Filed:

Jun 30, 1994

Appl. No.:

8/269421

Inventors:

H. Ernest Schnepf - San Diego CA
John B. Randall - Racine WI
Jewel M. Payne - Davis CA

Assignee:

Mycogen Corporation - San Diego CA

International Classification:

A01N 6304
C12N 120

US Classification:

424 93462

Abstract:

The subject invention concerns novel materials and methods for the control of cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. According to the subject invention, activated toxins of Bacillus thuringiensis var. israelensis (B. t. i. ) are used to control cockroaches. In one embodiment, the subject invention also concerns the use of B. t. PS123D1 to control cockroaches. A truncated form of a toxin obtained from PS123D1 having particular activity to cockroaches is also claimed for use in controlling the pest.

Assignee:

FlowClean Equipment, Inc. - Rocky Hill NJ

International Classification:

B67D 508

US Classification:

222 1

Abstract:

A fluid dispensing apparatus having no moving parts in contact with the fluid includes a fluid chamber and a measuring cup having an open top disposed in the fluid chamber. The fluid chamber is connected to a fluid source which supplies fluid to fill the chamber to a pre-determined level above the top of the measuring cup. As the fluid chamber is being filled, the fluid overflows and fills the measuring cup. A first sensor indicates when the fluid reaches the pre-determined level above the top of the measuring cup and stops the flow of fluid into the fluid chamber. A drain, which is responsive to the first sensor, drains fluid from the fluid chamber until the fluid level drops to a predetermined level below the top of the measuring cup. As the fluid level in the fluid chamber recedes, a pre-determined volume of fluid is captured in the measuring cup. A second sensor indicates when the fluid level drops to the pre-determined level below the top of the measuring cup and stops the flow of fluid from the fluid chamber.

International Classification:

A01N 6300
C07K 1504
C12N 120

US Classification:

4352525

Abstract:

The subject invention concerns novel microbes and genes encoding novel toxin proteins with activity against insect pests of the order Hymenoptera. Pests in the order Hymenoptera are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B. t. PS211B2. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.

Appl. No.:

8/225803

Inventors:

Denis E. Keyes - Rocky Hill NJ
John R. Randall - Freehold NJ
James V. Curcio - South Plainfield NJ

International Classification:

B67D 508

US Classification:

222 64

Abstract:

A fluid dispensing apparatus includes a fluid chamber and a fill tube which forms a closed loop with the fluid chamber. A pair of level sensors are disposed adjacent to the fill tube. Fluid is directed from the fluid chamber into the fill tube through a fill valve. When the fluid level in the fill tube rises to a first predetermined level, the fill valve is closed and a discharge valve is opened to dispense the contents of the fill tube into a container. When the level of the fluid in the fill tube drops to a second predetermined level, the discharge valve is closed and the cycle is repeated.

James V. Curcio - South Plainfield NJ

International Classification:

B67D 508

US Classification:

222 64

Abstract:

A fluid dispensing apparatus includes a fluid reservoir comprising a flexible bag-like enclosure. The fluid reservoir includes a discharge valve connected to a fluid output for dispensing fluid from said fluid reservoir. An electronic controller selectively opens and closes the discharge valve to dispense a predetermined volume of fluid from said fluid reservoir. The fluid reservoir is flexible so that it expands and contracts to maintain the internal pressure of the fluid reservoir constant. In an alternate embodiment, the fluid reservoir has a rigid wall and is provided with an external bladder which expands and contracts to maintain the internal pressure of the fluid reservoir constant. The fluid dispensing apparatus can be configured either as a volumetric filler or as a time pressure filler.
