Patent number: 5784936Abstract: An improved slice stacking device for a food slicing machine. The machine has a reciprocating carriage to which an elongated food product workpiece is mounted. The workpiece reciprocates through a cutting blade, forming a slice in each cycle. A stacking bed has a textured surface for unidirectional sliding resistance and is mounted to the carriage beneath the blade. Multiple curved fingers are rigidly mounted below an outfeed table and extend downwardly to contact, or be closely spaced from, the upper surface of the stacking bed during a portion of the reciprocation cycle. A slice removed from the workpiece lands on the stacking bed and passes beneath the fingers. During the rearward motion of the stacking bed, the slice is wiped from the stacking bed by the wiper fingers. Another embodiment includes a rake having downwardly extending tines positioned above the stacking bed. The tines extend downwardly into grooves between ridges on the stacking bed.Type: GrantFiled: May 28, 1996Date of Patent: July 28, 1998Assignee: J. E. Grote Company, Inc.Inventor: Robert W. King

Patent number: 5723319Abstract: Novel cell lines and methods are provided for inducibly expressing the Hepatitis B virus (HBV) genome within cultured cells. Cells are stably transformed with an HBV genome under control of an operator/promoter target sequence which can activate expression of the HBV genome when bound by a cognate transactivator protein. The cell lines are also stably transformed with a gene that encodes and expresses a suitable transactivator protein. Cells may be maintained under non-inducing conditions whereby the transactivator protein is unable to interact with the operator/promoter target sequence, so the HBV genome is not expressed. Under appropriate inducing conditions, the transactivator protein is enabled to interact with the operator/promoter target sequence, thereby activating expression of the HBV genome. The inducible system provides an effective and rapid cell-based assay to screen compounds for anti-hepadnaviral activity.Type: GrantFiled: June 5, 1995Date of Patent: March 3, 1998Assignees: Avid Therapeutics, Inc., Fox Chase Cancer CenterInventors: Robert W.

Patent number: 5388584Abstract: A shaft for an invasive bodily probe which includes a central core, a metal sheath surrounding the core and an outer elastomeric coating. A membrane formed of a textile layer disposed between two layers of a flexible, tough film is disposed between the sheath and the outer elastomeric coating. The membrane typically is formed of a woven material whose interstices have been completely filled by two layers of a urethane material. The membrane completely seals the sheath and core to protect the patient from electrical currents carried by wires within the core, and to prevent bacteria and fluids from being trapped in cuts in the shaft. The wires are also protected from damage from bodily fluids and cleaning solutions, since the core is sealed from the environment.Type: GrantFiled: April 15, 1994Date of Patent: February 14, 1995Assignee: Hewlett-Packard CompanyInventor: Robert W.

Patent number: 5029163Abstract: A synchronous protocol data formatter handles all 24-32 channels of a so-called primary rate version of a digital multiplexed interface or ISDN Primary Rates Interface for a communication system. The formatter relieves the host computer of the local area network of some highly specialized tasks, and, at the same time, provides the following augmented capabilities, which exceed those required by the C.C.I.T.T. standard, I.431:1. dynamic channel bandwidth allocation can assign arbitrary (even non-adjacent) time slots to create a super channel;2. a circular interrupt-queue in a shared memory enables the formatter and the host computer of the local area network to interact efficiently in updating and responding to changing conditions; and3. cyclical redundancy codes can be used on a more flexible basis than theretofore, e.g., can be generated upon only address and control fields for digitized voice signals, or, in a relay mode, can substitute an existing cyclical redundancy code to guard against memory errors.Type: GrantFiled: March 18, 1988Date of Patent: July 2, 1991Assignee: AT&T Bell LaboratoriesInventors: Phillip C.
