Abstract
Abstract A propelling arrangement for self-propelled oil and garbage skimmer craft having a collecting receptacle, comprises a water jet and a duct for taking in water and delivering it to the water jet. The intake hole of the duct is located below the means for water inflow to the collecting receptacle of the skimmer craft, due to which a water stream entering the duct draws in the upper layer of water together with floating impurities towards the means for water inflow to the collecting receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
A propelling arrangement for self-propelled oil and garbage skimmer craft having a collecting receptacle, comprising: a water jet; a duct for taking in water and delivering it to said water jet; an intake hole of said duct located below the means for water inflow to said collecting receptacle, due to which a water stream entering that duct induces drawing in the uPper layer of water together with floating impurities towards said means for water inflow to said collecting receptacle.
Claim 2
Dependent Claim
79 words
A propelling arrangement for self-propelled oil and garbage skimmer craft having a collecting receptacle, comprising: a water jet; a duct for taking in water and delivering it to said water jet; an intake hole of said duct located below the means for water inflow to said collecting receptacle, due to which a water stream entering that duct induces drawing in the uPper layer of water together with floating impurities towards said means for water inflow to said collecting receptacle.
Claim 3
Dependent Claim
114 words
An arrangement as claimed in claim 1, wherein provision is made for: a substantially vertical ejection passage; an overflow weir installed in said ejection passage in the approximately vertical position and dividing it into two approximately equal parts with one of them communicating with said collecting receptacle and the other - with said duct for taking in water and delivering it to the water jet; the upper edge of said overflow weir located at a height corresponding to the predetermined level of water in said collecting receptacle, whereas with the water jet operating, water is being drawn off said collecting receptacle through said ejection passage to obtain the predetermined water level in the receptacle.
Claim 4
Dependent Claim
54 words
An arrangement as claimed in claim 2, wherein provision is made for a throttle installed in said duct for taking in water and delivering it to the water jet, upstream of said ejection passage in the direction of water flow in said duct, to control the intensity of drawing water off said ejection passage.
Claim 5
Dependent Claim
76 words
An arrangement as claimed in claim 1, wherein said duct for taking in water and delivering it to the water jet has a hole near the water jet to communicate said duct with the surrounding water, and a shutter which in its one position closes said hole in said duct while in the other position it closes the cross-sectional area of that duct upstream of said hole in the direction of water flow in said duct.
Claim 6
Dependent Claim
76 words
An arrangement as claimed in claim 2, wherein said duct for taking in water and delivering it to the water jet has a hole near said water jet to communicate said duct with the surrounding water, and a shutter which in its one position closes said hole in said duct while in the other position it closes the cross-sectional area of that duct upstream of said hole in the direction of water flow in said duct.
