Patent AU-737266-B2 (AU)
Title: Positive flow valve
Inventor: LOPEZ GEORGE A
IPC: A61M39/26
Filed: 1997-12-15
Granted: 2001-08-16
Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip. The fluid space within the valve automatically and reversibly increases upon insertion of the medical implement into the cavity and decreases upon withdrawal of the medical implement, such that a positive flow from the valve toward the catheter tip is effected upon withdrawal of the medical implement, thereby preventing a flow of blood from a patient into the catheter when the medical implement is removed from the valve.

Title: Single channel auditory stimulation system
Inventor: HOCHMAIR I HOCHMAIR E S
IPC: A61F11/04
Filed: 1982-09-17
Granted: 1987-01-15
Abstract: Chronic auditory stimulation is achieved by establishing an electric field at the base of the cochlea whereby full speech patterns are imparted to a patient. Penetration of the cochlea is not required thereby reducing the risks in installing the implanted electrodes. In a preferred embodiment the electrodes are disc shaped with the ground electrode being larger than the active electrode. The active electrode is preferably placed in the round window at the base of the cochlea or on the promontory. The ground electrode is placed 2-10 mm from the active electrode to thereby confine the electric field. The interconnections to the electrodes are tissue compatible insulation covered wires thereby minimizing stimulation of cutaneous nerve fibers.

Title: Washing column
Inventor: MALEN BERNARDUS GODEFRIDUS MAR
IPC: B01D33/00
Filed: 1982-12-14
Granted: 1984-08-02
Abstract: A washing column for the continuous separation between a solid chemical formed in a liquid multi-component system, on the one hand, and the mother liquor in which the solid chemical is suspended, on the other. In a cylindrical working space a stationary, straight, plane washing front is maintained in a packed bed of the solid chemical substance between the mother liquor, on the one hand, and a melt of the solid chemical, on the other. According to the invention, the washing column is double-walled to form an enveloping space, which contains a heat insulating medium and can be pressurized to conform to the pressure within the column. This construction permits the use of a relatively thin, glass inner wall of uniform wall thickness and inner surface. This renders the column resistant to corrosive chemicals, reduces the effect of heat exchange with the surroundings, and prevents instabilities in the washing front.

Title: Hollow towing ball for tow frame - with profiled push-fit holes through ball for fitting on shaft
IPC: B60D1/06
Filed: 1972-03-07
Abstract: The hollow, metal towing ball has upper and lower holes to fit over the vertical mounting shaft fitted to the towing frame.

The upper hole has a simple, straight edged profile with a space between the joining faces, of the shaft and the ball, being filled with a plug of adhesive. This eliminates welding the ball onto the shaft, a process which can lead to thermal distortion of the assembly.

Granted: 2001-12-25
Abstract: A method of coding a speech signal is described. In accordance with the method, a plurality of sets of indexed parameters are generated based on samples of the speech signal. Each set of indexed parameters corresponds to a waveform characterizing the speech signal at a discrete point in time. Parameters of the plurality of sets are grouped based on index value to form a first set of signals which represents the evolution of characterizing waveform shape; the signals of the first set are filtered to remove low frequency components and thereby produce a second set of signals which represents relatively high rates of evolution of characterizing waveform shape. The speech signal is then coded based on the second set of signals representing high rates of characterizing waveform shape evolution. Coding of the speech signal may further be based on a set of smoothed first signals. <IMAGE>
