Abstract: A protective sealing plug system for towing hitch receivers is provided having a main body for fittingly engaging within the cavity of a towing hitch receiver. The body is formed of a series of aligned segments each formed of a resilient or flexible material that retain oils or other corrosion inhibiting substances and hold them in place against the inside of the female receiver tube. A mechanism for urging the flexible material to compress slightly and, in the process, each segment expands slightly to allow engagement within the hitch receiver in a manner that both prevents access by outside elements, but also prevents egress of the main body from the hitch receiver until desired by the user. When installed in the female hitch receiver, the expansion of the resilient body will seal the female receiver tube and prevent the ingress of water, dirt or other damaging elements. Retraction of the resilient body will cause the flexible body to retract, allowing removal from the receiver hitch.

Abstract: A one piece molded tamper evident push-on closure suitable for closing an opening of a bottle, and method for manufacture thereof. The closure includes a cap portion, a latch ring portion and a frangible connector connecting the cap portion and the latch ring portion. The closure includes a plurality of resiliently deformable teeth extending inwardly from the latch ring portion and towards the cap portion for engaging the latch ring portion onto the neck of the bottle. The closure includes a manually engageable tab projecting from the latch ring portion to permit application of a manual force to rupture the frangible connector and permit the cap portion to be at least partially disconnected from the latch ring portion.

Abstract: An ECG monitoring system for ambulatory patients includes a small multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. Processed ECG signals and cardiac event information are sent wirelessly to a cellphone handset for relay to a monitoring center. The ECG monitor is contained in a watertight sealed case with only electrical contacts on the outside of the case. The electrical contacts electrically couple the ECG monitor to the electrodes of the patch during patient monitoring and to a charger during recharge of the battery.

Abstract: A biomedical electrode patch having improved resistance to capacitive coupling to extraneous electric fields. The patch includes a conductive shield and a contact portion formed on an upper surface thereof. The contact portion extends through the film layer and contacts an electrode formed of a material suitable for conducting electrical signals from a patient. Conductive traces formed on the lower surface of the tab extend to contact pads. A nonconductive layer is printed over the traces and can have a shield formed thereon.

Abstract: An aqueous gloss emulsion paint comprises a dispersion of structured composite particles, said structured particles comprising an association of particles of inorganic pigment and polymeric particles. The polymeric particles are formed from a polymer or copolymer having a minimum film forming temperature not greater than 50.degree. C. The component particles of the composite particles are held in association as a result of surface charges on the particles said surface charges on the polymeric particles being of opposite sign to the surface charge on the particles of inorganic pigment. The ratio of polymeric particles to particles of inorganic pigment in the composite particles is from 0.5:1 to 6:1 by volume.

Abstract: A pigmentary material comprises particulate titanium dioxide the particles of which have been treated with a polymeric hindered amine stabiliser. The stabiliser is a polymer having a main chain substantially free of acidic groups and having hindered amine stabilising groups. The stabilising groups comprise at least 35 per cent by weight of the polymer. Preferably, the titanium dioxide particles are also treated with an organic compound such as a polyhydric alcohol, an alkanolamine, a polysiloxane or a fatty acid.

Abstract: In a data processing system that uses segmentation and paging to access data information such as in a virtual memory machine, the cache store need not be entirely cleared each time an I/O operation is performed or each time the data in the cache has a possibility of being incorrect. With segmentation and paging, only a portion of the cache store need be cleared when a new page is obtained from the virtual memory. The entire cache store is cleared only when a new segment is indicated by the instruction. The cache store is selectively cleared of the information from the page whose data information is no longer needed by addressing each level of an associative tag directory to the cache store. The columns of each level are compared to the page address and if a comparison is signaled that column of the addressed level is cleared by clearing the flag indicating the full status of the column in the addressed level. Each level of the tag directory is addressed.
