Abstract: PCT No. PCT/SE90/00758 Sec. 371 Date May 26, 1992 Sec. 102(e) Date May 26, 1992 PCT Filed Nov. 22, 1990 PCT Pub. No. WO91/08389 PCT Pub. Date Jun. 13, 1991.In order to be able to modify in a simple manner the response of a supercharged internal combustion engine as a function of the engine load, an arrangement is proposed in which the driver may regulate the charge air pressure build-up by means of a manual setting control. The manual setting control is connected to an electronic control unit which, as a function of detected engine parameters, controls the supercharging pressure with respect to desired values stored in the control unit. As a function of the adjusted position of the setting control, a reduction of the charge air pressure which is dependent on the engine load is effected. In this way, the driver can choose which response the engine will have for partial load ranges, where it is possible either to have full charge air pressure at all throttle positions or a gradual increase of the charge air pressure on increasing throttle opening.

Title: Method for the separation of hydroxyacetone from hydroxyaceton containing phenol
Inventor: VAN BARNEVELD HEINRICH
IPC: C07C37/74
Filed: 2000-01-27
Abstract: The method is materialized by reduced energy amount in the separation of the hydroxyacetone, by limiting the phenol losses. It is used for the separation of hydroxyacetone from phenol-containing hydroxyacetone which is produced in acidic catalytic degradation of cumenehydroperoxide by the steam-like phenol-containing hydroxyacetone with a base. Combination is made between a distillation and reaction column when either the steam-like phase taken from the head of the distillation column is fed to a reactor where it reacts with the base, or the reaction takes place in a distillation column which is supplied not only with the distilled phenol-containing hydroxyacetone but also with the base. The method can also be applied in the flotation of the raw phenol removed as waste in the Hawk's synthesis. 10 claims, 3 figures

Abstract: The present invention describes pyridazoline compounds of formula which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX 2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COC-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marked non-steroidal anti-inflammatory drugs (NSAIDs). 55 claims

Abstract: 在CDMA系统中用于测试现用基站收发信机(BTS)的基站测试装置中,为指定给BTS的服务区的相应扇区配置有多个前置衰减器,并包括在相对应的BTS的多个扇区TRX中,以便模拟测试扇区和它的邻近扇区之间现用BTS的软越区切换测试。为此,构成每个前置衰减器,以便可实现至少三种衰减值,例如0dB,－3dB和－50dB,并在切换控制器的控制之下逐个选择。通过这种结构中,测试扇区的前置衰减器被置于0dB的状态,而其邻近的前置衰减器和其它衰减器则分别被置于－3dB的状态和－50dB的状态。在上述方法中,控制衰减值有助于模拟现用BTS的软越区切换测试。
