Title: Thermal flattening semi-processed electrical steel
Inventor: SCHOEN JERRY W
IPC: C21D8/12
Filed: 1990-11-27
Granted: 2000-10-17
Abstract: The thermal flattening of grain oriented silicon steel which is in the semi-processed condition has improved magnetic properties after a stress relief anneal by using a low temperature and high tension flattening anneal. The flattening process is conducted at a temperature between1000 to 1435°F ( 540 to 780°C ) with a tension selected to produce a yield strength / tension ratio from above 5 to about 20 and preferably from 7 to 13. The yield stength of the material will vary depending on the length of the time at peak temperature but are typically from 400 to 4000 psi (29,200 to 292,000 gm/cm2). The material as thermally flattened will have at least about10% stress. After a stress relief anneal above about 1450°F ( 785°C ), the material has significantly improved core loss compared to conventional thermally flattened material. The material is particularly suited for wound transformer core applications.

Title: Shock absorbing motor mount for a rotary cutter
Inventor: DETTBARN DEKE
IPC: F16F15/06
Filed: 1990-12-24
Granted: 2002-04-02
Abstract: A shock absorbing motor mount for heavy duty rotary cutting machines commonly equipped with a frame and a hydraulic motor or the like mounted on the frame for driving a rotating cutting blade is disclosed. The shock absorbing motor mount includes a bearing for rotatably mounting the motor to the frame and a means such as a torsion arm for limiting the rotation of the motor with respect to the frame to permit an effective transfer of power from the motor to the cutting blade and normally maintaining the motor at a neutral position. The means for limiting the rotation generally includes a resilient shock absorbing means such as compression springs mounted on one end of the torsion arm for progressively decelerating the rotation of the motor when the cutting blade strikes an object which possesses sufficient inertia to induce a rotation of the motor with respect to the frame, and for returning the motor to the neutral position.

Title: Method of preparing cemented carbide or cermet alloy
Inventor: KITAGAWA NOBUYUKI
IPC: B22F3/00
Filed: 1990-09-12
Granted: 1999-08-03
Abstract: A method of preparing a cemented carbide or a cermet alloy by mixing and kneading cemented carbide powder or cermet alloy powder with an organic binder, shaping this mixed powder into a prescribed configuration by an injection molding method and thereafter removing the organic binder from this compact and sintering the same, in order to obtain a dense alloy. Removal of the organic binder is performed in a first step in an inert gas atmosphere as a first removal step, and continued under a vacuum of not more than 1 Torr as a second removal step. In the first removal step, the pressure is held in excess of atmospheric pressure, to prevent the formation of imperfections in the compact. After continuous pores are formed in the interior of the compact, the pressure is brought close to a vacuum, thereby facilitating the evaporation of gas from the surface and desorption of gas generated in the interior of the compact.

Title: Method of driving a matrix-type liquid crystal display device
Inventor: ONO JYUNICHI
IPC: G09G3/36
Filed: 1991-12-18
Granted: 1998-07-07
Abstract: A method of driving a matrix-type liquid crystal display device utilizes a liquid crystal layer sandwiched between a plurality of scanning electrodes and a plurality of signal electrodes extending generally perpendicular to the scanning electrodes.  A display is erased by bringing it into either a light transmitting state or a light scattering state, and then selectively writing pixels at each intersection between the scanning and signal electrodes to reverse their optical state. The pixels are retained in their optical states after the writing step.  During the erasing step, all of the pixels are subjected to a high alternating voltage or a high direct current voltage.  During the writing step, the scanning electrodes are line-sequentially selected and the signal electrodes receive a signal of a waveform effective to apply a high voltage to those pixels desired to be reversed and a low voltage to those the pixels desired to be unchanged.  During the retaining step, a low alternating voltage or a low direct current voltage is applied to all of the pixels.

Abstract: A limit device for preventing travel of a hoist lift rope load above a predetermined height.  The limit device includes an actuator mounted at a reference position adjacent the hoist lifting rope as it is raised and lowered by a prime mover.  A switch is connected in a control circuit for the prime mover to place the prime mover in either a raise-lower mode or a raise-prevent mode.  A switch actuating mechanism is connected between the actuator and the switch and is operatively connected to maintain the prime mover in its raise-lower mode when the actuator is in its reference position.  A follower is mounted at any desired fixed position on the lift rope for travel therewith.          Lifting of a load above a predetermined height will result in the follower contacting the actuator to move it from its reference position and cause the switch to place the prime mover in its raise-prevent mode and stop further lifting of the load.

Title: Current leakage control for electrosurgical generator
Inventor: MCELHENNEY JAY J
IPC: A61B/
Filed: 1991-09-24
Granted: 1997-12-09
Abstract: A  current leakage control circuit (115) regulates the output power of an electrosurgical generator (20) to limit the amount of leakage current. The leakage current is monitored with a differential transformer (90) which has the output lead (30) and return leads (80) of the electrosurgical generator (20) as first and second winding (96). A third or sense winding (100) produces a control signal whenever the currents in the output and return leads (30, 80) are not equal, thus indicating current leakage. The control signal is compared to a predetermined maximum safe level of leakage current. If this predetermined level is exceeded,  a power control feedback loop of the eletrosurgical generator reduces the output power to a sufficiently lower level to reduce the leakage current within  a  maximum acceptable limit.
