Abstract: A hand held tool for crimping a stent onto a balloon of a catheter is disclosed. The stent crimping tool is operated in one hand by squeezing two plates together while simultaneously displacing the plates linearly to crimp and roll the stent held between the plates. Specifically, the crimping tool includes a base plate with two bosses through which respective pins pass linking the base plate to a compression plate. The compression plate has elongated diameter openings at opposite sides thereof to receive the pins. With the elongated diameter openings, the compression plate can pivot at the pins and translate linearly relative to those pins thus enabling the rolling action during the crimping process. A compression profile pad and a tapered profile pad are attached to the crimping areas of the plates to grip and together apply pressure to the uncrimped stent held therebetween. The pads may include specific contours in order to impart a desired profile to the crimped stent.

Abstract: Inexpensive communication is provided between a data base and a plurality of subscribers each equipped with only a telephone and a TV set by using only tone signals to communicate from the subscribers to the data base, and data signals at least partially to communicate from the data base to the subscribers. For this purpose, each subscriber location needs to be provided with only the demodulator portion of a modem, and the base location needs to be provided only with the modulator portion of a modem and a tone decoder. A microprocessor-controlled security device is disclosed for remotely disabling a subscriber's module in case of misuse.

Abstract: An aqueous sizing composition having a cationic lubricant, amide compound, and cationic silicone polymer aqueous emulsion which is used to produce wet chopped sized glass fiber strands or which also has a film former to produce continuous glass fiber strands. The moisture content of the wet chopped glass fiber strands is controlled to within about 9 to about 20 weight percent. The sized wet chopped glass fiber strands have good flowability and when used to produce non-woven glass fiber strand mat, produces mat with good flexibility and tensile strength.

Abstract: An aqueous sizing composition with a cationic lubricant, amide compound, and water soluble or dispersible polyol which is used to produce wet chopped sized glass fiber strands. The sized wet or dried chopped glass fiber strands can be used to produce non-woven glass fiber strand mat, having good tensile strength, and good flexibility and reduced tendency for static generation. The wet chopped glass fiber strands also have good flowability in bulk handling apparatus.
