Abstract: Disclosed are novel means of enhancing efficacy of pancreatic islet transplantation through administration of regenerative T cells concurrently with modification of the local microenvironment to provide a tolerogenic and angiogenic milieu. In one embodiment, the liver microenvironment is prepared for receipt of pancreatic islets by administration of tolerogenic cells antigen presenting cells, subsequently followed by administration of T cells and/or T regulatory cells conditioned by regenerative cells, and finally pancreatic islets are administered. In other embodiments devices are provided which allow for concurrent administration of pancreatic islets together with T cells and/or T regulatory cells that have been conditioned with regenerative cells. In another embodiment, the administration of T cells and/or T regulatory cells conditioned by regenerative cells is after administration of therapeutic pancreatic islets.

Abstract: A wayside railway sensor package is provided to detect railway wheels for the purposes of assessing the speed and direction of a train in order to align any measured characteristic on said moving train with the proper vehicle. The stand-alone package is easily installed in the web of the rail using standard tools. When used in combination with recent processing techniques, the package can be used to replace one or more components or subsystems on all common wayside detectors while also providing enhanced capabilities and improved reliability. The package also contains sensors that provide data used for assessing additional rail, wheel, and vehicle conditions directly.

Abstract: A support device for use in supporting an animal during the carrying out of a magnetic resonance imaging (MRI) scan includes a main bed (A) on which the body of an animal can be supported and an auxiliary unit (J), which is movable relative to the main bed (A) and on which structures are provided for supporting a limb of the animal on the main bed (A) while an MRI scan is carried out on the limb.

Abstract: An apparatus for splitting stones and blocks comprises means (5A, 6A) for supporting a stone or block while it is subject to a splitting operation, a unit which includes an upper blade (1) for engaging an upper surface of the stone or block and a lower blade (10) for engaging a lower surface of the stone or block, means (5) for effecting movement of the upper blade (1) downwardly towards the lower blade (10), a base (1A, 3A), and resilient support means (11) acting between the base (1A, 3A) and the unit.

Abstract: An electric implement lift system for mower cutting units may include an electric motor having a rotatable output shaft with a pivot bracket mounted thereto, a lift link or a pair of lift links, each lift link having a first end connected to the pivot bracket and a second end connected to a lift arm, the output shaft rotatable in a first direction to raise the mower cutting unit and in a second direction to lower the mower cutting unit. The output shaft may be rotatable in the first direction to move the cutting unit to a top/center position and rotatable further in the first direction to move the cutting unit to a raised/transport position.

Abstract: A neutron monitoring instrument, principally of the survey type, is provided with an inner neutron detector(s) enclosed in a layer of neutron attenuating material and one or more outer neutron detectors provided on the attenuating layer and enclosed in a layer of neutron moderating material. The inner detector(s) monitor neutrons in the 100 KeV to 15 MeV energy range, with the outer detectors monitoring neutrons in the thermal to 100 KeV range. Sensitivity across the spectrum and evenness of response are improved compared with the prior art to give better close equivalence determinations.

Abstract: A splitter for splitting stone, concrete, wood and the like comprising a frame (21), a first splitter blade (24) moveable relative to the frame (21), a second splitter blade (23), and hydraulically actuatable means (26, 27) for pulling the first splitter blade (24) towards the second splitter blade (23) to effect said splitting. The hydraulically actuatable means (26, 27) preferably acts on end portions of the first blade (24) to provide increased leverage for the splitting operation. The first blade (24) is preferably provided with centering means (32, 28, 29, 31) for urging the first blade (24) into a central position when it has been moved to one side during the splitting operation.

Abstract: A panel for a padded enclosure, such as a large animal treatment room in veterinary practices, has a resilient body with an impermeable skin or a plastics coating (5) over one face (1) and the edges (2). The edges have longitudinal grooves (4) and the coating follows them so that when two panels are placed edge to edge there is a concealed void. These edges (2) are adhered and sealed together when lining the enclosure, coated faces innermost, but the sealant/adhesive (6) does not fill the voids. These voids compensate for the stiffness that would be inherent in a plain coated edge and make the cushioning effect of the padding substantially uniform.

Abstract: The prevailing tension in an elongate strand, such as a textile yarn, is instantaneously measured, even at very low levels of tension and at fine incremental changes in tension, by a tension measuring apparatus utilizing a pair of fixed contact arms spaced from one another to define a strand contact line therebetween and an intermediate cantilevered sensing arm disposed at an equal spacing from each fixed contact arm and at a lateral spacing from the stand contact line. The fixed contact arms and the sensing arm are contacted with the strand simultaneously at the same common lateral side of the strand to cause the strand to deflect from the strand contact line at equivalent strand break angles between the respective strand contact points on the fixed contact arms and on the sensing arm.

Abstract: A survey system employs a ground-based extendible mast so that survey instruments, such as cameras, mounted at the top of the mast can attain heights comparable to those of low-level aerial photography. The mast is mounted on a base structure that houses a self-contained power plant, including an internal combustion engine, electric batteries and means for compressing fluid and storing it in a pressurized state. The mast may be telescopic and also tiltable, and the instrument pack at the top may be controlled from ground level to move to selected attitudes, e.g. to pan and tilt.Simpler versions are described, omitting the power plant and adjustable entirely manually, and one system is carried by an operator rather than being ground based.

Abstract: In conventional processes for separating metals by selective precipitation, the precipitate is frequently in an amorphous form, eg a slime, which is difficult to filter, wash and handle generally. In the present process mixed solutions and/or sols of the metals are mixed with a suitable soluble organic polymer to form a viscous mixture. The latter is formed into discrete entities, e.g. drops, which are contacted with a reagent which converts each drop to a gelled entity containing at least one of the metals as a precipitate.In one form of the process, the same chemical reagent also serves to dissolve the other metal present in the initial drops. The metals are then easily separated by separating the gelled drops from the reagent. In another form, the reagent includes two different chemical reagents which contact the drop simultaneously, one to precipitate one metal in the gelled drops and the other to dissolve the other metal.
