between two cleanroom environments through an area that is less clean than either cleanroom environments. The conduit is modular in nature and thus can be adapted for various distances between the two cleanrooms. Each modular section (10 & 30) has a perforated floor (12) for exhausting gas and contaminants out of the modular section. Additionally, each modular section (30) has a filter (38) attached to a wall, with an opening therein, for filtering the incoming gas that is being supplied recirculated through the conduit. In effect, the conduit is maintained as a mini-cleanroom such that products being moved from the first cleanroom through the conduit do not require a decontamination step before they can be reintroduced into the second cleanroom.

Abstract: An improved process for ethylene (co)polymerization is carried out in the presence of a catalyst obtained by reacting a Ziegler-Natta catalyst, or a component thereof, wherein at least a transition metal is π-bonded to an organic residue, with an alpha-olefin having the following general formula (II):
      wherein R 4  and R 5  are two substituents selected, independently, from linear, cyclic or branched aliphatic or aromatic hydrocarbon groups having from 1 to 12 carbon atoms, or they are linked to each other to form a substituted or non-substituted cyclic compound, comprising the vinyl carbon atom in a ring of from 3 to 8 carbon atoms. 
     The polymerization process allows productivity values to be obtained which are higher than those obtained with an analogous process carried out without the preliminary interaction with the above said alpha-olefin, while simultaneously allowing a complete freedom with regard to the choice of the monomer composition.

Abstract: A sailboat winch used for trimming lines of alternate sails, such as a jib and a spinnaker, has a drum (12) with upper and lower drum portions (16,22) of different diameters separated by a continuous radially projecting lip (24). The upper drum portion (16) has a first diameter and is used for trimming the jib at maximum power. The lower drum portion (22) has a diameter greater than the first diameter and is used for trimming the spinnaker lines. The radial extent of the lip (24) is sufficient to prevent a line (14), when wrapped on the lower drum (22), from slipping upwardly and becoming disengaged from the lower drum (22).

Abstract: In a polymerization process of at least one of monomers selected from the group consisting of conjugated diene compounds such as butadiene and vinylaromatic compounds such as styrene, an organolithium compound such as butyllithium is added to the polymerization system first in the presence of the monomer, and thereafter a secondary amine compound such as saturated cyclic imine is added thereto to produce a soluble initiator by bringing the both compound into contact with each other. Polymerization is carried out with the soluble initiator formed. The obtained high molecular weight polymer is modified with a coupling agent such as tin tetrachloride. The polymer obtained has a high molecular weight, a narrow molecular weight distribution, and controlled molecular weight, and exhibits remarkable coupling property, low hysteresis loss. The process provides a polymer having a consistent characteristic, regardless of production scale and procedures of adding materials.

Abstract: The regulator consists of a single shutter (5) with a spring (9), pivoted to the forward end of a housing (1) to form a duct (2) with a section which varies with the air pressure to maintain a constant flow rate. The shutter interacts with the duct housing so that the channel through which the air flows converges in the direction of the flow for all shutter positions. The shutter extends beyond the minimal section of the canal, and the housing has a wall which faces the shutter and is inclined towards the axis of the canal from front to rear. The wall (7) can be made adjustable to vary the air flow through the duct, and the channel (8) can be made with an axis which is inclined relative to that of the housing. During operation the position of the shutter varies with the force of the aid flow through an aperture (10) beneath it, maintaining the flow through the duct at a constant rate.

Abstract: The channel selection circuit uses a an electrical network for transmission of a stream of binary data. A channel selection device chooses the best transmission level as a function of the energy received over several transmission channels. The transmitted data are modulated using a frequency selected from several frequencies which define the transmission channels. The selection device produces a device configuration signal which is used for demodulation of a signal received over the chosen channel. The selection device delivers all the modulation frequencies to the modulator and delivers a single frequency associated with the selected channel for communication. This frequency is delivered to the demodulator and forms the configuration signal for the demodulator.

Abstract: A fuzzy logic control circuit is employed to vary the rate of refrigerant liquid injection for cooling the motor (20) of an air conditioning compressor (10). Control is based on the temperature of the motor and another measurable operating condition. The temperature deviations are grouped, rather than treated proportionately or gradually. The controller response to a given temperature deviation depends on the other operating condition. In a preferred mode, the other operating condition is the rate that the motor is heating up or cooling down. In a preferred embodiment, the control circuit determines the duty cycle for the solenoid valve (44) according to a matrix of five columns by five rows. This control scheme maintains the motor temperature within about 25°F of setpoint over a wide range of load conditions.

Therefore, when a deviation of the pressure pulse wave/blood pressure relationship is not significant, the execution of unnecessary sphygmomanometry for redetermining the pressure pulse wave/blood pressure relationship can be dispensed with, thus reducing the frequency of sphygmomanometry using a cuff, which in turn reduces the burden on the living body.

Abstract: A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix [k] is then calculated based on the relationship {f}=[k] {x}. Material property coefficients are then extracted from the material property matrix [k] for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.
