Patent DE-4326836-A1 (DE)
Inventor: MUELLER ROMAN
IPC: B02B3/06
Filed: 1993-08-10
Abstract: The method involves creating a sealed packing of the grain in the scrubbing chamber (111). Bearing strips on the scrubbing rotor (105) are formed of alternate fields of cams (112) and spiral conveyors (113) so that the cams mainly move the individual grains and the conveyors create an axial movement. The movement of the grains is improved by cams on the scrubbing chamber working with those on the rotor. The scrubbing intensity is changed by altering the gap between the bearing strips and the rotor and/or by positioning or regulating the backlog forces at the outlet (102). The grain is scrubbed in respective dry and wet stages.

Title: Rapid mill
Inventor: KLINKERFUS GUENTHER
IPC: B02C13/288
Filed: 1993-08-12
Abstract: The invention relates to a rapid mill for comminuting solid and liquid substances. The aim of the invention is to conduct various materials and/or liquids into the grinding zone avoiding sticking together, to homogenise them and to regulate the air speed. The aim is achieved by at least one inlet for material and/or liquid and at least one opening for regulating the air supply being arranged in the side part and opening into the radial slot of the rotor. The rotor is provided in the peripheral part with blades, as a result of which the first grinding stage occurs in the slot between the corrugated grinding path and the blades of the rotor, which at the same time is also the axial slot of the rotor. With the arrangement according to the invention, the grinding fineness can be regulated and also solid and liquid substances can be homogenised. <IMAGE>

Patent DE-4421710-A1 (DE)
Title: Swash-plate compressor and method for manufacturing it
Inventor: NAGATA HIROMI
IPC: F04B27/10
Filed: 1994-06-21
Abstract: The invention relates to a swash-plate compressor. The aim is to reduce abrasion or wear in a pressure-absorbing region of the cylinder block even in that case where outer rings of a bearing co-rotate with adjoining parts and in so doing carry out a superimposed eccentric movement, and to achieve this without increasing manufacturing costs. According to the invention, [lacuna] are manufactured from an aluminium alloy which comprises: from 1.5 to 3.5 % by weight of Cu, from 13 to 16 % by weight of Si, 0.5% by weight or less of Mg, 1.0% by weight or less of Zn, 1.0% by weight or less of Fe, the remainder being Al. With the exception of the primary Si crystals, the matrix is relatively soft. The primary Si crystals which protrude, independently of one another, beyond the pressure-absorbing regions tend to be forced into the base material by the outer rings of the thrust bearings (thrust blocks) so that the level or the height of the primary Si crystals can readily be approximately equalised. Consequently, the action and the pressure loading caused by the outer rings can be suitably absorbed by a large number of primary Si crystals, and a co-rotatory motion with a superimposed eccentric motion can be suitably accommodated, even when the operation takes place under high load, by a large number of primary Si crystals.
Patent DE-4426255-A1 (DE)
Inventor: BIEDERMANN ROLF DIPL ING
IPC: H04B7/005
Filed: 1994-07-25
Abstract: In order to reduce the power consumed by mobile radio transmitting/receiving devices (PT1, PT2) and thus increase their maximum possible duration of operation, the device-specific transmitting power is automatically regulated depending on special information (FSW, A-CRC, X-CRC), such as field intensity values (FSW) and transmission error values (A-CRC, X-CRC), received and acquired by the mobile radio transmitting/receiving device. The mobile radio transmitting/receiving device (PT1, PT2) has for that purpose a sequential control circuit (RK), in which the value of the controlled variables (here the device-specific transmitting power) follows the changing value of the command variable (here the received and acquired special information).
