Granted: 2000-12-12
Abstract: A sustained release capsule adapted to be inserted into the rumen of a ruminant animal and means for retention of the capsule in the rumen. A sustained release capsule adapted to be inserted into the rumen of a ruminant animal through its oesophagus and retained within the rumen over a prolonged period to continuously deliver a biologically active composition carried in the capsule, comprising an elongated tubular body comprising a tube and an end cap secured to one end thereof for substantially enclosing the biologically active composition, the other end of the capsule being a delivery end, the body having an opening at the delivery end of the capsule for delivery of the composition to the rumen, and a plurality of retention arms attached to or formed integrally with the cap, the arms being adapted to extend outwardly from the cap for retaining the capsule in the rumen, the arms being resilient to enable them to bend from their outwardly extending positions toward the body so that they lie alongside the body allowing the capsule to be inserted through the animal's oesophagus, the resilient arms normally extending from the body at an angle between 75° and 90° with respect to the axis of the tubular body, and for each arm said cap has an external curved surface disposed with respect to the arm so that when the arm is bent toward the body, the arm contacts the curved surface and the curved surface controls the bending of the arm so that the arm does not bend abruptly, said arms being adapted to return to their outwardly extending positions when the capsule reaches the rumen, characterised in that said cap is secured to said one end by means of at least two circumferential beads having at least one sealing ring located therebetween.

Title: Polymeric compositions
Inventor: LANGLEY JOHN GRAHAM
IPC: C11D3/386
Filed: 1992-05-14
Granted: 2003-07-01
Abstract: A particulate composition comprises particles having a substantially anhydrous core comprising a matrix polymer contain-ing active ingredient, a layer of hydrophobic oil around the core and a shell of polymer around the oil layer, wherein the solid ma-trix polymer is sufficiently hydrophobic that it will partition preferentially into the oil rather than into water. The composition can be a powder or a stable liquid dispersion. The active ingredient is preferably a detergent enzyme and the composition can there-fore be a stable liquid laundry detergent. The composition can be made by providing an aqueous solution of encapsulating po-lymer, providing a substantially anhydrous dispersion in oil of particles of a matrix polymer containing active ingredient, dispers-ing this dispersion into the aqueous solution and causing a solid polymer shell to form around the droplets of the matrix particles.

Granted: 2000-02-29
Abstract: An improved coupling assembly includes a combined clutch and brake assembly. Springs are provided to urge the brake assembly to an engaged condition. A first pressure chamber holds fluid pressure to assist the springs in urging the brake assembly toward the engaged condition.      A second chamber holds fluid pressure to urge the clutch assembly toward the engaged condition and to urge the brake assembly away from the engaged condition. Fluid is supplied at a relatively low pressure through the first chamber to provide for a controlled actuation of the brake assembly to the engaged condition under the combined influence of the springs and the pressure in the first chamber and to provide for the transmission of a controlled amount of braking torque when the brake assembly is engaged. Fluid is supplied to the second chamber at a higher pressure to overcome the influence of the springs and operate the clutch assembly to the engaged condition.      A quick release valve arrangement is provided in association with the second chamber to enable the fluid pressure to be quickly exhausted from the second chamber and the brake assembly engaged.

Title: Apparatus and method for reading and or verifying the contents of sealed envelopes
Inventor: BERSON WILLIAM
IPC: G06K9/20
Filed: 1993-10-28
Granted: 1996-11-05
Abstract: This invention relates to reading and analyzing the contents of sealed mail.  The invention has utility in the sorting of sealed mail and in the matching of mail envelopes and its contents.  The contents of sealed mail are read by having a light in the near infrared directed to the sealed envelope and creating an image of the printed matter on the contents by directing the light to an optical detector.  The image thus received is analyzed and a determination can be made whether contents are of high value or whether the addresses on the envelope match the addresses of the contents.  If the envelopes are not addressed, the address can be printed on the envelope after analysis of the address block of the contents.

Abstract: A kit for the repair of damaged prosthetic devices provides for the economical repair of such prostheses. The kit is directed primarily to the repair of externally worn silicone gel filled breast prostheses, which prostheses are relatively costly and perhaps more vulnerable to damage than other types. The basic member of the kit is a thin, flexible adhesive backed tape of vinyl or other suitable material, which tape may be stored on a backing sheet. The backing sheets may be in the form of a roll, or alternatively several planar sheets may be included in a relatively flat container for persons who may not be able to conveniently carry a bulky roll. Several shapes and sizes of tapes may be included a single kit, and different kits may include different coloring, shading and/or texture in order that the user may most closely approximate the proper coloring, shading and/or texture of the damaged prosthesis. However, each of the repair tapes in a given kit are of like coloring, shading and texture in order that all repair tapes in that given kit will closely approximate the coloring, shading and/or texture of the prosthesis for which the repair kit was made.

Abstract: A bleeder valve venting system includes a bleeder valve that is provided, and adapted to mount through a lid aperture, the valve having an enlarged upper cap portion, a cylindrical intermediate portion which extends through the lid aperture, and a semi-spherical lower working portion. A central axial through-bore extends downward through the cap and intermediate portions, and a slit is provided to extend upward into the lower valve portion and communicate with the through-bore. The lid aperture is sized to admit the valve with interference, whereby establishing a liquid tight seal between the valve body and portions of the lid defining the aperture. The valve is composed of resilient material and the slit is dimensioned to open to a width sufficient to admit air when a pressure differential exists between the inside and outside of the container. As the slit opens, the lower working valve portion is compressed against inside surfaces of the lid, and, upon equalization in air pressure, the working valve portion reacts to force the slit closed.
