An input conveyor, output conveyor, and knife assembly with a blade between the input and output conveyors all reciprocate back and forth as a blade moves perpendicular to the conveyors to cut portioned sized of product, such as ground meat. The cut cycle allows the product feed to keep moving in a continuous manner on conveyors. For ground meat, this system can allow production rates of 150 pieces or more per minute per conveyor line and can improve the accuracy of portioning. The blade is actuated by a profiled cam set that pulls the blade down, and then returns it with a spring to an upper position. The knife assembly can accelerate just after cutting to reduce the potential for sticking to the cut product. |

Method for producing hyperthermal hydrogen molecules and using same for selectively breaking C—H and/or Si—H bonds of molecules at or on substrate surfaces
A method for producing hyperthermal molecular hydrogen is disclosed and use of same for selectively breaking C—H or Si—H bonds without breaking other bonds are disclosed. A hydrogen plasma is maintained and protons are extracted with an electric field to accelerate them to an appropriate kinetic energy. The protons enter into a drift zone to collide with molecular hydrogen in gas phase. The cascades of collisions produce a high flux of hyperthermal molecular hydrogen with a flux many times larger than the flux of protons extracted from the hydrogen plasma. The nominal flux ratio of hyperthermal molecular hydrogen to proton is controlled by the hydrogen pressure in the drift zone, and by the length of the drift zone. The extraction energy of the protons is shared by these hyperthermal molecules so that average energy of the hyperthermal molecular hydrogen is controlled by extraction energy of the protons and the nominal flux ratio. Since the hyperthermal molecular hydrogen projectiles do not carry any electrical charge, the flux of hyperthermal hydrogen can be used to engineer surface modification of both electrical insulating products and conductive products. When this method of generating a high flux of hyperthermal molecular hydrogen is applied to bombard organic precursor molecules (or silicone, or silane molecules) with desirable chemical functionality/functionalities on a substrate, the C—H or Si—H bonds are thus cleaved preferentially due to the kinematic selectivity of energy deposition from the hyperthermal hydrogen projectiles to the hydrogen atoms in the precursor molecules. The induced cross-linking reactions produce a stable molecular layer having a controllable degree of cross-linking and retaining the desirable chemical functionality/functionalities of the precursor molecules. |

Combination and modified electrolyte to reduce risk of premature lithium ion battery failure, including in aircraft applications
A combined system reinforces the safety of lithium ion batteries by redesign of electrolyte and the charging current a) modifying the electrolyte to inhibit or prevent dendrite growth preferably by the addition of lithiated polyphenoxy polyethylene glycol and/or a second surface active compound chosen from the family of fluorosurfactants, and/or a modest amount of lithium or sodium borate, b) modifying the charging cycle by a so-called ripple current in order to inhibit or prevent dendrite growth (ripple current meaning oscillation in the amount of amperage or voltage in the charging cycle), c) programmable battery management systems with temperature and electrical limits integrated in order to eliminate from the circuit and bypass malfunctioning cells based on past performance of the charging cycle and voltage endpoints achieved, d) minimizing any transient currents and voltages into or out of the battery system and e) maintaining a cool atmosphere in the battery space. |

Power supply device and power supplying method for power supply device
A power supply device includes a battery, a charging part charging the battery, a power input to receive adapter power from an adapter supplied with external power or power output from a similarly configured power supply device, a power output part to output the adapter power, the power output of a similarly configured power supply device, or the battery power of the battery, and a controller to control the input power to apply power to the charging part and the power output part when the input power is supplied to the power input part, and to control the battery to apply power to the power output part when the input power is not supplied to the power input part. Thus, the power supply device is capable of applying power from an adapter to a portable electronic device while charging an internal battery with the adapter power. |
