Mo3677 MD91-42-PU HCFC BLOWN RIGID FOAMS WITH LOW THERMAL CONDUCTIVITY BACKGROUND OF THE INVENTION Rigid polyurethane foams having low thermal conductivity values are produced by reacting an organic polyisocyanate with an organic material having at least two isocyanate reactive hydrogen atoms and an OH value of from about 200 to about 650 in the presence of a blowing agent. The blowing agent is a ...

USE OF CAPPED SURFACTANTS FOR PRODUCTION OF RIGID POLYURETHANE FOAMS BLOWN WITH HYDROCHLOROFLUOROCARBONS Composition and process for production of rigid polyurethane and polyisocyanurate foam, and foam made from such composition and by such process. A composition for production of rigid polyurethane foam includes a) an organic compound containing at least 1.8 isocyanate-reactive groups per molecul...

A cold-polymerizable dental material is rendered opalescent by the addition of a small amount of microfine titanium dioxide. The material enhances the lifelike appearance of a dental restoration or appliance.

Knitting is carried out by a knitting needle having a hook (7) at the front end thereof and a flexible element (12) coupled to the rear end of the hooked needle e.g. by insertion through a through-hole in the latter. Initially a desired number of chain stitches (4) may be cast on the needle and the front end of the hooked needle is threaded through the chain stitches forming a succession of croche...

The invention concerns a method of protecting a surface of a carbonatic material from corrosion, the method comprising treatment of the material surface with an acidic cationic silica sol, the pH of the sol preferably being from about 4 to about 7. The invention also concerns a new silica sol useful for performing the method and a method of preparing the new silica sol. Further, the invention conc...

A digital data processing system with shared, distributed memory transfers data between corresponding data sets within memory. For example, such system can have a plurality of processing cells interconnected by a hierarchical network. Each of the processing cells can include a central processing unit and a memory element. The storage space within each memory is arranged in sets, each capable of ho...

A high security bolt lock is described having the ability to reencrypt the combination code for the lock each time a key is used and thus partially defeat the use of an unauthorized key. The lock may be operated by a temporary one time use key. The key for the lock carries a data storage means and battery to provide a date/time stamp and key identification for any key used. The key and lock may be...

A method for making a filler from automotive paint sludge is provided. Paint sludge containing water, solvent and uncured polymer resin is treated by removing a first portion of the water by mechanically drying the sludge to produce a concentrated sludge, and a second portion of the water is removed by treating the sludge with a chemical drying agent to produce a dried powder. Alternatively, the s...

The skew angle of a sheet (39) (e.g., business form or other document) is detected by providing two sensors (40, 40') spaced from each other a known distance along a straight line perpendicular to the direction (A) of conveyance of the sheet. If there is a skew, the distance travelled by the sheet leading edge (44) between sensings by the sensors is determined, and the skew angle calculated from i...

The formation of paper webs produced by papermaking headboxes having damaged or imperfectly-formed headbox lips can be improved by providing the headbox with an extended flexible divider sheet which extends beyond the slice opening and is positioned adjacent the defective headbox lip. The extended divider sheet so positioned substantially eliminates the adverse effects of the defective lip on the ...

A version-up method and system in a multiprocessor system provides functions that a processor to be made version-up investigates resources under control by itself before deciding any of the resources to be moved and/or duplicated, that the processor decides any of the processors to which the movement and/or the duplication of any of the resources is destined, that the resource is moved or duplicat...

The creel assembly to supply a number of yarns esp. for warping, has an air channel over each creel leg and on the same vertical plane with at least one outlet opening. Each creel leg has a protective wall behind and on a parallel plan to the bobbin levels. The air streams from the outlet openings pass between the bobbin levels and the wall to pass wholly from the wall against the bobbins. Pref. e...

The vehicle sidewall flap is moved out in front of the wall by a linkage when opening. The linkage comprises support and guide rods which are hinged to the vehicle and are interconnected at fixed distance from the flap at this end. The rods move freely relative the flap and a gear at the end of the support rod is directly engaged by the linkage movement with a rack fitted onto the flap. Another ge...

The multi-element pedal consists of a pedal lever (2) and a pedal plate (3) connected together by a film hinge (4). A supporting arrangement (5) is in the form of a full or partial ring between the pedal plate and the pedal lever. The central axis of this ring bearing coincides with the central axis of the film hinge. A ring is located on both sides of the hinge. ADVANTAGE - Live hinge is subjecte...

The use is described of both (i) ranitidine bismuth citrate and (ii) one or more Helicobacter pylori-inhibiting antibiotics in treating or preventing gastrointestinal disorders. Pharmaceutical compositions containing both (i) and (ii) and methods for the preparation of pharmaceutical compositions containing (i) and (ii) are also described.

Assembly to register the position of the edge (2) of surface piles on a moving fabric (1), where the pile thickness abruptly changes, has at least two light radiators (41, 42) over the fabric (1) on both sides of the pile edge (2). Each delivers a light bundle (7) to strike the fabric (1) at the pile edge zone, with a light bundle cross-section across the direction of material travel. The light bu...

A security system for a metal cabinet door comprises a latch adapted to be locked by a lock operating the latching members of the door.
