A procedure for creating an optical output signal (S') in which two optical signal parts (S1, S2) of different frequencies are created from an optical signal (S) of a fixed frequency (v o), whereby one of the optical signal parts (S1, S2) has a data signal (D) impressed and both optical signal parts (S1, S2) together form the optical output signal (S'), the optical signal (S) is fed to two branche...

A process is described for removing contaminants from thermally cracked waste oil, e.g. used motor oil. In the process the cracked waste oil is contacted with a solvent comprising methanol. The thermally cracked waste oil is then separated from the solvent whereby a substantial portion of the contaminants are removed into the solvent. Thereafter, the solvent is separated from the contaminants and ...

An absorbent article with a longitudinal direction and a transverse direction, at least one elastic member (14) being arranged with prestressing in the crotch area (8) of the article, extending essentially in the transverse direction of the article. The elastic member (14) is arranged between the liquid-permeable surface layer (2) of the article and its absorption body (4) on a first surface of th...

A powder coating hand-gun usable in an electrostatic coating method in which the powder coating hand-gun is instantaneously responsive to a change or variation in the coating environment during the coating operation without the operator's interrupting the coating operation, and a coating system incorporating the same are provided. The rearward section of a barrel portion 14 of a hand-gun 12 includ...

A method for performing intrastromal photorefractive keratectomy in the cornea of an eye, using a pulsed, laser beam to photodisrupt a portion of the cornea, includes the initial step of focusing the beam to a focal spot at a selected starting point in the stroma. The starting point is located at a predetermined distance behind the epithelium of the cornea. While focused on the starting point, the...

Low density collapsed absorbent foams materials that, upon contact with aqueous fluids, in particular urine, can expand and absorb these fluids. These low density foams typically have an expanded thickness from about 6 to about 10 times the thickness of the foams in their collapsed state. These low density foams are made by polymerizing high internal phase emulsions (HIPEs) where the volume to wei...

An apparatus for the sterilization of a medical device includes a multi-chambered compartment having at least a first and a second rigid chamber therein. Each of the first and second chambers is adapted to independently serve as a sterilization chamber and can be operated independently. The apparatus also has a removable interface between the first and second chamber. The interface can have an ope...

Transdermal patches are disclosed, including a backing layer, a liner layer, and a monolithic adhesive and drug-containing layer between the backing layer and the liner layer. The drug-containing adhesive layer includes polyisobutylene, a plasticizer for the polyisobutylene in which the ratio of the plasticizer and the polyisobutylene is less than about 0.8 and at least 5% of a filler. The drug so...

The visual stimuli have a duration less than 1 second and the gap between two successive stimuli is no greater than 10 seconds in the absence of any response from the driver. In the event of the driver responding to a stimulus, the time gap between the successive stimuli depends on the driver's response time to the previous stimuli, the gap being shortened if the driver's attention is detected as ...

The grate bars are fixed to a rotatable horizontal cylinder, allowing the grate angle to be varied, and a moving scraper above the grate is used to keep the grate clear from blockages. - Solid biofuel (4) is burnt on a grate which is mounted on a horizontal cylinder (9), and the position of this cylinder can be altered by means of adjustment screws (12) in order to the change the angle of the grat...

Rail sections have interlocking L-shaped end regions, each formed by a long protruding finger. Two rail sections (1,2) are joined together in a line using a joint (3) formed by two opposing protruding rail section end parts (1a,2a) extending in the rail length direction. The end surfaces (1c,2c) of these protruding parts extend at right angles to the main joint-forming surfaces at the ends of the...

The drinking glass provides an observer with an impression of double vision and comprises a base with side walls which limit the container for a drink. The side walls are formed to limit two containers with intersecting side walls (15a,15b,25a,25b) and the intersecting side walls limit three separate volumes (31,32,33). Channels (34,35) are arranged in the base (30) to set parts of the separate v...

The invention relates to calcitonins and calcitonin derivatives such as are empl oyed for the therapy, for example, of osteoporosis, of Paget's disease or of hypercal cemia. The calcitonins and calcitonin derivatives according to the invention are distin guished by a bridging of the amino acids present in the positions 17 and 21. In this cas e, by means of suitable choice of the amino acids presen...
