Title: Recombinant therapies for infection and hyperproliferative disorders
Inventor: GOLDSMITH MARK A
IPC: C12N15/54
Filed: 1991-07-18
Abstract: Host cells may be treated for an infection or a hyperproliferation disorder which is characterized by the presence, in the affected cells, of a trans-acting factor capable of regulating gene expression by inserting into the cells a polynucleotide construct having a cis-acting regulatory sequence which is regulated by the trans-acting factor and an effector gene which renders said cell susceptible to protection or destruction. For example, the cis-acting region may be homologous to the HIV tar region, and the effector gene may encode ricin A or HSV-1 thymidine kinase. Upon infection with HIV, the HIV tat protein activates the tar region, and induces transcription and expression of ricin A, resulting in cell death, or of HSV-1 tk, resulting in cell death upon treatment with dideoxynucleotide agents such as acyclovir and gancyclovir.

Title: Process for the purification of flue gases, and an apparatus for it
Inventor: POKKI TUOMO
IPC: B01D53/34
Filed: 1990-07-18
Abstract: The invention relates to a process for the purification of flue gases by feeding (7) limestone into the furnace (1) of a boiler, by separating (3) the dusts from the flue gases at a point after the furnace, by hydrogenating (14) the separated dust, which contains calcium oxide, by returning (12, 13) it to the flue-gas flow (11) at a point after the separation point but before the reaction zone (4), in which additional water or vapor is fed (15) into the dust-bearing flue gas, whereafter the dust which contains sulfated calcium hydroxide is separated (5) from the flue gases (6) thus purified.  According to the invention, the hot, dust-bearing flue gas coming from the furnace is divided in the separation zone (3) into a dust-poor main flow (11) and a dust-rich secondary flow (12), vapor or water mist (14) being fed into the secondary flow at a point at which the temperature of the secondary flow is 300-600 ·C.  The invention also relates to an apparatus, such as a cyclone, intended for use in this process and having nozzles (19) for feeding in steam or for atomizing water, and a connecting duct (12) between the separation device (3) and the flue-gas duct (11) for the purpose of making the activated dust-rich secondaryflow of flue gas to join the dust-poor main flow at a point after the cyclone (3).

IPC: B32B37/24
Filed: 1990-08-14
Abstract: In manufacture of a glass architectural panel (Fig 1) and aluminium foil (4) is bonded to a glass sheet (1) via a layer (2) of thermosetting polyester powder coating material, The powder is deposited (12) on the foil as the foil unrolls (11) and is melted (13) to provide a fused layer (2) which is then cooled (14) to solidify the layer and arrest progress of curing.      The solidified layer is sprayed (15) with a silane adhesion promoter, before being heated momentarily to enable the foil with its adhering and solidified, by uncured, layer, to be rolled up for storage (16).      The rolled foil is transferred nearer (17) to a float-glass production line (18), where, after being heated to allow it to be unrolled, it is fed onto a hot glass sheet (1) emerging from the line (18). The fused layer melts as it is brought down with the backing foil to contact the glass sheet (1) and fulfil the cure of the powder material so as to establish the bond. Instead of a single foil, several may be provided overlapping one another (Fig 3). Decorative effects can be obtained using different pigmentations of powder and partial metalization of the glass (Fig 4). The technique of interrupting the cure is applicable to provision of a glass window (Fig 5) and a glass laminate (Fig 6).

Title: Debris monitoring system
Inventor: PARKINSON JAMES R
IPC: G01R33/032
Filed: 1992-05-22
Abstract: A debris monitor apparatus and method and optical sensor apparatus and method that use the Faraday Effect to detect accumulation of debris on a magnetic probe. The probe contains a magnet and the optical sensor and is immersible in the fluid. As debris accumulates on the probe, the magnetic field changes. The optical sensor includes a magneto-optic material located within a portion of the changeable magnetic field, preferably near a node of the magnet. Means are provided to bi-directionally address the sensor magneto-optic material with linearly polarized light. Means are also provided to convert rotation of the light polarization angle into a modulation of the light's intensity. An electro-optic transducer converts the light intensity into electrical signals that indicate the quantity of debris accumulation on the probe, with a differentiated value of these signals with respect to time yielding rate of debris accumulation on the probe. Means are provided to calculate a ratio defined by the difference over sum of two bi-directionally transmitted pulses to provide a self-referenced output dependent only on the change in magnetic field caused by accumulation of debris on the probe. The changed magnetic field provides an inherent real-time memory of the accumulation of debris on the probe, which also permits multiplexed data collection.

Abstract: Apparatus for separating sequential batches of overlapping sheets includes a conveyor (4) of laterally spaced belts. Lift bars (13) secured to tubes are mounted for vertical positioning above the belts to raise the sheets from the conveyor and remove the moving force. The lift bars include spaced vacuum openings (12) coupled to the tube, which is coupled to a vacuum source. The openings are spaced for alignment with the trailing portions of sheets moving through the conveyor. A piston (15) in the tube selectively opens and closes the openings. The tubes are pivotally mounted at the downstream ends and the piston projects from the upstream end of the tube. A cam drive reciprocates the piston and simultaneously raises and lowers the tubes. The cam drive includes an inclined cam rod (40) on which a motor-driven rack (39) is slidably mounted. A link connects the rack to the outer end of the piston. The rack reciprocates on the cam rod and thereby pivots the vacuum tubes about the pivot unit and simultane-ously opens and closes the vacuum openings. The apparatus stops the leading sheets with successive sheets moving into increa-sing overlap. The leading end of a batch is stopped until the vacuum tubes and bars are lowered to place and release the sheets onto the conveyor belts in spaced relation to the preceding batch of sheets.  Wheels or other stop devices may be coupled to the top side of the sheets to assist the stopping action.
