Patent number: 4720998Abstract: A crude oil sampling system that obtains and stores a representative sample of crude oil as the oil flows from a stock tank into a sales line. As crude oil flows from the storage tank during a finite period of time, a much smaller flow is diverted to a closed sample vessel. Accordingly, small sequential samples of the crude flowing from the stock tank is removed so that a true sample is protected within the closed vessel. Hence, the crude contained downstream of the stock tank changes in composition over a period of time while the crude contained within the sample vessel remains unchanged. When it is desired to evaluate the quality of the sample contained within the closed vessel, a circulation pump is energized and the contents of the sample vessel is thoroughly mixed. A hydrometer, including a thermometer associated therewith, is placed within a special gravity sample chamber which heretofore has been isolated from the sample vessel.Type: GrantFiled: June 13, 1986Date of Patent: January 26, 1988Inventor: James D.

The apparatus includes a pump means, a static mixing means and a mixing chamber means. A first circulation means connects the pump means to the mixing chamber means. A second circulation means connects the pump means to the static mixing means and further connects the static mixing means the mixing chamber means. A third circulation means connects the static mixing means to the mixing chamber means. Additionally, a flow control means selectively circulates a combined stream of the water and the polymer alternatively through the first circulation means, the second circulation means or the third circulation means. The method of using this apparatus is also disclosed.Type: GrantFiled: October 18, 1985Date of Patent: May 12, 1987Assignee: Betz Laboratories, Inc.Inventors: James C. Rodgers, John R. Schieber

Patent number: 4650339Abstract: There is described a method of preparing working strength solution in a processing apparatus which comprises adding a requisite volume of concentrated solution to a storage vessel until the liquid level on the storage vessel reaches the top of a standpipe in the storage vessel and continuing to add diluent to the storage vessel so that excess liquid in the storage vessel flows down the standpipe to a connected working vessel, stopping the flow of diluent when the volume of liquid in the working vessel reaches a predetermined volume, then commencing to pump liquid drawn in part at least from the bottom of the working vessel into the storage vessel, the excess liquid in the storage vessel flowing into the working vessel, and continuing to pump liquid from the working vessel to the storage vessel until the specific gravities of the liquid in the storage vessel and in the working vessel are the same.Type: GrantFiled: February 14, 1986Date of Patent: March 17, 1987Assignee: Ciba-Geigy AGInventors: Raphael J. F. Chetcuti, John E. Melbourne

Patent number: 4605310Abstract: A size application system and method utilize a plurality of size boxes associated with one or more slashers. A number of size formulation components are mixed and heated at atmospheric pressure to produce a size formulation having a predetermined composition and temperature. The size formulation is pumped in a closed loop past each of the size boxes. The size level in each size box is sensed utilizing a radio transmitter level control in each size box, which utilizes radio waves to sense the level of size in the box. In response to the sensing of the size level by the radio transmitter level control, size formulation is withdrawn from the closed loop through controlled valves, and supplied to each size box having an amount of size therein below a predetermined desired level.Type: GrantFiled: February 8, 1985Date of Patent: August 12, 1986Assignee: Burlington Industries, Inc.Inventors: Frederick D. Pritchard, John E. Pittard

Patent number: 4605172Abstract: A sensory apparatus for substances containing granular particles which are to be moved or mixed in a casing includes a sensor which is supported on a wall of the casing and protrudes from the wall into the area of the moving substances. The sensor has a deflectable plate by which the sensor is connected to the surface of the wall and has on its outer side at least one measurement receiver providing signals indicating the mixing conditions.Type: GrantFiled: October 1, 1984Date of Patent: August 12, 1986Assignee: Dierks & Sohne GmbH & Co. KGInventor: Dieter Ahlert

Patent number: 4576089Abstract: An automatic roux maker including a pot for heating and agitating (mixing and moving) the roux during the cooking process, in which a motor-driven agitator is included and suspended within the pot for mixing the roux during cooking and for preventing scorching of the roux. At the bottom of the centrally located agitator shaft is included, for example, two diametrically opposed, paddle arms which ride and sweep on the bottom of the pot and are pivotally connected to a slotted support which is capable of floating up-and-down with respect to the agitator shaft. The flexible sweeping of the bottom of the pot prevents any of the roux from remaining on the bottom of the pot for any significant period of time, preventing scorching of the roux.Type: GrantFiled: November 1, 1984Date of Patent: March 18, 1986Inventor: John A. Chauvin

Patent number: 4571092Abstract: A liquid mixing system is disclosed which provides a continuous and constant pressure flow rate during operation, having particular use in spray dampening operations for offset printing procedures. The mixing system includes a stacked arrangement of a batch mixer and feed tank fluidly communicating therebetween, and transfer means sequentially activated to transfer the liquids to the feed tank upon completion of mixing the liquids. The feed tank having means for discharging liquids therefrom at a constant flow and pressure. Control means sequentially operate the system for the admission and mixing of liquids in predetermined amounts to the batch mixer, for transferring the mixed liquids from the mixer to the feed tank, and for discharging the mixed liquids from the feed tank. The system is capable of repetitive mixing and transfer cycles while continuously discharging from the feed tank at a constant flow rate.Type: GrantFiled: September 6, 1984Date of Patent: February 18, 1986Assignee: Ryco Graphic Manufacturing, Inc.Inventor: Thomas G. Switall

Patent number: 4537512Abstract: An apparatus and method for carrying out the Korsakovian dilution of a master tincture contained in a bottle. The bottle is drained through a vacuum pump acting by way of a control water trap. Then the feed station sends a dose of distilled water into the bottle while the agitator processes the mixture. With each new cycle a programmed display is provided.Type: GrantFiled: September 14, 1983Date of Patent: August 27, 1985Assignee: Laboratoires BoironInventors: Jean Boiron, Christian Boiron, Jacky Abecassis, Andre-Marcel Favier
