The stem and spherical head can be formed from a composite block (54). In the a...

An electrical interconnection substrate (20) is prepared to receive both wire bonded and soldered connections (60,64,66) by forming a dielectric solder mask (30) over the substrate (20), with openings (36) in the mask (30) to expose the contact pads (22) for which soldered connections are desired. The substrate (20) is exposed to a molten solder alloy (44) in a wave soldering process that dissolve...

A hollow plastics moulded deck structure, preferably rotationally moulded as one piece and suitable for use in a roof or a roller pallet, has a base 1 and deck 2 interconnected by an array of hollow pyramidal supports. Each support is formed by flat walled webs 5, 6 and 7 which extend from sides of polygonal, preferably triangular, openings 4 in the base 1. The apices of the supports are integral ...

An inductor for drawing one fluid into another (e.g. air into fish-pond water) comprises an insert (12) located in a duct (10) to define narrowing (15, 16) and widening (19, 20) passages on either side. The first fluid, e.g. water, flows along these passages and draws the second fluid, e.g. air, into it via egress holes (24). A valve (25) can be moved in the duct to vary the size of the narrowing ...

A pallet for the cold storage or transportation of goods consists of a single framework (1) molded from a plastics material, and comprising elongated compartments arranged in parallel and filled with a refrigerant. The compartments define slots (6) in the framework. Two parallel sets of aligned holes (7) may be provided at right angles through the compartments (2) for the prongs of a forklift. The...

The invention relates to a product and to a method for making an impervious barrier mass suspension, especially for the erection of slotted impervious barriers by the single-phase process, based on bentonite, ground blast-furnace slag and activators for the blast-furnace slag, the activator for the blast-furnace slag being kept separate from the dry mix, which essentially consists of bentonite and...

A process is described for the operation of a multiple zone batch treatment system for biological or biophysical treatment of wastewater. The system comprises two or more batch treatment zones (10,12) with wastewater passing sequentially through all treatment zones. After the mix and settle batch steps occur for all zones, influent wastewater flows into the first zone (10) and displaces clarified ...

In a computer system, each program has a program attribute list associated with it, for associating different aggregates of program attributes with each of a number of invocation contexts in relation to that program. In operation, a process is given attributes depending on the current context/program combination, as determined by the program attribute table for that program. The program attributes...

A risk management system for use in a health care facility which receives patients who may be experiencing cardiac problems, the system including a first input port for receiving inputs derived from electrocardiograph measurements of a patient; a predictive instrument for using the inputs to compute a probability of the patient having a particular heart condition; a printer for generating a risk m...

An electronic package (10) which includes a substrate (11) having a dielectric layer (13), a circuitized layer (15) located on one surface of the dielectric and a thermally and electrically conductive layer (17) located on a second surface of the dielectric, this thermally and electrically conductive layer designed for providing enhanced heat removal from the package's semiconductor device. A pede...

A method of terminating, under emergency conditions, an olefin polymerization reaction conducted in the presence of a transitioned metal based catalyst in a gas phase reactor by using a recycle gas from the reactor or a feed stream to the reactor to operate an expander associated with a circulator which maintains fluidized conditions in the reactor while introducing a kill gas into the reactor to ...

An expandable, balloon-catheter-delivered intra-vascular stent (10), especially adapted for cardiovascular applications, having a plurality of protrusions (15) on its outer surface for engaging the artery walls in which it is disposed. The protrusions are formed from the body of the stent in a unitary, one-piece manner. Apertures (20) are formed in the stent body from the space vacated in the body...

In combination with a multiprocessing/multiprogramming computer system having a ring protection mechanism for protecting computer programs from unauthorized access, a new call instruction architecture is implemented partly in firmware and partly in hardware. Also, a new stack mechanism stores hardware managed control information in a control frame and software controlled data in a data frame.

A radio arrangement and method allows a portable (210) and a mobile (212) to uniquely communicate on a radio system having at least one remote system site (114).
