Absorption mat lead-acid batteries poorly dissipate heat from the internal components of the battery (10) due to the air gap (35, 37) which exists between the plates (20) and the inner wall of the container (12). Improved thermal management of the battery (10) is achieved by filling the air gap (35, 37), an insulating gap, with a thermally conductive gel (40), such as a gel formed of fumed silica ...

Polycrystalline diamond (2) has non-uniform impurity concentration along the direction of thickness. The diamond near the rake surface (4) has lower impurity concentration. The diamond near the fixation surface (5) has high impurity concentration. The diamond with higher impurity concentration near the fixation surface (5) alleviates a strong stress or absorbs an external shock. Owing to the highe...

The present invention concerns a bag for curing food which will he placed into the bag, said bag being made from a heat-resistant, foldable material, preferably from metal foil or paper or similar material coated with a metal film. Conventionally, simultaneous flavoring and curing of food is awkward. The interior of the bag (1) according to the invention contains material releasing flavoring gas, ...

A device for immobilizing the head to prevent further injuries such as neck injuries comprises left and right complimentary blocks. Each block has a skull supporting surface. The blocks contact the skull with the skull supporting surfaces diverging outwardly and upwardly to provide a wedging action to immobilize the skull against left and right movement as well as to position the height of the sku...

: Multilayer plastic pipe The aim is to provide a plastic pipe having improved resistance, inter alia, to methanol-containing fuels and improved mechanical properties. This is achieved by a multilayer plastic pipe comprising at least one outer layer based on polyamide and at least one layer of a linear, crystalline polyester modified by means of an isocyanate mixture. The invention enables plastic...

An apparatus for performing the printing by scanning a carriage having a plurality of print heads mounted in a predetermined direction relative to the printing medium, so that an image is formed to have a desired color tone and density without decreased throughput. Conversion data for reproducing the color tone and the scan range of the carriage are changed in accordance with the used heads among ...

A lead's position recognizing device including device for detecting positions of maximum points and minimum points on each outline of each region surrounded by adjacent leads or positions of a pair of corners on diagonal of each outline and a device for detecting the lead's position from intersecting point of a straight line connecting midpoints between said maximum point and minimum point taken a...

These pigments are characterised in that they comprise oriented, three-dimensionally crosslinked substances having a liquid-crystalline structure with a chiral phase and optionally further dyes and pigments, where the further dyes and pigments optionally present do not serve as support for the oriented, three-dimensionally crosslinked, liquid-crystalline substances with a chiral phase.

A spool holder having a carrier arm (7) can carry thread spools having cylindrical or conical cores (3). This arm has a contact surface (8) for the core (3) and at the distal end thereof, an angled surface (10). This angled surface diverges at the free end of the carrier arm 7. Carrier arm 7 also has a freely hanging lever(11, 13) hinged about its upper end. The lever has such a length that when t...
