Title: Combustion method and device of coal including high line
Inventor: SON JAE-IK
IPC: F23C10/02
Filed: 1986-08-02
Granted: 1989-12-02
Abstract: In a coal combustion method using a fluidized layer theory, high rich lime coal is separated and pulverized into grain size of about 10mm, and then supplied into the upper or lower portion of the fluidized layer.  Some of dispersed particles are promoted to burn by the phenomena of dispersion-depression and extension of the stay time at expanded cross-sectional freeboard, and thereby obtaining the high combustion efficiency.  The height of the layer can be controlled by exhausting the appropriate amount of the coal-ashes through te ash releasing device, on the basis of the sectional pressure signal indicating the height.

Title: Power transfer circuit inculding a sympathetic resonator
Inventor: BOSSI BURT J
IPC: B42D15/10
Filed: 1989-03-15
Granted: 1992-08-31
Abstract: A power transfer circuit includes first and second windings (L1,L2) sharing a common magnetic core (101). Each winding (L1,L2) has associated with it a parallel capacitor (C1,C2) to thus form a pair of "tank" circuits. The first winding (L1) is connected at one end to a voltage supply and, at the other end, to ground through an FET switch (100,200). The switch (100,200) is turned on and off at a predetermined frequency and at a 50% duty cycle. The second winding (L2) and associated capacitor (C2) achieves parallel resonance at the predetermined frequency. Similarly the combined first and second windings (L1,L2) and associated capacitors (C1,C2) achieve parallel resonance at said predetermined frequency. The second winding (L2) need not be electrically connected to the first winding (L1) which transfers energy to it through the magnetic core (101). The transfer circuit efficiently couples power across a dielectric interface to a pickup coil (L3). One particularly good application of the power taansfer circuit is in connection with a contactless Smart Card.

Abstract: A drawing machine for drawing a workpiece (41) comprises first and second drawing dies (42, 43), first and second push rods (45, 46, 47, 48) and first and second junction rods (53, 54). When the first push rods (45, 46) are downwardly moved, the first junction rod (53) is pressed and moved by the first push rod (45) to press the first drawing die (42). Consequently, the first drawing die (42) forms a first-stage drawn part in the workpiece (41). When the second push rods (47, 48) are downwardly moved, the second junction rod (54) is pressed and moved by the second push rod (48), to press the second drawing die (43). Consequently, the second drawing die (43) forms a second-stage drawn part in the workpiece (42). Thus, a plurality of stages of drawn parts can be formed by the same machine. A large number of holes (51, 52) may be provided in a junction die (55) for receiving junction rods (53), to insert the junction rods (53) in only prescribed ones of the holes. When the second drawing die (43) is changed in configuration or size, the positions of the junction rods (53) are also changed in response. Thus, jigs and tools can be efficiently exchanged in a short time in order to upper die with different patterns of drawing.

Title: Air regulating unit, the process for regulating air flow
Inventor: HOFSTETTER HANS
IPC: B65G53/24
Filed: 1988-06-24
Granted: 1996-08-06
Abstract: The new invention concerns the regulation of air volume in a conveying system comprising an air collecting line (37) in which the air volume and the corresponding air velocity, respectively, is regulated in the individual conveying pipelines (30-36) by a lifting body (4) resembling an airfoil. The latter works like a throttle flap and moves from an incidence angle ( alpha ,  beta ) of at least 10 degrees in the completely open position to 90 degrees in the closed position as a result of the lifting moments acting on it. The lifting body (4) itself regulates the air volume by means of blocking the air line cross section to a greater or lesser extent, wherein a balance is adjusted in every case between the air forces and lifting moments, respectively, which act at the lifting body (4) so as to be directed in a closing position and a counterweight (5) or countertorque, respectively, acting at the lifting body (4) in the opening direction. A responsiveness which has not been previously achieved can accordingly be achieved from every position and an optimal regulating characteristic, e.g. at an approximately constant air velocity, can accordingly be achieved independently of the air resistance occurring prior to the regulating unit.

Abstract: 폴리에스테르의 유리 전이온도는 임의의 이미드-함유 2산 단량체를 폴리에스테르에 혼입시킴으로써 증가될 수 있음이 밝혀졌다. 
     본 발명은 특히 (a) 디올 성분, 및 (b)(1) 하기 구조식을 갖는 적어도 하나의 이미드-함유 2산 단량체 약 1 내지 약 15 몰% 및 (2) 테레프탈산 또는 그의 에스테르 약 85 내지 약 99 몰%로 구성된 2산 성분으로 부터 유도된 반복단위들로 구성된 코폴리에스테르에 관한 것이다: 
     
       
     
     상기식에서, R은 알킬렌 그룹, 치환된 알길렌 그룹, 아릴렌 그룹 또는 치환된 아릴렌 그룹이다. 
     N,N' - 비스(1,3-메틸렌)사이클로헥산-비스(트리멜리트이미드)는 본 발명의 폴리에스테르를 제조하는데 이용할 수 있는 매우 바람직한 이미드-함유 2산 단량체이다.
