A second general embodiment includes biodegradable polymer comprising polymerized lactic acid where the number of repeating lactic acid units n is an integer between 450...

The process is characterised in that cefodizim is brought into solution using 1.5 - 2.5 mol of an organic amine base in ethanol with a water content of 4 - 15%, and the disodium salt of cefodizim is crystallised out by the addition of a sodium donor.

A method for forming a coating film is here disclosed which comprises the steps of coating a member with a coating material containing a pigment for a thermosetting base coat, overcoating the coated member with a coating material for a thermosetting clear coat in a wet-on-wet coating manner, and then thermosetting the uncured coating films simultaneously; a binder component in the coating material...

An insulation panel comprises a mineral fiber board having a density between 8 and 28 pounds per square foot, the fibers having no organic binder thereon, and between 5 and 40 percent by weight of particulate material packed in the interstices of the board, and a gas-tight envelope encapsulating the board, the envelope being evacuated to a vacuum between 10-4 Torr and 10 Torr.

A microcode branch, to one of a number of possible control words (57) (sixteen control words are described), is based upon (1) the remaining operand length that is to be processed by a left to right instruction, and (2) by the byte alignment of the portion of the operand that currently resides in main storage interface registers. As a left to right instruction (52) is being executed, the operand's...

Home carbonation apparatus and a carbon dioxide supply vessel (2) are provided with inter-engageable connector parts (10,16). The part on the apparatus includes a hollow cylindrical male member (14) which has an external seal (18) and within which an axially movable valve actuating plunger (30) is positioned. The part on the vessel includes a female member (12) having a cylindrical internal surfac...

Disclosed herein is a spunbond-meltblown-fiber composite laminate and a process for making the same. A spunbonded mat is ultrasonically bonded to a meltblown web. The side of the meltblown web opposite the spunbond mat is extrusion coated with a continuous layer of polymeric material which adheres to the fibers of the meltblown web and forms a fluid impervious backing layer.

A light control window covering comprising a first relatively translucent sheet (50) material, second relatively translucent sheets (51) of material, disposed parallel to said first sheet, a plurality of strips (60) of relatively opaque material, each have edge portions, said strips having their edge portions adhesively bonded to said first sheet (50) and said second sheet (51), respectively, wher...

A process and apparatus for making expandable honeycomb structures suitable for use as window coverings. In one embodiment, folded tubular strips with adhesive lines are fed continuously through a cutter whi ch cuts them into predetermined lengths. The cut skips are then accelerated to a stacker for further processing before the next cut strip arrives. In another embodiment, webs of material are f...

A thermally driven gas resonance device comprises a resonance tube (3) which expands in cross-section along its length from one end to the other, a heat source (2) located at the one end of the resonance tube, and means (2, 4) to trigger oscillations in a gas in the resonance tube. The heat source (2) is preferably a pulsed heat source having a pulse repetition frequency corresponding to a resonan...

Method and apparatus for the continuous industrial production of tubular bodies in which coated or uncoated steel strip is formed to a slit tube and the opposite strip edges are longitudinally seam welded at high speed by a laser beam of high energy density under protective gas with or without supply of additive material, and after a preparation adapted to the narrow melt zone and bringing togethe...
