Title: A brush-making machine
Inventor: BOUCHERIE BART GERARD
IPC: B29C45/14
Filed: 1995-03-28
Abstract: A brush-making machine with a mold for injection molding of brush bodies is disclosed. The mold comprises a stationary mold part (10), a movable mold part (12) and a pair of complementary mold parts (14a, 14b) fitting into a recess (16) of the movable mold part (12). The complementary mold parts (14a, 14b) have tuft insertin holes (24) therein. While one of the complementary mold parts (14a) fills the recess (16) of the movable mold part (12) and a brush body is injection molded with tufts of bristles embedded in the molding material, the other complementary mold part (14b) is in front of a tuft feeder for introducing tufts of bristles into the tuft insertion holes (24). The tuft feeder comprises a plurality of tuft picking and transfer tubes (32) which are movable to pick out tufts of bristles from a bristle container and to transfer each of these tufts to a position adjacent one of the tuft insertion, holes (24).

Title: All-round sealing section
Inventor: STEFFEN FRIEDHELM
IPC: E06B3/62
Filed: 1996-02-13
Abstract: A seal that can be used in groove surfaces, in permanent glasswork, or in casement windows and is comprised of a sealing profile 1 having a profile base 3 and an anchoring wedge 2.  On the side of the profile base 3 that is opposite the anchoring wedge 2, a sealing pad 4 and a sealing lip 5 are formed, and a nose strip 6 is positioned on the end of the sealing pad 4.          These parts of the sealing profile 1 are made of a thermoplastic rubber.  They are to be joined to the semi-finished closure of the window shortly following extrusion by the manufacturer.  The corresponding semi-finished product can then be cut to size and joined by the window builder with the sealing profiles 1 being bonded together at the same time so that the entire seal is guaranteed.  This makes the window builder's step of "inserting the sealing profile" completely unnecessary.

Patent CA-2208474-A1 (CA)
Inventor: GO HIDEYUKI
IPC: H04N9/28
Filed: 1997-06-23
Abstract: An apparatus to adjust digital convergence while displaying the external video signal.  The cursor/test pattern signal is generated by the control signal of an address controller.  A video circuit selects and displays either one or both of the output of a cursor/test pattern generator and the external video signal on the screen.  Adjustment points on the screen may be selected using a control panel. The apparatus allows data adjustment of all points which are on the same line as the  selected adjustment point with data identical to that of the selected adjustment point.  The phase of the correction data read from the nonvolatile memory can be adjusted by moving a  mark created from data stored in the nonvolatile memory to the screen center using the up, down, left, and right keys on the control panel.

Title: Device and methods for plasma sterilization
Inventor: GRAVES CLINTON G II
IPC: A61L11/00
Filed: 1995-12-28
Abstract: The invention provides methods and apparatus for sterilizing articles. According to one exemplary method, at least one article is placed into a chamber and a vacuum is applied to the chamber. After the pressure within the chamber is sufficiently reduced, water vapor is introduced into the chamber and electromagnetic radiation energy is applied to produce a plasma. In one paticularly preferably aspect, the chamber is allowed to reach a static condition before the water vapor is introduced. In this way, the water vapor is able to equally distribute itself throughout the volume of the chamber so that an equally distributed plasma can be produced upon application of the electromagnetic radiation energy.

Title: Surfactant compositions
Inventor: WILLIAMS MARTIN SPENCER
IPC: C09K23/42
Filed: 1996-01-03
Abstract: Surfactant compositions including end-capped hydrocarbyl polyalkoxylate and/or fatty acid polyalkoxylate and organopolysiloxane having one or more polyoxyalkylene side chains are good immediate and long term spreaders particularly on fibrous hydrophobic synthetic polymeric substrates such as spun-bonded, non-woven materials made e.g. form polyolefins, especially polypropylene, or PET.  Particularly useful alkoxylates are of one of the formulae (Ia to Id):  R1O.(AO1)n.R2 (Ia); R3.CO2.(AO1)n.R2 (Ib); R14O.[EO i.PO j].R15 (Ic);  or R14O.(AO2)k.(AO3)1.(AO2)m.R15 (Id), where the various substituents and indices have defined meanings and useful silicones include those of the formula (II): R43SiO.[R42SiO]x.{(R4Si[(O.R5.(AO2)m.R6]O}y.SiR43, where the various substituents and indices have defined meanings. Usually the coating compositions will include specific active materials particularly lubricants especially alkoxylate lubricants.  The compositions are water compatible (dispersible or soluble) and primarily biodegradable. The coated substrates find application as carpet backing and geotextiles. In carpet backing, the water compatibility of the compositions makes it possible to avoid tip frosting of carpet on subsequent dyeing.
