Abstract: 1465634 Floating booms A GRIHANGNE 19 June 1974 [21 June 1973 2 May 1974] 27210/74 Heading E1H An inflatable boom for containing oil spillage consists of a flexible sheet folded over and joined at the lower end to form a buoyancy chamber 9 at the upper end, with the fabric is joined together at intervals at 10 to make the boom flexible when inflated and to control the buoyancy along the boom's length. Similarly the lower end is weighted by discrete weights 3. A substantial part of the folded sheet may be joined together below the buoyancy chamber to form an apron 13, Fig. 6, and chains or belts 16, 17, may be attached to the apron to strengthen the boom or to enable it to be reeled in onto a ship. The boom is inflated either by blowing air directly into one end of the buoyancy chamber, or by means of a perforated inflation tube 14. The pressure in the chamber may be limited by a series of bellows 21 with an open bottom end 22; the chamber communicates with each bellows by way of an opening 20, so that the pressure in the chamber 9 is limited to the hydrostatic pressure at the bottom end 22 of the bellows 21. The boom may be deflated by allowing air to escape through openings 24 in the top of the flexible sheet. Normally a tube 23 is kept inflated to cover up the openings, but if the tube is deflated, the openings are uncovered. This feature may be used to submerge the boom to allow a ship to cross the boom. The ends of the boom may ride by rings on a column 26-33 e.g. attached to a quay. In this way a ship may be enclosed within the boom while it is loading or unloading.

Filed: 1954-09-21
Abstract: 789,596. Knitting-machines. SCHONFELD, P. Sept. 21, 1954, No. 27287/54. Class 74 (2). The drive for a ways knitting-machine and the mechanism for raising and lowering the guide bars are both controlled by a single operating rod 1 which is ground in such a way that the machine can only be operated after the guide bars have been lowered, and the guide bars can only be raised after the machine has been stopped. The drive for the machine is through an electric motor controlled from a switch actuated by a lever 20 connected to the rod 1. By moving the rod 1 longitudinally the switch is operated to stop or start the machine. The rod 1 is also rotatable and through an eccentric 2 and linkage 010 ... 18 rotation of the rod causes raising or lowering of the guide bars 24. To ensure that the guide bars are lowered before the machine is operated, a key 4 on the shaft 1 engages a keyway 3 in the eccentric 2 and only when the rod is sufficiently rotated to lower the guide bars does the key 4 further line up with a keyway 5 in a stationary bearing 6, thereby permitting the shaft to be moved longitudinally. Similarly, it is necessary to move the rod 1 so that the key 4 disengages keyways 5 and stop the machine before the rod 1 can be rotated to raise the guide bars. A stop 7 on the rod 1 engages a stationary stop 8 on another bearing 9 to ensure alignment of key 4 and keyway 5.
