Abstract: A baulkring-type synchronizer (18) includes cone clutch friction surfaces (24,48 and 26,50) and jaw clutch teeth (36b,28 and 36c,30) for frictionally synchronizing and positive connecting gears (14,16) to a shaft (12). A torque ring (63) is mounted in a shift sleeve (34) for limited rotation relative thereto and non-axial movement relative thereto. The ring defines self-energizing ramp surfaces (74a,74b,74c,74d), blocker surfaces (76a,76b,78a,78b), and reaction surfaces (76c,78c). The ring self-energizing ramp surfaces engage self-energizing ramp surfaces (70a,70b,72a,72b) defined on an outer circumference of a hub (32) affixed to the shaft. The ring blocker surfaces engage blocker surfaces (44a,44b,46a,46b) affixed to baulkrings (40,42). The ring reaction surfaces engage reaction surfaces (44c,44d,46c,46d) affixed to the baulkrings. Synchronizing torque produced by friction surfaces is partly reacted across the blocker surface, the remainder is reacted across the reaction surfaces, and the sum of the total synchronizing torque is reacted across the self-energizing ramp surfaces. A shift sleeve (34) is slidably splined to the hub (32) and is moved by an operator shift force (F<sub>o</sub>) and an additive force (F<sub>a</sub>) provided by the self-energizing ramp surfaces. Both forces (F<sub>o</sub> and F<sub>a</sub>) react against the blocker teeth to engage the friction surfaces.

Title: Method and apparatus for treating an ophthalmic lens mold
Inventor: ADAMS JONATHAN P
IPC: B29C71/04
Filed: 1994-12-23
Abstract: An apparatus and method for causing the polymerized excess  monomer  to  separate  from  a  molded  lens  by increasing the surface energy of the flange area of one mold piece,  causing the polymerized excess monomer to stick thereto.  Specifically when manufactured under inert atmosphere conditions, a particular manifold is needed to supply an oxygen bearing gas, air,  to the area to be treated while preventing the oxygen from contaminating the lens manufacturing area of the molds or diluting the nitrogen atmosphere of other lens process areas.  It has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated.  In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

Title: Policing method
Inventor: WITTERS JOHAN H
IPC: H04L12/56
Filed: 1995-02-01
Abstract: A policing method is proposed policing an aggregate ATM cell stream (IN) consisting of both high and low priority cells. The method consists in policing the aggreqated stream as a whole whilst also policing separately a substream formed by the high priority cells as prescribed by ITU-TS recommen-dation I.371.          The present policing method always inserts a high priority cell satisfying the last mentioned separate policing step into the output stream (OUT) regardless of the result of the first mentioned aggregate policing step. In order to keep a good performance for the method, the predicted arrival time used in this aggregate policing step is however also updated for such a high priority cell which does not conform to this aggregate policing step. The latter requires a modification of the known and commonly used Virtual Scheduling Algorithm.

Filed: 1995-10-24
Abstract: An article having a durable non-wetting surface is disclosed wherein a plastic substrate surface is first treated by deposition of a silica primer layer.  The plastic substrate surface bearing the silica primer layer is then treated with a composition comprising a perfluoroalkylalkylsilane and, optionally, a fluorinated olefin-telomer.  The perfluoroalkylalkylsilane provides the non-wetting surface property, while the silica primer layer provides durability to the non-wetting surface property.  A method of producing a durable non-wetting surface on a plastic surface is also disclosed, comprising depositing a silica primer layer on a surface of the plastic substrate, and then contacting the silica primer layer with a perfluoroalkylalkylsilane composition.  The silica primer layer is preferably deposited by applying to the plastic substrate surface a solution of a hydrolyzable silicon-containing compound, such as tetrachlorosilane, which hydrolyzes and condenses to form a silica-containing film.

Title: Transmit power level detection circuit with enhanced gain characteristics
Inventor: STRAKOVSKY LEONID
IPC: H03G3/30
Filed: 1996-02-29
Abstract: A circuit for maintaining the magnitude of a radio frequency (RF) signal at least one predetermined level employs a detection circuit (16) coupled to an RF signalgenerator (22) by a four port coupling device (12). In one embodiment of the present invention, an impedance inverter (30) in series with a diode (D3) is connected between the load termination (L) of the coupling device (12) and ground. The series combination of the impedance inverter and diode approximates a short circuit as the output signal power approaches a predetermined low amplitude threshold and approximates an open circuit as the output signal power approaches a predetermined upper amplitude threshold so that gain is provided to signals received by the detection circuit below a first amplitude level and attenuation is provided to signals received by the detection circuit above a second amplitude level. The transmit level detection circuit of the present invention requires substantially less power than conventional circuits, so that only 1%-2% or less of the output of the amplifier need be diverted for reliable operation, even for RF output power levels on the order of a fraction of a milliwatt.

Title: Thermal apparatus and process for removing contaminants from oil
Inventor: TACIUK WILLIAM
IPC: C10G9/16
Filed: 1996-09-27
Abstract: Used oil is treated in a reactor to remove contaminants. The reactor comprises a rotating vessel forming an internal reaction chamber. The vessel is housed within a heating chamber. The inside of the vessel is indirectly heated by conduction through the vessel walls. The reaction chamber contains a permanently resident charge of non-ablating, granular coarse solids. Within the reaction chamber, the oil is vaporized and pyrolyzed, producing a hydrocarbon vapour. Coke is formed as a byproduct. Contaminants, such as metals and halides become associated with the coke. The coarse solids scour and comminute the coke to form fine solids. The fine solids are separated within the reaction chamber from the coarse solids and are removed from the vessel through a pipe located at the axis of the vessel. The hydrocarbon vapours are also removed from the vessel through the axial pipe, as a separate stream. Residual fine solids are separated in a cyclone from the vapour stream. The cleaned vapour stream is then condensed to produce a substantially contaminant free product oil. The contaminant-rich solids are collected for disposal.
