Abstract: A mill comprises a casing having an opening for supply of material to be milled and a rotor rotatably supported in the casing and provided with cutting members (3) for disintegrating action on the material. The cutting members (3) are arranged in a plurality of sets (4a-d) distributed about the periphery of the rotor, and having an axial extent (arrow 33). At least two of the sets (4) have their cutting members (3) mutually displaced in axial direction.

Abstract: This impact dampening system for a vending machine chute includes a resilient sheet disposed above a fixed support and a cushioning arrangement disposed between the resilient sheet and the fixed support. In one embodiment, a sheet metal chute provides the fixed support and a sheet plastic chute having a similar configuration to the sheet metal chute provides the resilient sheet, and foam pads between the two chutes providing the cushioning arrangement for containers received by the plastic sheet. In another embodiment, a sheet plastic chute only is used which is suspended by hangers or attached by brackets to the vending machine and may be provided with a diverter to direct containers away from direct travel to the vending machine access port.

Abstract: A water shut-off system incorporates a water shut-off valve utilizing a pair of adjacently disposed electrodes, a transmitter and a receiving means. The water shut-off valve is in the form of a ball valve. A timing logic causes current to flow to a valve driving motor as electric pulses.

Abstract: This oil level control device is for a refrigeration system, the control device being attached between the compressor and the oil supply. The control device includes a housing having an inlet communicating with the oil supply and an outlet communicating with a compressor sump; and a solenoid valve controlling flow from the oil supply into the compressor sump. A sensing chamber having a fixed probe providing a proximity detection system detects the oil level in the sump and responds to a change in the complex permittivity of the oil as the oil level rises and falls to generate a signal that controls the supply of oil to maintain the oil level in the compressor. Circuitry is provided having an input connected to the output of the sensor and an output connected to the solenoid valve.

Abstract: This bill validator (10) includes a bill inlet area (30) defined by opposed upper and lower surfaces (24, 26) and having a magnetic read head (50). A pressure device (60) is provided below the magnetic read head (50) and urges a bill B received by the inlet (30) toward engagement with the read head to press the bill into engagement with the read head and assist in moving the bill in the direction of travel of the transport system (21).

Abstract: In offset presses in which the printing cylinder is provided with a tensioning spindle or reel rod the printing plate usually has a hooked edge which is inserted in a gap in the printing cylinder. The printing plate is then wrapped around the plate cylinder for insertion in the spindle within the plate cylinder. The tensioning spindle carries a slot for receiving an end of the printing plate. After insertion of the plate end in this receiving slot partial rotation of the spindle tightens the printing plate. A substantial amount of skill is required to fix a printing plate on a printing cylinder. It is not easy to align the gap in the printing cylinder with the slot in the tensioning spindle. Two hands are usually required. Herein the tensioning spindle end shaft carries a pinion capable of moving a rack associated with it when the tensioning spindle is partially rotated. A spring is installed to oppose the rack movement.

Abstract: Telescopic stands for articles such as microphones used by entertainers, hospital intravenous packets and cameras are widely used. Some telescoping microphone and hospital intravenous stands require many turns of a ring in order to hold the microphone, for instance, in place. An entertainer needs to be able to almost instantly adjust the height of his microphone. The stand herein includes a height adjusting means which operates more quickly. It includes telescopically related outer and inner members, and also means for readily locking the upper inner member within the lower outer member.

Abstract: This binder (10) includes a front cover (12), a rear cover (14) and a spine (16) and is provided with a transparent label holder (50) which extends across the spine (16) and is attached to at least one of the covers (12,14). The label holder (50) provides an open upper margin (52) and is attached at the side margins (60, 62) and at least partially attached at the lower margin (54) to retain the label (100) which thereby has an increased area for label information.

Abstract: This refrigerator unit (10) with a lighted door (20) includes a cabinet (12) defining a front opening (18). The door (20) is mounted to the cabinet (12) and includes a door frame (22) having top and bottom framing members (26 and 28) and side framing members (30 and 31). A lighting assembly (100, 200) is disposed adjacent one of the side framing members (30), and includes a base member (102, 202) which extends between the top and bottom framing members (26, 28) and conceals the lighting (134, 234) from sight outside of the refrigerator unit (10).

Abstract: This indexing system (10) for use with a binder (12) includes a plurality of section divider sheets (14) each having an outstanding tab (16) with index indicia thereon and a foldout index sheet assembly (18). The assembly (18) is formed from a unitary foldable sheet which includes a carrier portion (20) and a foldout index portion (22) provided with index indicia corresponding to the indicia on the tabs.
