Title: Apparatus for dimensioning slide fastener coupling elements
Inventor: DAKAHASHI KIHEI
IPC: B29D5/00
Filed: 1985-04-29
Granted: 1986-10-24
Abstract: A row of slide fastener coupling elements of synthetic resin metal is pressed between a pair of first and second pressor rolls having confronting press surfaces engaging legs of the coupling elements and spaced from each other by a distance equal to the width of the elements. The second presser roll is displaceable with respect to the first presser roll to vary the distance. The first presser roll has a spur gear held in mesh with a pin gear on the second presser roll to rotate in synchronism even when the second roll is displaced relatively. The first and second presser rolls also have partition ridges for meshing engagement with the legs to keep them spaced apart at equal intervals.

Title: Method and apparatus for level measurement with micor waves
Inventor: EDVARDSSON KURT D
IPC: G01F23/284
Filed: 1985-05-31
Granted: 1990-07-09
Abstract: A sweep generator (2) varies linearly the output frequency of a microwave oscillator (3). The oscillator output is applied to two mixers (4.5). One mixer (4) drives an antenna (6) directed downwards onto the surface (7) of a fluid to provide a measured signal. The second mixer (5) receives a signal from the oscillator, via a referece line (11) which acts as a delay, to provide a reference signal. The mixer outputs are amplified (8,12) and passed to a processing unit (10). The reference signal is filtered (14) and formed into a pulse for multiplication (17) controlled by a microcomputer (18). The sine and cosine values are applied to mixers (21,22) which receive the measured signal.

Title: Magnetic tape cassette having two layered portions
Inventor: SHIBA HARUO
IPC: G11B23/42
Filed: 1986-02-15
Granted: 1990-08-28
Abstract: The housing is formed with top and bottom halves, each of which has a two sheet structure in which a transparent or semi transparent layer (118) is laminated with a second layer (114) that can be opaque, transparent or semi transparent. The internal layer can be produced with a series of projections, such as fixing lugs (108) that are used to secure the housing halves together. The layer is produced by a moulding process. The outer surface layer is produced of a high strength material such as methacrylic resin or poly carbonate resin that reduces the possibility of surface scratches. When bonded in position the two layer structure produces a three dimensional display effect.

Abstract: A mobile telephony system intended for use by outdoor subscribers, for instance in cars, while affording, at the same time, high traffic capacity and relatively disturbance-free speech transmission to subscribers located within a building, for instance an office building. Signal transmission between mobile stations (MS, MSI) and base stations (BS1, BSI) is effected with radio waves in a first part-system (7), for instance intended for telephony traffic via car telephones, and with light, at least in the area nearest the mobile stations (MSI), in a second part-system (6) intended, for instance, for an office building. Signal transmission with light can also be effected in areas that contain electronic apparatus which is sensitive to radio disturbances, for instance in hospitals and/or in areas in which strong radio disturbances capable of preventing mobile telephony transmission with radio waves occur. Certain mobile stations may be capable of being switched between signal transmission with radio waves and signal transmission with light, which enables these stations to be used in both part-systems (7, 6).

Title: Sliding improve method of very fine thread fabric and knitted fabric
Inventor: AN BYONG-HUN
IPC: D06C23/04
Filed: 1991-08-28
Granted: 1993-06-29
Abstract: embossing  treatment  of  a woven or knitted fabric composed of fine-denier  yarns  in  a  way that the water content of the fabric be 20-100 % at the  embossing roller whose surface temp. satisfies the following equation  Tc  + 10 deg.C <= Tr <= Tc + 90 deg.C (where Tc; recrystallization temp. of polymer, Tr; surface temp.  of  the  embossing  roller),  after scouring the fabric and befoe dyeing it. The method  improves  the slippage property of  the  high-density  fabric  by  lowering  the friction coefficient of the fabric surface, while  leaving  intact of the smooth touch of the fabric.

Title: Electron gun for c-crt
Inventor: YUN NUNG-YONG
IPC: H01J29/48
Filed: 1991-12-17
Granted: 1994-06-20
Abstract: The electron gun includes a focus electrode having respectably a frontal three-polar-tube cathode, a controlling electrode, a screen electrode and a second electrode forming a quardrupole lens in case of deflecting an electron gun and a final accelerating electrode forming a main lens constructed near the first electrode, wherein outgoing side of the first electrode and the incoming side of the second electrode are formed in such manner that each central area of the electron-beam penetrating hole is protruding than electron-bean penetrating hole respectably as a step, thereby compensating for distortion by an ununiformed magnetic field of deflection yoke and increasing the characteristic of convergence by forming the polar lens asymmetrically and resolution of the cathode ray tube.

Title: Process for the preparation of e-oximethers from phenylglyoxylic acid esters
Inventor: WINGERT HORST DR
IPC: C07C69/738
Filed: 1991-12-30
Granted: 1999-08-02
Abstract: Process for the preparation of E-oxime ethers of phenylglyoxylic acid esters of the general formula I 
<IMAGE>
 in which the variables have the following meanings: 
 
  the substituents X and Y are selected from a group comprising halogen, C1-C4-alkyl, C1-C4-alkoxy or trifluoromethyl; 
  m is an integer from 0 to 4; 
  n is an integer from 0 to 3,
 and in which 
 
  a) a phenol of the general formula II 
<IMAGE>
 is converted into the phenolate, 
  b) the latter is mixed with a lactone of the general formula III 
<IMAGE>
 
  c) the molten mixture is reacted, and 
  d) the resulting 2-phenoxymethylbenzoic acid of the general formula IV 
<IMAGE>
 is converted, via the acid chloride, into the benzoyl cyanide and this is converted into the corresponding alpha-keto acid, which is converted into the compound I. 
 
 Alternatively, the compound IV can be converted, via the ester, into the beta-keto sulphoxide, which is reacted to give the beta-keto ester, which is subsequently converted into the compound I.
