Title: Steerable trailers
Inventor: MITCHELL GEORGE WALLACE
IPC: B62D13/06
Filed: 1996-07-24
Abstract: A multiple axle trailer consists of a main chassis which is articulated to a tractor unit and is rotatably mounted on a sub-chassis 1 about an axis 21. The rotation of the main chassis on the sub-chassis 1 causes links 18, pivotally connected at ends 19 to a steering mounting on the main chassis, to steer the front and rear trailer wheels through bell cranks 15, track rods 11 and steering arms 10. The steering mounting is movable to shift the ends 19 from one side of the median longitudinal axis 9 to the other to reverse the direction in which each wheel is steered for a given direction of relative rotation between the two chassis, required when the tractor/trailer combination is reversed. Other embodiments have one link 18 and a link interconnecting the two bell cranks 15 (Fig. 6) or links directly connected to the steering arms with no bell cranks (Fig. 7).

Patent GB-2318594-A (GB)
Title: Firestopping system for building cavities
Inventor: KERNAGHAN JOHN VICTOR
IPC: E04B1/94
Filed: 1996-10-23
Abstract: A concealed cavity firestopping system uses a preformed plastic sack (6) which can be shaped to fill the voids or cavities common in the fabric of most buildings which unless firestopped will allow fire spread through those cavities. The sack is custom made for each void or cavity (2) and once in place, is filled with fire resisting/intumescent foam which expands within the sack to totally fill the void or cavity. Once full the foam is allowed to escape the 'sack' via specially positioned holes around its perimeter 7 so as to form a bond/seal with the internal surrounding structure. During a fire, the 'sack' melts away leaving the cured fire resisting barrier in place.

Title: Mineral insulated electric heating elements
Inventor: JOHNSON OLIVER SANDERS
IPC: H05B3/48
Filed: 1997-08-18
Abstract: The electrical breakdown strength of mineral insulated electrical heating elements, which are comprised of a thin walled metal tube containing one or more elongate electrical resistance element assemblies, insulated from one another and from the metal tube by a matrix consisting of powdered mineral insulation and a gas, in which the electrical breakdown strength of the heating elements is increased, or by increasing the electrical strength of the gas phase of the matrix. This increase in the strength of the gas phase is brought about by increasing the pressure of the gas or by using a gas of higher intrinsic electrical strength. The former may be achieved by presurising the element. During filling or by including a gas evolving material in the sealed element, release being achieved by heating.

Title: Deforming cylindrical bodies
Inventor: GOITISOLO JOSE ANTONIO NABARAN
IPC: B21H3/04
Filed: 1997-10-22
Abstract: Cylindrical bodies such as aluminium cans are deformed to a predetermined configuration by means of tools acting in partnership. One tool is provideed with a relief formation and another has a resiliently deformable outer surface. The tools move about the cylindrical body 1 in partnership, one internally of the cylinder and the other externally of the cylinder such that the relief formation tool 14 presses into and deforms the cylinder material causing corresponding deformation of the resiliently deformable forming surface of the other tool 16. The technique is particilarly suited to producing threaded necks and the like for aluminium cans particularly to avoid damage to internal protective coatings applied to the can.

Title: Preparing samples for gas chromatography
Inventor: GERSTEL EBERHARD
IPC: G01N1/22
Filed: 1997-12-08
Abstract: A sampling 1 tube used to transfer samples to a GC system comprises a conical portion 4 containing an adsorbing agent 6, the tapered end of the conical section being in communication with a narrower bore section 5 which is free of the adsorbing agent. The diameters of the regions 3 and 5 of the tube are such that the flow rate of gas passing to the tapered conical section is equal to that at the tube inlet 3. Gas or liquid samples are fed to the tube in the direction of the conical section, i.e. through the inlet 3, so that test sample is trapped by the adsorbing agent 6. The sample loaded tube is then typically flushed with a drying gas fed through the tube inlet 3 to remove the liquid phase from the sample then the sample is desorbed by e.g. by passing a carrier gas through the tube, the carrier gas being supplied at the end 2 of the narrow bore section. Desorption may be in a thermal desorption device connected by a transfer capillary to the GC.

Title: Flow control device
Inventor: ZWART KLAAS JOHANNES
IPC: E21B34/10
Filed: 1998-11-20
Abstract: A resealable downhole flow control device (10) comprises a tubular body (12) for mounting on a tubular string and defining a flow passage (32, including port 36 and flow area around the free end of flow sleeve 48) between the body bore (18) and the body exterior. A metal to metal seal arrangement defined by first and second sealing surfaces (38, 39) which when they are in sealing contact close the flow passage (32). The sealing surfaces (38, 39) are urged together by spring (26). Separation of the sealing surfaces (38, 39) is caused by pressure differences between the interior and exterior of the device (10). This forces fluid to flow through a tortuous restricted path (58) into volume (56) and the piston area (54), the retractable sleeve (30) then slides towards end connection (16) slowly opening the seal. The resultant flow area (A) between the sealing surfaces is larger than the smallest flow area defined by the stated flow passage.

Patent GB-2335431-A (GB)
Title: Acoustical products and coatings therefor
Inventor: PAPE JAMES D
IPC: E04B1/86
Filed: 1996-11-07
Abstract: The invention provides products with a plain, nonperforated, surface. The products comprise a fibreboard substrate (with or without a laminated porous nonwoven scrim) and a painted surface. The painted surface decorates or finishes the board and remains acoustically transparent to retain the sound absorption properties of the fibreboard prior to painting. The fibreboard substrate is porous or modified with hole perforations to cause it to be a good sound absorber. If the fibreboard substrate is sufficiently porous without hole perforations, then sprayable, high solids, paint can be applied directly to the substrate to provide a porous coating. If hole perforations are used to improve the sound absorption properties of the substrate, then a porous, nonwoven scrim is attached and painted using the high solids paint. The painted scrim must be sufficiently optically opaque to hide the holes punched in the board, yet sufficiently open to render it acoustically transparent.

Title: Generating telephone comfort noise during silence in a packetized system
Inventor: WOOD ROBERT GEOFFREY
IPC: G10L19/012
Filed: 1999-05-28
Abstract: A transmitter is adapted to halt the transmission of voice packets after a predetermined time period following the detection of silence. The receiver is provided with a circular buffer 1 for storing incoming voice packets, the buffer having a size such that it becomes filled with silence or empty packets received from the transmitter during the predetermined period before transmission is halted. A control block 5 compares the addresses of the buffer input pointer 2 and the buffer output pointer 3 and, in the event that the addresses are the same, determines that silence has occurred. When silence is detected at the receiver, a random number generator 4 loads numbers into the output pointer resulting in a random sequence of the silence packets being sent to the telephone receiver as comfort noise. This helps prevent background clicks or noise spikes becoming repetitive.
