Patent DE-4328687-A1 (DE)
Title: Shredder operating by the rotary-shears principle
Inventor: KROHM REINHOLD
IPC: B02C18/24
Filed: 1993-08-26
Abstract: A shredder operating by the rotary-shears principle is equipped with two tearing shafts which rotate counter to one another and are each provided with separate drive units. It is thus possible to equip such a shredder, designed as a slow-speed unit, either with uniformly driven tearing shafts or else with tearing shafts which run at different rates, with the result that the drawing-in effect of the two tearing shafts can be increased or varied in a specific manner. Extremely different types of materials can thus be drawn in and comminuted in an effective manner, the arrangement of a screen or other devices also making effective classification possible, with the result that a very uniform end product can be achieved. The rotor cutters arranged on the tearing shafts may be provided with one or two teeth or else also with self-rotating straight-shank chisels, with the result that a very wide-ranging application area can be catered for by such shredders. <IMAGE>

Inventor: HAAS THOMAS DR
IPC: C07C209/48
Filed: 1993-12-22
Abstract: The invention is aimed at an improved process for the continuous preparation of 3-aminomethyl-3,5,5-trimethylcyclohexylamine in high yield and high purity (isophoronediamine) from 3-cyano-3,5,5-trimethylcyclohexanone (isophoronenitrile) by aminating hydrogenation with hydrogen and ammonia in the presence of a solid bed catalyst. Isophoronediamine is a raw material for the preparation of isophoronediisocyanate, an amine component for polyamides and a curing component for epoxy resins. According to the invention, the aminating hydrogenation is carried out by allowing a mixture of isophoronenitrile, ammonia and a C1-C3-alcohol to trickle over a trickle-bed reactor provided with a Co and/or Ru solid-bed catalyst at 3 to 8 MPa and a temperature of 40 to 150 DEG C, preferably 90 to 130 DEG C, in the presence of hydrogen and working up the reaction mixture by distillation. A high-boiling by-product fraction, containing a bicyclic amidine, is preferably added to the mixture to be hydrogenated, whereby the yield is appreciably increased.

Patent DE-4401873-A1 (DE)
Title: Appts for nitrogen-cooling food esp. meat in rotating vacuum drum
Inventor: HENNEKEN FERDINAND
IPC: A23L3/375
Filed: 1994-01-22
Abstract: An assembly treats food esp. meat with a coolant within a rotating vacuum drum (1) sealed on one side by a cap (10) through which a fluid coolant (K) esp. nitrogen is introduced. The coolant subsequently emerges through an outlet (30) drawn by a vacuum pump (33). The novelty is that the gas egress pipe (31) size and drum (1) shape are so chosen that the evaporating coolant generates over-pressure in the drum, such that emerging gas passes at very high speed through the drum (1) outlet (31) without use of an extruder fan. A gas effluent valve (AV) is located within the gas outlet pipe (31) which is opened and closed at chosen intervals by a control unit (ST). It either releases the gas to the outside (G), or links the gas outlet (31) to the vacuum pump (33) and prevents emissions to the outside.

Title: Method and appts. for running hot-rolled wide strip or similar product on a roller conveyor
Inventor: KRENN WALTER DIPL ING
IPC: C21D9/00
Filed: 1994-10-05
Abstract: The method is novel in that a) the stagnation shock caused by run-on or lift-up of the strip front (17) at rollers is substantially reduced or completely eliminated, b) the lay-on pattern of the (in particular, wavy) strip on rollers is improved by a top waviness limiting device, preferably by one which applies compressed air. As a result, the stagnation pressure arising from strip velocity reduction (from the rolling velocity) is reduced/eliminated. Also claimed is the device for performing the above where the gaps between conveyor rollers are spanned by cover plates at a level close to the level of roller tops. Water-cooled waviness limiting plates (24) - whose undersides are preferably provided with compressed air outlets - are located above the conveyor so that their height is adjustable.

Title: Precise cylinder tempering in injection moulding of thermoset plastic
Inventor: LIEHR ERICH DR
IPC: B29C45/78
Filed: 1994-09-27
Abstract: Injection moulding machine cylinders are tempered to work with crosslinking polymers.  In each circuit, the measured cylinder temperature is compared to a given value, varying flow in accordance. Temperature is measured over the cycle, between cylinder inner- and outer walls, centrally between outlets.  Tempering is split into initiation-, and steady state operation.  In the first cycle at time Z1 a fixed duration temperature impulse tinit is introduced. Approaching the desired value of mean cylinder temperature, a lesser impulse tann is used, until it is undershot, ending the delivery phase.  Temperature impulses of duration tann are used in steady state operation.  After the last Z1, tempering impulse te and further impulses are introduced as necessary, up to Z2, near cycle completion.  Total duration per cycle is limited to tmax.  Impulse length te, and total duration tmax, are evaluated from an algorithm.
