Patent DE-3308417-A1 (DE)
Title: Roller mill
Inventor: FULLALOVE RICHARD
IPC: B02C4/32
Filed: 1983-03-09
Abstract: The roller mill has two grinding rollers (12,15), which form a roller gap to which material to be ground is fed by feed rollers (30). The grinding roller (15) is mounted on a balance (14) which is rotatably mounted on a pivot point (13) relative to an intermediate frame (11), so that when no material to be ground is present, the rollers can be moved apart by means of a cylinder (17) connected to the balance (14). The pivot point (13) is situated immediately above the common plane of the two rotation axes of the rollers (12,15), so that when the movable roller (15) approaches the fixed roller (12), it converges at an acute angle to a tangent to the fixed roller (12) in the roller gap, resulting in a considerable mechanical saving with only small force exerted via the cylinder (17). This tangential approximation is hence advantageous, in comparison with the radial approach of the movable roller in existing systems. <IMAGE>

Title: Manually operable mast foot positioning system for sailboards
Inventor: SCHEIDT WALTER R DIPL ING
IPC: B63B35/79
Filed: 1983-03-22
Abstract: The invention relates to a rail system with a slide for receiving a mast foot for sailboards. The rail system allows the slide in the rail to be released by hand by a pulling movement directed mainly upwards and to the rear on the mast and/or boom, and to be brought from one position into another without having to actuate a mechanism, for example using a foot. The system is constructed in such a way that the further forward the position of the slide is, the further towards the rear is the inclination of the vertical pivot axis so that forward propelling forces are conducted without excessive bending load on the joint. By preferably screwing the rail case to a tray firmly attached to the sailboard, the system can easily be exchanged and converted at any time so that one system can be used for several sailboards. This is particularly useful for those building their own sailboards. The lack of any mechanisms allows smooth operation. <IMAGE>
Patent DE-3313067-A1 (DE)
Title: Arrangement for processing the scanning signal in waviness, in particular roundness measuring instruments
Inventor: GRUBER ENGELBERT
IPC: G01B21/20
Filed: 1983-04-12
Abstract: In roundness measurements, the scanning signals which are picked up from the surface of the workpiece are fed via filters to a computer in order to determine the roughness, the roundness and shape. In such arrangements, defective true running of the plane table, e.g. due to displacement of the lubricant film in the bearing, enters directly into the result as a measuring error. Furthermore, in the event of a new analysis using another filter a renewed pick-up of measured values is required. Again, the filtering of the scanning signal depends on the speed of the test spindle. According to the invention, the disadvantages named above are avoided by storing the test signals unfiltered as digital values in a memory and filtering them later via a D/A convertor, a filter and an A/D convertor. The result is thereby rendered independent of rotational speed. If the profile of the rotary table is scanned using a 2nd sensor, the logged state of the table can be compared therewith and any true-running errors present can be eliminated. <IMAGE>

Patent DE-3404137-A1 (DE)
Title: Thermoelectric configuration having foreign-layer contacts
Inventor: DAHLBERG REINHARD DR
IPC: H01L35/32
Filed: 1984-02-07
Abstract: The object of the invention is to improve the efficiency of Peltier elements and thermocouples. The solution proposed consists in designing a thermal shank from two separate and unequally annealed parts in such a way that said parts have a multiplicity of contact points with one another. Said contact points are electrical and thermal contact resistances connected in parallel and having a foreign layer. The foreign layer of the contacts is thinner than 1 . 10<-6> cm, so that its electrical conductivity is enhanced by means of the wave-mechanical tunnel effect. The diameter of the contact points is so small that the temperature difference between the two parts of the thermal shank drops predominantly in the foreign layer. Thus the foreign layer becomes the active thermal shank of a Peltier element or thermocouple, whose efficiency is enhanced as a result of the extreme fields in the foreign layer. Figure 2 of the description is a typical illustration of the thermoelectric configuration having foreign-layer contacts 3. <IMAGE>
Patent DE-3406065-A1 (DE)
Title: Hair curler
Inventor: KUCH WALTER
IPC: A45D2/32
Filed: 1984-02-20
Abstract: The hair curler illustrated is formed by a conventional curler core (21) and a curler holder (22). The curler core (21) is constructed so as to be rotationally symmetrical about a curler axis and, in the centre between its ends (7, 8), is shaped concavely following a rounding curve for adaptation to the curvature of the scalp. Mounted on its outer surface are nipple-type elevations (9) which engage between the curled-on hair. The curler holder (22) has a rod-shaped back part (23) with S-shaped support legs (24) located opposite one another and the finger grip (25) constructed as a gripping piece. If said parts are of integral construction, they may consist of an elastically resilient rigid plastic. Individual parts made of different materials, for example, can also be joined together. When the hair has been curled, the curler holder (22) is fitted radially from the outside onto the curler core (21), the support legs (24) engaging on the curler core over the hair curl (11). The outwardly projecting support feet (26) hold the curler core (21) with spacing from the scalp. Pressure points on the scalp are thus avoided as well as local overloading and damage to the hair. <IMAGE>

Patent DE-3430839-A1 (DE)
Title: Magnetic levitation train
IPC: B60V3/04
Filed: 1984-08-22
Abstract: If trains are provided with magnetic levitation, they reach very high speeds. However, this also requires a very high degree of lateral stability as a securing factor against side winds. For this, surfaces in the manner of the fins of fish are to be additionally installed on the roof of the magnetic levitation train and these fins are to be electronically controlled taking into account the pressure of the side wind and the speed of the train. Likewise, some of the fins should always deflect the wind to the left and some other fins should always deflect the wind to the right of the direction of travel in order to secure lateral stability. It should be possible for short cars to drive from car ramps transversely with respect to the direction of travel of the train onto special coaches and to be protected by a lowerable cover. For this purpose, inflatable arches are to curve forwards from the roof like balloons after being lowered and, together with curved-forward balloons which have also been inflated from the floor, are to hold the vehicles so that very rapid loading and unloading on the other side of the coach is possible.
