Patent DE-4222949-A1 (DE)
Inventor: ROLFF RANDOLF DIPL ING
IPC: H02P6/14
Filed: 1992-07-11
Abstract: The d.c. motor has stator coils (L1-L4) to which commutation signals are successively applied via switches (S1-S4). The commutation signals are generated by a PLL circuit (17) which receives a pulsed signal (U4) depending on the rotor frequency which is taken from a stator coil (L1). The PLL circuit (17) generates an output voltage (U5), the frequency of which corresponds to a whole multiple of the rotor frequency. This signal is taken to a counter (35), the status of which is decoded by a decoder (36). The commutation signals are thereby successively generated, their frequency and phase being automatically matched to the current rotor frequency.
Patent DE-4231825-A1 (DE)
Inventor: WIRTH HEINZ
IPC: B65B27/12
Filed: 1992-09-23
Abstract: What is proposed is a baling press (1), especially for the compaction of packaging material, such as cardboard, plastic foils or the like, which comprises in a conventional way a compaction chamber (2), a ram (6) and at least one tying means (7), such as bands, cords, etc.. According to the invention, a proposed bailing press has no need for so-called band lifters or pulling hooks in order to convey upwards on the ram side the tying means guided in the previous way along the floor of the compaction chamber. This is achieved in that, during the entire compaction operation, the tying means are guided upwards along the front side (10) of the ram (6), the lower deflection means (12) forming a releasable guide device. <IMAGE>

Title: Method for driving an electromagnet
Inventor: STRAUS KLEMENS
IPC: F01L9/20
Filed: 1993-06-16
Abstract: The invention relates to a method for driving an electromagnet by means of which a hydraulic valve, in particular, can be operated. In the case of a known drive method for an electromagnet, the latter is initially driven, during an excitation phase, with a switching-on signal, and is subsequently driven with a clock signal at such a frequency, and with pulses of such a time duration, that a mean holding current flows. It is now provided according to the invention that the electromagnet is driven before being switched off by a permanent signal of such time duration that the current flowing through the electromagnet assumes a maximum value. In consequence, the scatter in the current level at which the electromagnet drops out can be reduced.

Title: Process and apparatus for purifying hydrochloric acid contaminated by halogens such as bromine and iodine
IPC: A62D3/115
Filed: 1993-06-24
Abstract: The clean-up of flue or combustion waste gases gives rise, as a potentially useful material, to hydrochloric acid which, however, can be contaminated by halogens such as bromine and/or iodine. If these contaminants are not compatible with the intended re-use of the hydrochloric acid, they have to be removed from the hydrochloric acid. The novel process or apparatus shall combine a high degree of purification with a minimum number of process steps or hardware requirements while minimising the safety and environmental problems. The bromine- and/or iodine-contaminated hydrochloric acid is passed through an electrolyser (5) where these contaminants are electrolytically oxidised to Br2 and/or I2; subsequently these halogens are desorbed from the hydrochloric acid. The apparatus comprises an electrolyser (5), an exit line (8) leading to a desorption column (10), a line (14) leading from the desorption column to a condenser (18) and a subsequent separator (22). <IMAGE>

Title: Device for radiation protection shielding of the water surface during the cutting of irradiated reactor parts under water
Inventor: NESCHANJAN NESCHAN PROF DR
IPC: G21F1/00
Filed: 1993-09-21
Abstract: The invention described is based on the object of producing a flexible radiation protection cover which floats freely on a water surface and reduces the radioactivity, which prevents the floating of the irradiated particles directly to the surface during the cutting of irradiated reactor parts and thus reduces the contamination of buildings, devices and personnel in the reactor chamber or dismantling ponds located in the vicinity, and simultaneously permits the unimpeded use of robot systems and further elements of suction and filter systems at any desired point of the pressure vessel. This problem is solved according to the invention in that, before beginning the dismantling work, a specific quantity of granular and spherical materials is poured onto the water surface of the reactor pressure vessel or of a stationary dismantling pond. The material is a mixture of two components:   The first component is a material or a plurality of materials which have a high shielding capacity against radioactive radiation. The second component is a material or is a plurality of materials which has a very low specific gravity.   Both components are mixed in a ratio such that the individual granular and spherical particles immediately float on the water surface and thus form a closed radiation protection cover. The thickness of the cover is determined by a computer in accordance with the desired effect. The ... Original abstract incomplete. <IMAGE>

Title: Crankshaft
Inventor: POESCHL GUENTER
IPC: F01B9/02
Filed: 1993-09-29
Abstract: A crankshaft (10) is manufactured in one piece from a ceramic material by a shaping process, e.g. slip casting, which does not require any subsequent further shaping. The one-piece design of the crankshaft (10) and the use of a ceramic material make it particularly rigid and easy to manufacture. Only in the region of journals (18) and of a bearing seat (22) for big-end bearings (24) does the crankshaft (10) have to be finished by grinding. The crankshaft (10) is preferably shaped in such a way that undivided big-end bearings (24) can be slid onto it. The crankshaft (10) is preferably balanced by introducing molten metal into a cavity (14) in the crankshaft (10) and then allowing it to solidify. <IMAGE>

Title: Method and device for measuring and evaluating the inclination of a vehicle
Inventor: KOLB HANS DR
IPC: G01C9/06
Filed: 1993-10-29
Abstract: The device presented here for detecting the inclination of a parked vehicle is very small in terms of its geometric dimensions and can be mounted on an electric circuit board like an electronic component, especially since precise alignment of this sensor is not required. The method of measurement is self-adjusting and is very simple in its execution and yet efficient. It has been possible to achieve this by virtue of the fact that the continuously detected measured values of the inclination are assigned by means of membership functions to specific fuzzy sets in such a way that the occurrence of an alarm situation is detected in a very simple way and can be distinguished unambiguously from the situation in which the vehicle is oscillating. This method and the described sensor are principally suitable as a supplement to a basic alarm system for motor vehicles of all kinds in order to prevent, or make more difficult, a possible theft of the vehicle.
