Abstract: A color picture tube has a rectangular shadow mask mounted therein in spaced relation to a viewing screen. A major axis passes through the center of the mask and parallels the long sides thereof, and a minor axis passes through the center of the mask and parallels the short sides thereof. The mask has an aperture array that includes slit-shaped apertures aligned in columns that essentially parallel the minor axis and end at a border of the aperture array. Adjacent apertures in each column are separated by tie bars in the mask that are longitudinally offset from column to adjacent column. The spacing from tie bar to tie bar in a column is the tie bar pitch at a location on the mask. A first set of the aperture columns, comprising every other column, has full length ultimate apertures at least at one end thereof, and a second set of the aperture columns, comprising every other column not in the first set, has partial length ultimate apertures at least at one end thereof. The ultimate apertures of all of the aperture columns end on smooth curved border lines. The tie bar pitch of the columns decreases from the center of the mask to the short sides thereof, and the tie bar pitch along each column varies from the center of the mask to the long sides of the mask.

Title: Multi-roller electrostatic toning system application to tri-level imaging process
Inventor: CHRISTY ORRIN D
IPC: G03G15/08
Filed: 1996-05-08
Abstract: Images are formed using first and second fluidized beds of non-magnetic toner having first and second, respective, single applicator rollers. A charge retentive surface such as a photoconductive belt is uniformly charged (e.g. by a corona device) to a predetermined voltage level, and at least first and second different, spaced, latent electrostatic images are formed on the surface at different locations (such as by a laser based output scanning device). The surface is then moved past the first applicator roller, and then the second applicator roller. The first fluidized bed and applicator roller are electrically biased at a first bias level effective so that the first image is developed by a non-magnetic toner transferred from the first applicator roller to the first image while development of the second image is precluded, and the second fluidized bed and second applicator roller are electrically biased at a second bias level effective so that the second image is developed by non-magnetic toner transferred from the second applicator roller to the second image while development of the first image is precluded. A negative bias may be applied to the first fluidized bed and a positive bias to the second fluidized bed, while the first and second rollers are positively biased at voltage levels at least 50 volts different. Black toner may be applied by the first fluidized bed, and colored toner by the second bed. A transfer roller may be used to transfer toner from each of the fluidized beds to its associated applicator roller.

Title: Foraging unit for avian, mammalian and reptilian species and method of use
Inventor: NURMIKKO MIKA
IPC: A01K5/01
Filed: 1997-03-27
Abstract: A stimulative feeding device for use by animals. The device is designed as a function of the specific animal for which it is intended, with the underlying characteristic that the animal is required to use its natural foraging capabilities to recover food from the device. The device includes a basic structure having a plurality of cavities for retaining a supply of food for the animal. The basic structure is opaque so that the animal cannot see through it to observe some or all of the food. A portion or all of the cavities are hidden so that the animal is required to manipulate any hiding component in order to expose the food. The means for hiding the food can be as varied as the skill level of the animal for which it is intended. The device is not designed to teach the animal, but is instead designed to occupy that animal's time through activities that it would ordinarily carry out while in its natural environment. Although the device may be configured to suit most any animal, particularly those in captivity, attention is directed to avian, mammalian, and reptilian species.

Abstract: A very high speed adiabatic face milling machine whose configuration and operation provide a highly efficient machining process suitable for production manufacturing conditions.  The milling machine preferably operates at speeds of approximately 15,000 sfm and at efficiencies of approximately 7 cubic inches per minute per horsepower.  The preferred milling operation is conducted without the use of cooling liquids, instead employing a chip removal system which enables the milling machine to operate truly adiabatically such that no heat is transferred to the workpiece or the cutter.  The efficiency of the chip removal system is such that chip recutting is nearly eliminated and tool life is improved.  The milling machine also includes an improved cutter structure, fixturing, and transfer devices.

IPC: H04L69/14
Filed: 1997-09-15
Abstract: A universal phone located in a foreign country provides home country telephone appearance and functions for a caller visiting the foreign country. The universal phone includes a database of national telephone features that are characteristic of the caller's home country. The universal phone includes a smart card adapter that receives a smart card presented by the caller, bearing information of the caller's ID, the caller's home country, and other information. When the caller inserts his smart cart into the universal phone, the caller's home country information is read from the card. The home country information is used to access the database to obtain the telephone appearance and functions of the home country. The text of messages in the language of the home country is displayed on a display screen of the universal phone. The image of the dialing key pad is also displayed on the display screen. The action to be performed in response to each key is provided to logic associated with a touch overlay membrane positioned on the surface of the display screen. When the caller presses the touch overlay membrane at a location over the image of a key,the corresponding action is performed by the logic. Actions include forming a string of dialing digits in the home country's format, for transmission to the universal server. The universal server translates the caller's dialed number in the caller's home country format, into a network code that enables establishmentof the call.

Title: Network based multimedia messaging method for non-ccitt compliant switches
Inventor: BRUNO RICHARD F
IPC: H04M7/00
Filed: 1997-03-12
Abstract: A method is disclosed for messaging multimedia calls with a non-CCITT  compliant switch when the intended recipient is unavailable. The method is used in connection with a telecommunication network which has an identified multimedia server (92). According to the method, multimedia calls from a caller, using a multimedia device (70) running a first application and a second application, are messaged when the called party is unavailable. The method involves initiating a multimedia call to the called party using the first application and determining that the multimedia call is an unanswered call using the second application. Using the second application, the first application is signalled to indicate that the multimedia call was unanswered.  In response to the signal, an X.25 packet message is sent from the multimedia device to the identified network based multimedia server. The multimedia device receives back a messaging address identifying a multimedia messaging server (100) from the network based multimedia server. A second multimedia call is initiated from the multimedia device (70) to the identified multimedia messaging server (100) using the first application and the messaging address.  The method then involves connecting to the multimedia messaging server indicated by the messaging address and recording a multimedia message on the network based multimedia messaging server.
