Abstract: Novel sulphur-containing compounds and pharmaceutically acceptable salts thereof are disclosed, which have utility as anti-proliferative agents against mammalian cells. The invention provides a method for synthesizing the sulphur-containing compounds.

Abstract: A new and useful curtain air bag having an inflatable fluid cushion with inflatable fluid sections, and a flexible bladder located within the inflatable cushion. A fluid inlet conduit is configured to direct inflation fluid into the bladder from an inflation fluid source. The bladder is configured to redirect, diffuse and distribute the inflation fluid to the inflatable sections of the inflatable cushion, to inflate the portions of the inflatable cushion in a predetermined manner. Another type of curtain air bag assembly includes an inflatable cushion with a pair of similar volume inflatable sections, on opposite sides of an inlet conduit. In each type of air bag assembly, the fluid can be redirected by the bladder or the inflatable cushion, or by a transverse fluid conduit disposed in the bladder or the inflatable cushion.

Abstract: A side curtain air bag assembly is provided, which has an inlet configured to receive inflation gas, a plurality of inflatable chambers; and a distribution tube in fluid communication with the inlet of the air bag. The inlet and the distribution tube are configured to cause inflation gas to flow along the air bag in a predetermined direction, and the distribution tube has a conical portion configured to reduce the pressure of the inflation gas pressure that is communicated from the inlet, and to distribute the inflation gas to the inflatable compartments of the air bag.

Abstract: An electrode clamping system for an EDM-sinking system provides a two-sided dielectric fluid supply to a clamped electrode by placing supply channels in both the fixed and movable parts of the electrode clamping holder. An automatic control circuit controls the flow of the dielectric fluid with reference to a contamination particle concentration in the gap between the electrode and the workpiece, and automatically reduces the flow to a value at which electrode vibrations disappear when changing from rough machining to fine machining.

Abstract: The electrode clamping system for an EDM-sinking machine according to the present invention includes an electrode clamping holder of adjustable size and a dielectric flow control circuit. The system enables flushing both sides of the electrode through the adjustable holder.

Abstract: A pair of electrodes are spaced from one another so as to define a gap. One of the electrodes constitutes a workpiece to be machined and the other electrode constitutes a machining tool. To machine the workpiece, groups of electrical discharges are generated between the electrodes. The different groups are separated by pauses which are free of discharges, and the electrical resistance of the electrode gap is measured during the pauses. When the resistance decreases to a critical value, the lengths of the pauses and the spacing between the electrodes are increased until the resistance begins to increase from the critical value. Electrical discharge activity is continued during this time. In the event that these measures fail to cause an increase in the resistance so that the critical value is obtained during several pauses, the electrical discharges are stopped and the machining electrode is abruptly shifted away from the workpiece electrode.

Abstract: A direct contact refrigeration system utilizes magnetic fluids, sometimes referred to as ferrofluids, in combination with a suitable refrigerant. The ferrofluid is separated from the refrigerant by magnetic means and circulated to the cooling load. At the same time, the evaporated refrigerant is compressed, condensed and then expanded into direct contact with the warmer ferrofluid returning from the cooling load.
