Inventor: FOERSTER GUENTER
IPC: B65B51/00
Filed: 1988-10-07
Abstract: A gripping device has a plurality of grippers 1 which revolve about a shaft 6 and open and close to twist together wrappers of confectionery. The jaws 6 of the grippers 1 are operated by means of thrust bars 3 axially movable inside tubes 2. A bushing 10 is mounted inside each tube and is supported by a thrust bearing 11 subjected to the action of cam rollers 13 rolling along cam tracks defined by cam 14A, 14B, 17.

Title: Device for measuring the displacement of a displacer and method for operating such a device in a fuel injection system for internal combustion engines
Inventor: SIMONIS RAINER DIPL PHYS DR
IPC: F02M69/50
Filed: 1988-12-24
Abstract: In a device for measuring the displacement of a displacer which can move freely inside a measuring tube, in particular for application in a fuel injection system for internal combustion engines, a quick, exact and noise-immune measurement of the path length of the displacer is achieved owing to the fact that the displacer has a reflection surface for vibration signals whose direction of motion is directional, in that, further, a vibration signal transmitter directed onto the reflection surface is arranged at an end face of the measuring tube, and in that, finally, together with an electronic evaluation unit the vibration signal transmitter forms an interferometer for measuring the path length between the vibration signal transmitter and the reflection surface of the displacer.

Title: Mount that provides isolation of structure-borne noise, particularly for an internal combustion engine
Inventor: WEBER OTTO DIPL ING
IPC: F16F3/087
Filed: 1989-02-07
Abstract: In a mount providing isolation of structure-borne noise, which contains at least one spring block (3) made of elastomeric material between dish-shaped holders (1, 2), there is a clearance (a, b) between the sidewalls (1'', 2'') of the holders (1, 2), on the one hand, and the circumferential surface (3'), on the other, when the mount is free from dynamic loading. Given corresponding deformation of the spring block (3), this clearance disappears and a stop is thereby formed to provide an elastic limitation to the spring travel (Figure 1). <IMAGE>

Title: Apparatus and method for charging a shaft furnace installation
Inventor: SCHUERMANN PETER
IPC: F27B1/20
Filed: 1989-03-01
Abstract: The new apparatus for charging a shaft furnace installation with materials of different grain size fractions comprises silos (1) for said charging materials, at least one movable conveyor belt (3) and a rotary tub (4) installed above the furnace shaft, comprising circular compartments and having emptying flaps in the bottom.

Patent DE-3914497-A1 (DE)
Inventor: FAERBER JUERGEN
IPC: B65D77/28
Filed: 1989-05-02
Abstract: The invention relates to a package for liquid made of a coated cardboard composite, having a pierceable opening for a drinking straw, which has incisions 11 running towards one another in the form of rays or a star, and perferably a cutout 9 located at the star point of the incisions.
