Abstract: A cutting tool or drill bit (10) has a shank (12) with two ends. A chucking end (14) is on one end of the shank (12) and a cutting end (16) is on the other end of the shank (12). At least one flute (30) is formed on the shank (12) between the chucking (14) and cutting ends (16). The flute (30) includes a web (36) and a debris channel (32). The web (36) includes a first (38) and second (40) surface continuous with a debris channel side wall (34). The first surface (38) is substantially parallel to the shank longitudinal axis (18) and the second surface (40) is on an angle from about 100° to about 120° with respect to the shank longitudinal axis (18). The second surface forms the base of the debris channel or groove (32) with the debris channel aide wall (34). The debris channel side wall (34) is on an angle from about 10° to about 20° with respect to the shank longitudinal axis (18). A ratio exists between the axial length of the first surface to the axial length of debris channel surface of about 2:1 to about 4:1. Also disclosed is a method of cold rolling a blank (60) to form the above drill bit (10).

Title: Method and apparatus for reducing false rejection in a speech recognition system
Inventor: GUPTA VISHWA NATH
IPC: G10L15/01
Filed: 1996-11-27
Granted: 2002-07-16
Abstract: The invention relates to a method and apparatus for grouping orthographies in a speech recognition dictionary to reduce false rejection.   In a typical speech recognition system,  the  process  of  speech  recognition  consists  of scanning  the  vocabulary  database  by  using  a  fastmatch algorithm to find the top N orthography groups. In a second pass the orthographies in the selected groups are re-scored using more precise likelihoods. The top orthographies in the top two groups are then processed by a rejection algorithm to find if they are sufficiently distinct from one another. In the affirmative the top choice candidate is accepted, otherwise the entire procedure is terminated.   The novel method  comprises   the   steps   of  grouping  confusable orthographies together to reduce the possibility of false rejection.

Abstract: A portable trench barrier is capable of greatly reducing the number of beetles migrating into a cultivated area, such as a field of potato plants.  The device comprises a series of linear barrier sections and connector pieces joined together to enclose and protect a cultivated area.  Each linear barrier section comprises an extruded plastic section having (a) an elongated floor section, (b) a pair of continuous leg portions extending downwardly from the side edges of the floor portion. The leg portions are adapted to penetrate the soil and form a continuous sub-surface barrier.  A pair of opposed upwardly inclined elongated ramp portions extending upwardly and inwardly from the side edges of the floor portion, these ramp portions terminating in downwardly curved free edge portions having smooth outer surfaces with the curved free edge portions of the opposed ramp portions forming therebetween a gap having a width of up to about 20 mm.  The opposed ramp portions and gap are arranged such that beetles are able to climb the ramp and continue along the ramp until they reach a point on the curved free edge portion where they lose their footing and slide down into and are trapped in a chamber formed by the floor section and ramp portions.

Abstract: A veneer drying apparatus comprises a pair of upper and lower hot plates connected to a heating unit and a plurality of steam escape grooves formed in the opposing press surfaces of the upper and lower hot plates. The apparatus further comprises intermittently driven endless belts and driving and driven rollers on the unloading and loading ends, respectively, of the lower hot plate. The endless belts are trained over the driving and driven rollers for transferring veneer P over the upper surface of the lower hot plate. Each endless belt has numerous apertures formed in the entire surface thereof in a regular pattern. The driving rollers have numerous protrusions formed on the periphery thereof for engaging in the apertures formed in the endless belts. The endless belts are smoothly driven by rotation of the driving rollers due to the protrusion-aperture engagement.      Not driven by friction, the endless belts can be relatively thin, so that the entire apparatus can be simplified and made smaller while achieving improved transfer of heat from the belt to veneer P and permitting easy belt replacement.

Inventor: SIEPMANN FRIEDRICH W
IPC: C12Q1/02
Filed: 1996-09-18
Granted: 2011-11-01
Abstract: In order to determine the biological oxygen demand of sewage, a sample of sewage is taken into a reaction vessel (1) in which there is a biological bath (2) which is kept moving turbulently by an agitator (6). An oxygen probe (8) measures the oxygen consumption per unit time. The biological oxygen demand is determined from the dilution ratio between the sewage sample taken and the dilution water in the reaction vessel (1) and from the oxygen consumption per unit time. After each measuring cycle the reaction vessel (1) is rinsed with diluting water and is then ready for another measuring cycle. The reaction vessel (1) penetrates into the sewage to be tested.

Abstract: An apparatus and method is provided for placing a phone call when dialing out of the caller's local area. A database resident in a telephone connection mechanism contains the access codes required to place the out-of-local area call.  A user input device is utilized by the calling party to retrieve the out-of-area access codes for the called party's telephone from the database.  The user input device is also utilized by the calling party to input the called party's local telephone number into the  telephone  connection  mechanism.    The  telephone connection mechanism automatically combines  the  local calling number input by the user with the out-of-area access codes retrieved from the database.  The telephone connection   mechanism   then   transmits   a   telephone connection  request  by utilizing  the  combined  local telephone number and the out-of-area access codes.   The present invention also verifies out-of-area access codes that are directly input by the calling party to ensure their accuracy and corrects any incorrect access codes input by the caller.

Filed: 1999-07-23
Granted: 2003-04-01
Abstract: A method and system provide enhanced caller identification information to a called party. The system determines whether or not standard caller identification information associated with a calling party can be provided to the called party. The system preferably determines whether the standard caller identification information is unavailable, incomplete or has been blocked. When the system determines that the standard caller identification information cannot be provided, the system transmits a request for audible caller identification information to the calling party. If the calling party provides the requested audible caller identification information, the audible caller identification information is transmitted to the called party. The called party is thus provided with information about the calling party that can assist the called party in deciding whether or not to answer the call.
