摘要： An apparatus for immersing and agitating objects in a degreasing bath has a tray on which the objects are placed, a supporting structure for the tray and a mechanism driven uni-directionally and incorporating a catch or latch element which is rendered inoperative to impart one motion to the tray and which is engaged to change the motion of the tray into one of a different speed and amplitude. As shown, the tray 7 is supported from lever 1 pivoted at 2 to the main frame of the device, and the crank means 10 imparts a reciprocating motion to the arm 1 through the lever 12 which has a catch 12b engaging pin 13. The tray will reciprocate with a fairly large amplitude and speed. The second lever 8 will engage the pin 11 only when the lever 1 is at or near its lowest point, when the lever 8 will take the weight off pin 13 allowing the spring 14 to disengage the catch arrangement; thus the tray will be subjected to a reciprocating motion of smaller amplitude and speed. In operation, the objects are placed on the tray when it is at its highest point and the machine is set in motion with the catch on. The objects are quickly immersed and then agitated in the liquid until such time as the operator re-engages the catch 12b using handle 12a. The tray is then lifted clear of the bath and limit switch 16 cuts off the motive power at the highest point of the movement. Other embodiments are described and illustrated.

摘要： 587,988. Separating solid materials. KEIGHLEY LABORATORIES, Ltd., and MILLER, C. P. Nov. 24, 1944, No. 23393. [Class 117] In purifying material such as used case hardening or carburising compound the material is sucked up a pipe 6 and the fines pass through a sieve 8 while the undesired heavy material passes through a hole 9 in the apex of the sieve the remaining material being removed by suction up a pipe 10 adjacent the hole. This latter material then passes through one or more sieving processes. In the example shown the good material collects in hopper 2 whereas the dust passes through sieve 15 and fan 13 to a dust extractor 14.
