Title: Animal fodder preparation plant - using hammer mill load and output weight for control of silo outlets
IPC: B01F15/04
Filed: 1980-09-11
Abstract: A machine for the preparation of animal feeding stuff includes a weighing device which is fed by a hammer mill and cuts off the outlets from the fodder component bunkers when a set desired weight has been reached. The outlets are also controlled in their passage area, i.e. when the hammer mill motor load rises, the area is reduced and the share, left in the hammer mill intake pipe for air, is increased. When the motor load drops, the reverse action is taken. This saves constant attention to the weight and leaves the operator free for other work. The automatic operation facilitates the use of low-cost electric off-peak current.

Title: Light barrier connected to mains via rectifier - has relay voltage feed operated according to mains voltage level
Inventor: MEHLGARTEN UWE ING GRAD
IPC: G01V8/12
Filed: 1980-09-15
Abstract: An optical system, with a light source emitting pulses of light periodically, has a receiver connected without a transformer and via a rectifier circuit to the mains. It contains a relay which is actuated when light pulses are received. The transmitter and receiver can be connected to mains voltages of different amplitude and phase for a single path optical system. This is achieved with very low component costs. For the voltage feed to the relay rectified mains half-waves are passed for the duration of pulses from a generator controlled by the instantaneous mains half-wave value. The pulse generator is operated by a retriggerable monostable multivibrator connected to a photoelectric receiver. The multivibrator output signals are longer than the periods of the light pulses and mains voltage. The rated voltage of the relay is smaller than the average mains voltage.

Title: Frame-shaped precast concrete member, in particular for slope or bank stabilisation
Inventor: SCHENK HARRY
IPC: E01F8/02
Filed: 1981-03-11
Abstract: A frame-shaped precast concrete member for producing a space-lattice wall as a retaining wall, lining wall, noise-protection wall or the like and in particular for slope or bank stabilisation is proposed. The precast member consists of at least two transverse webs (3, 3'). The transverse webs (3, 3') are connected to one another in a frame-like manner by longitudinal beams (1, 2). The transverse webs (3, 3') consist of an essentially horizontal main body (4) or Z-web and at its ends Z-legs (5, 6) in each case extending essentially vertically in the opposite direction. Starting from known precast members of this type, precast members are to be created which are fixed and secured in the longitudinal direction, in particular in bank stabilisation, by concrete parapets held by means of cast-in-situ foundations. To this end, it is proposed according to the invention that the longitudinal beam (2), in the area of the Z-legs or sections (6) extending downwards, is not to be arranged at their ends but rather in the transition area between main section (4) and section (6) of the transverse webs (3, 3'), so that a top part (7'a) can engage in the area between the sections (6), and a precast member can in this way be secured against longitudinal displacement. <IMAGE>

Patent DE-3142898-A1 (DE)
Title: Percussion drilling rig
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B7/26
Filed: 1981-10-29
Abstract: A percussion drilling rig is described which, hanging on a winch rope, operates autonomously in the bore hole, in the course of which a piston operated by compressed air does the striking and a coarse-pitch turborotor acted upon axially by the exhaust air from the piston translates the drill bit. In a novel manner, the compressed air is directed to the percussion and rotary mechanism at 300 to 1500 bar from a liquid-air bottle which can be changed quickly and is designed for a drilling period of 1 to 10 hours, the bottle being relatively long and heavy. It is desirable for the bottle to be heavy for fitting it into the deep-drilling device, because the latter, operating autonomously in the hole without rods, utilises the bottle and drill-head weight as drilling pressure instead of the conventional drill stem. The percussion mechanism is arranged behind the turborotor so that the latter fills the nose of the drill head. The bottle forms the tail, and put over it as system end is a bush for the drillings which fills with drillings and conveys them to the surface when the unit is pulled out of the hole.
