Title: Preservation of radioactive, toxic or infectious material
Inventor: HEUGEL GUENTER
IPC: B65D33/38
Filed: 1976-02-13
Abstract: Gas-tightly closable deformable bag has a closable outlet pipe via which the gas in the bag can be extracted.  The outlet pipe may be a hose suction which can be sealed with a stopper, and is pref. attached to the bag by welding or adhesion.  Pref. a filter assembly is mounted on it which remains within the bag, or means for connecting a filter assembly is mounted outside the bag.Even when the bag is full and welded up or adhered, it gas content can be removed to prevent infected, contaminated or toxically polluted gas or air from reaching the environment directly, or at least not suddenly, in case of damage to the bag.
Patent CH-684202-A5 (CH)
Title: Roof covering and structural element with solar cells
Inventor: REAL MARKUS
IPC: H02S40/36
Filed: 1991-07-11
Abstract: The structural elements (6) with solar cells bear directly on a roof substructure and engage in a positively locking manner into a transverse lathing arrangement (49). The same transverse lathing arrangement serves also for the positioning and securing of the other roofing elements, e.g. roofing tiles (2). Along with the adjacent roofing elements (2) and/or structural elements (6), the structural elements (6) form the roof covering. In the region of the structural elements (6), no roofing elements (2) are necessary, as a result of which a simple structure is possible. Each of the structural elements (6) is composed of a carrier panel with the solar cells and of a two-part frame which encloses the carrier panel. Connection boxes (48) and connecting cables (49) for the electric connections are arranged on the underside of the structural elements (6). <IMAGE>

Patent CH-660765-A5 (CH)
Inventor: STOYKE REINHARD
IPC: B44B7/00
Filed: 1986-07-08
Abstract: Markings have to be applied to the surface (41) of a mineral fibre web (38), said markings being arranged transversely to its length or to its direction of movement. For this, a cylinder (1) is provided with peripheral heating zones, in the form of heating rods (26), corresponding in shape and position to the markings to be applied, said cylinder (1) rotating at a speed whereby the rods (26), or marking ribs (30) provided on the latter, effect the rolling essentially without any slippage on the surface (41) of the mineral fibre web (38). The heating rods (26) or marking strips (30) are made of metal and are electrically heated, by an internal tubular heating element (31), to such a temperature that when contact is made with the surface (41) of the mineral fibre web (38) a flat decomposition zone (43) is created which corresponds to the contour of the marking strips (30), in which zone the binder of the mineral fibre web (38) is decomposed and by changing colour produces the optically visible marking line. The cylinder (1) can be driven either by a d.c. motor synchronously with the line speed of the mineral fibre web (38), or it can also be driven by entrainment with the surface (41) of the mineral fibre web (38).

Title: Connection between face mask and gas bottle - is hollow needle with screw connection and drive for piercing membrane on mask
Inventor: MOSCA TENNA GIOVANNI
IPC: A62B18/08
Filed: 1987-08-04
Abstract: To enable the weaver of a face mask (19) to breathe a protective gas, a liq. gas container (23) is connected to the mouthpiece (18) without risk of contamination. Projecting from the container is a tubular shell with an externally threaded bush (3) on its end, which is screwed into a nut (2) on the mouthpiece. Also supported by the shell is a hollow needle (37) which is forced through sealing elements to discharge the gas into the mouthpiece. The needle carries a square-threaded nut (35) which rotates inside an internally threaded part (29) of the shell so that the pointed tip of the needle firstly pierces a thin membrane at the front of the bush, then pierces a thicker membrane (5) inside the nut. The gas is then discharged through holes (38) at the  tip of the needle. ADVANTAGE - The wearer of the mask can breathe safely for long periods of time.

Title: Automatic mixed-product weighing-test check-out for loads on shopping trolleys in fully self-service markets
Inventor: DEILE MARIE-LOUISE
IPC: G07G1/00
Filed: 1993-04-03
Abstract: All shopping trolleys (E) in self-service market centres are equipped with a preprinted blank bill form. Each article has a doubly affixed detachable product code label. Before each article is loaded into the product space of the shopping trolley, the customer sticks the duplicate of the product code label to the blank bill form. By means of the identified product code, the electronic operative unit of the weighing-test till point (IP) makes the comparison between the test weight and the actual weight of the product assortment and its total product price. If the weighing test is positive, payment of the displayed purchase price is accepted. The weighing-test till point opens.

Title: Process for the production of a chicken pox virus preparation
Inventor: HILLEMAN MAURICE RALPH
IPC: A61K39/25
Filed: 1975-05-16
Abstract: A live, attenuated, cell-free chicken pox virus preparation is produced by cultivating the virulent virus in a tissue culture preparation. Used as tissue culture preparation are human or animal diploid cells or primary cells derived from monkeys. The cultivation is carried out by several passages at 30 - 38 DEG C. The attenuated virus is separated from the cell residues with ultrasound treatment in the presence of a stabilizer. A chicken pox virus preparation produced in this way can be employed as antigen in a chicken pox vaccine which induces in the human body an antibody response without causing clinical manifestations of chicken pox.

Patent CH-657231-A5 (CH)
Title: Thermally stabilised superconductor
Inventor: KWASNITZA KURT DR
IPC: H01F6/06
Filed: 1981-10-28
Abstract: The invention relates to engineering superconductors, for example NbTi or Nb3Sn multifilament superconductors and cables (for relatively high currents) composed of the latter. The object is to protect these conductors against thermal faults and impermissible temperature increases in the temperature range of about 2-25 K by adding materials having particularly high specific heat. To be regarded as such faults are friction during conductor movement or cracks occurring in the impregnating material (epoxy resin) of a superconducting magnet. Heat pulses are, however, also unavoidable during rapid changes in the magnetic field applied to the superconductor. In this connection, it has to be remembered that the materials making up a superconductor have very low values of specific heat (order of magnitude 10<-3> Ws/cm<3>.K) in the vicinity of the temperature of liquid helium. For this type of stabilisation, materials are proposed which, on the one hand, have values of specific heat which are higher by 1-2 orders of magnitude at the operating temperature of liquid helium as a result of phase changes, for example from the antiferromagnetic to the paramagnetic state, than those superconductors themselves which are important from an engineering point of view. In this connection see Figure 1. On the other hand, the materials we considered (these are intermetallic compounds of the rare earths with other elements (for example NdSn3 or PrCu2)) have, because of their metallic nature, a good thermal conductivity which makes it possible to absorb the heat in the stabilising material even during brief faults. <IMAGE>

Filed: 1969-12-04
Granted: 1971-09-10
Abstract: Flash evaporation desalination unti for sea-water comprises a number of evaporation/condensation chambers and a degasser for the in-coming sea-water. The degasser is also incorporated in the last chamber (at a low temp.) and this operates in independent extraction of the incondensable products contained in the sea-water.
