20050150413, Jul 14, 2005

Filed:

Dec 12, 2003

Appl. No.:

10/733536

Inventors:

Steven Lord - Clinton MA, US

International Classification:

F42B005/16

US Classification:

102436000

Abstract:

This invention describes ammunition cartridges for pistols or other armaments with propellant-filled casings having a generally square, rectangular, rounded oblong or ellipse-like cross-section. These casings would neck down over a short distance at the front to mate with the bullet. These shapes would allow more rounds of equivalent firepower to be contained in a shorter magazine or smaller diameter revolver cylinder than is possible with standard circular cross-section ammunition.

Steven M. Lord - Malden MA

Assignee:

Proconics International, Inc. - Wilmington MA

International Classification:

B65G 6500

US Classification:

414752

Abstract:

Apparatus for inserting a semiconductor wafer in a slot of a holding post including a wafer support member or paddle for supporting the wafer and inserting it into a slot and rotation device for rotating the support member by the angle necessary to cause edges of the wafer to be received at the centers of the slots.

Appl. No.:

7/471703

Inventors:

Richard F. Foulke - Carlisle MA
Steven M. Lord - Malden MA

Assignee:

Proconics International, Inc. - Wilmington MA

International Classification:

B65G 6502

US Classification:

414416

Abstract:

Wafer transfer apparatus including a wafer-pickup element having suction openings closer to the edge of wafer than the wafer's center so that the wafer can be picked up with greater certainty as to the locations of the wafer edges, the openings being surrounded by raised portions so that the region of the wafer-pickup element between the opening is at a lower elevation than the raised portions so as to facilitate picking up warped wafers.

Steven M. Lord - Malden MA

Assignee:

Proconics International, Inc. - Woburn MA

International Classification:

B65G 6500

US Classification:

414416

Abstract:

Wafer transfer apparatus including a wafer-pickup element having suction openings closer to the edge of wafer than the wafer's center so that the wafer can be picked up with greater certainty as to the locations of the wafer edges, the pickup element being thin and made of a structural layer of rigid structural material having grooves and a TEFLON layer laminated to the structural layer and having suction openings, the grooves and covering portions of TEFLON defining vacuum passages.

Appl. No.:

6/381292

Inventors:

Richard F. Foulke - Carlisle MA
Steven M. Lord - Malden MA

Assignee:

Proconics International, Inc. - Woburn MA

International Classification:

B65G 1732

US Classification:

414787

Abstract:

Apparatus for placing a first element at a receptacle location on a second element, there being associated with the precise receptacle location some known variation in the shape of the second element, the apparatus comprising a support member for supporting the first element while the member is translated toward the second element along a placement direction, a first transport device for moving the support member or the second element along a direction transverse to the placement direction, and a sensing device located on the support member for sensing the relative alignment along the transverse direction of the support member and the variation in shape, the sensing device comprising an energy-beam source adapted and positioned to direct an energy beam along a path that interacts with the variation in shape at least when the support member and receptacle location are aligned so that more of the beam is transmitted along the path when the member and receptacle location are aligned than when the member and receptacle are not aligned and an energy beam sensor adapted and positioned to detect the difference in the amount of the beam transmitted along the path.

Appl. No.:

7/463278

Inventors:

Steven F. Lord - Rumford RI

Assignee:

Electron Fusion Devices, Inc. - East Providence RI

International Classification:

B67D 542

US Classification:

222327

Abstract:

A dispenser for viscous fluids includes a tubular cylindrical barrel member, a dispensing nozzle on one end of the barrel member and a piston element which is sealingly received in the barrel member and slidable therein in a direction toward the nozzle for dispensing a viscous fluid from the barrel member. The barrel member and the piston element are constructed so that the piston element is freely slidable in a reverse direction in the barrel member to relieve the pressure on the fluid in the barrel member after a dispensing operation has been completed and to thereby eliminate post extrusion from the dispenser. The dispenser is operative in combination with a dispenser gun which includes a drive plunger and an advancing mechanism which is operative for advancing the drive plunger in order to advance the piston element of the dispenser in the barrel member thereof. The advancing mechanism is further operative for automatically retracting the drive plunger after a dispensing operation has been completed so that the piston element is free to move rearwardly in the barrel member to relieve the pressure on the fluid in the barrel member.
