Abstract: Known processes for coating hollow bodies such as cans are problematical in terms of productivity and contamination caused by high rotational speeds of the application rolls due to lacquer splashes and lacquer mist. These problems are solved by means of a process and a device for the application of several coatings to cylindrical hollow bodies by rolling the hollow bodies on an application device having a lacquer film wherein several hollow bodies roll on the lacquer film one after the other and wherein, for the application of at least the first coat of lacquer such hollow body rolls in the lacquer film which is progressively reduced by separation of lacquer on the application of lacquer to the preceding hollow body or bodies.

Abstract: An electrode for a biosensor (e.g., a glucose biosensor) has a layer of an electrically insulating polymer formed in situ on its operating surface by electropolymerization. For example, a diaminobenzene and a dihydroxybenzene (e.g., 1,3-diaminobenzene and resorcinol) are copolymerized on the electrode's surface by immersing the electrode in a circulating dilute solution of the monomers in deaerated phosphate buffer, and applying a small, continuously cycling voltage between that electrode and another electrode (e.g., from 0.00 V to 0.80 V) until current flow between the electrodes decreases to a minimum. Because the polymer is electrically insulating, polymerization ceases while the polymer layer is still very thin (e.g., 10 nm). An analyte sensing agent, e.g., an enzyme such as immobilized glucose oxidase, is imbedded in the polymer, but with a number of its analyte recognition sites unblocked.

Abstract: A porous glass optical fiber sensor, a method for its use, and a method for its manufacture. The sensor includes a glass optical fiber for conveying light, the fiber having a surface of interconnected and permeable chambers within the fiber, for optically sensing within the chambers. An indicator can be applied to the surface for sensing. The sensor is made by: first, drawing the fiber; second, heat treating the fiber to induce phase separation; and third, leaching a phase from the fiber. Thereafter, an indicator, such as a pH or moisture indicator, can be applied to the fiber for sensing. The sensor is used in conjunction with a light source, a light detector, and means for measuring change in the light caused by an agent within the porosity of the sensor.

Abstract: The overhead projector include a lower plate disposed on a housing of a main body of the overhead projector. The lower plate can rotate about a light axis of a condenser lens and has a transparent portion facing at least the condenser lens. A projection lens is supported above the condenser lens and an upper plate is disposed under the projection lens. The upper plate is supported vertically resiliently with respect to the projection lens and has a transparent portion at least facing the condenser lens. The upper plate is able to rotate about a light axis of the condenser lens. When images projected on a screen lie sideways or upside down, the upper and lower plates which are interposing a film therebetween are rotated. Thus, the directions of the projected images are correctly adjusted.

Abstract: An enclosed sanitizing cabinet for exposing eyewear articles to ultraviolet radiation from a fluorescent ultraviolet lamp which preferably extends substantially the entire height of the cabinet. The cabinet contains shelf-forming rod members spaced and configured to support eyewear articles in such manner that the surfaces of said articles which contact a user's skin in use are exposed to ultraviolet radiation. Interior surfaces of the cabinet are of a nature and formed of materials so as to reflect ultraviolet radiation to all articles therein and to minimize the differential in radiation exposure between articles adjacent and more remote from the radiation source.

Abstract: A method and apparatus is disclosed for measuring flowing gas and at least one variable for calculating gas flow corrected to a base value of that variable. Illustratively, the measured variables are temperature and pressure, and devices are employed for measuring the temperature T.sub.f and pressure P.sub.f of the gas flowing through a conduit, and means in the illustrative form of a flow meter for measuring the volume V.sub.f of the gas flowing through the conduit. Calculating means in the illustrative form of a programmed microprocessor is employed to calculate the corrected gas volume to base conditions in accordance with an expression including the supercompressibility factor. The supercompressibility factor is calculated according to an equation involving only whole number exponentiation and a selected set of coefficients. The calculation means selects a particular set of these coefficients in accordance with indications of pressure and/or temperature.

Abstract: A bi-directional, digital data transmission system is disclosed for transmitting an interrogation signal in a first direction from an interrogation unit to a data gathering transponder unit, and a data return signal in a second direction from the meter or data gathering transponder unit to the interrogation unit. This system comprises a single transformer having a primary winding coupled to the interrogation unit and a secondary winding coupled to the transponder unit. The interrogation unit generates an interrogation signal comprised of a first train of regularly occurring digital clock pulses and transmission interval pulses, each transmission interval pulse defining a transmission interval for the transmission of the data return signal. The transmission interval is set to be of a sufficient length to permit the transformer to desaturate to a level to permit efficient transmission of the data return signal to the interrogation unit.

Abstract: A utility data gathering system is disclosed as comprising a register including a series of index members coupled to a meter mechanism. Each index member includes a plurality of contacts and a switch arm moveable with its index member. The meter mechanism is responsive to utility consumption for moving the index members to positions indicative of the utility consumed, whereby each switch arm completes in normal operation a circuit with just one of its plurality of contacts dependent upon the position of its index member. A digital computer is programmed for performing first and second scans of each contact of each index member to obtain corresponding first and second sets of data indicative of a completed circuit through the switch arm and contacts of each index member. The completed circuit data obtained from each of the first and second scans are compared and if the circuit data of the first and second scans are different, an alarm manifestation is generated.

The circular slide rule comprises a basic disc, a centrally rotatable first rotary disc supported on one side of the basic disc but having a smaller diameter than the basic disc and a centrally rotatable second rotary disc supported on the side of the basic disc opposite to that of the first rotary disc but having a diameter smaller than that of the basic disc. Substantially straight cursors are also provided, each being rotatably supported on one of the rotary discs relative to the appropriate rotary disc and with respect to the basic disc, each said cursor extending at least to the circumference of the basic disc.

Abstract: A digital character generator method and system encode characters based on a normalized quad in accordance with coordinates of initial starting points of outlines of the character and variational parameters defining changes in those outlines such as slope and curvature. All characters of all formats are encoded for a maximum point size display. Vertical scaling factors permit character generation at any desired point size display. Horizontal scaling factors are employed both for transforming computations based on the encoded parameters for the normalized quad to a desired point size of display and also to adapt cyclic computations to the stroking density of a display CRT. .Iadd.
