Abstract: A centralised lubrication system and method lubricates cylinder faces in large diesel engines, particularly marine engines. At least one lubricating apparatus has a rotating control shaft preferably running synchronously with the engine main shaft. To make a system that does not have a mechanical drive between the lubricating apparatus and the main shaft, the system is constructed with an AC motor driving the control shaft. Reference means are provided in association with the main shaft, indicating the angular position of the main shaft, and sensor means detect the position of the reference means. The system includes a control unit receiving signals from the sensor and detecting angular position as well as angular speed of the reference means and the main shaft. The control unit is connected with and controls the AC motor (36) for regulating the rotation of the control shaft (18) and thereby actuation of reciprocating pumps providing the cylinder lubrication.

Abstract: Vibration equipment includes a vibration table with rotating shafts for producing vibrations and used in casting concrete blocks for e.g. paving and erection of walls. These vibration tables are normally made of cut-out, welded steel parts that after welding constitute the main part of the vibration table, making such vibration tables costly and resulting in relatively great waste of material. This method solves the above problems by providing vibration equipment in which individual parts for the vibration table are cast in one piece or are welded and are finally fastened to each other by bolts or by welding, thereby avoid several work operations and saving material in the form of steel. Simultaneously, the vibration table is designed such that force and stress flow in the vibration table is optimized.

Abstract: Solar collectors heat and self pump heat transfer fluid at reduced system pressure without mechanical intervention for heat exchange with hot water in a storage tank. Slugs of hot fluid are pumped by steam bubbles formed in solar collector tubes through an upper manifold and an exit-tube into an upper hot fluid reservoir. Hot fluid flows downward through a heat exchanger at the tank. Cold fluid returns to a lower reservoir. Vapor flows from the upper reservoir and is condensed by cooler water and walls of the lower reservoir. The cool fluid returns from the lower reservoir to a lower manifold supplying the collector tubes. Below ambient pressure is automatically established in the system. When heat build-up increases pressure in the system, fluid flows to a third closed variable volume reservoir. A float valve in the bottom of the third reservoir allows liquid to return to the system when it cools.

Abstract: A spray head with improved distributor body for a high pressure spray cleaning apparatus is provided. The spray head is carried on the end of a hand held wand with control valves to separately regulate flow through a pair of fluid circuits, the spray head having a nozzle that sprays heated water in a fan-like pattern against a deflecting edge of a distributor body. Cleaning chemicals are forced through an aperture into the fan-like pattern prior to its striking the deflecting edge to be intimately mixed with the heated water to produce a mixture that strikes the deflecting edge and is deflected therefrom in a highly concentrated form at a high velocity. An elbow guard provides improved protection for the chemical cleaning fluid flow line where it connects to the spray head. Also disclosed is a spray head that allows for the separate application of fluids delivered from separate supply sources.

Abstract: Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable.

The reinforcement material bridges the gap between separated silver flakes in the conductive silver ink. The carbon nanotubes reinforced conductive silver ink exhibits superior performance over unreinforced silver ink in its mechanical, electrical and thermal properties without significantly greater weight.

Abstract: Thermal processing of recycled asphalt pavement (RAP), having up to approximately 8% or more moisture content, dries and preheats the material to enhance efficient recycling in a hot mix asphalt plant. A combustor and heat exchanger reheat circulating hot oil, which with hot gas, moves through a hollow auger and around the RAP counter to the flow of RAP. Moisture is forced outward from within the particles and is flashed away by the hot exhaust gas. A similar secondary heater heats the RAP to just below asphalt coking temperature before the hot dry RAP is added as an aggregate to the hot mix asphalt plant.

Abstract: A gas operated part forming die apparatus has compact high tonnage presses which are operated by high pressure gas generated within chambers and controlled to operate high pressure pistons and dies for compressing particulate material into dense formed parts. Combustion chambers are filled with pressurized mixtures of combustible gases and diluents. Elongated chambers have insulating walls and spaced electrodes. Some contain liquid or particulate ablatable materials or ablatable liners. Others extend fuzes between the electrodes and are filled with pressurized gases. Gas is removed from the particulate material. Die cavities may be precompressed during filing of chambers with pressurized gas. Igniting the combustible gases or creating arcs between the electrodes produces rapidly expanding high pressure resultant gases for driving pistons and movable dies and rapidly compressing die cavities. Pressures in the chambers are contained, or pistons are restrained until releasing and driving the pistons.

Abstract: The new invention allows for easy retrieval of fall backs and eases the initial threading process upon initial opening/use of the package. Threading is done without removing the cap. Several of the embodiments allow refills to be inserted into the canister without removing the lid/cap. The layout of the dispensing system and the geometry and shape of the dispensing orifice/aperture minimize and mitigate product fall backs. The new invention improves performance of the orifices/apertures through unique geometry and shape as well as using different materials from existing products or the combination of multiple materials. Varying orifice diameter, co-molded density and stiffness or geometry of the actual lobes defining the dispensing aperture allows the precise amount of friction to be created in the dispensing opening for selectively grabbing or releasing the towelette, thereby tearing the towelette connecting perforations at just the right time.
