Abstract: A barrier accessory device for a watercraft includes: an accessory connection base configured for having at least one accessory removably connected thereto; a first rail connector connected to the accessory connection base at a first end portion thereof, the first rail connector having a slot-engaging member configured to be inserted into a slot defined in one of an upper rail and a lower rail of a barrier structure of the watercraft; and a second rail connector connected to the accessory connection base at a second end portion thereof opposite the first end portion, the second rail connector having a locking assembly configured to be selectively locked onto an other one of the upper rail and the lower rail.

Abstract: A board holder for storing a marine board includes: a body extending in a length direction, the body having a board support for receiving and supporting a first lateral side of the marine board; a first strap fixed to the body at or near the board support; a first fastener adjustably fixed to the first strap; a second strap fixed to the body at: a first location spaced from the board support in the length direction; and a second location disposed between the first location and the board support; and a second fastener freely movable along the second strap, the second fastener being configured to be complementarily mated with the first fastener. When the fasteners are mated with one another, the second strap is positioned to at least partly wrap about the second lateral side of the marine board to secure the marine board in place on the board holder.

Abstract: A tow attachment for a watercraft is disclosed. The tow attachment is configured to attach a tow rope to the watercraft, and has a first part and a second part that is connected to the first part by a connecting portion. The first part is configured for rigid connection to the watercraft, and the second part is configured to attach to the tow rope. The second part disconnects from the first part about the connecting portion in response to the tow rope applying a load above a predetermined load to the second part. A tow pylon assembly having a tow pylon and the tow attachment connected to the tow pylon is also disclosed. A watercraft with the tow attachment and a watercraft with the tow pylon assembly are also disclosed.

Abstract: An apparatus and method for regenerating ion samples for a mass spectrometer are provided. Source samples are loaded on a support which is heated by a laser beam, desorbing the sample without ionization. The desorbed sample is carried by a carrier gas flow through a transfer tube, at the output of which it is ionized by corona discharge or photo-ionization. The obtained ionized sample may be analyzed in a mass spectrometer or used to serve any other appropriate purpose.

Abstract: The present invention relates to compositions and methods for reducing the concentration of noxious substances in gases and smoke. Filters comprising plant extracts, such as parenchyma tissue extract and mesophyll cell extract, are also provided, as well as methods for making same.

Abstract: The metastable atom bombardment source provides a charged particle free beam of metastable species that can be used to bombard and ionize organic and inorganic substances in a gas phase. The metastable atoms are produced by inducing a discharge in a gas (rare gases or small molecules). The discharge is curved between the cathode and anode, with the cathode located in a medium pressure zone and the anode located off-axis in a low pressure zone; A nozzle located between the cathode and the anode provides a collimated beam of metastable atoms of low kinetic energy that is directed at an ion volume containing the substances to be analyzed.
