Title: Keeping a dispensable liq. sterile by enclosing in a valved dispenser - esp. for rinsing contact lenses
IPC: A61L12/00
Filed: 1977-05-02
Abstract: The process for maintaining a liq. not having antiseptic properties in a sterile state, in spite of repeated removal of some of the liq., comprises packing the liq. in a receiver defining an isolated aseptic area. The receiver has an exit orifice sealed by a valve which can be opened aseptically to allow liq. removal. The liq. and the receiver are sterilised before and/or after the packaging operation. The process is esp. used for liqs. used for cleaning contact lenses, partic. to isotonic solns. used in rinsing before replacing the lenses. The process enables the liqs. to be kept sterile in a simple manner. The use of ampoules contg. sterile liq. is hazardous from the aspect of glass particles.

Title: Two=stage shredding machine for fresh of frozen meat - with saw action guillotine for cutting slices which drop between thrust and cutting rollers
IPC: B26D3/18
Filed: 1977-07-25
Abstract: The two-stage meat cutting machine first cuts a portion into slices and then cuts each slice into strips, and is for fresh and frozen meat. The portion is initially fed by conveyor belt to a saw-action guillotine and the slices drop between inversely rotating cutting and thrust rollers. The guillotine blade may span horizontally between two rotating wheels, and is pinned in radially offset positions to each wheel face. Wheel rotation thus effects blade descent in combination with lateral motion. The action is suited to cutting frozen meat. The cutting wheel has continuous radial circumferential blades at regular axial intervals and cuts each slice into vertical strips. The trust has circumferential channels housing the blades, of the cutting wheel, and may have projecting nibs on the ribs to enhance the grip on frozen meat.

Title: Electroerosion machining system for cylindrical workpieces - has liq.-filled U=tube housing conductive barbs to monitor electrode position and maintain constant working voltage
Inventor: BRAUDEAU PIERRE
IPC: B23H7/28
Filed: 1977-09-01
Abstract: The machining system has the machining electrode (9) displaced automatically in the direction of the workpiece (3), so as to maintain a constant voltage between the electrode (9) and the workpiece. For machining the flanks of the workpiece (3), the electrode (9) is moved laterally with the amplitude automatically increased in successive steps. The electrode level is measured continuously via a U tube (21) filled with liquid with conducting barbs defining different levels. As the electrode reaches each level a different stage is initiated with each stage defined by a predetermined fixed value for the amplitude of lateral movement of the electrode (9). The machining system is used for cylindrical workpieces to provide increased protection against arcing.

Title: Accidental burns protector for HF incision creating generator - has support table metallic plate ensuring max. skin contact to reduce HF current density
IPC: A61B18/16
Filed: 1978-01-11
Abstract: The accidental burning protection system, for high frequency electrical incision generators, is of the type having an alarm control circuit fed from a low voltage d.c. source. The supply is fed via two return high frequency conductors to the electrical incision high frequency generators. The indifferent plate(21) is in contact with the patient(23) and is connected to earth via two conductors (11a, 11b) and the metallic mass(24) of the operating table. The indifferent plate has a metallic part of circular form surrounded by a rectangular part, the two parts not being electrically connected. This form of plate ensures that the maximum skin surface area of the patient is between its two parts. Thus the high frequency current density is reduced and thus so is the risk of burning.

Title: Automatic closing device for injection and sampling nozzles - with highly elastic sealing membrane with incised splits
Inventor: ZIMMERMANN KURT
IPC: A61M5/158
Filed: 1978-03-31
Abstract: Closing devide for the nozzles and small tubes of injection and blood-sampling appts. comprises a highly elastic membrane with a number of incised slits. In the rest position the membrane prevents an effusion of blood out of the nozzle inserted in a vein or from a tube remaining in a vein or of a catheter inserted in a blood vessel. The membrane with the slits, is fixed in the connecting sleeve by the piece made from a synthetic material. The part contains the receiving cone of the connecting pieces. The membrane is perforated by means of a system of slits e.g. one rectilinear slit in the middle, two slits in the form of a cross or three slits spaced 60 degrees from each other. The cone is pushed down and dilates the system of slits so that liq. can pass both ways. After removal of the cone the membrane relaxes and closes the slits sufficiently well when a tube or a catheter is being left in a vein. Device is suitable both for injections and for the removal of blood. There is no notable resistance in the circuit so blood samples can be taken without risk or damage to the red cells. The connecting pieces can be removed repeatedly, or withdrawn for a time while a bed is re-made, thus increasing the liberty of the patient.

Title: Disinfection of ion exchange resin - esp. for water softening by incorporation of small proportion of silvered resin
IPC: C08J3/20
Filed: 1978-04-06
Abstract: A filtering bed, partic. for softening, and made up from ion exchange resins and resin filtering materials, contains silvered material. 0.05-10, pref. 0.05-2, % of the synthetic resin is silvered. The silvered resin is made by charging the cationic or anionic exchange resin, or the synthetic resin filtering material, with simple or complex Ag ions. These are then converted in situ on the resin into metallic form by a reducing agent. The ion exchange beads are at least partially silvered on their internal surface. The silvered material serves for long term disinfection of water in filtering and softening installations. It leads to a total absence of germs in the bed without causing a significant reduction in exchange capacity. Silvering of the internal surface avoids abrasion losses. Germs are absent for up to 30 regeneration cycles, even if the entry water contains a high level. No silver can be detected in the eluate. Method }does not involve outlay for appts. nor an operator, and does not result in an ecological load. Appts. can be used in reverse osmosis installations.
