Abstract: Joining thin heat exchanger tubes to manifold header tanks is improved by extruding thick tubes having channels or microchannels. Tube material is removed from spaced areas of central portions, leaving finned thin heat exchanger central portions and thicker header portions. The tubes are curved, twisted and tilted. The tubes are aligned horizontally, vertically or angularly, and the header portions are welded together. Tube material is removed from the ends of the header portions to form end faces with projections extending from the end faces and surrounding the channels or microchannels. End plates with openings to receive the projections are attached and sealed to the projections and end faces by welding or brazing. The face plates are attached and sealed to openings in the header tanks by welding or brazing. Tube ends are flattened. Rings are added. Ends and rings are friction welded, avoiding areas around channel openings, and polished.

IPC: H04L12/56
Filed: 2000-02-14
Abstract: A data packet transmission method in a packet-switched telecommunication system. A telecommunication protocol comprises a convergence protocol layer for adapting user data packets to convergence protocol packets and a link layer for transmitting the convergence protocol packets as data units and for acknowledging the transmission. A data packet number is defined for the convergence protocol packets to be transmitted. The convergence protocol packets are transferred to the link layer to be transmitted. A data packet number is defined for the received convergence protocol packets and the received convergence protocol packets are acknowledged to the transmitter. The identification data of any convergence protocol packets lost on the link layer are transmitted to the recipient. The counter value of the recipient is updated to correspond to the counter value of the transmitter, to take into account the lost convergence protocol packets.

Abstract: 1,050,934. Making crowned pulley rims. DODGE MANUFACTURING CORPORATION. Jan. 8, 1965 [Feb. 10, 1964], No. 1017/65. Heading B3A. A one-piece rim for a crowned pulley is made from a blank 30 having its ends shaped, as at 32, 34, 36, 38, to correspond to the crown required by bending the blank to U-shape and forming the U blank in a two-part die 50, 52, Fig. 5 (not shown), having a cavity shaped to the crown required, i.e. for the blank of Fig. 2 having its internal diameter tapering uniformly away from a maximum value at the centre 60. As the dies are closed parts 30A and B are bowed outwardly until points 40, 42 meet. Further closing of the dies forces the blank into firm engagement with the die walls and the ends of the blank into contact over their entire length, Fig. 18 (not shown). The formed rim is removed from the die and the seam formed by the two ends is welded, first at the seam ends, the ends of the blank being held slightly separated and then over the whole seam length.

Abstract: 1,054,103. Piezo-electric generators. HEINRICH MALTNER G.m.b.H. July 17, 1963 [June 1, 1963], No. 28277/63. Heading H2A. [Also in Division F4] A lighter comprises a spark gap 1 connected to two piezo-electric bodies 4, 5 and manually operated means for deforming the piezoelectric bodies to form a spark. The spark gap 1 has an earthed electrode 2 and an insulated electrode 3 connected to abutting ends 7 of the piezo-electric bodies. The latter are held in an insulating sleeve 6 in a sleeve 12 and may be adjusted longitudinally by a screw 13 acting through a ball 14 abutting a plate 11 at the free end of one of the piezo-electric bodies 5. The sleeve 12 is mounted on a handle 15 fixed to the housing 22 of the lighter. The piezoelectric bodies 4, 5 are deformed by a lever 19 pivoted at 20 to the handle 15 and adapted to press a ball 21 against a plate 10 abutting the free end of the other body 4. The lever 19 is actuated by a pin 18 on a movable handle 16 pivoted at 17 to the fixed handle 15. In Fig. 8 (not shown), which shows a cigarette lighter an operating lever 77 is connected to an arm 80 pivoted to the lighter body and spring- loaded to the position shown by a spring 82 which is connected to a lug 84 on a lever 83 pivoted about a pivot 76 of a cap covering the burner nozzle. One end 85 of the lever 83 abuts the underside of the operating lever 77 and the other end is formed with a cam surface 86 bearing against the top end of a vertical piezo-electric body 88 located in an insulated guide sleeve 90. The bottom end of the piezoelectric body abuts a screw. When lever 77 is depressed, cam 86 deforms body 88. In Fig. 10 (not shown) an L-shaped lever 109 pivoted at 108, when depressed by the operating lever 77 depresses a plunger 112 connected via a fluid 114 in housing 111 to a larger plunger 113 acting on a cap 107 of a vertical piezo-electric body. In Fig. 11 (not shown) a push sleeve 120 is disposed above a piezo-electric body 116 and contains a spring 121 biased against a mass element 122. A stop 123 on a spring- loaded pivoting lever 124 holds the mass 122 in the position shown. When sleeve 120 is depressed, spring 121 is tensioned until an edge 125 of sleeve 120 pushes lever 124 sideways releasing mass 122 to strike a cap 129 abutting the piezo-electric body 116. The piezo-electric bodies may be connected in parallel electrically or mechanically. The piezo-electric bodies may be of a ceramic material containing barium titanate and lead zirconate titanate and calcium titanate.

The closure is bored at 46 to receive, with clearance, a reduced portion 54 of a valveactuating spindle 52 which extends through the pillar housing. A valve closure 44 is spring loaded to close the lower end of the bore 46. To open the valve, the spindle 52 is pressed to open the valve closure 44 and relieve any pressure below the valve 32 after which the step 56 on the spindle opens the valve 32. When the spindle is released, the spring 48 closes valve closure 44 after which the valve moves slowly to engage seat 40.
