Title: Method and apparatus for the manufacture of slabs of ceramic material
Inventor: TONCELLI MARCELLO
IPC: B28B7/36
Filed: 1998-04-11
Abstract: During the manufacture of slabs of ceramic material from a mixture formed by a grannulated material and by an inorganic binding phase, the starting mixture is spread on a support constituted by a mechanically resistant fabric or felt covered with a layer or sheet of release material permeable to water vapour such as paper, and the layer of mixture is covered with a protective sheet of release material, preferably rubber, after which forming is carried out by the application of a compacting pressure under vacuum combined with the simultaneous application of a vibratory motion; the resulting raw slab is released from the rubber sheet, transferred by pincer means to a support or metal grid used for the drying and firing steps, and is then sent to a drying oven after which, when the felt sheet has been removed, the visible surface is covered with a layer of refractory material and the raw slab is turned over and sent to the firing kiln where the permeable paper is removed by burning.

Patent CA-2292120-A1 (CA)
Inventor: KATERBERG JAMES A
IPC: B41J2/085
Filed: 1999-12-13
Abstract: The present invention utilizes two transverse or "extra" electrodes below the charging electrode in an ink jet printing system, to facilitate and improve the detection of shorts, or the detection of unwanted ink on the charge plate of an ink jet printhead. Upper and lower defection electrodes can be formed by the same photolithographic and electroforming processes used to form the charging electrodes. The detection electrodes are electrically shielded, and connected to short detection electronics at both ends of the charging electrode array. This provides some redundancy in connecting to the short detection electrodes. It is then laminated onto a rigid dielectric substrate, such as a ceramic.

Title: Device for implanting filamentous materials
Inventor: LUESCHER PATRIK
IPC: A61B17/12
Filed: 1998-09-14
Abstract: The invention relates to a device for applying a filamentous implant by means of a pressure-generating unit which is connected to a housing containing the thread to be implanted. The housing opens out into a channel used for delivering the thread externally.  The pressure generation unit generates a static pressure on a fluid contained inside the device, said fluid pushing the thread to be implanted through the distal narrowed tip of the channel, towards the exterior or into a tissue or a body cavity. The fluid remains inside the device in the course of this process. The distal end of the device can be plugged in order to prevent the fluid from exiting after application of the implant. The application can be stopped once an adequate quantity of the implant material has been implanted by severing the thread in the vicinity of the distal end of the channel or at the proximal end.
