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.

The punch includes an axially extending piercing end which pierces a small opening in the cone-shaped panel portion and an arcuate drawing portion which is driven against and through the panel opening, enlarging the panel opening. The annular riveting portion of the female element is then driven into the cone-shaped panel portion and through the panel opening, drawing the panel portion into a tubular shape engaging the external surface of the riveting portion. Finally, the riveting portion is driven against a center post of the die member, radially outwardly deforming the free end of the riveting portion and forming a mechanical interlock with the tubular panel portion.

Abstract: A component placement machine comprising an X-Y table, at least two pick-up tools movable between an up-position and a down position is set up to allow for movement of each tool in a horizontal plane in moving between its down position and its up position. A test piece is removably mounted in a pocket on the X-Y table so that it is accurately reproducibly mounted. The test piece is picked-up by a pick-up tool in its down position and a detection device detects the actual position of the piece on the tool in its up position. This is repeated for all the tools so that, when the X-Y table drive is used to compensate for variations in component position on a tool, as detected by the detection device, account can be taken of said movement in a horizontal plane.

Abstract: A method of making a repairable transformer having an amorphous metal core 1 wherein three uncut legs of an annealed wound amorphous metal core are covered with an adhesive impregnated material 10 while leaving the cut leg, 6 and 7, and both adjoining radii uncovered. The adhesive is cured, causing the adhesive to bond to the core. The core joint is opened and coils 11 and 12 are placed over the legs that adjoin the cut leg.

Abstract: The invention is directed to a cutterhead for attachment to a vegetation cutting apparatus. The cutterhead has a housing with a spool on which a coil of cutting filament is wound. The cutting filament is paid out in incremental lengths when its ends effective for cutting are worn. This is achieved with an incremental rotation of the spool while the cutterhead rotates. For this purpose, the filament coil must have a winding rotation corresponding to the direction of rotation of the cutterhead. So that the cutterhead can be utilized for oppositely directed rotations as desired, the spool can be turned over through 180.degree. and can be blocked and released in both positions by means of a switching member to provide the incremental rotation. The spool can be seated on the switching member and its position, when installed, is determined by means of a marking which is applied to the adapter nut and to the spool. The adapter nut serves to tighten the cutterhead onto the vegetation cutting apparatus.

Abstract: The present invention discloses apparatus and method for centering the steering wheel of a vehicle prior to alignment of the vehicle wheels using a wheel aligner. A portion of the apparatus is mounted to the vehicle steering wheel for sensing deviation in the position of the steering wheel from a centered position. This portion of the apparatus can be mounted on vehicle steering wheels having different configurations and can wirelessly transmit signals corresponding to the deviations. The apparatus can be used with differently configured steering wheels by virtue of a linked cam assembly in which rotation of either of a pair of cams causes rotation of the other cam in an opposite direction of equal magnitude. In operation, the deviation in the position of the steering wheel from a centered position with a pre-selected tolerance is determined. When the deviation is greater than the pre-selected tolerance, alignment of the vehicle wheels by the wheel aligner is prevented.
