Patent EP-0376945-B1 (EP)
Title: Control of supercharged internal combustion engines
IPC: F02B1/04
Filed: 1988-05-07
Granted: 1993-04-07
Abstract: In a turbocharged diesel engine (10), the charging pressure PLa is adjusted to run the engine (10) with an empirically determined optimum fuel consumption. A charging pressure feedback signal PLa is fed to a regulating device (40) which receives various operating parameters, including MEd which represents the power output. A characteristic field in a memory zone (50) in the regulating device (40) determines a control variable (TV) which operates a turbine by-pass valve (22) via an electro-pneumatic converter (28) and a pneumatic (vacuum) actuator (26). The caracteristic field is such that the charging pressure PLa is reduced in the part load range (cruising speed) to improve fuel consumption.

Title: Treading device for wheels
IPC: B60C27/00
Filed: 1988-05-23
Granted: 1992-09-02
Abstract: According to the present invention, rotors (3) and a retainer (4) are moved on a road surface in accordance with the rotation of a wheel (7), and, as long as there is a relative movement between the wheel (7) and road surface (5), a belt-like member is turned. While the vehicle travels normally, the wheel rotates on a blade placed stationarily on the road surface; and, even when the slipping of the wheel occurs, the wheel bumps off the blade backward as it slips, so that the belt-like member is thereby further turned. When the wheel and blade slip on the road surface when the wheel is braked, the road surface turns the belt-like member. Accordingly, the blades are moved down sequentially in any case to be arranged on the road surface in good order and rest, and the wheel runs on the blades as it treads thereon. Therefore, the treading of the blade is done reliably. Even when the size of the blades is small, an unreasonably large force is not applied thereto, and this enables the dimensions of a blade retaining means to be reduced.

Abstract: In the case of such a reticle for optical sighting devices, a cross-wire part (FT1) inside a frame part (R1) is connected to frame segments (RS). Said frame segments (RS) have perforations (P) which are in alignment with a contact surface (A1) on a web (S1) of an annular carrier part (T1). The contact surface (A1) of the carrier part (T1) is provided with an adhesive (K), which in the event of an increased temperature penetrates through capillary action into the perforations (P), so that the frame segments (RS) bear in a planar fashion on the contact surface (A1). Due to different coefficients of thermal expansion of the carrier part (T1) and of the reticle, the inner          cross-wire part (FT1) receives a pretension sufficient to achieve an unchanged flatness in the operating temperature range. <IMAGE>

Abstract: A process is provided for removing water from a mixture of hydrogen fluoride (HF), a carboxylic acid, e.g., acetic acid, and water by extractive distillation in the presence of a Lewis base as solvent, which does not azeotrope with water, forms bonds with the HF and carboxylic acid which can be broken by heat and has a boiling point at atmospheric pressure at least about 20 DEG C above that of tne carboxylic acid, e.g., N-methyl-2-pyrrolidone, and taking off an overhead vapor comprising a major proportion of the water in said mixture. The extractive distillation may be advantageously integrated in an overall process with the production of an aromatic ketone, e.g., 4-hydroxyacetophone, by the Friedel-Crafts acylation of an aromatic compound, e.g., phenol, with the carboxylic acid, using HF as catalyst, to produce a product mixture comprising the aromatic ketone, HF, carboxylic acid and water, and the removal of aromatic ketone from the product mixture by means of a solvent assisted distillation.

Abstract: The resistivity of particulate matter in a gas stream, such as a combustion gas stream produced in a coal-fired power plant, is measured by collecting a sample of the particulate on the surface of a porous ceramic cylinder (62), either with or without an applied collection voltage, and then determining the resistance of the sample with a compound measurement electrode (82) having multiple conductors (84,86). The referece electrode (89) and the measurement electrode (82) are spirally wound on the ceramic cylinder (62) in an interdigitated manner, so that the two (82,98) are laterally adjacent down the length of the cylinder (62). The pressure within the cylinder (62) is controllable, with a pressure below atmospheric being applied to draw the particulate to the surface and ascertain when a sufficient sample for measurement is present, and a pressure above atmospheric being applied to blow away the sample after the measurement is completed, thereby preparing the instrument for the taking of another sample.

Abstract: The process comprises three stages, namely an oxygen bleach which is optionally combined with a hydrogen peroxide bleach (EOP stage), an ozone bleach (Z stage) and a peroxide bleach (P stage). According to the invention, the residual oxygen content of the exit air from the Z stage is completely reacted in the EOP stage, and the effluent of the Z stage is used for dilution between the EOP and Z stages and/or for ash removal from the pulp after bleaching. It is advantageous in this case to control the temperature, the NaOH supply and the O2/H2O2 ratio in the EOP stage, so that the oxygen consumption at a constant conversion is adjusted to the residual oxygen content of the exit air from the Z stage.

Abstract: Two aluminum-copper foils are joined with their aluminum surfaces in contact for use as an outer layer material (20) of a multilayer printed wiring board. In producing this board, an outer layer material, a prepreg (2), an inner layer material (1), a prepreg (3) and an outer layer material (21) are built up in this order. Therefore, the aluminum portion of the outer layer material (20) works as a conventional mirror plate and a dummy plate. Further, the aluminum surfaces can be easily released from each other and work as conventional mold releasing films. The outer layer material (20) has aluminum surfaces tightly adhered to each other and does not permit resin scums or foreign matter to adhere thereto unlike that of the prior art, this structure further prevents scars or damage caused by impact from developing. Moreover, since no mirror plate is used, the operation steps can be simplified and the built-up operation can be easily and automatically carried out. It is also possible to use plastic metal foils of aluminum alloy, copper, brass, soft steel, lead alloy and the like instead of the aluminum foil.
