Title: Snap-on bumper for air spring
Inventor: HILBURGER MARK D
IPC: F16F9/05
Filed: 1999-06-28
Granted: 2007-11-20
Abstract: An air spring has a pair of spaced end members for mounting the spring at spaced locations on a structure. A flexible sleeve of elastomeric material is sealingly engaged with the end members and forms a pressurized fluid chamber therebetween. A post is mounted on one of the end members and extends into the fluid chamber. A shock absorbing two-piece bumper includes a rigid base which is formed with an axial opening and is seated upon one of the end members with the post extending into the opening. An elastomeric member is mounted within the axial opening of the rigid base member and is snap-fitted onto the post. The upper end of the elastomeric member extends outwardly over the upper end of the base to engage the opposite end member upon the air spring failing or experiencing a large deflection. The two-piece bumper provides a high load carrying capability with low deflection and replaces the heretofore used single member elastomeric bumper.

Title: Artificial sensibility
Inventor: LUNDBORG GOERAN
IPC: A61F2/72
Filed: 1998-04-29
Granted: 2008-10-07
Abstract: Loss or absence of sensibility in the hand, foot or other part of the body can constitute a severe handicap after injury or in disease. Also when hand prostheses are used following amputation, injuries lack of sensibility in the prostheses constitutes a major problem. The prevailing invention refers to a new principle for artificial sensibility by sense substitution (replacement of a lost sense function by utilization of an alternate sense). The primary aim is to, by using the hearing sense, achieve sensibility in hand prostheses or hands which have lost their sensibility by injury or disease. According to this principle vibrotactile stimuli to the fingers are registrated by sensors of microphone type, placed at finger level, the signals being processed and transformated into acoustic stimuli. By using this principle the patient can "feel with the hearing sense" hereby utilizing the hearing sense to register and identify the surface, texture, density and shape of the item which is touched.

Title: Apparatus for a fluid impingement thermal cycler
Inventor: WOUDENBERG TIMOTHY M
IPC: C12M1/00
Filed: 1998-09-30
Granted: 2003-12-02
Abstract: Apparatus is disclosed that thermally cycles samples between at least two temperatures. The apparatus operates by impinging fluid jets onto the outer walls of a sample-containing region. Because the impinging fluid jets provide a high heat transfer coefficient between the jet and the sample-containing region, the sample-containing regions are uniformly cycled between the two temperatures. The heat exchange rate between the jets and the sample regions is substantially greater than in the case of laminar flow.

Granted: 2004-06-22
Abstract: A method of purifying an acid leaching solution obtained by processing hydrometallurgically material that contains valuable metals and also Fe3+ and Fe2+, and possibly also arsenic in solution. The major part of the Fe3+-content and the arsenic is precipitated out in a first stage, by adding pH-elevating agent to the leaching solution. The precipitate formed in the first precipitation stage is extracted from the solution and removed from the process. The solution is oxidised in a second precipitation stage while adding a further pH-elevating agent for oxidation of Fe2+ and precipitation of resultant Fe3+ and any arsenic still present. The resultant precipitate and any residual solid pH-elevating agent are then extracted from the solution and returned in the process to more acid conditions, and the thus purified solution is then processed to win its valuable metal content in a manner per se. The pH is suitably raised during the first stage to a value in the range of 2.2-2.8, and in the second stage to a value in the range of 3.0-4.5. The oxidising process in the second stage is suitably effected by injecting air into the solution and by preferably using lime or limestone as the pH-elevating agent. Solid material extracted from the second stage is returned beneficially to the first stage. Some of the solid material taken from each precipitation stage can be recycled within respective stages as a nucleating agent.

Abstract: A needle arrangement for an injection device (16) has a cannula carrier (10) to which a cannula (12) is secured and which is designed to be removably secured to the injection device (16). The needle arrangement has a cap (32) which can slide on the cannula carrier (10) in an approximately parallel direction to the length of the cannula (12), is provided at its proximal end section with a through hole (42) for the cannula (12) and in its proximal end position covers the cannula (12). A pressure spring (26) is arranged between the cannula carrier (10) and the cap (32) for moving the cap (32) into its proximal end position. Also provided is a covering cap (66) which encloses the sliding cap (32), the cannula (12) and the cannula carrier (10), and is closed in a sterile manner by a closure member (71) which can be removed by a user from the open side of the covering cap (66).      This needle arrangement can be easily replaced after an injection. It improves compliance because the patient never sees the cannula (12). The pressure spring can be designed as a plastic spring (26). It preferably forms a single piece with the cannula carrier (10), thus simplifying manufacture.
