  • Patent number: 6198066
    Abstract: A method for treating the surface of a golf club part having a non-smooth surface such as a part which has been cast. Preferably, in those instances where the part is cast, the part is abraded for example by tumbling or by directing a light sandblast against the part to create a low reflectivity surface. Such abrading roughens the golf club part so that greater contrast can be obtained using radiated beam treatment. Surface roughening can also be created by acid etch or other suitable method. The club part is mounted in a beam treatment station to permit projecting a radiated beam on selected areas of the part's surface resulting in the momentary and superficial melting or fusing of the surface which makes such areas less rough and more light reflective than adjacent surface areas. Patterns are formed by causing relative movement between the part and a high energy heat source such as a radiated beam. Preferably the heat source or beam is held fixed and the part mounted on a movable table.

  • Patent number: 6198083
    Abstract: A process for heat treating steel wires in which the wires are passed through an induction furnace with induction coils connected in series to a common power supply. No more than one wire passes through any one of the induction coils. The wires are heated to their Curie temperature, where the wires become non-magnetic. This makes the process substantially self-regulating. If one or more wires are heated more rapidly than others, little if any heating of the more rapidly heated wires will occur after they reach their Curie temperature, and all wires will leave the inductive heating furnace at or near their Curie temperature. The system will operate satisfactorily with one or more wires missing. When this happens, for loading purposes or other reasons, the efficiency of the unit degrades but sufficient excess power remains such that heating of the wires that are passing through the system will be relatively unaffected at the design mass flow rate.

  • Patent number: 6198088
    Abstract: A platen cover assembly of an image processor includes a light source array that has a plurality of light sources arranged in a two-dimensional light source array, and a translucent white material covering at least a side of the light source array that faces a platen of the image processor. When a document is placed on a platen and covered by the platen cover assembly, a first scan of the platen is performed with a document illuminator of the digital image processor deactivated to sense light from exposed light sources of the light source array. The document illuminator is then activated, and a second scan is performed to obtain image data from the document. The obtained image data is then processed based on the size, location and/or orientation of the document, as determined from positions of the light sources detected during the first scan.

  • Patent number: 6198089
    Abstract: A circuit architecture for computing the outputs of odd and even symmetric spatial filters simultaneously comprises at least two resistive networks interconnected by at least one controlled current source. In one embodiment the nodes of the resistive network are arranged in a two-dimensional array to allow filtering of two-dimensional signals such as images. The resulting filters are orientation selective. The spatial orientation and the scale of the filter can be selected by appropriately tuning the resistive elements forming the resistive networks and the gains of the controlled sources. The controlled sources may be voltage controlled (eg transconductance amplifiers) or current controlled. This circuit architecture may be implemented in VLSI to incorporate both image sensing and orientation selective filtering on the same chip.

  • Patent number: 6198090
    Abstract: A night vision device (10) with an image intensifier tube (14) includes an improved microchannel plate (22) which has an extraordinarily low indigenous population of gas molecules. Because of this low population of gas molecules, positive ions produced from these gas molecules in the high voltage operating environment of the image intensifier tube (14) are of such a low number that the image intensifier tube (14) will operate for a satisfactory service life even though the microchannel plate (22) has no ion barrier film. The microchannel plate (22) is also spaced much closer to a photocathode (20) of the image intensifier tube (14) than has heretofore been possible. Thus, improved gain and reduction or elimination of image halo also results from the present invention.

  • Patent number: 6198096
    Abstract: A technique for analyzing ions by determining the time of flight of the ions from a source before detection at a detector. In the technique a series of pulses is generated according to an encoded sequence. Pulses from the series of pulses are selected to launch a plurality of packets of ions from the source, each of the selected pulses launching a packet of ions such that ions launched in the adjacent packets overlap prior to reaching the detector. At the end of the series another cycle of the series is generated again and some of the pulses in the series are selected in the another cycle to launch a plurality of packets of ions from the source. The cycles of pulse generation and selection to launch ions are repeated. The time of arrival of the ions of each packet in the detector is determined to obtain signals corresponding to overlapping spectra of the time of arrival of the packets of ions.
