Abstract: The disclosed method relates to a method for recording flow boundary layers in liquid media by photochemical means. According to the invention, surfaces which can be developed in a plane and to which a photographic film sheet is cemented are exposed under steady-state conditions to the flow of a liquid medium containing a dissolved agent reacting with the photo gelatin layer. The liquid medium may contain agents furnishing HS-ions or agents capable of dissolving silver halide or reducing silver halide. If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action. With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded.

Filed: 1981-07-16
Granted: 1989-08-23
Abstract: A glass fibre for optical communication is formed by a vapor deposition process on the inside surface of pure silica substrate tube. The substrate forms the outer cladding whilst the inner and core are formed by the deposited layers. An intermediate layer of the cladding has a refractive-index similar to pure silica but due to compensating dopants. Thus deposition and sintering temperature is reduced. The inner layer of the cladding is however undoped pure silica, thus reducing absorption losses in this important region.A step in a process for making optical fibres comprising collapsing a tubular substrate to provide a preform is carried out in a stream of pure chlorine vapour acting as a drying agent.

Title: Segmented extendible boom
IPC: B66C23/64
Filed: 1980-12-29
Granted: 1984-10-24
Abstract: A longitudinally extendible, segmented boom structure includes a plurality of hollow, substantially V-shaped segments (10) which are pivotally connected to adjacent segments for storage. A series of load-bearing cables (134) extend through the segments for carrying loads. The segments have uniform cross-sections and progressively increasing lengths. Segments are stored in rolled-up form on a reel (12) by pivoting the segments to form a coil of nesting segments. Each segment has laterally extending side flanges (108) through which longitudinally extend the pre-tensioned load-bearing cables. The cables pass through the flanges on opposite sides of the boom segments for supporting vertical loads and resisting side loads on the boom. A second set of auxiliary cables (79) on the underside of the boom is automatically payed out as the boom is extended. The auxiliary cables prevent the extended segments from collapsing when inverted. The center point of the segment reel is adjusted in elevation to automatically feed boom segments at an optimum angle into a segment dispenser and boom support structure which has rollers thereupon for cooperating with corresponding lands and grooves on the segment flanges.

Patent EP-0157004-B1 (EP)
IPC: F02D41/14
Filed: 1984-12-22
Granted: 1989-10-11
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine and includes an exhaust-gas sensor which is exposed to the exhaust gas of the internal combustion engine. The exhaust-gas sensor indicates the air ratio lambda and preferably has a two-level characteristic. The sensor output signals are acted upon by a follow-on controller which is preferably a PI-controller. The controller output quantity acts upon the mixture composition in a corrective fashion. In this arrangement, the control oscillation of the controller output quantity is adjusted to a predetermined amplitude by means of a superposed control. In particular, the integral component of the control oscillation is influenced in a manner causing it to have the same amplitude as the proportional component while in the steady operating condition. Thus, it is possible to maintain the maximum control frequency in any operating range of the internal combustion engine so that the controller always operates at its optimum. In addition, the effects of deviations occurring from one engine to another or from one exhaust-gas sensor to another as well as of long-term variations are suppressed.
