Title: Sieve grinder plant for wet material - has grinding mechanism surrounded by rotating sieve basket into which blower is directed
Inventor: UNGER GUENTHER
IPC: B02C17/00
Filed: 1990-12-06
Abstract: The plant has two counterwise rotating grinding rollers (5) around which is arranged a sieve basket (4) supported by rollers (6). Through the portal opening extends a feed belt (3) on top of which is a funnel (1) and a vibro-feeder (2). The material fed into the sieve basket is picked up by lift blades arranged in the inside of the basket, and moved upwards until it falls between the grinding rollers (5). The rollers draw the material into the gap between them where it is ground, and the thus ground material falls downwards on to the basket sieve surface (4). The sieve surface (8) sorts out large pieces which are then transported upwards by the circulating sieve drier until it drops with other material between the grinding rollers. The small pieces of material drop into a collection tub (10) from which it is moved to a removal belt conveyor (12) by ejectors (9) on the sieve basket exterior. USE/ADVANTAGE - To reduce wet material which is difficult to grind.

Title: Doppler velocimetry method using light wavelength-independent length scales - generating surfaces of equal phase difference using interference of partial beams superimposed on measurement object
Inventor: HOCK FROMUND PROF DR ING
IPC: G01P3/36
Filed: 1991-09-02
Abstract: The Doppler velocimetry method using photoelectric measurement of motion components involves generating surfaces of equal phase difference as a measure of the displacement-time function of light-scattering objects. At least two pairs of partial beams produce phase-interlinked measurement signals through interference when superimposed in the measurement object. The signals are electronically or optically separated and the angle between the partial beams is arranged to give equal distances of the surfaces of equal phase difference for all pairs associated with a measurement component. The illumination apertures of the beams fed to the divider are limited to prevent overlap. USE/ADVANTAGE - E.g. for measuring fluid flow rates. Enables realisation of commercial, compact, 3-dimensional velocimeter system with signed movement component measurement.

Title: Process for lapping bevel gears - involves using controlled braking and acceleration of gears to produce even mating surfaces
Inventor: KATO SHOGO
IPC: B23F19/02
Filed: 1992-04-06
Abstract: This fixture and process is used in the lapping of bevel gears to produce a matching set. A disadvantage with existing processes is that if one gear has a defect i.e. non concentricity, this will become exaggerated. In this process one gear is driven and the other braked. The braking effect is so controlled that when the angular acceleration between the gears is at maximum the braking force is at minimum. This applies also in the reverse. This evens out the lapping action caused by abrasive powder producing uniform mating surfaces.

Patent DE-4214527-A1 (DE)
Inventor: THOME ROLAND DR
IPC: B29B17/02
Filed: 1992-05-07
Abstract: The invention relates to a process for recycling packaging materials containing one or more synthetic polymers and/or metal and/or natural polymers, with dissolution of the synthetic polymer component in a solvent and recovery of soluble and insoluble packaging constituents.   The object of the present invention is to develop an inexpensive and environmentally friendly process for recycling packaging materials containing one or more synthetic polymers and/or metals and/or natural polymers, in particular packaging composites. The disadvantages of the known processes are to be substantially avoided. In particular, the synthetic polymer component should be separated off in a manner suitable for recycling. The other components in packaging composites, such as the natural polymers present in cardboard (board) and paper, in particular cellulose, and metal, in particular aluminium, are likewise to be obtained entirely as individual components suitable for material recycling. This object is achieved according to the invention by a process in which the packaging materials to be recycled are treated with a solvent comprising aliphatic, naphthenic or aromatic hydrocarbons, hydrogenated products thereof or a mixture thereof. The solvent treatment is carried out until the synthetic polymer component has dissolved. The treatment temperature is between 0 and 500 DEG C. The solvents employed are, particularly, boiling fractions from primary and secondary petroleum refining whose boiling limits are in the range between 40 and 500 DEG C. The result of the treatment process is a liquid mixture of hydrocarbons of various structure and molecular weight in which the insoluble packaging constituents are dispersed. These insoluble packaging constituents, such as cellulose residues and aluminium, are separated from the liquid phase. The separation of the insoluble packaging constituents is followed according to the invention by the separation of the dissolved polymer component from the liquid mixture.

Title: Intruder alarm control covering several alarm points - classifies detected alarm signals into different groups assigned respective false alarm frequencies to prevent unnecessary call-outs
Inventor: REIMLER FRED DIPL ING
IPC: G08B25/00
Filed: 1992-09-18
Abstract: The control device is coupled to a number of intruder detectors (2-6) for registering the supplied alarm signals and indicating which detector or detector group has supplied the alarm signal, transferred to an external emergency call station (15). An alarm signal classification stage is inserted between the detectors and the transmission stage, classifying each alarm signal into at least two groups according to defined criteria. Each of these groups has a different false alarm frequency to supply the emergency call station with a primary alarm signal when the alarm signal is in a group with a low false alarm frequency and a tertiary alarm signal when the alarm signal is in a group with a high false alarm frequency. ADVANTAGE - Increased alarm reliability, i.e. reduced generation of false alarms so that response is more likely when real alarm is released.
