IPC: F24H7/00
Filed: 1991-05-13
Granted: 2002-04-23
Abstract: A storage generator for a convention oven through the oven chamber of which heated air is moved by means of a fan along a flow path in which the steam generator is positioned, comprises a heat-storage unit having a plurality of elongate horizontal supports for supporting ball-shaped heat-storage bodies and means for spreading water over the heat-storage unit. Each support includes a bottom wall having a plurality of polygonal apertures which form seats for respective ones of the heat-storage bodies.

Title: Method of reprocessing cured polysulfide and/or polymercaptan elastomers
Inventor: UNGER GERFRIED
IPC: C08J11/28
Filed: 1992-12-01
Granted: 2003-02-04
Abstract: This invention relates to a method of reprocessing cured polysulfide and/or polymer-captan elastomers. For the reprocessing, 0.5 to 400 percent by weight cured polysulfide and/or poly-mercaptan elastomers are reacted with liquid di- or polymercapto compounds to form liquid-to-pasty mercapto-terminated prepolymers. The cured polysul-fide and/or polymercaptan elastomers are chemically substantially inert and can be rendered useful in that manner and can be used again as polysulfide and/or polymercaptan sealants.

Abstract: A process for making a thermoformable conductive plastic laminate for use in making plastic parts adapted for electrostat-ic spray painting of a uniform high quality paint finish includes forming a matte release coated casting sheet (20), casting an elec-trically conductive polymer (24) in thin film form on the casting sheet, drying to form a conductive primer coat (24), and transfer-laminating the conductive coating to a thin, thermoformable plastic face sheet (26). The matte release coat (20) has fine particu-late filler that transfer a micro-roughened matte surface to the conductive primer coat (24). The conductive primer (24) includes a polyester resin containing a fine particulate conductive material such as carbon black and, preferably, an anti-blocking agent such as fumed silica. The primer coated face sheet (26) can be thermoformed and bonded to an underlying plastic substrate panel (28). The conductive primer (24) has sufficient elongation and maintains uniform electrical surface conductivity and film thick-ness throughout the transfer-laminating, thermoforming and substrate panel-cladding process. The uniform surface resistivity of the conductive primer film (24) is sufficient to permit electrostatic spray painting of the finished contoured panel and in one em-bodiment of the finished contoured panel and in one embodiment produces a Class "A" quality, exterior-automatic paint finish on the resulting panel.

Abstract: An improved plastic, clamp-style garment hanger is provided.   The hanger provides two clamps disposed on an I-beam-like crossbar on opposing sides of a hook.  The lateral positions of the clamp are adjustable.  The spring-clip that biases the garment engaging surfaces of the clamps together also provides frictional engagement between the clamps and the upper ridge of the crossbar.  Hooks disposed at either end of the crossbar are suitable for engaging straps and also limit the outward lateral position of the clamps.  Steps or stacking ribs disposed adjacent to the hook limit the inward lateral movement of the clamps.  The spring bias of the spring-clip against the clamps resists clamp creep under the weight of a heavy garment.

Abstract: A Raster Output Scanner (ROS) assembly is mounted within a printing machine frame so as to maintain a very precise relationship with the photoreceptor being imaged. A ROS housing is mounted in relation to the photoreceptor so that, while the housing is fixed to a machine frame by isolators to damp out vibrations and transients, a mechanical latching to a photoreceptor backer bar provides a degree of rotational movement consistent with movement of the photoreceptor. Thus, errors created by photoreceptor motion are compensated for. The invention discloses a 3 or a 4 point mounting arrangement which affords a high degree of stability coupled with conformance with exacting registration tolerances.

Title: Method and apparatus for accurate frequency synthesis using global positioning system timing information
Inventor: HATCH RONALD R
IPC: G01S1/00
Filed: 1996-09-03
Granted: 2000-12-12
Abstract: A method and apparatus for synthesizing a stable reference signal of a desired frequency within a spread spectrum receiver is disclosed herein. The spread spectrum receiver is designed for use in conjunction with a global positioning system (GPS) receiver, and operates to receive broadcast differential GPS correction information. The present frequency synthesis technique contemplates generating a sequence of timing signals within the GPS receiver on the basis of GPS satellite signals received thereby, and providing the timing signals to the signal receiver. Within the signal receiver,the signal cycles of a local oscillator occurring between ones of the timing signals are counted. The frequency of the local oscillator is then determined by dividing the counted cycles of the local oscillator by one of the known time intervals. The determined frequency of output signals produced by the local oscillator is then scaled so as necessary to produce the reference signal of desired frequency. This allows precisely controlled reference frequencies to be obtained irrespective of the existence of frequency instability within the local oscillator. In a preferred implementation, the stable reference signals are employed during acquisition of differential GPS correction signals received by the spread spectrum receiver. In particular, the desired reference frequency is incrementally adjusted during the process of searching for and acquiring the exact frequency of the incident differential GPS correction signals. The spread spectrum receiver is disposed to provide differential GPS correction information extracted from the acquired differentialGPS correction signals to the GPS receiver.

Abstract: In three-dimensional seismic surveys using the Vibroseis system, cost savings can be made if multiple sources are used simultaneously, into the same set of geophones. Each source radiates a distinctive source signal, so that reflections generated by each one may be separated from those generated by the others. These signals should have little or no correlation with each other, and each should be substantially immune from harmonic distortion present in any of the others. The invention employs long but identical swept-frequency signals, for which the time to sweep through one octave exceeds twice the maximum seismic travel time of interest. For one swept-frequency signal a frequency-time space is defined between the signal itself and a nominated harmonic (for example, the second), and the other swept-frequency signals are accommodated within partitions of this frequency-time space. The invention is particularly appropriate to inexpensive swinging-weight vibrators.

Title: Currency discriminator having a jam detection and clearing mechanism and method of clearing a jam
Inventor: MENNIE DOUGLAS U
IPC: G06Q20/00
Filed: 1995-09-07
Granted: 2000-12-12
Abstract: A currency counting and discrimination machine for rapidly counting and discriminating currency bills is set forth having a jam detection and clearing mechanism. The machine has a transport mechanism which engages and transports the currency bills, one at a time, along a transport path from an input receptacle to an output receptacle. A sensing device for scanning and counting the currency bills is adjacent a segment of the transport path. Several sensors along the transport path detect when a currency bill becomes jammed. Once a jammed currency bill is detected, the operation of the transport mechanism is interrupted. A portion of the transport mechanism is then adjusted to relieve pressure exerted on the jammed currency bill by the transport mechanism. The transport mechanism is then reactivated to remove the jammed currency bill from the transport path.
