Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for reducing ice forces on a marine structure erected in a body of water which becomes frozen through natural weather conditions.  The structure has a low-ice-adhesional wall forming its perimetrical surface in the zone where natural ice will freeze onto or impinge against the structure.  Enclosed chambers are built within the struc-ture and may be in heat-transmitting relationship with the outer wall.  Heat is applied to the chambers to heat and maintain the outer wall at a temperature above the melting point of the natural ice occurring in the water around it.  In a preferred embodiment, the marine structure is formed with a heated wall which slopes upwardly and inwardly in the area of ice contact to provide a ramp-like surface upon which sheet of ice will be forced with reduced friction as it moves against the structure.  Thus, an edge of the sheet of ice will be prevented from strongly adhering to the structure either initially or subsequently.  This sufficiently weakened ice-to-surface bond without heat or reduced heat to the outer wall allows the ice sheet to be lifted above its normal position on the water surface as the ice moves against the structure, causing the sheet to break any weak surface bond so it can be bent and fractured as it rides by the coated ramp-like surface and thereby reducing the force imposed by it on the structure.          An alternate embodiment for reducing ice forces takes the form of a fully or partially coated cone or a cone made from material having low ice-adhesion properties. This embodiment may or may not be in combination with a heated surface.

Abstract: Abstract of the Disclosure Alignment apparatus and method for aligning a pair of machines having first and second rotating shafts in a machine train with at least one flexible coupling intercon-necting the first and second shafts.  The flexible coupling has at least one member connected to one of the shafts and is capable of accommodating at least some misalignment of the first and second shafts.  One of the first and second shafts is considered as a reference shaft and the other of said first and second shafts is considered as a movable shaft.  Means is carried by the shafts having surfaces spaced apart circumferentially with respect to the axis of rotation of the shafts which represent the orientation of one of said shafts and serve as reference surfaces. Paddle means is carried by the flexible coupling and has surfaces spaced apart circumferentially with respect to the axis of rotation of the shafts and representing the orientation of the one member of the flexible coupling.  Probe means is pro-vided for sensing the position of the reference surfaces and the last named surfaces to provide information on the gap or spacing between the probe means and the surfaces.  The infor-mation supplied by the probe is utilized for giving an indica-tion of the axial motion of the machines, both steady state and dynamically and both relatively and absolutely.  In addi-tion, the apparatus provides net coupling hub motion of each machine due to any dynamic motion of each rotor, such as that due to fixed bows, thermal bows, unbalance bows and other action at rotative speed in a forward direction and also that due to any other action at other than rotative speed in a for-ward direction such as oil whirl, reexcitation of balance resonances and other actions that create shaft motions.

Title: Apparatus and method for repairing elongated flexible strips having damaged sprocket feed holes along the edge thereof
Inventor: STANFIELD JAMES S
IPC: G03D15/04

Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates to repair of elongated, flexible perforated strips such as tape, film and the like.  Attempts have been made at repairing sections of damaged film by laminating repair tape over the damaged film, such attempts have not  proved acceptable.  Motion picture film generally shrinks when it is developed and also with age and with changes in atmospheric conditions.  The pre-punched sprocket feed holes quickly become disaligned with the original film sprocket feed holes.  A further problem is that the repair tape covers not only the edge of the film containing the sprocket feed holes, but also the entire picture frame.  This hinders light transmission and picture definition and clarity is appreciably reduced.  With the present invention the repair tape is applied to the strip in a simple, reliable, and effective manner, and permits long lengths of damaged strip to be quickly and easily repaired.  Film to be repaired by the present invention is fed continu-ously from a supply reel through a pair of straightening and flattening rollers to a repair station comprising a pressure roller cooperating with a sprocket roller to automatically and precisely align the preformed feed holes of the tape with the damaged feed hole locations of the film and to bond the tape and film together in the aligned condition.  From the repair station, the laminated tape and film pass through a pair of cooperating rollers to more firmly bond the tape and film preparatory to collection on a take-up reel.

Abstract: ABSTRACT OF THE DISCLOSURE A central dictation system including a plurality of remote dictate stations, a plurality of record/reproduce stations and a plurality of trans-cribing stations operatively connected to respective ones of the record/re-produce stations.  Any one of the remote dictate stations is capable of communicating with any one of the record/reproduce stations so as to ex-ecute a dictate and/or playback operation.  When a record/reproduce station is communicating with a dictate station, the remaining dictate stations are prevented from gaining access to that communicating record-reproduce station.  A transcribing operation can be performed substantially inde-pendent of the dictate and/or playback operation.  Code recording appara-tus is provided to automatically record a predetermined code signal at the conclusion of each dictated message.  This recorded code signal prevents the recorded message from being reviewed or erased by the subsequent use of a remote dictate station.  During a transcribing operation, these pre-determined code signals are detected and are used to implement a scanning operation so that a desired one of the dictated messages can be transcribed, notwithstanding the particular sequence in which that message had been re-corded.  The record medium may comprise a magnetic tape and noise suppressing circuitry is provided to suppress the inherent tape hiss attending a play-back operation when the tape is driven at a very slow speed,  In an embodi-ment wherein the dictation and transcription transducing sites are spaced apart, apparatus is provided to insure that a sufficient amount of magnetic tape is furnished to the transcription transducer site to permit an entire dictated message to be transcribed.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a hood assembly for an electrical connector. Heretofore, hood assemblies were primarily structures which could be slid over an electrical connector and clamped about an incoming cable.  It has become highly desirable to have a hood assembly which, in addition to providing protection for an electrical connector, may be utilized to clamp and properly distribute both incoming and outgoing electrical conductors.  The present invention provides a new and improved hood assembly for an electrical connector which will properly distribute and clamp both the incoming and outgoing electrical conductors of a tapped conductor arrangement.  The hood assembly includes a pair of complementary releasably engageable hollow housing shells.  Each of the shells includes a longitudinally extending inwardly projecting rail or rib immediately adjacent the strain relief mechanism of the connector, or a strain relief adapter mounted on the connector, to press against the individual conductors and provide additional strain relief.  The shells are provided with complimentary recesses which are cooperable to form openings for passing bundles of conductors or individual conductors therethrough, the edges of the openings also functioning to clamp the conductors when the shells are connected together,  The recesses may be provided at different locations on the housing assembly for various conductor distribution arrangements including an L-shaped arrangement and a T-shaped arrangement.
