Title: Callus-specific promoters
Inventor: DRAPER JOHN
IPC: C12N5/10
Filed: 1992-09-02
Abstract: A marker gene for use in the genetic transformation of plants is driven by a promoter which is capable of acting as a callus-specific promoter, for example in monocotyledonous plants. A suitable promoter naturally drives the expression of a gene encoding a predicted 16.92 kDa protein after wounding and/or callus formation in Asparagus officinalis or an equivalent protein in other members of Liliaceae or Amaryllidaceae. A preferred embodiment is designated the AoPR1 promoter. Under the control of a promoter of the invention, the marker gene (which may for example be an antibiotic- or herbicide-resistance gene) is expressed strongly in wounded tissues and cells and cultured explants, but not constitutively throughout the whole plant. Such promoters may also be used to drive expression of genes in plant tissue culture.

Title: Production of chimeric antibodies - a combinatorial approach
Inventor: HOOGENBOOM HENDRICUS R J M
IPC: C07K19/00
Filed: 1992-09-23
Abstract: Methods are disclosed which may be used for the production of antibodies, or antibody fragments, which have the same binding specificity as a parent antibody but which have increased human characteristics. Humanised an-tibodies may be obtained by chain shuffling, perhaps using phage display technology. In one embodiment, a polypep-tide comprising a heavy or light chain variable domain of a non-human antibody specific for an antigen of interest is combined with a repertoire of human complementary (light or heavy) chain variable domains. Hybrid pairings which are specific for the antigen of interest are selected. Human chains from the selected pairings may then be combined with a repertoire of human complementary variable do-trains (heavy or light) and humanised antibody polypeptide dimers can then be selected for binding specificity for anti-gen. The methods may be combined with CDR-imprinting.      In another embodiment, component part of an antigen-binding site of a non-human antibody known to bind a par-ticular antigen is combined with a repertoire of component parts of an antigen-binding site of human antibody, forming a library of antibody polypeptide dimers with antigen-bind-ing sites. Hybrids selected from this library may be used in a second humanising shuffling step, or may already be of suf-ficient human character to be of value, perhaps after some modification to increase human character still further.

Title: Weighted trophy base
Inventor: STAGL PETER M
IPC: A47G33/00
Filed: 1994-06-30
Abstract: ABSTRACT OF THE DISCLOSURE An improved weighted  base for a trophy, includes a cup-shaped shell having a platform for supporting portions of the trophy above the base.  A cover having a surface for resting on a table, shelf and the like is connected to the shell to define a hollow interior cavity.  A fill hole in the cover provides access to the cavity and a funnel extends from the fill  hole to provide a flow path into the cavity.  A cross section of the flow path in the funnel is larger proximate the funnel outlet end than proximate the fill hole.  Hardened filler in the base, which filler was introduced to the cavity in fluid form via the fill hole and funnel,  increases  the weight of the base.   A vent opening connects the cavity with the external environment during filling of the base.  Narrowing the funnel near the fill hole reduces loss of filler should the filler fracture in the base.

Abstract: A linked strip comprises many interlocking synthetic spirals (10) where each winding has a flat shank (12) and a sharp bend (11). The bends of one spiral interlock like a zip with the bends (11', 11") of neighbouring spirals to form channels for securing wires (14) so to connect the spirals. Here, flat wires (15) in the spirals for reduction of linked strip air permeability are tilted w.r.t. the strip plane. A process for strip prodn. entails inter-positioning the spiral windings (11) to overlap, insertion of the securing wires (14) in the channels so formed transverse to the strip path, and insertion of the flat wires (15) into the spirals. Here, it is just after this sequence that the linked strip is thermally locked. The flat wire (15) in the spiral (10) interior is wider than the smallest distance between the two adjacent spirals, runs above one and under the other spiral securing wire (14), is clamped between the spiral inner surface and the outer surfaces of the two adjacent spirals and tapers to a point along its lengthwise edge where the edge angle is less than the wire tilt. The spirals can be formed in the cross-sectional shape of a parallelogram with different diagonals where the securing wires (14) are laid in the angles of the longer diagonal and the flat wires (15) in those of the shorter. The flat wires shrink in their longitudinal direction and expand transversely when thermal fixing occurs and so are inserted with an extra length so that after thermal fixing their length coincides with the breadth of the spiral linked ribbon.

Abstract: A process for converting hydrogen sulfide which is contained in a gaseous feed stream to elemental sulfur and hy-drogen. The process comprises contacting said gaseous feed stream with a polar or-ganic solvent having an anthraquinone, and optionally a complexing agent, dissolved therein, reacting the hydrogen sulfide gas and anthraquinone to produce sulfur and an anthrahydroquinone in the solvent, and cat-alytically dehydrogenating the anthrahydro-quinone to anthraquinone and hydrogen. In accordance with the present invention, a rel-atively small quantity of water is added to a polar organic solvent thereby increasing the elemental sulfur which is precipitated and thus recovered. The addition of water prior to or during sulfur production also in-creases hydrogen product selectivity in the subsequent dehydrogenation of anthrahydro-quinone.

Title: An apparatus and method for reducing stress in the brace bar of a coriolis effect mass flow meter
Inventor: NORMEN DAVID FREDERICK
IPC: G01F1/84
Filed: 1994-07-20
Abstract: A Coriolis effect mass flow meter having a brace bar of improved flexibility which reduces the stress concentration in a brace bar as well as in areas of meter's flow tubes proximate the brace bar and flow tubes of the flow meter. A brace bar means is disclosed that has a void in an area between its holes that receive the flow tubes. This void increases the flexibility of the brace bar and shifts the concentration of operational and manufacturing induced stresses away from the braze joints between the brace bar and the flow tubes. The stresses are reduced and shifted away from the flow tubes to an area within the brace bar that is less critical to the overall life and reliability of the flow tubes. Meter sensitivity is improved due to enhanced flexibility of the present invention's brace bar in response to the motion induced by the Coriolis effect. Additional embodiments are disclosed which also provide increased flexibility of the brace bar while maintaining required rigidity to resist undesirable independent motion of the flow tubes.
