Title: Appts. for casting porcelain hollow products - having two rotating transport devices connected via a transferring unit
IPC: C04B33/24
Filed: 1992-12-14
Abstract: Apparatus for casting hollow porcelain products in which the two rotating transporter devices (12,14) have rotating tables (16,62) spaced apart. The casting station (26) is rotatable about a vertical axis (20) which is also the rotating axis of the table (16). Gripping units (32,40) are located between the tables and rotate about axis (36) and move vertically along the same axis. The drying device (56) is only located around the second transport table (62). The second table has two levels (64,66). The first is for skin hardened drying of the moulding and the second level is for drying the empty mould after the porcelain has been removed. The empty, dry mould is then replaced in the lower table in order to allow its transfer back to the first table and further casting. The drying device (56) forms a channel around the second table except at the transfer unit between the tables. ADVANTAGE - The apparatus takes up only a small area and does not reduce the productivity.

Patent DE-4308637-A1 (DE)
Inventor: KRAXNER DIETER DIPL ING
IPC: F16H59/04
Filed: 1993-03-18
Abstract: The gear-changing device for a manual gearbox has a single gear-change slot for the gear lever of the gearbox, in which slot forward gears of the gearbox can be selected stepwise by pivoting the gear lever backwards or forwards manually out of a central position. For this purpose, the pivoting motion of the gear lever is converted into a translational motion of an intermediate member which displaces gear-change plates with gear-change gates in a gate change mechanism relative to one another. These gear-change gates are penetrated by a sliding block which is guided in a constrained manner by them and which is displaced from a first into a second end position upon each pivoting movement of the gear lever in the gear-change slot. The sliding block is connected by way of a cable control to the gearbox, in which individual forward gears are selected depending on the end position. <IMAGE>

Title: Method for the production of a predetermined breaking point on a machine needle
Inventor: GARTZEN JOHANNES PROF DR RER N
IPC: B23K26/40
Filed: 1993-06-24
Abstract: The invention relates to a method for the production of a predetermined breaking point on a machine needle with a needle eye, a thread guide groove and a stem. It should be possible to produce a reduction in cross-section of such a shape and in such a position that, given appropriate loading, the needle breaks at the desired point and exhibits a preferred direction of breakage. This is achieved by virtue of the fact that, to produce the reduction in cross-section, at least one straight transverse groove of suitable cross-section and/or at least one transverse hole of suitable diameter is introduced by means of a laser.
