Title: Method for operating a glass melting furnace
Inventor: PIPE HELMUT
IPC: G21F9/16
Filed: 1989-12-12
Granted: 1993-03-20
Abstract: The invention relates to a process for operating a glass-melting furnace, in particular for the vitrification of waste materials polluting the environment, such as asbestos or asbestos-containing demolition material, sewage sludges, paint sludges, ashes, filter dusts and the like, a glass melt and, on top thereof, a mixed layer containing the waste materials being present in the furnace during operation, the mixture being fed from the outside into the interior of the furnace, the required heat energy being generated by heating devices in the glass-melting furnace, and the glass smelted from the waste materials and additives being discharged from the furnace through an outlet. A disadvantage here is that large quantities of waste gas, which have to be purified, are formed and that the energy consumption is high. 
<??>To improve the process, it is proposed to produce a liquid scum layer of alkali metal salt or alkaline earth metal salt on the surface of the glass melt and to maintain this in a layer thickness range corresponding to the particular operating states of the furnace by discharge as required and/or to maintain the mixed layer on the glass melt in a layer thickness range corresponding to the particular operating states of the furnace by controlled introduction and distribution of mixture in suitable compositions. 
<??>In this way, an improved heat transfer between the melt and mixture and extensive binding of waste gases into the scum and/or into the mixture are achieved.

Abstract: The machine is designed to replace the manual  production  of the jewel house with the mechanical production. A  metal  band  is fed to be cut into "U" shape and "I" shape. Units  of  "U"  shaped jewel house are  mechanically  produced,  aligned  in  series  and connected  with  the  pieces  of  "I"  shape  in  automation.  Any malfunction in the process actuates a magnetic  switch  to  detach the clutch od the drive shaft to stop the machine. One rotation of the drive shaft is to produce a jewel house and make one count for the counting of the products.

Granted: 1992-11-05
Abstract: The umbrella employs a simplified mechanism for automatically opening and folding the panel by actuation of a single push button to eliminate the failures often caused by the  complexity  of  the conventional mechanism. The improved mechanism includes an opening spring guide (2), a runner (3), an opening spring (4),  a  closing spring  (5),  inner  and  outer  cylinders  (6,7),  all  coaxially assembled on the shaft (1). The closing spring (5) housed  in  the cylinders (6,7) is stronger in force than the opening spring  (4). The pressing of the handle (30) prepares for  the  opening  spring (4) only to actuate the runner so that the pressing  of  the  push lever (18) opens the umbrella by releasing the spring (4) to  push the runner. Another  pressing  of  the  lever  (18)  releases  the stronger closing spring (5) to reversely actuate  the  runner  (3) for closing the umbrella.

Title: Method of transmitting different commands relating to the choice of transmitter-antenna in a time multiplex radio communication system
Inventor: ERIKSSON HAKAN O
IPC: H04L7/00
Filed: 1991-05-07
Granted: 1996-11-07
Abstract: The invention relates to a method for transmitting in a time multiplex radio communication system, for instance a GSM-type mobile telephony system, different commands from a movable station to a fixed station with respect to the selection of transmitter antenna in the fixed station. Each transmission sequence from the movable station includes a synchronizing word which consists of a predetermined number of binary bits. The different commands are transmitted by using different synchronizing words in dependence on the command to be transmitted. The movable station has access to at least two different synchronizing words. The synchronizing words used in addition to a standard synchronizing word are formed by the binary bits from the standard synchronizing word being shifted laterally to mutually different extents and/or in mutually different directions in order to generate different, new synchronizing words. In this way, there is formed in the receiver of the fixed station an impulse response having a pulse which occurs at different time points depending on which synchronizing word was used by the movable station.

Abstract: 고정판이 나머지 세 모서리와 상이한 형태인 한 모서리를 갖는 직사각형이므로, 밸브의 상부에서 정확한 삽입위치로 키이 고정되는 슬라이딩 게이트 밸브내 3-플레이트 시스템에 관한 것이다. 튜브 홀더나 하부 고정 유니트는 직사각형이어야 하며, 이는 동일한 형상(상호 거울상)의 대향 모서리 및 상이한 형상의 대향 모서리를 구비하는데 밸브 구조와의 결합 관계를 위해 동일하게 배치된다. 슬라이딩 게이트는 미국 특허 제4,415,103호에 기재되어 있는 바와 같이 비대칭 오리피스를 구비한다. 슬라이딩 게이트는 또한 역전되었을 때 게이트가 삽입될 수 없도록 단부와 상이한 여러 폭의 밸브내에서 이송 레일과 결합되는 비대칭 이송 레일을 그 하부에 구비한다. 또한, 상술된 비역전 특성외에, 본 발명은 삽입시 와류와 튀김을 억제하도록 고정판이 슬라이딩 게이트의 출구 방향으로 가장 긴 면과 비대칭 되는 것을 고려한다. 상기 슬라이딩 게이트는 튜브 홀더의 윗면과 상호 작용하는 표면상에서 비대칭이다. 이는 준비 위치에서 슬라이딩 게이트의 선단이 튜브 홀더의 후단과 겹치는 것을 용이하게 한다. 튜브 홀더 역시 비대칭이지만 가장 긴 면은 준비된 슬라이딩 게이트가 삽입되는 위치를 향한다. 따라서 작동시에 게이트가 로드될 때 슬라이딩 게이트부는 그 선단이 작동 중인 게이트의 후단과 접촉할 때까지 레일을 따라 통과한다. 이 때 슬라이딩 게이트의 전방 하부면은 튜브 홀더면의 후단과 겹쳐지므로 슬라이딩 게이트는 삽입을 위해 위치되었다가 제거되도록 이동된다. 삽입시에 퇴출하는 슬라이딩 게이트 내의 오리피스로 들어가는 스틸은 위쪽으로 전도되는 경향이 있으며, 고정판의 긴 길이가 상기 면적 이상이므로 튀김을 방지하기 위해 보다 넓은 표면을 제공한다. 또한 차단시에, 슬라이딩 게이트로부터 튜브 홀더를 통해 주형 내부로 배출하기 위한 설비가 제공된다. 최종적으로, 슬라이딩 게이트를 교환하기 위해 사용되는 단일 실린더가 튜브 홀더의 제거 및 교환을 위해 사용될 수 있도록 슬라이딩 게이트는 튜브 홀더의 길이와 동일해야 한다. 상기 밸브 자체는 전술한 내화물의 형태를 수용하기 위한 지지 및 프레임 수단을 구비한다. 또한 밸브는 슬라이딩 게이트를 구비하거나 구비하지 않은 채로 튜브 홀더 및 튜브를 위치로 상승시키므로써 수용하기 위해 준비된 플레이트 영역내 해제 가능한 로크 수단을 구비한다. 
     본 방법은 상부 고정판과 튜브 홀더 사이에 삽입된 단일 슬라이딩 게이트의 3-플레이트 슬라이딩 게이트 밸브내에 있어서 그 각각이 역전을 방지하도록 오프셋된 키이부와 결합하게 되는 방식으로 사용되도록 한다. 슬라이딩 게이트를 수용하는 방향으로의 상부판 선단이 수축되는 반면 상기와 동일한 방향으로의 튜브 홀더 판은 슬라이딩 게이트가 위치로 이동했을 때 튜브 홀더 판의 원위 단부에 과다한 굽힘 모멘트를 초래하지 않고, 일단 작동되면 상부판과 튜브 홀더 판 사이에서 이송방향으로 매끈하게 활주하도록 연장된다.

Abstract: The quinolone carboxylic acid deriv. is prepd. of formula (I) by reacting quinolone carboxylic acid of formula (II) with amine of formula (III) in the presence of unactive solvent or base solvent pref. at 50-190 deg.C for 1-48 hrs. under atmospheric pressure. In the formulas, R1 is hydrogen; R2 is C3-6 cycloalkyl or F1-2 opt. substd. phenyl; X is H or amino; A is N or C-Y; Z is the gp. of formula (A) where Q is SR3OR4 or NR5R6, R3 H or C1-4 lower alkyl, R4 is h or C1-3 lower alkyl, R5 and R6 are H or C1-3 lower alkyl. The obtd. cpd. of formula (I) has strong activity against not only gram negative bacteria but also gram positive bacteria.

Abstract: Disclosed is a method of forming necessary subject on metal surface. The method includes luster forming step, printing step, sanding step and ink removing step. The luster forming step is a step of forming luster on surface of target metal. And the printing step is a step of printing necessary subjects on the luster formed surface. In the sanding step sand the printed surface. The ink removing step is a step of removing ink adhered on the metal surface. According to the invention a certain appearance even though the metal is incorrodible like pure gold any appearance can be formed on the surface of metal, and there is no loss of metal and cause no pollution. And the subject printed in the surface do not wiped out.
