Title: Axle-weight transfer device for rear two-axle vehicle
Inventor: SAITO TETSUYA
IPC: B60G5/04
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an axle-weight transfer device of a rear tw-axle vehicle capable of controlling a proper axle-weight distribution ratio even while travelling when a detected load data varies due to road surface input and change of a vehicle position. SOLUTION: An axle-weight transfer device can adjust an axle-weight distribution ratio between rear two axles by an air spring and performs a proper axle- weight distribution ratio by controlling supply air pressure to the air spring. In an axle-weight transferring routine for this air pressure control, a detected load data W is memorized at the time when a vehicle stops (step S12), and at the time when an axle-weight transfer switch is operated to be switched on while travelling, supply air pressure to the air spring is controlled by computing target pressure from the memorized load data W (step S22). Once the supply air pressure reaches the target pressure, air pressure control of more than that is finished (step S26).

Title: Preparation of ketone
Inventor: MATSUKUSU BURAUN
IPC: C07C67/10
Filed: 1994-04-26
Abstract: Described is a novel process for the preparation of ketones, for example CF3C(O)CH3, CF3C(O)CH2C(O)CF3 and CF3C(O)CF2H. In this process, ss-keto esters are transesterified and decarboxylated with a carboxylic acid, for example trifluoroacetic acid, in the presence of a catalyst, in particular an "onium" salt of a carboxylic acid or an effective amount of a proton-liberating acid, preferably a sulphonic acid such as alkyl- or arylsulphonic acids, or a mineral acid. It is expedient to carry out the process under anhydrous conditions. Therefore, no acetals or hydrates are formed, so that a dehydration step can be dispensed with. A further advantage of the process is the simple procedure. If a sufficiently active carboxylic acid is used for the transesterification reaction, for example trifluoroacetic acid, the presence of an additional catalyst is not required.
