Title: Trocar catheter for drainage
Inventor: COHEN HERBERT
IPC: A61B17/34
Filed: 1994-05-11
Granted: 1998-01-08
Abstract: A trocar catheter includes a trocar rod having a stepped diameter distal end for use with a catheter having a stepped diameter lumen wherein the trocar is inserted into the lumen of the catheter and the trocar is used to incise a patient and install the catheter after which the trocar is removed from the lumen of the catheter. The distal end of the trocar rod is provided with a stepped coaxial bore into which a piercing point rod, a spring and a safety sleeve are assembled. The piercing point rod has a proximal small diameter portion which is press fit into a correspondingly small diameter portion of the coaxial bore in the distal end of the trocar rod. The spring is carried on the small diameter portion of the piercing point rod and biases the safety sleeve in a distal direction. The distal end of the piercing point rod has a larger diameter portion tapering to a piercing tip and the safety sleeve has a stepped inner diameter which prevents it from moving beyond a predetermined distal position covering the piercing tip. The stepped coaxial bore has a large diameter portion for receiving the safety sleeve when it is pressed proximally against the spring. A protrusion on the distal outer surface of the safety sleeve prevents the catheter from accidentally slipping off the trocar.

Title: Retracted needle auto-injector for e.g. intra-ruminal injection
Inventor: CHRISTENSEN TERRENCE B
IPC: A61M5/20
Filed: 1982-09-13
Granted: 1986-01-30
Abstract: An injection device particularly suitable for the intraruminal injection of ruminants is described. The injection device is characterized by a needle carrying means and a needle actuation means, which are operatively coupled such that the needle actuation means permits movement of the needle carrying means from a retracted position to an extended position, wherein the needle is capable of piercing the rumen, only when the needle carrying means is in a preferred orientation (e.g. perpendicular) to the surface of the host animal at the injection site. The injection device is further characterized by a dose delivery actuation means which is responsive to the relative position of the needle carrying means and the needle actuation means such that the dose is delivered to the host animal only when the needle carrying means and the needle actuation means are in a preferred position relative to each other. The characteristic features of the described injection device substantially prevent the application of a dose to a host animal not within an intended dose delivery area.

Title: Electric motor rotor bearing construction - has ball or roller bearings for motor of variable length
IPC: H02K5/173
Filed: 1972-06-29
Abstract: A rotor bearing construction with ball or roller bearings for electric motors of variable length. The motor shaft (3) is held by two bearings (8, 9) one at the rear and one at the front or coupling end of the motor.

Patent JP-H0416231-B2 (JP)
IPC: C01D3/02
Filed: 1984-01-25
Abstract: Fluoride-containing wastes, arising in the aluminium industry, particularly spent cell linings from reduction cells, are digested with caustic soda for conversion of sodium cryolite to NaF. By use of very strong caustic soda NaF may be left in the solid residues after removal of the residual liquor and recovered from such residues by water leaching. As an alternative weaker caustic soda may be used in the digestion stage and subsequently be crystallised out from the residual liquor, after separation from the solid residues, by evaporating and/or cooling the liquor. The precipitated NaF is then conventiently redissolved in water. The NaF solution prepared by either route is then preferably subjected to electrodialysis to recover a solution of HF from it. Such HF is conveniently converted to AlF3 by reaction with alumina.
