Abstract: The invention provides a cabinet (10) formed from a reinforced plastics material which is water tight. The cabinet (10) permits the washing of incontinent patients with a minimum risk of infection to the cleaner. In addition because the unit has an entry door (15) and internal smooth washable surface, the entry door (15) being sealable with a rim of a doorway 14), of the cabinet (10), there is a minimum risk of soiling of a bathroom or lavatory floor. 
     A self contained pumping unit (29, 30) pumps soiled water from within the cabinet (10) to a lavatory bowl. 
     The cabinet (10) may be static or mobile and a douche unit (25) may be provided, with a mixer tap (23) for cleaning a patient.

Abstract: Articles contaminated with soil etc are cleaned by contact with a non-chlorinated organic solvent having a relatively low flashpoint, such contact being made at a temperature below such flashpoint. The articles are then contacted with an aqueous rinsing medium at a temperature below the flashpoint of the solvent. These steps lead to contamination of the solvent and the rinsing medium and to free them of the contaminants, which are substantially non-volatile, the contaminated solvent and rinsing medium are fed to a steam distillation unit in which the rinsing medium and solvent are co-distilled at a temperature above the flashpoint of the solvent. The steam distillation is carried out in a fire hazard containment zone in which oxygen is substantially excluded during normal operation of the steam distillation unit by the water/solvent vapour generated, and during commencement and cessation phases of steam distillation by the generation of an inert gaseous fluid.

Abstract: The invention relates to a control processor of a system, particularly for telecommunication applications, to an equipment for emulating it and to a method of carrying out an emulation. 
Control systems based on processors use either microprocessors or DSPs (Digital Signal Processors) connected to a program memory, containing instructions necessary to realize the desired control, and to a set of input and output ports. 
The program normally reads the content of the input ports and, on this basis, calculates suitable values and write them in the output ports. 
     Such a solution is often insufficient if the response times required to the control system are limited. 
     By realizing a suitable processor whose set of instructions depend on the control to be realized and in which the control instruction which is executed each time is read out not from the program memory as usual, but from the input registers that indicate the status of the electric system, a remarkable increase in speed and reliability is obtained.

Abstract: The present invention relates to a clamping device for semipermanently fixing a part, such as a fluid conveying hose, dustproof bellows, axial boot or the like, on the circumferential surface of an desired mating device. According to this invention, even if such part looses its elasticity owing to aging, the clamping device maintains the permanent stable firm clamping state. For this purpose, the inner and outer overlap portions (11a, 11b) of the clamp band (11) are forced by an operating tool to spread until the seizing tooth (18a) of the inner overlap portion (11a) and the fixed tooth (22b) of the outer overlap portion (11b) seize each other, thereby contracting the bore diameter of the clamp band (11). This state is locked by a prop key (23) extending from the outer overlap portion (11b) to engage the inner overlap portion (11a), while an elastic hump (25) for storing the spring force acting circumferentially of the clamp band (11) is outwardly bulged from the outer overlap portion (11b).

Abstract: An automatic contrast adjusting device which is capable of providing an optimum LCD contrast for a user's eyes as the user desires. A CPU references a characteristic table listing temperatures vs. liquid crystal drive voltages in a RAM in response to temperature data from a thermistor, reads a PWM value (liquid crystal drive voltage) corresponding to the temperature data, and outputs a PWM pulse of a duty ratio corresponding thereto. On the other hand, when the user manually adjusts the contrast by handling a contrast switch, characteristic data in the RAM is corrected in response to the adjustment amount, and is then written into an EEPROM.

Abstract: This invention embodies devices comprising Group III-V compound semiconductors in which p or n or both p and n regions are formed by a superlattice (13, 14) selectively doped with an amphoteric Group IV element dopant (23) selected from carbon, germanium and silicon. The superlattice includes a plurality of periods (20), each including two layers (21, 22). Depending on the conductivity type, only one of the layers in the periods forming the superlattice region of said type of conductivity is selectively doped with said dopant, leaving the other layer in these periods undoped. The superlattice is formed by Molecular Beam Epitaxy technique, and the dopant is incorporated into respective layers by delta-doping as in a sheet centrally deposited between monolayers forming the respective layers of the period. Each period includes 5 to 15 monolayers deposited in the two layers in a numerical ratio corresponding to a cation compositional ratio in the compound semiconductor. Low growth temperatures, e.g. ranging from 410 to 450°C lead to mirror-like surfaces. For a compound semiconductor Ga 0.47 In 0.53 As, the GaAs/InAs ordered superlattices with eight monolayers per period are grown in a ratio of 0.47/0.53. At free carrier concentrations of 10¹⁶cm⁻³, carrier mobilities of 200 and 2300 cm² /Vs for p-type and n-type are obtained with carbon as the amphoteric dopant.

Abstract: We have discovered that silica-based optical fibers (e.g., 33) that are doped with Ge, Al and a rare earth (e.g., Er) can be very susceptible to hydrogen-induced attenuation change. For instance, such fiber can exhibit loss increase rates that are, at 20°C, 10⁶ times larger than those of a standard single mode fiber. We also believe that transition metal-doped silica-based fibers can exhibit large hydrogen-induced attenuation change. In many circumstances (e.g., amplifier fiber, attenuator fiber) significant attenuation change of optical fiber is undesirable. We disclose that such change can be substantially eliminated by provision of hydrogen gettering material and/or a "hermetic" fiber coating. It is currently preferred to provide silica cladding material that is a hydrogen getter, and also provide a "hermetic" fiber coating. Containment of the fiber, together with a quantity of a gettering material (e.g., ErFe₂) in an essentially hermetic enclosure is also disclosed.
