Filed: 1980-11-11
Abstract: Mfr. of acicular goethite comprises adding divalent metal ions to ferrous salt soln., adjusting the soln. to pH more than 11, and oxidising. Acicular goethite formed is treated with surfactant, and dried. Acicular goethite obtd. is used for making microgranular magnetic powder having extremely improved saturation magnetisation characteristics. In an example, in 0.5l of water were dissolved 100g FeSO4.7H2O crystal and 1.34g NiSO4-7H2O, and 100g NaOH and 9.2q potassium chlorate as oxidising agent, and the whole vol. adjusted to 1.5l. The soln. was oxidised at 40 deg.C. The resulting gamma-FeOOH ppte. was washed with water until pH became less than 8, and then adjusted to pH 3 with N-H2SO4, and 1.1g of GAFAC-RE 610 (RTM) added and stirred for 30 min. The ppte. was dehydrated (at 600 deg.C), reduced (at 400 deg.C.) and oxidised (at 250 deg.C.). The resulting gamma-Fe2O3 powder exhibited Hc 400 Oe and specific surface area about 50m2/g.

Title: Colour signal processing device
Inventor: TAGUCHI SHINICHIRO
IPC: H04N9/793
Filed: 1981-02-27
Abstract: In the recording or pick-up mode of a videotape device, a colour signal (3.58 MHz) is subjected to a frequency conversion into a converted low-frequency colour signal (688 kHz) by a colour signal processing device. In the replay mode of the videotape device, the regenerated converted low-frequency colour signal (688 kHz) is converted back into a colour signal of the original frequency (3.58 MHz) by the colour signal processing device. The signal (3.58 MHz or 688 kHz) conducted through a switch circuit is subjected to a gain control by a colour signal amplifier and input into a balanced or push-pull modulator. A conversion signal (F03 = 4.27 MHz) is also fed into the modulator. The output signal of the push-pull modulator is supplied as frequency-converted signal (688 kHz or 3.58 mHz) via a low-pass filter or a band pass filter. The conversion signal (FO3 = 4.27 MHz) is obtained by the push-pull modulator as oscillation output signal (3.58 MHz) of a first voltage-controlled oscillator and divided output signal (f02 = 688 kHz) of a first voltage-controlled oscillator and divided output signal (f02 = 688 kHz) of a divider for dividing the output signal of a second voltage-controlled oscillator.

Title: Inclination balance for indicating the horizontal or vertical position and deviations from these positions by means of a closed electrically controlled optical display chain which extends over at least one entire side of the housing
Inventor: MOEBUS KONRAD
IPC: G01C9/06
Filed: 1982-03-09
Abstract: The invention relates to a switching tube for an inclination balance. In this switching tube (3), a spherically electrically conductive switching element moves, particularly a mercury pearl (6). When this switching element is moving, it is used for connecting a common contact (Sh) to individual contact areas (Sa-Sg). To increase the reliability and accuracy of indication, the switching tube exhibits a concave inner wall along which the switching element is intended to move. The individual contact areas (Sa-Sg) are arranged adjacent to the common contact (Sh) in the longitudinal axis of this concave inner wall. To determine the inclination position of points rotated through right angles from one another, the switching tube can be constructed to be horseshoe-shaped; the longitudinal axes of the arms of the horseshoe, in turn, are arranged at right angles to the longitudinal axis of the connecting elbow of the horseshoe. Both the two arms and the elbow connecting them then have in each case a concave inner wall with a common contact and individual contact areas adjacent thereto. <IMAGE>

Patent DE-3214281-A1 (DE)
Title: Separable xerographic copying set
Inventor: KOSCHE HORST H DR RER NAT DIPL
IPC: G03G7/00
Filed: 1982-04-19
Abstract: The material according to the invention is used to produce xerographic copies by transferring a toner image from a photo-conductive layer. In order to achieve sufficient toner adhesion, the toner is fused, by means of heating with rollers or by heat irradiation, into the surface of the material serving as the copy or the transparent original. Hitherto, transparent copies have only been produced from polyester films, where the biaxial stretching of the production process was cancelled by a heat treatment so as to prevent shrinking of the film during baking of the toner. Other films were unusable because of their thermoplasticity. Furthermore, the films had to be made antistatic so as not to attract dust. The copying set according to the invention comprises an image sheet, which serves as a copy, and an auxiliary sheet which removes the heat absorbed by the image sheet and at the same time is electrically conductive in such a way that electrostatic charges are conducted away from the image sheet. The image sheet and the auxiliary sheet pass through the copier together. They are joined together so as to be easily separable, and are separated after the toner transfer. Owing to the use of an auxiliary sheet, thermoplastic films, which used to stick in the copiers, or thin polyester films, which used to buckle, can be used. Because of the antistatic properties of the auxiliary sheet, electrical charges are conducted away from the copying sheet. In the pack, the auxiliary sheet, which is electrically conductive on both sides, covers the front and rear sides of the copying sheet. As a result, electrostatic charges on pulling out a copying sheet are prevented.

Title: Interference-resistant electronic emergency alarm
Inventor: HOECKER WOLFGANG DIPL ING
IPC: H04M11/04
Filed: 1982-04-20
Abstract: Interference-resistant electronic emergency alarm, whose circuit arrangement, if an emergency call is initiated from the telecommunications exchange line (La, Lb), is fed with a supply voltage (UV) corresponding to the respective switching state via locking switching elements (RRL, RRM, RRR), a parallel feed (PS) or a serial feed (SS). The power consumption of the circuit arrangement is minimised through the use of pulse-controlled relays (RAU, RGU, RMH; RRL, RRM, RRR) and temporary blocking of the clock circuit of the processor (MPR). The switching elements (RRL, RRM, RRR) are polarised relays whose contacts (RLK, RMK, RRK) are switched with a magnetic field when the trigger is actuated. The circuit arrangement contains a processor (MPR) which, following activation, disconnects any existing speech path to the telephone set (TA) by actuating the changeover relay (RAU) and which transmits dialling signals and identification signals via clocking of the circuit (NSI) according to the switched contacts (RLK, RMK, RRK) until it receives a call connected signal via the signal detection circuit (WE). It then releases the locking of the switching elements (RRL, RRM, RRR) by means of an output signal (RA) and connects a speech path to the telephone set (TA). <IMAGE>

Title: Method and device for determining the speed of an axis of rotation
Inventor: KUELLER HERBERT
IPC: G01P3/489
Filed: 1982-04-29
Abstract: In order to determine the speed of an axis of rotation that is coupled to an axis pulse generator (1), the period (Z2) of a number of cycles (Z1) prescribed as a function of the speed is measured. The speed is then yielded as the quotient of the number of cycles (Z1) and the period (Z2). A minimum period (Z2min) is prescribed for speed-dependent stipulation of the number of cycles, and the axis pulses (Z1) transmitted during this minimum period after the start of a timer initiated by an axis pulse are counted. When the next axis pulse is transmitted after expiry of the minimum period (Z2min), the actual period (measurement period Z2) is read off at the timer. As a result, the speed can be determined with high accuracy during a short measurement time. <IMAGE>

Title: Process for detoxification of combustion gases from fluidised bed combustion plants
Inventor: LEON ALBERT M
IPC: B01D53/50
Filed: 1982-06-07
Abstract: Sulphur-containing substances polluting the environment are effectively eliminated from the exhaust gas streams which are produced in a combustion system using a fluidised bed. The fluidised bed is formed from particulate material, for example limestone and/or dolomite, a condensation gradient being maintained in the vertical direction. Counter-current contact between the upwardly directed sulphur-containing combustion gas and the descending absorber material particles produces a concentration gradient in the vertical direction of the bed, that is a decreasing concentration of sulphur, sulphur dioxide and similar impurities towards the top and a decreasing concentration of calcium oxide and the like towards the bottom. In this manner, gases having decreasing sulphur contents are brought into contact with surrounding substances in which there are increasing concentrations of calcium oxide, so that an optimal elimination of the sulphur contents is ensured.
