Title: Hockey stick having an offset shaft and blade transitional connection
Inventor: UBRIACO GENE PAUL
IPC: A63B59/70
Filed: 1997-05-06
Abstract: A hockey stick is provided with an offset or bend angular to the plane of the face of the blade and positioned to begin substantially at the location where the transition from the heel of the stick to the shaft becomes approximately equal to the cross section of the shaft in its parallel plane. In a preferred form a second bend then makes a rapid transition to the full offset configuration within the dimension of the shaft such that the blade portion trails the plane of the center line axis of the shaft and due to centrifugal force the trailing blade tends to rotate closed thereby cupping the puck by the blade results in reduced deflection and easier pass reception. According to the preferred embodiments, the offset is positioned where it can be located closest to the blade and in the parallel offset form the completion of the offset to its full off-set dimension takes place dimensionally as is possible within a unitary stick construction of a blade with shaft receiving handle portion. The offset of the invention can be directed positively or negatively angled for different affects and performances.

Title: Method of producing reactive element modified-aluminide diffusion coatings
Inventor: AGUERO ALINA C
IPC: C23C14/16
Filed: 1995-11-09
Abstract: There is disclosed a process for forming aluminide diffusion coatings containing reactive elements on metal substrates such as iron, nickel or cobalt based alloys for protection against high temperature oxidation or corrosive environments. The process includes depositing a mixed metal coating containing aluminum and at least one reactive element onto the metal substrate and heat treating the coated substrate to induce interdiffusion of elements between the substrate and the deposited metal coating. In one aspect of the invention, the reactive element is yttrium and the metal coating is deposited by ion plating yttrium-aluminum by thermal evaporation from an yttrium-aluminum source. The coated substrate is heat treated between 500-1200 ~C to form a reactive element modified-aluminide diffusion coating having a thin outer Al2O3 coating formed thereon. An interdiffusion between components of the metal substrate and the deposited metal coating when the coated substrate is heat treated in an inert or reducing gas atmosphere.

Title: Service provision in a telecommunications network
Inventor: CRETCH PHILIP PAUL BARTLETT
IPC: H04Q3/00
Filed: 1996-03-22
Abstract: In a telecommunications network of the kind including service control points (6) which permit differing services to be provided to customers (5), centralised storage of data defining service provided to each customer is avoided. Whenever an update of service provided to a particular customer is required, such update is carried out centrally at a service creation point (10, 12). In the service creation point, data defining the current executable code deployed at the service control point (6) for that customer is recovered to enable recreation of the existing executable code to be carried out. The current code may then be modified regardless of which service creation point (10, 12) is carrying out the modification.

Title: Flavored flour containing allium oil capsules formed by protein coacervation and method of making flavored flour dough product
Inventor: GRAF ERNST
IPC: A23L13/40
Filed: 1996-04-04
Abstract: This invention is directed to an album flavored flour as well as to a method of making a flavored flour dough product. The allium flavored flour comprises flour and allium oil capsules formed by protein coacervation. The allium oil capsules are heat-stable and fracturable, and are added in an amount sufficient for flavoring when the flour is formed into a dough. Because the album oil capsules are heat-stable, the album oil does not affect the rheology of the dough during dough processing, baking or cooking. Furthermore, because the capsules are fracturable on chewing, the dough product provides a uniform and sustained allium flavor when eaten. In another aspect of the invention, the flavored flour or dough product further includes free allium material in an amount sufficient to reduce the mix time required to develop the dough. The free allium material may be combined with the oil capsules in a customized blend to provide the desired level of flavor and affect on dough rheology.

Abstract: A gyroplane (11) having a rotor blade (31) with an edgewise stiffness and blade weights of sufficient size to store a minimum of 100 foot pounds of rotational kinetic energy per pound of gross weight of the gyroplane (11) while the rotor blade (31) pitch is set to a minimum lift during blade prerotation. Then a clutch (105) driving the rotor (31) is disengaged and the rotor blade (31) pitch is changed to a lift condition. The horizontal velocity is increased to maintain altitude, first with the rotor blade (31) providing most of the lift and until the wings (19, 21) provide all the lift. During horizontal flight while the rotor blade (31) is loaded, the wing (19, 21) is maintained at a constant angle of attack and the horizontal stabilizer (43) is fixed and does not move. After the blade (31) is unloaded during horizontal flight, the rotor disc (31) and the horizontal stabilizer (43) are maintained generally at a zero angle of attack.

Title: Thermal down-mixing in diode laser transmitters to suppress stimulated brillouin scattering
Inventor: GOODWIN JOHN CHARLES
IPC: H04B10/18
Filed: 1996-12-06
Abstract: A method and apparatus for transmitting an analog signal over an optical fiber cable is disclosed. A semiconductor laser provides an optical carrier signal, the laser having the natural linewidth at high power of the same order as the SBS linewidth. The method comprises directly modulating the current of the laser with a dither signal comprising a first component fC and a second component fS. Due to the nonlinearity of the "I-V" characteristic of the laser, a thermal modulation component fT appears in the active region. This thermal modulation component reshapes the spectrum of the semiconductor laser to increase the threshold of the SBS. As a result, the energy of the signal transmitted over the optical cable may be increased by approximately 16 dB.  The first frequency is at least twice the maximum frequency of the analog signal and the second frequency is selected to obtain fC - fS = fT.

Title: Wdm optical signal transmission apparatus
Inventor: ITO TOSHIHARU
IPC: H04B10/2507
Filed: 1998-09-24
Abstract: It is an object of the invention to provide a WDM optical signal transmission apparatus, which improves transmission characteristics by allocating all the channels to the normal dispersion region of an optical transmission line without magnifying dispersion compensators.  The transmission line is composed of a main optical fiber, which covers the greater part of the optical transmission line, and two dispersion compensating optical fibers (the second dispersion compensators) located on both the ends of the main optical fiber. Since the transmission characteristic of the transmission line in the normal dispersion region is superior to that in the anomalous dispersion region, all the channels are allocated to the normal dispersion region of the main optical fiber.  The dispersion compensators located on both sending and receiving ends are composed of the first dispersion compensators for compensating accumulated dispersions of the respective channels and the second dispersion compensators for compensating negative dispersion of the center channel accumulated in the main optical fiber.  Since the second dispersion compensators can be used as the parts of the transmission line, the dispersion compensators located on both the sending and receiving ends can be small-size as compared with those in the conventional system.
