  • Patent number: 11940188
    Abstract: A heat-pump system includes a compressor, an outdoor heating exchanger, an indoor heat exchanger, an expansion device, and a supplemental heater. The outdoor heat exchanger is in fluid communication with the compressor. The indoor heat exchanger is in fluid communication with the compressor. The expansion device is in fluid communication with the indoor and outdoor heat exchangers. The supplemental heater includes a burner and a working-fluid conduit. The burner is configured to burn a fuel and heat the working-fluid conduit. When the heat-pump system is operating in a heating mode, the indoor heat exchanger receives working fluid from the working-fluid conduit such that the working fluid flows from an outlet of the working-fluid conduit to an inlet of the indoor heat exchanger.

  • Patent number: 4961460
    Abstract: A mould (61) for metal casting has a mould cavity (62) and a sprue (63) communicating directly with the mould cavity (62) and located in the sprue (63) a sleeve (64) of refractory material having a cellular ceramic filter (65) fixed therein. The mould, which has no running system apart from the sprue, may be a sand mould or a metal die for producing castings by gravity or low pressure diecasting. The cellular ceramic filter may be a honeycomb type of structure having cells which extend between two outer surfaces of the filter or a structure having interconnecting cells such as a ceramic foam.

  • Patent number: 4694884
    Abstract: Molten metal is cast in a mould having a feeder cavity, which may be defined by a feeder sleeve, whose surface has a plurality of elongate projections or ribs spaced apart around its perimeter, the number and dimensions of the ribs being such that the volume of the feeder cavity is reduced by at least 20% compared to a feeder cavity of generally the same size and shape but without the ribs. Preferably the ribs extend substantially the full length of the inner surface of the feeder sleeve. The sleeve may have for example four ribs whose shape and size is such that the horizontal cross-section of the feeder cavity defined by the sleeve is cruciform. The ribs may be formed of material having an exothermic, an exothermic and heat-insulating, or a heat-insulating composition. The ribs enable a given casting to be fed from a smaller quantity of feeder metal than is usual.

  • Patent number: 4082390
    Abstract: A convertible tray cabinet that can be used as a salesman's case having a base and a lid for carrying a nested stack of jewelry trays, and which cabinet can then be converted to a jewelry case with sliding trays therein by removing the lid, discarding the base, placing the lid on its side and sliding said trays into said lid on a plurality of spaced-apart ribs on the inside surfaces of opposed sidewalls of said lid. The ribs are vertical when the lid is used as a salesman's case and are horizontal when the lid is placed on its side and used as a jewelry case.
