Patent CA-2228282-A1 (CA)
Inventor: BEARD ANDREW M
IPC: F16F13/00
Filed: 1996-09-06
Abstract: An active vehicle suspension employs a multi-point support system between a vehicle's chassis and cab. Each support point has an isolator which includes a linear hydraulic actuator (52) that is connected at its quiet end to the payload by a passive vibration isolator (62) and is connected at its vibrating end to the chassis. Each isolator also has a support spring (68) to off-load the majority of the weight of the cab from the hydraulic actuator. An accelerometer (78) is mounted to sense movement at a point between the linear hydraulic actuator and the passive vibration isolator. An electrical signal produced by the accelerometer is processed to operate a hydraulic valve (26) that controls movements of the hydraulic actuator so that transmission of vibrations from the chassis to the cab is attenuated.

Title: Fire-resistant facade or glass roof
Inventor: TOENSMANN ARMIN
IPC: E04D3/08
Filed: 1998-02-24
Abstract: A fire-resistant facade or glass roof has a supporting structure consisting of post and beam sections in which the post and beam sections define frame fields provided with a fire-resistant glazing. The beam and post sections (21) should be made of aluminum and form closed structural units which can be jointly manufactured for use in fire-resistant constructions. The beam and post sections each have a core section (22) which absorbs the static loads and which is surrounded in its outer wall area by a U-shaped hollow chamber for accommodating molded substances (36, 36.1) consisting of a heat-absorbing, hydrophilic adsorbent having a high proportion of water. Connecting webs are provided between the outer wall of the U-shaped hollow chamber and the core section (22) which ensure a low heat flow from the outer wall of the hollow chamber to the core section. As a result, crystal water is released when the control temperature of the hydrophilic adsorbent is attained and by means of which the metal construction is cooled.
