Title: Ringworm vaccine
Inventor: STROBEL MICHAEL
IPC: A61P31/04
Filed: 1990-03-09
Granted: 2001-05-08
Abstract: A ringworm vaccine is disclosed comprising antigen isolated from at least one dermatophyte and a suitable carrier. The "antigen" can include a single antigen from a dermatophyte or a plurality of antigens as long as at least one antigen is included which will produce a sufficient immune response to confer resistance to ringworm infection upon the recipient of the vaccine. The antigen can also be isolated from more than one dermatophyte. If a preparation from more than one dermatophyte is made the antigen can include antigens which are common to all species of dermatophytes employed and/or antigens which are only specific to certain species. A method of producing such a ringworm vaccine is also disclosed. The method comprises making an antigen preparation comprising the dermatophyte antigen described above and combining the antigen preparation with a suitable carrier. Methods of treating a patient are also disclosed employing the vaccine of the present invention and vaccines produced according to the method of the present invention. Methods are also disclosed for treating a pregnant patient with such vaccines such that the progeny of the pregnancy exhibit resistance to the ringworm infection at birth.

Title: Separable diamond shaped multidimensional filters for composite video endocing/decoding applications
Inventor: LEDINH CHON TAM
IPC: H04N9/78
Filed: 1990-04-27
Granted: 1996-12-03
Abstract: Various 2D and 3D diamond shaped filters for encoding  and decoding  NTSC,   PAL  and ATV  signals  are presented.    The particularity of the proposed system is its separability:  the desired filter configurations are composed  of   multiple   simple   ID   filters   operating individually in their own zero or oblique frequency axis.          In comparison  with existing diamond shaped filters the proposed  systems  offer  substantial  advantages,   low complexity  and  better performance  along the  zero  axes (horizontal,   vertical  and  temporal)  in  the  frequency domain.

Granted: 1994-11-01
Abstract: An information reproduction apparatus in provided with supporting means for supporting a recording medium.   A drive source, for moving the recording medium, is located between an initial insertion position and a reproduction position by driving said supporting means.  Transmission means is included for transmitting the driving force of said  drive  source  to  said  supporting  means  plus retraction  means,  operable  to  force  a  transmission element to retract from said transmission means.   The transmission  element  is  a  part  of  said  transmission means.   Motion means  operable  to  force  the  recording medium to move from the  reproduction position to the initial insertion position under the condition that said transmission element is not engaged in said transmission means, so that in forcibly moving said supporting means, when the drive is out of operation, said supporting means are  released  from  the  drive  force  by means  of  said retraction means,  thereby freeing the supporting means from the resistance force of the drive force.  However, under normal operation, the said transmission element is returned to the said driving force transmitting path, thereby stopping inconvenience to the operation.

Title: Rotating paddle bin level indicator
Inventor: BRENTON RONALD G
IPC: H01H35/18
Filed: 1992-08-24
Granted: 1996-07-02
Abstract: Apparatus for indicating the level of flowable material in a storage bin that includes a motor mounted within a protective enclosure and coupled by a shaft and clutch arrangement to a paddle disposed within the bin to engage material therewithin.  When the material reaches the level of the paddle, drag on the paddle causes the motor to rotate within the enclosure against the force of an adjustable spring to activate switches disposed within the enclosure for indicating material level.  The switches also remove power from the motor and apply power to an electrical resistance heater to warm the enclosure and help prevent condensation at low external ambient temperature.  The paddle is constructed to enhance drag when used in conjunction with low-density materials.

Title: Heated injection molding nozzle with alternate thermocouple bores
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1993-11-10
Granted: 2001-09-11
Abstract: A heated injection molding nozzle having a melt channel which branches outwardly to several spaced edge gates. The nozzle has alternate thermocouple element receiving bores spaced longitudinally along a temperature gradient extending between the heating element and the front end of the nozzle. The nozzle facilitates the temperature control of materials having different thermal characteristics. When molding an amorphous material, a temperature somewhat lower than the prescribed operating temperature is desirable so the thermocouple element is mounted in the rearward bore closer to the heating element.      If it is critical to maintain the temperature of the melt near the prescribed operating temperature for a material such as a crystalline material, the thermocouple element is received in the forward bore further along the temperature gradient from the heating element.

Title: Formation of microstructures using a preformed photoresist sheet
Inventor: GUCKEL HENRY
IPC: G03F7/20
Filed: 1993-11-12
Granted: 2002-12-31
Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.
