Patent number: 7874505Abstract: A grinder (30) has a toolessly attached ingredient hopper assembly (50) overlying a toolessly attached fixed grinding burr (134) defining the top of a grind chamber (158) within which is received a mating rotary grinding burr (150) that is slidably mounted to a rotary drive motor (154) for adjustment relative to the fixed grinding burr (134). Adjustment is achieved automatically by control of a stepper motor (168) that pushes on the end of an elongate member (151) passing through a hollow rotary drive axle (152) and carrying the rotary grinding burr (150) at an opposite end.Type: GrantFiled: August 29, 2008Date of Patent: January 25, 2011Assignee: Food Equipment Technologies Company, Inc.Inventor: Zbigniew G. Lassota

Publication number: 20100327091Abstract: Safety systems and methods are disclosed for controlling operation of office equipment, such as a paper shredder. In one example, the method includes enabling operation of an electric motor configured to drive at least one moveable component of an electronic office appliance. Upon detection of human motion within a prescribed safety zone defined by at least one passive infrared (PIR)-based motion detector during operation of the electric motor, the electric motor is disabled. In one example, the electronic office appliance includes at least two PIR-based motion detectors positioned near at least one moveable component of the electronic office appliance. Operation of the electric motor can be resumed after a predetermined time interval has elapsed without the detection of subsequent human motion within the prescribed safety zone.Type: ApplicationFiled: June 24, 2009Publication date: December 30, 2010Applicant: TECHKO, INC.Inventor: JOSEPH Y.

Publication number: 20100327093Abstract: A crushing and reducing device, especially cone crushers, used in the building and ore-dressing industries. A method of controlling the operation of a cone crusher having an internal cone connected to an unbalanced vibrator, and an external cone. The method includes utilizing a measurement plane being connected to the internal cone, measuring distances between the measurement plane and a frame of the crusher, and calculating an angle of inclination of the inner cone. The method further includes controlling, based on the calculated angle of inclination of the inner cone, at least one parameter chosen among: the angle of inclination of the inner cone, and the size of a discharge gap between the internal cone and the external cone.Type: ApplicationFiled: September 13, 2010Publication date: December 30, 2010Applicant: SANDVIK INTELLECTUAL PROPERTY ABInventor: Konstantin Evseevich BELOTSERKOVSKY

Patent number: 7850103Abstract: A crusher system includes a gyratory crusher, which has a crushing head, on which a first crushing shell is mounted; a frame, on which a second crushing shell is mounted; and a driving device, which is arranged to cause, by means of a rotating eccentric, the crushing head to execute a gyratory movement for crushing material. The crusher system includes a device for generating a signal that indicates the current tendency of the crushing head to spin; a device arranged to establish, based on the signal, a maximum allowable rotational speed for the eccentric; and a device arranged to adapt the rotational speed of the eccentric to a rotational speed that is lower than the maximum allowable rotational speed.Type: GrantFiled: May 29, 2009Date of Patent: December 14, 2010Assignee: Sandvik Intellectual Property ABInventors: Bengt-Arne Eriksson, Johan Gunnarsson

Publication number: 20100294865Abstract: A system for destroying a memory device (e.g., a hard drive) having data stored thereon. The system has a grind chamber with a rotatable grind wheel positioned therein. A pressure arm presses the memory device against the grind wheel as the grind wheel rotates. The rotating grind wheel grinds the memory device into particles from which the data stored on the memory device cannot be recovered. The particles are collected in a receptacle adjacent the grind wheel. The system may include a plurality of guides configured to maintain the memory device in a substantially stationary position relative to the pressure arm as the grind wheel grinds the memory device into particles.Type: ApplicationFiled: May 21, 2010Publication date: November 25, 2010Inventor: Scott Anthony Wozny

Publication number: 20100288861Abstract: A shredder includes a housing having a throat for receiving at least one article to be shredded and a shredder mechanism received in the housing. The shredder mechanism includes a motor and cutter elements, and enables the articles to be shredded to be fed into the cutter elements. The motor is operable to drive the cutter elements so that the cutter elements shred the articles into shredded particles. The shredder also includes a plurality of sensors provided along the throat for sensing articles. A controller is coupled to the motor and the sensors, the controller being configured to perform a predetermined motor control operation of the motor responsive to the sensors sensing the articles inserted into the throat at an angle above a predetermined angle threshold or the sensors sensing with a predetermined sensing pattern the at least one rectangular sheet of paper inserted into the throat.Type: ApplicationFiled: May 15, 2009Publication date: November 18, 2010Applicant: Fellowes, Inc.Inventors: Qingcheng CAI, Michael D.
