Title: Ac-dc converter type of supply
Inventor: HUILLET HENRI
IPC: G05F1/70
Filed: 1990-12-07
Granted: 2000-02-01
Abstract: Disclosed is a supply of the AC-DC converter type where the regulation is achieved by successive operations for charging and discharging a capacitor.      The supply includes an input oscillator circuit, the period of which is very small as compared with that of the input AC voltage. A first switch is closed during the time necessary for the charging of the capacitor of the oscillator circuit. When it opens, a second switch gets closed to enable the transfer of energy towards the load. The regulation is done by an oscillator circuit which is controlled by an error voltage on the load and which triggers a monostable trigger circuit to close the first switch and open the second one during the period when this monostable trigger circuit is in its quasi-stable state.

Title: Electrostatic relay
Inventor: SAKAI JUN
IPC: H01H59/00
Filed: 1992-06-23
Granted: 1997-11-11
Abstract: An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported to a pivot so as to have a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts.  A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces of attracting and repelling the movable electrode plate, respectively when the movable electrode plate is charged to a given polarity.  That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plates in one direction from one of the rest positions to the other.  The electrostatic relay is useful for precisely and rapidly operating of the relay.

Abstract: A distinctive apparatus and method for selectively providing predetermined segments of web material comprises a supplying mechanism for providing the web material. A first sensing mechanism detects a reference marker on the web material to generate at least one reference marker datum which is associated with a selected web segment. A separating mechanism includes a sensor mechanism for providing at least one separation datum, and divides the web material along a separation region during a production of the web segment. A phase regulating mechanism controls a relative phasing between the reference marker detected by the first sensing mechanism and the dividing by the separating mechanism. The phasing is conducted with respect to a set reference value. An assembling mechanism places the web segment onto a substrate, and a second sensing mechanism separately detects a location of the separation region relative to the reference marker to generate at least one location datum which is in correspondence with the separation datum. A location correlating mechanism generates at least one comparison datum associated with a web segment, and a data processing mechanism evaluates the comparison datum to generate an updated set reference value. A reference regulating mechanism selectively adjusts the phase regulating mechanism to incorporate the updated set reference value.

Title: Highly regular multi-arm star polymers
Inventor: ZHOU LIN-LIN
IPC: C08G81/02
Filed: 1992-08-14
Granted: 2001-05-29
Abstract: A carbosilane-based hybrid star polymer having a carbosilane core of large size and addition polymer chains emanating from the core, is described. The carbosilane core is formed from a central silane nucleus and built up by repeated alternating hydrosilylation of reactive vinylic sites followed by vinylation of silicon halide reactive sites. The core is reacted with living addition prepolymers to form the hybrid star polymer. The minimum core size to give the desired properties corresponds to that having at least about 48 reactive silicon halide sites on the periphery. These highly regular hybrid star polymers have unique solution and gelling agent properties and form highly structured and rigid gels, and also act as viscosity modifiers. The large carbosilane core having either vinyl or silicon halide reactive sites can be used as a reactive intermediate.

Abstract: A thermosyphon for removing heat from a permafrost foundation is compared of a sealed container containing an easily vaporizable liquid. The container has a condenser part, which is exposed to temperatures below the condensation temperature of the liquid, and an evaporator part in which the liquid is intended to boil. The evaporator part is of double-tube structure with a supply tube and a return tube connected to each other at a paint distal from the condenser part. The return tube has a riser with an opening at one end which is inside the supply tube and has a much smaller cross-sectional area than the supply tube around it. The tubes may have both rising and falling sections but the opening of the riser is sufficiently higher than these sections of the tubes such that the hydrostatic pressure causes the liquid in the evaporator part to flow from the supply tube into the return tube as the liquid forms bubbles in the evaporator part and overflows from the riser opening.

Abstract: A method and apparatus for producing blood component products.  In  one  embodiment,   a  plurality  of  a predetermined type of blood component is harvested from a source  of  whole  blood.    At  least  two  on-line  yield determination techniques are utilized to determine the yield  of  the  harvested  blood  components.    One  is  a predetermined yield prediction technique and the second is a predetermined yield monitoring technique, each of which are individually calibrated in relation to a predetermined off-line yield determination technique.  The predetermined yield prediction and monitoring techniques each provide the yield of the harvested blood components and each is then utilized to provide a determined yield.  Consequently, when the harvested blood components are packaged the determined yield may be associated therewith,  thereby providing a blood component product.
