Abstract: A nebulizer comprises a gas exit, at least one outlet adjacent to the gas exit, and a deflector for deflecting a stream of gas issuing from the gas exit over the at least one outlet for drawing a substance to be atomized from it, and for atomizing the substance in the gas. The deflector defines first and second profiles, and the atomizer has an atomizing configuration in which the first profile of the deflector lies in the stream of gas for atomization, and non-atomizing configuration in which the second profile of the deflector lies in the stream of gas without atomization of the substance.

Abstract: An atomizer for dispensing a powder or liquid product which is atomized by a stream of compressed air and further has either (1) means to prevent or stop the product from atomizing in response to a positive pressure in the atomizer or (2) a secondary reservoir located between the product reservoir and a product outlet from which the product is atomized, said secondary reservoir is in fluid connection with a second chamber, the second chamber being operable in response to a positive pressure in the atomizer to drive fluid from the secondary reservoir.

Abstract: Printing plates are formed from a layer of photo polymerizable resin by a process and assembly which includes a negative of the image or images to be formed in the printing plate. The negative is placed on a lower glass support plate and a bank of lights is disposed below the lower glass support plate. A cover film is laid down on the negative, and a very thin layer of resin, called a cap resin, is deposited on the cover film. A layer of the resin to be cross-linked is deposited on the cap resin layer, and the cross-linked resin layer is covered with a polyester sheet, on the top of which an upper glass plate is lowered. The cap resin layer and the cross-linked resin layer are both laid down on the lower glass plate assembly by meas of a carriage assembly that traverses over the lower glass plate assembly, and which carries the cross-linking resin and cap resin reservoir. The thickness of the cross-linked resin layer varies widely, while the thickness of the cap resin layer is narrowly confined.

Abstract: The invention is a method for detecting the presence of bacteria in a sample. The method of the invention utilizes the steps of (a) admixing a fluorescent conjugate with a sample to be tested for the presence of bacteria in the sample, wherein a moiety of the fluorescent conjugate is metabolized to release the fluorescent moiety of the fluorescent conjugate; (b) inducing fluorescence of the fluorescent conjugate and the fluorescent moiety of the metabolized fluorescent conjugate at 325-345 nm; (c) simultaneously detecting the fluorescence of the fluorescent conjugate at 370-380 nm and the fluorescent moiety of the metabolized fluorescent conjugate at 445-480 nm; and (d) correlating the detected fluorescence of the fluorescent conjugate and the fluorescent moiety of the metabolized fluorescent conjugate to the presence of bacteria in the sample.

Abstract: An apparatus for administering a fluid medicament to a patient in a gas for inhalation and for calculating the dosage administered to the patient comprising a holding member (1) for temporarily holding the medicament and gas prior to inhalation, means for introducing a quantity of the medicament into the holding chamber (1), a sensor (4) for detecting the introduction of the medicament into the holding chamber (1), detector means for detecting the rate of flow of gas inhaled by a patient from the holding chamber (1) and calculation means (25, 27, 29, 30, 31) operably connected to the sensor (4) and to the detector means for calculating the amount of medicament received by a patient.

Abstract: A tear-open bag is made of non-tearable synthetic resin and comprises a front side and back side formed from a single web of synthetic resin. The sides of the web are heat sealed together to form an end-to-end seam in the bag. The ends of the bag are heat sealed together, thereby forming a completely moisture resistant heat-sealed bag. One end closure of the bag is provided with a tear-propagating slit which can be readily manipulated by an adult to tear off a corner of the bag and thereby form a pour spout for dispensing the contents of the bag in a controlled manner. The slit is not readily or easily used by a child to open the bag, thereby rendering the bag child-resistant.

Abstract: Printing plates are formed from a layer of photo polymerizable resin by a process and assembly which includes a back masking negative placed over the non-printing side of the resin layer. A connective substrate is positioned between the back mask negative and the resin layer. A negative of the image or images to be formed on the printing plate is positioned on the side of the resin layer which is to form the printing surface of the plate. Both sides of the resin layer are exposed to UV light, and the back mask negative serves to allow hardening of the resin only in the areas of the resin layer where printing surfaces are located. Thus, a plurality of isolated printing surfaces may be formed on the plate, which printing surfaces are connected together by the connective substrate. In this manner, a photo polymerized floor need not be produced on the printing plates, allowing increased resin recovery after the plate has been formed.

Abstract: The nonpolymerized portion of the resin on a photopolymerizable resin is recovered from a printing plate by squeezing the liquid resin off of the plate with the doctor roller. The plate is mounted on a drum and the drum is caused to rotate in a predetermined direction while the doctor roller is pushed against the surface of the plate. The liquid resin falls from the plate into a collection tray. The collection tray is divided into opposite adjacent resin repository sections, with a separate doctor roller being disposed above each repository section of the collection tray. Incompatible resins can be squeezed into the respective repository sections of the collection tray by the respective rollers by selectively rotating the drum in one direction or the other, and by selectively engaging the plate with one of the rollers while keeping the other roller away from the plate.
