Title: Dismounting device for heavy load hoisting member
Inventor: TAKAI SEIICHIRO
IPC: B66C1/12
Filed: 1994-04-26
Granted: 1999-01-05
Abstract: ABSTRACT    A top wire 28 is set between a base 12 and a hook 31a of a crane 31. a bottom wire 32 whose foundation end is set to the base engages with a hoisting member engagement portion 11a of a heavy load 11, and a ring 32a at the front end of the wire 32 is fitted to a mast 17 erected on the base.  A slider 18 slidably fitted to the mast is raised by a first resilient body so that the top of the slider fits at least the top of the mast and slider lowering means 33 lowers a slider by overcoming the resilient force of the first resilient body.  Locking means temporarily fixes the slider lowering means while the slider lowers and unlocking means unlocks the locking means.     It is possible to automatically dismount a bottom hoisting member from a heavy load downed at a predetermined place. Moreover, it is possible to down a heavy load with any shape at a predetermined place without damaging a tension member and disuse the operation for engaging the tension member with the hook of the crane.

Abstract: A reciprocating pump particularly useful in ventilator apparatus includes a piston reciprocatable axially within a cylinder and dividing its interior into an inlet chamber and an outlet chamber, a wall fixed within the inlet chamber, and a drive housing fixed to the wall. The drive housing includes a motor, a rotor rotatable by the motor, a nut rotatable within the drive housing, and a screw threadedly coupled atone end to the nut and fixed at its opposite end to the piston. The piston is substantially unrestrained for axial and rotary movement such that forward and reverse rotation of the nut by the motor reciprocates the screw and the piston axially of the cylinder, and also permits the screw and the piston to rotate with respect to the cylinder to thereby even out wear between the piston and cylinder.

Abstract: A housing in a laser system encloses a cathode and a displaced anode and gases ionizable and reactive chemically when a voltage pulse produces a cathode-anode electrical discharge. Moving air cools the components (capacitors, thyratron and triggering circuitry) for producing the voltage pulses. The laser gas temperature is continuously regulated at a particular value whether or note there is an electrical discharge. The concentration of one of the gases in the chamber is regulated to values alternately on opposite sides of an optimal value to provide an optimal energy in each chemical reaction of the gases. The gases are recirculated as by a fan driven on a shaft by a pair of motors and are filtered during recirculation. The shaft speed is regulated at a particular value and the motor currents are regulated to be equal. Any ozone formed in a compartment holding the high voltage terminals is purged by passing a neutral gas (nitrogen) through the compartment to the atmosphere. The neutral gas is passed into the housing through a hose which also holds a high voltage wire in insulated relationship to other electrical components. A collar arrangement at one wire end provides for the introduction of voltage from the collar to the anode of the thyratron with the hose coupled to the housing and grounds the collar with the wire decoupled from the housing. The different high voltage components are sequentially tested for their operability by a system and method unique to this invention.

Abstract: Growth hormone polymeric controlled release systems are described wherein the growth hormone retains good biological activity and is released over an extended period of time following administration by injection. In the preferred embodiment, human growth hormone polymeric microspheres are made using very cold temperatures to freeze the polymer-growth hormone mixtures into polymeric microspheres with very high retention of biological activity and material. Sustained release of biologically active growth hormone is achieved when the microspheres are tested in vitro, extending over a period of greater than one day to several months. Altered release can be achieved by inclusion of degradation modifiers, pore forming agents, and stabilizers of the growth hormone.

Abstract: An implant assist apparatus is disclosed for implanting material such as a suture in tissue to reapproximate or reinforce the tissue. A cannula is provided having a hollow body and an open proximal and distal end. Point means is detachably fixed to the open proximal end of the cannula for penetrating tissue. A method of implanting the material in tissue for reapproximating or reinforcing the tissue with the implant assist apparatus is also disclosed whereby a length of the implant material is attached to a guide wire for partial containment within the cannula. The cannula with detachable point is passed into the tissue at an entry point remote from one side of the defect and out an exit point on the opposite side remote from the defect such that the distal end of the hollow body extends from the entry point and a proximal end extends from the exit point. The detachable point is removed from the cannula and a guide wire with implant material attached is drawn out of the proximal end of the hollow body until the implant material is exposed at both the distal and proximal ends of the hollow body. Thereafter, the cannula is withdrawn from the tissue leaving the implant material in place and the implant material is anchored to reapproximate or reinforce the defect.

Granted: 1999-08-24
Abstract: A rotating Carrousel having four mould cavities equally spaced at ninety degrees from each other. The moulds are open vertically to the sky and in the opposite direction. The moulds are on the same pitch circle from the center of the axis. The rotary table "carrousel" is positively locked at each ninety degree turn. When the table is locked in position each station is in its position. The hopper containing the pre granulated soil is mounted stationary above the number one station. The hopper is fed by a screw conveyor from a hammer mill which breaks up the dug out soil into a uniform granulate. This is most important for the manufacture of high quality adobe bricks. When the hopper has filled the mould cavity the carousel is turned ninety degrees and the filling process is repeated, at the same time the ram at number two station compresses the soil into a high density adobe block. On a further ninety degree turn both operations are repeated, and at the same time at the number three station, a hydraulically operated ram ejects the completed adobe block. The carousel is mounted on a heavy frame suitable to sustain the hydraulic forces of the compression and ejecting rams.

Abstract: A sectional structure is provided herein. Such structure includes a glazier' s strip section having a first side brace flange for bracing one side of a glass pan e. Such structure further includes a casing section having a second side brace flange for bracing the other side of the glass pane. Such structure further includes a bottom rest which is positioned at substantially a right angle with respect to the second side brace flange, th e glass pane being disposed in a space which is defined by the first side brace flange, the second side brace flange and the bottom rest. The glazier's strip section and the casing secti on are formed mutually interlockable. They have fixing means for detachably attaching the glazier's strip section to the casing section. The fixing means includes a first locking cla w which is formed on the casing section, and a second locking claw which is formed on t he glazier's strip section for interlocking with the first locking claw. Such structure further includes a first brace member, which is formed on the casing section, and a second brac e member, which is formed on the glazier's strip section. The second brace member brac es against the first brace member which forms a pivot between the glazier's strip section a nd the casing section. In this manner the glazier's strip section is pivotable between a locked position and an unlocked position, with the first brace member and the second brace membe r being urged against each other. The glazier's strip section is configured to be turnable around a pivot which is constituted by cooperation of the first brace member and the second brace member. This cooperation serves to press the first side brace flange against a surface of the glass pane into the locked position. Furthermore, by such action, the first locking claws and the second locking claws become interlocked.
