Title: Process for the production of substantially pure gamma-butyrolactone
Inventor: WOOD MICHAEL A
IPC: B01D3/14
Filed: 1988-07-26
Granted: 1992-07-28
Abstract: ABSTRACT           A process is described for the production of substantially pure gamma-butyrolactone from a feed mixture containing a major amount of gamma-butyrolactone and a minor amount of diethyl succinate which comprises fractionally distilling the mixture in a fractionation zone in the presence of diethyl ethoxysuccinate and recovering from the fractionation zone an overhead vaporous product comprising gamma-butyrolactone which is substantially free from diethyl succinate and a liquid bottom product comprising diethyl ethoxysuccinate and diethyl succinate in admixture one with another.  This procedure can be used to separate a gamma-butyrolactone rich fraction obtained by distillation in one or more stages of a crude reaction product obtained by hydrogenation of a C4 dicarboxylic acid ester feedstock that contains a major molar amount of diethyl maleate and a minor molar amount of diethyl succinate, using a diethyl maleate feedstock from an esterification plant to provide diethyl maleate for use as feedstock for the hydrogenation process which is admixed with recycled diethyl succinate recovered from the fractionation zone.

Title: Apparatus for generating edge position signals for use in locating an address element on a mailpiece
Inventor: RADL BRUCE M
IPC: G06K9/00
Filed: 1988-10-06
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE The edges of address elements such as address labels and window apertures located on a mailpiece, are detected by utilizing illumination from first and second alternating "on" and "off" light sources which illuminate the address elements at an acute angle.  In the case of label detection, the edge closest to the on illuminating source generates a high contrast image, while the edge furthest from the "on" illuminating source is shadowed.  In the case of illumination of an aperture, the opposite is true.  That is, the light reflected from the edge which is furthest from illuminating source is high contrast, while edge closest to the illuminating source has a lower contrast.  When the images generated due to edge illumination by the left and right light sources are subtracted from each other, the edges are further enhanced due to the fact that the remaining portions of the images cancel each other out.

Granted: 1991-12-10
Abstract: ABSTRACT            A building  security  system  for  coupling  to  a building telephone  line  which  includes  a  building  subscriber telephone line connected to a subscriber telephone set on one end and to a central office line at the other end.  The central office line leads to a central office exchange.  The building security system controls communication between a central office exchange caller, a subscriber and a visitor at an intercom station in order to allow subscriber control of visitor entry and for allowing entry without subscriber control to authorized personnel.   The system includes a micro-controller, a non-volatile memory coupled to micro-controller  which  is  programmable  for  storing  system parameters including security entry codes and a building door latch of an entrance door which is coupled to the micro-controller.  The latch is operative in response to a control  signal  from the micro-controller  to unlock the associated entrance door.  A line relay is coupled to micro-controller for breaking direct connection of the central offices subscriber line and inserting in series with each of the latter a security system line which operates in response to a control signal from the micro-controller.  A visitor intercom station is coupled to the micro-controller and is connected to the subscriber telephone set through the system line in response to a control signal from the micro controller.  The intercom station has a key pad for manually entering data in response to which the micro-controller accesses the subscriber telephone set or operates the door latch if the data entered corresponds to a security entry code number stored in the non-volatile memory.

Title: Paper transport and paper stabilizing system for a raster line printer, plotter or the like
Inventor: BIBL ANDREAS
IPC: G03G15/00
Filed: 1989-03-10
Granted: 1992-08-25
Abstract: A PAPER TRANSPORT AND PAPER STABILIZING SYSTEM FOR A      RASTER LINE PRINTER, PLOTTER OR THE LIKE  ABSTRACT OF THE DISCLOSURE A vacuum transport belt for use in a multipass, multicolor raster printer has a vacuum attach means for providing a strong hold down vacuum force in the direction of paper travel for complete registration of a recording material with respect to a writing head and toner system.  The vacuum attach means comprises a thin metal strip bonded to a transport belt such that the surface of the strip is substantially flush with the surface of the belt.  A strong hold down vacuum is conducted through channels underneath the bonded strip to a series of closely clustered apertures which form a vacuum contact region on the strip.  The force of the vacuum applied at the contact region and the substantially flush contact between the surface of the strip and the transport belt tightly seals the entire surface of the recording material to the transport belt, thereby registering the recording material precisely to the transport belt in an invariant desired alignment with a writing head and toner system.

Title: Modified polypropylene resin composition
Inventor: OKADA TAKAYUKI
IPC: C08L51/06
Filed: 1989-03-30
Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE         The modified polypropylene resin composition of the present invention comprises a blend of a resin composition composed of polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copoly-merizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto a polypropylene, and modified polypropylene (A)/polypro-pylene (B) composition, and a saturated polyester resin (D), an epoxy group containing copolymer (E), and a basic compound (F) optionally added as a reaction accelerator.         The modified polypropylene resin composition according to the present invention is not only good in molding processability but also markedly effective in that it can give molded products much superior in physical properties to those obtained from individual polymers constituting the thermoplastic resin composition.   The novel modified polypropylene resin composition provided by the present invention can easily be processed into a molded product, a film, a sheet or the like by a molding method usually used for molding thermoplastic resins, for example, injection molding, extrusion molding or the like, giving a product which has a very good balance among stiffness, heat resistance, impact resistance, scratch resistance, coating properties, oil resistance, chemical resistance, water resistance, etc., and is excellent in appearance uniformity and smoothness. It can be advantageously used for a purpose requiring especially high heat resistance and impact resistance, in particular, low-temperature impact resistance.

Title: Compact force transducer with mechanical motion amplification
Inventor: LEE SHIH-YING
IPC: G01L1/14
Filed: 1989-08-15
Granted: 1993-11-23
Abstract: COMPACT FORCE TRANSDUCER WITH MECHANICAL MOTION AMPLIFICATION            Abstract of the Disclosure A compact force transducer has at least one flexible beam mounted at one or both its ends to a force summing member or members.  The force-to-be-measured is applied to the force summing member along a first axis generally transverse to the beams to deform the beam elastically, without overstressing, through a displacement d.  A sensor member carries a conductive surface and is coupled to the beam member.  In a parallelogram form, there are a parallel pair of beam members extending between two force summing members and a sensor member is secured to each beam member at or near its point of inflection.  One sensor member includes multiple arms that sandwich the other sensor member to produce a linear, push-pull mode of operation.  In a low cost cantilevered beam form, the sensor is coupled to the beam at the force summing member in a parallel, spaced relationship.  In a hybrid push-pull form, the transducer uses a two beam parallelogram construction with cantilevered sensors (1) coupled rigidly to each beam adjacent one force summing member with a hinge coupling between the beam and this one force summing member, and (2) extending generally in a parallel spaced relationship with respect to an associated one of the beams.
