Abstract: An online booking system includes a computer connected to a wide-area network, the computer including a processor and a memory configured to store programming and data. An act database includes entertainment records associated with a plurality of entertainers. Programming causes the processor to receive a performance request from a talent buyer over the network, the performance request including performance request data regarding an open performance date desired to be booked. The system determines if the performance request data matches a respective entertainment record in the act database and, if so, notifies a respective entertainer associated with the selected act to contact the buyer. If the act is booked, the processor updates the act and talent buyer itinerary databases. Matching a performance request with entertainment records may include determining if an entertainer is available within a predetermined number of days of the performance date and within a predetermined distance.

Abstract: A pump comprises a plurality of pistons movable in a direction, a swash plate arrangement forming an angle with said direction so as to reciprocate said plurality of pistons in said direction and an elastic element interacting with said swash plate arrangement to enable said angle to be modified. Between said elastic element and said swash plate arrangement a transmission device is interposed for receiving a force from said swash plate arrangement and transmitting a fraction of said force to said elastic element.

Abstract: A motor pump for high-pressure washers having a structure of the type that comprises a rotating plate that is inclined with respect to its axis and on which at least two pistons push, the pistons being arranged parallel to the axis in radially spaced positions. The rotating plate is associated for joint rotation with a motorized support, which is arranged opposite the pistons and on which the plate can oscillate freely in order to vary its inclination, with respect to the rotation axis, between preset values that determine the axial movement of the pistons, elastic elements for contrasting the variations in inclination induced by the pistons being functionally interposed between the plate and the support.
