Abstract: Corrosion inhibiting particles comprise an inorganic oxide which is silica or alumina, having corrosion inhibiting cations, particularly calcium or zinc cations, chemically bound to the particles. They may be prepared by contacting a silica or alumina containing hydroxyl groups with an alkaline solution containing the cations, at ambient temperature. The corrosion inhibiting particles may be incorporated into protective coatings, e.g. paints based on epoxy resins, alkyd resins, vinyl resins or chlorinated rubbers, in amounts up to 80% wt based on dry film weight, giving coatings with up to 7.2% wt corrosion inhibiting cations. Release of the cations is by ion exchange with other cations, e.g. the alkali metal cations of sea water, and does not, as is normal with corrosion inhibiting coatings, depend on the water solubility of the corrosion inhibitor.

Granted: 1994-03-29
Abstract: ABSTRACT    A least recently used associative map is described for translating  virtual  memory  addresses  to  real  memory addresses.  The map includes a stack of storage devices each with a comparator.  The storage devices are arranged in a push down stack with an input storage device to receive the incoming virtual address and store the corresponding real address and the other storage devices coupled to the output of the previous higher  storage devices and with storage devices storing the translation of virtual address and real address in order of recent use with the  last or bottom storage  device  storing the  least  recently used  address. When the comparator detects a compare that real address is provided out and that translation is applied to the input storage device as the most recently used translation and the other translations are shifted down the stack to replace in the storage device that had the compare with the translation from the previous storage device.  If there is not a compare a new translation is entered at the input storage device and the  other translations  are  shifted down with the  least recently used being shifted out if the storage devices are full.

Title: Ski boot
Inventor: HEUVEL JOHAN G F
IPC: A43B5/04
Filed: 1990-10-29
Granted: 1999-10-05
Abstract: Human anatomy provides angular ankle movement, known as dorsi flexion and plantar flexion, far in excess of that required for modern Alpine Skiing. The musculature of the lower leg is well adapted for controlling a foot sized lever. However, when the foot is extended to ski size dimensions, muscular strength is inadequate to afford the skier proper control over his position in relation to the ski, a position commonly referred to as forward-lean.      Conventional ski boots assist the skier maintaining the correct forward-lean position by using resilient stiffeners in combination with articulated areas or hinges, to effectively reduce the importance of the lower leg muscles as part of the total skier to ski equation and replace active muscle action by static positioning means.      The ski boot according to this invention uses the principles of leverage, reducing available angular ankle movement into a lesser and more controllable angular forward-lean movement, providing muscular adaptation, optimizing forward-lean control.

Title: Filter insert formed as a pleated pack and a process for its production
Inventor: MICHAELIS UDO
IPC: F02M35/024
Filed: 1991-01-24
Granted: 1998-11-10
Abstract: A filter insert of non-woven textile fleece formed as a pleated pack is self-supporting and consists of weldable non-woven material. Each of the two longitudinal outer side edges of the pleated pack is closed by the material that forms the pleats.  Each pleat end is bent in the same direction at the side edge and lies closely on the corresponding folded edge of the next adjacent pleat end, and is welded to it.  Each pleat end extends over the folded edge of the adjacent pleat end by 1.5 to 2.5 times the separation distance between the pleats in the pack.  To manufacture the pack, the flat non-woven filter medium is first folded and then a specific separation distance is set between the pleats by pulling them apart.  The two outer longitudinal edges of the pleats are each clamped in profiled members corresponding to the geometry and the dimensions of the pleats, and being in the shape of saw tooth combs that fit and clamp into the upper and the lower sides of the pleats.  The filter material is allowed to extend beyond the profiled members on both sides of the pack by an amount from 1.5 to 2.5 times the separation distance.  The projecting material is then folded over on both sides by a pressure element until each pleat end of projecting material lies on and overlaps the next adjacent pleat end.  The energy required to effect welding is next introduced through the pressure element.  Additional and subsequent pressure elements fix the welded points during the cooling period.  The profiled members are then removed, and the pleated pack cut to length.
