Title: Prodn. of smooth bead area on tyres - where small plastic or rubber ring is inserted in mould to form smooth transition area between bead-forming part and bag press
Inventor: FRERICHS UDO DIPL ING
IPC: B29D30/06
Filed: 1990-07-31
Abstract: A tyre is produced in which the beads are on the radially inner circumference of the rim. When the raw tyre is being cured the bead and lower sidewall are moulded smooth by means of metal rings and the rest of the tyre is pressurised internally with a heated bag press. The transition area between the bead-forming ring and the bag is formed by a plastic or rubber ring. The figure shows the female mould segments (1,2) and blocks (3). To make the surfaces of the tyre smooth where they must be sealed against the rim the set-up has two bead-shaped rings (5) which can be moved radially. The rest of the structure is conventionally moulded by the heated bag method so that the raw tyre is pressed against the tools (2,3). Both the bead-shaping rings (5) are extended by plastic or rubber profile rings (7), each of which fits into its recess on the block ring (5) so as to present one flush face for application by the bag (10). The ring (7) is aligned obliquely so that the bag (10) meets its tip at the sidewall at an angle of less than 10 deg.. ADVANTAGE - The procedure eliminates the current problems of slight displacements in the transition area concerned (which arise from the differential pressure applicable and which cause internal material to stand out).

Title: Electronic frequency monitoring of linear and rotary movements - using two retriggerable monostable multivibrators for machine or plant
Inventor: WIEDERHOLD MICHAEL
IPC: G01P1/10
Filed: 1990-11-06
Abstract: The multivibrators (1.4), for the prodn. of different holding times, are operated by supply voltages (U1,U2,(9,8)) of different levels. The multivibrator (1) reached first by the square wave voltage is operated at a lower supply voltage (U1,9) than the second multivibrator (4). Both multivibrators (1,4) are wired with similar RC elements. The supply voltage for prodn,. of a hysteresis at the moment of the changeover of the charging current for the time determining capacitors (3,6), is lowered at increasing frequency and increased at reducing frequency. One of the multivibrators is logically connected to an AND-gate. The output of the multivibrator (4) as well as the output of the AND-gate (7) are connected to constant current sources (2,5) for attaining a lower current from the change-over point upon increasing frequency, or a higher current from the change-over point upon reducing frequency, and thus the formation of hysteresis. ADVANTAGE - Larger adjustment range for switching point.

Title: Auger-type slurry centrifuge - has auger turns of finer pitch inside tapering portion of cylindrical drum
Inventor: SCHILP REINHOLD DR
IPC: B04B1/20
Filed: 1990-12-27
Abstract: The auger-type centrifuge separates slurry etc. into a phase with low liquid content and enriched with solids to the maximum degree, and a phase containing the minimum amount of solids. It comprises a cylindrical centrifuge drum tapering at the discharge end and rotating on a horizontal axis, and containing a conveyor auger rotating at a different speed. The drive mechanism is electric and/or hydraulic. The pitch of the auger turns (3) is finer inside the tapering portion (1') of the drum (1) than inside the cylindrical one (1"). When a predetermined torque value is approached or exceeded for the auger, a controller (10) increases the difference between its speed and that of the drum. A speed-control (11,12) is adjustable to give a centrifugal pressure of at least 20 bar at the drum inside wall. ADVANTAGE - Maximum separation under heavy load where solids content fluctuates.

Title: Clutch control for servo drive - uses control current in servo solenoid to monitor differential speed inside clutch
Inventor: AHNER PETER DIPL ING
IPC: B62D5/04
Filed: 1990-12-29
Abstract: The servo motor provides additional torque to a drive, e.g. servo assisted steering. To measure the amount of clutch slip, i.e. the difference in speed between the clutch sections, the servo solenoid is provided with a programmed current. This provides a magnetic current across the clutch and this current is monitored to determine the amt. of clutch slip. One part of the clutch has a segmented structure to enable a simple digital measurement to be obtd. for the clutch slip. A simple processor control regulates the application of the solenoid to minimise torque shocks. ADVANTAGE - Simple servo clutch control; no separate sensors required.

All of the hydraulic cylinders are of the same size and type, and move in such a way that the length of the belt is not varied. USE/ADVANTAGE - In composting systems for converting organic waste, agriculture, cattle husbandry, parks and gardens. Provides efficient use of the available composting system capacity and allows fractionated composting to be carried out. The sizes of the device and of the system are flexible, so that the capacity of the system can be increased or reduced at little cost, while at the same time allowing access to all phases of the composting process. The time periods required for the process are also reduced.
