Filed:

Oct 12, 1999

Appl. No.:

09/415745

Inventors:

Frederick J. Holmes - Plainville MA 02762

International Classification:

G01R 3102

US Classification:

324760, 324537, 324754, 324758, 361748, 29280

Abstract:

An interface circuit board ( ) for high test point density electronic testing equipment has a first thickness signal portion ( ) in which all the signal traces ( ) are routed and a second, thicker integrally formed transfer portion ( ) which transfers the signal traces to a respective test pad ( ) on the lower surface of the transfer portion. The transfer portion is made thicker to strengthen the board and is made integral with the first signal portion to eliminate the need for intermediate solder joints.

International Classification:

F41C 27/00

US Classification:

42 90

Abstract:

A magazine mounting platform having at least one mounting fixture for insertion into the magazine compartment of a firearm thus securing the firearm in place. The magazine mounting fixture may include at least one dowel pin operable for insertion into receivers on the platform. Some embodiments may also include a rotational adapter which allows for a firearm mounted on the fixture to be rotated. Risers may be included to provide additional support for a firearm by securing in place a barrel or a stock. Some embodiments may include magazine mounts for M4 carbine type, AR rifle type or Model 1911 pistol type firearms.

Appl. No.:

8/877032

Inventors:

Frederick J. Holmes - Plainville MA

Assignee:

Semco Machine Corporation - Wrentham MA

International Classification:

G01R 3122

US Classification:

324754

Abstract:

A mounting device (10) is shown particularly adapted for adjustably mounting vectorless test heads for circuit board components and the like to be tested for processing faults of component pin connections with traces of a circuit board in which the components are mounted. A U-shaped bracket (18) is lockably received on a rail (2) and has first and second projections (18d,18e) slidably received through a respective slot (16c,16d) of a leg (16) of a T-shaped member (12). The base leg (14) of the T-shaped member (12) is connected to one end of a pin member (24) which slides through a bore (18p) in one arm (18b) of U-shaped bracket (18) and is threadingly received in a threaded bore (18n) of the other arm (18a) of the U-shaped bracket (18). Rotational movement of the pin member (24) causes T-shaped member (12) to move in a Z direction to permit precise locating of a test head (30) mounted on the base leg (14). The mounting device (10) is also shown mounted on a resinous mounting plate (40) having a plurality of sets (40a) of mounting apertures.
