Title: Amino-substituted benzenesulfonylureas and -thioureas, processes for their preparation, and their use as pharmaceuticals
Inventor: ENGLERT HEINRICH
IPC: C07C311/58
Filed: 1994-12-06
Granted: 2005-10-18
Abstract: There are described amino-substituted benzenesulfonylureas and -thioureas of the formula I (see formula I)   The compounds I are used for the treatment of cardiac arrhythmias and for the prevention of sudden heart death caused by arrhythmias and can therefore be used as antiarrhythmics. They are particularly suitable for those cases in which arrhythmias are a result of constriction of a coronary vessel, such as in angina pectoris or in acute cardiac infarct.

Abstract: A process for producing an apertured nonwoven fabric combines one or two outer nonwoven layer(s) with a layer of polymeric material having a lower melting temperature and a property of shrinking when melted.  Heat and pressure are applied through a calendar roll such that the polymeric material  becomes  bonded  to the  fibers  of  the  nonwoven layer(s)  and simultaneously shrinks and takes back the fibers away from the calendaring points, thereby generating apertures through the nonwoven fabric.   Preferably,  the fibers are polyethylene or polypropylene fibers, and the layer of polymeric material  is  a thin plastic film of polyethylene  stretch-wrap,  elastomeric,  or  heat  shrink material.  One outer nonwoven layer may be combined with the plastic film layer to form a bi-laminate product, or two outer nonwoven layers may be combined with an intermediate plastic film to form a tri-laminate product.   Low denier polypropylene/polyethylene bi-component fibers or a blend of higher and lower melting fibers may also be used.  Apertured products can also be obtained with non-thermoplastic outer layers and an intermediate plastic film layer.

Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container.  The lid latching mechanism features a large, trapezoidally-shaped opening hole.  The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process.  The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member.  The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.

Abstract: In order to permit a printing form to be produced by means of laser-induced thermotransfer in a simple manner  that  can  be  integrated  into  the  printing machine,  without the gases which arise during laser imaging detectably disturbing the transfer of material from the transfer foil,  i.e.,  the image quality,  a strip-type transfer foil 8 with a strip width b that is  small  relative to the printing form width B  is used.    During  imaging,  this  transfer  foil  8  is conveyed continually between the printing form 1 and the laser beam,  close to the printing form surface, and is thereby moved simultaneously and synchronously with  the  movement  of  the  laser  beam  across  the printing form width B.

Abstract: A variation in the cross-correlation between current received signals of different channels is extracted which corresponds to the cross-correlation between previous received signals, and the extracted variation is used as an adjustment vector to iteratively adjust the estimation of the impulse response of each echo path.  Furthermore, by additionally providing a function of actively varying the cross-correlation between the received signals to such an extent as not to produce a jarring noise, it is possible to reconstruct  acoustic signals by individual loudspeakers and utilize received signal added with the cross-correlation variation to obtain the adjustment vector for an estimated echo path vector.

Title: Communications privacy protection system
Inventor: LONDON THOMAS BENNET
IPC: H04M3/48
Filed: 1996-01-23
Granted: 1999-05-11
Abstract: A telephone subscriber of a privacy communications service is allowed to use a randomly selected non-assigned telephone number -- instead of the subscriber's real telephone number --as a return phone number in a telephone message left for a called party. The non-assigned, randomly selected telephone number becomes inoperative after a threshold that may be pre-imposed by the subscriber is exceeded. According to a feature of the invention, the function ofrandomly selecting a non-assigned telephone number may also include replacing the calling party number with the randomly selected number. Hence, when a caller-id display unit receives the telephone number of an incoming call for which the privacy communications service is used, the randomly selected telephone number -- as opposed to the real telephone number -- is received and recorded by the caller-id display unit.

Title: A drawer slide latch
Inventor: O'NEILL KEVIN
IPC: A47B88/493
Filed: 1996-05-23
Granted: 1999-08-03
Abstract: The present invention relates to a drawer slide assembly with an integral latch mechanism to inhibit inadvertent opening of a drawer. The structure of the present invention comprises an outer slide member and an inner slide member. The inner slide member is slidably engaged to the outer slide member. The structure includes an aperture in one of the slide members. A bearing is positioned to removably engage the aperture when the drawer slide assembly is in the closed position thereby forming a latch detent mechanism. The bearing is resiliently seated in a bearing retaining structure mounted on the drawer slide structure. The bearing retaining structure is provided with means for providing a biasing force onto the bearing. This biasing force urges the bearing toward engagement with the aperture. When the bearing engages the aperture the inner slide member is held against slidable movement with respect to the outer slide member. This engagement provides for a secure latch to hold a drawer against inadvertent opening. The force necessary to disengage the latch is dependant upon the biasing force put upon the bearing.

Abstract: The pipe bending machine comprises a bending template (15) for bending the pipe therearound. The unbent pipe portion is supported on a pipe supporting rail (20) mounted on a pipe supporting rail carrier (25) and being adjustable in height. The height adjustment of the pipe supporting rail (20) is performed by a drive means (28), suited for stepless positioning, which sets the pipe supporting rail (20) to a height predetermined by the CNC control unit. Prior to the bending of the pipe, the height to which the pipe supporting rail (20) is to be moved is determined by the working program in dependance on a set of tool data which has been input into the control unit.

Title: Multi-purpose tool including folding scissors
Inventor: BERG HOWARD G
IPC: B26B13/22
Filed: 1996-08-21
Granted: 1999-06-08
Abstract: A multi-purpose folding tool including a pair of folding scissors, in which a scissors blade is movable about a pivot shaft, between a stowed position and a deployed position in which a stop prevents the blade from moving further with respect to the handle because of pressure on the handle in the direction needed to close the scissors blades in a cutting stroke.  A rocker is moved by a spring in the tool handle and which in turn urges a movable scissors blade toward an open position. In one embodiment two handles are folded about respective scissors blades to house the blades, and four springs hold the handles together with the folded scissors stowed within the handles.  when the blades are deployed one of the springs holds each blade in position with respect to the handle while the other spring urges the blades toward an open position, through action of a rocker.  When the scissors and other tools are folded into their stowed positions in the handle of the multi-purpose tool of the invention the tool has a smooth outside configuration allowing the tool to be carried in a pocket without causing undue wear.

Abstract: In an optogalvanic spectroscopy system a plasma is exposed to light at a wavelength associated with a particular species in the analyte. The light is amplitude modulated. The amplitude of a modulated component in the signal representing electrical impedance of the plasma is detected in a phase independent manner so that the detected amplitude is substantially independent of the phase of the modulated component in the impedance signal relative to the amplitude modulation of the light. The system has reduced sensitivity to changes in the spectrum of the applied light.
