Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

B05D 304
B05D 142

US Classification:

427 96

Abstract:

International Classification:

B23Q 700

US Classification:

29559

Abstract:

Panels are positioned relative to a pattern by moving the pattern onto a registration mechanism having contact elements, engaging contact areas on the pattern with contact elements by moving the contact elements synchronously and equidistantly while allowing the registration mechanism to move as the elements engage the contact areas, locking the position of the registration mechanism, and engaging contact areas on sequential panels by moving the contact elements of the locked registration mechanism synchronously and equidistantly to contact areas on one panel after the other.

International Classification:

B23Q 700

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

B23K 302
H05B 300

US Classification:

219233

Abstract:

An electrically heated soldering device adapted to simultaneously heat a plurality of spaced electrical elements in a reflow soldering operation includes an elongated metal laminate of substantially U-shaped cross section having a bight portion between two side portions which may be parallel or divergent. The laminate includes a layer of aluminum between a layer of copper and a layer of stainless steel, with the layers being roll bonded together. The copper and aluminum layers are removed at the bight portion to expose the stainless steel layer and form a heat generating zone for contacting the plurality spaced electrical elements which is corrosion resistant and nonwettable by solder. The edges of the copper and aluminum layers adjacent to the exposed stainless steel bight portion are shaped to impart a selectable temperature profile, either uniform or non-uniform along the length of the bight portion. The exposed surface of the stainless steel portion can be provided with a ceramic coating to electrically insulate bight portion from the elements to be soldered.

International Classification:

G01B 1126

US Classification:

364559

Abstract:

A metrology system to analyze panel misregistration in a panel manufacturing process includes a software controlled system which checks defined panel parameters on the four corners of a panel and related artwork for processing with a master pattern etched on a glass reference with a machine vision measuring system. The panel or artwork being checked is positioned by panel center registration means to align the center of the panel with the center of the master pattern. Displacement and rotational differences are entered under software control into a data base and analyzed by a stored program intelligent analyses system into a plurality of parameters based on a parameter model which permits an analysis of the cause of the misregistration.

Appl. No.:

Hans H. Ammann - Chester NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

F27B 1400
F28D 1500

US Classification:

432 13

Abstract:

A process and apparatus are disclosed for controlling losses in volatile working fluid systems. In accordance with the process, the object upon which a work operation is to be effected is sequentially moved from a first sealable chamber to a second such chamber and back to the first chamber. While in the second chamber the object is exposed to a working fluid vapor which elevates the temperature of the object to a level near the boiling point of the working fluid. Thereafter, while still in the second chamber, a substantial portion of the working fluid is drained from the object such that the sensible heat acquired by the object upon its elevation of temperature is sufficient to evaporate working fluid remaining on the object upon its removal to the first chamber. Upon removal of the object to the first chamber the object is thoroughly dried through control of the partial pressure of the working fluid vapor contained within the first chamber atmosphere. This control is effected by a closed devaporization loop coupled to the first chamber.

Inventors:

Hans H. Ammann - Chester NJ

Assignee:

AT&T Bell Laboratories - Murray Hill NJ

International Classification:

B23Q 700

US Classification:

29559

Abstract:

A method and apparatus for positioning a locating mechanism and the artwork frame of a panel processing machine has been devised utilizing a flexible beam apparatus for suspending the panel location mechanism and artwork frame which permit these devices to be moved out of the way during loading and unloading panels into and from the work surface of processing machinery. The flexible beam suspending the location mechanism in the disclosed embodiment comprises two parallel surface thin members of resilient sheet material. These members are each attached along one edge to a rigid portion of the machinery and along an opposing edge to the panel locating mechanism. This flexible beam arrangement permits the locating elements of the locating mechanism to be moved from and restored to a previous position with great accuracy. A pair of co-planar high aspect ratio sheet beam members are used to support the artwork frame. One end of these flexible beams is each attached to the machine and an opposing end is attached to the artwork frame.
