Patent EP-0267397-A2 (EP)
Inventor: WENDT HANS JOACHIM ING GRAD
IPC: B64C13/50
Filed: 1981-07-23
Abstract: The transmission network (24) uses a number of intermeshed optical conductors (11,12) for transmission of digital light pulses. The pulses represent the control signals provided by the control elements fed to the network (24) via signal processors (10) imcorporating a mixer (15) and information systems (16,17,18). The energy supply for the transmission network (24) uses a number of alternate energy sources, e.g. the aircraft engine, as auxiliary turbine, a slipstream turbine or an electric battery. The sources are switched into the network via three redundant coupling stages under control of respective monitoring and switching devices and a central microprocessor monitoring and switching stage coupled to the network.

Abstract: An apparatus for transmitting data from the exterior of a gun tube to a projectile (10) positioned within the gun tube (12) utilizes at least two electromagnetic-acoustic transduction devices, one such device positioned on or near the exterior periphery of the gun tube and one such device positioned on or near the interior periphery (16) of the gun tube within the bore. Such data may be used to update target or trajectory information used by a projectile. Transmission of such data, at high data rates, just prior to firing the projectile from the gun tube, enhances the probability of target kill or damage. High data rates, compatible with SMART projectile requirements, are made possible by ultrasonic signal frequencies in the range of about 500 Khz to about 2,500 Khz. Phase-shift-keyed modulation may be employed to impart data onto the ultrasonic signals.

Abstract: The mammalian cells are immobilised in a growth chamber and are continually washed with medium through a closed circulation system. Separate from the growth chamber in the circulation there is a module with a semipermeable membrane through which the nutrients are fed in and/or the metabolic products are removed. The device is very suitable for continuous cultivation of immobilised or adherent mammalian cells under controlled conditions over lengthy periods.

Abstract: A telephone exchange, now often called a switch, includes a switching network of the space division type which switches PCM highways, and includes a number of sub-networks (SEG1, SEG2 ... SEGN) each of which is a plural (e.g. three) stage array. When a call is to be set up it is set up via one of these sub-networks, and a reserve path chosen for it through a different sub-network. The identity of this reserve path is noted in memory for use if the path via which the connection is actually set up fails. If that happens the call is switched to the reserve path. 
     This facility can also be used for "block transfer" of all calls in a sub-network, e.g. when the latter is taken out of service for maintenance. 
     In one embodiment in which three stages are used, part at least of the middle stage is common to all sub-networks. 
     Such an apparently large amount of switching cross-points is not too "cost ineffective" since the switching sub-networks are made up of relatively cheap VLSI units. Since the physical paths are e.g. PCM-TDM highways which thus carry heavy traffic such precautions to maintain high system integrity are well worthwhile.

Abstract: A method of making a ceramic mold includes covering both a pattern member (86, 88) and a body of expansion material with a layer (96) of ceramic mold material. The body of expansion material has a coefficient of thermal expansion which is greater than the coefficient of thermal expansion of the ceramic mold material. The layer of ceramic mold material and the body of expansion material are heated. This results in a cracking of the layer of ceramic mold material by the body of expansion material due to greater thermal expansion of the body of expansion material as it is heated. During the step of heating the ceramic mold material and body of expansion material (92), the pattern member is melted to separate the pattern from the layer of ceramic mold material.

Abstract: A method for the completion or work-over of a well comprises the step of using a solids-free, non-aqueous well-bore fluid comprising a halogenated organic compound as a completion or work-over fluid. The fluid has a specific gravity in the range 0.9 to 2.3. 
     Preferred halogenated organic compounds are brominated aromatic ethers, diphenyls, aliphatic hydrocarbons, benzene and alkyl benzenes. 
     The halogenated organic compound may be dissolved in an organic solvent. The relative proportions may be chosen to provide a well-bore fluid having a desired specific gravity. 
     The fluids are non-corrosive, thermally stable and non-damaging to formations.

Abstract: Deconvolution of up to three overlapping chromatographic peaks is provided in which pure spectral components are extrapolated from a Euclidean-normalized expression of chromatographic data in the space of the three principal factors. A coordinate transformation to planar coordinates after expansion in factor space and before extrapolation yields the simplicity of linear extrapolation in combination with the inherent accuracy of Euclidean, as opposed to standard, normalization. The estimation of the pure component spectra permits the constructions of a concentration matrix. Improved estimates and an error bound are provided by applying assumptions of non-negativity and limited deviation from the means to the concentration matrix.

Abstract: A door mounted to slide across an opening in a structure (for example, a vehicle body) has a handle(11) pivotally, or slidably, mounted on the door and biassed to a central position by springs (18, 19) acting on an arm (14). Movement of the handle in one direction (to open the door) causes release of the door latch by the arm (14) pulling a rod(20) and operating a pivoted lever (24) and an operating rod (25). Simultaneously, a connecting rod (29) is pushed, rotating a lever (28) to open a second latch (27) for securing the door in an open position. Continued applioation of force to the handle (11 ) in the same sense draws the door across the opening to latch it in an open position. 
     Pivoting of the handle (11) in the opposite direction causes the arm (14) to push the rod (20) and lever (24) pulling the connecting rod (29) and rotating the lever (28) to release the second latch (27). The operating rod (25) does not move because of a lost motion connection (26) with the lever(24). Continued application of force to the handle 11 draws the door back across the opening to latch it in the closed position. The latches may also be operated by a handle (31) of the second latch (27) inside the vehicle.
