Title: Device and process for the electrolytic separation of metals with the aid of a rotating cathode system
Inventor: LEUDOLPH JUERGEN
IPC: C25C7/00
Filed: 1994-11-08
Abstract: A device is proposed for the electrolytic separation of metals in a metal recovery cell with a rotating cathode system. The latter comprises a supporting cylinder (11) with at least one slit (21) and at least one contact chamber (25) behind the slit, at least one sheathed cathode (20), contact elements and a drive shaft (5) provided with current supply means. The said device facilitates simple manipulation of the supporting cylinder (11) with the sheathed cathode (20) and the choice of material for the sheathed cathode, since this material can be matched as closely as possible to the particular electrolytic separation process in question. The process disclosed can be used in the extraction of metals from metal-containing solutions of sufficient electrically conductivity and in the depletion of such solutions for the purpose of reintroducing them into the work process.

Title: Method of manufacturing a luminescent screen for a crt
Inventor: RITT PETER MICHAEL
IPC: H01J9/227
Filed: 1995-08-17
Abstract: In an improved method of electrophotographically manufacturing a luminescent screen assembly for a color CRT on an interior surface of a faceplate panel, a volatilizable organic conductive (OC) layer is provided on the interior surface of the panel and a volatilizable organic photoconductive (OPC) layer overlies the OC layer. The method includes the steps of: establishing a substantially uniform electrostatic charge on the OPC layer; exposing selected areas of the OPC layer to visible light to affect the charge thereon; developing the selected areas of the OPC layer with a triboelectrically charged, dry-powdered, first color-emitting phosphor; sequentially repeating the charging, exposing and developing sequence for triboelectrically charged, dry-powdered, second and third color-emitting phosphors to form a luminescent screen comprising picture elements of triads of color-emitting phosphors; fixing the phosphors to the underlying OPC layer with a suitable fixative; filming the phosphors; and aluminizing the filmed phosphors. The improvement comprises the fixing step utilizing an electrostatic spray to uniformly contact the phosphors and the underlying OPC layer with the fixative, without moving the phosphors.

Title: A connector element for telecommunication
Inventor: KJELDAHL POUL
IPC: H01R13/6464
Filed: 1994-03-11
Abstract: In telecommunication systems of the copper wire type it has been found that for the handling of data with very high transmission capacity, a bottle neck problem resides in the use of associated connector elements, inasfar as these have not so far been developed to the same high adaptation standards as, for example, the cables themselves. The invention provides for a connector element in which the internal leads are arranged in a highly sophisticated manner, such that the connector element, as far as its impedance is concerned, practically eliminates itself and therewith the said bottle neck problem.

Patent CA-2162060-A1 (CA)
Inventor: POTTER CLIVE
IPC: A63B57/00
Filed: 1995-11-03
Abstract: A device designed for retrieving golf balls. The mechanism includes an extension rod and a retrieval cup. Integral to the cup is an internally positioned ring which includes a series of hinged retaining pawls. By means of the extension rod the cup is positioned over the golf ball. A continued vertical downward movement causes the pawls to rotate on an internal ring thereby accepting the golf ball within the recovery cup. As the cup is raised, the pawls will grip and hold the ball within the cup. The golf ball retriever can then be moved to an area where the ball can be dislodged. To disengage the ball from the cup, the retrieval tube is rotated thereby allowing the ball to fall free through the opposite diameter of the recovery cup.

Abstract: A one-way valve with bacterial  filter apparatus having a valve and filter assembly with a  shield member connected  thereto  being  extended laterally  to  provide  a flexible  impervious  material  to  provide  protection  from bacterial transmission.  The valve and filter assembly includes 1)  a respirator bottom assembly; 2)  a flapper valve member operable to act as a one-way valve;  3)  a bacterial filter assembly to prevent transmission of bacteria therethrough in either direction; and 4) a respirator top assembly mounted on the respirator bottom assembly and having the bacterial filter assembly mounted therein.  The valve and filter assembly has a one-way valve therein which permits air to be transmitted therethrough into a patient receiving CPR but not permitting air flow from the patient receiving CPR to the person applying the CPR . A fluid flow channel directs air flow from the person applying CPR to the patient receiving CPR through the bacterial filter assembly.  A fluid flow exit channel directs air flow from the patient receiving CPR laterally of the valve and filter assembly and the flapper valve member is closed to seal off the fluid flow channel to the person administering CPR.

Title: Apparatus and method for printing a color filter
Inventor: EVANS JAMES LEO
IPC: G02F1/1335
Filed: 1995-10-04
Abstract: A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised patter corresponding to the desired black matrix pattern is formed on the transfer layer by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed cells is thereafter retained, preferably by curing during deposition to the substrate.
