Title: Biopolymer sponge tubes
Inventor: WATT PAUL WILLIAM
IPC: A61L31/00
Filed: 1997-10-03
Granted: 2002-06-26
Abstract: The invention provides biopolymer sponge tubes closed at one end for use in surgery. The preferred biopolymer is collagen. The biopolymer sponge tubes are prepared by forming an aqueous dispersion of the biopolymer, introducing the dispersion into tube-shaped moulds, freezing the dispersion in the moulds to form a shaped, aqueous dispersion, followed by freeze-drying the frozen aqueous dispersion. The tubes are fitted over endoscopic surgical staplers to provide improved sealing of stapled tissues, especially for air-tight sealing in lung resections. <IMAGE>

Granted: 1988-02-24
Abstract: The container is formed from cut and creased sheet material and is held inm erected condition by adhesive connecting portions of the sheet material. The container includes a microwave receptor material and is constructed so that the adhesive is located remote from the receptor so as to be least affected by the heat effects of the receptor material when the container and its contents are subjected to micro-wave heating. The container is provided with lines of weakening so that a section of the container can be torn back to expose the container contents for consumption. The torn back section may comprise a section of the top panel and a section of one of the top edge panels, the section of the top edge panel being defined by slits or cuts. A bottom edge panel overlaps the top edge panel containing the slits or cuts and thus provides a means of protecting the slits or cuts from accidental impact during erection and handling of the sealed container.

Inventor: FRANK FARNSWORTH
Filed: 1975-08-01
Granted: 1979-12-20
Abstract: The wheel rim is made to separate into two halves to ease tyre changing. The inside of the wheel rim is fitted with a special band (3) of plastic material which supports the wheel load if the tyre is deflated. This band is made in at least three sections bolted into a ring around the wheel rim. Each side of the ring is spaced from the sides of the wheel rim by inserts (4, 5) of plastic. The inserts are moulded on one side to lie along the profile of the tyre wall, while their inside edges are metal clad for a low friction contact with the ring. When they tyre is deflated and the ring supports the wheel load, some relative movement of the ring and wheel rim is possible.

Title: Method and apparatus for laser processing of transparent materials
Inventor: RAČIUKAITIS Gediminas
IPC: B23K26/00
Filed: 2016-12-20
Abstract: The invention relates to cutting or dicing and separation of a transparent substrate utilising laser radiation operating in a burst mode by forming a cutting/fracture plane consisting of the necessary number of laser-initiated damage areas. The proposed method includes a beam of the laser operating in the burst mode focused inside the transparent substrate and its translation at a certain speed concerning the laser beam and forming the required cutting/fracture plane consisting of an array of laser-initiated necessary number of damaged areas. In order to increase the processing efficiency and speed and improve the quality of the cutting/fracture plane, the laser beam is focused at the lower part of the transparent substrate and produce a partial area of laser-initiated damage, while simultaneously translation of the transparent material with respect to the laser beam in such a way that the partial damage areas formed by every burst of laser radiation are arranged side by side in such a way that the lower part of each partial damage area merges with the upper part of the partial damage region formed before it, forming an integral area of the damage directed towards the upper surface of the workpiece and inclined in the direction of the workpiece displacement. By further translation of the workpiece, the array of continuous laser initiated damage areas is formed and cutting/fracture plane is created.

Patent MX-174308-B (MX)
Inventor: THEILEN HERMANN
IPC: B22C1/22
Filed: 1991-09-03
Abstract: The invention relates to a process for coating granular mineral materials with synthetic resin. Minerals of this type, for example quartz sand, zircon sand, chrome ore sand, fireclay and corundum, are used in coated form in foundries as a moulding material (sand) for the production of shell moulds by the Croning process. The invention has the object of providing a hot-coating process which involves adding hot-liquid synthetic resin to the mineral material to be coated, but overcomes the disadvantages of the prior art by allowing rapid change of the synthetic resin types to be processed, allowing inherently reactive synthetic resins to be employed, and generally being more practicable and less complex. This object is achieved according to the invention in that the hot-liquid synthetic resin is only formed just before its addition to the mineral material, by melting solid synthetic resin.
