Title: Safety lock for a hoisting mechanism that ascends and descends a cable
Inventor: MAULDIN WILLIAM E
IPC: B60T8/24
Filed: 1976-06-25
Granted: 1978-12-05
Abstract: A novel safety lock that includes an activation device and a latching device, these devices cooperating with the cable that passes through the lock.  The activation device includes a guide pulley rotatably fixed to a mounting plate, a spring loaded pressure roller adapted to press the cable into operating engagement therewith, and a series of centrifugally activated arms positioned about the axis of the guide pulley.  The latching device includes a lock block fixed to the mounting plate, and a spring loaded lock wheel  mounted for eccentric rotation, the lock wheel being adapted t? lock the cable against the lock block then activated.  A separate release lever pivotally fixed to the mounting plate is spring loaded in one direction, and a separate latch lever pivotally fixed to the mounting plate is spring loaded in an opposite direction, the latch lever having a latc? pin adapted to interengage with a seat defined by the release lever when the safety lock is in the set or unactivated position. Also, the latch pin interengages a seat in the lock wheel to retain same in the spring loaded or inactivated attitude.  The head of the release arm is disposed relative to the per?phery of the centrifugally activated arms such that any outward motion of those arms (e.g., due to centrifugal force induced by a rapid fall of the safety lock down the cable) will cause at least one of the arms to trip the  release lever, thereby removing the latch pin from interengagement with the release lever.  At this point the spring loaded latch lever removes the latch pin from interengagement with the lock wheel, thereby allowing the lock wheel to rotate and securely grip the cable between the lock wheel and the lock block.

Abstract: ABSTRACT OF THE DISCLOSURE      In a composite beam, a connecting element interconnects a concrete slab and a downwardly depending structural steel member. The connecting element is L-shaped having an elongated base member which is secured by one or more fastening elements to the structural steel member and an elongated anchor strap extending angularly from the base member and incorporated into the concrete slab. Supporting webs are secured to and extend between the base member and anchor strap. The part of the base member encircling the openings through which the fastening elements pass is deformed to provide rounded recesses. The anchor strap can be made more rigid by forming a corrugation-like recess extending in the elongated direction of the strap. When a force is applied to the anchor strap causing it to move angularly away from the base member, the support webs cause the adjacent surfaces of the base member to act as deformation zones relieving the force on the connection between the base member and the structural steel member.

Abstract: ABSTRACT OF THE DISCLOSURE A motor controller providing a disconnect and a single set of movable contacts to provide operation and pro-tection of a motor and associated circuitry over a complete range of possible currents.  Plug-in modules for a circuit disconnect, a solid state overload relay, and an instantaneous trip unit are provided.  The disclosed integral modular motor controller consists of five major components:  (1) an isolator switch, (2) arc chambers, (3) a linear slot motor drive, (4) a drive operator, and (5) a solid state control.  For a normal motor starting operation and for fault currents up to a pre-determined value, such as 1200 amperes, an electromagnetic actuator is used to open the contacts a relatively small distance such as .25 inch.  For higher fault currents a drive or linear slot motor opens the contacts to a greater separation such as 1 inch.  The disclosed modular integral motor controller utilizes a disconnecting switch connected in series with a movable bridging contact arm on which arm mounted a pair of spaced apart movable contacts aligned to engage a pair of stationary contacts when the motor controller is in the closed position to complete an electric circuit to the controlled motor.  The bridging contact arm is provided with two open positions; one for use in motor control and relatively low fault currents, wherein relatively small contact separation is involved, and a second open position used during high fault currents and current limiting situations, wherein the movable contacts are separated from the stationary contacts by a relatively large separation.

Abstract: ABSTRACT OF THE DISCLOSURE           In a system in which a light emitting element such as a semicon-ductor laser, light emitting diode or the like is modulated directly by a drive current corresponding to an input modulation signal, the light output for a given drive current gradually decreases and where the pulse width of the drive current is sufficiently wide the output pulse sage.  These effects are due to thermal causes.  The invention involves compensating for the decrease and sag.  Various circuits providing this compensation are disclosed. One circuit ensures that the light emitting element is driven by a drive current corresponding to a composite signal composed of an input modulation signal and its integrated value.  A D.C. component of appropriate magnitude may also be imposed on the drive current.

Abstract: Application for Patent of Howard D.W. Hill for PULSED RF EXCITED SPECTROMETER HAVING IMPROVED PULSE WIDTH CONTROL        ABSTRACT OF THE DISCLOSURE    RF excitation for a spectrometer is obtained by pulse width modulating an RF carrier to produce the desired broad-band RF exciting spectrum.  The RF excitation includes a train of composite RF pulses, each composite pulse having a primary pulse portion of a first RF phase and a second pulse portion of a second RF phase opposite that of the first.  In this manner, the finite rise and fall times of the primary pulse portion are compensated for by the corresponding rise and fall times of the secondary pulse portion.  The primary pulse portion is lengthened by an amount equal to the secondary pulse portion so that the secondary pulse portion cancels the added primary pulse portion. In a spectrometer the compensating second pulse component removes certain undesired side bands of the RF excitation caused by the finite rise and fall times of the applied RF pulses.  The compensating second pulse component removes certain undesired side bands associated with each of the resonant lines of the excited resonance spectrum, thereby simplifying the resonance spectrum of the sample under analysis, particularly for wide band RF excitation.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention is directed to a stretch-wrap machine wherein a motive unit carries a stretch-wrap unit around material to be wrapped.  One approach to retaining a number of packages on a pallet has been steel banding.  Steel bands were placed around the packages and the pallet and the bands tightened and clamped.  The problem with steel banding is that loads can be crushed.  Furthermore, the steel bands are difficult and dangerous to handle.  Shrink wrapping has also been used, but requires special equipment for causing the shrinkage.  Further, it cannot be used in cold rooms or other areas where high heat loads are objec-tionable.  Also, it cannot be used over polyethylene wrapped pack-ages because of sticking between the shrink wrap material and such packages.  Machines which wrap stretch-material have been developed.          However, these machines cannot be effective unless the load is small enough to fit on a turntable.  To overcome these disadvantages, the present invention provides a motive unit which carries stretch wrap unit around stationary material to be wrapped.  The motive unit Is preferably self-propelled and may be self-guided by means of a track follower, although manual motive unit guide controls can be pro-vided.  Alternatively, the motive unit may be self-propelled and biased to be self-guided around the unit to be wrapped.  In such embodiment, a follower wheel contacts the unit to be wrapped and controls its steering.  A propulsion urges the motive unit toward the material to be wrapped.
