Title: A method for the application of a layer remaining permanently adhesive onto the inside of a breast prosthesis
Inventor: STUFFER HANS
IPC: A61F2/52
Filed: 1999-04-21
Abstract: A method for the application of a two-component permanent silicone adhesive to a shell-shaped breast prosthesis of soft, elastic material preferably a two-component silicone rubber body provided with welded plastic film cover and cured in a heated mould. The method includes the steps of injecting the two-component adhesive through a borehole provided in the lid of the mould after the body of prosthesis is placed in the mould and the lid is closed. The adhesive layer is then cured together with the body. Alternative methods include manufacturing the adhesive layer separately and positioning the adhesive in the mould prior to moulding or inserting a reusable thermoplastic shell between the adhesive and the mould lid.

Title: Tire having improved tread portion for reducing formation of anomalies causing user dissatisfaction
Inventor: JANAJREH IBRAHIM MUSTAFA
IPC: B60C11/13
Filed: 1999-01-21
Abstract: The invention is directed to a shoulder construction of the tread area of pneumatic tires which provides increased stability and reduced wear. The shoulder construction comprises a decoupling rib having an outer surface arranged circumferentially about the tire on an outer edge of the tread portion. A shoulder rib, which also has an outer surface, is arranged inwardly of an adjacent the decoupling rib. A groove, which is defined by the inner and outer side faces of the decoupling rib and the shoulder rib, extends from its base radially beneath the outer surface of the decoupling rib first diagonally toward and then away from the central radial axis of the shoulder rib. The groove configures the inner and outer side faces of the decoupling and shoulder ribs in conforming image and forms an unsupported outer surface area on the shoulder rib. This construction, under nominal pressure and load at the foot portion, provides radial stress which is substantially equalized from an outer edge over a major portion of the outer surface of the shoulder rib and provides for a portion of the inner side surface of the decoupling rib and a portion of the outer side surface of the shoulder rib to move into mutual contact providing reduced wear and increased lateral stability of the shoulder rib.

Title: Acceleration protective suit
Inventor: REINHARD ANDREAS
IPC: A41D13/00
Filed: 1998-04-23
Abstract: The inventive suit is comprised of, together with a lining and a slipover, an active part which is arranged between the same. This active part is at least partially constructed of a layer (3) which faces the body and of a layer (4) which faces away from the same. Both layers are made of a liquid-tight, slightly stretchable textile material and are connected to one another at connection points (6) by gluing, heat sealing or by sewing. The results in the production of cavities (5). The cavities are filled with a liquid through valves (16, 17). Connecting parts which only transfer tensile stress can be arranged between areas which are comprised of the layers (3, 4), for example, upper parts (14) and frontal parts (15). This builds up a compensating pressure, said pressure being proportional to the acceleration acting in the momentary and local direction, on the body parts under the suit and thus relieves the pilot's body from the effects of such accelerations. The suit is closed by zip fasteners (11, 12, 13), is fitted to the momentary body requirements of the wearer by means of hook-and-loop fasteners and is tightened by using zip fasteners or a fluidic tightening device.

Title: Machining apparatus and method
Inventor: KLAUSER ANDREW THOMAS
IPC: B24B49/00
Filed: 1998-06-24
Abstract: A pair of grinding wheel carriages, each carrying its own grinding wheel, are both carried by a grinding machine to one side of a work carriage and workpiece when carried thereby. The workpiece is, in this instance, a camshaft with multiple pairs of similar cams disposed along the axis of the workpiece. The operation control and disposition of the grinding wheels provides for use of either grinding wheel to grind cam pairs or both grinding wheels to simultaneously grind a pair of cam pairs. The method involves first grinding a first cam pair of spaced but in phase cams with one of the grinding wheels;  thereafter utilizing both grinding wheels simultaneously to grind two pairs of spaced cam pairs and repeating this step depending upon the number of cam pairs, lastly the final pair of cam pairs is ground utilizing the other grinding wheel. Workspeed for the camshaft is varied depending upon the cam region being ground and to accommodate grinding two cam pairs where the phase angle of one cam pair differs from the phase angle of the other cam pair.

Patent CA-2304331-A1 (CA)
Title: Coated dosage units
Inventor: HARTHOLT GERTJAN PIETER
IPC: A61K9/28
Filed: 1998-09-21
Abstract: Dosage units, such as tablet cores and granules, containing a composition comprising a steroid having two hydrogen atoms at position 3 of the steroid skeleton, are coated. While a conventional sugar coating process involves the application of several layers including, as a surface layer, a sugar coat, it was found that a seal coat such as normally used in a sugar coating process can be used as the surface layer for the purpose of preventing the transfer of the steroid out of the composition. From this novel use of a seal coat, novel dosage units result. The process is advantageous, as it requires fewer steps than before.
