An automatic umbrella includes a central post, a canopy assembly, and a spring and linkage mechanism which causes the umbrella to open when desired. There is also commonly a feature used for securing the umbrella in the closed position.

A tire building drum (10) has a plurality of expandable axially extending, circumferentially spaced-apart segments (18) with an elastic cover sleeve (48). The radius (C) of the radially inner surface (50) of the cover sleeve (48) is greater than the radius (B) of the radially outer surface (20) of the segments (18) in the contracted condition of the drum (10) for placing the cover sleeve (48) over...

A urethane prepolymer composition is provided comprising (a) a terminal isocyanate group-containing urethane prepolymer derived from a polytetramethylene glycol having a specific molecular weight of 700 to 1500 and an aliphatic and/or alicyclic diisocyanate and (b) a terminal isocyanate group-containing urethane prepolymer derived from a polycaprolactone diol and/or polyol having a specific molecu...

Apparatus for detecting line-over defects at the finish of a glassware container. A bifurcated fiber optic bundle (30) includes sender (31) and receiver (33) fiber branches; one of the branches terminates at a modulated visible red high intensity LED light source, the other at a photosensor. The non-bifurcated, probe end (46) of the fiber optic cable terminates in a rectangular pattern of sending ...

A method detects incomplete coverage of hermetic coatings applied to optical fibers during in-line optical fiber fabrication procedures as well as off-line applications. A fluorescent material surrounds the core region of the optical fiber prior to the formation of the hermetic coating on the optical fiber and energy is radiated in the optical fiber to propagate in the cladding mode. This causes a...

Inspection of a circuit board (10) to detect missing and misaligned active and passive surface-mounted components (12) and (14), respectively, is accomplished by first illuminating the board with top light to enhance the image of the passive components. The circuit board is then displaced, relative to a linescan camera (28) trained on the board, so that the camera captures the image of successive ...

A method for determining a sludge content in a heavy hydrocarbon oil and a device therefor are disclosed. The method comprises measuring absorbances of a heavy hydrocarbon oil sample, having an oil film thickness selected form a range of from about 0.01 to 5 mm, at two different wavelengths selected from the visible light region of from 500 to 1000 nm and determining a sludge content of the sample...

A transportable data system includes two units (3, 4) which are fitted in a rigid case which includes a lid (2) and a bottom part. When the lid is closed, the one unit (3), which is supported by a carrier plate, is located above the other unit (4), whereas when the case is open, with the lid substantially vertical, the one unit can be moved towards and partially into the lid, so as expose the othe...

An improved method is provided for producing mechanically alloyed powders on a commercial scale comprising milling the components of the powder product in a gravity-dependent-type ball mill to produce a powder having a characteristic apparent density. Powder so produced will have reached an acceptable processing level and will meet one criterion for determining whether it will be suitable for furt...

Use of Laser to Break Down Objects For Removal From Within The Body Calculi, stones, calcified tissue and other material are broken down for removal from within a body using laser pulses that are delivered via an optical fiber and have a wavelength, intensity, energy per pulse and pulse duration selected to break down the object into smaller particles without delivering energy sufficient to cause ...

PCT No. PCT/DK88/00120 Sec. 371 Date Jan. 16, 1990 Sec. 102(e) Date Jan. 16, 1990 PCT Filed Jul. 14, 1988 PCT Pub. No. WO89/00594 PCT Pub. Date Jan. 26, 1989.It is well known that the use of the blowing agent monofluortrichlormethane, also called Freon 11 or R-11, for the production of polyurethane foam is highly disadvantageous in that R-11 has a decomposing effect on the ozone layer around our p...

Composite breathable film comprising a breathable polyolefin film heat laminated to a nonwoven HDPE fabric. Preferably, the breathable film is prepared by melt embossing a highly filled polyolefin film to impose a pattern of different film thickness therein, and stretching the embossed film. The nonwoven fabric is made by cross-laminating HDPE fibers at the crossing points to form a thin open mesh...

The present invention is directed to non-porous isocyanurate-crosslinked polyurethane membranes. These membranes are useful for the separation of aromatic hydrocarbons from non-aromatic hydrocarbons.
