Title: Automotive vehicle
Inventor: STIEFEL HERMANN
IPC: G05D1/02
Filed: 1982-04-20
Abstract: An automotive, driverless and trackless vehicle, for example a lifter truck or stacker (1), is steered in a known manner by means of a guiding wire (10) or the like laid in the floor and a swivelable sensing element (8) which is activated for forward travel. For rearward travel, a fixed, central, rear sensing element (14) or two rear sensing elements (12 and 13) which are mounted on the fork prongs or fork-shaped chassis components of the vehicle and are also fixed take the place of the swivelable sensing element (8). In addition to these sensing elements, a fixedly mounted sensing element (11) which also interacts with the guiding wire (10) is provided at the end of the vehicle which is at the front in the direction of forward travel. However, it is provided in particular that this fixedly mounted sensing element (11) is switched on at the start of a straight route with the aid of switching devices (15 and 16) set up along the route and operating preferably in a wireless fashion, and switched off again at the end. As soon as the vehicle comes to rest too far to the side of the guiding wire (10) on the left or on the right, this fixedly mounted sensing element (11) causes the vehicle to be stopped without delay so that despite rapid forward travel the vehicle is reliably prevented from leaving the foreseen route or from colliding with one or other shelf when travelling over narrow corridors between shelves. The fixedly mounted sensing element (11) monitors both straight-ahead forward travel and rearward travel. When going round bends it is, as stated, switched off irrespective of the travel direction. <IMAGE>

Title: Dough dividing and kneading machine with drum and oiler
Inventor: SCHROEDER REINHARD
IPC: A21C7/00
Filed: 1983-06-03
Abstract: The invention relates to a dough dividing and kneading machine, in which a drum (1) provided with measuring chambers (5) is drivable in a stepped manner and an oiler is arranged on the drum circumference between a filling device (8) and a kneading device (12) and the filling device has a shearing edge (7). In this connection, it is desirable for the oiling of the dough piece outer sides which form the kneading connection to be improved. This is achieved in that the drum (1) can be driven from standstill with a low circumferential speed during the movement of a measuring-chamber (5) row past the shearing edge (7) and the high circumferential speed can be set during the rotational stage. As the shearing-off process is slowed down, no irregularities or folds arise on the outer sides of the dough piece during the shearing off of the dough situated in the measuring chambers from the dough situated in the feeding chamber. <IMAGE>
