Abstract: A swing arm for customizing the rear wheel of a motorcycle. The swing arm of the present invention is made of a right triangular structure defining a right mounting plane, a left triangular structure defining a left mounting plane, an upper and lower spanner bars joining the forward corners of the right and left triangular structures, and a right arcuated plate joining the right upper and lower corners of the right triangular structure. The right arcuated plate comprises a right pivotal connection along a pivotal axis of the swing arm, and this right pivotal connection is connectable to the frame of the motorcycle. There is further provided a left arcuated plate connected to the upper and lower spanner bars at a distance from the left mounting plane. The left arcuated plate comprises a left pivotal connection along the pivotal axis, and this left pivotal connection is connectable to the frame of the motorcycle. The distance between the left arcuated plate and the left mounting plane is greater than a width of the drive belt driving the rear wheel of the motorcycle, such that when the swing arm of the present invention is adapted to be mounted to the frame of the motorcycle, the drive belt is mountable between the left arcuated plate and the left mounting plane. The displacement of the drive belt toward the left mounting plane provides more space inside the swing arm for installing an oversize tire on the rear wheel.

Title: Improved photoresists and method of making printing plates
Inventor: MULVEY MERLIN L
IPC: H05K3/06
Filed: 1997-06-17
Granted: 2007-09-11
Abstract: Printing plates having a photoresist layer thereon that can be exposed by a computer controller laser have improved sensitivity and do not require a photomask step. We have found photoresists that include a film forming polymer, an organo azide and a photosensitive dye that absorbs light at the frequency of the patterning laser and converts it to heat energy. The heat energy in turn elevates the temperature of the organo azide above its dissociation temperature, destroying the azide in areas exposed to the light source, and solubilizing those regions. A flood exposure with ultraviolet light hardens the unexposed resist, improving its resistance to etch solvents. Thus a flood exposure with ultraviolet light can be performed prior to or after pattern exposure, to harden the resist.

Abstract: An apparatus for detecting an object adjacent an elevator door includes a housing (47) mounted at an upper edge of a car door opening (38) and in which are mounted a plurality of short range detector pairs (50) and a plurality of long range detector pairs (53). Each short range detector pair includes a transmitter (14,25,40) for generating a relatively short range infrared beam (18,27,42) toward a path of travel (16) of an elevator door (17) across the door opening and a short range receiver (15,26,41) for detecting a reflection (31) of the beam from a facing surface (17b) of the door and generating a short range beam detection signal. Each long range detector pair is positioned adjacent an associated one of the short range detector pairs and includes a transmitter (19,28,43) for generating a relatively long range infrared beam (21,30,45) across the path of travel and a receiver (20,29,44) for detecting a reflection (23) of the beam from an object (22) near the door opening and generating a long range beam detection signal. A control (11) is connected to each detector pair for turning on the transmitters and for reopening the closing door in response to the long range beam detection signal. The control responds to each short range detection signal during closing of the door to disable the associated long range transmitter and responds to termination of the short range detection signal during opening of the door to enable the associated long range transmitter to prevent detection of the moving door by the long range receivers from reopening the door.

Title: Electric radiation source and irradiation system with this radiation source
Inventor: MUCKE JENS
IPC: H01J65/00
Filed: 1997-09-08
Granted: 2005-08-16
Abstract: A radiation source (36), in particular a discharge lamp suitable for operating a dielectrically hindered pulsed discharge by means of a ballast (37), has of least one electrode (41a, 41b) separated by dielectric material (40a, 40b) from the inside of the discharge vessel. By appropriately designing at least one of the electrodes (39) and/or the dielectric material (40a, 40b), local field reinforcement areas are created, so that during the pulsed mode of operation one or more dielectrically hindered individual discharges are generated exclusively in these areas, maximum one individual discharge being generated in each area. These areas are obtained in particular by shortening the spacing in locally limited areas, for example by providing on one of the electrodes hemispherical projections (42a, 42b-44a, 44b) which extend towards the counter-electrode. This measure achieves a time-stable discharge structure with a high useful radiation effectiveness uniformly distributed throughout the discharge vessel (38).
