Abstract: An apparatus includes a first member coupled to a second member. The first member defines a chamber containing a dry powder and includes a chamber wall that forms an outer boundary of the chamber. The second member includes a surface covering the chamber and defines an intake channel and an exit channel. The exit channel is fluidically coupled to the chamber via an exit opening. The intake channel is fluidically coupled to the chamber via an intake port. A center line of the intake channel is tangential to a portion of the chamber wall such that a portion of an inlet airflow conveyed into the chamber via the intake channel has a rotational motion. The intake port is defined at least in part by an intake ramp. The intake ramp includes a transition surface that forms an exit angle with respect to the surface of less than 105 degrees.

Abstract: A means of scaling up fluidized bed chemical vapor deposition (FBCVD) production by using two or more small reactors instead of one large reactor. Each reactor has its own process gas delivery and exhaust lines. The furnace heating is designed such that each reactor has its own heater or there may be one large heater designed to keep the group of reactors at a constant temperature. This allows the shut down of a failed reactor without affecting production from other reactors.

Abstract: A process of using a non-radioactive tracer in the monitoring of the flow of a traced fluid is disclosed. The process includes injecting a tracer containing fluid at a first point and analyzing at least one sample from a second point in the flow of the fluid for the tracer compound. In one embodiment heavy oil is traced with a long chain hydrocarbon having a primary chain of more than 25 carbon atoms, the compound preferably being a saturated hydrocarbon. Exemplary tracer compounds include pentacosane (C25H52); hexacosane (C26H54), heptacosane (C27H56), octacosane(C28H58), nonacosane(C29H60), triacontane(C30H62), hentriacontane(C3lH64), dotriacontane(C32H66), tritriacontane (C33H68), tetratriacontane (C34H70) and the like.

Abstract: An enhanced oil recovery process uses an injectant containing water and an additive. The additive is an organic compound having a total of 1 to 10 carbons and at least one functional group containing a heteroatom. The additive is present at a concentration of between about 0.01% and about 20% by weight of the composition. The injectant is injected at a temperature of between about 100° F. to about 500° F. Hot water flooding with the additive provides enhanced oil recovery in medium to heavy oil reservoirs.

Abstract: A system and method is provided for testing a computer system main memory during system startup. An initial block of memory is tested and marked as valid or invalid during a startup sequence, with the remaining system memory initially marked as bad. An operating system and applications can be loaded into the initial block and operate normally, and a concurrent process is invoked to test the remaining system memory. This allows the remaining system memory to be tested and marked as valid during normal system operation.

Abstract: An apparatus and method for heating refrigerant in the chiller of a conventional refrigeration system, whereby refrigerant is removed from the chiller and pumped to a heat exchanger, wherein the refrigerant is heated before being returned to the chiller to cause the pressure of the refrigerant in the system to increase. An electrical control structure monitors and controls the pressure and temperature of the refrigerant within the system.

Abstract: The permeability of an underground formation near a wellbore can be substantially decreased by the injection of one or more slugs of an aqueous solution containing an in situ forming gel of lignosulfonate and a monomer of acrylamide or acrylic acid, initiated by persulfate or hydroxylamine and a relatively small amount of a metal salt having a polyvalent cation. The gel can be formed in the formation by delaying the mixing of all of the gel components into the aqueous solution until just prior to injection or splitting up the components into two aqueous solutions so that they are not mixed until they are in the formation.

Abstract: A method of enhanced oil recovery comprising injecting a surfactant system comprised of an oxidized alkali lignin and an anionic and/or nonionic surfactant into a formation containing oil and producing the oil thus mobilized.

Abstract: A digital computer system including a computation unit (14), a main store (12), a virtual address translator (10), a microinstruction control unit (170) and an instruction code prefetch circuit (212). User instruction codes are stored sequentially in the main store (12) which is accessed for read and write operations by the virtual address translator (10). The instruction code prefetch circuit (212) retrieves the user instruction codes from the main store (12) and holds the instruction codes in a register (16, 18). The instruction codes are transferred from the register (16, 18) to the computation unit (14) in sequential order of use. The microinstruction control unit (170) produces selected microinstructions which are executed by the computation unit (14) to accomplish the operations specified by the user instructions. Designated microinstructions include commands which activate the instruction code prefetch circuit (212) to retrieve the succeeding user instruction codes from the main store (12).

Abstract: A folded paper box is provided which locks in the erected condition and has apertures in the exterior panels through which a label insert sheet is visible and interior panels which cover the apertures and insert sheet when in place.

Abstract: A control system for a computer includes a control store (30) for storing end op, I-1, I-2 and return words. A microinstruction decode and control unit (170) responds to end op words to initialize and personalize computer components to facilitate subsequent execution of a high level instruction. The control unit (170), in conjunction with a next address logic (162), selects the next microinstruction to be executed in response to a high level instruction. The control unit (170) and logic (162) are responsive to I-1 words to personalize the computer and to select a microinstruction to begin E-phase of a high level instruction. In response to I-2 control words, the control unit (170) and logic (162) select an operand fetch routine in the control store (30), and write a first E-phase address into a local store (138). The return word gates the first E-phase address from the local store (138) to select a microinstruction in the control store (3) to being E-phase.

Abstract: A serialization apparatus for a data processing system wherein access restrictions are automatically enforced: (1) in behalf of individual machine instructions in order to maintain object integrity; and (2) at each user's discretion in order to maintain synchronization among all concurrent users of any given object. Various types of restrictions can be enforced in behalf of both machine instructions and users, allowing concurrent access to objects at various levels where appropriate.
