International Classification:

H05B003/00

US Classification:

219/243000, 219/552000

Abstract:

A heating element of a thermal bonding system has a body and an insert which includes the working surface of the heating element. The body is formed from a thermally and electrically conductive material and the insert is formed from a thermally conductive, but electrically insulative material. A channel runs along the exterior side of the body in alignment with the longitudinal axis of the body and the insert is press fitted into the channel to maintain a fixed interference fit between the insert and body. A heat transfer interface may also be provided between the insert and body to facilitate heat transfer therebetween.

Thomas W. Todd - San Diego CA

International Classification:

B23K 700

US Classification:

148 9R

Abstract:

In a cutting system, a cutting system receptacle device and method of using it for receiving a cutting jet emerging from a work piece being cut, as well as receiving and retaining waste materials or debris. A cutting system receptacle device includes a generally hollow opened-top container, partially filled with a fluid such as water, for receiving and absorbing, at least partially, the heat and energy of the impinging waste materials. A diverter on the inside bottom wall of the receptacle, separates the flow of excess material into two substantially symmetrical, side-by-side, interior chambers of the receptacle. A plurality of deflectors, direct upwardly flowing streams within the receptacle, back downwardly therewithin, for causing them to be retained therewithin. A stand pipe maintains the level of the fluid inside the receptacle device at a predetermined optimal height for a given cutting operation.

Appl. No.:

7/112951

Inventors:

Thomas W. Todd - San Diego CA

International Classification:

B25B 1100

US Classification:

269 22

Abstract:

A clamp device for retaining a side marginal edge of a work piece during a cutting operation, which includes an elongated frame standing along substantially the entire side marginal edge of the work piece, for receiving it during the cutting operation. The clamp device also includes an adjustable upper gripping element which is retained releasably within the frame, and which extends along substantially the entire length thereof, for engaging frictionally the back side of the side marginal edge of the work piece. A lower gripping element is disposed inside the frame, and extends along substantially the entire length thereof, for engaging frictionally the underside of the marginal edge of the work piece. The upper gripping element includes an inflatable bladder for engaging the frame, and an elongated rail, which depends integrally from the bladder, for engaging frictionally the side marginal edge of the work piece, and for pressing it downwardly against the lower gripping element. The method of using the clamp device comprises placing the lower gripping element inside the frame, inserting the work piece inside the frame, between the upper and lower gripping elements, and inflating the bladder to cause the rail to move downwardly into frictional engagement with the work piece, and to press it against the lower gripping element.

Thomas Todd - San Diego CA
Todd B. Skinner - San Diego CA

Assignee:

Toddco General, Inc. - San Diego CA

International Classification:

B23K 303

US Classification:

219 8516

Abstract:

A robotic controlled soldering apparatus is more precise in operation apparatus, and includes a protuberance and complementary shaped socket for defining a universal joint to provide a gimballing action to help prevent unwanted shift in the robotic control unit. A supply of fluid under pressure is directed between the pertuberance and the socket to reduce friction between their respective surfaces to reduce reaction on the delicate robotic arm as the head settles in place.

US Classification:

2281802

Abstract:

A fluxless reflow soldering processing and system having a reactive inert gas control arrangement coupled to a conventional reflow soldering head for enabling solder to wet metallic surfaces for joining purposes. The gas control arrangement includes a set of gas regulating valves and heat exchange units for supplying selected quantities of inert gases under pressure at various temperatures to a soldering area during the soldering process. The inert gases are employed to clean the soldering area of metal oxides and are used to facilitate the forming of a reliable solder joint by inhibiting the formation of metal oxides and by helping to cool down the solder joint in a substantially uniform manner.

Abstract:

A deboning system is adapted for use in separating intact the proximal and distal bones of a fowl wing and for removing the proximal bones substantially intact from the proximal portion to provide a comestible receiving cavity therewithin. The system includes a force applying disjointing unit for separating the proximal and distal bones at their connecting joint, and a deboning unit for removing the separated proximal bones from the fowl wing substantially intact to create the cavity in the deboned fowl wing.

Abstract:

A tool changing system having high current surface mount tools, such as a hot bar reflow soldering head. The tool changing system includes a mounting fixture for connecting and disconnecting the surface mounting tool to a robotic unit. A low profile, small diameter robotic tool adaptor is utilized for coupling a variety of different types and kinds of robotic units to the surface mount tool and to reduce lead to pad misalignment problem caused by non-copolanarity between the mounting surface of the robotic unit and the working surface of the surface mount tool.

International Classification:

H05B 102

US Classification:

219483

Abstract:

An apparatus which provides selectively either constant power, constant current or constant voltage to the heating elements of the thermods. The soldering system power supply apparatus includes devices for monitoring and controlling individual temperature profiles of each soldering thermod heating element. A computerized arrangement controls the power to each thermod in a very accurate manner. For the purpose of adjusting the power to each thermod element as a function of its temperature and the desired temperature profile, a set of temperature sensors are coupled to each of the thermod elements for measuring its temperature. Similarly, a set of energy sensors are also coupled to each of the thermod elements for detecting the amount of electrical energy supplied to each thermod.
