Title: Adaptive mode anti-lock brake controller
Inventor: KADE ALEXANDER
IPC: B60T8/58
Filed: 1987-07-03
Granted: 1992-07-21
Abstract: ADAPTIVE MODE ANTI-LOCK BRAKE CONTROLLER Abstract of the Disclosure A wheel lock control system is described which utilizes both independent and select low modes of wheel lock controlled braking.  When braking on a surface in which the coefficients of friction between the two sides of the vehicle are substantially different or when the vehicle is undergoing severe steering maneuvers while braking, the wheel lock control system utilizes a select low mode of braking for the vehicle rear wheels so as to maintain vehicle stability. However, when the four wheels are being braked on a substantially uniform coefficient of friction surface, the wheel lock control system utilizes an independent mode of braking for each of the wheels of the vehicle so as to minimize the vehicle braking distance.

Abstract: LOW DENSITY FROTHED MINERAL WOOL PANEL AND METHOD            Abstract of the Disclosure A method for the manufacture of very low density mineral wool structural panels on a moving foraminous support wire by frothing a dilute aqueous dispersion of mineral wool is disclosed.  The froth, a mass of delicate, non-resilient and nonuniform bubbles among the entangled mineral wool fibers readily breaks, is stripped of water and dried without substantial loss of the highly open, porous structural configuration by a first controlled rate of maturation dewatering followed by brief pulses of high vacuum.  Then the open structure is rapidly stripped of remaining water and dried by passing high volumes of heated dry air through the structure with continued vacuum.   The drainage water may be recycled in the process to main-tain a low level of binder and any frothing aid additions.
