Abstract: An ozone containing gas stream is produced from oxygen by
subjecting oxygen to an electric discharge and the ozone is
then adsorbed on to a solid adsorbent, such as zeolite, the
oxygen containing stream leaving the adsorbent is recycled to
the ozonising process. Periodically, oxygen adsorbed on the
adsorbent is desorbed by co-currently passing a purge gas over
the adsorbent and the desorbed oxygen is also recycled to the
ozoniser. Lastly ozone is desorbed from the adsorbent by a
counter-current flow of purge gas and used in an ozone
demanding process.

Filed: 1998-10-29
Abstract: A method and a system for acquiring data frame timing in a
discrete multitone modem system in which an acquisition frame is
generated having a first predetermined number of impulse signals. Each
impulse signal is spaced in time by 2(P + 1)T s , such that 1/T s  is a sample
transmission rate, and P is a time length in samples of a cyclic prefix that
is added to a data frame. The cyclic prefix length P is chosen such that a
channel impulse response seen at a receiver effectively spans no more than
P + 1 samples when a received signal is sampled at the 1/T s  rate. Data
frames are generated subsequent to the acquisition frame. Each data frame
includes a cyclic prefix and at least as many data samples as samples of the
cyclic prefix. The acquisition and data frames are converted to an analog
signal for transmission. The received acquisition frame is sampled and a
summation window is advanced one sample at a time through the received
acquisition frame. The sampled acquisition frame is summed over each
summation window, with each summation window spanning P + 1 samples
of the acquisition frame. A maximum summation value is determined as
the summation window advances, and a data frame boundary is determined
based on the summation window corresponding to the maximum
summation value. A channel impulse response is estimated based on the
P + 1 samples of the received acquisition frame corresponding to the
maximum summation value, and data is coherently detected based on the
estimated channel impulse response.

Abstract: A brace or limb protector, which in hinging, matches the complex bending motion of the natural knee of a human being. The hinge mechanism has supports for the upper and lower leg which are attached to each other by a hinging mechanism which is connected to and pivots on the support at a first position (50) and a second position (72) respectively. Connection of the supports at the first position (50) is to the plate of the hinge mechanism and at the second position (72) to the arm which pivots on the plate at stud (61). This configuration of the hinging system allows the hinge mechanism of the brace or limb protector to follow the natural movements of the human knee at all degrees of natural movement.

Abstract: A power steering apparatus, including a pump, a power cylinder, a control
valve and a switching valve. The switching valve is for connecting the cylinder
chambers in accordance with pressure change of the operating fluid responsive to
operation of the control valve in order to return the steering wheel toward a neutral
position. 
     When the rotation of the steering wheel is substantially stopped, the switching
valve reacts to the pressure change in order to connect the cylinder chambers, so as that
the higher hydraulic pressure of one of the cylinder chamber releases to the other.
This hydraulic pressure releasing of the operating fluid returns the power piston toward
the neural position, smoothly. The steering wheel also returns toward the neutral
position in accordance with the return of the cylinder piston, so as that restoring force
of the steering wheel is enhanced.

Abstract: To set the moisture profile of a fiber web material (1) in a papermaking or finishing machine, it is treated with electromagnetic waves as microwaves and/or high frequency (HF) waves. The field energy of the electromagnetic waves is distributed evenly across the web (1), when the web (1) has a dry content of 60-95%. The web (1) is supported in its movement path, at least at the zone subjected to electromagnetic waves. The web drying action is mainly through the exposure to electromagnetic waves, or only partially by them to compensate for differences in the moisture content across the web (1). An Independent claim is included for a web drying station, where the web (1) is moved past a microwave transmitter (2). Preferred Features: The microwave transmitter (2) has one or more hollow waveguides, each linked to a microwave source, and distributed evenly across the web (1). The web (1) moves over a rotating cylinder (3) at the microwave transmitter (2) zone. The cylinder (3) has a mantle or an outer cladding (4) of a material which absorbs microwaves less well than the web (1). The outer cylinder cladding (4) has a thickness of 5-150 mm and especially 10-50 mm. The support for the web (1), in its path from at least a fourdrinier (5), has a lower microwave absorption than the web (1). The path for the web (1) can carry it past at least two HF electrodes of different polarities. The electrodes are electrode rods, condenser plates and/or rotating cylinders. The web (1) moves round a rotating cylinder (3), preferably supported by a fourdrinier (5). The metal cylinder (3) can form an electrode, with a further rod electrode and/or condenser plate on the other side of the web (1), of a different polarity. The cylinder (3) can be cladded with an electrical insulation material. Where the web passes round the cylinder (3), at least two rod electrodes of different polarities generate HF waves which penetrate the web (1) at least partially. The assembly has an electromagnetic shrouding (6).
