Title: Variable data rate channels for digital networks
Inventor: BURREN JOHN WALTER
IPC: H04J3/16
Filed: 1992-05-27
Granted: 1995-05-17
Abstract: Communication channels provided by the Integrated Services Digital Network (ISDN) usually carry 64 Kbits/sec in each direction and are therefore unsuitable for data traffic at higher rates. This difficulty can be overcome by assembling ISDN channels to form channels having a higher bit rate. However problems arise, for example, in the transmission of data packets where the bit-rate required changes frequently and therefore the number of channels grouped together must be changed often. These problems are tackled as now described. Data packets are received from local area networks by a computer 13 and stored in queue areas 174 to 178 of a store area 173. The queue areas correspond to groups of ISDN channels which are combined to form high bit rate channels, known as slots and U-channels, respectively. The computer 13 assembles data from the queue areas into an ISDN frame held by a frame buffer 172 using an appropriate number of slots in the frame for each U-channel. ISDN frames are passed to conventional ISDN circuits in a terminal 11 which uses the ISDN to transmit to a similar terminal. On reception ISDN frames are passed to a frame store 182 and then slots in frames are passed to packet assembly buffers 184 to 188, one for each U-channel, before being passed to users as data packets. When a new slot is to be added to a U-channel without interrupting data in the existing slots, synchronisation signals are sent in the new slot and a system of flags is used to establish when data is to be sent in the new channel. When the bit-rate of a U-channel is to be reduced by removing a slot, a distinctive closing sequence is sent in that channel which on reception is an indication that no further data will be sent in that slot. <IMAGE>

Title: Motion compensated image interpolation
Inventor: SAUNDERS NICHOLAS IAN
IPC: H04N7/36
Filed: 1993-06-24
Granted: 1997-07-16
Abstract: The motion compensated temporal interpolator is capable of determining when a background scene is covered or uncovered by a foreground object by projecting motion vectors determined for the output field onto temporally adjacent input fields (i/p1, i/p2) and detecting the number of times each input pixel is used as a source for the output pixel - covering corresponds to multiple pixel use in the following field while uncovering corresponds to multiple pixel use in the preceding field. The motion vectors for output pixels in a covered area can then be corrected by forward projecting vectors from the preceding frame pair whereas output pixels in an uncovered area are corrected by backward projecting vectors from the following pair.   <IMAGE>

Title: Composition and method for enhancing transport across biological membranes
Inventor: ROTHBARD JONATHAN B
IPC: A61K47/48
Filed: 1998-05-21
Granted: 2000-11-08
Abstract: Methods and compositions for transporting drugs and macromolecules across biological membranes are disclosed. In one embodiment, the invention pertains to a method for enhancing transport of a selected compound across a biological membrane, wherein a biological membrane is contacted with a conjugate containing a biologically active agent that is covalently attached to a transport polymer. In a preferred embodiment, the polymer consists of from 6 to 25 subunits, at least 50% of which contain a guanidino or amidino sidechain moiety. The polymer is effective to impart to the attached agent a rate of trans-membrane transport across a biological membrane that is greater than the rate of trans-membrane transport of the agent in non-conjugated form.

Filed: 1980-01-21
Granted: 1990-11-22
Abstract: Frequency modulator consists of a vortex chamber with circular cross-section and a tangential inlet branch. This generates a vortex motion in the flowing medium. The outlet from this is on the top and forms a compression chamber of smaller dia. Arranged around this are a series of smaller outlet chambers with tangential entry from the compression chamber. Fluid then forms a series of small vortices in these chambers. Outlet chambers are arranged around the top of the large inlet vortex chamber. Used to produce sonic and ultra-sonic beams which can then be used to analyse aerosol suspensions. Allows control of the frequency merely by absorbing the flow without any significant change in the resistance to flow.

Title: Equipment for paint drying after application and for the removal of solvents used with the paint
Inventor: DE MARCHI UGO
IPC: F26B/
Filed: 1990-02-12
Granted: 1993-09-03
Abstract: The equipment concerned refers to equipment for paint drying after application and for the removal of solvents used with the paint. The equipment includes, in succession, inside a tunnel fitted with a lengthwise conveyor belt, multiple ventilated passivation chambers and multiple drying chambers with infrared ray catalytic beds. The catalytic beds of each drying chamber are supplied with combustible gases and an airflow, which since it is taken from the passivation area or from the previous drying chamber, contains the evaporated solvents from the paint. A fan extracts the burnt gases from the last drying chamber and discharges them into the atmosphere. Upstream from the tunnel, corresponding to where the paint is applied, there is a flue with one or more gas catalytic beds inside onto which the air polluted by the solvents is conveyed continuously and which is then burnt.

Abstract: A chuck for a hand held power tool has a plastic sleeve (20) which is screwed onto a plastic body (22). The sleeve (20) has a conical end to receive a lining (54) of hard metal. Three hard metal jaws (44) are forced against the shank of the tool (48) as the sleeve (20) is screwed further onto the body (22) without the need for any special key.

Title: Contact lens autoclave steriliser for home use - with vapour-tight capsule holding lenses and sterilising solution
IPC: A61L/
Filed: 1978-08-18
Granted: 1985-12-02
Abstract: An autoclave steriliser for contact lenses comprises a capsule for housing the lenses and providing a vapour-tight chamber in which a sterilising solution is placed. The capsule is received in a housing which includes a thermally conductive heat well. A heater is in abuting, heat transfer contact with the well. A thermostat contacts the well at the opposite side to the heater and this controls the heater to deactivate it when the temperature rises to a set level above the boiling point of the sterilizing solution. A pivoted cover coverlies the well and this may be locked in position by a latch associated with a bimetallic strip contacting the well at a position intermediate the heater and thermostat. This ensures locking of the cover before the temperature of the sterilizing solution reaches a dangerous level.
