Patent number: 6120024Abstract: A ball drawing apparatus for drawing a series of balls at random includes a transport arrangement (10) for receiving the series of balls (15) and positioning each ball in a reading position. Each ball (15) includes a transponder (46) which is adapted to transmit an identifying signal when energized by an energizing signal. The identifying signal may be used to identify the particular ball (15) and provide a number or other symbol which is printed on the ball. A reader unit (12) includes a transmitter/receiver (41) and antenna (25) combination which transmits the energizing signal to each ball (15) as the respective ball passes through the reading position, and then receives the resulting identifying signal transmitted from the respective ball transponder (46). The transmitter/receiver (41) communicates the identifying signal to a control system (14) which displays the symbol of the identified ball. Control system (14) controls the operation of all elements of the ball drawing apparatus.Type: GrantFiled: March 19, 1999Date of Patent: September 19, 2000Assignee: Multimedia Games, Inc.Inventor: Jefferson C.

Patent number: 6054164Abstract: A manipulating apparatus (10) receives a plurality of previously frozen pieces of foodstuffs or workpieces (23) and physically manipulates or stresses the workpieces while they remain in a frozen state. The physical manipulation causes relative movement between various points within the volume of the workpieces (23) and kills microbes within the foodstuff. One preferred manipulating apparatus includes a pair of spaced apart, ridged rollers (24,25). The rollers (24,25) have a minimum clearance less than an initial thickness of the workpieces (23). A drive arrangement (30) drives the rollers (24,25) in counter-rotating fashion toward each other to pull workpieces (23) through the minimum clearance area. As the workpieces (23) pass between rollers (24,25), the workpiece material spreads out laterally and bends between opposing ridges (38). This lateral spreading and bending produces relative movement throughout the volume of the workpieces (23).Type: GrantFiled: September 1, 1998Date of Patent: April 25, 2000Inventor: Eldon Roth
