Title: Method and apparatus for pre-forming spout in seal flexible pouch
Inventor: JAMISON MARK D
IPC: B65B61/18
Filed: 1987-12-31
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE         A pre-forming technique for web material utilized to make flexible pouches for fluent products comestibles and non-comestibles in form-and fill equipment of well known type characterized by the initial stretching displacement of each web from its normal plane and in a configuration corresponding to the ultimate spout configuration prior to forming of the pouch with the spout therein, thereby preventing undesired blockage of the spout by unintended adherence of the packaging film in the spout zone during sealing operations.  The technique is especially desirable in pouches having a unique and complex reversely curved discharge passageway.

Title: Method of bonding structural support channels to a panel
Inventor: WENCLEY STANLEY E
IPC: E04C2/00
Filed: 1988-01-20
Granted: 1992-08-18
Abstract: 676.014 ABSTRACT METHOD OF BONDING STRUCTURAL SUPPORT CHANNELS TO A PANEL   A method of bonding rigid structural support members to a gypsum or fiberboard panel to form a structural building module. The method involves applying a polyurethane adhesive as a liquid by high pressure stream into a space formed at the juncture of the support members and the panel. The space is established by providing a plurality of spaced feet on one planar side of the support members. The support members include either integrally formed feet, which are placed on the panel, or non-integral feet that are inserted between the support members and the panels. The support members may include holes on the surface bonded to the panel in a face to face relationship or on vertical surfaces in close proximity to the panel through which foam may expand and form a mechanical interlock with the support members. The support members may be metal channels or wood members. The structural building module provides an increased strength bonded structure without the use of nails or other fasteners. The film also provides a thermal insulating layer between the structural support members and the panels.

Title: Semipermeable nerve guidance channels
Inventor: VALENTINI ROBERT F
IPC: A61F2/00

Granted: 1991-12-31
Abstract: SEMIPERMEABLE NERVE GUIDANCE CHANNELS                         ABSTRACT Medical devices and methods employing semipermeable materials, such as acrylic copolymers, polyurethane isocyanate, and other biocompatible semipermeable polymers, are disclosed for use as guidance channels in regenerating nerves.  The devices can be formed by tubular semipermeable conduits adapted to receive the ends of a severed or damaged nerve.  The tubular conduits define lumens through which axons can regenerate to restore motor and/or sensory functions. The guidance materials are chosen such that they are capable of allowing the diffusion of nutrients and other metabolites to the regenerating nerve site while excluding fibroblasts and other scar-forming cells.  In particular, tubular channels which have a smooth inner surface and longitudinally oriented trabeculae result in significantly larger regenerated nerve cables and higher numbers of regenerated myelinated axons.

Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for classifying broadcast information first receives the broadcast information and processes it to provide a plurality of a low bandwidth analyzed waveforms.  The analyzed waveforms are used to generate a spectragram which is then compared with a plurality of reference spectragrams stored in a first stage reference library.  The first stage reference spectragrams are then queued in order of their similarity to the generated spectragram.  Next; a plurality of second stage reference patterns, which correspond to the first stage reference spectragrams, are correlated with one of the analyzed waveforms in the queueing order established previously.  A correlation value is provided for each second stage reference pattern stored in, the second stage reference library.  When it is determined that a correlation value exceeds the threshold value, a recognition is declared and the broadcast information is classified as similar to the second stage reference pattern whose corre-lation value exceeds the threshold.  The analyzed waveform used in the second stage classification may be time warped to account for speed fluctuations in the broadcast information.

Title: Line reeving system for earth drilling machine
Inventor: WILLIS CLYDE A
IPC: E21B19/08
Filed: 1988-09-01
Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE     An earth drilling machine includes a crown block assembly, a travelling block assembly and a drawworks.  The drawworks includes a drum which rotates about a drum axis.  The drum axis is oriented at right angles to a fast line plane defined by a fast line sheave included in the crown block assembly.  In this way, the fleet angle between the drum and the fast line sheave is kept substantially equal to zero.  Various sheave arrangements are described which combine proper selection of sheave pitch diameter, sheave axis angle, and sheave placement to ensure that the fleet angle of all of the sections of line extending between the crown block assembly and the travelling block assembly are reeved with a fleet angle exactly equal to zero.  In this way line wear is reduced and the height, weight and windage of the mast are all minimized.

Abstract: ABSTRACT    An eyetracker  for  moving  the path of  a  laser  beam  in response  to  patient  eye  movement  comprises  a  visual  light source on which the patient can fixate to bring the visual axis of the eye into a reference alignment with the optical axis of the light source.   A laser source, having its beam coaxially aligned with the optical axis of the light source, cuts a mark onto the cornea of the eye when the eye is in the reference alignment.  An infrared optical system monitors movement of the mark to generate an error signal which is proportional to any movement of the mark out of the reference alignment.  Means are also provided by the eyetracker to move the path of the laser beam back  into the reference  alignment to reduce the error signal to a null.     PAT:  12051-03

Granted: 1993-01-05
Abstract: ABSTRACT         On a table, a support element is provided on the table leg and below the tabletop.  This support element is pivotable about the vertical axis of the table leg.  When the support element is pivoted outward, it can serve as a support for a tabletop and is formed accordingly.  The tabletop has an elongated engagement element on its underside, which element upon connection positively engages the inside of a corresponding elongated recess of the support element.  A table connection formed in this way is very stable, and makes it possible for the thus-formed table arrangement to be moved about practically like a rigid unit.  Also, it is possible for a single person without additional help, using this connection device, to couple one table to an adjacent tabletop.

Title: Aircraft propeller speed control
Inventor: BENNETT GEORGE W
IPC: B64D31/06

Granted: 1992-07-28
Abstract: AIRCRAFT PROPELLER SPEED CONTROL             ABSTRACT OF THE DISCLOSURE The invention concerns a control for an aircraft propeller. During operation in reverse pitch, as occurs upon thrust reversal during a landing maneuver; the speed of the propeller is controlled by adjusting pitch of the propeller, in order to prevent overspeeding.  Further, during the transition period while the propeller is converting from forward pitch to reverse pitch, the propeller presents a light load to the engine.  At this time, fuel flow to the engine is limited in order to restrict delivery of energy to the propeller, again, for the purposes of preventing overspeeding.
