Title: Single-control mixer
Inventor: NIKOLAYCZIK HANS
IPC: F16K11/06
Filed: 1984-06-11
Granted: 1987-04-09
Abstract: The mixer fitting is formed with at least two discs, of which one serves as a static seat and includes two inlet ports for cold and hot water, as well as an outlet port. The second disc is shiftably mounted on the first and includes a mixing chamber cavity, dimensioned to partially or completely connect the inlet ports with the outlet port of the first disc. The mixing cavity in the shiftable disc is of asymmetrical form in relation to a symmetrical perforation pattern of the inlets and outlets in the first disc, so that the mid- position of the mixing cavity is designed to reduce the free flow cross sectional area of the inlet port for the cold water but the mixing chamber cavity is greater than the cross sectional area of the hot water inlet.

Title: Tracking control system
Inventor: FILTNER PREDRIC
IPC: G11B7/09
Filed: 1987-12-11
Granted: 1991-05-04
Abstract: In a CD player, a light beam for reading the information is focused onto the CD disc. Serving for this purpose is an optical scanning system with a laser diode, a plurality of lenses and a photodetector (P), onto which the CD disc reflects the light beam. By means of a track control system, the optical scanning system is displaced in the radial direction with respect to the CD disc, so that the light beam is taken along the spiral data tracks. Until now, offset voltages of the photodetector (P) have been compensated by manual adjustment of a potentiometer. In order to replace the laborious manual adjustment by an automatic compensation of the offset voltage, with an open control loop a compensation voltage is superimposed on the output voltage of the photodetector (P) and varied until the sum of the output voltage and the compensation voltage assumes a predeterminable value. The control loop is then closed. The track control system is suitable for playback devices which reproduce information from optical recording media in disc form, for example CD players and video-disc players. <IMAGE>

The cutting apparatus  comprises  the  vacuum  chamber  (11) having a plurality of fixtues (11a) for holding the CRTs; a  first vacuum pump (14) connected with a connection pipe having  a  valve (12) on; a second vacuum pump (15)  having  an  inlet  port  (15a) connected with the vacuum chamber (11),  and  a  discharge  outlet port (15b) connected with the inlet port (14a) of the first vacuum pump (14); a second valve (16) equipped between the discharge port (15b) of the second vacuum pump (15), and the inlet port (14a)  of the first vacuum pump (14).

Abstract: 파이프용 팽창공구(1)는 기본공구본체(2)와 그중의 하나가 팽창심봉을 작동시키는 두개의 핸드레버들(3)(12), 회전제어기구(10)를 통해서 회전하는 자유회전실린더(19)로 구성된다. 
     팽창심봉은 수동레버를 작동시킴으로써, 방사상으로 작동되는 팽창쐐기(16)와 세트와는 반대로 프리셋(preset)왕복운동시에 활주되면서 공구본체(2)로 부터 벗어난다. 
     자유회전실린더(19)는 작용력의 감소와 특정한 힘의 분배와 더불어 팽창심봉의 강제적인 인발이 허용되도록 어깨동축의 실린더축(19a)이 포함된다. 
     팽창심봉은 인발장치인 인발편(20)을 통해서 가동되는 제2회전핸드레버(12)에 연결된다. 
     인발편(20)은 회전제어기구(10)를 형성하는 캠이 달린 한가지 형태의 구조물에서 자유회전실린더(19)와 제2가동수동레버(12)상에 작용점들을 갖는 인장부로 구성된다. 
     제2형의 구조물에서, 
     회전제어기구(109)는 자유회전실린더(107)를 팽창심봉(105)의 두 개의 운동방향으로 유도하는 회전축(108)에서 곡형으로 활주하는 곡형의 슬릿(114)이 포함된다.
