In a system for controlling a machine tool by a tool controller under the supervision of a central data processor, in which the controller transforms the data provided by the central processor into a format compatible with the machine tool, e.g., clock pulse encoded data format suitable for writing into and reading out of a serial storage magnetic memory device, a test system is provided wherein t...

A method indexed indirect addresung is provided with matched pairs of prefix bvtes (PR) and suffix values (IM1, IM2) which can surround any instruction. The method consists in fetching a prefix code (PR) in the instruction stream, fetching a word in main memory at an address specified by the contents of an index register modified in accordance with a suffix value (IM0), and interpreting this word ...

A method of producing blocks of self-adhesive labels or the like comprises feeding continuously to a cutting device (12, 13; 33, 34) a continuous label stock (10; 30) which on one face has a number of repeated images (11; 31) overlaid by a release coating and on the other face has a pressure-sensitive adhesive coating (16; 32). In the cutting device a succession of sheets (20, 37), each having mor...

A mechanism and method for locking or securing a bearing insert to the base of a prosthetic implant. The prosthetic implant is for replacement of a portion of natural bone at a point of articulation. The implant includes a locking mechanism which enables the bearing insert to be removably secured to the base support. The locking mechanism includes a resilient locking clip which is predisposed on o...

An acidic polycyclic ether antibiotic, having structure established by X-ray crystallography, is formed by fermentation of a novel microorganism, Actinomadura sp. ATCC 53676. This novel antibiotic is useful as an anticoccidial in chickens and as a growth promotant in cattle and swine. h

There are disclosed anti-tumor prodrug compounds that are (a) disulfide benzylcarbamate derivatives of amino (primary and secondary) containing anti-tumor drugs, and (b) disulfide benzylcarbonate derivatives of hydroxyl containing anti-tumor drugs. The prodrug compounds release active, free drug as a result of undergoing reductive cleavage of the disulfide moiety and subsequent chemical fragmentat...

A microbubble-type ultrasonic imaging agent is provided comprising a parenterally-administerable aqueous medium containing a dispersion of microspheres predominantly of diameters less than 10 microns, wherein the microspheres consist of gas microbubbles encapsulated with water-insolubilized biocompatible material. The imaging agent is characterized by having a concentration of greater than 100 x 1...

New cytostatically active anthracycline derivatives are described which correspond to the following general formula I in which the radicals have the following meaning: R<1> is a C1-4-alkyl group; R<2> is a hydrogen atom, a tri-C1-4-alkylsilyl protecting group, an acetyl, monohalo-, dihalo- or trihaloacetyl group where halogen equals fluorine or chlorine, or a benzoyl or p-nitrobenzoyl gr...

K 5380 Process for the preparation of atmospheric hydrocarbon oil distillate(s). A vacuum residue is catalytically hydrotreated. The hydrotreated product is separated by distillation into atmospheric distillate(s) and a residue. At least part of the residue is separated by deasphalting into a deasphalted oil and asphalt. The deasphalted oil is catalytically caracked to one or more atmospheric dist...

An ultrasound sensing apparatus suitable for human body scanning, particularly regions which are difficult to scan with larger ultrasound heads. The ultrasound transducers are mounted for rotation in an off-axis configuration. With this configuration, transmission and reception of sound occurs without the sound being normal to the membrane contacting the body. This eliminates reverberation problem...
