Title: Dock leveler in which the ramp is raised and lowered using an inflatable member
Inventor: HODGES CHARLES H
IPC: B65G69/28
Filed: 1995-01-30
Granted: 2003-10-21
Abstract: A dock leveler including a ramp movable between a raised position and a lowered position is moved to its raised position by inflation of an inflatable member, such as an airbag supported beneath the ramp by a support assembly. The support assembly is removably mounted below the ramp at its rearward end, and its forward end is provided with wheels which engage the floor of the pit within which the dockleveler is mounted. A fan is mount-ed to the support adjacent its rearward end, and includes an outlet communicating through the support with the interior of the airbag. The airbag, support and fan are assembled into a subassembly which is removable as a unit from below the ramp. A lifting tool is employed to raise the forward end of the support assembly, either for cleaning or for use in mounting a pair of auxiliary wheel assemblies to the support assembly. The auxiliary wheel assemblies are employed to disengage the airbag, support and fan subassembly from the dock leveler and to facili-tate withdrawal of the subassembly for servicing or the like.

Abstract: An inner handle assembly of a door lock includes a handle with an axle. A mounting cap has an axial hole for passage of the axle and a through-hole offset from the axial hole. A spindle driving plate has a central hole engaging fittingly a spindle of the door lock. A manually operable lock unit has a button member extending outwardly through the through-hole and mounted for movement in an axial direction between locking and unlocking positions, and an engagement member in connection with the button member. The engagement member engages the spindle driving plate for locking against rotation of the spindle driving plate when the lock unit is at the locking position. A rotary member is mounted on the axle within the mounting cap for rotating simultaneously the axle. The rotary member moves axially and outwardly the engagement member to disengage from the spindle driving plate when the axle is turned to rotate the rotary member. The axle retards rotation of the spindle driving plate so that the spindle driving plate starts to rotate after the lock unit is moved to the unlocking position.

Abstract: Coke deposits are removed from particulates by combustion in a regenerator by a process in which air is initially used as the oxidant. The combustion gas is subjected to a separation process to remove nitrogen therefrom, and the remaining carbon dioxide-enriched gas stream is recycled to the regenerator together whilesubstantially pure oxygen is introduced into the regenerator. As the level of carbon dioxide in the system increases, the amount of air being introduced into the regenerator is gradually reduced and, in compensation, the amount of oxygen flowing to the regenerator is gradually increased. Eventually, part or all of the air is replaced by oxygen and carbon dioxide recycle gas, and the level of oxygen and carbon dioxide are regulated to maintain the desired temperature in the regenerator.

Abstract: An optical fiber LED assembly for coupling the light from a can-shaped light emitting element to an optical fiber via a rod lens with distributed refractive index provides improved stability by controlling the deterioration with the lapse of time.  The optical fiber LED assembly employs a can-shaped light emitting element which radiates light through a transparent aperture-covering plate at the top of the can.  The can-shaped light emitting element is supported by a first cylindrical holder.  A second cylindrical holder supports a rod lens with distributed refractive index at one end thereof and accepts and supports the distal end of an optical fiber ferrule.  The second cylindrical holder is inserted and fixed in the first cylindrical holder, the rod lens with distributed refractive index being directed toward the transparent aperture-covering plate of the light emitting element.  A seal ring is inserted between the light emitting element and the second holder in the first holder and a refractive index matching agent is hermetically charged in the space formed by the transparent aperture-covering plate and the second holder.

Title: Radon gas measurement apparatus having alpha particle-detecting photovoltaic photodiode surrounded by porous pressed metal daughter filter electrically charged as po-218 ion accelerator
Inventor: DIAMONDIS PETER J
IPC: G01T1/178
Filed: 1995-11-01
Granted: 2003-01-21
Abstract: A radon detector employs an electrically charged pressed, porous metal filter that allows radon gas diffusion, while blocking ambient light, so that it readily traps both attached and unattached Po-214 and Po-218 ions, that may be present in gas passing through the filter, the filter being charged positively relative to an unbiased PN junction of a photodiode detector within a detection chamber. As a consequence, radon daughter products are prevented from corrupting the radon measurement. Since no voltage differential is applied across its PN junction, the photodiode detector operates in a photovoltaic mode, which avoids the problem of Schottky noise, producing low amplitude current pulses, which are amplified, passband filtered and thresholded to provide well-defined pulses that are counted over a given measurement interval and converted to radon concentration in terms of picocuries per liter.

Abstract: A pump (2) including a submersible motor (10) sealed within a motor chamber (11), an impeller (6) rotatably mounted in an impeller chamber (12), and motor and impeller shafts (72, 76) coupled to one another to interconnect the motor and impeller. The impeller pumps fluid from the impeller chamber into the motor chamber where the fluid flows around the motor to cool the motor and muffle the motor noise before being discharged from the pump. The impeller shaft (76) is rotatably mounted in a bearing (90) fixed to an impeller housing (4) and having grooves (106) facing the impeller shaft (76) and providing fluid communication between the impeller and motor chambers. Fluid flows into the grooves from the impeller or motor chamber depending on the pressure gradient across the bearing, which varies according to downstream pump conditions (e.g., pressure). As the impeller shaft continues to rotate, fluid from the grooves forms a thin lubricating film in a clearance space provided between the impeller shaft and bearing. With this construction, the need for conventional impeller shaft seals is eliminated.

Abstract: A method for twisting a pair of moving strands uses a winder assembly 510, which is mounted on a first shaft 140 and rotates around a cylindrical drum 110.Twisted wire is wrapped in adjacent convolutions around an exterior surface of the cylindrical drum, which is mounted on a second shaft 150. The exterior surface is energized to advance the convolutions from its input end to its output end; and an unwinder assembly 520 is mounted on a third shaft 160 at the output end of the drum. The shafts are coaxial with each other and each is capable of independent rotational movement. The volume of strand material stored on the drum may be varied by changing the relative rotational speeds and directions of the different shafts. A twist in one direction is imparted onto the strand pair when the number of convolutions stored on the drum is increased; and a twist in the opposite direction is imparted onto the strand pair when the number of convolutions stored on the drum is decreased. By periodically changing the rotation direction of the winder and/or the unwinder, an S-Z twist pattern is imparted onto the strand pair.
