Abstract: A surgical instrument (50) is provided which is insertable through an endoscopic tube to enable a surgeon to perform a surgical technique inside a body cavity. The surgical instrument includes a shaft with a pivotally mounted tip (60) attached thereto, the shaft extending from a handle (80) for gripping the instrument for insertion to the body cavity. The tip (60) of the shaft is adjustable to different angular orientations relative to the support shaft (70) and is rotatable at any angular orientation of the tip. The support shaft (70) may be rotatable about its longitudinal axis relative to the handle (80), or it may be fixed with respect to the handle, in which case the handle may be rotated to rotate the shaft inside the body cavity. The surgical instrument comprises an endoscopic stapling device and the tip of the instrument comprises a staple cartridge (100) which is rotatable 360° about its axes after the cartridge has been articulated with respect to the support shaft. An improved device for articulating the shaft tip (60) is also provided in which a control knob is mounted to the support shaft for providing sweeping articulation of the shaft tip. Separate actuator mechanisms (82,84) are provided on the handle to control the pivotal movement of the shaft tip, as well as the rotation of the shaft tip and the rotation of the support shaft.

Inventor: GROSBACH LYLE EDWIN
IPC: G06F1/10
Filed: 1994-09-23
Abstract: The ability to harmonize the activities of individual computer system components with control signals is key to the operation of any computer system. Examples of this need for control include the need to write data to multiple registers on the same clock cycle, the need to clear values on multiple entities on the same clock cycle, and the need to stop and start the master clock pulse train itself. In the past, providing this control was not a problem because control signals could be reliably sent to all the timing dependent components within a single cycle of the master clock pulse train. This control methodology is called "single cycle control." Today, however, single cycle control is not trustworthy in all situations. Master clock pulse trains are so fast that single cycle control is no longer reliable when timing dependent components reside in locations distant from the control signal generating circuitry. The present invention provides reliable control in all cases, including the situation where a master clock pulse train is so fast that single cycle control is not viable.

Abstract: This invention relates to immunogenic luteinizing hormone releasing hormone (LHRH) peptides that lead to suppression of LHRH activity in males or females. When male rats are immunized with these peptides, serum testosterone drops and androgen-dependent organs atrophy significantly. These peptides are useful for inducing infertility and for treating prostatic hyperplasia, androgen-dependent carcinoma, prostatic carcinoma and testicular carcinoma in males. In females, the peptides are useful for treating endometriosis, benign uterine tumors, recurrent functional ovarian cysts and (severe) premenstrual syndrome as well as prevention or treatment of estrogen-dependent breast cancer. The subject peptides contain a helper T cell epitope and have LHRH at the C terminus. The helper T cell epitope aids in stimulating the immune response against LHRH. The peptides, optionally contain an invasin domain which acts as a general immune stimulator. In another aspect this invention relates to immunogenic synthetic peptides having an invasin domain, a helper T cell epitope and a peptide hapten and methods of using these peptides to treat disease or provide protective immunity. The peptide haptens of the invention include LHRH, amylin, gastrin, gastrin releasing peptide, IgE CH4 peptide, Chlamydia MOMP peptides, HIV V3 peptides and Plasmodium berghei.

Abstract: A security document is produced from a paper substrate having invisible hydrophobic toner blended into the paper. The clear toner is produced by milling (11) and classifying (12) a polyester resin, mixing it with a silica flowing agent (13), and then electrostatically imaging the toner (16) onto the paper substrate. An infrared absorbing or UV responsive dye may be added to the toner so that it is visible under infrared/ultraviolet light respectively. When applied to the paper the toner is snow white, but after infrared heat fusing (18) it blends into the paper and is substantially invisible. The security indicia is easily made visible by passing a conventional marker nib over it, or other mechanism for applying a water based low concentrate colored ink (20) which is readily absorbed by the surrounding paper, but not by the hydrophobic security indicia.

Abstract: A two-phase liquid cooling system has a container structure that has at least one wall with sufficient flexibility that the wall expands as the coolant vapor expands thereby maintaining the internal container pressure substantially the same as the ambient environmental pressure. Coolant boiling overshoot is reduced by allowing residual gases to remain in the cooling system. More particularly, sufficient residual gas is maintained in the system so that some of the gas dissolves in the liquid coolant when the device is not operating and is at ambient temperature. During warm-up, the residual gas comes out of solution and creates nucleation sites that initiate boiling and prevent overshoot. Additional nucleation sites can also be added to reduce overshoot by treating the inside surfaces of the container structure, for example by laser machining, to create nucleation sites.
