Title: Rotating cylinder-throwing power electrode
Inventor: KADIJA IGOR VELJKO
IPC: G01N5/00
Filed: 1993-04-30
Granted: 1998-02-10
Abstract: This invention pertains to an apparatus and method for measuring throwing power of electroplating solutions. The apparatus is easy to use and gives reproducible measurements.  The apparatus emulates the performance of a conventional Haring Blum cell. The major disadvantage of the standard Haring Blum cell is its limited aility to vary the solution mass transport, thus limiting its applicability to very low current density applications. Furthermore, even under low-mass transport conditions, non-uniform solution distribution is experienced leading to erroneous interpretation. This invention permits the study of throwing power of electroplating solutions under a whole variety of solution agitation. The invention embodies an instrument for and a method of measuring the throwing power of electrolytes. The instrument is in a form of an elongated cylindrical body adapted for rotation about its longitudinal axis and includes a fixed conductive anode element and at least two cathode elements, at least one of which is variably spaced from the anode element. Preferably, one cathode element is fixed relative to theanode element a first predetermined distance and another cathode element is spaced from the anode element a second variable distance which is a multiple of the first distance.  The instrument also includes means for providing current to the anodeelement and equi-potentially to each of the cathode elements. The measuring includes providing each of the cathode elements with a pre-weighed removable metal foil, rotating the instrument which the anode and cathode elements are completely submerged in an electrolyte, applying current to the anode and the cathode elements, removing the metal foils from the cathode elements and weighing the metal foils with the deposit thereon to compare the weight of deposited metal at different cathode element positions.

Patent CA-2103615-C (CA)
Inventor: LEE RON C
IPC: B01J4/00
Filed: 1993-08-09
Granted: 1996-11-05
Abstract: A liquid cryogen is supplied, preferably by means of a reservoir, to a dispensing tube so that the liquid cryogen tends to flow from the dispensing tube. A heating coil wrapped around the dispensing tube heats the dispensing tube so that the liquid cryogen undergoes nucleate boiling within the dispensing tube to form a vapor block, and thereby at least impede the liquid cryogen from flowing from the dispensing tube. Flow is reestablished within the dispensing tube by terminating the heating of the dispensing tube, eg. by turning off electrical power supplied to the heating coil. The heating of the dispensing tube can be sufficient to stop the flow of liquid cryogen. Additionally, the dispensing tube can be cyclically heated by a timing circuit connected to the heating coil. Such cyclical heating is used to throttle the flow of the liquid cryogen from the dispensing tube.

Title: Self-lubricating implantable articulation member
Inventor: CALDARISE SALVATORE
IPC: A61F2/32
Filed: 1995-02-16
Granted: 2005-09-20
Abstract: Implantable articles, such as bone prostheses, are prepared by casting techniques and have incorporated therein fluid communicating passageways. The internal fluid communicating passageways convey synovial fluid from a joint space to the articulation surface of an artificial joint. The presence of synovial fluid at the articulation surface provides sufficient lubricity to the joint and enables artificial joints to utilize metal/metal, metal/ceramic, and ceramic/ceramic articulation couples without the need for a low friction polymeric lining material. Accordingly, artificial joint components formed according to the present invention are less likely to develop wear debris. The implantable articles are formed by a casting process from casting molds that are prepared using a three dimensional printing technique.
