Abstract: An optical fiber package (20) is provided by winding a plurality of convolutions in a plurality of layers on a bobbin. To each layer is applied an adhesive material (45) which in a preferred embodiment is a mixture comprising a reactive silicone copolymer resin, a solvent system which includes an aromatic constituent, a catalyst and a wetting agent. The mixture has a modulus behavior which is relatively stable with respect to time throughout a relatively wide operating temperature. Inasmuch as the solvent system and the method of application of the mixture are effective to control the rate of precipitation and the rate of cure of the silicone constituent, the surface roughness of the convolutions is controlled. After the desired number of convolutions have been wound, the package is subjected to a heat treatment which relieves stresses in the wound fiber and which completes the cure of the adhesive material. The adhesive material is effective to hold the convolutions together sufficiently to allow transport and deployment and to allow the convolutions constantly to be payed off over a relatively wide temperature range and over a relatively wide range of payout speeds without the use of excessive force and without breakage.

Abstract: A flow cell (10) comprises an elongate measurement zone (12), liqid introduction zones (14, 16) at each end of the measurement zone (12), two liquid specimen nozzles (18, 20) which face each other across the measurement zone (12), and sheath liquid inlets (22, 26) and waste liquid outlets (24, 28) disposed in the liquid introduction zones (14, 16). 
     The particle analyzer is designed to pass light through the liquid specimen flowing as a sheath flow in the measurement zone (12) in the flow cell (10) in order to detect individual particles. 
     Because the two liquid specimen nozzles (18, 20) face each other, it is is possible, while measuring one liquid specimen discharged from one of the liquid specimen nozzle (18, 20), to prepare the other liquid specimen in the other liquid specimen nozzle, so that the overall analysis time for both liquid specimens is considerably shortened. This is possible because, if the second liquid specimen (32) leaks out of its nozzle (20) during analysis of the first liquid specimen (30), it is flushed straight out of the adjacent waste liquid outlet (28) without passing through the measurement zone (12).

Abstract: A method and apparatus for machining a matched set of fixed and orbiting scroll members (43,50) for use in a scroll compressor. The respective wrap surfaces (47,54) of the scroll members are simultaneously machined by respective rotating cutting tools (86,186). Specifically, rotational and linear movement of the fixed and orbiting scroll members together, synchronized with linear movement of the cutting tools, causes the simultaneous machining of the scroll members (43,50) along respective wrap surfaces (47,54) that form a radially inwardly moving sealing line of contact therebetween during compressor operation. Accordingly, any systemic or random deviation from a true involute form during machining of the matched scroll member set results in complementary deviations in the respective wrap surfaces, whereby a sealed relationship between the wrap surfaces is maintained at such point of deviation during compressor operation.

Abstract: A device for switching on or off a warning device (3) of a vehicle is proposed, in which the warning device can be switched on and off as a function of the detected visual range or the speed which the vehicle has been travelling at. If, for example, the warning device is a fog light of a motor vehicle, the warning device is automatically switched off when visibility is good, even if the manual control switch (4) for the warning device has been switched on. As a result, a dazzle effect for other vehicles on the road is prevented. On the other hand, when visibility is bad and lies below a predetermined limit value, the function of the manual switch of the warning device is completely maintained. The detection of the visual range can take place by means of a focus trap (1) which is known in photo technology. <IMAGE>

Abstract: The invention relates to an arrangement for cleaning and protecting the measuring optics in exhaust-gas test devices for internal combustion engines against contamination with the aid of a flushing-air stream. Such a protection of the measuring optics by flushing air is generated in known devices by a suitable pump or a fan passing fresh air from the environment via a feed system adapted to the measuring arrangement to the measuring optics. As the measuring system does not permit complete separation of the flushing-air stream and the exhaust-gas stream, the exhaust-gas flow rate is affected by the flushing air, and the measurement results are thus falsified. An arrangement for supplying flushing air is therefore to be described, in which the influence of the flushing-air stream on the exhaust-gas stream is reduced. This is achieved by the flushing-air rate being controlled as a function of the exhaust-gas flow rate in the measuring arrangement. The arrangement according to the invention makes it possible to advantageously achieve a flushing-air flow rate which is equal to the exhaust-gas flow rate, so that the mutual influence of the flushing-air stream and the exhaust-gas stream is minimised. <IMAGE>

Abstract: A method of making a composite casting wherein a casting mold is provided for receiving a melt and a preformed metallic or intermetallic insert (10) is positioned in the mold cavity (30). The preformed insert includes a working portion (10C) for incorporation in the casting and gas seal-forming means (11) located at a region of the insert at least outboard of the insert portion (10A,10B). A melt is introduced into the mold (30) about the insert (10) and is then solidified to provide a composite casting having the insert working portion (10C) disposed in the solidified melt and as-cast gas seal regions located outboard of the insert working portion in the casting. The casting is then subjected to elevated temperature and isostatic gas pressure conditions wherein the as-cast gas seal regions are effective to inhibit gas penetration between the insert working portion and the solidified melt therearound so as to permit formation of a sound, void-free metallurgical bond therebetween. The hot isostatically pressed casting can then be trimmed to remove, if desired, those outboard portions containing the gas seal regions, leaving a finished casting having the insert working portion metallurgically bonded therein in a sound, void-free manner.
