Title: Driving mechanism for industrial mechanical vibrator - uses rubber rollers to transmit drive between out-of-balance shafts
IPC: B06B1/16
Filed: 1975-03-07
Abstract: Vibrators used for driving mechanical sieves employ a pair of parallel shafts (48, 50) mounted in bearings (40, 42, 52, 54). The shafts carry eccentric masses (62, 64) and are arranged to rotate at equal speeds but in opposite directions. The line of the resultant centrifugal force is arranged to pass through the centre of gravity of the sieve but as the material moves, the centre of gravity also moves. With a toothed gear drive this shift of the centre of gravity causes tooth wear. The invention proposes using rubber rollers (76) which allow a degree of slip so that the line of action of the force is automatically adjusted to pass through the centre of gravity.

Title: Process and apparatus for drying active yeast
Inventor: KUELLING WALTER
IPC: C12N1/00
Filed: 1981-10-09
Abstract: The moist yeast (M) which has been comminuted and disaggregated in an extruder (2) is adjusted in a predrier (9) and a secondary drier (16), both of which operate on the fluidized bed principle, to a dry matter content of about 90%. In order to be able to carry out the subsequent drying economically, the product from the secondary drier (16) is placed in a silo (26), which is situated in a closed circulation charged with nitrogen. Moisture is continuously removed from this circulating nitrogen by an absorption drier (30). In order to save energy, the air leaving the secondary drier (16) is fed via a line (36) to the predrier. The heat contained in the air leaving the predrier (9) is used in a heat exchanger (42) to preheat the air entering the secondary drier (16). The results in the production of instant active yeast are a demonstrably greater overall efficiency, a higher dry matter content and less environmental pollution. <IMAGE>
Patent CH-666840-A5 (CH)
Title: Metal or metallic oxide tape, strip, or foil
Inventor: HEINEMANN WILFRIED DR
IPC: B22D11/00
Filed: 1982-11-12
Abstract: Metal or metallic oxide tape, strip, or foil produced to any desired width by ejection of molten material through a nozzle or a series of nozzles on to a cooling drum revolving at controlled speed. The nozzles can be located adjacent to each other or in staggered or echelon formation to suit specific requirements. The molten metal is ejected through narrow slits in the nozzles to coalesce on the revolving cooling drum at the required width where it is solidified by the cooling effect of the drum surface. The tape, strip, or foil is released from the drum by gas or air. The nozzles can be fed from a single supply source or independently. This permits separate melting and ejection of materials of differing structures e.g. amorphous or crystalline, to flow on to the cooling drum, coalescing and fusing to form the required total width yet retaining their sharply defined individual structural properties in parallel. Alloying combinations can also be produced in the same way. Alternative profiles in the strip or foil can be obtd. by grooving or segmentation of the cooling surface. Tape, strip or foil can be produced economically to desired width. By utilising a series of nozzles and individual feeding strip or foil can be produced to desired profile  containing varying structural and alloying characteristics in parallel.
