Title: Feeder insert in casting mould - defines surrounding cavity which becomes filled with melt during pouring
Inventor: BAUR EDUARD DR ING
IPC: B22C9/08
Filed: 1973-02-23
Abstract: The insert may be made of solid-resin-asbestos or of asbestos board. Around its outside, and its top, if it is closed at the top, is a layer of destructible matl. e.g. foamed plastics or corrugated cardboard. Apertures lead from the insert inside through the walls to supply melt outwardly, and during pouring the layer is destroyed by the melt contacting it.

Title: Arrgt. for grinding rear face of hollow cylindrical workpiece - workpiece is hydrodynamically supported on spindle
Inventor: THIELENHAUS ERNST
IPC: B24B41/06
Filed: 1974-02-15
Abstract: The rotating workpiece carrier consists of a stepped spindle with chamfered end and a self aligning spherical bearing mounted on the step. A clamping plate and a elastomer ring are mounted on the end of the spindle. The hollow cylindrical workpiece is placed over the spindle until its end face engages with the self aligning bearing. When the workpiece is in position, the clamp plate is operated and the elastomer ring is forced against the inside of the workpiece and secures it in position. The cylindrical workpiece is surrounded by a sleeve, with a clearance between the workpiece and the sleeve, and this space is connected to a source of pressurised hydraulic fluid which gives hydrodynamic support to the workpiece. The end face of the work piece is ground by a cup shaped grinding wheel.

Title: Cigarette lighter with HV ignition spark - has cover system for protecting burner when the burner is alight
Inventor: DIETERLE HORST
IPC: F23Q2/28
Filed: 1974-02-21
Abstract: The burner is housed within a chamber which has a flame opening at the top and it has also side walls with air inlet openings. The lighter is operated by a pressure lever.

Title: Fruit juice extraction system - retaining pulp in reactor with perforated partition before filter press
Inventor: ANDRES ERNST-ULRICH
IPC: A23L2/04
Filed: 1974-03-27
Abstract: Fruit juice is prepd. from apples, stone fruit or berries by crushing them to a pulp which is kept in a reactor with a perforated partition for 20 to 40 minutes and heated. The pulp is then passed to a press with endless filter cloth strips; the resulting juice is directed to the same storage tank as the juice from the reactor. The prior juice extn. in the reactor results in a simplification and greater efficiency of the final press operation. Yield and output of this process are excellent.
