A thread handling device is disclosed in a type 301 lockstitch rotary hook loop taker sewing machine having a three-to-one hook to arm shaft ratio for controlling and metering slack needle thread prior to needle penetration to prevent the thread from wrapping around the point of the needle, which could prevent loop seizure, break the thread, or interfere with correct stitch formation. The thread is guided between two stationary members, with the controller between the members, the controller com...

Mushrooms harvested from a growing bed are deposited on a carrier having a plurality of individual recesses each for receiving an individual mushroom by supporting the under-side of the cap with the stalk projecting downwardly. The carrier, when fully loaded with mushrooms, is moved into a compartment of a multi-compartmented storage structure configured to allow the flow of air therethrough. The structure is then moved into a cold room so that all of the carried mushrooms are cooled down to the...

This invention relates to methods of minimizing catalyst degradation during the handling of a catalyst used in a slurry phase reactor. The methods include catalyst handling steps such as catalyst loading into a slurry phase reactor, slurry phase reactor start-up, slurry phase reactor shut-down, and slurry phase reactor unloading when catalyst reloading is envisaged. In the method of loading the slurry phase reactor, a slurry of wax and catalyst is formed in a loading vessel. Clean molten wax is ...

A slag handling apparatus and method are disclosed wherein slag is received at an elevated temperature of about 3000.degree. F. and an elevated pressure of about 450 pounds per square inch and is handled so that it may be transported at atmospheric pressures and low temperatures of the order of 100.degree.-200.degree. F. The slag is sequentially fractured and ground by a grinder while descending downwardly through a column of water in a series of vessels.

A handling apparatus adapted for transferring machined pieces from one station to another. A hollow cylindrical arm is mounted vertically movable upon a frame which is laterally movable along a guide rail. Within the hollow arm are positioned an operating rod and a coaxial inner cylinder with a spring disposed between the ends of the inner cylinder and the cylindrical arm for biasing the inner cylindrical arm downwardly. A clamper including fingers which are spreadable by operation of the operat...

In the context of the handling of cryogenic materials, particularly liquefied natural gas (LNG), in marine loading systems, coaxial ducting links various plant sites of the system to provide in the one link both liquid transfer ducting and a return ducting for vapor of the liquid. Return of this vapor in the outer ducting helps thermally insulate the liquid in the inner ducting from the surrounding. The ducting is made up of rigid coaxial pipes swivellably connected together by swivel joints hav...

Saturation handling for preventing a power amplifier from going into a saturation condition is disclosed.

A method is provided for handling failures in a computer system including a compliance checking system in a computer network. In response to a client computer failing to obtain a compliance check, a determination is made as to a category of an error that at least partially caused the failure in obtaining the compliance check. As a result, the method includes performing an action to at least partially based on the determined category of the error. In some instances, the action can include allowin...

A transportable container for particulate solid material and receiving means for the container which is adapted to removably receive the container and which is capable of being actuated to promote flow of material from the container.

A tray is adapted to be supported on an elevator mechanism and moves vertically by the elevator mechanism to pick up a shingled array of signatures which are supported on edge in an inclined position adjacent the elevator mechanism. The tray includes a generally horizontally extending support portion adapted to engage the lower edges of the signatures as the tray is raised. A member located at one end of the tray has an inclined surface against which the last signature at one end of the tray res...
