Abstract: A method of access validation whereby a false system becomes bound to an accessing user if an unacceptable accessing pattern is detected. The false system interacts in a mode similar to the conversational protocols of target systems, but remains logically insulated from said target systems. Concurrent messages to security monitors at binding time ensure entrapment.

Abstract: An air assisted drop-on-demand ink jet head 10 has an ink chamber with an ink drop-forming orifice outlet 23 from which ink drops are generated in response to pressure waves caused by the piezoelectric crystal 56. The ink drops are carried by air outwardly through an external orifice 24 and toward printing medium. The internal orifice outlet 23 is centered in a projecting structure 48 which extends toward the external orifice 24. In one form, the projection 48 is of a frustoconical or mesa-like shape. Air flowing past the top of the projection prevents ink from wetting anything but the top of the projection, resulting in highly uniform ink drop formation with a single uniform dot being produced on the printing medium in response to each pressure wave.

Abstract: The viscosity of thickened aqueous solutions of water­-soluble polymers is reduced by the addition of alkali metal and alkaline earth metal salts of hypochlorous acid and tertiary amines. The combination of the salt and the tertiary amine is much more efficient in speed of reduction in viscosity and in the completeness of the degradation of the polymer than the use of the metal salt alone. The process of this invention is particularly useful in fracturing of oil wells.

Abstract: A method and apparatus are disclosed for controlling a pulse width modulating (PWM) inverter controlled for ignition by a PWM pulse (E U , E V , E W ) produced with a carrier wave (g) and a modulation wave (e). The method comprises sampling an amplitude of the modulation wave (e) at a cycle rate related to the frequency of the carrier wave. The modulation wave and the carrier wave are synchronized when the sample modulation wave amplitude has a peak value (V R ) greater than an amplitude (H) of the carrier wave. The modulation wave and the carrier wave are asynchronized when the sampled modulation wave has a peak value less than the amplitude of the carrier wave.

Abstract: A quartz quadrupole comprises a quartz substrate (13), conductive strips (15) and low-conductivity strips (17). The substrate includes hyperbolic inner surfaces (19) which provide the geometry for the conformed conductive strips to produce an appropriate electric field for mass filter operation. The use of quartz as a substrate material provides the thermal and electrical characteristics required by high performance mass filtering operations, including scanning mode operation to 800 amu and above. During such operation, potential field distortions by accumulated charge in cusp sections of the substrate are minimized by the low-conductivity strips, which are arranged to overlap longitudinal edges of the conductive strips. Formation of the quartz substrate is made possible by high precision machining, grinding and polishing of a refractory metal mandrel. The actual step of forming the substrate is simplified by the low thermal coefficient of expansion of the quartz. The conductive strips are applied by firing metal-glass frit tape. The low-conductivity strips are applied by firing a metal-­oxide slurry including a bonding agent.

Abstract: A single phase induction motor starting and auto­matic reversing switch has two pairs of springy vertically spaced apart switch blades (36,37,40,41) supported in opposed cantilever fashion on an insulating base (10). Each pair consists of an upper blade (36,40) and a lower blade (37,41). A nominally stationary contact (53,54,63, 64) is mounted in spaced relation above each upper blade (36,40) and below each lower blade (37,41). Opposite ends of the motor starting winding (20) are connected in common between the upper and lower stationary contacts (53,54,63,64). A shaft (76) of insulating material with a lever (79) at one end operates the switch. The shaft (76) extends between the vertically spaced apart blade pairs (36,37 and 40,41) and has axially displaced oppo­sitely radially extending arms (77,78), one (78) between one pair of blades (36,37) and the other (77) between the other pair of blades (40,41). Turning the operator shaft (76) in a first direction causes one arm (78) to press a blade (36) against one upper stationary contact (53) and the other arm (77) to press a blade (41) against one lower contact (63). Turning the shaft (76) in a second direction causes the other blades (37,40) in each pair to contact stationary contacts (64,54) to change the current flow direction through the starting winding. A centrifu­gal force responsive device on the motor shaft actuates the switch operator.
