Title: Dial lock
Inventor: LEE JONG-BOK
IPC: E05B37/02
Filed: 1984-08-30
Granted: 1986-09-30
Abstract: This lock consists of a locking unit, a locking pole(6), a bracket(7) , and a fixing plate(12). The locking unit is composed of a tablet(1) , a dial(2), a protecting plate(3), a supporting plate(4), and a seizing plate(5). Multiple tablet holes are made radially in a dial. A locking pole hole is made in the center of the plates. A locking tooth(6-1) is made on the hole and moves along the connecting holes(2-1a,4-1a,5-1a) of the plate(2,4,5). The clearance of the teeth is the same as the dial thickness and the number of the teeth is directly  related to the dials. The bracket(7) is conected with the pole and jointed with the lock home(8-1) of the ring(8). The dial numbers can be adjusted before locking.

Abstract: The bis(silyl)methanes of formula (III) or (IV) is synthesized by directly reacting mixture of chloro methyl silane of formula (I) and organic chloride of formula (II), and silicone in the presence of copper as catalyst at 250-350 deg.C in fluidized bed reactor or agitator of spiral type. R is hydrogen and chloroethyl group and alkyl group of C1-C4, and R1,R2,R3 is methyl or chloro group, respectively. A catalyst is added as 1-50 wt.% based on reactant.

Abstract: 이 장치는 원추형의 입구구간(2)을 가지는 관통하는 구멍을 가지는 하나의 안내장치(1)를 갖는다. 니이들몸체(3)는 안내몸체(1)의 구멍과 동축으로 정렬된 관통하고 있는 실도관(4)을 갖는다. 
     니이들몸체(3)의 일단부는 원추형의 입구구간(2)으로 뻗쳐있으며 원추형의 주위면을 가지며 이 주위면은  입구구간(2)의 벽과 함께 취입매질에  대한 진입간극(6)을 형성한다. 취입매질은 공급구멍(17)을 통하여 공급되며 이 공급구멍은 니이들몸체(3)를 둘러싸고 있는 링공간(18)에서 진입간극(6)앞에 유입한다. 
     안내몸체(1)와 니이들몸체(3)는 탄성의 힘 부하에 의하여 예를들면 스프링(11,12)에 의하여 서로에 대하여 압압한다. 
     이것으로 인하여 니이들몸체(3)에 관하여 안내몸체(1)의 축방향의 위치가 정확하게 고정되며 그리고 진입간극(6)은 정확하게 미리 정해진, 변동할 수 없는 폭을 갖는다.
