  • Publication number: 20210403222
    Abstract: A package containing nuts and suitable for microwave heating is described herein. The package is configured to heat the nuts and provide an aroma reminiscent of traditional, freshly-roasted nuts. The freshly-roasted nut attributes include an aroma, temperature, texture and taste, which are reproduced with the microwave package. The package preferably, though not necessarily, incorporates one or more susceptors in order to provide additional heating, such as conductive heating, to the nuts. The package also preferably includes a sufficient headspace to allow for the aromas to develop.

  • Patent number: 6693947
    Abstract: A batch process for an electric arc furnace (1) to manufacture steel (10) includes the steps of providing an empty furnace having a bottom (14) and sides (16) and electrodes (2, 3); adding molten metal to the empty furnace; adding other necessary ingredients through charge openings (26); applying current to provide an arc (4) and supplying oxygen through an oxygen lance (6) to react and melt the contents of the furnace and form a top slag (9) and bottom molten metal/steel (10); and stopping the reaction and pouring out all the slag through a slag tap (5) and molten metal tap (32) to provide an empty furnace for the next batch run.

  • Patent number: 6447477
    Abstract: A guide (100) is provided for biopsy and microtherapy which includes an introducer cannula (120) defining a lumen (125) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening (124) in communication with the lumen (125) adjacent the first end (121) of the cannula (120). The invention also includes a solid tip (130) having an anatomically distal end (131) secured to the first end (121) of the cannula (120) and a proximal end (132) configured to pierce tissue. A ramp (135) is disposed within the cannula (120) at an end (136) of the lateral opening (124) adjacent the first end (121) of the cannula (120). The ramp (135) is inclined toward the lateral opening (124), whereby the item will be deflected through the lateral opening (124) as it advances within the lumen (125) and exits the cannula (120). In some embodiments, the item is a biopsy needle, ablation means or a radiopharmaceutical seed.

  • Patent number: 6228049
    Abstract: An introducer guide 15 for introducing medical items into an internal tissue of a patient is provided. The guide 15 includes a cannula 20 defining a lumen sized to receive the item and a lateral opening 24. A ramp is disposed within the lumen adjacent and inclined toward the lateral opening 24. A hub 40′ is attached to the second end 22 of the cannula 20. The hub 40′ includes a gripping portion 41′ configured to be held when inserting and positioning the introducer 15. The gripping portion 41′ has a length lgp sufficient for gripping and a tactile indicator 44 disposed along substantially the entire length lgp of the gripping portion 41 on the hub 40′. The indicator 44 has a fixed angular relationship with the lateral opening 24. The invention also includes methods for obtaining a biopsy sample and methods for treating lesions.
