Title: Adhesive applicator
Inventor: BRINKMEIER FRIEDHELM
IPC: B05C1/16
Filed: 1992-12-10
Abstract: ADHESIVE APPLICATOR     ABSTRACT           An  adhesive  applicator  comprises  a  transfer roller, a format roller provided with application members distributed over its periphery, in a predetermined format, and  a  collection  roller,  which  is  disposed before  the transfer roller in the direction of rotation.  In operation, portions of a uniform layer of glue are transferred from the transfer  roller  onto  the  format  roller,  and thence  to workpieces required to be coated with glue.  To prevent glue thrown from the application members from contaminating the apparatus and being lost as wastage, the collection roller is disposed before the transfer roller  in direction of rotation of the format roller.  The collection roller forms a troughlike nip with the transfer roller for collecting and holding the thrown glue for reuse.

Title: Optically non-linear active waveguiding material comprising a dopant having multiple donor--acceptor systems
Inventor: BATELAAN JAN G
IPC: C07C313/16
Filed: 1993-07-09
Abstract: ABSTRACT            The invention relates to an optically non-linear active waveguiding material comprising an optically transparent polymer and a non-linear optical dopant comprising more than one donor-.pi.-acceptor unit.   Dopants  comprising more than  one donor-.pi.-acceptor unit,  especially dopants in which the donor-n-acceptor units are positioned in a cyclic group, have  a  high  hyperpolarisability  and  a  charge-transfer absorption band wavelength which is about the same as that of dopants with only one donor-.pi.-acceptor unit.   Especially  suitable  dopants  for use  are  calix(4)arenes.  These are provided with acceptor groups at the upper rim and with donor groups at the lower rim. In addition to having excellent hyperpolarisability, these compounds were found to be readily soluble in host polymers, such  as  PMMA  and  polystyrene.  Because  of  their  charge-transfer absorption  band  at  a  low  wavelength,  optically  non-linear  active waveguiding structures containing such dopants are suitable for use as frequency doublers.            The invention further relates to hitherto undisclosed calix(4)arenes functionalised  with  nitrostilbene  groups,   cyanostilbene  groups, sulphonyl stilbene groups, sulphonate stilbene groups, azobenzenes or benzylidene aniline compounds.

IPC: A61F2/06
Filed: 1993-10-08
Abstract: A catheter has a tubular outer member which defines a lumen which receives an inner catheter member which defines a lumen to receive a guidewire.  A vascular support formed from a radially expandable permeable member mesh of braided fibers is fixedly connected to the inner catheter so as to form a proximal mesh cone at the proximal end and is connected to a tip on the distal end of the guidewire at its distal end.          After a period of use, the vascular support can be withdrawn by advancing the inner tubular catheter so that the distal end thereof engages the proximal mesh cone of the vascular support which is thus guided to retract and move within the inner catheter.

Abstract: Described is a plastic encapsulated electronic device having an integrated circuit unit, a lead frame and a plastic material encapsulating the IC unit and portions of the leads into a sealed package.  Each of the leads includes an inner portion adjacent the IC unit, an outer portion laying in a different plane than the inner portion, and a central portion interconnecting the inner and the outer portions. The plastic enclosure is so formed that the outer portion of each lead, except for its lowermost flat surface and a short outermost section, is embedded in the plasticmaterial. The bottom surface of the plastic enclosure is substantially coplanar with the lowermost flat surface of each lead. The short outermost portion of the outer lead portion extends beyond the plastic material for testing purposes. This arrangement provides for a robust encapsulation of the leads avoiding the prior problems of the prior art. Additionally, this device is especially useful for attaching the device to an interconnecting board by means of conductive adhesives.

Inventor: DIX MARK J
IPC: B65F1/14
Filed: 1994-03-24
Abstract: Apparatus are disclosed for securing an implement to a rigid longitudinally extended lifting member.  A representative embodiment comprises a clamp that can be mounted to a forklift implement and/or socket for receiving a lifting member.  A working surface engages the lifting surface of the lifting member.  A cam is pivotably mounted on an axis transverse to and displaced from the working surface. The cam has an outwardly radiating spiraled engagement lobe that presses against the under-surface of the lifting member so as to press the lifting member between the working surface and the cam.  Thus, the cam allows the clamp to be moved rearwardly but not forwardly on the lifting member.  The cam, which is biased, can be characterized by having a fixed axis, being self-locking, and/or having a constant contact angle with the underside of the lifting member.  The cam can also have a release lobe adapted to engage a reference surface for releasing the engagement lobe from the lifting member whenever the clamp is placed upright on the reference surface.  The clamp can have multiple cams either similarly or differently sized.  Differently sized cams allow the clamp to engage a wider range of lifting-member thicknesses than single-cam clamps.

Title: Spheronization process using charged resins
Inventor: MCCLELLAND GREGORY A
IPC: A61K9/16
Filed: 1993-06-22
Abstract: It has been discovered that charged resins impart qualities to a granulation which facilitate the preparation of spherical multiparticulates by the spheronization process. When charged resins are utilized, microcrystalline cellulose and other materials which have been used in the past to impart plasticity to the granulation may be avoided. The charged resin may have the added benefit of acting to modulate medicament release from resin modulated delivery systems.
