A system and method of providing electrostatic pick-up of yarn on a rotating carrier tube or the like involving provision and use of an electrostatic generator for the application of a static charge to the leading section of the yarn which is subsequently directed across a spindle mounted rotating carrier in a manner whereby the yarn is adhered to or picked up on the tube by electrostatic attracti...

A release binding has a swivel element mounted on a base plate and a support member supported on the swivel element for pivotal movement about a vertical axis. A housing with a sole holder is pivotally supported on the support member by a horizontal axle. A notch carrier is supported for reciprocal horizontal movement in the support member and has a sector-shaped notch with a curved recess at the ...

PURPOSE:To release automatically a system deadlock, by deciding the deadlock when a communication buffer is filled for a fixed time or longer. CONSTITUTION:A counter monitor part 4 always monitors the value of a transmitting buffer counter SBC0. When the counter SBC0 shows the value obtained when a buffer is filled, a set signal is transmitted to a timer part 5. While a reset signal is sent to the...

The invention relates to polyurethane coatings prepared from the reaction products of a polyester or polyether, a hydroxyl compound containing acetylenic unsaturation and an organic polyisocyanate.

A step-in side-clamp safety ski release system is described, comprising an overcenter mechanism. In the overcenter mechanism there is provided a lever member (50). The lever member (50) is pivotably coupled intermediate its ends to a connecting member (40). When the lever member (50) is pivoted in a first direction, the member slidably engages a housing (1) for moving the lever member (50) and con...

A STEP-IN SKI BINDING A step-in ski binding with a laterally movable side-clamping member, a step-in member coupled to the side-clamping member, a force unit for providing a clamping force and connecting members for moving the movable side-clamping member from its open position to its closed position as the step-in member is moved from a clamp-opened position to a clamp-closed position and for app...

A safety ski binding part includes a base plate having a cam member supported thereon, a sole holder supported on the base plate for pivotal movement around a vertical axis and a transverse horizontal axis, the sole holder having a shoulder thereon. A lever supported on the base plate for pivotal movement about a transverse axis has a nose engageable with the shoulder. A transversely extending cam...

A method and an apparatus for testing the tightness of a threaded connection between an oilfield pipe and a tapped connector. An annular space along the threaded connection is sealed with a test head, and only the threaded connection is thus subjected to internal hydraulic pressure via this connection.

Disclosure is made of a method of curing the polyepoxide resin binder component of polyepoxide based syntactic foams. Ketones are employed to reversably block primary amine groups on polyamine curing agents during the initial curing. As the cure progresses, the block is removed to complete the cure. The result is a moderation of peak exotherms generally associated with the cure, inhibiting degrada...

In a constant amount control for a mechanism having hydrostatic drive (15, 16), an electro-hydraulic linear actuating drive (5) is provided as a servo mechanism for the drive diesel motor (13) and an electro-hydraulic servo mechanism (6) is provided for the variable displacement pump (15), which are controlled by a movable control board (1). According to a further measure, a closed hydraulic circu...

PURPOSE:To prevent diffusion and precipitation to wiring and connecting materials from electrode materials and also prevent poor connection by removing only the electrode material after providing an alloy layer of semiconductor and electrode material by thermal processing. CONSTITUTION:An N-epitaxial layer 2 is laminated on an N type InP 1 and a InGaAsP3 and a P type InP 4 are also formed epitaxia...

A coating composition for polypropylene resins is disclosed principally comprising a chlorinated polyolefin (I) obtained by chlorinating, to a degree within a range from 10 to 50 wt%, a polyolefin which is modified with one or two or more kinds of compounds selected from unsaturated polybasic carboxylic acids and their acid anhydrides and is of a saponification value between 6 and 60; and a compou...

18. This invention is directed toward a rubber skim stock composition and a product containing the skim stock having improved adhesion and adhesion retention with metallic reinforcement cords such as brassed steel. The invention composition comprises a vulcanizable rubber skim stock and an organic salt of cobalt and an organic salt of nickel and is prepared by mixing the cobalt and nickel salts wi...

A SLAG OUTLET FOR A GASIFICATION GENERATOR (D#76,726-F) Structure for slag removal from a gasification generator. It employs a duct through the bottom that carries through it products of the combustion which is being carried out in the generator. The dimensions are such that the slag which adheres to the walls remains liquid and drips from the bottom edges. The duct is enlarged by at least one ste...

METHOD OF ETCHING POLYIMIDE In etching openings in polyimide film, the film is first etched with a basic reagent in its uncured or partially cured state to form the desired openings, and thereafter, the film is cured. However, this will leave a layer of disturbed material surrounding the openings which has absorbed some reagent and will not fully cure and, therefore, not provide topography suitabl...

A well testing tool system for isolating vertically spaced portions of a well bore and measuring well conditions such as pressure, and temperature. The system includes a wireline supported tool train and a locking sub connectible on a removable lock mandrel for releasably locking the tool train in a well bore. The tool train has a locking probe releasably connectible in the locking sub, a probe ma...

The invention relates to a nonwoven fabric having a valuable combination of properties that makes the fabric particularly useful as a wiping cloth.
