  • Publication number: 20220304320
    Abstract: A traditional method for making, pasteurizing and packaging preservative-free, fresh food product comprising chickpeas, such as hummus, that involves a continuous process in which the temperature does not deviate more than 50° C. from the cooking step until just prior to packaging. In one embodiment, the method comprises cooking the chickpeas from 110° C. to 125° C. while under pressure, which is followed by adding raw ingredients to the cooked chickpeas at a temperature ranging from 75° C. to 85° C., which is immediately followed by a pasteurization at approximately 75° C. Only after this pasteurization step is the temperature reduced in a multi-step cooling process. The as-made, fresh and preservative-free food product comprising chickpeas, such as hummus, is packaged into containers by transferring the finished food product that is maintained at a temperature ranging from 5° C. to 10° C.

  • Publication number: 20220257244
    Abstract: A shell assembly includes a shell housing defining a cavity, a plurality of staples, a staple cartridge supported on the shell housing, a pusher assembly positioned within the cavity of the shell housing, and a hydraulic piston configured to engage the pusher assembly to impart axial displacement to the pusher assembly and form a fluid tight seal against the shell housing. The staple cartridge defines slots that receive the plurality of staples. The pusher assembly includes a plurality of pushers arranged in an annular configuration to eject the plurality of staples from the staple cartridge. Supply of a fluid into the cavity of the shell housing advances the hydraulic piston, which, in turn, advances the pusher assembly to eject the plurality of staples from the staple cartridge.

  • Patent number: 11406383
    Abstract: A handle assembly includes a trigger assembly, a motor, and a drive assembly. The trigger assembly includes a trigger, a head portion, and a deflection member interconnecting the trigger and the head portion such that a load applied to the trigger causes the deflection member to flex to define a gap between the trigger and the head portion. The motor is configured to be activated based on a size of gap defined by the trigger and the head portion. The drive assembly includes a clamping gear, a firing gear assembly, a drive gear, and a rack. When a button of the trigger assembly engages the clamping gear, actuation of the trigger advances the rack by a first distance, and when the button engages the firing gear assembly, actuation of the trigger advances the rack by a second distance greater than the first distance.

  • Patent number: 11389144
    Abstract: A surgical system includes an intelligent surgical device having a drive motor supported in the housing and being in electrical communication with the power source; and control circuitry. The control circuitry includes a feedback system for monitoring a condition of the surgical device during a use thereof and for changing an operative parameter of the surgical device when a change in the monitored condition occurs. The surgical system includes a non-intelligent loading unit for selective connection to the housing of the surgical device and which is actuatable by the drive motor, the loading unit having a first and a second condition. During operation, the drive motor actuates the loading unit from the first condition to the second condition; and when the loading unit achieves the second condition, a change in the at least one monitored condition occurs and an operative parameter of the surgical device is changed.
