A safety device for a laser ray guide in which a laser ray-receiving element is installed on the input side of a lens of a laser ray guide including said lens, and troubles occurring in said laser ray guide can be detected by means of said laser ray-receiving element.

A web of gray cotton fibers is entangled by passing it under a series of low pressure liquid jets which are oscillated in a direction transverse to the direction of travel of the web. The entangled web is then subjected to a cotton bleaching step, and then dried, to produce a coherent nonwoven fabric that requires no resin binder.

Fine particulate expandable styrene polymers have coatings applied thereto by: (a) introducing the fine particulate expandable styrene polymers into a closed mixing vessel; (b) reducing the pressure in the mixing vessel below atmospheric; (c) preparing dispersions of the coating materials and heating the dispersions to about 30 DEG to 90 DEG C.; and (d) aspirating the heated dispersions of the c...

Targets (30) of readily saturable mangetic material and mounted on protected articles (14) are detected when taken through an interrogation zone (24) in which an alternating magnetic interrogation field is generated by transmitter antenna coils (42, 44). The target (30) is driven alternately into and out of saturation and it disturbs the alternating magnetic interrogation field in a manner so as t...

A working machine which is intended for demolishing and excavating work comprises a chassis, an upper part carried by said chassis and arranged for rotational movement relative thereto about a vertical axis, and an arm arrangement carried by the upper part and including a jib structure which is connected at one end thereof to the upper part and the other end of which carries, via an intermediate a...

Asbestos-free, fiber-reinforced, hydraulically setting compositions can be processed to fiber-reinforced shaped articles. The compositions are obtained by mixing fibers, hydraulic binders and water-soluble or water-emulsifiable polymers and by adding a metallic compound, particularly a metal salt or hydroxide. The composition can be processed in the equipment conventionally used in the asbestos ce...

A process for the prevention of the propagation of errors in a security processor having processing circuits which carry out arithmetic and logic operations on given operands, and detection devices for detecting single definite breakdowns occurring in these processing circuits in which single ambiguous breakdowns resulting in the weakening of a signal are detected by the detection of the single de...

An NMR radio-frequency coil is made up of a plurality of conductive segments evenly spaced about the peripheries and interconnecting a pair of conductive loop elements. Each conductive segment includes at least one reactive element which may include a variable capacitive or inductive element.

Macrolides having the structural formula (I): were Q is -CH2OH or -CHO; and esters and salts thereof, having useful activity against gram-positive bacteria and Mycoplasma species, and their preparation by cultivating Streptomyces fradiae NRRL 12170.

A novel antibiotic complex designated BBM-2478 is produced by fermentation of an actinomycete strain J907-21 (ATCC 39417). The complex may be separated chromatographically into two bioactive components designated BBM-2478A and BBM-2478B. The BBM-2478A component displays both antibacterial and antitumor activity while the BBM-2478B component has antibacterial activity.

The invention relates to a new anti-cancer chemical compound which has been called rooperol and certain derivatives thereof of the general formula in which A is chosen from the group including a phenyl group, a substituted phenyl group and -CH2-O-R5 where R5=H, an alkyl (C1-C5), aralkyl or acyl substituent; R1 and R2 are chosen from substituents including H for both or singly if one of ...

A material intended to form a joint between at least two bodies on the outside of their interface, at least one of the bodies being deformable, is characterized by the following features: (a) it is formed of a fluid mixture having a viscosity, measured at normal temperature, of from 0.3 Pa.s to 700 Pa.s; (b) a dry extract of the fluid mixture, measured at normal temperature and pressure, is from 2...

Apparatus and method for implanting a sizing disc into an open unshirred end of a shirred tubular casing wherein the sizing disc has a larger periphery than the unstretched inner periphery of the unshirred end of the casing.

An intraocular lens (2) with which the natural lens of the eye (1) is replaced in connection with, for example, a cataract operation. By using a bifocal intraocular lens which has advantageously two different focal distances (8, 9), two images are produced on the retina (3), one of the images being sharp at close distance (7, 7') and the other being sharp at long distance (6, 6'). The brain emphas...

Light-sensitive compounds are described which have the formula (I) wherein R1 and R2 denote H or alkyl, R3 and R4 denote H or 4,6-bis-trichloromethyl-s-triazin-2-yl, R5 and R6 denote H or halogen, alkyl, alkenyl or alkoxy, and Ar denotes a mononuclear to trinuclear aromatic group. These compounds are suitable as photoinitiators for free-radical polymerization or as photolytic acid donors...

The disclosure relates to a boom structure in an oil-spill-combatting system. A water craft (2) has booms extending to each side, and the ends of an oil collecting rope (4) are secured to the ends of the booms. Oil is recovered from the rope by running the rope (4) through an apparatus (3) which is situated at the aft of the craft (2). The rope is run first in one direction and then in the opposit...
