Title: Vacuum system for the drying of ceramic mouldings
Inventor: GRAEF PETER ING GRAD
IPC: B28B11/24
Filed: 1981-02-09
Abstract: Vacuum system for the drying of ceramic mouldings by means of suction fans, by feeding drying air of between 50 to 180 DEG C to the material to be dried. In particular, the drying system is characterised in that a vacuum of at least 130 mm water column prevails in it. In optimum drying air, the air humidity is to be between 20 and 30 %, and furthermore a high air throughput must prevail in the drying system, that is to say the throughput of drying air must be at least 300 times the volume of the drying space. Such drying systems can be used both as chamber dryers and as channel dryers. The vacuum in the vacuum-drying system is generated by means of a simple constructive measure, in that the diameter of the suction pipe for the waste air is approximately 2 to 4 times the diameter of the intake pipe.

Title: Device for protecting objects against unauthorised taking away
Inventor: JANK WILHELM
IPC: G08B13/14
Filed: 1981-05-14
Abstract: In order to protect objects against unauthorised taking away, a radiation field is produced in the region being monitored. Locking devices are fitted to objects to be protected, which locking devices have a sensor (12), which reacts to the radiation field, and a signal transmitter (13). When the locking device is closed, the output signal from the sensor (12) is supplied via a locking contact (21) to the signal transmitter (13) which is in consequence prevented from producing an alarm signal. If the connection between the sensor (12) and the signal transmitter (13) is broken (interrupted), then the signal transmitter (13) is changed into the alarm mode. An alarm is produced whenever the locking device leaves the radiation field produced in the monitored region or if the locking device is detached in an unauthorised manner. <IMAGE>

Title: Aluminium chloride/hydroxide hydrate complex as a medicament for phosphate binding and process for its preparation
IPC: C01F7/57
Filed: 1981-12-03
Abstract: In some diseases, in particular in kidney disorders, absorption of the phosphate taken up with the food must be largely avoided. The aluminium chloride/hydroxide hydrate complexes according to the invention bind phosphate to a high extent in the intestinal tract and therefore largely prevent absorption of the phosphate. The aluminium chloride/hydroxide hydrate complexes described can therefore be used as medicaments for phosphate binding.
