Title: Engine ignition and control system
Inventor: NOBLE GARDINER A
IPC: F02P3/04
Filed: 1994-11-01
Abstract: An engine ignition and control system for an internal combustion engine. The system includes an ignition transformer mounted directly to a spark plug and adapted to rapidly re-fire the spark plug during a combustion cycle enabling the performance of various ignition diagnostic procedures. A controller provides signals to a circuit which causes charging of the transformer for ignition and subsequent charging of the transformer for diagnostic purposes. The system also includes a diagnostic circuit, connected to the transformer, which can detect the occurrence of electrical discharges across the spark plug electrodes as a result of the diagnostic charges. The detection circuit either outputs a signal ar omits a signal to the controller which allows the controller to diagnose conditions within the combustion cylinder. Additionally, the diagnostic circuit is capable of outputting a signal which can be correlated to the load on the engine.

Title: Vibratory compressor-actuator
Inventor: VAN NAMEN FREDERICK T
IPC: H02K33/06
Filed: 1993-06-25
Abstract: A vibratory compressor-actuator is disclosed for generating a high pressure acoustic waveform within a chamber (14) containing a working medium (15). The compressor-actuator comprises an actuator body (H1) solidly mounted to the chamber (14) with a vibrating armature (C2) spring-mounted within. The chamber (14) and actuator body (H1) are resiliently mounted so as to be vibratable. Owing to reaction forces, vibration of the armature (C2) causes vibration of the chamber (14) which generates an acoustic waveform in the medium (15). By matching the resonant frequency of the armature (C2) to the acoustic resonant frequency of the chamber (14) and driving the armature (C2) at that frequency, extremely high pressure within the chamber (14) may be obtained.

Title: Method of and apparatus for controlling turbulence in boundary layer and other wall-bounded fluid flow fields
Inventor: SIROVICH LAWRENCE
IPC: B64C21/10
Filed: 1995-05-31
Abstract: Turbulence is controlled in boundary layer or wall-bounded fluid flow fields having a turbulent wall region characterized by a system of roll pairs extending in the direction of flow, and obliquely propagating structures interacting with the system of roll pairs, by locally introducing into the turbulent wall region two separate disturbances that are effective to produce, in a local region, a composite disturbance field that is strongly coupled to and modifies the obliquely propagating structures in a manner that increases or decreases the interaction of the propagating structures with the system of roll pairs thereby locally increasing or decreasing the turbulence in the flow field.  One of the disturbances may result from the interaction of the fluid with a linear strip, or an array of strips, of delta-shaped protrusions positioned spanwise on the wall (i.e., transverse to the flow direction); and the second disturbance may result from injecting sonic energy into the local region.   Furthermore, a linear strip or an array  of  airfoil  shaped  protrusions can be  used  for producing a pair of counter rotating rolls for controlling turbulence in the boundary layer.

Title: Adaptive power cycling for a cordless telephone
Inventor: BARTLETT RICHARD ANDREW
IPC: H04M1/73
Filed: 1995-10-12
Abstract: A cordless telephone provides for improved conservation of battery power in a handset unit when this unit is located remote from an associated base unit and in a standby state for a prolonged period of time. While the handset unit is in the standby state for less than a predetermined time period, this unit resides in a low-power monitoring mode which includes deactivating certain internal circuitryand reducing by a first time period the on-time state of other internal circuitry for conserving battery power. After being in the standby state for greater than the predetermined time period, the handset unit continues to reside in the low-powermonitoring mode, but further reduces by a second time period the on-time state of the other internal circuitry for greater conservation of battery power. Communications between the handset unit and the base unit is easily reestablished by either one of these units irrespective of the time that the handset unit has been in the standby state.

IPC: A61M15/06
Filed: 1994-07-25
Abstract: The invention concerns an inhaler device (1) having a hollow tubular member (2, 102, 402) connected to a chamber (5, 105, 405). The tubular member has a first opening (3, 103, 203) at one end through which air can be sucked and the chamber (5, 105, 405) has a hole (4, 104, 204) therein for entry of air.

To maintain or increase the swirling effect of the air a single restriction (10, 110) is arranged between the opening and the hole (4, 104, 204). A powdered substance (8) within the chamber is picked up by the swirling air within the chamber and is uniformly and finely divided by the swirling effect of the air. The effect can be enhanced by adding a movable element (6) such as a ball inside the chamber (5) and/or by providing a central core element (112, 412) inside the chamber.

Title: Inhibiting anaerobic production of volatile fatty acids and hydrogen by bacteria
Inventor: GURIJALA KOTESWARA RAO
IPC: D21H21/04
Filed: 1996-02-01
Abstract: A method for anticipating and for inhibiting the production and ac-cumulation of metabolic products by hydrolytic-fermentative bacteria in an environment. The method has the steps of monitoring for the presence of hydrogen or acetate in an environment and adding a biocide or a non-biocidal electron acceptor to the environment to inhibit bacteria growth and the subsequent production of and the accumulation of bacterial metabolic products in the environment. The method is particularly well suited for inhibiting bacteria growth in a paper mill to prevent the accumu-lation of hydrolytic-fermentative bacteria by-products, especially volatile fatty acids and hydrogen, in paper mill process water and paper product.
