Abstract: A magnetic endoscopic system including a wireless endoscope. The wireless endoscope includes one or more cameras and one or more lights for viewing internal portions of a body. The wireless endoscope further includes one or more magnets. The magnetic endoscopic system also includes a positioner externally positioned against the body for moving the wireless endoscope when positioned entirely or partially within the portions of the body. The positioner includes at least one magnet for attracting the one or more magnets and magnetically moving the wireless endoscope.

Abstract: A nasal dilator and bougie is disclosed. The dilator includes, for example, an elongated member terminating in an end and a slidable member having a terminal end movable to the end of the elongated member in a first position. A dilation portion at the end of the elongated member has a first diameter and a second diameter greater than the first diameter when the slidable member is in the first position. An actuator can move the slidable member.

Abstract: An elastomer-modified unsaturated polymer comprises an unsaturated polyester or vinyl ester polymer modified by a low molecular weight elastomer. The elastomer has terminal groups provided by an epoxy resin which render it compatible with the unsaturated polymer. These elastomer-modified unsaturated polymers are useful for providing resin compositions which include a cross-linking agent for the unsaturated polymer. The elastomer is soluble in the resin composition, which is curable to provide an unsaturated resin matrix having particles of the modifying elastomer dispersed therein.

Abstract: A photo-initiator system of a polyester resin is disclosed which consists of an oxime carbonate of a vicinal diketone (I), a photo-reducible dye (II) and an amine (III). This system is capable of polymerizing and curing unsaturated polyester resins by irradiation with visible light to provide coatings, adhesives, castings and fibre reinforced composites.The formulae of the ingredients of the system are ##STR1## where R' and R" are independently alkyl, aryl or aralkyl (R' preferably being CH.sub.3 and R" C.sub.2 H.sub.5) ##STR2## wherein X=Br or I on at least 2 positionsY=H, Br, IZ=H, COOM, COOR wherein R=C.sub.1 -C.sub.5 alyl.M=H, K, Na, Li, NH.sub.4(there preferably being 4X substituents which are Br, and Z preferably being --COOM or --COOR), and wherein also 4Y substituents may be present and preferably be I) and (III) ##STR3## wherein R.sub.1 is H, alkyl, hydroxy-substituted alkyl, aryl or aralkyl. R.sub.2 is independently alkyl, hydroxyl substituted alkyl, aryl or aralkyl.
