Title: Tool holder for tyre removing rig - has controlled spacing to prevent damage to alloy wheel rims
Inventor: PETROLATI LIVIANO
IPC: B60C25/132
Filed: 1980-04-26
Abstract: A tool holder for a tyre removing rig has the profiled tool (10) on the end of a pivot arm (8) and with vertical adjustment for the tool. The wheel is clamped to the bed of the rig and the tool inserted between the wheel rim and the tyre bead to lift the tyre off the rim. Once the bead is gripped the tool holder lifts the tool away from the rim edge. The tool is lifted by a foot control (4) operating a servo.

Title: Starting air feed for diesel engine - has air feed transfer valve between cylinders closed while starting feed valves are open
Inventor: DEUTSCHMANN HERBERT DIPL ING
IPC: F02N19/00
Filed: 1980-09-16
Abstract: The diesel engine has the cylinders divided into two sets. During starting a transfer valve (23) allows air compressed in one set of cylinders (14) to enter the other set (15) to supercharge this set and aid starting. The engine is turned over for starting by compressed air admitted to all cylinders by starting valves (32). The starting valves are operated by a control (30) which is connected to the crankshaft. The control has a further output (34) to the transfer valve (23). It closes the transfer valve when the starting valves (32) are open. This prevents the transfer air from acting against the starting air.

Title: Bonding end closure to hollow section for a gas-flow conduit - involves electromagnetic forming, reducing preparatory work and forming friction bonding joint
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/05
Filed: 1980-10-29
Abstract: The gas throughflow conduit is based on an elongated hollow section, generally extruded, without transverse partitions, bounded by end closures of similar or different materials/alloys embodying additional partitions for internal compartmentation. The two are joined by positive or material-bonding friction joints. The pressure necessary to reduce the dia. of the closure where it bears against the hollow section external surface is applied at least partially without mechanical contact, by electromagnetic forming. Slotting of closure rims or angling-in of butting edges - as appropriate - is thus eliminated.
