Title: Process for producing saturated aliphatic carboxylic acid amide
Inventor: AIZAWA TOSHIYUKI
IPC: C07C233/05
Filed: 1997-11-28
Abstract: A process for producing a saturated aliphatic carboxylic acid amide, comprising reacting a saturated aliphatic carboxylic acid with ammonia to thereby obtain a saturated aliphatic ammonium carboxylate and subjecting the saturated aliphatic ammonium carboxylate to a dehydration reaction for obtaining a saturated aliphatic carboxylic acid amide, wherein the dehydration reaction of the saturated aliphatic ammonium carboxylate is conducted while supplying water to a reaction system in which the dehydration reaction is carried out.  Preferably, water is continuously supplied to the reaction system so that the production of the saturated aliphatic carboxylic acid amide is carried out in a continuous manner and the amount of water present in a steady state ranges from 20 to 70 mol per 100 mol of a total of the saturated aliphatic carboxylic acid, the ammonia, the saturated aliphatic ammonium carboxylate, the saturated aliphatic carboxylic acid amide and the water.  This process enables simplification of the production steps, ensures high operation efficiency, lowers production facility constructing and operating costs, reduces the amount of by-products and enables producing a high-purity carboxylic acid amide at a high selectivity, at a high yield and on an industrial scale.

Patent CA-2225665-A1 (CA)
Inventor: LAPLANTE PATRICK R
IPC: G10D13/02
Filed: 1995-06-26
Abstract: A hydraulic system for applying tension to musical drum heads (2). It consists of one or more master cylinders (166) applying pressure to a hydraulic fluid (106) in a sealed circuit. The master cylinders (166) may be hand-activated, foot-activated, controlled by an external source (167), or a combination thereof. The hydraulic fluid is then forced through tubing (32) to any number of reacting slave cylinders (50). The slave cylinders may be either single action (one moving piston and seal) or dual action (two moving pistons and seals moving in opposite directions), depending on the size and configuration of the drum (2). The pistons (50) activate a mechanical lever (68) or combination linkage that in turn pulls on a typical tension screw (10) and rim (4) configuration found on most common musical drums. The system allows for immediate pitch changes through the complete range of the drum while always maintaining uniform tension around the perimeter of each head. It also allows a fixed preset ratio between the tensions of the top and bottom heads on a twoheaded drum. The system includes a procedure for rapid change of heads with immediate tension balancing. With the addition of a visual gauge to observe and repeat the fluid pressure in the hydraulic system, accurate pitches can be recalled no matter what source initiated the change.

Title: Medical valve with fluid escape space
Inventor: LOPEZ GEORGE A
IPC: A61M39/10
Filed: 1996-12-16
Abstract: A medical valve has a body which includes a wall structure defining an internal cavity hav-ing an inside and an outside. The body also has a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the deliv-ery end. The body has a fluid escape space in its wall struc-ture.   The valve also has a spike with a tip and at least one hole located at or near the tip. The spike has a passageway in com-munication with the hole that al-lows fluid to flow through the spike. A resilient seal in the cav-ity surrounds the spike. This seal is adapted to be moved into a compressed state upon insertion of the tip of the medical imple-ment into the opening. The seal is sufficiently resilient to return to a decompressed state upon re-moval of the tip of the medical implement from the opening. The fluid escape space is in fluid communication with the outside of the cavity when the seal is in its compressed state.

Inventor: HATAMI-HANZA HAMID
IPC: H01S5/50
Filed: 1998-08-26
Abstract: A high gain, high output power, low noise optical amplifier is provided using passive and active optical waveguides and devices. The amplifier consists of one or more optical laser pump (s), optical gain module in the form of a four port Mach-Zehnder interferometer with two active waveguide arms, and means for controlling and monitoring the amplifier parameters. This configuration provides a both directional pumping while achieving twice as high gain and output power than any other optical fiber configuration with the same amount of pump energy with only half of the noise generated in the active media mixed with the amplified signal. Using the optical gain module provided in this invention, the optical signal first split into two branches and amplify by the active waveguide and recombine constructively and exit at the output port of the Mach-Zehnder interferometer. The power of the two split and amplified signals are added together constructively because of 100% phase correlation while half of the noise generated in the two active arms, having random phase relative to each other, filter out from the amplified signal based on the principle operation of Mach-Zehnder interferometers. This results in achieving an optical amplifier with ideally 3 dB higher gain, 3 dB higher output power, and 3 dB  less noise figure than any other optical amplifier with the same amount of pump energy. The noise figure of an optical amplifier built based on the principle of present invention ideally approaches 0 dB.

Abstract: A means and method of photonic heterodyning wherein at least one photonic beam s et (10, 11) having fundamental frequencies to be heterodyned is used to produce a dynamic interference image that is projecte d onto an image component separator (15). Energy from selected portions of the dynamic image is separated into at least one output (20 , 21). Energy components within the dynamic image move relative to the separating locations as determined by the fundamental input freq uencies. This causes intermodulation of the input signals and the development of energy at the sideband frequencies in the output(s). Spec ial interference is also used to provide amplified photonic heterodyning.

Abstract: A frame for a tillage implement includes a pair of opposing frame sections pivotally connected to a central kingpost for a folding movement between a transversely extending working position and a longitudinally extending transport position.  The frame sections have mounted thereto a number of tool sub-frames carrying ground engaging working tools. The tool sub-frames are pivotally movable relative to a rockshaft carried by the frame sections so as to be rotatable between a lowered operative position and a generally vertical raised non-working position. Depth control for the ground engaging tools is accomplished through the rotation of the rockshaft about its pivot lug. The frame sections are connected at the inner end to the kingpost so that the main frame members abut when placed in the working position. Each frame member is supported by a pair of wheel assemblies at the inner and distal ends respectively. The inner wheel assemblies of each frame section is steered by a link connecting the wheel spindle to the hitch member to control the orientation thereof.
