Title: Three-phase transformer
Inventor: WAASNER BRUNO DIPL ING
IPC: H01F27/245
Filed: 1987-08-18
Abstract: There is a three-phase transformer whose core 1 is composed of laminated cores 10, 11 with the formation of joints 12 and which supports one coil 2, 3, 4 each on three limbs 7, 8, 9 which are connected by yokes 5, 6. It is desirable in this case if the laminated cores on all joints are designed so as to be non-vibrating (non-oscillating) or hum-free despite the coils. This is achieved by placing one coil 2, 4 each on one limb 7, 9 of an L-shaped laminated core 10 and the third coil 3 on one limb 8 of a T-shaped laminated core 10, the limb 8 of the T-shaped laminated core 10 projecting between the transverse pieces of the two L-shaped laminated cores 11 and the transverse piece of the T-shaped laminated core 10 being arranged between the limbs 7, 9 of the two L-shaped laminated cores 11, and if weldings 15, 16 of the joints 12 are provided between the laminated cores 10, 11 on the outer sides of the yokes 5, 6 facing away from the coils 2, 3, 4. All weldings are arranged remote from the coils, and the latter are not damaged by producing the weldings. <IMAGE>

Patent DE-3801631-A1 (DE)
Title: Security containers for water sports participants
Inventor: HEITZ WALTER-HELMUT
IPC: A45C11/22
Filed: 1988-01-21
Abstract: It is normal in water sports to use closed buoyant bodies to keep keys secure. In this case, the keys hang on the buoyant body, and in the case of a plurality of keys a bulky volume soon results. Moreover, near salt water iron keys run the risk of rusting. If keys fall into the water during the dark together with a conventional buoyant body, they are certain to be lost if only the slightest current prevails. In the novel floating and portable security container, the keys are kept inside the container. The container always remains capable of floating and being carried, even when it is open and the keys are outside attached to the container. The drying agent situated in the capsule protects the contents against the formation of rust or the action of moisture. Should the container fall into the water, it automatically transmits light signals. It is, in addition, constructed as a pocket lamp (torch) with a finger contact switch.

Patent DE-3803700-A1 (DE)
Title: Gear wheel
Inventor: SCHNEIDER HERBERT DIPL ING
IPC: F16H55/18
Filed: 1988-02-08
Abstract: Known gear wheels, especially those used in synchronising mechanisms in rotary piston superchargers, have the disadvantage that they give rise to severe noise owing to the pulsating delivery of the charger, because of radial play. The new gear wheel is distinguished by the fact that at least one gear wheel is formed by two gear wheels connected to one another with a predetermined angular offset by an elastomer layer, thereby minimising the radial play. Gear wheels of this kind are used in machines in which gear mechanisms can be used, especially in rotary piston superchargers.

Title: Pressure and conveying screw for mincing machines
Inventor: HAACK EBERHARD DR ING
IPC: B02C18/30
Filed: 1988-07-13
Abstract: The invention relates to pressure and conveying screws for mincing machines and for comminution machines functioning according to the mincing-machine principle. By means of the novel configuration of the pressure and conveying screw, a pressing effect is achieved on the material being processed in such a manner that a pressure pulsation results which is derived from the pressure of the mass of the conveying and the splitting-wedge effect of the splitting wedges arranged at the end on the inclined plane of the last screw turn. The said splitting wedges effect an additional compaction of the material being processed, and the conveying and comminution process is positively influenced.

Patent DE-3904961-A1 (DE)
Title: Safety device
Inventor: SIEP EWALD
IPC: E05F5/04
Filed: 1989-02-18
Abstract: A safety device for a door has a bolt (20) which is mounted pivotably about a horizontal axis. Secured on the bolt (20) is a lever (21) which, in a first pivoting position, permits a single closure of the door. After the door has been closed, the door frame (5) pivots the lever (21) into a second pivoting position. When the door is opened again, the lever falls automatically from the second pivoting position into a third pivoting position in which the lever blocks the closure of the door and thus prevents inadvertent slamming of the door. In the first pivoting position, a flap (26) secured on the bolt (20) covers the door lock (9) so that the lever can be brought into the first pivoting position only when the door key (10) has been removed. <IMAGE>
Patent DE-3909585-A1 (DE)
Title: Doorlock with automatic intrusion protection by latch retention and bolt advance
Inventor: DROSTE DIETER FRHR VON
IPC: E05B59/04
Filed: 1989-03-23
Abstract: The invention relates to a doorlock which affords increased intrusion protection by means of a retained latch together with automatic locking. Figure 1 reproduces the main features for a mechanical solution. By means of this mechanism, the automatic locking in particular, but also the latch retention, are achieved. During the opening of the door, which can take place only via the actuation of the pawl or locking mechanism via the lock cylinder, the bolt, which has been advanced one catch position, is pushed back and, simultaneously with the release of the latch retention, the bolt advance is pretensioned again. When the door is pulled shut, the latch is then pressed back again mechanically. At the same time, the latch triggers the pretensioned locking mechanism which locks the lock automatically (first catch position). The trigger point of the mechanism is adjustable. The latch is likewise retained and can be moved only via the pawl or the lock cylinder. If opening by means of the pawl is to be prevented, the bolt must be brought into the second catch position by means of the key. Opening is then possible only with the key. An additional cylinder-protection device ensures that, if the lock cylinder is broken out, the lock is blocked so that it can no longer be opened from outside. <IMAGE>

Title: Fibre=optic scintillation element - of cerium doped quartz glass fibres for ionising radiation detector
Inventor: HEMING MARTIN DR
IPC: G01T5/08
Filed: 1989-06-22
Abstract: A scintillation element for a fibre-optical ionising radiation detector consists of 5-1000 (pref. 10-1000) cm long fibres of Ce(3+)-doped quartz glass contg. at least 95 wt.% of SiO2. ADVANTAGE - The fibres allow construction of large area or large volume detectors with high position resolution. The Ce(3+)-doped quartz glass has very short dead times due to the very short decay time (less than 100 ns) of Ce(3+) ions (useful in high radiation fluxes and high energy physics experiments with high repetition frequencies), has scintillation yields similar to those of the best known scintillation glasses, has good transparency for scintillation photons, has good radiation resistance and has increased service life since Ce enhances defect healing.
