Granted: 1992-07-14
Abstract: METHOD OF PRODUCING HOT ROLLED STRIP            ABSTRACT OF THE DISCLOSURE           Disclosed is a method of producing hot rolled strip having tensile strength values of Rm = 500 to 780 N/mm2 from unal-loyed or low-alloy steel having a carbon content of 0.3 to 0.9%.          A steel slab is austenitized and rolled into hot rolled strip which is cooled on a run-out roller table and then coiled.  A characterizing feature of the invention is that the hot rolling and the cooling of the strip on the run-out roller are performed in such a manner that the .gamma. /.alpha. transformation in the hot rolled strip starts only in the coil and finishes in the coil.  By this method, hot rolled strip having uniform properties may be produ-ced.

Abstract: Abstract of the Disclosure A slalom water ski comprises an elongated ski body and front and rear foot bindings mounted on the ski body.  The ski body includes a pair of assymetrical sides which provide the ski with a strong side and a weak side.  The strong side has a relatively sharp pivot point in the area of the foot bindings and extends inwardly toward the longitudinal centerline of the ski and the front and rear portions of the ski.  The weak side curves smoothly from the forward end to the tail end and extends generally parallel to the longitudinal centerline of the ski adjacent the front foot binding.  A beveled portion extends between each of the sides and the bottom surface, and the angle between the beveled portion and the bottom is greater on the strong side than on the weak side.

Abstract: ABSTRACT           One  method  for  manufacturing  double-diffused metal-oxide-semiconductor field effect transistor (DMOSFET) devices begins with forming an insulating layer having openings in its top surface on a semiconductor wafer.          Channel regions, well regions and source regions are then formed  by  two  stage  diffusions  of  impurity  materials through the openings.  The impurity materials are respect-ively of a different conductivity type from and the same conductivity type as the wafer.   Next, masks are provided on the surface area over the drain regions and the source electrode regions that are to be connected to the well regions and source regions.  An impurity material of the same conductivity type as the wafer is introduced into the channel regions by ion-implantation.   Gate,  source and drain electrodes are then formed.  The parameters in this process can be adjusted to allow the threshold voltage to be controlled to achieve a depletion type device.   The carrier concentration in the channel regions of the result-ing device is low compared to the carrier concentration in other parts of the well regions.  The result is a depletion type device with a high breakdown voltage.

Title: Operational method and control switching apparatus for monitoring the starting-cycle circuit of electric high-voltage motors with asynchronous start-up
Inventor: BREDTHAUER JUERGEN
IPC: H02P1/50

Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE         Operational method and control switching apparatus for monitoring the starting-cycle circuit of an electric high-voltage motor with asynchronous start-up.  A known operational method to protect electric motors from overloading determines rotor rotational speed and power input and compares them to stored, temperature-rise values assigned to operating condition data, in order to derive an accumulated total value, which corresponds to the relative temperature-rise condition of the motor.  The new operational method and the control switching operation for large high-voltage motors with a conversion of the starting losses in the rotor should guarantee an overload protection for the rotor parts affected during asynchronous start-up and in the stalled state, under consideration of their heating and cooling behavior, also in the case of these transient processes.  In the case of the operational method and the control switching operation to monitor the rotor parts of the high-voltage motor affected during start-up, the type and duration of the respective, also transient operating conditions, the stator current and rotational speed are determined and compared to operation condition matrices.  Based on a theoretical temperature-rise model, a temperature-rise condition matrix represents the time-dependent, dynamic temperature-rise behavior of the rotor parts affected during start-up by displaying discrete values, which are used to monitor the possible start-ups and to control the protective devices.  The method and apparatus are applicable to slipringless high-voltage asynchronous motors or high-voltage synchronous motors with asynchronous, high-performance start-up.

Title: Fail-safe thermostat for vehicular cooling systems
Inventor: KITCHENS JAMES L
IPC: F16K31/68
Filed: 1989-03-08
Granted: 1992-01-07
Abstract: Abstract of the Disclosure A fail-safe thermostat for vehicular cooling systems is positioned in a junction leading to an internal coolant passageway, a radiator passageway and a bypass passageway.  An open housing seated in the junction supports a fixed central rod extending into the wax filled interior of a movable cylindrical member which controls the position of the interior segment of a main valve. Expansion of the wax forces the cylindrical member in a first direction against a compression spring.  Fusible alloy is disposed in the coupling between the cylindrical member and the main valve, and melts at a specific temperature range in excess of the normal range.  When this occurs the coupling is released in such a way that the spring forces the valve member to a second limit position opposite to the direction of expansion.  A bypass closure member at one end of the cylindrical member may be used to close the bypass passageway concurrently with increased temperature.

Abstract: Abstract of the Disclosure A variable steam flow assembly for a steam iron includes a metering valve which does not depend on axial movement of a valve member with respect to a valve seat to control the steam flow rate, as in con-ventional metering valves, thus allowing the steam flow rate to be more accurately controlled.  The metering valve includes a cylindrical gasket having a transverse bore disposed intermediate the ends.  Longi-tudinal bores between each end of the gasket and the transverse bore define a plurality of flow passage-ways through the valve.  A valving member is rotatably received in the transverse bore.  Rotation of the valving member allows various flow passageways to be selected.  The valving member is mechanically coupled to a steam flow control knob disposed on the exterior of the steam iron housing.  The steam flow control knob is provided with a plurality of detent positions to allow a finite number of flow rates to be selected. A drip tube provided at the discharge of the metering valve prevents the valve member from being in direct communication with the steam generator.  This reduces the possibility of mineral deposits forming on the valve member due to spattering resulting from the boiling of water droplets in the steam generator; hence changing the flow rate.  The drip tube is pro-vided with longitudinal bores of smaller diameter than the gasket that determine the flow rate through the valve.
