Title: Cigarette system
Inventor: KACZMAREK PETER P
IPC: A24D1/00
Filed: 1992-10-29
Granted: 1998-04-07
Abstract: 28 A novel non-self-extinguishing factory-made cigarette is described which has a free burn rate of no more than about 4 mm/min., preferably no more than about 3.5 mm/min. This free burn rate permits the provision of a cigarette having a greater number of puffs, at least about 2 more, preferably at least about 4 more and more preferably at least about 6 more, than a conventional cigarette of same dimensions and length of tobacco rod. The cigarettes may be partially smoked, extinguished, stored and then resmoked. The free burn rate and greater-than-normal number of puffs may be achieved by employing a slower burning tobacco blend, a lower draw resistance tobacco, a greater tobacco density and/or a burn rate retardant wrapper.

Title: Golf ball dimple configuration method and product
Inventor: STIEFEL JOSEPH F
IPC: A63B37/00
Filed: 1996-03-29
Granted: 2001-12-25
Abstract: A dimple configuration for the surface of a golf ball is provided by selecting a fixed number of dimples, placing said dimples on a computer model of the ball in random, helter-skelter locations on one selected section without regard to the other dimples present, and identifying each dimple and the adjacent dimples which overlap it.  For each dimple so identified, the aggregate component of overlap in the longitudinal and latitudinal directions is computed, the center of each dimple is relocated so as to minimize over-lap, and the steps of identifying, computing, and relocating are repeated for each dimple until the aggregate overlap is reduced to a predetermined amount.  The resultant ball provides a random dimple configuration which has no repeat-ing patterns within the sections.

Title: Electrospray and atmospheric pressure chemical ionization sources
Inventor: WHITEHOUSE CRAIG
IPC: G01N27/62
Filed: 1995-03-07
Granted: 2004-01-20
Abstract: Improvements have been made to the Electrospray and Atmospheric Pressure Chemical Ionization source chambers interfaced to mass spectrometers to simplify source performance optimization and source operation and to improve system sensitivity. The atmospheric pressure ion source procedure for optimizing performance has been simplified by adding windows along the sides of the atmospheric pressure ionization chamber allowing direct viewing of Electrospray and Atmospheric pressure ion source during operation. A cylindrical lens which extends along the side walls of atmospheric pressure chamber has been configured to be semitransparent for viewing into the chamber. This cylindrical shaped side lens is electrically isolated from the Electrospray liquid introduction needle and Electrospray chamber endplate. Improved Electrospray mass spectrometer system sensitivity can be achieved when operating the cylindrical lens with a higher potential difference between it and the Electrospray liquid introduction needle than is set between the needle and the endplate.

Title: Modem loop current detect system to detect an off-hook condition in an extension telephone
Inventor: PITSCH ROBERT ALAN
IPC: H04B10/2581
Filed: 1996-12-18
Granted: 2002-09-10
Abstract: A telephone line monitoring circuit uses an optoisolator (OPTO 2) to convert the telephone line current to a voltage which is applied to the input of an A/D converter (118). The A/D values are coarse values representing telephone line current. The A/D is sampled at a predetermined interval to identify changes introduced by the telephone company central office, and to take those changes into account when deciding if an extension telephone has gone off-hook. When a customer causes an extension telephone to go off-hook, the line current divides between the extension telephone and the IRD modem (100), and such change is detected.
