Title: Combustible wood product
Inventor: JONES DAVID
IPC: C10L5/44
Filed: 1992-10-05
Abstract: Controlled distillation of softwood timber sticks in the presence of a restricted supply of oxygen removes water, alcohol and other volatiles boiling at less than about 110 DEG C at ambient temperature, and is terminated while the sticks remain intact with a substantially cellulosic molecular structure. The processed sticks are resistant to crumbling and gold yellow to pale brown in colour, and contain at least 4% by weight of oils and resins boiling at at least 120 DEG C at ambient pressure. As exemplified the distillation involves raising the temperature of a distillation vessel slowly from 40 - 110 DEG C over fifteen hours and thereafter increasing the temperature to about 120 DEG C over thirty minutes.

Patent GB-2303565-A (GB)
Title: Exhaust gas treatment
Inventor: MA THOMAS TSOI-HEI
IPC: F01N13/02
Filed: 1995-07-26
Abstract: A spark ignition internal combustion engine 10 is described having an exhaust gas after-treatment system that includes a three-way catalyst 18 and an NOX trap 20. The NOX trap 20 stores NOX when the exhaust contains excess oxygen and is regenerated by releasing the NOX gases for reduction by the catalytic converter to N2 when the exhaust gases contain an excess of hydrocarbons (HC) and/or carbon monoxide (CO) in the absence of oxygen. The engine 10 is operated with an overall lean air/fuel ratio, during which the NOX gases contained in the exhaust gases are stored in the trap. The trap is regenerated by briefly injecting fuel from tank 14 - or vapour canister 16 - at regular intervals to a point upstream of the trap, thus supplying a reducing atmosphere to it, and enabling the catalyst within the trap to reduce the NOX. During this regeneration the engine is run with a stoichiometric air/fuel ratio.

Title: Angular rate sensor electronic balance
Inventor: HULSING II RAND H
IPC: G01C19/5607
Filed: 1996-05-20
Abstract: An angular rate sensor 20 includes a plurality of spaced apart vibrating beams, for example, four beams, defining a pair of outer beams 22, 26 and a pair of inner beams 24, 28. Each outer beam is mechanically coupled to an inner beam by way of an interconnecting member 30, 32. The outer beams are excited to cause them to vibrate in the plane of the beams and 180 degrees out of phase with the inner beams. In order to force the quadrature acceleration components to cancel out when geometric mismatches between the beams exist, the drive beams are driven separately at different amplitudes. By driving the beams at different amplitudes, the quadrature acceleration components of both beams can be matched, forcing such components to cancel to enable a single demodulator to be used for the Coriolis or angular rate signal.
