Abstract: An apparatus and method for controlling the air condition and heating within a vehicle interior compartment, in which the apparatus includes a fan (13), heat exchangers (14, 15), temperature sensors (26, 27, 28) and a solar sensor (29) and temperature control (47) for setting a desired temperature. The apparatus further includes a control unit (46) which is operative to calculate a theoretical interior temperature T.sub.I based only upon information from sensors (26, 29) sensing the external heat load of the compartment, a sensor (27) sensing the temperature of the air supplied to the compartment and fan current representative of the volume of air supplied to the compartment. The control unit (46) compares this theoretical interior temperature T.sub.I with the preset temperature T.sub.ISet , calculates the difference .DELTA.T.sub.I, and then controls air flow and mixed temperature T.sub.M to readjust or maintain the interior temperature within the compartment (19) at the preset temperature T.sub.ISet.

Abstract: A brake booster is easily fastened and free from play on the splash wall of an automotive vehicle. The guiding portion (10) of the booster housing (1) is provided with an annular groove (11) receiving a clamping ring (3) held on the splash wall (2) of the vehicle.

Abstract: An arrangement for mounting a brake power booster to the mud guard of an automotive vehicle. The booster is actuated by means of a push rod. An adapter which partly surrounds the booster housing is arranged between the brake power booster and the mud guard. To eliminate the engine and suction noises of the brake power booster which have a disturbing effect in the passenger compartment of the automotive vehicle and to simultaneously seal the passenger compartment, the adapter presents a ventilation port and a seal is provided between the adapter and the mud guard which is simultaneously brought in abutment against the push rod as a radial seal.

Abstract: The invention relates to a method and apparatus for electrostatic spraying of powder particles on a surface to be coated. The carrying gas powder mixture axially discharged from a nozzle is expanded by a radially discharged control air stream to thereby form the desired spray mist. The electrostatic charging of the powder is achieved by an ionized gas stream which is fed into the carrying gas powder mixture separately from the control air stream. Some of the advantages achieved by the invention are an improved spray pattern and a more uniform coating.
