  • Patent number: 5270061
    Abstract: A dual composition hard coated chewing gum is provided which exhibits improved long-term shelf stability under storage conditions involving constant exposure to the moisture contained in the atmosphere. The dual composition hard coated chewing gum is ideally suited for pellet chewing gum having pellet shapes which cannot easily be protected from atmospheric moisture by packaging. The dual composition hard coated chewing gum has a gum center which includes a gum base, a bulk portion, and one or more flavoring agents. The dual composition hard coated chewing gum also has an outer coating which includes layers which contain from about 50 to about 100% xylitol; and layers which contain from about 50 to about 100% hydrogenated isomaltulose. A method of preparing the dual composition hard coated chewing gum is also provided.

  • Patent number: 5267494
    Abstract: The present disclosure provides an improved bottle opener incorporated on a key having a head and a body. The head has a U-shaped cutout at a downward angle in the range of about 30.degree. to about 60.degree. with fulcrum and lifting edges. The cutout has a width of about -5% to about +8% that of the thickness of a bottle cap. The fulcrum edge has a radius at the cutout opening that engages the top of a bottle cap without puncturing it. The lifting edge passes beneath the rim of the bottle cap, and the body is long enough to provide leverage sufficient to remove the bottle cap.

  • Patent number: 5268301
    Abstract: A method for filtration assaying a particulate sample labelled with low-energy radioactive isotopes measurable by scintillation counting. The method aspect of the invention includes the step of providing a sample comprising sample particles labelled with low-energy radioactive isotopes in a liquid medium. Scintillant particles are added to the liquid medium. The sample is then filtered with a filter medium adapted to retain the sample particles and the particles of scintillant, such that after filtration the sample particles are each surrounded by scintillant. A photodetector is then used to detect light emitted by the scintillant on the filter medium.

  • Patent number: 5267907
    Abstract: A control system for a continuously variable transmission reduces the noise generated as a result of the use of an articulated belt for connecting the first and second variable pulleys. The control system dithers the ratio set point in order to prevent a cyclic repetition of the forces between the belt and the pulleys. This reduces the amplitude of noise peaks generated at discrete frequencies by operation of the transmission resulting in a decrease in the level of perceived noise.

  • Patent number: 5266996
    Abstract: A recording apparatus has both a copier function and a fax printing function. The recording apparatus is provided with a photoconductive member, an original table on which an original is placed, and a scanner for scanning the original placed on the original table to project an image of the original onto the photoconductive member so that an electrostatic latent image may be formed on the photoconductive member. An optical print head is provided for forming an electrostatic latent image on the photoconductive member based on an electric signal. Accordingly, the recording apparatus has two modes, a copy mode in which an electrostatic latent image is formed by an operation of the scanner and a print mode in which an electrostatic latent image is formed by an operation of the optical print head. A plurality of sensors are provided for detecting the operation of the scanner, which is controlled by a controller in each of the copy mode and the print mode.

  • Patent number: 5264915
    Abstract: In an interferential measurement device for at least one direction of measurement for measuring the relative position of objects, the collimated light beam bundle emanating from a light source is split into three diffraction beams in the at least one direction of measurement at a scanning grid. These three diffraction beams are divided into eight diffraction beams at a cross grid of a material measure and in turn come to interference at a scanning grid under renewed diffraction. The resultant diffraction beams fall on detectors for the generation of measured positional values for the at least one direction of measurement. The cross grid of the scale extends diagonally to the at least one direction of measurement and has an effective grid constant de in the direction of measurement, which agrees with the grid constant d of the scanning grid.

  • Patent number: 5262307
    Abstract: The present invention relates to a procedure for hydrolyzing keratin, in which procedure the solid keratin ingredient is (a) pretreated with an aqueous solution containing sulphite ions to form denatured keratin, and (b) hydrolyzed with the aid of a proteolytic enzyme to form keratin hydrolysate. The pretreatment is carried out at about 60.degree. to 100.degree. C. and it lasts about 10 minutes to 4 hours. The hydrolysate thus obtained can be treated further for use as a fodder addition or to isolate oligopeptides for use in cosmetics.

  • Patent number: 5262851
    Abstract: A facsimile apparatus capable of processing the image information receiving from a particular transmitter in a mode different from the usual mode of processing image information receiving to distinguish the communication from the particular transmitter from those transmitted by others immediately. For example, the image information receiving from the particular transmitter is recorded on different kind of paper from usual image information recording paper, or recorded in different color from usual image information recording color, or the paper recorded the image information from particular transmitter is discharged onto different tray from the tray onto which usual image information recording paper is discharged.

  • Patent number: 5262828
    Abstract: An image forming apparatus accommodates a developing bias power unit for applying a bias voltage to a developing sleeve confronting a photosensitive member. The developing bias power unit includes a DC power source, an electricity storage element interposed between the DC power source and the developing sleeve, and a controller for on-off controlling the DC power source. When an output of the DC power source is activated, the electricity storage element is electrically charged by an output voltage of the DC power source, and a first voltage is applied to the developing sleeve. In contrast, when the output of the DC power source is deactivated, a second voltage of reverse polarity is applied to the developing sleeve by electric charge held in the electricity storage element.

  • Patent number: 5261931
    Abstract: SO.sub.3 flue gas-condition systems (10) provide a controlled flow of flue gas-conditioning agent such as SO.sub.3 into a boiler flue gas and its entrained particulate material ahead of an electrostatic precipitator (14). The systems (10) monitor the opacity of the stack effluent and precipitator power and operate to maintain a flow of SO.sub.3 -conditioning agent into the boiler flue gas to provide minimal opacity of the stack effluent. The systems operate at SO.sub.3 -conditioning agent flow rate corresponding to minimal opacity of the stack effluent and to eliminate corrections that may be due to transient operating conditions such as boiler upsets, precipitator rapping and the like. The systems include features providing improved conversion of SO.sub.2 into SO.sub.3, integrated assemblies to provide a flow of SO.sub.2 and sulfur dioxide conversion units adapted to convert SO.sub.2 into SO.sub.3 at a plurality of remote SO.sub.3 injection sites.

  • Patent number: 5261339
    Abstract: In a button-holder for a button-sewing machine, two clamp parts (8,9) for the button (7) are guided in a parallel guide holder (28) so as to be movable by a pneumatic cylinder (34) in opposite directions. The parallel guide holder (28) is swingable horizontally by a pneumatic cylinder (17) to displace the clamp parts (8,9) from a sewing position (A) to a resting position (B).Thus, the button-holder does not require adjustment for different sized buttons and the button can be inserted away from the sewing region.
