Abstract: A hydraulically supported roller comprises a hollow cylinder that rotates about a stationary cross-head. Cylindrical recesses are radially disposed in the cross-head. Piston-like supporting plungers are displaceable in the recesses against the inner circumference of the cylinder. To limit the stroke of the supporting plunger in the cylinder recess and, hence, the displacement of the cylinder relative to the cross-head, at least one conduit is provided, which leads from the interior of the cylindrical recess to the clearance space outside of the cross-head. Pressure fluid is allowed to escape from the cylindrical recess to limit the stroke when the conduit is uncovered at a predetermined stroke by the supporting plunger.

Abstract: Two cores for circuit boards or cards are simultaneously processed.In particular, two cores are provided wherein each is a dielectric material having conductive planes on both major surfaces thereof. The two cores are temporarily fixed together by sealing the peripheral face planes thereof.The two external conductive planes are then simultaneously processed to thereby form signal patterns.The seal is then removed from the peripheral face planes and the two cores are separated from each other, thereby simultaneously providing the two cores.

Abstract: For the attachment of components using the SMT method a procedure is suggested in which the adhesive used is activated prior to fitting of the components to the circuit board by irradiation with light having a wavelength in the range of 200 to 600 nm to such an extent that the desired initial tackiness is maintained and there is no formation of skin on the surface of the adhesive. This makes it possible to cause the adhesive composition to fully cure in a shorter time and at lower temperature than has been possible so far without the wettability of the adhesive during the fitting of the components to the circuit board being impaired.

Abstract: A method of self packaging an integrated circuit chip on a printed circuit board where conductive leads form an electrical connection with interconnect leads on the printed circuit board. A centering frame placed on the printed circuit board serves to align the leads. A cooling cap which dissipates heat from the integrated circuit chip is placed over the centering frame and integrated circuit chip. In one embodiment, the leads form a pressure fit and the cooling cap forces the pressure-fit electrical connections. In another embodiment, the leads make rubbing contact with each other.

Abstract: An electrical connector having an insulating housing has a rear face with a plurality of electrical terminals extending therethrough. A sealant material in the form of a hotmelt material is placed over the ends of the terminals and the connector, including the sealing material, is thereafter heated to melt the material. The sealing material flows around the terminals and partially into the apertures of the housing to provide for a sealed atmosphere on the interior of the connector housing.

Abstract: The method of making a round-rolled part for a heat exchanger comprises connecting the tubes and the irradiating elements to each other to form a rectilinear network, clamping both ends of the rectilinear network and stretching and bending the clamped network so that it assumes an arcuate shape. The premise adopted is that of a network of flat tubes consisting of rectangular tubes and irradiating elements between them, the tube network being bent round around a narrow side of the tubes. The network has one end rigidly gripped on the bending tool. The tubular network is wound onto it by rotating the latter. There is applied to the other end of the network a retaining force which counteracts the winding-on force and which maintains the tube network under tensile stress. The apparatus comprises a rotatable round bending tool and a clamping means which tangentially clamps the end of the network. Spaced from the round bending tool there is a mating holder for firmly gripping the other end of the network.

Abstract: During solder-reflow attachment of surface-mount electronic components to a printed circuit board, vibrational energy sufficient to overcome the static coefficient of friction between the leads of a component and their respective connector pads is applied to the board, with the result that the surface tension of the molten solder between the leads and the pads will produce a best-fit alignment of the leads of each component on their corresponding connector pads.

Abstract: The subject invention provides a method and assembly (10) for upholstering a foam cushion (16) with fabric (12, 14). A locator strip (10) accurately positions the fabric (12) upon the cushion (16). The locator strip includes an array of U-shaped pockets (30) along one edge which are separated by finger-like projections (32). A thin fracturable filament (40) is fixedly attached to the distal end (34) of the projections (32) to enclose the pockets (30). The locator strip (10) is sewn between the edges (18, 20) of two fabrics (12, 14) with thread (36) stitches passing through the pockets (30) and around the projections (32). The locator strip (10) functions to guide the edges (18, 20) of the two fabric covers (12, 14) into an elongated slot (22) in the cushion (16).

Abstract: A robot having a robot arm swingable from a position outside a car body conveying line to the line and movable in the directions of length, width and height of the car body is provided with a support frame carrying a jig for holding the window glass. The frame is tiltably mounting on the arm via a tilting shaft. A first detector is mounted on the frame for detecting a deviation the car-width direction of the jig with respect to the window portion. A pair of second detectors are provided on the frame at positions which are symmetrical with respect to the car width direction center line of the jig for detecting deviations in the plane of the window opening. First, deviation detected by the first detector is corrected by moving the jig in the car width direction. Then, deviation in tilt detected by the second detectors is corrected by tilting the jig. Finally, deviation in height detected jointly by the second detectors is corrected by raising or lowering the jig.

Abstract: Initially, an uncut gear blank is softened by a heat treatment process to provide a relatively soft level of hardness throughout. Then, the softened gear blank is machined so as to form a plurality of teeth about the circumference thereof. The relatively soft machined gear is next subjected to a prehardening process, wherein the surfaces of the teeth and the outer region of the core are hardened to a predetermined intermediate level of hardness. Finally, the prehardened gear is subjected to a contour hardening process such that the surfaces of the gear teeth are further significantly hardened. The outer region of the core of the gear remains at the intermediate hardness level, while the inner region of the core remains at the relatively soft level.

Abstract: A rifle or handgun bullet having a base and a leading end of ogival shape extending for a portion of its length is divided into a plurality of sections by parting lines extending radially from the central axis and terminating a short distance from the outer wall, whereby the sections are joined by relatively thin webs at their outer edges. The parting lines extend longitudinally from the leading end through at least the ogival portion to as much as 90% of the length of the bullet. Upon impact with a lubricious target the sections separate from one another and from the base, i.e., the portion into which the parting lines do not extend. The bullet is fabricated in a two-stage operation, first forcing a punch longitudinally into a cylindrical slug of malleable metal contained within a die, and then compressing the slug radially inwardly to force essentially all air from the spaces formed by the punch, thereby and forming the ogival leading end.

Abstract: A coil mounting method and apparatus is disclosed, for example, for mounting coils to the inner periphery of a cylindrical core in assembling a cylindrical rotary transformer of a VTR cylinder. A wire is wound round the outer periphery of a coil holding jig that is capable of opening and closing in a radial direction. After the coil is formed, the coil holding jig is inserted into a cylindrical article and opened radially to have the coil fitted in a coil groove formed in the inner periphery of the cylindrical article. The mounting of the coil to the inner periphery of a cylindrical article can be done in a short time through a reduced number of steps.

Abstract: A sprue bushing which eliminates melt leakage and a method of making the same are described. A cylindrical bushing body having a first, preselected uniform diameter has an annular cavity formed therein which axially extends within the bushing body for a predetermined length and which separates the bushing inner core from the bushing body. A heating element in the form of a ceramic insulator sleeve is inserted into the annular cavity and a particulate refractory material is deposited into the annular cavity to fill the remainder of the annular cavity. When filled, the bushing body is swaged down to a second preselected uniform diameter to compact the powdered refractory together with the preformed sleeve to form a solid heating element. A runner passage is then drilled through the inner core so that the inner core is integral with the bushing casing.

Abstract: A method of forming a sealed connection to a coaxial cable, preferably splicing two or more coaxial cables comprises:(a) forming a connection between the central conductor e.g. a solder or crimp connection;(b) positioning and recovering a heat shrinkable sleeve over the connection, the sleeve containing a shield portion for connecting the shield of the coaxial cables and being provided with quantities of sealing material which will extend beyond the ends of the sleeve after recovery; and(c) recovering a further heat shrinkable sleeve over the connection. Further sealing elements are provided with fuse with the sealing material associated with the other sleeve to form a barrier against ingress of moisture to the electrical connection.The method is particularly suited to the formation of connections that will be subjected to large changes in ambient pressure as may be experienced in aircraft.

Abstract: A fixture engages each leg of a chair leg assembly to support each leg against longitudinal displacement along respective leg axes. A ram and associated drive member are mounted opposite each leg free end so that each ram axis is substantially aligned with one leg axis. A glide is adapted to fit loosely on the leg free end in a first position and to be driven tightly onto the leg in a second position. A pair of cam arms are coupled to the ram so that as the ram advances toward a leg that has a glide in the first position thereon, the cam arms and jaw members at the free ends of the cam arms, pivot toward the leg. The jaw members cooperate to align the leg axis with the ram axis while the glide is in the first position and to support the leg transversely to the leg axis as the ram advances to drive the glide into the second position.

Abstract: A synthetic plastic bag for containing liquids, e.g., urine, has a plastic outlet tube. It is manufactured by a first step of seam welding the tube between two superposed bag walls. In a subsequent step, an encircling sleeve is slid over the tube to a position where it contains within it the portions of the bag walls on either side of the tube. Thirdly, this sleeve is compressed onto the tube by a crimping operation conducted with the crimping force applied in a direction substantially parallel to the plane in which the bag walls lie. The tube may be part of a tap or other outlet fitting such as a push-pull tap.

Abstract: The object of the process is to obtain an intermediate short-circuiting ring in a squirrel cage rotor by filling. It makes use of the technique consisting in automatically cutting out and assembling rotor laminations by means of a follow-on machine in which the laminations are cut out from a strip, rotated through a determined angle and provided with half-cutouts for their assembly in a packet. The process consists in eliminating at least one tooth in every two from the laminations whose position in the packet corresponds to the situation of the intermediate short-circuiting ring, and turning these laminations through an angle such that when filling is effected a continuous annular zone of nonmagnetic material is obtained.

Abstract: The assembly comprises a first slide (34) carrying a wire insertion tool (38) and a second slide (80) carrying support tools (92). As the slide (34) descends through a working stroke to cause the wire insertion tool (38) to insert a wire (W) into the wire slot (18) of an electrical terminal (10') of a multicontact electrical connector (2), support noses (96) of the support tools (92) which are in an open position, enter the mouths of the wire slots (18) of the next adjacent terminals. The wire insertion tool (38) continues to descend past the noses (96) to insert the wire (W) into the slot (18) of the terminal (10') and the support tools (92) close so that their noses (96) engage the terminals (10) on either side of the terminal (10') to be loaded with wire, thereby to restrain splaying of that terminal (10') as the wire (W) is inserted into its wire slot (18).
