International Classification:

B65B 51/10

US Classification:

156378

Abstract:

The problems associated with the prior art have been overcome by the present invention, which describes a tubular heating element having a more reliable and accurate temperature monitoring system. The tubular heating element has a thermocouple attached to its exterior surface, in close proximity to the cutting and sealing portion of the tubular heating element. In addition to improving the accuracy of the temperature measurement, this technique reduces electromagnetic interference caused by the interaction between the heating wire and the thermocouple.

Assignee:

Shanklin Corporation - Ayer MA

International Classification:

B65B 906

US Classification:

53 28

Abstract:

An automatic L-sealer is arranged to pass product, including fragile items and loose piles of stacked paper, tiles or similar flat articles, through the machine without abrupt drops or changes in support level for the product to avoid breakage or upsetting of the pile. In the case of stacked loose flat articles an infeed conveyor deposits a package on an air table and an insertion arm progresses the package through the overwrap station to a sealing area where the L-seal completes and separates the overwrapped package. The sealing area includes a discharge conveyor pivoted at its discharge end and elevated at the end adjacent the air table to transfer the overwrapped package without an abrupt drop but is thereafter lowered during the sealing cycle to permit the seals to be made midway of the height of the package. The insertion arm retracts out of the path of package flow during its return stroke permitting infeeding of the next package to be initiated prior to the completion of the return stroke. Automatic controls are provided to coordinate the various operations including starting the infeed conveyor while the insertion arm is returning to its starting position.

F22B 1500

US Classification:

208159

Abstract:

The invention provides an improved method and apparatus for operating a fluidized bed chemical processing unit of the type having steam generating coils, so as to reduce the occurrence of thermally-induced stresses in the coils and thereby extend the useful life of the coils. The invention involves causing the tube wall temperature of a coil being brought into service to be lowered from bed temperature prior to initiating water flow in the coil, so as to decrease the thermal shock temperature gradient and thereby reduce the magnitude of thermally-induced stress in the coil. The invention utilizes a base coil in addition to the steam generating coil that is being cycled, and a pair of steam drums which operate at a pressure differential. The method involves generating saturated steam in the base coil and superheating the saturated steam in the coil being brought on line. Steam is directed from one drum to the other in a predetermined manner so as to provide proper temperature control of the coil being cycled.
