Title: Method for the manufacture of contact lenses
Inventor: HAGMANN PETER
IPC: G02C7/04
Filed: 1991-04-22
Abstract: Method for the manufacture of contact lenses Abstract In the process described, a limited number of shaping tools (T1, T2, ......, TN) having standardised parameters (for the production of the following contact lens parameters: contact lens diameter, radius of curvature of the rear face of the contact lens, vertex refraction) is used for the manufacture of standardised moulds (M1, M2, ....... , MN ) . Preferably by material-removing machining of the moulds, moulds are produced that have additional altered parameters. The multiplicity of moulds produced in that manner is used for the one-step manufacture (F) of contact lenses (L) having different parameters that largely do not have to he finished.

Title: Adjustable ratchet wrench
Inventor: FOSSELLA GREGORY
IPC: B25B13/00
Filed: 1990-07-20
Abstract: An adjustable ratchet wrench has a housing (24) carried by a handle (20). The housing has a generally cylindrical chamber which carries a disc (42) which in turn supports three equidistantly spaced jaws (26). The mounting disc (42) is connected to the handle (20) by a ratchet assembly (30) whose setting determines the direction in which the tool may be used to turn the nut or other workpiece. The housing (24) also carries a cam disc (74) that engages the jaws (26) and opens and closes them depending upon the direction in which it is rotated. A second ratchet mechanism (32) determines the direction in which the cam disc (74) may be rotated with respect to the mounting disc (42) so as to open and close the jaws (26).

Title: Self-healing rubber article and method
Inventor: MARONIAN HOVANESS H
IPC: B32B25/20
Filed: 1990-06-22
Abstract: 2060898 9100180 PCTABS00003 A thin, multilayered rubber article (20) and method of making it, having greater resistance to the leakage of fluids therethrough, despite repeated stretching and relaxing of the article within range of movement. The article exhibits a ''self-healing'' property to impede fluid leakage despite preexisting, or later formed, pinholes or other small openings through the layers. In the method, the base layer (17) is initially stretched before applying an intimately adhered, thinner overlayer (18) of elastomeric material, thereby to provide a stressed interface between the two adhered layers. Additional overlayers (19) can be applied.

Title: Circular polarization selective surface made of resonant spirals
Inventor: MORIN GILBERT A
IPC: H01Q15/22
Filed: 1992-02-26
Abstract: ABSTRACT        A Circular Polarization Selective Surface (CPSS) for circular polarized electromagnetic waves is formed from a number of resonating elements arranged in a plane.  This type of surface may be used in a wide range of reflector antennas.  Each resonating element is formed from a number of electrically conductive segments connected end-to-end one to the other with each segment having a predetermined length and having a total approximate length of 1 .lambda..  A central segment having a length of about 1/4 .lambda.  determines the resonant frequency for the element.          This central segment extends parallel to the z-axis of a right-hand set of three mutually perpendicular axis x; y and z wherein the circular polarized electromagnetic wave is directed along the z-axis.  A second segment is connected to one end of the central segment and extends parallel to the x-axis with a third segment being connected to the other end of the central segment extending parallel to the y-axis.  Shorter segments connected to outer ends of the second and third segments extend parallel to the z-axis and toward each other so that a free end of one shorter segment can be collected to a free end of a shorter segment of an adjacent resonating element forming a spiral which can be mechanically supported at its outer ends.  This eliminates the need for having support structures in the active area of the surface.

Title: Treatment of androgen-related diseases
Inventor: LABRIE FERNARD
IPC: C07J41/00
Filed: 1990-07-05
Abstract: A method of treatment of androgen-related diseases such as prostate cancer in susceptible male animals, including humans, comprises administering novel antiandrogens and novel sex steroid biosynthesis inhibitors as part of a combination therapy. Sex steroid biosynthesis inhibitors, especially those capable of inhibiting conversion of dehydroepiandrosterone (DHEA) or 4-androstenedione (.DELTA.4-dione) to natural sex steroids (and testosterone into dihydrotestosterone) in peripheral tissues, are used in combination with antiandrogens, usually after blockade of testicular hormonal secretions.      Antiestrogens can also be part of the combination therapy. Pharmaceutical compositions and two, three, four and five component kits are useful for such combination treatment.

Title: Multi-level radio-frequency communication system
Inventor: KOENCK STEVEN E
IPC: H04W40/00
Filed: 1991-07-24
Abstract: 2066587 9202084 PCTABS00010 A digital data communication system enables host computer to communicate with a great number of data terminals having specified functions. Communication from the host computer proceeds through a medium or long distance, high power transceiver and through a multiplex system to one of a number of portable communication devices. The communication devices preferably contain internal power supplies, such as rechargeable NiCad battery packs. The devices may be carried on a person's belt, or may be mounted within or on a service vehicle, for example, a forklift truck for use in warehouse operations or a merchandise delivery route vehicle. The communication devices are adapted to function as communication relay devices between the host computer and selected ones of the data terminals. Each communication device includes a first type, low power transceiver to communicate within a first channel and at a low power transmission level with a selected number of the data terminals which also feature such first type transceivers. Each communication device further includes a high power transceiver to communicate within a second channel with the transceiver of the host computer. A microprocessor operated address controller allows the communication device to control low power communication among the data terminals by receiving and re-transmitting locally directed communications. The controller and the controlling protocol further relays data messages between the low power communication level and host computer. In operation the device receives data messages on one of the transceivers and transmits them on the other.  The communication device further may contain sufficient memory capacity to permit periodic batch type data transmission between the host computer and the communication device. The ability to switch from a high power, high precision and high cost transmission system to a low power, low precision and low cost transmission system at the level at which a great number of data terminal devices are used provides system flexibility at a reasonable cost.

Filed: 1992-10-16
Abstract: - 9 -Abstract Radio Communication System Communication systems, such as radiotelephone systems, allow only a limited number of subscribers. Cellular systems which use directional antennas both at the base stations and at the mobile stations do not make optimum use of the available frequencies. A communication sys-tem which uses phased array antennas at both the base stations and the mobile stations ensures a better utiliza-tion of a predetermined frequency range, suppresses multi-path effects, and is less sensitive to interference.
