Patent EP-0284842-A1 (EP)
Inventor: NAGARWALLA PHEROZE J
IPC: B22C15/24
Filed: 1988-03-08
Abstract: A foundry machine for forming molds or cores from a molding material such as sand provides a completely automated operating cycle commencing with loading the separable stacked tooling elements (24) onto an auxiliary table (18). These tooling elements may include, from the top down, a sand magazine (36), blow plate (34), combined gassing manifold and top ejector unit (32), upper mold box (30), lower mold box (28) and bottom stool (26) containing a lower ejector mechanism (390). The tooling is then conveyed along tracks (22, 40) into a mainframe (10), lifted from the tracks (40) by means of a work table (42) which is actuated by a compact telescoping hydraulic cylinder (46), and raised on this work table (42) until the sand magazine engages the blow sleeve (54). The sand magazine (36) is then clamped to the blow sleeve (54) and the blow plate (34) is clamped to the sand magazine (36). A transfer mechanism (68, 70) then engages the gassing manifold and top ejector unit (32), and the work table (42) is lowered to provide clearance for the transfer mechanism (68, 70) and gassing manifold and top ejector unit (32) to be laterally shifted to a stand-by position. Then the work table (42) is raised again to bring the mold boxes (30, 28) up into sealing engagement with the blow plate (34), whereupon sand is blown into the mold box cavities. The work table (42) is again lowered with the mold boxes (30, 28) to allow the transfer mechanism (68, 70) to return the gassing manifold and top ejector unit (32) into position between the upper mold box (30) and the blow plate (28). The work table (42) is raised again to press all the tooling units together against the blow plate (34) for the gassing step, following which upper mold box hangers (76) are swung into position. Upper and lower ejector pins (280, 390) are actuated and the work table (42) is lowered, causing upper mold box (30) to engage and be supported by the hangers (76), thereby separating the mold boxes (30, 28) as the work table (42) and lower mold box (28) continue downward. The completed part (388) is supported on the lower ejector pins (390), and a part-removal unit (78, 100) is transferred along the auxiliary table (18) so that pick-off fingers (100) can enter the gap beneath the ejected part (388), whereupon the lower ejector pins (390)   are lowered to transfer the part (388) onto the fingers (100) for removal by the removal unit (78, 100). The cycle can then be repeated by transferring the gassing manifold and top ejector unit (32) to its stand-by position and raising the mold boxes (30, 28) into their part-forming position.

Abstract: In a process for the pressure-controlled catalytic combustion of flammable gases, e.g. hydrogen or the like, with oxygen in an oxidation reactor, it is proposed that one of two reactants fed into the oxidation reactor is added in excess until the initial pressure (P0) in the reactor has risen to a predetermined excess pressure (P2); that, after reaching the pressure value (P2) addition of the reactant added in excess is blocked for a period of time ( DELTA t1), in which the pressure drops to a value (P1 < P2); that, after reaching the pressure value (P1), the blocked excess reactant is again fed in for such a period of time ( DELTA  t2) that the pressure (P2) is again reached; and that these steps are carried out in succession.

Title: Frame for belt conveyors
Inventor: GEPPERT HELMUT
IPC: B65G21/02
Filed: 1988-11-17
Abstract: The invention describes a frame for belt conveyors, comprising parallel T-grooved longitudinal spars which are located opposite one another at a distance and interconnected in one piece by means of an intermediate support, and the longitudinal spars can have fastened to them bearing plates for deflecting and/or driving rollers. Such a frame should be structurally simple, inexpensive to manufacture and keep in stock, and the fabrication should require minimum machining of the frame. This is achieved if at least one of the two free surfaces of the intermediate support is designed as a continuous sliding plane for the conveyor belt or as a bearing surface for a slide block and if the longitudinal spars each have, in the region of their outer lateral limiting faces and in the vertical position between the two free surfaces of the intermediate supports, a T-groove extending over the entire length.

Abstract: The wheel unit has a housing (1) which is composed of two side wall discs (13, 15) and an essentially U-shaped peripheral wall part (17) and in which a travelling wheel (5) is rotatably mounted on bearing extensions (23, 25) of the side wall discs (13, 15) via rolling bearings (29, 31). The rolling bearings (29, 31) sit in ring shells (33, 35) inside a hub opening (27) of the travelling wheel (5), the bearing extensions (23, 25) likewise engaging in the hub opening (27). The ring shells (33, 35) transmit the torque of a drive shaft (7) to the travelling wheel (5) and form a slip clutch for reducing torque shocks in the drive line. The three-piece design of the housing (1) permits the compensation of axial bearing play upon assembly. The peripheral wall part (17) can be made of thicker plate than the side wall discs (13, 15) conveniently provided with a bent-over lateral edge (63) and provides for a robust housing construction which can be fastened all round. In its centre part, the travelling wheel (5) can be made of a different material from the wheel-flange areas, in particular a material with emergency-running properties. <IMAGE>

Abstract: Preforms (1) by means of which interruptions in conducting paths are bridged and electrically and mechanically connected to the conducting path on both sides of the interruption have hitherto been made by stamping from a solder-coated metal band. As the width of the conducting paths has become reduced to less than 100  mu m, such a stamping process is no longer possible due to the instability of the stamping die. The approach of the solution uses the etching technique for making a preformed panel (2) with a plurality of preforms (1) but attention must be paid to the fact that the solder layer (3) must not yet be applied to the metal band (5) at the time of the etching. This is done to circumvent so-called underetchings. The invention provides that a solder layer (3) is applied by means of sputtering to the etched-out preform (1) which only consists of the substrate (4) which was made from the metal band (5).

Title: Transverse flexible suction  device of elastic material for gripping the valve bottom of a valve bag, and use of such a device
Inventor: GRAEFENSTEIN THOMAS M DIPL-ING
IPC: B65B43/18
Filed: 1989-05-05
Abstract: This device comprises one or more suction chambers having suction bores situated in the flat chamber bottom which face the valve to be gripped. It is intended to provide a device of this type in which a reliable gripping of the bag bottom by means of the flat suction-chamber bottom or bottoms and a similarly reliable opening of the bag valve is ensured. In this arrangement, it should be possible for the extensibility of the bag valve, that is to say the distance between the two initially parallel valve walls, to be varied. For this purpose, the device is provided, in a parallel plane (E, K, N, R) which is remote from the plane (F, H, M, T) of the suction-chamber bottom (11, 24, 35, 51), with one or more pressure chambers (10, 26- 28, 38-41, 60) which act in this parallel plane, the device becoming curved transversely when pressure is applied to said chambers. <IMAGE>

Abstract: The invention concerns emptying devices, intended in particular for bag-in-box packagings, whose functionally essential elements can be moulded in one piece during manufacture of the connection piece or bung of the container, which is welded to the plastic bag of the bag-in-box packaging, the bung (5) can be easily closed because when the bag is filled, a closure body (6) in the form of a valve (12) is forced into the bung. To this end, the valve (12) has a cross-section (13) which varies in the direction of the longitudinal axis (23) of the bung on either side of the emptying spout (7), and a corresponding enlargement or constriction of the cross-section is rotatably mounted in a sealed manner on the bung. As a result, the emptying device is reduced in a very simple manner to particularly advantageous two-part systems, in which the tap is incorporated in the bung; this greatly facilitates handling during emptying, particularly in cheap refill systems. Technically precise fixation during the filling operations is also guaranteed.
