Title: Antistatic composition
Inventor: MCKINNON ALAN J
IPC: D06M101/00
Filed: 1983-09-09
Granted: 1992-01-14
Abstract: A textile treatment composition comprises a water insoluble quaternary ammonium salt and a non-ionic surfactant containing at least one long-chain alkyl or fatty acid substituent and a hydrophilic group. The quaternary ammonium compound preferably has three large alkyl substituents of at least carbon atoms each and the surfactant may be selected from phosphine oxides, sulphoxides, or tertiary amine oxides, especially the latter. The compositions may be diluted with water and applied to textile materials especially wool, to give antistatic properties thereto. Compositions of the invention have lower soiling propensity than hitherto available compositions and they may therefore be applied to finished carpets, either in the piece or in situ applications.

Title: Tissue spectrum measuring probe
Inventor: HIRAMOTO JUNICHI
IPC: A61B5/00
Filed: 1985-04-02
Granted: 1989-11-25
Abstract: The outer surface of a metal ring is shaped so that its outer diameter diminishes stepwise, and is fixed under a protection sheath.  At lease one metallic lead wire is located in an opticfiber bundle under the sheath, and is incorporated into either of two waveguides for receiving reflected beams or for sending a projection beam.  By connecting a metal plug with a terminal, a weak electric current of high frequency is transmitted through a lead wire to the ring.  The latter is placed around the circumferential surface of the probe's measuring end portion so grounding the ring when attached to the surface of the object tissue.

Title: Process for manufacturing catalyst composition and process for polymerizing by use of the catalyst
Inventor: MCDANIEL MAX P
IPC: C08F4/62
Filed: 1985-05-16
Granted: 1993-03-27
Abstract: In one embodiment of this invention a surface silicated alumina composition, as opposed to conventional silica alumina, is provided. Such composition may also be fluorided and/or phosphated or phosphited. The resulting compositions are broadly useful but are of particular applicability as supports for chromium olefin polymerization catalysts. In another aspect alumina is fluorided and used with hexavalent chromium catalyst and a co-catalyst or in the alternative with an organochromium catalyst. If desired the support in this embodiment can also be phosphated or phosphited. In another embodiment, aluminum phosphate is formed in the pores of alumina. In contrast with alumina catalyst supports of the prior art, the supports of this invention allow for the production of olefin polymers at high rates of productivity. Also novel high density ultrahigh molecular weight polymers are produced.

Abstract: When a neck portion of the tube and a stem structure mounted with the electron gun are sealed to each other by heating, a distance between a standard level of the tube and that of the electron gun is measured.  Comparison/arithmetic processing is effected both on the measured value and on a previously stored standard distance to seek a difference between the two values. The tube body or the electron gun is controlled by a moving operation so that the difference falls within an allowable value. After this, the sealing process is carried out.

Abstract: 본 발명은 액정 라이트밸브에 관한 것으로서, 광도전층과 차광층과의 결합시 기계적인 결합특성을 개선하기 위해 광도전층을 개량한 것이다. 이는 화상신호를 담은 입력광에 의해 임피던스가 변화되고 비정질실리콘으로 된 광도전층과, 일정전위의 전압에 의해 입사된 출력광을 복굴절시키는 액정을 포함하는 복굴절수단층과, 상기 복굴절수단층과 상기 광도전층 사이에 개재되는 차광층 및 반사층과, 상기 복굴절수단의 구동전압을 제공하는 전극을 구비한 액정 라이트밸브로서, 상기 광도전층이 다결정실리콘으로 이루어지는 점에 특징이 있으며, 이로 인해 기계적인 결합특성이 개선되어 성능이 향상되고 제조비용이 절감되었다.

Abstract: The system for separating composite  synchronous  signal  and digital data from composite video signal in an optical video  disc system, comprises: a clamping circuit for clamping input composite video signal means for  separating  composite  synchronous  signal from the clamped composite signal, means for  separating  vertical synchronous signal from  the  composite  synchronous  signal,  and means for generating gate pulse and separating digital  data  from the composite synchronous signal and the vertical  data  from  the composite synchronous signal and the vertical synchronous  signal. Thus this invention can provide  static  vertical  and  horizontal synchronous signal and digital data  regardless  of  frequency  of video signal.
