Title: Means for taking up longitudinal expansion and contraction in pipe-lines
IPC: F16L27/12
Filed: 1982-03-05
Abstract: A length of the wall of a pipe (1) is corrugated to form a bellows (2). An anchoring element (3) is fastened to the pipe on one side of the bellows, and a sliding sleeve (4) connected to the anchoring element (3) is arranged on the pipe on the other side of the bellows. The sleeve (4) forms around the pipe, at the respective end of the bellows, an annular space (8) of a cross-sectional area corresponding to the inner cross-sectional area of the pipe and in communication with the inner space of the pipe (1). The pressure in the annular space (8) will be taken up by the anchoring element (3), due to which, the force acting against the bellows in the annular space will counterbalance the same force in the pipe which strives to straighten the bellows. <IMAGE>

Title: Improved unit reject system
Inventor: SIEVERIN WALTER J
IPC: B65G47/50
Filed: 1982-03-09
Abstract: In an apparatus for the rejection of a single container from a row of multiple closely spaced containers 12 on a moving conveyor, a control circuit supplies a signal to a reject mechanism 35 e.g. a solenoid actuated air blast, to remove the container accurately. The circuit has a shift register 40 having a data input indicating a container to be rejected. Its output is combined with blanking signals in a first gate 47. When the container to be rejected reaches the reject station it is detected by sensor 63 which supplies signal to a second gate 69. If this signal and signal 65 arrive simultaneously at the gate 69 the reject mechanism 35 is operated. Mechanical fine tuning is provided to enable positioning the container signal within the appropriate time window. <IMAGE>
