Abstract: A semiconductor laser in which a light emitting region (A) having a light emitting layer (3,4) and a waveguide region (B,C) having a waveguide layer (6,7) which is coupled to at least one side of the light emitting layer with a high efficiency, are integrated on the same substrate. The light emitting region includes an active filter section (A₂) having a diffraction grating (5) equipped with a band-pass filter function. The light emitting region and the waveguide region are electrically isolated (14,15,16) and are each provided with an electrode (10,11,12,13). The oscillation wavelength of the semiconductor laser is changed by changing the refractive indices of at least the waveguide region and the active filter section through voltage application or current injection to the electrodes, thereby producing a narrow-linewidth, single-wavelength, oscillation output light of a wavelength which corresponds to the transmission wavelength of the active filter section determined by the preset refractive indices of the waveguide region and the active filter section.

Abstract: The thermal insulation material comprises a strip of felt made of mineral fibres (1) covered over its external face (2) by a virtually air- and vapour-tight protective sheet (3). The protective sheet (3) is made from a fire-resistant transparent or translucent polymeric material and extends on either side of the strip (1) so that the surplus lateral portions (4, 5) of protective sheet (3) act as an element for fixing the insulating material. Furthermore, the sheet (3) adheres to a central portion (6) of the external face (2) of the felt strip (1) so as to provide, over the said face (2), two longitudinal lateral zones (7, 8) free of any adherence. Such a material may advantageously be used for the thermal insulation of roofing, floors or walls. <IMAGE>

Abstract: The object of the invention is a method for the switching failure protected operation of switchgears of a substation. The topological construction of the substation and switching failure protection locking rules which are independent of the topological construction are stored. The present operating state of the substation is formed from the present position indication signals of the switchgears of the substation and the stored topological construction of the substation, and are processed to release or block switching operation requirement commands, by means of the stored switching failure protection locking rules. The initial and end nodes, the type of switchgears and the edge nodes are used as the basic set. By means of a switching operation requirement command for a switchgear, based on its initial and end nodes, tree developments are carried out by means of which electrically connected regions are determined, taking into account the state of the switchgears. The release or blocking of the switching operation requirement command is determined from the overall state of the region by comparison with switching failure protection locking rules. <IMAGE>

Abstract: A manufacturing method of a superconducting material having the steps of: milling and mixing a powderly primary material in a casing of a dry type milling mixer; heat-processing the primary material obtained from the milling/mixing step; and again milling and mixing the primary material obtained from the heat-processing step in the casing of the milling mixer so as to obtain a secondary material. The milling mixer includes a casing for holding the primary material therein and friction-pulverizing mixing elements for frictionally pulverizing, stirring and mixing the primary material inside the casing. The two milling/mixing steps are effected under a high-speed rotation of the casing where a centrifugal force resulting from the casing rotation presses the primary material against an inner surface of the casing and a layer of the material formed on the surface is frictionally pulverized, stirred and mixed by the friction-pulverzing mixing elements.

Abstract: The invention is concerned with treatment of gelatins, so as to remove or reduce off-flavours. It has been determined that the off flavour may be reduced by membrane filtration to remove a low-molecular weight fraction. 
     The invention provides gelatine substantially without a low molecular weight fraction and a process for the purification of gelatine which comprises removal of a low-molecular weight fraction by membrane filtration. 
     While it is difficult to be precise about the substances responsible for the off-flavour, it is believed that 4- and 5-methyl indane are removed by the filtration. Accordingly, a further aspect of the present invention provides gelatine substantially free of 4- or 5-methyl indane, and a gelatine preparable by membrane filtration under such conditions as to substantially remove 4- and 5-methyl indane. While it is not confirmed that the methyl indanes are the  per se  cause of the off flavour it is proposed that the off flavour promoting species are removed under conditions which also remove the methyl indanes.

Abstract: A flight path angle symbol is positioned on an aircraft attitude display indicator as a function of either a measured flight path angle or a flight path angle commanded by the pilot. When the aircraft is operating within a selected airspeed, angle of attack, pitch attitude or load factor range, or the difference between measured flight path angle and commanded flight path angle is within a selected range, the symbol is positioned on the display as a function of commanded flight path angle. However when the aircraft is operating outside any of these ranges, the symbol is positioned on the display as a function of the measured flight path angle. To avoid a rapid jump in symbol position when transitioning between measured and commanded flight path angle displays, a phase lag filter is used to attenuate and lag the symbol positioning signal.

Abstract: In a radio concentrator system, a master station and a terminal station cooperate with each to establish connections between remote subscriber terminals and a public switched network through radio message channels. An intraoffice call is set up between first and second subscriber (CT-1, CT-2) terminals through the connections (50,60,53,63) established in the terminals and master stations via the network. Upon establishment of such an intraoffice call, the terminal and master stations clear their connections (50,60,53,63) and reestablishes local connections (54,64,55,65) in the terminal station between the subscriber terminals. 
The master station transmits a polling signal at periodic intervals to the termination station, which responds to it by transmitting an acknowledgment signal as long as the local call is in progress. The master station detects if the acknowledgment signal is received in response to the polling signal. End-of-call indication is given to the network when the response is not received for a prescribed time interval to stop the tariff charges on the calling party.
