Patent GB-2277546-A (GB)
Title: Inflatable packer assembly
Inventor: SNIDER PHILIP M
IPC: E21B33/127
Filed: 1992-10-15
Abstract: An inflatable packer assembly for use in a subterranean well bore to isolate an interval of the well bore and/or adjacent subterranean formation for treatment. The assembly comprises a hanger assembly (100), a fluid piston assembly (20) and at least one inflatable packer (120). As constructed and positioned in the well bore, the hanger assembly and fluid piston assembly are sufficiently distant from the interval to be treated to inhibit being stuck in the well bore. By lowering and raising the tubing or drill string from which the inflatable packer assembly suspended, the fluid piston assembly pumps well bore fluid into and from the packer to respectively inflate and deflate the packer. In this manner, the packer can be repeatedly inflated, deflated and repositioned within a well bore to treat successive intervals of the well bore. <IMAGE>

Title: Separator/folder bag machine
Inventor: HATCHELL PETER
IPC: B65H45/16
Filed: 1991-11-07
Abstract: A separator/folder apparatus 10 for separating individual sheets such as bags (22, Fig. 2) from a continuous web (12, Fig. 2) having transverse perforations formed therein and for folding the separated bags comprises a separator mechanism 32 and one or more fold stations 34, 36, 38. A slowdown mechanism comprising rollers 84, 86 driven by a motor 82 via a two-speed clutch mechanism 88 is positioned downstream of the final fold station 38 and before a starker. When the clutch is not engaged the rollers 84, 86 operate at a speed matching that of the bags through the separator/folder mechanism 28. An optic sensor 90 determines when a bag emerges from the final fold station and causes the clutch to be actuated when about one third of that bag remains to pass through the rollers 84, 86 thereby reducing their speed by approximately one third, so slowing the bags. The clutch 88 is disengaged after the bag has left the rollers 84, 86 for engagement of the rollers 84, 86 with the next bag. <IMAGE>

Title: Ligand binding variable domain (V-min) comprising a framework region with a cyclically permuted central beta barrel
Inventor: SLATER ANTHONY MICHAEL
IPC: C07K16/00
Filed: 1993-11-19
Abstract: The invention relates to ligand binding variable domains (V-mins) having structural rearrangement of the binding domain of immunoglobulins and other Ligand binding members of the immunoglobulin superfamily. The minimal elements necessary to retain good antigen binding affinity, the complementarity determining region (CDRs) and the central beta barrel structure for the Fv fragment, may be retained positioned appropriately in space by cyclic permutation of the central beta barrel structure and leaving the strands of the beta -barrel intact. The invention is also independently based on recognising that after cyclic permutation of the central beta barrel the framework region which supports the CDRs can be pared down through creation of novel linkages in the structure.

Title: Method and device for biochemical sensing
Inventor: HOLM-KENNEDY JAMES W
IPC: G01N27/414
Filed: 1992-10-20
Abstract: A method and application for detecting and measuring the presence of a binding target material (64) employs a semiconductor device (50) having a receptor-covered surface topgate (90), separated by a dielectric layer (58) from a substrate 56. Receptors 66 attached to this surface exhibit a chemical selectivity function. Binding occurs in a test solution (52) with charge associated with the target material (64) modulating at least one device characteristic. According to the present invention, measurement may occur under dry conditions, at a time and location different from when binding occurred, thus substantially eliminating problems associated with ionic shielding and reference electrodes, so prevalent with prior art wet measurement techniques. The device (50) includes backgate (62) to which a bias may be applied to restore the device's pre-binding characteristics which enhances the sensitivity of the device. Measurement of the restorative backgate bias provides a signal indicating binding of the desired target material. <IMAGE>

Title: Axle alignment systems
Inventor: GIBBONS RAYMOND MURRAY
IPC: G01B11/27
Filed: 1996-01-30
Abstract: An axle alignment system for alignment of a vehicle axle comprises two wheel clamps 20 for fitting to wheels 40 mounted on two ends of the axle, and a projector guide frame 10 for extending between the wheel clamps 20 to support a projector 41 such that it projects a beam perpendicularly to the axle. Each of the wheel clamps 20 comprises a longitudinal support member 27 adapted to extend perpendicularly to the axle and parallel to the ground to one side of the associated wheel 40, and two retractable contact arms 28 for engaging forward and rearward regions of the outer peripheral surface of the wheel 40. The two contact arms 28 are mounted on the support member 27 and are coupled together by a rack and pinion assembly 33 so that movement of one of the contact arms 28 in one direction results in corresponding movement of the other contact arm 28 in the opposite direction. The coupling together of the contact arms 28 in this manner ensures that the contact arms 28 of each wheel clamp 20 are symmetrically positioned relative to the axle when engaged with the outer wheel surface, and hence that the guide frame 10 is located such that the projector beam extends perpendicularly to the axle at all times.

Title: Bag discharge valve
Inventor: DEARING ROBERT
IPC: B65B51/00
Filed: 1996-07-01
Abstract: Control members 1 and 5 are arranged around the neck of the container. To restrict the flow of material from the container through the neck the control members 1 and 5 are urged together. Arms 2 of each control member 1 or 5 overlap and those arms are in the form of a 'v' such that as the members move towards each other the aperture between the control members is reduced with the aperture remaining a square. Accordingly the sides of the neck are reduced from more than one direction when the members are moved together in a single direction. When the neck is constricted it can be re-tied.

Title: Apparatus for the automatic transverse guidance of a vehicle along a traffic lane
Inventor: MEHRING STEFFI
IPC: G05D1/02
Filed: 1997-08-12
Abstract: Apparatus for the automatic transverse guidance of a vehicle along a traffic lane can be activated by means of an operating element 8 and the actual transverse-position value present at the activation instant serves as a desired transverse-position value for subsequent automatic transverse guidance operation. The element 8, a control lever, is moved forward to activate the automatic guidance and is movable in directions R and L to modify the vehicle position set initially. Large movements of the steering wheel at least temporarily deactivate the automatic guidance. This guidance is also switched off if the guiding signals e.g. from roadway markings, are inadequate. Under these conditions the reactivation has to be carried out manually. A visual indicator 7 and/or acoustic device 8 and/or haptically operating means signal the operating condition of the automatic guidance to the driver.
