Patent number: 4816489Abstract: The present invention relates to the preparation of new derivatives selected from the group consisting of:(i) 1-(aminophenyl)-2-(alkylamino)ethanones of the formula: ##STR1## in which R is CH(CH.sub.3).sub.2 or C(CH.sub.3).sub.3 ; and (ii) addition salts thereof.These new derivatives are useful in therapy, in particular as antidepressants or stimulants for the CNS. They are prepared from 1-(acetylaminophenyl)-2-(alkylamino)ethanone derivatives by deacetylation.Type: GrantFiled: September 10, 1987Date of Patent: March 28, 1989Assignee: Laboratoire L. LafonInventor: Louis Lafon

Patent number: 4804969Abstract: A portable antenna is provided for mounting on a motor vehicle's side window and enabling easy and rapid mounting and removal. The portable antenna includes an outer RF transfer member, a current-fed radiator connected to the outer RF transfer member, an inner RF transfer member, a field-cancelling member operative to cancel the electromagnetic field in the plane of the field-cancelling member, and a pair of generally parallel wire members pivotally connecting the outer transfer member to the inner transfer member and bridging the inner and outer transfer members so as to overlie the side window when the antenna is mounted thereon.Type: GrantFiled: March 4, 1988Date of Patent: February 14, 1989Inventor: Herbert R. Blaese

Patent number: 4804432Abstract: Gloves and other articles are manufactured from a pair of thermoplastic sheets which are drawn along a process line in adjacent, facing relation. A portion of one of the sheets is pushed outwardly to form an outwardly projecting loop, and a thumb-shaped line is formed between adjacent sides of the loop. The loop and adjacent portions of the thermoplastic sheets are then advanced to a finger and hand-forming station, where a thermobonded line of the shape of fingers and hand is formed between the thermoplastic sheets in registry with the thumb-shaped line, while retaining an open wrist portion. One may then cut away the resulting glove at the wrist portion.Type: GrantFiled: February 17, 1987Date of Patent: February 14, 1989Assignee: Bodiguard Technologies, Inc.Inventors: Eran J. P. Jurrius, Geri A. Russ, Travis A. Russ

Patent number: 4798594Abstract: A hemostasis valve is provided for catheters or the like, comprising an elastomeric partition valve secured in a housing. A linear slit extends through the partition valve between the major faces thereof. By this invention, the slit defines a line at each major face, with the respective lines at the major faces being in non-alignment and thus defining an angle with respect to each other. The slit defines at least one generally helical slit section between the lines of the major faces, within the partition valve. Such a partition valve exhibits better sealing characteristics over a wide range of diameters of catheters, leads, or the like penetrating the partition valve, as well as other advantages.Type: GrantFiled: September 21, 1987Date of Patent: January 17, 1989Assignee: Cordis CorporationInventor: Richard A. Hillstead

Patent number: 4796329Abstract: A faucet handle is disclosed having a light-transmissive upper portion (10) and an opaque lower portion (16) which is connected to the handle hardware. In order to prevent viewing of the lower portion and the hardware through the light-transmissive upper portion, an opaque insert (26) is interposed between the upper portion and the lower portion. The upper portion comprises a unitary one-piece molding in which the top and downwardly depending skirt which form the upper portion are formed integrally in order to prevent detachment of the top (12) from the skirt (14). A projection (39) extends downwardly from the top at a central location thereof for carrying a color (40) which is applied to the underside of the projection, which color indicates cold or hot.Type: GrantFiled: March 24, 1987Date of Patent: January 10, 1989Assignee: Injecto MoldInventor: Steven Bory

Patent number: 4796630Abstract: A cardiac pacemaker is provided which has combined defibrillation and electrosurgery protection. The pacemaker includes an implantable housing with a pacing circuit located within the housing and means for attaching a lead to the housing. A protection circuit is located between the pacing circuit and the attaching means. The protection circuit comprises a zener diode and a capacitor connected across the zener diode. The capacitor has a value to provide a relatively low impedance with respect to electrosurgery frequencies and a relatively high impedance with respect to cardiac myopotential frequencies.Type: GrantFiled: March 23, 1987Date of Patent: January 10, 1989Assignee: Telectronics N.V.Inventor: Richard C. Regna

Wire length meter suppling current to a wire from which a signal representative of length is derived
Patent number: 4797604Abstract: An apparatus for determining the length of wires includes connector assemblies, a current source circuit, a voltage gain circuit, analog-to-digital converter, a read-only memory, a microprocessor and a display unit. The connector assemblies are connected across the ends of the wire whose length is to be determined. The current source circuit is used to selectively supply different values of currents to the wire whose length is to be determined. The voltage gain circuit is responsive to the different values of currents for selectively generating a plurality of different voltage levels for each of the different values of currents so as to provide an analog voltage signal having a predetermined range. The analog-to-digital converter is responsive to the analog voltage signal for converting the same to a first digital signal corresponding to a resistance of the wire.Type: GrantFiled: December 9, 1987Date of Patent: January 10, 1989Assignee: Etcon CorporationInventors: Joseph A. Rocci, John Crosetto, Kent L. Earle, David W. Kirby
