Abstract: A container for contaminated materials having an upper entry chute (29) and a hinged door (12) which normally hangs vertically closing the inner end of the chute. When the container is full the door (12) can be lifted until hooks (39) at its lower end engage in apertures (42) in the lid of the container and the whole door can then be pivoted into a closed position closing the entry opening to the chute and thus providing protection from the contaminated chute surface (29). The door has barbed detents (44) which engage in apertures (48) to hold the door positively sealed in its final closed position. In the example illustrated in Figure 6 there is a separate hinged closure (72) for closing the outer end of the entry chute.

Abstract: The invention relates to knives and in particular to knives of the type of construction described and claimed in British Patent No 2108887, where the blade has a V-shaped cutting edge centrally located on a parallel sided blank with the edge flat ground to one side and ground with formulations such as serrations or serrations and scallops. The object of the invention is to improve such knives by increasing the strength at the cutting edge, which objective is met by a construction where along that side of the V-shaped cutting edge provided with formulations a number of interruptions are provided in spaced relationship along the length of the cutting edge. The interruptions can take the form of areas free from formulations or can take the form of single large serrations spaced along the length of the cutting edge.

En mottager (70) påviser den bestemte OAM-modus som blir utsendt på en prøve- og feilebasis ved forsøk på å dekode de mottatte data ved bruk av forskjellige OAM-modi inntil en synkroniserlngstllstand blir påvist. Synkronlserlngstilstanden kan kreve at flere forskjellige synkroniser- ingsprøver må bli klare. I en bestemt utførelse er en første synkrniseringsprøve klar når en renormaliser- ingshastlghet for en gitterdekoder (90) ligger under en terskelverdi. En andre synkroniseringsprøve er klar når et første synkroniseringsord blir påvist i de mottatte data. En tredje og avsluttende synkroniser- ingsprøe er klar når et andre synkroniseringsord blir påvist i de mottatte data.

Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by contacting the salt-impregnated support with a reactive solution in two separate fixing stages wherein the treated support is dried and allowed to stand prior to treatment in the second stage to precipitate the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2 during the vinyl acetate forming reaction.

Abstract: En spyleintervallindikator for oppløselige poser som kan kastes i en klosettskål, for å indikere for en bruker, så snart posen (10) er kastet i klosettskålen, når et tilstrekkelig spyleintervall har forløpt, slik at posen (10), når klosettet deretter spyl- es, raskt vil oppløses uten å tilstoppe eller hindre strømmen av vann og av- fallsmateriale gjennom systemets av- løpsledninger . Spyleintervallindikatoren (18) omfatter optisk skjelnbare tegn som er trykt på eller på annen måte er fes- tet til en fremvisningsflate (17) av en pose (10) og normalt er skjult av et vannoppløselig, ugjennomsiktig lag (Ila). Det ugjennomsiktige lag kan være i form av en ytre plate (20) som er festet til posen, eller et vannopp- løselig lag (Ila) av selve posen (10) som omfatter pigment for å gjøre det ugjennomsiktig og avskjerme indikatoren (18) fra betraktning.

Abstract: This invention relates to interdigitation-fusion (IF) liposomes and gels. These liposomes and gels capture high solute to lipid ratios, including bioactive agent. This invention also relates to the discovery that the fusion of liposomes to produce IF gel and liposomes according to the present invention is size dependent. The present invention also relates to a method for producing IF liposomes and gels. In the method of the present invention, sized liposomes formed by sonication, extrusion or alternative processes are fused in the presence of ethanol or other suitable inducer. This process results in a composition of the present invention in gel form. To produce liposomes, the gels are exposed to a temperature usually but not necessarily above the transition temperature (Tm) of the lipid used. The temperature required by the methods of the invention is that temperature which induces a change in the material properties of the mixture. The inducer may also be removed. The result is a composition comprising liposomes containing high solute to lipid ratios. The IF liposomes and gels of the present invention may be used in combination with numerous solutes, especially including bioactive agents.
