Filed: 1992-10-16
Abstract: In the prodn. of diamond films (I) on substrates (II) contg. Fe by CVD, (II) is first given a SiC barrier film (III). Pref. after deposition of (III), diamond seeds (IV) are formed by applying a negative bias, pref. of 0-300, esp. ca. 150 V, to (II), the (I) are deposited. The process gas contains CH4/H2 and TMS. The compsn. and conditions are: (i) for (III) deposition, 99.9-99.97 (vol.)% H2 + 0.003-0.1% TMS and 300-1100 deg.C; (ii) for (IV) formation, 80-99% H2 + 1.0-20% CH4 and 400-1000 deg.C; and (iii) for (I) deposition, 95-99/8% H2 + 0.2-0.5% CH4 and 400-1000 deg.C. The thickness of (II) and (I) is controlled by the deposition time. USE/ADVANTAGE - (I) are useful e.g. for making (II) resistant to wear and corrosion. (I) are extremely hard and rigid. Diamond seeds form readily on (III), allowing (I) with various thicknesses to be produced in a single stage.

Patent DE-4241233-A1 (DE)
Title: Portable air-cleaning apparatus for prams and persons suffering from allergies
Inventor: STRAUBINGER GERHARD
IPC: F24F8/117
Filed: 1992-12-08
Abstract: Children carried in prams are only very poorly protected against environmental influences (pollen, noxious dust particles, smoke, organic gases and vapours, asbestos, and the like). This also applies to people suffering from allergies and even entirely healthy people who wish to protect themselves, e.g. in road traffic or at the work place, from the previously described substances which are damaging to health. To date, this could only be achieved by a breathing mask, which constituted a great hindrance to breathing. Especially with children, a breathing mask is scarcely usable. The portable air-cleaning apparatus blows, by motor, the cleaned air through a filter directly into the vicinity of the air passages. The excess pressure resulting thereby keeps the polluted external air away. This effect is considerably intensified by a protective covering for the pram or by a face protector for adults. Areas of application: At the workplace, when walking, in hospitals, when insulating with glass wool, during demolition work of asbestos facades, in road traffic, in parking garages, during lacquering, varnishing and the like, in nursing homes, and animal breeding, or veterinary surgeons, for refuse collection, in catering, at large events, in joiners' workshops, during the pollen season, wherever dust and vapours arise.

Title: Home lift
Inventor: DOOSE VOLKER DIPL ING
IPC: B66B9/08
Filed: 1993-07-01
Abstract: The home lift is a lift arrangement conceived for overcoming differences in level. This is achieved by the simple mechanical transformation of the horizontal movement into a vertical movement. Located on a guide is a braked platform which is provided with a friction surface. By the horizontal movement of a wheelchair, the direction of movement along the guide is transformed into a vertical movement by means of friction surface, axles, rollers, the block-and-tackle principle and counterweights. The home lift is conceived for the up and down transport of, for example, wheelchairs and users, mothers and fathers with prams, and disabled and lame people who have to overcome a difference in level. It is a purely mechanical construction which is cost-effective compared with expensive electric lift systems and can be installed or retrofitted quickly and simply in the private and public sector.

Abstract: A container (1) for pumpable and free-flowing compounds (17) consists of a sack-like bag (3), arranged in a receiving frame (2), made of flexible, diffusion-tight plastic film and closed pressure-tightly. Starting from the lower region (9) of the bag (3) from its removal opening (10), which may also be the filling opening, is a line (11) to which a suction line (13) can be coupled. When removing compound (17) from the bag (3), the latter is raised progressively by a lifting device (16). As a result, and under the effect of the reduced pressure prevailing inside the bag (3), the bag (3) assumes a pear shape becoming increasingly slimmer. As a result, the compound (17) accumulates in the region of the mouth of the line (11), and the compound (17) can be completely removed from the bag (3) without difficulty and without air entrapments. In order to support the bag (3) laterally when it is full and to protect it, the receiving frame (2) has a wall (5). The base (4) of the receiving frame (2) has a central depression (20), from whose lowest point the line (11) starts. Air can be pumped out of the bag (3) by means of a valve (14) provided in the top of the bag (3) while the latter is being filled with compound (17) and/or while compound (17) is being removed. <IMAGE>

Title: Varicose vein ligation procedure
Inventor: FOSS PIERRE NICOLAS DR MED
IPC: A61B17/12
Filed: 1994-06-21
Abstract: Small implants with suitable applicators or injectors are inserted without opening the skin so as to compress the small surface vessels, using refined steel or elastic hypoallergenic plastics. Preferred implants come in vessel-compressing clip or clamp form, inserted in the skin together with the appropriate applicators or injectors. This method is suitable for the treatment of reticular varicose veins, telangiectasia, naevi flammei, haemangioma. The clips as inserted enclose the vessels to give a localised long-term tie-off, or again the implants can be so small as to be indiscernible. Assuming the vessels to be 2 mm at most in diameter, the clip crosspiece is at most 3 mm in width, using clip wires of a few tenths of mm in diameter. Implants injected from the surface must remain in place for a long period as compressive fibrous closure can take some time for full effect.
