Title: Process for recovering vinyl polymers from emulscir pelymerization latices
Inventor: HUDDESTON GEORGE RICHMOND JR
IPC: C08F14/06
Filed: 1981-03-02
Granted: 1984-06-15
Abstract: Polymerization of vinyl or vinylidene halides comprises forming a monomer premix in an aq. medium with a free radical initiator and an emulsifier and then homonizing the premix. The premix is polymerized at a temp. of 30-70oC at pH 3-12 to produce vinyl polymer latex in a reaction zone. The latex is then stripped by steam from an unreacted monomer and a coagulating agent is added to the latex at pH 2-8 to form a slurry of friable agglomerates of polymer particles in serum. The serum is removed under pressure through a permeable membrane and a wet cake polymer is obtd. and rinsed of residual compds. The wet cake is crumbled to form friable polymer agglomerates and particles, then heated air is injected at 50-80oC and 2.5-80 psig. into the mill.

Title: Fastener
Inventor: KILL PETER JOHN
IPC: F16B23/00
Filed: 1981-07-21
Granted: 1985-06-26
Abstract: The fastener driving recess has at least three radial grooves extending out from a central cavity and tapering toward the base of the recess. The driver has the same number of radial wings projecting from a central core, tapering radially toward the nose at an angle not less than the taper of the grooves. The width of the wings at the upper edge of the corresponding width of the grooves. This allows the driver to move angularly about its axis in the recess to ensure driving contact at the upper outer edges of the recess. The width of the groove tapers toward the recess base so that the nose ends of the driver wings are confined in the grooves, to provide stable engagement. The nose ends of the wings pref. wedge in the grooves.

Abstract: 본 발명의 구동 슬립 제어 시스템은 각 실린더에 대한 작동 매개물의 공급을 순간적으로 차단하고 또한 각 실린더를 위한 점화를 방해하거나 또는 지연하는 것을 일시적으로 감소시키므로써 수행되는 것에 관한 것이다. 
     이러한 제어 시스템에서, 전자 가속기의 드로틀 밸브 조정기와 비교하면 매우 낮은 비율의 조정기를 갖는 드로틀 밸브 조정기가 중복 사용되고, 저속 조정만을 허용하고 계속하여 이러한 제어가 연장된다면 효과적으로 실행되는 작동기로 구성되어 있다.

Title: Making method of gear
Inventor: JONG UN-JO
IPC: B23F21/00

Granted: 1993-11-11
Abstract: The method can manufacture gears precisely by comprising gear threads made of brass that has  a  good  workability.  The  method comprises three steps: (a) form a shaft with a disc (1)  on  which many long grooves (4) and ring-shaped grooves (3) are bored out at the first cast; (b) form brass layer (5) at the circumference face of the disc (1); (c) and machine the gear threads from  the  brass layer. This method forming a shaft  and  a  gear  body  integrally makes the manufacturing of gear convenient and precise.
