Title: Thread dyeing method - leaving undyed section for hair implantation as a loop in tissue
Inventor: MILLER PAUL W
IPC: D06P3/30
Filed: 1979-03-27
Abstract: Synthetic hair-like threads, intended for implantation in human skin tissue, are dyed by winding the thread over a frame with a wide spreader in the centre. The thread is then coated by a liq. with a dispersed pigment which has a much greater dyeing power above a certain temp. The application of a hot gaseous medium above this temp. suffices to colour the exposed thread but not that in contact with the frame. The bare section is formed to a loop and used for implantation. This eliminates the risk of medical problems when synthetic dyes are in permanent contact wwith live human tissue. It also saves the formalities for approval of the use of every possible dye for this purpose by the Health Authorities.

Title: Automatic eye and spray protection screen for arc welding appts. - where arc voltage can only be applied to electrodes when window in screen is covered by safety glass
Inventor: PFANZELT JOSEF
IPC: A61F9/06
Filed: 1980-05-06
Abstract: A human welder is provided with a helmet or a hand-held shield with an open window. The open window is normally covered by a coloured safety glass held in position by two tension springs. The glass is also mounted on two arms, which are each attached to an armature located in a solenoid. The two solenoids are each fed with electricity by an electronic- or electromagnetic- switching circuit connected to a welding appts. feeding welding electrodes with either a.c. or d.c. When the appts. only provides a low voltage, e.g. an idling voltage, the solenoids are automatically operated to move the glass away from the window, so the welder can see the workpieces. But when the voltage is raised, e.g. to strike the arc, the current to the solenoids is cut off shortly before the voltage is increased, so the springs move the glass over the window. Complete protection for the human face and eyes from harmful radiation and weld spray.

Title: Spinning process - with fibre bundle passed through rotary abrasive device to provide sleeve of false-twisted, abraded fibres around carrier yarn
Inventor: FRYS LUDOVIC
IPC: D01H1/11
Filed: 1980-05-16
Abstract: Spinning of a twistless bundle of fibres is effected by passing the bundle over a mobile, roughened surface, in a direction transverse to the direction of movement of the bundle. The bundle is gripped upstream by feeding means, such as drafting rollers, and downstream by delivery rolers. The bundle is transformed by a temporary false twist applied to it, to a spun prod resembling a 'sleeve' or sheath of intermingled and crimped fibres. A carrier yarn may be introduced for the sleeve. Process requires a spinning device of small dimensions, and capable of very fast speeds. The spinning device is inexpensive and easy to handle, and produces high yields. Fancy yarns having a wide variety of effects may be created. In such a prod the individual twist inserted in the product is very low, thus providing a bulky effect.
