Title: Power saw for cutting frozen foods - has electrically heated cutting elements connected to frame and handle
Inventor: LEPPER WILHELM DR-ING
IPC: B26B7/00
Filed: 1973-08-31
Abstract: This cutter is used for cutting of deep frozen food. The cutting elements such as knife blade or wire is held in a bracket and this blade or wire is heated with relatively high electric current. Behind the wire or a thin blade can be arranged a more solid cutting edge to ensure that the separated faces cannot be recontacted and refrozen to a solid piece. The blade holding frame has handles with the switch for connecting and disconnecting the current used for heating. The current is supplied from a transformer through a cable into the handle and through a switch. The blade can be heated directly or indirectly. The indirect heating is carried out by a heating element fitted within the cutting blade. The heated blade cuts material without producing debris and the manual effort used is small.

Title: Connector head for container filling system - has outer and inner pipe sleeves in connector driven down by descending container
Inventor: BRILL KARL HEINZ
IPC: B08B9/08
Filed: 1973-11-02
Abstract: Containers are set down on a fixed support and lowered into contact with two coaxial pipes in the connector fitted with in and outlines to link up with the fittings on the container, which are subsequently opened with increasing pressure to admit fluid in via two paths. The sprung sleeves forming the inner and outer pipes in the connector are forced progressively down against a spring until the container rim rests on a fixed support. An upper pressure ring on the outer pipe or sleeve stands proud of the inner sleeve in the top position by a pre-set amount. Drivers for the inner pipe sleeve, between this and the outer sleeve, have axial clearance greater than this pre-set amount and maximally the sum of this amount, the deformation of the seals and the opening stroke of the valve forming part of the container fittings. The spring loading the inner sleeve, exceeds the closing force applied to the fittings valve.
