Automatic cleaned drain piping system on crosshead type two-stroke engines. The invention is having a slow rotating centreless flexible spiral auger fixed mounted in the piping system.

A ball lifting device of the present disclosure, which employs a spiral ball transporting method for smoothly moving a ball, can move along a free path, is easy to be installed and operated, and has excellent durability and strength. The ball lifting device can be installed indoors as well as outdoors for educational, entertainment or viewing purposes. The ball lifting device can quickly move inflated balls filled with air used in ball games, and can be installed in connection with sports facilities as an automatic ball supply system.

Automatic cleaned drain piping system on crosshead type two-stroke engines. The invention is having a slow rotating centreless flexible spiral auger fixed mounted in the piping system. The purpose of the invention is to constant avoiding build-up of deposit inside the drain pipes during normal operation. My invention will prevent partly or full blockage of the drain piping. The invention will help to trouble free, reliable and safe continued operation of two-stroke crosshead type engines. The invention will give dramatic savings in man-hours, cleaning chemicals and materials used during manual pipe cleaning. The invention is suitable for mounting during construction of new engines as well as for retrofit. The purpose of the very slow rotating auger is solely to keep heavy, solid and slow flowing particles moving along with the freely flowing oil, thus avoiding deposit building up inside the pipe. The slow rotation speed of the auger inside the pipe creates a scraping action on the lower part of the pipe inner wall, thereby keeping heavy, solid and slow flowing particles in motion.

A weighing apparatus for weighing batches of food product is provided. The weighing apparatus comprises a product supply unit arranged to supply food product to be weighed, a weighing unit arranged to receive and weigh a batch of food product, and a product delivery unit arranged to receive the food product from the product supply unit and to deliver a batch of food product to the weighing unit. The product delivery unit comprises a trough extending between a product supply position, at which food product is received from the product supply unit, and a product delivery position, at which the food product is delivered for receipt in the weighing unit, and a transport screw arranged in the trough and configured to rotate in the trough for conveying food product from the product supply position to the product delivery position. The transport screw comprises at least two helical members. A primary helical member extends along a length of the trough substantially from the product supply position to the product delivery position. A secondary helical member extends along a length of the trough substantially from the product supply position to a termination position of the secondary helical member, the termination position of the secondary helical member being between the product supply position and the product delivery position.

An improved feeder/conveyor includes a flexible rotating open helix screw inside a cylindrical sheathing. A motor drive is attached to the flexible rotating open helix screw above at a delivery end, and such provides the rotational speeds necessary to generate the centrifugal and lifting forces necessary. The improvements include a conical bullnose tip as a feeder that attaches to the flexible rotating open helix screw with a curved and tapered support feeder gusset. Such attachment mechanically supports and aligns the conical bullnose tip to the distal end of the flexible rotating open helix screw and a central turning axis. A nose opening in the conical bullnose tip allows either exit or entry of material freely to or from the supply bed, depending on the conveying conditions.

A device for conveying and feeding containers, for machines for processing containers, which device includes a conveyor for movement of containers along an advancement direction, and separation system, which is adapted to mutually space apart the containers along the advancement direction. The separation system includes a screw feeder and at least one abutment wall, which is arranged so as to face to the lateral surface of the screw feeder. The screw feeder has, along its longitudinal extension, proceeding from one of its ends to the other end in the same direction as the advancement direction of the containers, three regions that can be engaged in sequence by the containers, respectively at least one access region for the containers, at least one accommodation region, which is adapted to receive one container at a time from the access region, and an acceleration region for accelerating the containers.
