Patent GB-2286363-A (GB)
Title: Producing limited fire hazard epoxide glass laminates
Inventor: HOGAN NEIL
IPC: B29B15/12
Filed: 1995-02-10
Abstract: A resin composition is prepared comprising an epoxide resin and hydrated alumina and optionally one or more additives such as magnesium carbonate hydrate, calcium carbonate hydrate, magnesium hydroxide or calcium silicate. A glass fibre web is led from a supply reel through a bath of the resin composition to impregnate the web with the resin composition. The web is then delivered through a drying tower, partially polymerising the resin to produce a dry handleable prepreg sheet. A number of prepreg sheets are stacked and delivered to a laminate press. In the laminate press, the stack is compressed for a preset time period to form an epoxide glass laminate sheet. The sheet is then trimmed to any desired size. <IMAGE>

Title: Coil tubing hydraulic jar device
Inventor: HAILEY CHARLES DAVID
IPC: E21B31/113
Filed: 1995-06-05
Abstract: A hydraulic jar device for use in connection to coil tubing consists of an elongate tube having an upper hammer sub, a guide cylinder and a hydraulic cylinder 12 with central restrictor 58. A lower sub connects to the bottom end of the hydraulic cylinder. The sliding interior components are an upper mandrel secured to an anvil sub which, in turn, is fastened to an axial plunger 44, all of which are slidable down within the elongate tube. A guide means prevents relative rotation between the mandrel and the elongate tube. A metering ring 56 retained on the plunger 44 interacts with the central restrictor 58 of the hydraulic cylinder on both upward and downward movement of the plunger 44 to effect both up and down jars which occur when the mandrel strikes the hammer sub on the down stroke, and when the anvil sub strikes the hammer sub bottom on the up stroke. <IMAGE>

Title: Plastics fencing system
Inventor: PENNY STEPHEN MAURICE
IPC: E04H17/16
Filed: 1995-09-13
Abstract: A fencing system is manufactured from modified plastic to allow the provision of an interlocking arrangement without the need for mechanical fixings; the life expectancy of the fence is maximised and maintenance is minimised. The main components are the post shown at figure 2 and rails and connecting blocks which have dovetail ends slidable into the groove in the post. The fencing system will not be liable to degradation from moisture attack from below ground. Due to the interlocking features of the system no failure is anticipated at the connection between post and rails. The nature of the material used will allow some flexibility during wind loading and as such freedom from snapping off at ground level.

Title: Adaptive power allocation for Multicarrier Transmission System
Inventor: BAE HEE-MOON
IPC: H04J13/00
Filed: 1996-01-31
Abstract: The transmission power used at the transmitting end for each sub-channel is controlled in response to the SNR for each sub-channel measured at the receiving end. Firstly, a higher power is allocated for channels having a higher SNR. Secondly, if that allocated power exceeds a maximum transmission power threshold for the channel, then the allocated power is reduced to the maximum threshold. Thirdly, if the SNR of any sub-channel below the maximum power threshold is negative, then the power for that sub-channel is recalculated. The apparatus includes a carrier transmission portion (600) for transmitting the data signal with the allocated power levels at the transmitting end, and receiving the signal at the receiving end, and a power controlling portion (602) for calculating the transmission power level. The data transmission efficiency is increased and the power is not allocated near sub-channels having negative SNR values, to thereby prevent power loss. This can be used in an asymmetric digital subscriber line (ADSL) for multimedia transmission.

Title: Preventing blockage of the outlet of a bag
Inventor: FAIRBANK HARRY MICHAEL
IPC: B65D88/16
Filed: 1996-02-14
Abstract: A plastics bag 11 for containing a flowable material includes an outlet port 10 and means to restrict the movement of at least a portion of a wall of the bag during discharge of the contents. This prevents the bag from blocking the outlet port during discharge. The means may comprise an annular plastics reinforcing member 14 which is welded to the plastics material of the bag. Alternatively, or in addition, a discharge device 15 which co-operates with the port 13 may be provided, including an end plate 16 and holes 15d for the passage of flowable material into the device. The reinforcing member 14 restricts the bag from collapsing inwardly and the arrangement of the end plate 16 and holes 15d restricting the wall opposite the outlet port from being sucked into the device during discharge of flowable material. As a result, it is found that a high percentage of the volume of liquid in the bag can be discharged therefrom.

Title: Delay time measuring method and pulse generator for measuring delay time for use in said measuring method
Inventor: BABA TADAHIKO
IPC: G01R31/3193
Filed: 1997-01-24
Abstract: A method for accurately measuring the delay time of a signal path (10) constituted by an IC of a CMOS structure in a state which is the same as, or approximate to, the actual operation state. A loop oscillation circuit including the signal path (10) is constittuted, and is brought into a loop oscillation state by feeding a start pulse ST to the circuit. An interpolation pulse P 1 having a frequency which is the same as, or approximate to, the frequency of the pulse signal propagated with the signal path is in an actual operation state, is inserted, this interpolation pulse P 1 and the loop oscillation signal P LO are fed to the signal path, and the signal path is brought into the substantially same temperature state as that of the actual operation state. The cycle of the loop oscillation signal P LO is measured under this state so as to measure the delay time of the signal path.

Title: Bale density control system for agricultural balers
Inventor: LIPPENS CHRISTIAAN ANDRE CAMIE
IPC: A01F15/08
Filed: 1997-10-07
Abstract: An agricultural baler (10) comprising a baling chamber (18) and means (20) for loading successive charges of crop material therein also comprises means (94, 87) for automatically adjusting the cross section of the baling chamber (18) to the load experienced by the plunger (24) during compression of these charges and thus controlling the density of the bales formed therein. The density control system further comprises means associated with the actuator means (87, 31) of the baling chamber for precluding adjustment of the cross section when no new charge of crop material has been introduced into the baling chamber (18). These means comprise a sensor (60) sensing the passage of such charge along a wall portion (36) of the baling chamber (18) and a by-pass valve (82) which controls the pressure of hydraulic oil provided to the actuator means (87, 31). Thus is prevented that the cross section of the baling chamber (18) is reduced further when the baler (10) is turned on headlands and no new charges of crop material are inserted into the baler (10).

Filed: 1996-09-20
Abstract: The device (2) which is the subject of the invention is provided with a deck (4) for the location of any form of goods, such as packages, while goods, persons in wheelchairs and herein referred to generally as goods. Said deck (4) is connected to a movement mechanism on a support assembly (8) for raising or lowering of the deck (4) relative to the support assembly (8) and the said deck (4) and/or movement mechanism are provided with wheels or rollers (16) such that when the deck (4) and/or movement assembly are in a substantially lowered position the wheels (16) contact the surface (40) to allow the device (2) to be moved therealong and when the deck (4) and/or movement mechanism are raised, the wheels (16) leave the surface (40)) and are replaced with the support assembly (8) contacting the surface (40) which prevents movement of the device (2) along the surface (40) and thereby provides a secure base. The invention therefore provides an adaptable flexible and relatively simple movement device (2) and does not require a braking system as in conventional devices thereby reducing the risk to safety caused by failure.
