A system and method for isothermally distributing a temperature across a semiconductor device. A furnace assembly is provided, which includes a processing tube configured to removably receive a wafer carrier having a full compliment of semiconductor wafers. A heating assembly is provided which can include a heating element positioned to heat air or other gases allowed to enter the process tube. The furnace assembly and process tube are capable of being vertically raised and lowered into a positi...

A batch delivery system that maximizes the amount of material to be transferred from a material source to a material destination by determining whether a primary total and/or a secondary total from a flowmeter have reached a primary target and a secondary target. In one embodiment of the invention, the primary target and the secondary target are mass, volume, and/or net solid.

Batch pasteurizers are disclosed for processing milk, colostrum and other dairy products. The pasteurizers comprise inner drums to contain the processed liquid, an outer drum surrounding same and providing an annular space for retaining a heating fluid (heated by an electrical heater), a helical coil to carry cooling fluid through the heating fluid, a motorized pump or impeller to agitate the treated liquid to optimize heat transfer, and a control system to switch the heater on and off, actuate ...

A master batch for the production of cross-linked polymer pipes is described. The master batch comprises carbon black and a polymer carrier consisting of a Ziegler-Natta catalyzed polyethylene with a density of at least 0.940 g/cm.sup.3. A cross-linkable polymer composition comprising the master batch and a chromium catalyzed polyethylene base polymer, and a cross-linked polyethylene pipe made by cross-linking the cross-linkable polymer composition are also described.

An improved process and apparatus used to perform the process for batch distillation of a multi-component mixture containing three or more components is provided. The process and apparatus uses at least three distillation zones. For a time period during distillation operation, the component of intermediate volatility is collected along with the collection of either the volatile component and/or the heavy component.

A batch winder includes a non-driven compensating roller or dancer roller placed in a loop of a fabric web, wherein the compensating roller is displaceable transversely of its axis of rotation by means of the force of a spring. When the compensating roller is displaced, the compensating roller influences through an initiator an inductive proximity switch which is coupled through an electrical regulating unit to at least one electric motor which drives at least one of the winding rollers which ex...

A batch type toaster includes a cool remote waiting zone and an intrinsically controlled transport mechanism that retains the bread in said waiting zone while the toasting zone is heating to optimum toasting conditions and subsequently moves the bread into the preheated toasting zone until the desired browning is obtained.

The edges of the upper portion of a stack of sheets are driven horizontally into the high friction periphery of a rotating roll which raises the edge portions from the stack in succession. The rotating roll is then pivoted about an external axis until it is supportingly disposed under the raised batch. A second roll or roller is then lowered onto the batch so that the raised edge portion is confined between it and the lower rotating roll. A nip is thereby formed and the entire batch of sheets is...

A batch mixer for mixing a container of concentrate and diluent, the batch mixer comprises a mixing tank; and a drawer assembly for delivering the concentrate to said mixing tank. The drawer includes a multiple position receiving station for permitting the concentrate to be arranged in a plurality of configurations.

There is disclosed a batch counter for tablets and tablet-like items comprising a hopper with a wide bottom opening for a supply of the items to be counted. A channel member is adapted to channel the items from the hopper to a counter device so as to pass in single file and spaced apart at the counter device so that the counter device can count the passage of individual items from the hopper. The channel member comprises a lightweight, vibratory, V-section guide channel resiliently suspended, do...
