Title: Fluorinated polymers and copolymers containing perfluoropolyether blocks
IPC: C07C43/12
Filed: 1988-12-09
Abstract: By means of radical starters, fluoroolefins are polymerized 
in the presence of perfluoropolyethers containing, at one 
or at both ends, a bromine atom, in such amounts that the 
weight ratio between perfluoropolyethers and fluorinated 
olefins in the resulting product ranges from 4/1 to 1/50. 
The bromine-containing perfluoropolyethers to be employed 
in the process have a molecular weight ranging from 400 
to 10000 and, preferably, from 600 to 8000. The resulting 
polymeric products comprise sequences of perfluoroolefinic 
units and perfluoropolyether blocks.

Title: Improved high pressure oxygensaturated water treatment apparatus
IPC: C02F1/74
Filed: 1988-08-03
Abstract: The improved high pressure oxygen-saturated water treatment apparatus (10) of the present invention functions to provide super-saturated oxygen treatment to waste water for purification thereof. The apparatus includes a pressurized treatment tank (12) having a substantial longitudinal dimension, with a chamber separation plate (14) forming two interconnected chambers (16, 18) in the tank (12). An input conduit for flowing waste water into the first chamber of the tank is provided. An oxygen input conduit (22) is connected to the tank for providing oxygen-containing gas under substantial pressure within the tank. An oxygen output conduit (30) is also disposed on the tank (12) for receiving the oxygen-containing gas from the tank to form a pressurized oxygen-containing stream. A venturi (34) is also disposed on the tank for receiving and combining the pressurized oxygen-containing stream with recirculated water from the tank to form a combined injection stream (36) of pressurized water which is super-saturated with oxygen, and which is then injected into the treatement water contained within the tank. As the tank is maintained at a pressure lower than that of the injection stream, the pressurized oxygen comes out of solution in tiny bubbles preferentially about particles of solid waste to entrain and provide supplemental floatation thereto. The result is to substantially oxidize any oxidizable material contained within the tank. The treated water is then removed by suitable means from the tank from the second chamber thereof.

Title: High-speed reproduction facility for audio programs
IPC: G11B31/00
Filed: 1988-10-14
Abstract: Method and apparatus for high-speed reproduction 
of a customized group of audio programs on a slave 
medium enables the reproduction of musical recordings 
at a point-of-sale terminal. Master programs are 
prerecorded by a Dolby ADM (adaptive delta modulated) 
technique to condense their "information" content and 
permit higher data throughput during high-speed 
reproduction. In a "premastering" process to make 
encoded masters, a special multiplexer board provides 
interfacing between Dolby ADM digital audio data and a 
conventional data processing system. The multiplexer 
board performs computer-like data blocking and also 
writes a unique sync code directly in the data block. 
The data processing system also catalogs and edits the 
blocked digital audio; places encrypted catalog, 
pricing, and other indicia in the data file 
representing the music; and sends the data file to a 
conventional 16-bit PCM file writer for making encoded 
CD music ROMS which contain the ADM data representing 
the encoded audio program. A high-speed reproduction 
device, under control of a desk top personal computer, 
extracts timing and ADM data from the CD music ROM at 
high speed and controls high-speed tape drives to 
compile selected recordings on a single cassette tape 
in a form compatible with Dolby B noise reduction.

Title: A wall coupling
IPC: B65D55/16
Filed: 1989-04-18
Abstract: A wall coupling restrains adjacent walls 2 and 3 from displacement over each other. The two walls have co-incident apertures 12 and 16. A flexible moulded plastics retaining strip 5 is carried by the wall 2 on its side remote from the wall 3. The strip 5 overlies the aperture 12 and has an end 8 which is secured relative to the wall 2 and an end 7 which is slidable along tracks on the wall 2 in a direction towards and from the end 8. A mid-length region 6 of the strip 5 between its ends 7 and 8 has integral hinges 13 to 15 so that during displacement of the strip end 7 towards the end 8, the region 6 doubles to project through the apertures 12 and 16 and thereby couple the walls 2 and 3 to restrain them from relative displacement.   Stop/catch means can be provided to temporarily retain the strip end 7 in a position where the mid-length region 6 of the strip is in either a folded or an unfolded condition. The invention is suitable for coupling a container lid which carries the retaining strip 5 to a wall of a container body.

Title: Optical clock system for computers
IPC: H04L7/00
Filed: 1990-04-20
Abstract: An optical clock system for high-performance computing 
systems uses unique methods of clock generation, delay 
timing, and electrical clock conversion to eliminate 
clock skew due to passive circuit elements. There is 
provided a direct optical connection to active devices 
in the computing system thereby eliminating the 
transmission of electrical clock signals through 
passive transmission elements. The optical clock 
system eliminates several stages of clock drivers and, 
as a result, is capable of reducing clock skew due to 
active circuit skew as well. In one embodiment, an 
optical pulse timing generator (10) produces ultrashort 
pulses which are equally divided by an 1-by-N splitter 
(16) into N optical fibers (18), where N depends on 
the number of clock signals required. Each fiber has a 
different length, resulting in different propagation 
times for the optical pulses. The light from each of 
the N fibers are again split into M fibers by N 1-by-M 
splitters (20), where M depends upon the number of 
distribution points for the clock. The NxM fibers are 
regrouped to form a bundle of N fibers, and these M 
fiber bundles are then coupled to each module (22) 
where the delayed optical signals are converted into 
the appropriate electrical clock signals.
