Title: Cylinder lock with interchangeable key
Inventor: MATTOSSOVICH MARIA
IPC: E05B27/00
Filed: 1986-11-13
Granted: 1994-07-21
Abstract: The cylinder lock has a row of spring loaded sliders (21). Each slider (21) has teeth which engage the teeth of a second parallel slider (17). When the first slider (21) is depressed by inserting the key, the second slider is moved until a notch in its upper part is aligned with the projection of the bolt (25). The bolt (25) which is spring-loaded, slides radially inwards out of the notch (3) in the wall (2) of the housing to release the cylinder (8). The lock can be readily changed to suit a second key by rotating the cylinder (8) through 180 deg. with the first key. This has the effect of separating the two sliders (21,17). The second key is then inserted and the cylinder (8) turned through a further 180 deg.

Abstract: The method enables the gas boiler of the small output type to heat water rapidly. The method comprises the process of heating rapidly by working a proportional value (53) and a fan (23) harder than the ordinary time when the sensing temperature (WTth) is lower than the set temperature (STset) until water temperature reaches the set temperature.

Abstract: 본 발명은 브릿지만(Bridgman)법으로 망간-아연 페라이트 단결정을 성장할 때 성장되는 단결정의 고액 계면을 횡단하는 전류펄스를 일정하게 흘려줌으로서 고액 계면으로 발생되는 펠체 가열을 이용하여 계면에서의 온도구배를 제어할 수 있도록 한 펠체효과를 이용한 망간-아연 페라이트 단결정 성장 장치에 관한 것이다. 
     구체적으로는 제1발열체(1) 및 제2발열체(2)가 외부에 형성되고, 그 내측으로 하부에 알루미나 크레들(4) 및 알루미나 튜브(3)가 하부에 형성된 백금 도가니(5)를 설치하며, 상기 도가니의 싱부로는 원료공급장치(8)로부터 공급되는 원료를 도가니(5)로 공급하는 원료 공급 튜브(9)를 설치한 브릿지만식 단결정 성장장치에 있어서 상기 도가니(5)의 상부에 상부 전극(17)을 성피하고 하부의 종결정(18)에는 하부 전극(16)을 설치하여 상기 상,하부 전극(16,17)을 직류전류(14), 전류 펄싱유닛(13) 및 오실로 스코프(15)에 연결하여 단결정 성장중에 고액 계면에서의 온도구배를 제어하도록 한 것에 관한 것이다.
