Abstract: A machine and method wherein a pusher advances a piece of meat to be sliced across the plane of a slicing blade against a backstop. The blade removes a slice from the piece. The difference between the slice weight and a preselected reference weight is used to adjust the separation of the backstop from the plane of the slicing member and hence the thickness of the next slice to be cut from the piece so as to tend to closely conform the weight of the next slice to the reference weight. Clamps hold the piece during slicing but release to allow the pusher to again advance the piece for production of the next slice. The pusher is actuable for ejecting a residual butt portion of the piece to enable loading of a new piece.

Abstract: In a method for determining, by means of an observing and recording measuring device the exact position of a movable member and/or for determining a corrective movement to be performed from a position of the member, a measuring device having a datum position is used. The method includes the steps of determining the position of the movable member and/or a required corrective movement thereof by moving the measuring device past the position of the movable member and determining a new position obtained through the corrective movement or, alternatively, re-determining the first mentioned position of the movable member by moving the measuring device a second time past the movable member in an opposite direction.

Abstract: A portable hand operated bagel slicing machine which slices or preslices bagels quickly, evenly and safely. Eliminating the hazards of slicing bagels in Bagel Bakerys, Restaurant, and Homes. It's light weight and will fit most kitchen work areas. It preslices a bagel by leaving a space in the center of the two blades. This leaves a small strip of dough through the middle of the bagel. The bagel halves stay together and can easily be separated later. Blades in the device are adjustable so one can achieve any degree of horizontal slicing. Jamming of the pusher from residue is prevented by a recess under the pusher. Slicing a bagel with the device is achieved by placing the device on the edge of a convenient table, counter, or cutting board. Insert a bagel in the top opening. Push the handle forward. The bagel exits the front of the device sliced.

Abstract: The alignment of the drill stem and bit of a rock drill rig is corrected when the force of drilling and the feeding power on the drilling machine of the rig has resulted in a change in the direction of the drill stem because of deformation of the articulated and extensible drill boom of the rig and of its pivotally supported drill support on the drill boom. The drill rig is of the type that includes elements for measuring boom lengths and articulation angles, servos for controlling such lengths and angles and a control unit which is connected to the measuring elements and servos for adjusting the drill stem and bit. The various articulation angles which are required to compensate for deformations of the drill boom and drill support are determined as if the drill boom and support were in an unloaded condition, on the basis of measured values of the boom lengths and articulation angles which have been registered in the control unit in an unloaded condition.
