Title: Gas cylinder pallet transport - has open slots underneath cylinder receiving spaces and engaged by chain conveyor for transport
IPC: B65D19/38
Filed: 1980-04-17
Abstract: The pallet has in its bottom endwise open slots (22) underneath article receiving spaces so that articles are supported by the undersides of laterally projecting portions (12) of the articles. The slot is used for loading and/or unloading purposes by engaging a chain conveyor (8). The longitudinally-extending pallet parts (18) are connected by framework (17) lifted by a T-piece (28).

Title: Method of and an apparatus for the evaluation of burned-out nuclear fuel elements
IPC: G21C17/07
Filed: 1980-08-01
Abstract: Nuclear fuel elements or slugs are removed from the nuclear reactor cores and subjected to inspection, according to the invention, by introducing a plurality of such elements into a submerged inspection vessel which is then closed, the liquid driven out by compressed air and deionized water (deionate) circulated through the inspection vessel at a constant rate. A portion of the deionized water is branched from the circulating stream at a constant rate and the activity of at least one fission-product nuclide is determined continuously to plot the activity versus temperature, thereby signaling a possible defect in the shell of a fuel element. In addition, ultrasonic vibration is applied in the inspection vessel to the fuel elements so that deposits on the exterior thereof are released into the deionate whose circulating path includes a filter and an ion-exchange column for removal of such deposits.

Title: Shootthrough fault protection system for bipolar transistors in a voltage source transistor inverter
IPC: H02M7/537
Filed: 1980-09-18
Abstract: Faulted bipolar transistors in a voltage source transistor inverter are protected against shootthrough fault current, from the filter capacitor of the d-c voltage source which drives the inverter over the d-c bus, by interposing a small choke in series with the filter capacitor to limit the rate of rise of that fault current while at the same time causing the d-c bus voltage to instantly drop to essentially zero volts at the beginning of a shootthrough fault. In this way, the load lines of the faulted transistors are effectively shaped so that they do not enter the second breakdown area, thereby preventing second breakdown destruction of the transistors.

Patent ES-8703394-A1 (ES)
Title: Stable ammonium nitrate-emulsion explosives and emulsion for use therein.
IPC: C06B47/14
Filed: 1984-05-09
Abstract: Explosives that are sensitized blends of a water-in-oil emulsion and AN particles, such as AN or ANFO prills, have improved stability when their structure hinders the loss of water from the aqueous emulsion phase and transportation of such water across the oil phase to the AN particles. Use of an anionic emulsifying agent comprising a fatty acid salt, e.g., as formed in situ during the formation of the emulsion, is the preferred way of forming such a blend-stabilizing structure. Emulsion/ANFO and emulsion/AN blends stabilized in this manner make satisfactory storage-stable packaged products. Emulsion/AN blends made with a new low-viscosity emulsion containing essentially all of the oil required to oxygen-balance the blend and a proportionately larger amount of anionic emulsifying agent to stabilize the emulsion structure constitute preferred bulk products owing to their greater adaptability to pumping. Pumping the stabilized blends through an annular stream of aqueous lubricating liquid is advantageous.

IPC: F01L13/06
Filed: 1985-05-31
Abstract: Process and apparatus for the compression release retarding of a multi-cylinder four cycle internal combustion engine are provided. The process provides a compression release event for each cylinder during each revolution of the engine crankshaft.

The intake valves are opened after each opening of the exhaust valves. The apparatus includes hydraulic means driven by the engine pushtubes which produce a timed hydraulic pulse adapted to open the exhaust and intake valves at the proper time. Hydraulically actuated means are provided to disable the valve crosshead or rocker arm so as to inhibit the normal motion of the valves. Alternatively, timed signals from an electronic controller actuate solenoid valves to control a hydraulic pulse which opens the valves. Solenoid means may also be provided to open the valves mechanically.
