Title: Apparatus for assembling pairs of garment fastener elements
Inventor: DAKA YOUKIOU
IPC: A41H37/10
Filed: 1987-07-31
Granted: 1989-04-24
Abstract: The garment-fastener assembling device includes a combined supporting and connecting mechanism composed of a pivot lever rotatably mounted on a frame.  This is pivotably connected at its one end with the cylinder tube of a punch-driving cylinder and at the other end with a first pusher mechanism having a first pusher. A spring-biased slide rod is slidably mounted on the frame and has one end pivoted to the pivot lever adjacent to the cylinder tube. The slide rod is normally urged such that during a portion of the movement of the piston rod from the cylinder tube adjacent to the fully retracted position of the piston rod, the pivot lever operates the first pusher mechanism to retract and advance the first pusher.  With the combined mechanism thus constructed, a punch and the first pusher can be driven in an accurate timed relation to one another.

Abstract: Disclosed is a film or sheet material comprising a blend of (1) a crystalline propylene polymer composition which is comprised of, by weight, (A) from about 30 to 65% of a copolymer of propylene with a C4-8 alpha-olefin containing from 80 to 98% propylene, and (B) 35-70% of a co- or terpolymer of propylene with ethylene and, optionally, a C4-8 alpha-olefin having an ethylene content of 5 to 10% when ethylene is the sole comonomer and an ethylene content of 0.5 to 5% and a C4-8 alpha-olefin content of 1 to 9.5% when both ethylene and a C4-8 alpha-olefin are used as comonomers, and (2) an olefin polymer.

Title: Cloning and expression of microbial phytase
Inventor: ROBERT FRANCISCUS MARIA VANGOR
IPC: A23K1/165
Filed: 1990-09-27
Granted: 1998-11-16
Abstract: A nucleotide sequence encoding phytase has been isolated and cloned. The coding sequence has been inserted into an expression construct which in turn has been inserted into a vector capable of transforming a microbial expression host. The transformed microbial hosts may be used to economically produce phytase on an industrial scale. The compositions comprising phytase produced via the present invention may be used in a variety of processes requiring the conversion of phytate to inositol and inorganic phosphate.

Title: Asialoglycoprotein-conjugated compounds
Inventor: KIM JUNG-RYONG
IPC: A61K47/48
Filed: 1992-06-12
Granted: 1995-12-18
Abstract: The conjugated drugs (I) with sialoglycoprotein (II) consists of (1) separating orosomucoid protein (III) from Cohn fraction V of human serum, (2) treating (III) with neuramidinase to get (II), (3) cross linking (II) with glutaraldehyde and drugs (IV) to get (I). (IV) is selected from drugs for treating hepatitis B or C types containing interferon, Na acyclovir, ribavirin, vidarabine, anti-sense oligonucleotide, ribozyme, Ca leucovorin, glutathione. (I) which has high affinity to (II) receptors of liver cells and is absorbed into liver cells is useful for treatment hepatitis B or C.

Abstract: 표면경도가 높고 내구성이 뛰어난 고정밀도이고, 염가의 절삭공구를 제공함을 목적으로 한다. 
     공구본체(1)에 팁부착흠(2a)이나 센터구멍(9), 보스면(10) 등을 형성한 후, 공구본체(1)의 표면전체에 질화처리를 실시하여 경화층을 형성한다. 
     경화층의 경도는 공구표면으로부터 0.1mm의 위치에서 Hv500이상으로 하는 것이 좋다. 
     보스면(9)이나, 센터구멍(10)의 내주면은, 질화처리에 의해 생기는 연질 피막을 제거한 연마면으로 하여도 좋다. 
     팁주착홈(2a)은 질화처리 후의 마무리가공을 받지 않는 비가공면으로 하는 것이 바람직하고, 공구본체(1)에 형성되는 나사구멍 내부는 질화방지부로 하는 것이 바람직하다. 
     질화처리에 의한 경화층에 공구에 필요한 경도가 부여된다. 
     질화처리시에 왜곡이 생기기 어려우므로, 처리 후에 마무리가공을 시행하지 않아도 정밀도가 유지된다.
