Title: Emergency escape apparatus
Inventor: LYLE IAN CAMPBELL
IPC: A62B1/14
Filed: 2002-01-17
Abstract: A self-contained emergency escape apparatus utilising an easily deployable column such as a rope. Attached to the upper end of the column are a pre determined number of friction based delay mechanisms (FBDM) with harness attachments. The friction based delay mechanism manipulates the path of the column to the extent that a body/bodies which are allowed to naturally fall will be slowed by the mechanism to a rate considerably less than that of gravity. The internal parts of the friction based delay mechanism may be adjusted depending upon the weight of the escapee, and further FBDMs may be fitted to the upper end of the column after deployment should the need arise.

Title: Optical signal demodulators
Inventor: PARSONS NICHOLAS JOHN
IPC: H04L27/22
Filed: 2002-01-23
Abstract: A planar waveguide optical demodulator comprises an unbalanced Mach-Zehnder interferometer. The modulated signal is input into the demodulator and split into two channels 134, 136. A delay of approximately one signal symbol is introduced on a first signal with respect to a second signal by propagating that first signal along a longer waveguide. The optical length of the interferometer arms can be adjusted by changing the temperature of the waveguide. In this way a phase shift of + or -   f  /4 can be tuned on the signals propagating each interferometer arm respectively. Changing the temperature tunes the interferometer thereby achieving maximum signal recovery. Other interferometer arrangements, such as Michelson configuration can be used. Also, a multi-mode interference coupler can be used to couple the signal and introduce a phase shift required for demodulation. The demodulator optical and electro-optical components can be constructed on a single optical chip.

Title: Preventing toppling forward of an agricultural vehicle with a raised weight elevating the centre of gravity by limiting brake force
Inventor: DENEIR STEPHAN
IPC: B60T11/224
Filed: 2002-06-01
Abstract: An agricultural vehicle eg. a combine or forage harvester has ancillary equipment eg. a header, that may be raised and lowered relative to the ground with consequential changing of the position of the centre of gravity of the vehicle. The vehicle also has a hydraulic braking system comprising a master cylinder 10, 10' and a slave cylinder 12, 12'. In one embodiment, the braking system has variable capacity provided by a pressure relief valve 26 for limiting the hydraulic pressure applied to the slave cylinder 12, 12' when the vehicle is in road mode, determined from a selected drive ratio, vehicle speed or height of the header. In other embodiments, pressure may be divided between slave cylinders by a spool valve (fig 2-4), and the system may have bypassable pressure amplification (figs 3 & 4). This ensures that the braking force does not exceed a safe limit below which the vehicle does not risk toppling forwards when braking. The brake system have two pedals and two hydraulic circuits allowing steering by braking one side of the vehicle.
