Granted: 1983-03-29
Abstract: 48,105 ABSTRACT OF THE DISCLOSURE           An efficient fluorescent lamp of high brightness and compact size is provided by forming the envelope from vitreous tubing that is bent into three U-shaped sections which are disposed in mutually perpendicular planes and define  a  single  convoluted  discharge  channel.   The U-shaped sections are so oriented that the legs of the U's are disposed in quadrangular columnar array with the ends of the tubing located adjacent one another and opposite one of the U-bends.   Conventional  electrode-stem assem-blies are sealed into the ends of the bent tubing and the sealed legs are coupled to each other and the proximate U-bend by brace means which rigidifies the multi-section envelope.  An efficient method of manufacturing the enve-lope employing a pair of arcuate molding components and two bending operations that form the three U-bends with only a single tube-heating operation is also disclosed.

Title: Method and apparatus for producing a speed pattern  for an elevator car or similar vehicle
Inventor: GINGRICH JOHN A
IPC: B66B1/30

Granted: 1982-01-05
Abstract: ABSTRACT         A system for producing a velocity pattern for a vehicle such as an elevator car which must be brought smoothly to a stop accurately aligned with a desired one of a number of stations.          The distance between the vehicle and the station at which a stop is required (target distance) is expressed in digital form, and is processed electronically to produce a velocity pattern which results in constant deceleration of the vehicle during the entire approach except for an initial build-up to, and a final tapering off from, the constant deceleration.  A single adjustment for deceleration rate automatically adjusts the slowdown distance to the correct value to suit the selected deceleration rate.          The calculation is done repetitively at high speed to minimize any lag between the diminishing target distance and the corresponding velocity pattern.  Further adjustments permit control of the final tapering off from constant deceleration, with the slowdown distance automatically adjusted to suite these adjustments also.

Abstract: ABSTRACT OF THE DISCLOSURE        Compositions capable of evaluating the activity of dental caries using color reaction, which comprise an aqueous solution containing coloring agents and water-soluble subs-tances capable of producing an osmotic pressure higher than physiological pressure on the cell membrane of cariogenic bacteria but are free from any buffer action by themselves.          Upon introducing dental plaque of a dental caries of a patient into this solution and measuring the activity of the sordes by means of color reaction, it is possible to readily evaluate the actual state of dental caries and its activity without any cul-tivation of cariogenic bacterial being required.

Title: Construction of thread treating nozzles
Inventor: NABULON WERNER
IPC: D02J1/00
Filed: 1981-03-30
Granted: 1984-01-24
Abstract: Abstract A texturising nozzle for synthetic filaments is openable and closable to facilitate lacing up. The nozzle comprises a two-part carrier structure with the parts movable towards and away from each other to open and close the nozzle. The thread path through the nozzle is defined by means of insert elements releasably mounted on the carrier structure at least in that region of the path in which the main texturis-ing step is performed. A thread infeed passage and a (pre-ferably single) fluid infeed passage bring thread and treat-ment fluid together at a junction location, and a guide passage (which preferably widens in the downstream direction) leads the thread and fluid from the junction location to the texturising region.

Abstract: ABSTRACT OF THE DISCLOSURE            For fluorescent lamps which use a double layer of phosphor with manganese-activated zinc silicate phos-phor in the overlying layer, a small predetermined amount of finely-divided antimony oxide is added to the first phosphor layer coating paint which, after application, is lehred at a temperature which is sufficient to volatilize the organic binder but which is insufficient to volatilize more  than  a  minor  proportion  of  the  antimony  oxide. Thereafter, the second phosphor layer coating paint which includes the  zinc  silicate  is  applied over the first-applied layer and the applied second layer coating paint is then lehred at a temperature which is sufficient to volatilize an appreciable portion of the residual antimony oxide in the first-applied layer to cause the volatilized antimony oxide to contact the zinc silicate.

Abstract: ABSTRACT OF THE DISCLOSURE:           For the detection of accumulations of particles, for instance metaphase plates, in an image converted by a raster process into electrical signals, there is first effected an electronic dilation in several directions, the parameters of the dilation being so selected that images of the chromosomes of the metaphase plates agglomerate to form unitary structures.          Thereupon, an electronic erosion of images is effected in several directions, the parameters of the erosion being so selected that images of cells and impurities disappear but the agglomerated metaphase-plate images are retained.  A circuit is described which consists essentially of length discriminators, decision-logic devices, delay-storage devices with provision for establishing input digital preset values, in which circuit the entire evaluation process takes place with the speed of the scanning process.

Abstract: VIDEO TAPE RECORDER                    ABSTRACT OF THE DISCLOSURE         In an apparatus for recording and/or reproducing a television signal with multiplex audio signals, a pilot signal is recorded on one or both of the audio tracks of a video tape in a manner to identify the mode of the mutli-plex audio signals and each pilot signal is detected to establish such mode when reproducing.  For example, the frequency of the pilot signal may be changed for identifying different modes of the multiplex audio signals, such as, the bilingual mode and the stereo-phonic mode, with the pilot signal of selected frequency being recorded on one of the audio tracks or the pilot signal having a certain frequency is recorded on one of the audio tracks in the case of the bilingual mode, and on the other audio track of the tape in case of the stereo-phonic mode.  In still another embodiment, the pilot signal is recorded in both audio tracks of the tape and the phase relation of the recorded pilot signals is varied to identify the mode of the multiplex audio signals.

Granted: 1984-10-09
Abstract: FOLDING SCREEN FOR LIGHT-PERMEABLE SKYLIGHTS AND THE LIKE                  ABSTRACT OF THE DISCLOSURE A folding screen is formed by a plurality of successively hinged, rigid, radiation-controlling planar panels supported so the screen can be opened (or extended) and closed (or collqpsed). Adjacent panels are supported only at their edges, by a hinge member having symmetrical back-to-back tubular channels. The hinge member possesses sufficient rigidity to permit hinged, side-by-side coaction of the panels from a stacked, generally vertical relationship when the screen is collapsed, to an undulating planar relationship when the screen is opened, which relationship is essential if the screen is to be collapsed without binding. The screen is translatable on a pair of parallel, mono-level tracks, and operated by a flexible drive member extending along a rail and connected to the screen's leading ("lead") panel. A novel skylight includes a curb assembly, a "bubble" (or "dome") and a folding screen translatable to-and-fro below the bubble. The curb assembly is mounted on a curb provided on the roof, and the assembly includes an access panel which allows access to the folding screen housed in the assembly. The access panel is adjacent the skylight's bubble which is mounted on the walls of the curb assembly. This construction of the curb assembly permits maintenance of the folding screen without disturbing the seal of the bubble on the walls.
