Title: Casting resins based upon acrylic-acid esters
Inventor: BERNHARDT GUENTHER
IPC: C08L33/06
Filed: 1985-12-20
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention relates to a casting resin made from an acrylic-acid ester in which a large proportion of finely dispersed fillers is mixed.  Accord-ing to the invention, the casting resin also contain a polymeric organosilicon compound which is the reaction product of a salt of (meth)acrylic acid with a copolymer of monomeric elements containing functional and non-functional groups.  The funtional groups in the copolymer are one or more alcoxysilyl groups and one or more (meth)acryloxysilyl groups.  Also polymerized into the copolymer is at least one functional comonomer having an ethylenically unsaturated arrangement and additionally, if necessary, a copolymer from the vinylcarboxylic-acid ester and (meth)acrylic-acid ester group.  The addition of such a polymeric organosilicon compound to a casting resin known per se causes substantial reduction in the viscosity of the resin which can be used to produce sanitary article mouldings.

Abstract: MAGNETIC RECORDING MEDIA AND SERVO SYSTEMS USING SAME               Inventors:  Vernon E. Ford Jeremy K. Jones John J. Mader William T. Plummer Abstract of Technical Disclosure Magnetic recording media, and magnetic recording systems using such media, are disclosed which incorporate a light-transmitting optical grating at least substantially coextensive with the magnetic recording area.  A second light-transmitting optical grating is associated with the magnetic transducer or read/write head.  A moire pattern is produced by light transmitted through both optical gratings, and changes in the moire pattern resulting from changes in the alignment of the optical gratings resulting from movement of the read/write head relative to the media are utilized to provide servo information to keep the magnetic transducer aligned with the magnetic track.          Higher magnetic recording capacities may be obtained using such media and systems, since none of the magnetic recording area is used for servo information.

Title: Dual sided pressure sensor
Inventor: KAIGLER WILLIAM J
IPC: G01L9/00
Filed: 1988-08-22
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE      A dual sided pressure sensor which is particularly useful for measuring differential pressures, comprises a diaphragm having top and bottom surfaces with pairs of strain gauges, both on the top and the bottom surfaces.  The two pairs of strain gagues are substantially at the same radial position on the diaphragm and preferably near the centre of the diaphragm or near an outer periphery of the diaphragm.  The sensors can be connected in a Wheatstone Bridge to measure pressures applied to the diaphragm which result in slight bending of the diaphragm. The bending applied compressive and tensile pressures to the two pairs of diaphragms for changing an electrical characteristic thereof.  The electrical characteristic normally changes in a non-linear fashion.  The non-linearity, however, for the pairs of gauges on the top and bottom surfaces are of opposite signs and equal magnitude so that they cancel each other to provide an accurate pressure measurement.          .

Granted: 1993-01-12
Abstract: ABSTRACT       A nonwoven web is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins.  A baffle plate may be inserted into the mixing zone and acts to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen.   When different fibrous materials are  fed  to  the  lickerin  along their  length,  the vertical composition of the web is altered.

Title: Digital filter tree
Inventor: GOECKLER HEINZ
IPC: H03H17/02
Filed: 1988-09-22
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE  The invention relates to a digital filter tree composed of a plurality of digital filter banks arranged in a tree structure one behind the other to branch out in stages with a separation into L? individual signals taking place in each stage and the sampling rate being reduced each time by the factor M? where ? = 1, 2, ... identifies the ?th stage. The filter tree employs a prototype filter with half-band functions for channel center frequencies f? = ?  B + B/2, with a real frequency multiplex input signal being separated into L? complex channel signals for further processing by means of a discrete Fourier transformation.  For all stages M?= 2 and L? = 4 are fixed, with only two signals of the L?          = 4 being utilized.  The arrangement permits adaptation of a hierarchical multi-stage method also to numbers of channels which are not equal to a power of two without changing the input sampling frequency and without the causing channels, whose number is fixed by the difference from the next higher power of two, to idle.

Granted: 1994-02-22
Abstract: ABSTRACT OF THE DISCLOSURE        A sort drink dispenser capable or rapidly dispensing carbonated beverages with minimized roa-ming action.  The syrup and soda are dispensed sep-arate from each other and allowed to mix upon the ice in a cup placed beneath the dispensing head. The dispensing or the syrup and soda is stayed to minimize roaming while achieving optimum beverage taste.  Syrup is dispensed from individual pumps which communicate with a bulk supply.  The syrup is consolidated in the pumps, preventing waste or the introduction of "slugs" into the dispensing line. The temperature of the syrup is monitored and com-pensation is made during the dispensing cycle to accommodate changes in viscosity. In generating soda, water is precooled and then introduced into an insulated tank where it is subjected to pressur-ized carbon dioxide.  In the pour head, a cluster of soda orifices are peripherally encompassed by syrup orifices, certain or which are angled to cause the syrup to convolute the stream of soda. The syrup is spaced from the soda and maintains a spaced relationship until entry into the cup or glass.
