Title: Roller cone bits with wear and fracture resistant surface
Inventor: CAWTHORNE CHRIS
IPC: B22F1/12
Filed: 2002-05-01
Abstract: Rock bits comprising wear and fracture resistant surface of this invention include a steel bit body having at least one leg extending therefrom. A steel cone is rotatably disposed on the leg. The steel cone includes a plurality of steel cutting elements that each projecting outwardly a distance therefrom.      At least a portion of the cone comprises a wear resistant surface formed from a wear resistant composite material. The wear resistant composite material is made by the process of combining powders selected from the group consisting of carbides, borides, nitrides, carbonitrides, refractory metals, cermets, Co, Fe, Ni, steel, and combinations thereof, to form a material mixture. The material mixture is applied onto a designated surface of the cone, in one form or another, when the cone is in a pre-existing rigid state. Depending on the particular application, the material mixture can be applied in as a slurry to the designated surface of the cone to form a coating thereon. Alternatively, the material mixture can be preformed into a green part that is configured to be placed over the designated surface prior to being disposed thereon. The material mixture is then pressurized under conditions of elevated temperature to form the wear resistant surface. In the event that the material mixture is preformed into a green part, the preformed green part can be sintered prior to its placement on the designated cone surface.      The sintered part can then be attached to the cone surface by brazing process.

Abstract: The invention relates to the production of gelatins from the skins of marine  animals and residues of connective tissues from fasciae and muscles by means  of several production stages. After washing the skins and/or connective tiss ue several times by strongly shaking them in a cold sodium chloride solution, they are treated with a diluted alkali and then neutralized and washed with water. Treatment with organic acid is of fundamental importance. The use of acetic or lactic acid may be of interest to obtain high rheological properti es and yields. After washing, the gelatin is extracted in water by means of hea t treatment. Subsequent drying is performed by means of heat, spraying or lyophilization. Several compounds are added to this proteic material to form  the final product or gelatin.

Title: Method for separating a machining suspension into fractions
Inventor: MALBERG ANDREAS
IPC: B01D21/01
Filed: 2000-10-31
Abstract: The invention relates to a method for separating a machining suspension, which accumulates for example during the mechanical machining of silicon, quartz or ceramic, from a cutting fluid. Abrasive grains, in addition to attrition material from both the machined material and the machining equipment are dispersed in said cutting fluid. According to said method, the suspension is separated by wet-sizing, whereby the liquid used for said wet-sizing process is selected so that it can be mixed with the cutting fluid used and that the resultant mixture forms a stable suspension, in particular with the attrition material from the machined material. The method enables the abrasive grains to be separated cleanly from the attrition material and the cutting fluid.

Abstract: A wafer level packaging method which produces a stacked dual/multiple die integrated circuit package (91). In the method, the wafer with the smaller sized dice (15) of two wafers is processed through a metal redistribution process and then solder balls are attached. The wafer is then sawed into individual die size ball-grid array packages. On the wafer with the larger sized dice (25), a die attached adhesive material (18) is deposited on the front of each die site location that is intended for the attachment of one o f the die-sized BGA packages. The back side of the BGA die package is placed onto the adhesive material and is cured. A wirebonding operation connects th e signals from the die-size BGA package to the circuits of the bottom die. A coating material (80), such as epoxy, is disposed on the wafer to cover the wirebond leads and the assembly is then cured. Then, the stacked-die wafer i s singulated into individual stacked-die IC packages (91).

Title: Method and apparatus for enabling random access to individual pictures in an encrypted video stream
Inventor: SO NICOL CHUNG PANG
IPC: H04N7/167
Filed: 2000-05-02
Abstract: A system for providing conditional access to packetized picture (video), aud io or other data. The system selectively encrypts packetized data (105) such th at transport packets (130, 150) that include header data (131, 151) are unencrypted, while all other transport packets (140, 141) that do not includ e header data are encrypted. This allows the transport packets with the header  data (130, 150) to be randomly accessed from a memory (230, 310), which is particularly advantageous for performing "trick modes", such as fast forward  and fast reverse, e.g., in a video-on-demand service. After the transport packets are selectively encrypted and stored, transport scrambling and contr ol bits (132, 142, 152) for each packet (130, 140, 150) can be accessed to determine whether the packet is encrypted, and consequently, whether the packet includes header data. If a packet includes header data, it is suitabl e for use in a trick mode since it provides data from the start of a video, audio or other data packet.

Abstract: -12- A shopping cart with dedicated multi- compartments is described. There are five distinct compartments which are shallow and formed of wire mesh to provide visibility of the articles in the compartments whereby a person can quickly examine the articles placed in each of the compartments to ascertain their nature. Also, the size and location of the compartments provides for the placement and separation of different types of articles which either need to be separated from one another and permit lower support for the placement of heavy objects. The provision of such multi-compartments also prevents articles from being damaged or odor contaminated by other articles positioned in the same compartments. Casters are disposed on the outer periphery of the frame of the shopping cart, wherein the load in the multi-compartments remains between the casters to provide stability, and preventing tipping of the shopping cart.

Title: Method and apparatus for reducing femoral fractures
Inventor: THELAN SARAH L
IPC: A61F2/30
Filed: 2003-05-23
Abstract: An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A  femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps.  After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.
