Title: Gamma matched, helical dipole microwave antenna with tubular-shaped capacitator
Inventor: RUDIE ERIC N
IPC: H01Q9/16
Filed: 1994-08-12
Abstract: A catheter shaft carries a coaxial cable (220), the terminal end of which contains a dipole antenna (214) with opposing first and second helical elements (214A, 214B). This first and second helical elements (214A, 214B) originate from a common connection (222) to an outer conductor (224) of the coaxial cable (220). A tubular-shaped capacitor (200) is connected between an inner conductor (218) of the coaxial cable (220) and a point (232) on the second helical element (214B) where the resistive component of the antenna's impedance matches the characteristic impedance of the coaxial cable (220). This match minimizes reflective losses of the antenna (214), thereby maximizing power transfer to the antenna (214). The antenna (214) has an effective electrical length which is equal to one half the wavelength of the radiation emitted, independent of the physical length of the antenna (214).

Filed: 1996-02-27
Abstract: A  feeder  and method  are  disclosed  for  individually dispensing surface-mount contacts in a strip of tab-connected contacts on a pick-and-place machine having a pick-up member and pick-up station actuator for actuating the feeder when the pick-and-place machine is  ready for pick-up surface-mount contact oriented along a predetermined direction at the pick-up station.  The strip of contacts are fed from a roll or spool and the end received within a guide, with the strip being advanced to position the end contact or connector to be mounted suspended beyond the guide.  When the component is ready to be mounted, it is sheared or severed at a connecting tab from the strip to free it.  The component is temporarily held in place while the freed component is moved towards the vacuum pick-up nozzle of the pick-and-place machine, and released at such time that the pick-up member of vacuum nozzle has sufficiently engaged the contact to enable it to pick up the contact and remove it from the pick-up station. A control circuit, using a PLC, obtains signals from a series of sensors to regulate the cycle of advancing and sensing the strip of contacts with a series of actuators in the form of solenoids, which cycle is commenced when a pick-up nozzle of a surface mounting machine is sensed at the pick-up station. The tension of the strip is regulated by the control circuit, and a collection system is provided to remove cut off fragments of connecting tabs or carrier strips from the pick-up station.

Filed: 1996-09-26
Abstract: A method for producing visible marks in molded contact lenses, particularly soft hydrogel contact lenses, by placing a recessed mark configuration in a metal insert. The metal insert is subsequently used to produce injection molding frames, which are then subsequently used in the molding of the final contact lenses. The recessed mark configuration is at lest approximately 10 microns deep, has a Volume Index, which is the ratio of the quantity volume below a reference surface minus the volume above the reference surface over the volume below the reference surface, of at least approximately 0.9. The recessed mark configuration also preferably has a ratio of surface roughness (RMS or Ra) to a peak-to-valley (PV) measurement, RMS/PV or of Ra/PV, of greater than approximately 0.15. The recessed mark configuration in the metal insert is subsequently transferred as a raised portion to the injection molded frames, and is then subsequently transferred as a visible recessed mark in contact lenses molded in the frames prepared using the inserts. The ratio of the surface roughness (RMS or Ra) to the height (H), wherein H is the distance between two reference lines in a profile of the mark, RMS/H or Ra/H, is at least approximately 1.5. A preferred method of imparting the recessed configuration to the insert is by Electric Discharge Machining (EDM). The dimensions of the several parameters can be verified by using a noncontact scanning white light interferometer.

Patent CA-2189066-A1 (CA)
Title: Bag separator and dispenser
Inventor: MORRIS JOSEPH W
IPC: B65D33/00
Filed: 1995-06-09
Abstract: A bag dispenser, for separating and dispensing a series of plastic bags where one end is attached to the top of the next bag by perforation lines with a slot therebetween. The series of bags are dispensed from a device comprising a wire frame formed into channels to support the core that the series of bags ate rolled onto. The channels allow the core to rotate in place but restrict its linear movement to the vertical direction. The dispenser has two braking devices, a braking bar underneath the roll of bags and a pair of fingers that are at ached to the channels to engage the core. The braking bar is positioned transversely to the series of bags so that it supports them. The pair of fingers does not engage the core until the number of bags on the core has decreased and the core has begun to descend. The two braking devices work in combination to retard the rotation and dispensing of the bags and thus to apply a tension to the series of bags. Attached to the frame is a separator with, preferably, a symmetric projection on its end. The projection will engage the slot regardless of whether the bags are drawn over or under the projection. Additionally, the separator is preferably coiled in its midsection to function as a spring. As the user pulls on the bags, a tension is created by the braking devices and the user to deflect the separator which remains deflected until the projection engages the slot. Thus, when the separator engages the slot, the separator recoils through its normal position to facilitate the separation of the two bags.

Title: A composite percussive tool
Inventor: BURNETT JOHN A
IPC: B25G1/01
Filed: 1995-04-03
Abstract: A composite split head percussive tool (10) including a rigid load bearing framework (12) which carries a non-load bearing head assembly (20). The non-load bearing head assembly (20) comprises a pair of axially aligned split heads (22, 24) that are interconnected to each other by an elastomeric link (26). The elastomeric link (26) is encased and fixed within the tool body (12). During use of the tool (10), the elastomeric link acts as a dampener that suppresses the struck end rebound of the tool (10). When one head is struck against a surface, the elastomeric link (26) allows the unstruck head to move toward the struck head and provide a secondary blow that inhibits the tool's struck end from bouncing away from the surface thereby providing the hammer (10) with a unique "dead-blow" characteristic.
