Title: Resilient type arms on printer - are displaced by hammer mechanism with movable abutment for varying hammer momentum
Inventor: BRESSLEIN HELMUT ING GRAD
IPC: B41J9/26
Filed: 1976-04-06
Abstract: A printing machine has a rotary head (1) having resilient radial type arms (2) bearing different characters. Printing is effected by a single hammer (21) programmed to hit any one arm which is halted at the printing station. The momentum of the hammer is varied in accordance with the requirements of the different characters. There is a resilient abutment (36) which is movable into or out of the way of a lug provided on the hammer, the movement of the abutment being in accordance with the position of a cam secured to the rotor. The cam acts on a mechanism (30, 33) which moves the abutment.

Title: Yacht self steering gear - has wind-vane operated double acting valve controlling pressure in tiller actuator with Bowden cable feedback of rudder movement
Inventor: SCHWING FRIEDRICH DIPL ING
IPC: B63H25/04
Filed: 1976-11-13
Abstract: The yacht self steering gear comprises a windvane (20) on a pivot (19) set parallel to the axis of jaw.

Title: Encased fuel injected engine for tractor - has fuel from tank cooled before entering injection pump dependent on temp. within casing
Inventor: THANNER JOSEF
IPC: F02B77/13
Filed: 1977-02-02
Abstract: The system maintains constant the full load output of the fuel-injection engine, encased in a noise-attenuating housing, of an industrial or farm tractor.

Title: Transverse cutting machine for continuous strip materials - has auxiliary drive to lock machine at TDC if fault occurs
Inventor: SCHNEIDER FRANZ ING GRAD
IPC: B26D7/24
Filed: 1977-08-05
Abstract: A machine which cuts continuous strips of material transversely is driven by a main motor connected by the transmission system to the auxiliary motor. On machine failure, a signal is transmitted to the control circuit which cuts off the power to the auxiliary motor. When the cutting blade of the machine reaches top dead centre the transducer transmits a signal to the control system which, in turn, transmits a signal through the circuit which applies the electro-magnetic brake and stops the motor. This results in the cutting blade of the machine being locked at its t.d.c. position.
