Title: Foundry mold-making apparatus
IPC: B22C15/10
Filed: 1970-04-28
Abstract: A jolt foundry moulding machine has a moulding table 12 with a vertically projecting stem 16. The stem 16 is surrounded by a rapper member 24 which moves between an upper position abutting the table and a lower position, to provide jolting. At the lower end of the stem 16 is provided a piston 26 which coacts with a cylinder 28 attached to the rapper member. In operation, pressure fluid is first supplied to ducts 36, 38, 40, 42, 44 to enter a chamber 32 and force the rapper member downwardly to a position limited by ducts 52 which allow the fluid to escape. Simultaneously, the air supply is cut off as the ducts 40, 42, 44 are then out of alignment. Pressure fluid is supplied by a duct 56 to a chamber 30 above the piston 26 and during the downward movement of the rapper member is compressed in the chamber 30. Escape of fluid from the chamber 32 allows the fluid in the chamber 30 to expand, thereby forcing the rapper member 24 upwardly to provide a jolt-strike against the table 12.

Title: Control system and method for concurrent automatic gage and crown control of a rolling mill
IPC: B21B37/38
Filed: 1972-11-03
Abstract: A control system and method for concurrently controlling the delivery gage and crown of a workpiece while it is being processed in a rolling mill, preferably in the form of a 4-high rolling mill including a piston and cylinder assembly type of force applicator for adjusting the gap formed between the working rolls under the rolling load. The rolling mill further includes roll bending apparatus whereby bending forces are applied to extended journals of the backup rolls for changing the effective roll crown at the roll gap. The control system provides an automatic control designed to concurrently maintain a relationship between signals generated on the basis of rolling mill measurements to control the force applicator and the roll bending device. This concurrent relationship of signals equates a position change of the force applicator with the algebraic sum of signals representing roll gap changes due to a change in the rolling load and due to a change in the roll bending force, while concurrently the change in roll crown due to a change in roll bending force is equated to a rolling load change. The control system includes additional circuitry for an alternate form of concurrent gage and crown control.

Title: Stilligout or dropper particularly for infusion apparatus
IPC: A61M5/14
Filed: 1976-08-27
Abstract: A dropper for infusion liquid particularly for connecting an infusion bag to a catheter comprising a dropper housing defining an interior dropper chamber having an inlet connected at the top of the dropper chamber and an outlet tube extending into the chamber on a side opposite from the inlet. A deaeration opening is provided in association with the outlet tube for venting the interior of the chamber when the chamber is inverted into a filling position. The deaeration opening is positioned within the chamber at a level sufficient to define a first air volume bounded by a plane tangent to the deaeration opening and a portion of the dropper chamber above the plane, which volume is smaller than the remaining volume of the dropper chamber. A second volume is defined by a plane tangent to an opening of the inlet within the dropper chamber and a portion of the dropper chamber above the opening. The opening of the inlet is positioned so that the second volume is smaller than the first volume defined by the deaeration opening. When the dropper chamber is returned to an upright position after having been filled in an inverted position the difference between the first and second aforementioned volume provides a safety level of liquid above the outlet tube within the dropper chamber.

Patent ES-461766-A1 (ES)
Title: Material feeding apparatus
IPC: B30B9/30
Filed: 1977-08-19
Abstract: The apparatus has a guide housing (7) with a charging aperture situated at the top, in which housing is provided a substantially horizontally operating conveyor slide (8) with cover plate (12).
