Title: Apparatus and method for controlling the air/fuel ratio of an internal combustion engine.
Inventor: EARLESON WALTER E
IPC: F02P15/00
Filed: 1990-02-20
Abstract: In the subject invention an electronic control unit is used to control the air/fuel ratio in an engine combustion chamber in response to sensed engine parameters. More particularly, a magneto interface produces an ignition signal which is delivered to a spark plug. The spark plug is disposed essentially in the center of a combustion chamber, and it ignites an air/fuel mixture in the chamber in response to the ignition signal. A sensor such as an ion probe, for example, is further disposed in the combustion chamber longitudinally from the spark plug. The sensor produces an ionization signal in response to a flame front propagating past the sensor. A buffer circuit receives the ignition and ionization signals and produces a combustion signal in response to a time difference between the reception of these signals. The electronic control unit receives the combustion signal and calculates a combustion signal air/fuel ratio in response to the combustion signal. Both the combustion signal and the combustion signal air/fuel ratio are responsive to changes in the quality of the fuel in the combustion chamber. Subsequently, the control unit calculates a volumetric air/fuel ratio. The volumetric air/fuel ratio is indicative of the volume of air and fuel in the combustion chamber, and it does not account for fluctuations in fuel quality. Finally, a wastegate is controlled in response to the volumetric and combustion signal air/fuel ratios.

Title: Process for transferring designs to a backing.
Inventor: HAGEDORN JUERGEN
IPC: B41M5/382
Filed: 1990-06-26
Abstract: A transfer sheet is used for transferring an image formed by electrostatic copying to a backing of textile fabric or other porous material. The transfer sheet is composed of a plain paper substrate having no release treatment or coating applied thereto, and a transfer coating of thermoplastic polymeric film material bonded to the substrate. Transfer of the image is accomplished using only the single transfer sheet. The plain paper substrate securely retains the polymeric film coating during electrostatic imprinting and avoids contamination of the copier/printer. The image can be transferred to a textile backing by applying heat of about 160° C. and 200° C. and pressure of about 50 psi for a duration of about 5 to 10 seconds, and results in a high-quality image transfer that leaves the fabric weave open to breathe. The plain paper substrate is removed after image transfer by peeling it away from the backing while still hot.

Abstract: An output buffer for reducing switching induced noise in high speed integrated circuit devices incorporates a relatively small current carrying capacity secondary pulldown transistor (N1) element with the current path first and second terminal leads coupled in parallel with the current path first and second terminal leads of the primary pulldown transistor element (N3). A first output voltage sensing switching circuit (P4) is coupled in series between the control terminal leads of the secondary (N1) and primary pulldown (N1) transistor elements. The secondary pulldown transistor (N1) element control terminal lead is coupled in the output buffer to receive a signal propagating through the output buffer first. A relatively small discharge current is therefore initiated from the output before turn on of the relatively large discharge current of the primary pulldown transistor element (N3). The first output voltage sensing switching circuit delays turn on of the primary pulldown transistor (N3) element until a threshold voltage below high potential is reached at the output. As result ground bounce and undershoot are each divided into two spikes and the ground rise in potential is constrained to approximately one half that of conventional ground bounce levels. A secondary pullup transistor element with associated noise reduction components can similarly be used on the supply side to reduce V CC  droop and overshoot including a second output voltage sensing switching circuit.

Abstract: The table tennis bat has differently shaped grip shells (14, 16), by which the forehand and backhand sides of the blade (10) are defined. In contrast to known anatomical grips, however, the grip shells (14, 16) have very simple geometrical shapes. With the grip shaped, in the central region, substantially symmetrically to the medium lengthwise axis, the grip shell (16) on the backhand side is designed with an approximately uniform thickness up to its leading edge (22). It also extends beyond the forward-chamfered front end of the grip shell (14) on the forehand side. In order nevertheless to be able to attach coverings of equal size on both sides of the blade, the front region of the grip shell (16) on the backhand side is undercut. <IMAGE>

Abstract: A nut fastener device for a blind hole anchor has the nut 14 made frusto-conical with the smallest diameter knurled at 30 and with the largest diameter provided with relieved and back tapered flanks 20. The nut is made integral with a sleeve 10 having flange 12 and a further knurled zone 32, and a sheer zone 16 between the sleeve and nut. During the installation the nut is pulled into the sleeve to expand the sleeve and deform it to the cross sectional shape of the nut so as to provide an angular fix. The sleeve is effectively fixed to the sheet material by the flange on the one side and the deformation of the sleeve on the other side of the sheet. The knurled bands which become axially aligned increase the angular hold of the device in the sheet and of the nut in the sleeve.
