Title: Sustained release lithium-containing tablets and method for their manufacture
Inventor: TRIGGER DAVID JOHN
IPC: A61K9/20
Filed: 1983-04-21
Abstract: The release pattern of sustained release lithium carbonate tablets is improved by using a particular form of lithium carbonate material. This should have acicular crystals with a substantially monomodal particle size distribution in which the curve showing volume percentages of particles of different sizes shows a peak at a particle diameter of between 10 and 25  mu m. Moreover not more than 20% by volume of the material should have a particular diameter above 30  mu m. A preferred sustained release agent is a mixture of glyceryl mono-di- and tri-esters of straight chain saturated fatty acids. The tablets may be made by a moist granulation technique, followed by screening to ensure a granulate of appropriate grain sizes, after which the granulate is compacted into tablets.

Title: Electrode for plasma arc torch
Inventor: SEVERANCE WAYNE STANLEY JR
IPC: B23K35/02
Filed: 1990-08-08
Abstract: An electrode (14) for a plasma arc torch (10) and a method of fabricating the same are disclosed, and wherein the electrode (14) includes a copper holder (16) having a lower end which mounts an emissive insert (28) which acts as the cathode terminal for the arc during operation. Where a torch (10) is used in an oxidizing atmosphere, the copper holder (16) tends to oxidize, and the arc tends to attach to the oxidized copper rather than the insert (28), which results in the rapid destruction of the holder (16). To prevent this destruction, a sleeve (32) of silver or other metal having a relatively high work function is provided, and which is positioned to surround the insert (28) and form an annular ring (35) on the lower end surface (20) of the holder and thus to surround the exposed end face of the emissive insert (28). The annular ring (35) serves to prevent arcing from the copper holder (16), and so that the arc is maintained on the insert (28).

Title: Hydrodynamic torque converter
Inventor: MIDDELMANN VOLKER
IPC: F16H61/14
Filed: 1995-02-07
Granted: 1998-09-16
Abstract: The housing of a hydrokinetic torque converter in the power train between the engine and the transmission of a motor vehicle contains a lockup valve which can be engaged to transmit torque directly from the output element of the engine to the output member of the turbine in the housing. Engagement of the lockup clutch at a relatively low RPM of the engine and/or under certain other circumstances is prevented or minimized by the provision of one or more valves which are designed to establish or to at least partially seal one or more paths for direct flow of hydraulic fluid between two compartments forming part of a chamber in the housing of the torque converter and being disposed at opposite sides of the axially movable piston of the lockup clutch. The valve or valves can be designed to react in response to changing RPM of the housing of the torque converter, in response to changes of the temperature of hydraulic fluid in the housing and/or in response to changes of the viscosity of such fluid. The valving element or elements of the valve or valves can be caused to change its or their position(s) relative to the respective path(s) in response to the action of centrifugal force and/or due to direct contact with hydraulic fluid in the housing of the torque converter.
