Patent DE-3826461-C1 (DE)
Title: Method and device for the centrifugal sterilisation of milk
IPC: B04B1/10
Filed: 1988-08-04
Granted: 1990-02-15
Abstract: Germ-infested milk is fed via the inlet 12 to the centrifugal drum 1 and then enters the plate insert 4. The germs separated here are collected in the concentrate chamber (5). Concentrate which contains a relatively small number of germs is constantly discharged from the concentrate chamber 5 via the discharging channels 6 and the nozzles 7. It reaches the stripping chamber 8, from which it is conveyed back into the inlet 12 via the concentrate outlet 10 and the return pipe 11, by means of the stripping element 9. The residual concentrate which contains a relatively large number of germs is discharged by means of periodical opening of the discharging apertures 14. A substream is made to branch off from the return pipe 11 and combined with the concentrate discharged from the discharging apertures 14. The volume of the substream is regulated in such a way that a stream of concentrate of constant output is achieved after combination has taken place. <IMAGE>
Patent DE-3923398-C1 (DE)
IPC: G01P3/489
Filed: 1989-07-14
Granted: 1991-01-03
Abstract: Rotation detector having a rotor (R1) with different attenuation regions (RBA, RBB) about which sensors (1, 2, 3, 4) are arranged which contain an oscillating circuit whose oscillating frequencies are counted in each case after a short excitation, and from this a comparison with a discriminator threshold is used to determine from the undershoot or overshoot of said threshold the respectively obtaining attenuation, and thus the rotor position, and metering signals are transmitted accordingly to a counter. The discriminator threshold is obtained in each case by summing the numbers of oscillations of sensors (1, 3; 2, 4) which are arranged in a complementary fashion with respect to the attenuation regions (RBA, RBB). A monitoring circuit for the oscillating circuits is provided, as are a redundant sensor arrangement and signal evaluation. The rotation detector is particularly suitable for battery-operated supply meters. <IMAGE>

Title: Sepn. and classification of solids - involves centrifuge with slide control system
IPC: B04B1/18
Filed: 1990-08-25
Granted: 1991-09-19
Abstract: Self-emptying drum centrifuge slide control is by fill/empty chamber to give axial slide movement and thus open and close the solids openings at the periphery.

A second control fluid line (14) should be provided with a third seal (15) and is also allocated to the ring channel (27). Pref. the second line has a variable choke (16) and both lines (14,9) are fitted with nonreturn valves (13,17). USE/ADVANTAGE - Separation, solids classification etc. Seal fitted control fluid lines permit low metering rate regardless of control fluid volume.
Patent DE-4191708-C1 (DE)
Title: Solid-state neodymium laser with tandem resonant coupling
Inventor: OPOWER HANS DR
IPC: H01S3/04
Filed: 1991-07-17
Granted: 1996-10-31
Abstract: A solid-state neodymium rod-laser comprises a pair of rods (46,48) mounted in grooves along the opposite edges of a water-cooled heat sink (78). Each rod is illuminated from a pump-light source (70,72) focussed by polished facets in the groove sides. Leasing occurs by resonant coupling between the rods via the opposing surfaces of two cylindrical mirror (38,40) and reflection from a mirror (32,34) placed at each rod-end. The output energy is transmitted through one (light-splitting) end-mirror as a parallel square section beam (54). The heat-sink can assume a cylindrical form with many similar pairs of watercooled rod-channels. The resonator mirrors become spherical and separate pumplight source is assigned to each rod.

Title: Drink-tap supplied under pressure - has drillings from valve-tappet recess for operating lever aligned with vent passages with tap shut
Inventor: BECKER CARL MEINHARD
IPC: B67D1/14
Filed: 1992-03-09
Granted: 1993-09-09
Abstract: The tap is for beer in particular, having a body detachable from a mounting surface and to whose head the drink is supplied under pressure. A valve sealing off the head from the spout has a cylindrical tappet(17) with recess(27) for the end of the operating lever. First and second vent passages connect the outside of the body and the inside of the spout to the tappet chamber. The tappet contains drillings(25a,25b) from the recess(27) to its external surface, and which are at the same distance apart as the mouths of the vent passages, with which they are aligned only when the tap is shut. On the edge of the part of the nozzle extending inside the spout there can be an oblique guide surface(26) extending in the liquid flow direction, and the tappet itself can be of plastic. ADVANTAGE - Ensures proper ventilation of spout with tap shut, while preventing additional air from penetrating into the spout when open.

Title: Four-finger stack-stretch-wrapping machine - moves fingers in pairs horizontally and successively inwards and outwards and for different distances
Inventor: BIRKENFELD RICHARD
IPC: B65B9/13
Filed: 1992-10-21
Granted: 1994-01-13
Abstract: Stretching sheet-material in hose form is extracted from a storage unit, parted off at the appropriate height and formed into a cowl. Four fingers sliding vertically and horizontally are inserted in the cowl, which is then folded into a bellows round them and stretched horizontally and pulled over the stack, keeping it clear of the latter's top edges, it being also stretched in the vertical direction before release. Before engagement with the cowl (17), two diagonally-opposite first fingers (13') are moved horizontally inwards for a first distance, after which the two others (13'') are similarly moved, but for a shorter second distance. After engagement with the cowl, the second fingers are moved horizontally outwards, followed by the first fingers. Inwards movement can be at a higher speed than outwards movement. ADVANTAGE - Simplicity, and requires little modification for use with cowls of different and particularly very small initial cross-sections.

Patent DE-4324264-C1 (DE)
Title: Draw key transmission for engines and drive units
Inventor: BARTOS STANISLAV FRANZ
IPC: F16D21/04
Filed: 1993-07-20
Granted: 1995-03-16
Abstract: The draw key (diving-key) transmission for engines or drive units, with gearwheels in permanent mesh, belongs to the category of mechanical transmissions with synchronisation. Conventional transmissions used in motor vehicles employ a fork shift. Here, the process of gear selection involves a change in direction of motion. By virtue of the fact that this draw key transmission involves a simple backward and forward motion of the gear lever, gear changing is considerably simpler and the draw key transmission is suitable for automation. At the same time, the advantages of mechanical transmissions are retained. This draw key transmission operates with the hollow main shaft (1) and selector rod (2), which can be displaced in the hollow main shaft, and individual gears are selected by means of its small keys (4). Power transmission takes place via these small keys and a flange (3) on the hollow main shaft. Synchroniser rings (8), both with the ability to move freely on the hollow main shaft, are arranged between gearwheels (7). Balls or detent pins in small keys actuate the synchroniser rings and lock the gearwheels once a gear has been selected. Intermediate rings (6) determine the path of the gearwheels or can be integrated into the gearwheels. Axial springs (9) between the gearwheels and the synchroniser rings determine the path of the synchroniser rings and allow synchronisation during selection. <IMAGE>
