Abstract: A method of producing a polyether polyol includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, and the low molecular weight initiator has a nominal hydroxyl functionality of at least 2. The one or more monomers includes at least one selected from propylene oxide and butylene oxide. The polymerization catalyst is a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1, whereas M is boron, aluminum, indium, bismuth or erbium, R1, R2, R3, and R4 are each independent, R1 includes a fluoroalkyl-substituted phenyl group, R2 incudes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, R3 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3.

Abstract: A system and method for conformal alignment of an aircraft-based head worn display (HWD) system defines far-field features in view of the HWD display, each far-field feature having a 3D truth position in a navigational reference frame. The aircraft GPS/IRS determines pointing vectors to each feature in the aircraft reference frame. The HWD user estimates a nominal head pose for orienting the far-field features in the HWD display, and the HWD system renders the far-field features based on the nominal head pose and pointing vectors. The rendered far-field features are aligned to their real-world 3D truth positions (either manually or with the assistance of witness cameras) and a latched pose of the HWD headtracker system determined based on a successful alignment within accuracy bounds. Based on the latched headtracker pose, the HWD headtracker alignment and the alignment of the HWD display reference frame to the aircraft reference frame are updated.

Abstract: A tray is provided for the shipping and display of a row of articles, the tray when configured for shipping being adapted to receive a particular number of such objects and when configured for display being adapted to receive a different number of such objects, the difference in configuration involving an end portion of the tray which is movable between a first position constituting an elongation of the main portion of the tray and a second position closing an end of that main portion.

Abstract: New cobalt complexes of nitrogen mustard alkylating agents which have been found to have hypoxia-selective antitumour properties and are thereby useful antitumour agents are described.

Abstract: Preformed plastic chimney flashing includes a horizontal plate embedded in the mortar between two courses of bricks, and a lip extending downward from the outside edge of the plate. The plate, which extends across the full width of a brick, has holes for adhesion of mortar on either side of the plate. The lip is intended to cover ordinary metal flashing, which inserts between the lip and the brick wall. The lip includes a ridge on the lower inside edge to help seal against weather. The plastic is colored, weatherproof, and flexible. The flashing is preformed into several shapes adapted to cover runs, steps, corners, and cap bricks. No forming is required, only cutting to length for allow for some overlap.

Abstract: A bidirectional communications link, termed a customization window, comprises a series of routines including functions, procedures and status flags implemented in software, interfaced between a machine control logic (MCL) operating to control the auxiliary functions of a computerized numerical control (CNC) system and a numerical control (NC) operating to control the multi-axis motions of the system whereby the MCL, implemented in software, can access the NC, also implemented in software, and control the system but only under conditions dictated by the NC and enforced by the routines of the customization window so that, for example, the integrity of the NC software will not be compromised by any of the MCL software which is of a user programmable type. Additionally, machine setup data and the availability of optional system control features are routed from the NC to the MCL through the customization window.
