Abstract: A process for controlling the brightness (dimming) of a gas-discharge lamp (GE) which is located in a series resonant circuit (L1, C1) connected to a rectifier-inverter combination (10, 20), by varying the frequency (f) and the duty ratio (D, d) of the output alternating variable (uw) generated by the inverter and supplied to the gas-discharge lamp and to the series-resonant circuit (X; L1, C1, GE). The lamp (GE) is operated in a frequency range in which the dependency of the lamp power (Pab) on the frequency (f) of the output alternating variable (uw) can be represented by the duty ratio (D, d) as a parameter as a family of characteristic curves (K1, K2, K3, ...), each of which runs in the manner of a bell-shaped curve starting from a maximum value and reducing to form a point of inversion. The maximum value of the individual characteristic curves (K1, K2, K3, ...) of the family becomes smaller as the duty ratio (d1, d2, d3, ...) associated with these characteristic curves (K1, K2, K3, ...) as a parameter becomes smaller. The process is intended to be designed such that the brightness of a gas-discharge lamp can be varied in a stable manner without flicker. This is achieved in that the frequency (f) and the duty ratio (D, d) are in each case selected such that the operating point (B1, B2, B3, ...), with at least two characteristic curves selected or available for a specific lamp power (Pab), in each case coming to rest on that characteristic curve which has the lower gradient at this lamp power (brightness). <IMAGE>

Title: Continuous paper sheet tearing-up apparatus
Inventor: NAKAMURA FUMIHIKO
IPC: B65H35/10
Filed: 1989-12-29
Granted: 2000-01-25
Abstract: A continuous paper sheet having a plurality of transversal perforation lines and a plurality of holes formed in the longitudinal margines of the paper sheet. The paper sheet is torn by means of two pairs of nipping rollers including a pair of the upper and the lower feed-in rollers and another pair of the upper and the lower pulling rollers. The pulling rollers of the latter pair rotate higher than that of the feed-in rollers of the former pair so that the part of the sheet placed between the former pair of rollers and the latter pair of rollers are pulled or given tension, being torn and separated. After the continuous paper sheet is confirmed that it is placed on a stand at the predetermined position, the width or distance of the continuous paper sheet folded is measured. The resultant of measurement is compared to the standard sizes previously inputted in a CPU in order to correct it to the approximate standard size. According to the corrected standard sire and the sheet thickness separately measured, the tearing-up operation of the pairs of the feed-in rollers and of the high speed or pulling rollers is controlled in order to give the continuous paper sheet a difference in transferring speed and to tear-up the sheet at the predetermined position of the sheet.

Abstract: A recording and/or reproducing method and corresponding apparatus are provided, in which in phase monaural audio signals are separately mixed with a clock signal and a data signal, which are opposite in phase to each other, and the mixed signals are recorded in separate channels on a recording medium. Upon reproduction and recombination of the signals recorded in the two channels, the clock signal and the data signal cancel each other out so that the listener hears only the combined monaural audio signals but the clock signal and the data signal can be separated from the reproduced two channel recorded signals prior to their recombination and be used to generate visual display data concerning the recorded signals.

Title: Optical fiber electro-optical module
Inventor: EIDE JOHN E
IPC: G02B6/34
Filed: 1991-01-03
Granted: 1994-02-01
Abstract: ABSTRACT OF THE DISCLOSURE      An electro-optical module has at least three ports, with at least one port having an active electro-optical device for connection to electrical circuitry and at least one port having an optical port for connection to an optical fiber link.  A passive coupler interfaces the various ports.  The passive coupler is formed of optical fibers mounted on glass using an adhesive that exhibits refractive index-matching characteristics.  The fiber-on-glass coupler is extremely small, allowing for the module to have minimal size.  The coupler may be wavelength selective or wavelength insensitive.  If a wavelength-selective coupler is utilized, the end surface of an optical fiber is coated with a dichroic filter to provide wavelength sensitivity.  An optical fiber adapted to receive light for connection to a detector is selected to be a multi-mode fiber to increase reception of light.  The remaining fibers may be single-mode fibers.

Title: Valve for controlling the flow of pressurised fluid
Inventor: PETERSEN HANS C
IPC: F16K31/64
Filed: 1991-05-21
Granted: 1994-08-30
Abstract: Abstract In a valve for controlling the flow of pressurised fluid having a piston (4) and a valve seat (3), the piston (4) rests, in the closed position, with a front face (17) against a front face (18) of the valve seat (3).  When a pressurised fluid is supplied to the valve inlet, a leakage flow occurs between the front faces (17, 18).  At the same time, the pressurised fluid acts upon a portion of the piston surface (21) facing away from the front face (17) of the piston (4).  In order to permit reliable opening or closing of the valve, while having a simple design, it is ensured that an insert (19) that is deformable, by supplying a physical parameter, in such a manner that the gap between the front faces (17, 18) is enlarged is arranged in one of the front faces (17, 18) of the valve seat (3) and the piston (4), and that a spring (16) is provided that presses against the piston (4) in the direction towards the closed position.

Filed: 1991-08-01
Granted: 1995-02-07
Abstract: The apparatus for turning by 90°  a panel or a panel stack (P) on the cutting machine worktable (Q), comprises a withdrawable gripping means (1) which can be rotated around a vertical axis (2), and upon control is caused to clamp a panel  stack  (P)  close  to  one  of  its  rear corners.  The gripping means (1) is associated with shifting means (7) for the gripping means (1) to be caused to perform in a program-mable precise manner a rectilinear movement (3) near to, and away from the cutting line (Z) of the longitudinally cutting machine,  such that the panel stack (P) will be turned in clockwise or anticlockwise direction, depending on the panel stack (P) being clamped at its left-hand or right-hand cor-ner. Thus,  any cutting pattern,  such as a cutting pattern with a pre-cutting operation, for which a panel stack (P) needs to be turned by 90°, can be then carried out. A with-drawable pushing means  (4)  is caused to act on the panel stack (P) concurrently with the gripping means (1), by being moved parallel to the longitudinally cutting machine in a programmable precise manner, so that it helps in the desired turning of the panel stack (P). Differently from the known art,  a  lesser  floor  space  is  here  occupied  by  the conventionally  constructed  worktable  Q  for  supporting  a panel stack as it is being turned by 90.

Abstract: A self-expanding stent assembly consisting of one or more Z-stents connected to one another and covered by a flexible sleeve, which can be made from either nylon, plastic or another suitable material.  The stents are formed of stainless steel wire arranged in a closed zig-zag configuration which includes an endless series of struts that are joined by an equal number of joints.  The stent assembly is compressible into a reduced diameter size for insertion into, and possible removal from, a body passageway.  After being properly positioned within a body passageway, the stent assembly is allowed to expand to its larger diameter shape, wherein the sleeve is pressed against the walls of the passageway by the stents.  One application of the invention includes dilating a biliary duct which has been occluded by a tumorous growth.  The advantage being that the sleeve prevents the tumor from growing between the gaps created by the stent which would otherwise restenose the passageway. Another intended application is to repair aneurysms.  In this configuration, the stents are postioned on either side of an aneurysm, and the sleeve forms and artificial arterial wall which spans the aneurysm.
