Title: Improved purification of phenyl ester salts
Inventor: ARUMUGAM BHASKAR K
IPC: C07C69/353
Filed: 2001-06-04
Abstract: The invention relates to a process for purifying and decolorizing a phenyl ester salt. The process combines a phenyl ester salt with a solvent to form a mixture and then stirs the mixture to form a slurry. The phenyl ester salt is substantially insoluble in this solvent. The process then collects the phenyl ester salt from the slurry. The collected phenyl ester salt may then be optionally dried or recrystallized. The collected phenyl ester salt is dissolved in a solvent to form a solution. The solution is decolorized and then spray dried to form a powder of the phenyl ester salt. As a result of the process the phenyl ester salt powder has a higher purity and an improved color as compared to the starting phenyl ester salt.

Title: Control of receiver immunity to interference by controlling linearity
Inventor: HUTCHISON JAMES A
IPC: H04B1/10
Filed: 2001-08-01
Abstract: A radio receiver has a low noise amplifier. The low noise amplifier is enabled. If a predicted level of interference is expected to produce an acceptable bit error rate or other signal error measurement, the low noise amplifier is set to a "low" linearity level. If the predicted level of interference is not expected to be acceptable, the low noise amplifier is adjusted to a "high" level of linearity. The level of linearity required is determined by checking one or more prediction criteria: the mobile station's current operating mode, the strength of a received signal, the strength of a signal transmitted by the mobile station, the current level of interference, an acceptable level of interference, and whether the low noise amplifier is enabled or bypassed. Each of the prediction criteria may not be weighted equally. The determination is repeated as the prediction criteria change.

Title: Corewire securement system
Inventor: LENZ JASON T
IPC: A61M25/00
Filed: 2001-10-02
Abstract: A catheter for use in vasculature or other lumen within body structures includes a shaft formed from an elongated polymeric flexible tube. A metallic tube may be bound to the distal end of this tube. A thinner, more flexible tube may be attached to the distal end of a metallic tube. The two plastic tubes, together with any metallic tube define a lumen for providing communication with an angioplasty balloon or with a body lumen at the distal end of the catheter. A catheter may include a core member to facilitate moving the catheter through a lumen, and to reduce the likelihood that the catheter will kink or bend improperly. This metallic core member extends from the hub to some point distal on the catheter, and may extend to the distal tip of the catheter. The distal end of a catheter balloon may be secured to the core member during manufacture of the catheter. The core member has a zigzagged or helix shape at the proximal end which is friction fit into the hub lumen, and may have a pointed tip that embeds in the hub inner wall. During manufacture, the core member can be secured within the hub with reduced reliance on adhesives or molding of the core member within the hub body. The core member may be secured within the hub by being press fit into the hub lumen. The catheter is more easily manufactured, and has an increased volume and reduced obstruction by adhesive in comparison with other methods of securing the core member.

Title: Method for ion-exchange purification of copper-containing waste waters from galvanic manufacture
Inventor: DOBREVSKI IVAN D
IPC: C02F1/42
Filed: 1988-02-19
Abstract: Purified water meeting the standards for re-circulation water supply is obtained by this method, while carrying out an efficient and economically profitable regeneration of spent ionites. The method uses weak electrolyte ionites connected in series - a weak base anionite in OH-form and a weak acid cationite in H-form.

Title: Pedal assembly device
Inventor: JACQUES ANDRE
IPC: B62M1/36
Filed: 2000-10-19
Abstract: In order to understand the invention, it is necessary to BEGIN by understanding IN DEPTH the following DISCOVERY which relates to the calf during pedaling;  the entire world is misled by two OPTICAL ILLUSIONS (figs. 21 and 22 symbolize a lower member pressing down upon a pedal, 6 is the thigh, 11 the leg, A+B the foot and 1 is the ankle). The first ILLUSION (fig 21) is to believe that the calf (M) INCREASES the pressure on the pedal. The second ILLUSION (fig 22) is to FAIL to  see that the force M is CANCELLED OUT by the force M'. The total amount of pressure on the pedal is derived from the THIGH EXCLUSIVELY, whereby the contraction of the CALF is a loss of energy. The aim of the invention is to REPLACE the pedal by a mechanism which AVOIDS THE USE OF THE CALF, thereby enabling performance to be MULTIPLIED BY TWO WITHOUT incurring A LOSS OF POWER!

Abstract: This invention is directed to a useful improvement in a seat belt mount mechanism for use in an automotive vehicle of the type that an anchor plate adapted to support a shoulder anchor for holding the seat belt extending through an opening defined therein is mounted operatively to a door sash element of the vehicle body by way of a fixing bracket, wherein there is provided an elongated portion extending outwardly from the lower end of the anchor plate, upon which the elongated portion the shoulder anchor is held operatively, whereby it is feasible in practice to bring the mount for the shoulder anchor as far behind as possible of the door sash element, and consequently, the seat belt may serve more effectively in function to forcibly catch a driver or passengers therein.     With this arrangement, it is possible in practice to make the anchor plate and the fixing bracket small and compact in construction, accordingly.

Abstract: An elastic store memory circuit includes first and second elastic store memories.  Each of the first and second elastic store memories generates a phase comparison signal when a phase difference between a write timing and a read timing is within a predetermined phase range.  The elastic store memory circuit also includes a selector which selects either the input data read out from the first elastic store memory or the input data read out from the second elastic store memory, and a slip signal generator for generating a slip signal on the basis of a write reset timing at which the first and second elastic store memories are reset, a read reset timing at which the first and second elastic store memories are reset, and the phase comparison signal.  The slip signal indicates which one of the write reset timing and the read reset timing precedes the other one.
