摘要： A single blade ice skate is disclosed wherein the ice engaging blade, the toe boot plate and the heel boot plate are formed as a unitary assembly from a flat sheet of metal stock material, with the two boot plates being attached to the blade by way of twisted metal extension portions. In the initial flat state, the blade portion, the two extension portions and the two boot plates occupy a common physical plane. The two extension portions that connect the boot plates to the blade are then twisted 90.degree. in this common plane, and in a manner to place the two boot plates in planes that are normal to the plane of the blade and normal to the common plane of the initial metal stock material. The two boot plates are then bent into a U-shape, so as to provide a U-shaped vertical spring member for each of the boot plates, the spring member acting between the two boot plates and the blade (i.e. a spring member operating in the vertical plane of the blade), while at the same time providing a rigid lateral connection between the plane of the two boot plates and the plane of the blade, thereby rigidly maintaining these planes as normal planes during a skating maneuver.

摘要： A method and inlet control system for controlling a gas flow sample to an evacuated chamber such as found in a mass spectrometer, is disclosed. The system utilizes a short inlet passage having an effective opening determined by a tapered diamond or steel tip needle adjacent to the inlet passage. The needle is positionally adjusted with respect to the inlet passage by being mounted on a piezoelectric crystal which is flexed by coupling thereto an electric potential derived by sensing the ions at the ionization chamber of a mass spectrometer, for example, and developing therefrom an electric signal indicative of the total pressure within the ionization chamber. The signal coupled to the piezoelectric crystal is preferably a pulse-width modulated signal with the needle maintaining the inlet passage closed except during the time that the piezoelectric crystal is flexed due to a received pulse. A vacuum pump, and a quadrupole filter, both of which are relatively small, are also disclosed, so that a mass spectrometer system, for example, is sufficiently compact so as to be useful, in conjunction with a respiratory valve, for the analysis of respiratory gases. The method for controlling a gas sample flow to a mass spectrometer, for example, comprises providing an inlet for a gas sample into the ionization chamber of the mass spectrometer, monitoring the pressure within the ionization chamber and developing an electrical signal indicative thereof, and utilizing the developed electrical signal to control the flow of gas sample through the inlet to maintain a substantially constant pressure within the ionization chamber.
