Abstract: ICEMAKER FOR PRODUCING VARIABLY-SIZED SHEET ICE   Abstract: An ice breaking head (64) for an ice producing machine (12) which is adjustable for producing harvested ice of selected sizes. The ice maker has a cylinder (20), the inner surface of which produces commercial sheet ice. The ice is harvested by forcing the ice from out of the cylinder toward the ice breaking head. The position of the ice breaking head is adjustable to vary the size of the ice harvested. The head has an ice breaking surface which contains fins (26) for facilitating the breaking of the ice sheet. It is journalled on a mounting post (70) which has keys or ribs (71) of increasing heights which match corresponding keyway slots (74) in the bore of the head, and hence the size of the ice harvested, can be adjusted by changing the rotational position of the head on its mounting post.

Abstract: ABSTRACT      A groundwater monitoring system includes a bore, a well casing within and spaced from the bore, and a pump within the casing.  A water impermeable seal between the bore and the well casing prevents surface contamination from entering the pump.  Above the ground surface is a removable operating means which is connected to the pump piston by a flexible cord.  A protective casing extends above ground and has a removable cover.  After a groundwater sample has been taken, the cord is disconnected from the operating means.  The operating means is removed for taking away, the cord is placed within the protective casing, and the cover closed and locked.  The system is thus protected from contamination, as well as from damage by accident or vandalism.
