Method of forming leads for attachment to semi-conductor devices

Abstract: A METHOD OF ATTACHING LEADS TO A SEMI-CONDUCTOR DEVICE INCLUDES THE STEPS OF INLAYING A CONTACTING METAL COMPATIBLE WITH A SEMI-CONDUCTOR ELEMENT ALONG A METAL STRIP, UPSETTING THE METAL STRIP AT SPACED PORTIONS THEREALONG SO AS TO PROVIDE A DEPRESSION ON ONE SIDE AND AN UPSTANDING PORTION ON THE OPPOSITE SIDE OF THE METAL STRIP, REMOVING THE UPSTANDING PORTION SO THAT THE INLAY AND STRIP IS SUBSTANTIALLY REDUCED IN THICKNESS AT SAID SPACED PORTIONS, AND THEN STAMPING THE STRIP AT SAID SPACED PORTIONS TO DEFINE THE INTEGRAL CANTILEVER LEADS HAVING THE CONTACTING METAL ON THEIR EXPOSED ENDS.

Stencilled stamping device having fluid flow valve control

Abstract: A stamping device comprising a body having a web provided with a valve opening therethrough. A valve member is disposed in the opening and engages the web for closing the opening. A housing is secured to the body and forms an extension of the web. A stencil is disposed over a fluid reservoir pad in the housing.

Rotational die stamping tool

Abstract: The present die stamping tool has a baseplate shaped to conform to the surface of a rotational body, such as a cylinder. Working blades are held in grooves or slots of the baseplate by means of serrated back edges which may be provided with gripping teeth. The rotational die stamping tool is made by shaping or bending the baseplate, cutting said grooves or slots, serrating the back edges of said working blades and anchoring said serrated back edges in the grooves or slots.

Foam-covered coil and methods of manufacturing the same

Abstract: The present invention relates to methods, particularly suited for the coil-coating industry, for continuously covering and permanently bonding a heat stable plastic foam to a metal web traveling at comparatively high speeds of up to 300 feet per minute through coil-baking ovens having ambient atmospheres above 400* F. The metal web may be an unwound coil of steel or aluminum, and the foam may be expanded polyvinyl chloride. The foam-covered metal coil product of the invention, which may include a plastic film laminated thereto, is suited for postforming by stamping, bending, crimping, roll forming, or the like.

Stamping process for metal objects

Abstract: In a process for producing metallic objects by stamping blanks located side-by-side in echelon formation in a metal strip which is then advanced through shaping means for executing shaping operations there is provided blanks to be stamped by cutting said strip along portions of the true peripheries of the objects so that said blanks remain connected to spacer web portions of said strip solely by connecting elements maintaining said blanks within said strip during the subsequent shaping operations and until final separation of the finished objects.

Apparatus for marking textile article

Abstract: An apparatus for marking textile articles having a carrier movable between two limiting positions, a roll of label tape and feeding means on the carrier, a stamping device operatively associated with the end of the tape while the carrier is in one of the two limiting positions, and a cutter for the tape and means for applying the marked and cutoff piece of tape to the article while the carrier is in the other of the two limiting positions.

Decorative light holders

Abstract: A holder for Christmas light sockets is made from a pressing or stamping thus providing four upstanding legs which embrace the light socket. A band surrounds the upper ends of these legs and holds the socket firmly in position and the two remaining legs of the stamping can be utilized to engage the wire feeding the sockets or can have a wrap around device substituted therefor which engages the branch of a tree or the like.

Machines for stamping pasty materials into cakes, bars or tablets

Abstract: A device for use in a machine for stamping pasty materials into cakes, bars or tablets of the type wherein the soap tablets are formed by pairs of mold halves meeting by passing through the openings of a jerkily rotating box, wherein said box is in the form of a disc provided with through openings, adjacent which projections or lugs are located and adapted to hold both the soap blocks to be moulded and also the excess of soap paste exiting from the periphery of the coupled mold halves, in the disc adjacent said lugs there being prearranged at least two through holes intended to be passed through by a pushing member moving the excess of soap paste from the disc to which it was attached.

Bed and platen printer with ribbon inkers

Abstract: A stamping apparatus is provided for use in forming a composite multicolored indicia on a workpiece. The apparatus utilizes a single die in combination with a plurality of transfer ribbons of different colors and a rotatably mounted workpiece-supporting member whereby a plurality of multicolor impressions can be simultaneously made on the supported workpieces.

Improvements in or relating to methods of isostatic pressing

Abstract: 1,121,888. Stamping. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 6 March, 1967 [30 March, 1966], No. 14108/66. Heading B3Q. [Also in Division B5] Objects of sheet metal are shaped by placing the sheet against the shaped wall of a mould, the wall being inflexible but having insufficient strength to withstand the full fluid pressure across it, evacuating air from the space between the sheet and the mould and immersing the assembly in a fluid under high pressure which presses the sheet against the wall and also supports the mould wall. As shown the metal 9 1 is in the form of a cup and is clamped against the shaped mould 10 1 by clamp 13 1 , sealing being accomplished by O-ring 12 1 . Air is evacuated from the space between the sheet 9 1 and the mould 10 1 through tube 16 1 , the valve 17 1 is then closed and the assembly immersed in a bath of fluid under pressure. The shaped object can be removed from the mould after pressing as it tends to separate slightly from the mould sides as the pressure is released. The sheet metal may also take the form of a frustum of a hollow cone clamped at both ends or may be covered on the side away from the mould face by a flexible membrane.

Stamping metal articles from sheet

Abstract: A piece of sheet metal is put on a die, the rims being held down by a holder, and a punch is lowered onto the piece to commence the forming of a cylindrical section. Then the product is finally shaped by the pressure of a fluid which is fed into the gap between the punch and the sheet metal until it takes on a domed shape, during which action the edges of the piece of metal are diplaced towards the centre.

Strip stock handling equipment

Abstract: Equipment for uncoiling and conditioning strip stock to be utilized in devices such as punch presses, shears, and stamping machines.

Improvements in or relating to method of manufacturing electrical circuit modules

Abstract: 1,118,998 Making electric circuit modules MEL EQUIPMENT CO Ltd 2 May, 1967 [3 May, 1966], No 19432/66 Heading B3A [Also in Division H1] An electric circuit module is made by stamping a metal blank and securing electrical components 9, 10 in the stamped out portions The blank may be cut from a strip of " Monel " (Registered Trade Mark), brass or nickel silver either before or after stamping Reference marks 2 are made along each side of the blank which are sensed by a component supplying and positioning machine Notches 5 are provided in the cross-strips 7, 8 to permit easy removal from the end strip 4 and notches (5 1 ), Fig 1 (not shown), to accommodate the components The assembly is preferably encapsulated in epoxy resin with limb portions 11 acting as terminals The components may be resistances 9 and a transistor 10 arranged to form a NOR gate The electrical components secured in the blank may alternatively be secured in a box-like structure or held between two spaced surfaces instead of being moulded in epoxy resin

A device for cutting apertures in the wall of a plastic tube

Abstract: A device for stamping apertures in the wall of a corrugated thermoplastic tube comprises a rotatable hollow nut for guiding the outer wall of the tube, and bits for stamping apertures in the tube without supporting the inner wall of the tube during stamping from outside. The bits are depressed in the plastic material by operating cams or by a guiding groove. Preferably the bits are effective in the area just besides the profiled end of the nut.
