Title: Child-Resistant Package Having Preloaded Locking Mechanism
Inventor: HAMILTON PETER W
IPC: B65D50/04
Filed: 1992-08-27
Abstract: A package for storing and dispensing potentially dangerous materials, such as medicament tablets or the like, said package being resistant to opening by children but readily openable by adults, particularly adults having impaired manual dexterity of their hands and/or fingers. In a particularly preferred embodiment, the package comprises a bottle (12), a collar (32) which is secured in place over the uppermost portion of the bottle (12) and a closure (52) which is secured to the finish portion of the bottle by means of complementary screw threads. The collar (32) preferably includes a pair of resiliently deformable spring-like pushtabs (34) containing vertical extensions (36) which engage interlocking teeth (62) on the innermost surface of the closure skirt (60) when the closure (52) is fully assembled onto the bottle (12). To remove the closure (52), the opposed pushtabs (34) must be manually depressed prior to applying unscrewing torque to the closure (52) to disengage the pushtab extensions (36) from the interlocking teeth (62) on the closure (52). In a particularly preferred embodiment, the spring-like pushtabs (34) are generally outwardly directed prior to application of the closure to the package. Advancing the closure (52) onto the package until the teeth (62) on the innermost surface of the closure's skirt (60) interlock with the vertical extensions (36) of the spring-like pushtabs (34) causes a degree of resilient deformation of the spring-like pushtabs (34) so that the vertical extensions (36) of the pushtabs (34) are in contact with and exert a preloading force against the corresponding innermost surfaces of the closure skirt once the closure has been securely applied to the package. Quite unexpectedly, it has been learned that preloading the vertical extensions of the reiliently deformable spring-like pushtabs against the corresponding inner-most surfaces of the closure skirt in the foregoing manner considerably enhances the child resistance of the package without increasing the difficulty of opening for older adults or those having impaired manual dexterity. Methods for producing the improved package are also disclosed.

Title: Method of extracting proteins utilizable in foodstuffs from a protein-containing substance
Inventor: NEUMUELLER WALDEMAR
IPC: A23J1/12
Filed: 1992-10-08
Abstract: A B S T R A C T :            In the method described, a protein-containing substance is first taken up in an alkaline solvent to give a solution. Insoluble constituents of the substance are separated off, the solution is neutralized and desalinated, and then the proteins contained in the solution are concentrated. The decomposition of the protein-containing substance is carried out at room temperature using homogenization equipment. The heat dissipated into the protein-containing substance during homogenization is simultaneously removed. The pH of the alkaline solvent during the decomposition is over 11.5 and/or decomposition is carried out in the presence of a detergent, in particular sodium dodecyl sulphate (SDS).

Title: Alkyl-substituted cellulose-based sustained-release oral drug dosage forms
Inventor: SHELL JOHN W
IPC: A61K47/38
Filed: 1993-03-17
Abstract: Sustained release oral drug dosage forms that comprise a tablet or capsule of a plurality of particles of a solid-state drug dispersed in alkyl cellulose such as hydroxyethylcellulose or hydroxypropylcellulose. Once ingested the tablet or capsule disinte-grates to disperse the particles into the stomach where they imbibe water to cause them to swell and also to become slippery, thus enhancing their retention in the stomach. Imbibed water from the gastric fluid dissolves the drug entrapped in the particles and the resulting solution diffuses from the dispersed particles, assuring that no solid drug, which is more irritating, contacts the mu-cosal tissue. A number of embodiments of the dosage form utilizing different drugs are exemplified and the benefits are ex-plained. Aspirin is one example.

Title: Uv water sterilizer with turbulence generator
Inventor: SZABO LOUIS
IPC: B01J19/12
Filed: 1994-09-26
Abstract: A sterilizer for water and other fluids employs ionizing radiation as an antimicrobial agent.  The sterilizer is housed within an elongate exposure chamber, which houses a radiation source such as UV lamp.  An array of flat baffles spans the interior of the chamber, with each baffle partly blocking the passage of fluid as it flows through the chamber along its elongate axis.   Each baffle is provided with a channel to permit fluid to flow past the baffle, with the channels of neighbouring baffles being offset from each other to generate a sinuous and turbulent flow of fluid as it traverses the length of the chamber. The fluid stream is sequentially diverted towards and away from the radiation source.

Abstract: The present invention relates to a rotor for a dynamo electric machine serving as a synchronous generator as well as being designed to operate as a variable speed motor for starting a prime mover for the synchronous generator.  The rotor is comprised of a rotor core, and a plurality of slots disposed around the circumference of the rotor core and extending along the axial direction of the rotor core.  Rotor windings are accommodated in the slots and wedges are accommodated in the slots over the rotor windings near the surface of the rotor core for preventing the rotor windings from being pushed out of the slots due to the centrifugal force caused by rotation of the rotor.  The wedges where eddy currents flow are formed by Cu-0.05 ~ 4wt% Zr-0.3 ~5wt% Ni-0.2 ~ 1.5wt% Si having a 0.2% proof stress equal to or more than about 20Kg/mm2 and an electrical conductivity equal to or more than about 20% IACS (International Annealed Copper Standard).          Damage of the rotor elements due to electrolytic corrosion are prevented.

Inventor: ANDERSON TODD WILLIAM
IPC: F16L37/20
Filed: 1995-06-07
Abstract: An elbow coupler includes a linkage for locking the coupler to an adapter. The linkage has a resilient, laterally deflectable link that limits the forces applied to the linkage thereby preventing the components of the linkage from being overstressed. A spring loaded, blocking sleeve prevents the coupler from normally remaining upright on an adapter, unless it is locked thereon through use of the locking linkage. A flapper valve is interconnected with the blocking sleeve to the end that the valve is normally closed and then opened when the coupler is locked onto an adapter.

Title: Little helper
Inventor: FASAN OELIS BRUNO
IPC: G09B9/042
Filed: 1995-09-25
Abstract: A child on a tricycle/small bicycle is much lower than an upright adult. At present the basic method used by an adult to teach a child how to ride is to bend over in an awkward stance, holding both the child and the tricycle/small bicycle. Keeping this stance for prolonged periods of time required to allow a child to learn the riding skills can cause back strains and in some cases serious back problems.   Children enjoy exploring their neighbourhood (local park, corner store etc.). However, the child has not built up the stamina to go these distances and many times is unable or unwilling to ride the tricycle/small bicycle back home. The adult is left with little choice but to carry the child and the tricycle/small bicycle. This creates an awkward and unsafe situation for both the adult and the child.   With this invention these situations are avoided as the invention allows the adult to retain his or her normal posture at all times while allowing the adult to push or pull the tricycle; thus allowing the child to learn the skills of riding a tricycle/small bicycle.

Abstract: The invention relates to providing elastication in defined areas of an article by applying a thermoplastic elastomeric composition under elastic tension to the article and deactivating or partially deactivating elastic tension in the composition outside the said defined areas.  Elastic tension may be deactivated by (i) heating to a temperature of at least the inversion temperature between G' and G"; or (ii) heating to a temperature below the inversion temperature between G' and G" with application of a pressure equal to at least the value of G' at that temperature.    The article may be an absorbent article, such as a disposable diaper and elastic tension may be retained in the crotch area and deactivated outside the crotch area.          Alternatively the thermoplastic elastomeric composition may be applied to the article as a thread or strip and subjected to complete or partial deactivation of elastic tension at a series of points along the length of the thread or strip in order to improve adhesion to the article.
