Abstract: Implantable heart monitors, such as defibrillators and cardioverters, detect abnormal heart rhythms and automatically apply corrective electrical shocks to the hearts of patients. A critical component in these devices are the capacitors that produce the electrical shocks. One problem with some of these capacitors is that during operation they generate internal gases, which over time accumulate and exert pressure on their cases, often forcing the cases to swell or bulge and potentially compromising capacitor and monitor performance. Accordingly, the inventors devised novel capacitors that include titanium and/or other hydrogen-getting materials and structures, for preventing the development of excessive pressures within capacitor cases.

Abstract: A multistage refrigeration system is disclosed, and particularly a system with a thermal storage reservoir disposed in a secondary refrigeration loop of the system. The reservoir stores thermal reservoir material in heat exchange relation with the refrigerant in that secondary refrigeration loop. A primary refrigeration loop transfers heat from the secondary refrigeration loop to ambient. A third refrigeration loop absorbs heat from a product to be cooled and transfers that heat to the secondary refrigeration loop. The thermal reservoir material may undergo a liquid/solid phase change, and preferably has a freezing point at about 20.degree. F. (-7.degree. C.). The multistage refrigeration system of the present invention is particularly adapted for use in stadium or arena settings, where rapid cooling of mass quantities of canned or bottled beverages for immediate consumption is desired.

Abstract: A method and apparatus are provided for using certain hydrofluoroethers (HFEs) as low temperature heat transfer media in secondary loop refrigeration systems. These materials exhibit a low, somewhat linear Temperature Difference Factor over the temperature range of -15.degree. C. to -65.degree. C., making them ideal for use as low temperature heat transfer media. The HFEs of the present invention are nonflammable, nontoxic, environmentally benign, and have a high heat transfer capacity and low viscosity over the required operating temperatures. Furthermore, since these materials have high boiling points and low freezing points, they are not prone to phase changes over the required operating temperatures, and do not require pressurized systems.

Abstract: In an electronic data processing apparatus blocks of returned memory 3 are linked by address pointers starting with a pointer in a table 1. Each pointer in the table 1 points to memory of within a predetermined size range varying by integral powers of 2. The memory blocks pointed to by each table pointer are sorted in order of size (alternately by frequency of use). Searching for memory of size needed is very efficient as it is limited to memory blocks within a size range. Additionally, returned memory blocks (7) of the same size as a block 3 are not in the sort list, but are pointed to by the block 3 of the same size and are used when that size block is selected.

Abstract: An improved logic module comprises integrated circuit chips located in channels. The channels convey a flow of a cooling fluid or a combination of cooling fluids, bringing the cooling fluid into contact with the integrated circuit chips. Flow blockers and power blades form boundaries of the channels and substantially exclude the undesirable entry or exit of cooling fluids at the boundaries. A support frame holds the logic modules of a cluster of logic modules in a generally parallel relationship. Sealing plates between logic modules and an assembly gasket substantially prevent flow short circuiting. The power blades mate sealably with a horizontal buss to conduct electric power to the module.
