  • Patent number: 11952814
    Abstract: A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

  • Publication number: 20220215245
    Abstract: A system and a method for training non-parametric Machine Learning (ML) model instances in a collaborative manner is disclosed. A non-parametric ML model instance is trained at each of a plurality of data processing nodes to obtain a plurality of non-parametric ML model instances. Each non-parametric ML model instance developed at each data processing node is shared with each of remaining data processing nodes of the plurality of data processing nodes. Each non-parametric ML model instance is processed through a trainable parametric combinator to generate a composite model at each of the plurality of data processing nodes. The composite model is trained at each of the plurality of data processing nodes, over the respective local dataset, using Swarm learning to obtain trained composite models.

  • Patent number: 7232979
    Abstract: A microwave oven liner 11 is an injection moulding having a roof 12, a floor 14, a back 15 and two sides 16. The moulding is of food grade polypropylene, such that the liner can be washed in a commercial dishwasher. The liner is sized to be a sliding fit in a microwave oven. The roof is shorter 17 at the front than the floor to allow air circulation. Further, the roof is apertured, also for air circulation, with a series of small c. 4 mm bores 18 registering with the roof aperture 8. A lip 19 is provided across the front of the floor to retain split liquid. The external corners 20 are chamfered to clear the silicone seal 9 for instance. The floor has regularly pitched, 2 mm high ridges 21 running front to back. The ridges allow circulation of air beneath a container of food being heated in the oven having the liner.

  • Patent number: 6835267
    Abstract: An automotive quality paint coat (44) is laminated to the exterior surface of a molded plastic car body member or panel (118). In one embodiment, the paint coat (44) includes an exterior clear coat (45) above a color coat (46). During processing, the clear coat (45) and color coat (46) are each coated on a temporary flexible casting sheet 42) and dried. A high gloss surface is transferred to the clear coat (45) from the casting sheet (42). The paint coat (44) is then transferred from the casting sheet (42) to a thin, semi-flexible thermoformable plastic backing sheet (72) by dry paint transfer-laminating techniques. The resulting laminate (70) is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate (116) is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article.

  • Patent number: 6590084
    Abstract: The present invention relates to a process for preparing 9-deoxo-9(Z)-hydroxyiminoerythromycin A corresponding to formula (I) below: from 9-deoxo-9(E)-hydroxyiminoerythromycin A by reaction with a base in water or in a mixture of water/solvent of dialkyl ketone type capable of forming a crystallizable solvate with the desired 9(Z)-oxime; acidification of the reaction mixture to a pH of between 9 and 11; addition to the said mixture of an organic solvent; optionally concentration under vacuum of the resulting organic phase; and isolation of the desired 9(Z)-erythromycin oxime.

  • Patent number: 6562953
    Abstract: The invention relates to a process for preparing compound of general formula I by reductive amination of the corresponding (4″)-carbonyl derivative, characterized in that it comprises: placing the said (4″)-carbonyl derivative in contact with at least one nitrogenous reagent and a Lewis acid under conditions that are favourable for converting the 4″ carbonyl function, reducing the resulting mixture using a reducing agent, and optionally deprotecting the hydroxyl function in position 2′, to give the expected compound of general formula I.

  • Patent number: 6482931
    Abstract: The invention provides a process for the preparation of 9-deoxo-8a-aza-8a-homoerythromycin A and of its 8a-alkylated derivatives from 9-deoxo-9(Z)-hydroxyiminoerythromycin A via a stereospecific Beckmann rearrangement in a reaction mixture using pyridine as main solvent, resulting in imidate intermediates which are not isolated from said mixture and which are employed directly in a reduction stage using a sufficient amount of borohydride, after extraction of the pyridine with a hydrocarbon which is miscible with the latter and in which said imidates are insoluble. The compound V can be directly N-alkylated at the 8a-position using an aldehyde without being isolated from the reduction mixture.
