Title: Turbocharger turbine wheel and shaft assembly
Inventor: BEDNARZ STEPHEN MICHAEL
IPC: F01D5/02
Filed: 1995-08-28
Granted: 2000-05-02
Abstract: A turbine wheel for a turbocharger or the like is mounted to an impeller shaft and optionally an additional drive shaft by annular rows of coupling teeth preferably of the CurvicTM coupling type having radially and rotationally locking convex sided and concave sided interlocking teeth.  Flexible webs connecting coupling rings on the turbine allow thermo and mechanical growth of the turbine wheel without excessive deflection of the coupling rings and the associated shaft flanges.  A single central stud threaded into one of the shafts and retained by a bolt against the other maintains the components in assembly with the coupling teeth fully engaged.  A radial slot formed in the coupling flange for one of the shafts prevents thermal distortion of the flange from substantially affecting an adjacent thrust bearing portion of the flange.  The arrangement simplifies rotor assembly and avoids the need for rebalancing after disassembly and reassembly.  The full width of the coupling teeth are available for the transmission of torque and radial alignment forces.

Title: Process for producing an adhesive bond in a folded joint
Inventor: EKLUND KARL-GUNNAR
IPC: F16B11/00
Filed: 1994-03-24
Granted: 2004-11-23
Abstract: The invention relates to a process for achieving an adhesive bond in a folded joint between a first component (1) and a second component (2), preferably of sheet metal. The components (1, 2) have essentially flat edge areas (3, 4), and the second component (2) has a bent-up edge flange (5) to be bent down about the edge area (3) of the first component (1). The process comprises application of an adhesive string (8) along the surface of the second component (2), which is to lie in contact with the first component (1). According to the invention, the adhesive string (8) is applied a short distance from the edge flange (5), and the amount of adhesive in the adhesive string (8) is adjusted so that the adhesive, when the components (1, 2) one pressed together, is forced past the edge of the first component (1) and covers the same. Furthermore a second adhesive string (10) is applied along die surface of the first component (1), against which the edge flange (5) is bent down. The second adhesive string (10) is placed a short distance from the edge of the first component (1) and the amount of adhesive is adjusted so mat the adhesive, when the edge flange (5) is bent down, is, on the one hand, pressed into contact with the adhesive in the first adhesive string (8), and, on the other hand, is made to cover the edge of the edge flange (5).

Abstract: A drive plate (E) for an automotive vehicle for transmitting a torque from a crankshaft (6) to a torque converter (7), while absorbing a thrust load applied from the torque converter to the crankshaft is formed with: a central mount portion (11) for mounting a crankshaft; an outer gear (20) formed in an outermost circumference of the drive plate; a plurality of weight reducing holes (30) formed between the central mount portion and the outer gear at regular angular intervals; and a plurality of the outer mount portions (12) for mounting a torque converter (7) formed near an outer circumference of the drive plate at regular angular intervals. In particular, the outer mount portions (12) are formed in such a way as to project radially inward from the outer gear (20) into the weight reducing holes (30), respectively. Since the virtual bending radius (deformation length L) of the drive plate can be increased, the bending angle (DA1) can be reduced when a thrust load is applied from the torque converter to the drive plate, so that it is possible to reduce a bending stress concentrated at the central mount portion (11) as small as possible, for prevention of the drive plate from being damaged.

Abstract: There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved.          In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other.  When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft.  The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft.  The other end portion of the EA plate is pushed into the internal-angle portion at a winding start end portion of the EA plate around the shaft to prevent the subsequential rotation of the spool in the webbing drawing direction with reference to the shaft.  Thus, when the webbing is prevented from being drawn, the webbing is drawn by a predetermined length, and energy absorption can be achieved.

Title: Visual power on indicator
Inventor: RODGERS BARRY
IPC: H02H1/06
Filed: 1995-10-13
Granted: 2007-07-17
Abstract: The present invention provides a low burden visual POWER ON indicator for a self-powered electrical circuit protection device.  The visual indicator includes a current transformer for producing an induced current in direct proportion to the current supplied to an electrical device protected by the protection device.  The induced current is summed and rectified.  An  energy accumulator stores a predetermined voltage required to operate the protection device. The stored voltage is controlled by an accumulation switch wich in turn is controlled by a hysteresis control circuit.  The hysteresis control circuit includes an operational amplifier which is biased by a stable reference voltage. When the voltage on the eneregy accumulator is equal to the stable reference voltage the operational amplifier produces a HIGH output signal. When the voltage on the energy accumulator is less than the stable reference voltage the operational amplifier produces a LOW output signal.  A HIGH output signal causes the power accumulation switch to close thereby diverting current away from the energy accumulator. A LOW output signal opens the power accumulation switch causing current to flow to the energy accumulator thereby charging it. An LED is electrically connected to the operational amplifier such that it is illuminated only when the operational amplifier produces a HIGH output signal and thereby provides a visual indication of the POWER on state of the protection device.
