C12Q 1085

US Classification:

435 29

Abstract:

The movement of an air mass is monitored by releasing a tracer entity at a iven location, collecting a sample of air at a different location and analyzing the collected sample of air for the presence of the tracer entity by using Bacillus thurengiensis as the tracer entity and by analyzing for the presence of the bacterium by effecting a culture in a medium capable of supporting bacterial growth and preferably containing citrate as the sole source of assimilable carbon.

G01N 2572

US Classification:

374 45, 374124, 374 5

Abstract:

Chemical agent warfare materials and their simulant liquids are identified on terrestrial surfaces at a distance by recognizing the contaminants infrared fingerprint spectrum brought out in thermal luminescence (TL). Suspect surfaces are irradiated with microwave light that is absorbed into the surface and, subsequently, TL is released by the surface. An optics receiver collects the released TL radiant light, and a data acquisition system searches this TL radiant flux for the contaminants fingerprint infrared spectrum. A decision on the presence or absence of any-of-N contaminants is done by a neural network system that acts as a filter through real-time pattern recognition of the contaminants unique infrared absorption or emission spectra.

Appl. No.:

7/551108

Inventors:

John P. Fiala - Forest Hill MD
Irving F. Barditch - Baltimore MD

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F41A 1969

US Classification:

102293

Abstract:

The present invention relates to an apparatus and method for clearing the uling black powder residues deposited on the electrical connectors of electrically detonated munitions. A female connector is provided with a recurved lanced outer spring clip which automatically scrapes off the residue on an insulator and contact surfaces of a male bipolar connector plug when the two connectors are rotated with respect to each other.

International Classification:

C06D 300

US Classification:

102334

Abstract:

A control system is provided for igniting and dispensing a smoke pot for ense of a hulled vehicle. The system utilizes a command circuit located inside the vehicle for using the vehicles power source to select smoke pot operations. A user can select an operation to ignite a desired smoke pot or an operation to ignite and release the smoke pot. Two power lines are arranged from the command circuit inside the vehicle to a control circuit located at the exterior of the hull for operating the smoke pot control system. A minimum number of apertures are required in leading the power lines to the control circuit. The control circuit activates the selected operations of the smoke pots.

International Classification:

F23Q 702
F41C 1102

US Classification:

102217

Abstract:

An electrical system which serves to control the firing of multiple grenade aunchers. The system generates multiple coded tone pairs for up to sixteen launchers which are provided to the launchers through a +28VDC line connected to the vehicular power supply. The tone pairs are decoded enroute to each launcher which exercise a firing circuit triggering the grenade launcher's firing squib causing the grenade to launch.

International Classification:

C12M 134

US Classification:

4352913

Abstract:

Apparatus for growing cultures of microorganisms comprised of an inert ri porous member having passageways extending therethrough and structure for bringing liquid in contact with one side of the member. In one species of the invention, the passageways are small enough to prevent microorganisms from flowing through them.

Appl. No.:

6/518168

Inventors:

Irving F. Barditch - Baltimore MD

International Classification:

G11C 1134

US Classification:

365114

Abstract:

A large scale integrated circuit device such as a random access memory or a read only memory has its top cover removed and information is read into the device in the form of radiation which is selectively applied to the exposed surface of the device. The radiation is of suitable frequency and intensity as to be capable of placing any of the individual devices within the array to a given logic state. The entire device is electrically read out in the normal fashion. The radiation may be modulated in any desired manner and can, for example, be modulated by a transparency containing the desired input information. Gray shades are obtained by employing a plurality of large scale integrated devices which are identical to one another and which receive the same radiation distribution with a different attenuation for each of the devices. The electrical readout process can then compare the state of respective identical devices within each array to determine gray shades.
