Title: Flexible rack rod shearer haulage - uses flat link side teeth to complete rack and pinion, flat links joined by round links and pan-mounted holders
Inventor: GARTE RUDOLF
IPC: E21C29/10
Filed: 1976-01-08
Abstract: Flexible rack rod for coal shearer haulages is designed as roller link chain. The shearer drive force is passed to the rod using the flat designed links and associated flanking teeth similar to a rack and pinion system. The flat links are connected by up-ended round links. The flexible rod system is accommodated in the pans using the holder and adjusts lengthways within limits to compensate for pan movement in both planes. The round link should have relatively smaller pitch, as compared with that of the flat link which can thus take up the play resulting from pan shifting. Guide pins fitted to the flat links should prevent loss of alignment lengthways or transversely.

Title: Linear motion drive from rotary motor - has drums of different dia. to produce high load without reduction gear
Inventor: FICKLER HANS
IPC: H02K7/06
Filed: 1976-10-19
Abstract: An electric motor (1) has an extended shaft supported in an outrigger bearing (2). The shaft carries two drums (13, 14) of different dias. A cable (4) is would around the drum (14) and then passes around the pulley (7) attached to the rod (8). The cable is then brought back and wound round the drum (13) in the opposite direction to the winding on the drum (14). When the motor (1) rotates the cable is paid out from one drum and hauled in on the other. This differential motion results in a high load being exerted on the rod (8). This system of differential drums avoids the use of expensive reduction gears for linear motion drives requiring a high force.
