摘要:
A klystron has a hollow beam electron gun that has a circular planar electron emitting surface. A hollow electron beam is directed from the electron gun through a plurality of drift tubes, resonant chambers and magnetic fields to a collector. The hollow electron beam does not experience significant radial movement and can operate at a lower beam voltage which reduces the required length of the RF interaction circuit and lowers the risks of RF arcing.
摘要:
A heater element for formed components is disclosed, along with the final formed component itself. The heater element is produced by photochemically etching a suitable heater track pattern from porous metallised fabric such a nickel coated woven polyester. The heater element is located within a mould. Thermo-formable material is then applied to the mould and the final component is shaped according to the shape of the mould. The final component has a heater element located within it. The component may have microencapsulated agents for initiation by operation of the heater element. Furthermore, the final component may have one or more digital images printed onto the surface for the purposes of decoration or personalisation.
摘要:
Disclosed is a breathable heater element for a garment or for the lining of a garment such as an outdoor jacket, e.g. a waterproof jacket. The heater element is formed from porous metallised fabric such a nickel plated woven polyester fabric by photochemical etching of a suitable track pattern onto the metallised fabric. The formed heater element is then laminated into a lining. The material of the lining may be impregnated with microencapsulated functional chemicals such as fragrances, perfumes, antimicrobials or insect repellents. The microcapsules release their contents on activation due to heat generated by the heater element.
摘要:
A suture-material-dispenser system for a supply of suture material includes the supply of such material and a housing which defines a cavity for containing the supply. The housing includes a top region that has an opening formed in it and an antimicrobial plug within the opening. The plug seals the cavity and has a suture-material-dispensing port to allow dispensing of suture material therethrough. The antimicrobial plug comprises silver, which is durable, non-reactive, cost-effective and has antimicrobial properties.
摘要:
System, including apparatus and methods, for positioning medical material in living tissue using hollow elements that are formed unitarily from a synthetic bioabsorbable material.
摘要:
A shipping and storage container for surgical sutures, with or without an attached needle comprising a non-cellulosic, hydrophobic material folded to define a container, the container defining a first cavity adapted for receiving and encasing a suture material. The non-cellulosic, hydrophobic material is preferably a polymeric material such as polypropylene.
摘要:
System, including apparatus and methods, for positioning medical material in living tissue using hollow elements that are formed unitarily from a synthetic bioabsorbable material. The hollow elements are optionally filled with a core material and a heat shrink process is performed so that the hollow elements are tightened around the core material.
摘要:
Liquid, particularly leaked oil or other hydrophobic liquid, is detected by a sensor. This preferably has a hydrophobic membrane (G) that takes up the oil selectively, a radiation source (A) that beams radiation at an interface between the membrane (G) and a window (F), and a radiation detector (H) that receives radiation resulting from interaction (such as reflection, scattering or fluorescence) of the input radiation with the liquid-containing membrane (G). The detector may employ a spectrofluorimeter (H) whose output can be used to characterise the liquid.
