Title: Oil burners
IPC: F23L7/00
Filed: 1979-04-19
Abstract: This invention relates to a process for increasing the combustion effect in an oil burner. According to the process, a mixture of oil, atmospheric air, and added oxygen is projected through a jet into the combustion chamber of the oil burner at a pressure several times greater than 0.5 atmospheres, the outflow aperture of the jet having a diameter which is in the region of 1/10 to 2/10 mm. Because of the high pressure, a stream which is power-charged and enriched with considerable oxygen and by which combustion is advantageously influenced and oil consumption reduced, leaves the jet. Atomization is advantageously effected at a pressure of 2 atmospheres.

Title: Load handling apparatus
IPC: H01Q1/12
Filed: 1980-01-15
Abstract: A vehicle 1 is required to carry an antenna 5 and to raise it from a withdrawn position (not shown) where it is clear of any overhead obstructions during motion of the vehicle to an elevated position as illustrated where its field view is unobstructed by its own lifting mechanism 8. Problems were encountered in designing a lifting mechanism capable of moving the antenna between these two extremes. The problem is overcome by using a carrier 1 which is moved up and down guides 12 by a shaft 24. The carrier 11 itself carries a table 10 on which the antenna is mounted and this table 10 can be moved by crank mechanisms from the top of the carrier 11 to the bottom of the carrier 11 to ensure that the antenna is clear of the carrier 11 in its elevated position and yet can be lowered almost to the floor of the vehicle when in its withdrawn position. <IMAGE>

Title: Making microfilaments from blown film
Inventor: TOROBIN LEONARD B
IPC: D04H13/02
Filed: 1982-11-26
Abstract: Relatively long plastic microfilaments made from a plastic composition. The plastic microfilaments may be used to make reinforcing, filler materials and fabrics. The microfilaments are made by forming a liquid film of plastic across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure on the inner surface of the plastic film to blow the film and form an elongated hollow tube or cylinder shaped liquid film (12) of plastic. Means are provided for forming a thinned wall or weakened portion of the plastic film forming the wall of elongated tube or cylinder. A transverse jet (13) is used to direct an entraining fluid (14) over and around the blowig nozzle (5) at an angle to the axis of the blowing nozzle. The entraining fluid (14) as it passes over and around the blowing nozzle (5) fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube or cylinder. The continued movement of the entraining fluid (14) over the elongated tube or cylinder (12) produces asymmetric fluid drag forces on the tube or cylinder, and at the thinned walled or weakened wall portion longitudinally breaks the tube or cylinder to form a multiplicity of plastic microfilaments, and detaches the plastic microfilaments from the elongated tube or cylinder and from the coaxial blowing nozzle and the detached microfilaments are carried away from the blowing nozzle.
