For the purpose of lubricating a cavity, particularly an annular cavity in a tool for forging blanks produced by powder metallurgy, a lubricant spray is directed towards a limited portion of the cavity surface and the nozzle is displaced such that impingement area of the spray against the cavity sweeps over the entire surface of the cavity. The impingement surface of the lubricant spray is adapted...

A multi-purpose tracheal tube for use with high frequency ventilation. The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient....

The heel support of a ski binding has a sole support which can be pivoted about a horizontal transverse axis and has a closure pedal. In the position of use, a locking member engages behind a part which is movably mounted in the sole support and is locked by an element capable of pivoting with the latter. Provided on the sole support is a handle for the arbitrary opening of the heel support which ...

A disk brake, preferably for use in connection with industrial machinery, has a pair of braking levers which carry at one end brake shoes located on opposite sides of the disk.

A coating composition for glass fibres intended for use as reinforcement in cementitious products is disclosed, which contains at least one monocyclic or polycyclic aromatic compound having at least three hydroxyl groups on the aromatic ring or (in a polycyclic compound) on at least one of the aromatic rings, together with at least one partially-cured A-stage phenolformaldehyde resin of the water-...

A process for promoting the adhesion of polyolefins to a substrate comprising admixing an olefin polymer with t-butyl beta-hydroxyethyl peroxide, applying the resulting polyolefin to a substrate surface and applying heat and pressure thereto to affect adhesion of the polyolefin to said surface.

Starch products which were hitherto used as pore-forming substances in the manufacture of polyvinyl alcohol acetal sponges are replaced by polyethylene glycol or polyacrylamide. This results in a more uniform distribution of pore size, lower shrinkage of the sponge material during the acetalization, and easier washing of the sponge after the acetalization.

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 suitable for reliable interconnecti...

PURPOSE:To make the easy and accurate setting of conditions of insert patterns with simple constitution by controlling monitor images by the use of an offlined image pickup system. CONSTITUTION:The video information from an image pickup system by a TV camera 2 and a processing circuit 3 for image pickup signals is stored in the memory of an image simulation device 4. Main patterns are monitored by...

Dental methods and materials are disclosed for treating diseased or traumatized teeth and peridontal tissues. Physiologically compatible and soluble calcium phosphate compounds are prepared into a porous aggregate paste or powder and positioned adjacent to calcified tissue in contact with a blood supply. Such a technique permits improved methods for pulp capping procedures, root canal procedures, ...

Positioning apparatus for vertically moving a scanning assembly includes a vertical support, a first arm pivotally attached to the support and to the scanning assembly, and a second arm pivotally attached to the support and to the scanning assembly with the first and second arms being parallel. A counter-balance is provided and is attached to the support by third and fourth arms which are pivotall...

PURPOSE:To prevent the increase of access time due to enlargement of inter- wiring capacitances by protecting a device from the radiant ray such as the alpha particles emitted from the package material used for a semiconductor device with the resin such as a polyimide and by covering a part of the semiconductor element surface in order to establish isolation. CONSTITUTION:The polyimide resin 1 use...

PURPOSE:To prevent wire disconnection and to form the alpha rays shielding film which can be sealed with resin by providing the dam around the alpha ray shielding film forming region so that the bonding resin for alpha ray shielding film does not flow into a bonding pad and by forming the alpha ray shielding resin with bonding method. CONSTITUTION:The varnish of polyimide precursor is coated on th...

Hydrophilic biopolymeric copolyelectrolytes are prepared from (a) a water-soluble linear anionic protein polyelectrolyte component derived from keratin, such as ammonium keratinate, and (b) a water-soluble linear cationic biopolymer polyelectrolyte component derived from a glucosaminoglycan and/or collagen, such as chitosan acetate and/or collagen acetate. Hydrogel membranes formed from the copoly...

PURPOSE:To enhance the heat resistance and dimensional stability of a semiconductor device package formed with a thermosetting resin by sealing inactive gas within the space formed by semiconductor element and thermosetting resin on the upper part of the semiconductor element and by forming a low melting point glass thin film at the interface between this space and the thermosetting resin. CONSTIT...

A new acidic polycyclic ether antibiotic has the formula: +TR and can be prepared by the submerged aerobic propagation in aqueous nutrient media of Streptomyces halstedii ATCC 31812. The antibiotic and its cationic salts are active against a variety of microorganisms and are effective in controlling coccidiosis, enteritis, swine dysentery and theileriosis as well as being effecti...

New S-adenosylmethionine (SAM) salts of formula (I) have been prepared in which R, R1, R2, m, n and A are as defined in the text.
