Granted: 2006-07-05
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 DEG  to about 120 DEG  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 side wall (34). The debris channel side wall (34) is on an angle from about 10 DEG  to about 20 DEG  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). <IMAGE>

Abstract: Disclosed is a single mode optical waveguide fiber having a segmented core. The relative indexes, the refractive index profiles and the radii of the segments are chosen to provide waveguide fiber properties advantageously used in severe environments, such as, undersea cables. The segmented core waveguide fiber has a negative total dispersion over the operating window, which serves to eliminate soliton formation. The key properties of dispersion zero, total dispersion cut off wavelength, attenuation, and effective area fall within desired ranges. The waveguide also features a low polarization mode dispersion. <IMAGE>

Abstract: A method of making an electrically insulated terminal (12) in an injection nozzle (10). After the heating element (44) is wound in a spiral channel on the outer surface (36) of the main body portion (14) of the nozzle the rear end (104) projects radially out an opening (80) in the collar portion (16). The casing (102) is stripped from the heating element to expose the resistance wire (112) adjacent the rear end. A steel plug (78) having a central bore (76) therethrough is slipped over the projecting rear end and welded into place in the opening. A steel terminal body (82) is made with a central bore (106) and a threaded front portion (84) to receive an external power lead (118). The casing (102) of the portion of the heating element (104) projecting from the plug and a rear portion (88) of the terminal body (82) are coated with insulating material (92). A protective cap (94) is securely swaged over the coating on the rear portion. The assembled cap and body are slipped over the rear end of the heating element and welded to the matching front face (100) of the plug (78). The exposed resistance wire (112) is welded to the terminal body (82). This structurally secures the terminal body against torque from connecting and disconnecting the external lead and electrically insulates it from the rest of the nozzle, while electrically connecting it to the resistance wire. In an alternate embodiment, the connections are made while integrally brazing the nozzle in a vacuum furnace.

Abstract: An adder cell for a ripple-carry adder, suitable for use in an integrated circuit employing CMOS technology, has a gate arrangement for two input variables and a carry input signal, with outputs for sum and carry signals, in accordance with the signals presented to the inputs. The gate arrangement is arranged so that the charging of the capacitance of the carry output takes place from a supply voltage through two transistor gates, not contained in a combination gate, so that one of the transistor gates may be formed as a driving inverter separate from the time-critical carry-propogation path, and designed with significantly lower impedance than the other transistor gates. Alternatively, a single transistor gate is employed for charging the capacitance of the carry output directly form a supply voltage.

IPC: H01M4/88
Filed: 1988-10-31
Abstract: This disclosure is directed to a non-bleeding gas electrode for operation under the rigors of high current density and to the active layer thereof. This active layer is comprised of 60 to 90 weight percent high surface area, electroconductive carbon (with or without catalyst thereon), 10 to 40 weight percent particulate polytetrafluoroethylene (PTFE) and has pores sufficiently large to relieve internal hydrodynamic pressures thus preventing liquid being forced through the electrode wetproofing layer to the air side thereof. In addition such electrodes include a PTFE-containing wetproofing or backing layer secured on one side to said active layer and on the other side to a current distributor. The pores in both the active layer and the backing layer are controlled to relieve hydrodynamic pressures by coordinating the particle size of the pore former used to establish the pores in both said layers such that the repellancy of the backing layer to hot alkali exceeds the internal liquid pressures in the active layer. Of particular significance is the fact that the present electrode is non-bleeding when operated on air and preserves its low voltage at high current density over extended time periods without bleeding.

Granted: 1999-08-30
Abstract: This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation. One such compound is triphenylcarbenium tetrakis(pentafluorophenyl)boronate. The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity. This new synthesis is a clean reaction which does not produce a Lewis base. The process generates active catalysts by removing a methyl anion from a group IV metallocene derivative.

Abstract: An SCR catalyst containing titanium, molybdenum and vanadium has the particular characteristic that its catalytic activity is significantly less than that of a tungsten-containing catalyst. That disadvantage has been compensated for in the past by using a comparatively large volume of catalyst. In contrast to the conventional practice of using a molybdenum oxide proportion of about 10 to 12% by weight, the invention proposes that the molybdenum proportion of the catalyst, in the form of molybdenum trioxide MoO3, is about 0.01 to 5% by weight, preferably 1.5 to 4% by weight, relative to the weight of the catalyst mass. A catalyst containing this amount of molybdenum thus has an activity comparable to that of a tungsten-containing catalyst. The invention is applicable to all deNOx catalytic converters which call for the simultaneous presence of a reducing agent, in particular plate-type and honeycomb-type catalytic converters.

The filler includes a flexible laminated structure having a plurality of layers (31, 32, 33; 32a, 32b; 34) which are mounted to be moveable relative to one another under the effect of a non-uniform distribution of force compressing the filler in the absence of a controlled pressure. The cover (29) is coupled to a vacuum source and is adapted to receive a controlled pressure to make the supporting element more or less rigid. When the cover (29) has a predetermined inner pressure, the relative displacement of the respective layers is prevented thereby giving the layers a predetermined rigidity. The layers may have a device for immobilizing the layers distributed on either side of at least one compressible layers (32, 32a, 32b).
