Abstract: A multipole ion guide which begins in one pumping stage and extends continuously into one or more subsequent pumping stages has been incorporated into an atmospheric pressure ion source mass spectrometer system. Ions delivered into vacuum from an electrospray, atmospheric pressure chemical ionization or inductively coupled plasma ion source are guided and focused into a mass analyzer with high efficiency using the multipole ion guide. The background pressure over a portion of the multipole ion guide length is high enough to cause kinetic energy cooling of ions traversing the ion guide length due to ion collisions with neutral background gas molecules. This ion kinetic energy cooling lowers energy spread of ions traversing the multipole ion guide length. The multipole ion guide DC offset potential can be used to adjust the mean ion energy and the ion guide a and q values can be set to reduce or expand the range of ion mass to charge which will be transmitted through the ion guide. These features of multipole ion guides and multiple pumping stage multipole ion guides are used to improve performance and lower the cost of atmospheric pressure ion source mass spectrometer instruments.

Abstract: Seismic exploration for hydrocarbons may use an eccentric-mass (or "swinging-weight") vibrator as the seismic source. According to the invention, a vibrator undergoes alternate periods of acceleration and deceleration, during one of which the vibration may be annulled. For example, the rotating mass may be formed in a plurality of parts; then the several parts are disposed in a manner that rapidly and automatically balances their vibratory forces during the period when the vibration is to be annulled, and that adds their vibratory forces during the other period.The invention further provides for modulation of the frequency-time relation during deceleration, for synchronization of several vibrators, and for modulation of the effective output force by controllable variation of the mass, eccentric radius or relative phase of the several parts of the rotating mass; in such modulation, only resultant forces are applied to the vibrator bearings.

Title: Harvester with hydraulically driven, flow-compensated rotary cutter bed
Inventor: O'HALLORAN MICHAEL L
IPC: A01D34/80
Filed: 1994-05-20
Granted: 2000-07-18
Abstract: A crop harvester (10) is provided with a rotary type cutter bed (30) in which a series of rotary cutters (32a-32j) extend across the path of travel of the machine for rotation about individual upright axes. A hydraulic drive for the cutter bed includes a variable volume pump (210) driven by the output shaft of an engine (208) associated with the harvester. The operating circuit of the hydraulic drive pumps oil through the circuit at a certain rate of flow, depending upon the engine speed and the position of a swash plate (260) within the pump. A control circuit communicating with the operating circuit (228) is capable of sensing load in the operating circuit tending to lug down and reduce the speed of the engine (208), which would normally reduce the flow rate and hence the cutter speed. However, in response to detecting such increased load, the control circuit compensates by adjusting the position of the swash plate (260) so as to correspondingly pump more oil at the lower engine speed, thus maintaining the cutter speed essentially constant.

Title: Hydrogenation of substrate and products manufactured according to the process
Inventor: HARROD MAGNUS
IPC: C07C29/149
Filed: 1995-07-03
Granted: 2005-10-18
Abstract: A typical traditional reactor for hydrogenation consists of a tank filled with a liquid and a gas and a small particle catalyst. The reaction is carried out at high pressures and high temperatures. Lack of gas on the catalyst surface limits the velocity of reaction. Much work has been done to increase the quantity of gas on the catalyst. It has not been possible to solve this problem effectively with the techniques of today. According to the invention an extra solvent is added to the reaction mixture. By bringing the whole mixture (solvent, substrate; hydrogen and reaction products) to super-critical or near-critical state, a substantially homogeneous mixture can be obtained. By this method it is possible to control the concentration of gas on the catalyst to the desired level. The velocity of reaction is thereby increased considerably. The hydrogenation reactions principally involved comprise hydrogenation of carbon-carbon double bonds (C = C) in lipids; hydrogenation of COOR to C-OH and HO-R to produce fatty alcohols; and direct hydrogenation of oxygen to hydrogen peroxide.
