Title: Use of anti-mullerian hormone alone or in combination with aromatase inhibitors for reversal of female sexual phenotype in poultry
Inventor: ELBRECHT ALEX
IPC: A61K38/22
Filed: 1992-04-24
Abstract: TITLE OF THE INVENTION USE OF ANTI-MULLERIAN HORMONE ALONE OR IN COMBINATION WITH AROMATASE INHIBITORS FOR REVERSAL OF FEMALE SEXUAL PHENOTYPE IN POULTRY            ABSTRACT OF THE INVENTION       Fertilized poultry embryos are treated with fowl anti-mullerian hormone which may function as an aromatase inhibitor and may also have a trophic effect on developing gonads. Fertilized poultry embryos are also treated with steroid biosynthesis inhibitors or antagonists which prevents the conversion of androgens to estrogens, and anti-mullerian hormone (AMH). By blocking the production of estrogens and enhancing the gonads the genotypic female is converted into a phenotypic male. The phenotypic conversion of females to males gives the treated birds the advantage of male growth characteristics. A single administration of the combination prior to about day 9 of embryonic incubation results in an irreversible change in sexual phenotype which results in enhanced weight gain and feed efficiency.

Inventor: EDER ERICH
IPC: B65C3/16
Filed: 1992-07-31
Abstract: Containers are transported on rotatable support plates which are arranged in a circle on a rotating turntable.  The leading edge of a label is adhered to a container as it orbits past a vacuum-type label transfer drum.  A curved guide which is tangential to the cylindrical body of the container as the orbiting and rotating container passes it causes the label to wrap completely around the container.  One of a circular array of heat sealing elements which are rotating with the  turntable adjacent each support plate is cammed radially outwardly of the turntable into contact with the region on the container where the trailing end overlaps the leading end of the cable.  This fuses the ends of the labels together.  The cam profile is adjustable in length to keep the time during which the heat sealing member is in contact with the label ends overlap constant independently of the rotational speed of the turntable.

Title: Polymer-modified particulate titanium dioxide
Inventor: ROULSTONE BRIAN J
IPC: C08J3/215
Filed: 1992-12-18
Abstract: ABSTRACT POLYMER-MODIFIED PARTICULATE TITANIUM DIOXIDE    The  tendency  for hard and  irregular particles  of titanium dioxide pigment to adversely affect the sheen and coin mar resistance of a dried coating into which they have been incorporated is reduced by modifying the particles with polymer particles which have been preformed and are therefore of a more pre-determinable shape and size.  The polymer particles are chemically bonded to a polymeric water-soluble compound  containing  moieties  which  are adsorbable onto the titanium dioxide particles so that on mixing a colloidally stabilised aqueous dispersion of the polymer particles with a colloidally stabilised aqueous dispersion of  titanium dioxide particles,  the moieties adsorb onto the titanium dioxide to form a colloidally stable  aqueous  dispersion of  polymer-modified  titanium dioxide which is useful in coating compositions.
