Title: Process for moving dividing plates of a pressure or injection moulding mould for roller bearing cages out of the pockets for rollers or needles, and also apparatus for performing this process
Inventor: LEGROM FRIEDRICH
IPC: B22D17/24
Filed: 1983-05-19
Abstract: In a process for moving out two dividing plates which, in a pressure or injection moulding mould for the production of a roller bearing cage, produce the pockets receiving the rollers or needles of this bearing, and which are provided with holding projections for the roller bodies, the first dividing plate is moved radially to the cage, entraining the second dividing plate at first in approximately the circumferential direction of the cage and thus coming free with an undercut from an existing holding projection, after which the first dividing plate moves the second dividing plate, likewise in a radial direction, with it out of the pocket. This kind of plate movement permits guiding both dividing plates, superposed over a large area and hence supporting each other, so that cage pockets of a small internal diameter can be produced. The first dividing plate has no undercut requiring a releasing motion.

Title: Mechanical transfer system for a catalytic converter or the like
Inventor: BROOKS WILLIAM ROBERT
IPC: B65B3/04
Filed: 1983-07-15
Abstract: The invention relates to a device for injecting a special admixture into a prefilled product container, with an internal pressure which is greater than one atmosphere. A connection element (40) is designed with a cavity to accommodate a container element (26) so that the latter is fixed tightly and is aligned. The said connection element (40) has a structure (60, 64) which can be used to position a spray assembly (42) in relation to a penetratable section (34) of the container element (26). A spray assembly (42) has a spraying element which is attached to the structure and contains an inside chamber (68) for receiving a metered quantity of a liquid admixture to the product or to accommodate upgrading of the product, the spray assembly in addition containing a hollow needle (70) which is attached to the spraying element and is joined to the product admixture chamber in such a way that liquid can be transferred. A rotary element (44) can be combined with the connection element (40) and has an actuating element which optionally engages with the spray assembly and reduces the internal volume of the product admixture chamber by the application of force. A force multiplying device (46) is arranged to work between the connection element (40) and the rotary element (44) so to exert a load on the actuating element in order to press the contents of the admixture chamber out through the needle and into the product container, against the internal pressure of the latter. <IMAGE>

Title: Piston and connecting rod arrangement
Inventor: SCHAAB KARL HEINZ
IPC: F02B75/32
Filed: 1983-07-22
Abstract: In a new piston and connecting rod arrangement, the connecting rod (14) is of multiple-element construction and comprises a shank (24) which transmits only compressive forces from the piston (12) to the crank pin (32), and a plurality of tension loops (26) which surround the gudgeon pin (16) and the bearing shell (30) of the crank pin (32) and transmit only tensile forces. At the bottom, the piston (12) has a trough-shaped bearing surface (A) and, opposite the connecting rod (14), a likewise trough-shaped bearing surface (C). During the transmission of compressive forces from the piston to the connecting rod, an essentially rectilinear power flow in the longitudinal direction of the connecting rod is possible via these bearing surfaces (A, C), allowing a lighter-weight construction. <IMAGE>

Title: Tape-indicating device for a magnetic tape cassette
Inventor: WOELFLICK FRANZ
IPC: G11B23/087
Filed: 1984-07-30
Abstract: Known devices for indicating the tape running and the tape supply in a magnetic tape cassette permit only an approximate estimation of the reproducing or recording time which has elapsed in each case, with the aid of a window on the upper side of the housing of the cassette bearing an approximate scale. With the tape-indicating device according to the invention, which comprises a double-armed spring (12), contacting one of the two reels, namely the tape winding-up reel (14) and the tape unwinding reel (15), and a scale indicating the forward running of the tape in minutes, an accurate indication of the reproducing or recording time or of the run-off tape length is attained. In addition, the spring (12), the freely movable end (12a) of which is visible as a pointer on the scale (11), has the effect of pressing the magnetic tape (18) against the reels, so that looping of the tape is prevented. <IMAGE>
