Printing system with inverter disposed for media velocity buffering and registration

Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

Combined axial piston liquid pump and energy recovery pressure exchanger

A pumping machine, that can serve a system as the sole main pump for pressurizing a primary liquid flow, incorporates, in a single machine, a rotor-drum type AP (axial piston) pump and a PX (pressure exchanger) that recovers energy from a secondary liquid flow such as the brine discharge from an RO seawater desalination system, with benefits including fewer moving parts and small machine size along with lower capital and operating costs. A single rotor-drum containing the cylinders and pistons is located between two end blocks, one or both configured with manifold passageways, ports and sliding valves. A swash-plate at one end reciprocates the pistons axially when the rotor-drum is rotated. Two working chambers, primary and secondary, are formed at opposite ends of a single piston in each cylinder, thus enabling the single rotor-drum to function as a primary liquid-pressurizing axial pump (AP) with sliding valves at the primary end enabling primary liquid pumping, and as a secondary outflow-driven pressure exchanger (PX) recovering energy from pressure drop in the secondary liquid flow and thus contributing work to primary pumping, saving energy and reducing operating costs.

Wireless power supply apparatus, filter unit and power supply apparatus for robot using the filter unit

A wireless power supply apparatus includes a power reception coil, an actual load and an auxiliary load. The power reception coil functions as a repeater for receiving electric power in a non-contact manner by magnetic resonance with a power transmission coil to which electric power is supplied from a power supply unit and relaying transfer of the electric power from the power transmission coil. The actual load is connected to the power reception coil and is powered by the electric power received by the power reception coil. The auxiliary load is inserted parallel to the power reception coil and the actual load and forms a closed circuit with the power reception coil when supply of the electric power to the actual load is interrupted to be in an open state.

Reduced size citrus fruit juicing machine

This invention is a reduced size citrus fruit juicing machine that uses sets of rotating male-female drums characterized by having one sole female drum and one sole male drum with an automatically positioning blade and a retaining pendulum—turning device. These characteristics avoid having to incorporate a second set of drums into the machine since the remaining half of the fruit is turned after the cut into the following upper cavity of the female drum. In addition to maintaining the performance of similar machines of greater size, it improves hygienic conditions due to an appropriate disposition of the retaining pendulum, a ribbed opening for the fruit, a peel collector and an integrated customized juice container which are isolated from the outside, all of which make it especially attractive to hotels and restaurants that do not have much available space.
