Title: Electromagnetic assembly
Inventor: BEYER WILFRIED
IPC: H01H50/46
Filed: 1993-12-23
Abstract: ABSTRACT OF THE DISCLOSURE        An electromagnetic assembly, for example for a relay, has a magnetic core surrounded by an electrical coil, and an armature closing the magnetic circuit of the electromagnetic assembly. The magnetic core is of the split pole type having a first pole and a second pole, the former being surrounded by a shading ring to produce a phase shift in the magnetic flux in the region of the poles when the electrical coil is energized. A step is provided in the first pole between the shading ring and the armature so that the flux density, and thus the magnetic force, between the first pole and the armature is in-creased.

Title: Magnetic joints between moulded parts e.g. for mannequins
Inventor: VIGNE PATRICK
IPC: A47F8/00
Filed: 1992-07-15
Abstract: There is disclosed a mannequin or form for displaying clothes accessories or other articles, comprising at least two parts (2, 4) which are separable at a respective joint to allow the mannequin or form to be dressed, the or each joint comprising a joint-surface (6,8) on each part, at least part of which joint-surfaces engage each other when the joint is assembled, magnetic material (14, 20) being contained in or behind both of the joint-surfaces, the magnetic material in at least one of the parts comprising, or being magnetised by, a permanent magnet (20) sufficient to hold the joint together in use. This arrangement is much simpler to assemble than the prior art arrangements. The two parts of the joint merely need to be brought into proximity and magnetic forces then draw them together. There is no necessity to rotate one part relative to the other, with a resultant reduction in the likelihood of damage to the clothes.
Patent CA-2116055-A1 (CA)
Inventor: HOLLANDER MILTON B
IPC: G12B9/02
Filed: 1994-02-21
Abstract: An encased electronic instrument of the type having a front panel bearing controls and visual displays that is clamped to the forward periphery of a box-like case,  is provided with a resiliently deformable  and  elastically  stretchable  identifying  shield surrounding and overlying the front panel, and extending a given distance rearwardly generally parallel to the outer surface of the instrument case.  The shield is preformed, with an outer peripheral band defining an open center having a shape slightly smaller than, but generally conforming to the outer shape of the front panel and the rearwardly extending outer surfaces immediately adjacent to the front panel. A first inwardly extending flange projects from the forward edges of the peripheral band in overlying relationship with the outer edges of the front panel of the instrument, and a second inwardly extending flange projects from the rearward edges of the peripheral band to enhance frictional engagement between the band and the underlying outer surfaces of the instrument.  The second inwardly extending flange may also serve to retain the shield on the front panel and to provide sealing between the panel and the case, by being clamped between the rear surface of the front panel and the forward edges of the side surface portions of the case, replacing the sealing gasket previously described as being used in the prior art.  The material from which the shield is formed is resiliently deformable and elastically stretchable, so that it can be  stretch-fitted  over the  front panel  of an  instrument  in peripheral elastically gripping relationship; the thickness of the body of the shield is selected so that the force of unintended impacts with the outer surface of the shield will be absorbed in part in the shield and will be transmitted in part to the abutting surface of a panel in which the instrument is mounted, and will also be transmitted, with reduced intensity, to the outer surface of the instrument. The shield also serves to provide convenient and ready  visual  differentiation  among  a  plurality  of  clustered instruments, as in a control board, through the use of distinctive colors which may be applied to the surface of the shield or which may be made an inherent part of the shield material.   Visual identification is further enhanced by molding distinctive words or symbols into a visible surface of the shield.

Title: Multimeric forms of human rhinovirus receptor protein
Inventor: GREVE JEFFREY M
IPC: C07K16/00
Filed: 1993-06-22
Abstract: The present invention relates to novel forms and configurations of intercellular adhesion molecule (ICAM) including multimeric configurations that effectively bind to human rhinovirus and can effectively reduce HRV infectivity. When in a multimeric configuration, preferably as dimers, these proteins display enhanced binding of HRV and are able to reduce HRV infectivity as well as the infectivity of other viruses known to bind to the "major" group human rhinovirus receptor (HRR). The multimerized proteins may also be used to block tICAM interaction with lymphocyte function-associated antigen-1 (LFA-1).

Title: Use of immobilized film reactor
Inventor: BISHOP DOLLOFF F
IPC: C02F3/30
Filed: 1993-03-24
Abstract: Biofilters (3) for treating contaminated air (5) use immobilized biofilms on filter support media to biodegrade sorbed volatile organic compounds (VOCs) and biotransform inorganic oxides to sulfur (SOx) and nitrogen (NOx) to residuals such as carbon dioxide, water and various acids (HCL, H2SO4, HNO3). The buffers in the trickling liquid (9) neutralize the acid. Some preferred support materials include pelletized solids, pelletized peat, pelletized compost, pelletized activated carbon, hydrogel beads, ceramics, and straight passage media such as extruded ceramics and extruded carbon. Pelletized supports and straight passage supports permit removal of excess biomass by hydraulic or chemical cleaning and minimize pressure loss. The biofilters are characterized by low pressure drop across the bed, good contact of influent gas with the biomass, and satisfactory biomass adherence to the support. The biofilters are easily cleaned of excess biomass or are self-cleaning.

Title: Synthesis of acetoglyceride fats
Inventor: PELLOSO TURIDDU A
IPC: A23L25/00
Filed: 1994-02-03
Abstract: Acetoglycerides are prepared in a solventless, single phase interesterification between triacetin and triglycerides bearing long C16 to C22 fatty acid residues by adding triglycerides bearing saturated C3 to C10 acid residues to the reaction mixture. The long acid residues may be hydrogenated before or after interesterification. In one embodiment, the C3 to C10 triglycerides are tripropionin, tributyrin, or mixtures of these; in another, these are triglycerides bearing C8 to C10 acid residues; and in a third, these are a mixture of tripropionin and/or tributyrin and C8 to C10 triglycerides. In preferred embodiments, the molar ratio of C16 to C22 triglycerides to triacetin and C3 to C10 triglycerides varies between 1:1 and 1:15, more narrowly between 1:3 and 1:12, and high temperature are employed. The process diminishes catalyst use, obviates the need for high shear mixing, shortens reaction times, and simplifies purification steps.
