  • Patent number: 11220020
    Abstract: The present invention is a blowing device to be used in interleaver machines for cold cuts. This blowing device enables the plastic used in interleaving, responsible for separating the cold cuts, to be very thin, not folding or being mispositioned, since the device generates negative pressure between the cold cut slice and the plastic.

  • Patent number: 11213967
    Abstract: An apparatus includes channel assemblies in a rotatable section, a cutting assembly, a discharge assembly, and a cleanout assembly. The channel assembly holds a bulk instance of compressible material extending through upper and lower channels of a continuous channel. The cutting assembly moves in relation to the channel assembly to isolate the upper and lower channels, severing upper and lower material portions of the bulk instance. The discharge assembly directs gas into the lower channel of a channel assembly to discharge the lower material portion from the lower channel, based on radial alignment of a conduit assembly of the channel assembly with a conduit assembly of the discharge assembly. The cleanout assembly supplies a fluid through the conduit assembly of the channel assembly, based on radially alignment of the conduit assembly of the channel assembly with a conduit assembly of the cleanout assembly.

  • Patent number: 11207756
    Abstract: Systems and methods are provided for an electric tool (e.g., a power tool) that includes an output driver for receiving an accessory, and an accessory-type detector. A motor of the electric tool is coupled to the output driver for driving the accessory. The power tool also includes an operation trigger for activating the motor and a motor controller. The motor controller includes an electronic processor that is coupled to the accessory-type detector, the motor, the operation trigger, and a memory. The memory stores instructions that when executed by the electronic processor cause the motor controller to detect a characteristic of the accessory from output of the accessory-type detector. The motor controller determines an operational characteristic for the accessory based on the detected characteristic, and controls operation of the motor to drive the accessory according to the operational characteristic when the operation trigger is activated.

  • Patent number: 11203109
    Abstract: An ergonomic cooktop scraping utensil has a planar body, a first side support, a second side support, a blade, and a handle. The blade is removably attached to a distal end of the planar body, and the handle is laterally connected between the upper ends of the first and second side supports. When force is applied to the handle, it is transmitted to the side supports and into both the proximal and distal ends of the utensil. The blade is configured to be oriented at a specified blade angle relative to the cooktop surface for efficient scraping action. The handle is designed to be operated by the heel of the palm of the user in order to minimize any moment arm, and thus strain, applied to the wrist of the user.
