Title: Press for mfg. shaped sand bodies esp. for brake calliper core mould - includes shaping tool having upper- and lower parts working together with guiding mandrel to obtain burr-free core mould
IPC: B22C13/12
Filed: 1990-01-04
Granted: 1991-01-31
Abstract: Hydraulic press for mfr. of cores for casting tyre rims has a filling frame (2), central guide mandrel (3), upper (4), and lower (5) tool parts with abutting edges, forming a mould cavity. The edge on the lower and/or upper tool facing the mandrel is in the form of a wedge-shaped parting rim (7) with a clearance angle on the mandrel side. After the mould is filled with green sand, the upper tool is returned to its starting position and the lower tool is raised to a distance from the upper part and the mandrel is raised above the lower tool. The tool parts are then brought together into the mandrel-free area and the mandrel is returned into position. The upper tool is raised above the mandrel and the lower tool is raised into the upper edge region of the mandrel for ejection of the core. ADVANTAGE - Cores are mfd. without flash.

Patent DE-4110830-C1 (DE)
IPC: A24C5/42
Filed: 1991-04-04
Granted: 1992-05-27
Abstract: The invention concerns a device for filling prefabricated cigarette tubes, the device having a housing (1), a tobacco chamber (17), a trough-shaped tobacco holder (7), a compression bar (23), a stop (31) for one end of the plug of tobacco, a finger (14) on which one end of a cigarette tube can be placed and a sliding cover (11). The length of the plug of tobacco formed can be adjusted to fit different cigarette-tube tobacco-spaced lengths by altering the length of the tobacco chamber (17) and the length of the compression bar (23). The invention does this by virtue of the fact that the end stop (31) is adjustable in a direction parallel to the longitudinal axis of the tobacco holder (7) and that at least two sections (41, 42, 43) of the compression bar, each of different length and each capable of acting as an extension to a stationary part (30) of the bar, are mounted on a rotating component (40) whose axis of rotation (45) is parallel to the surface (44) of the compression bar.
Patent DE-4119209-C1 (DE)
IPC: E21B19/16
Filed: 1991-06-11
Granted: 1992-07-30
Abstract: The invention relates to a simple device for releasably connecting a drill pipe to a rotary drive, the production, maintenance and use of which involve little expense. The device avoids the dangerous handling at a height of 6 to 8 m in the area of the rotary drive and at the top end of the drill pipe. The device according to the invention has a transmission means with which the torque can be transmitted over a relatively large distance, for example from the ground, to the connecting element, for example a push-in pin, which is guided in an axially displaceable manner in a connecting means at the rotary drive. This means is designed, for example, as a crankshaft and advantageously has a telescopic section as well as an element which can perform an angular movement, for example a steel rope of predetermined flexibility or a universal joint. The releasable connection between the transmission means and the displaceable push-in pin is formed by a hook on the transmission means and a ring on the connecting means, the ring being connected via a pivot pin to the rotationally-fixed push-in pin. <IMAGE>
Patent DE-4300376-C1 (DE)
Title: Cushioned seat parts prodn., having different hardness - by adding foaming resin to covering in mould, curing, replacing top mould tool by one with undercut, and adding resin binder plus top covering
Inventor: STORCH HELMUT
IPC: B29C44/58
Filed: 1993-01-09
Granted: 1994-01-05
Abstract: A cushion for a seat with areas of different hardness is produced by laying a covering in a mould, closing the mould or its opening with a top tool, and adding a resin to the cavity beneath the top tool; this resin used is a reactive mixture which expands into a soft foam and fills the cavity to form part of the cushion. The top tool is next removed and replaced by another, the foam core remaining in place, leaving a second cavity between itself and the second top tool; this second cavity is however thinner than the first and corresponds to the hard part of the final cushion; a second resin is then added to this second cavity. The mould is designed to provide an undercut near its inlet; when it is closed by the first top tool the undercut is closed off from the first cavity by that tool; when the second top tool is applied the second cavity on top of the foamed core then includes the undercut for filling with the second resin. ADVANTAGE - In the procedure the edges of the covering used are removed cleanly from the product.
