Abstract: A method of assessing radar pulses in a passive, i.e. receive-only, radar system to distinguish pulses due to a particular target from pulses due to other targets from noise, interference, etc. Received pulses are assessed, without reference to pulse transmission information, in respect of a number of characteristics by comparing each characteristic of a pulse with the mean value of the respective characteristic for pulses previously received. Using a probability process, confidence values for the pulse can be calculated. By combining the confidence values for each characteristic, an overall confidence value is obtained for the pulse so that it can be determined whether it arises from the particular target.

Abstract: An optical fiber arrangement providing uniform illumination of a region in a plane beyond the end of an optical fiber and normal to the fiber axis. An array (12) of four prisms (A,B,C,D) is disposed adjacent to, but spaced from, an end (11) of an optical fiber (5). By appropriate choice of the prism angle (.theta.) and its spacing (d) from the fiber (5), the prism array (12) modifies the angular distribution of light from the fiber (5) in two ways. The shape of the illuminated region is changed from circular to square and the illumination becomes substantially constant over the square region. In an assembly of fibers, each modified in this way, the amount of overlap needed between the outputs of neighbouring fibers can thus be reduced and a more uniform light output can be achieved. Other non-circular regions of illumination, for example of pentagonal and hexagonal shape, can be produced using different optical components and the same benefits obtained.

Abstract: The material similarity of all-silica waveguides or other devices and optical fibers is utilized to establish an epoxy-free fusion interfacing between optical fibers and integrated-optic devices by using laser welding techniques. This is uniquely applicable to all-silica integrated devices since they have virtually identical material properties to those of optical fibers. The method comprises the steps of machining a locating groove in a silica block, fixing a prepared length of the optical fiber in the locating groove, bringing the block and the device into juxtaposition and aligning the block and the device to provide maximum transmission of a signal from the fiber to the device and laser welding the block and the device together.

Abstract: The therapeutic use of new salts of physostigmine in the treatment of syndromes related to changes in cerebral metabolism in the elderly is described. The new salts of physostigmine, which are based on phosphatidic acid, are highly lipophilic and exhibit excellent bioavailability when administered orally, transcutaneously or transepidermally.

Abstract: A novel method of treating fibrotic disorders in humans comprises the administration of a sufficient quantity of a composition containing a human alpha- or beta-interferon to raise the total concentration of such interferon in the affected tissue area to about 10 to about 4.times.10.sup.7 IU per cubic centimeter. The interferons used can be naturally derived or recombinant DNA-derived. The interferon composition can be administered by any indicated conventional method and can include any pharmaceutically acceptable, interferon-compatible vehicle.

Abstract: An optical device comprising a length of optical waveguide (1) having incorporated therein an extended sequence of coupled single resonator structures (9) so as to form an optical slow wave structure. The sequence of resonator structures is suitably formed by a Bragg diffraction grating pattern (7) extending along the waveguide.

Abstract: A process is provided for the purification of L-asparaginase by contacting a crude extract of L-asparaginase with a solid medium having cation exchange groups so as to adsorb L-asparaginase on the support and eluting adsorbed L-asparaginase from the support. The cation exchange groups comprise sulphonate groups and the elution step is carried out at a pH which is higher than the pH used in the contacting step.

Abstract: According to the invention, there is provided a machine for treating raw meat, which comprises an injecting apparatus and a plurality of massaging apparatuses. The injecting apparatus includes injecting needle means adapted to be thrust into raw meat for injecting a pickle solution, and an outlet end from which the raw meat is discharged after injecting the pickle solution thereinto. The massaging apparatuses each includes a container adapted to be charged with the raw meat having the pickle solution injected thereinto for massaging, mixing and salting the same, and an inlet end adapted to receive the raw meat and direct the same into the container. The massaging apparatuses extend longitudinally of the injecting apparatus at a position downstream of the injecting apparatus, the massaging apparatuses being arranged side by side widthwise thereof.
