Inventor: KAMMERLANDER KARL ING GRAD
IPC: H04B7/26
Filed: 1980-03-27
Abstract: 1. A mobile radio network with overall network synchronisation, consisting of a number of radio concentrators (FUKOs) are arranged side by side in the manner of a cellular system with overlapping radio ranges (1, 2, ..., 7), wherein a firmly determined number of radio ranges directly adjacent one another form a radio range group (FGB), all the frequency channels available being repeated in each group, and wherein furthermore the frequency distribution plan for the radio concentrators (FUKOs) is so determined that common channel interference in the particular radio range including an extended edge zone is largely excluded, and wherein at least the signalling is carried out in digital form between the stationary radio concentrators (FUKOs) and the mobile subscriber stations by means of organisation channels (OK) which are designed for duplex operation and have a frame structure, characterised in that overall network synchronisation a radio range (4) spatially in the central zone of the radio network (FN) emits the main reference FUKO by means of its radio concentrator (FUKO), to which main reference FUKO the FUKOs of the radio ranges (1, 2, ..., 7), which surround said main reference FUKO, are synchronised in accordance with a concentric ring structure (O) having a hierarchy which is established from the inside towards the outside, in that in the direction of this ring structure, from the inside towards the outside, each FUKO is assigned at least one of the FUKOs, which are spatially directly pre-arranged relative to the former, as a reference FUKO.

Title: Conveyor belting of reinforced rubber - has reinforcement sheathed at both ends with low adhesion film to facilitate stripping
Inventor: STUDENSKI WALTER ING GRAD
IPC: B65G15/36
Filed: 1980-04-02
Abstract: In a conveyor belting of rubber, or rubber-like material, covering a reinforcing core of steel cords or woven fabric, at both ends of each length of the belting the core is sheathed for a short distance in a non-adherent, mouldable material which can withstand temps. of up to 180 deg.C. The sheathing of steel cord reinforcement pref. comprises high-viscosity non-vulcanised rubber. Fabric reinforcement is sheathed in a polyester material, pref. based on terephthalic acid and ethylene glycol.

Title: Waste water or clarifying sludge filtration - esp. through peat, to deposit solids, and pressing to expel water (FI 30.10.80)
Inventor: RAITA TAPIO A
IPC: C02F11/122
Filed: 1980-04-30
Abstract: In treating waste water or clarified sludge after waste water pre-processing, the waste water is filtered through a filter-material, e.g. peat, to deposit the solids in the filter material. The filter material, (5), together with the deposited solids, is exposed to pressure surges and is pressed so as to expel the water absorbed. One or more additives, e.g. CaO, CaCO3 or ash, can be added to the waste water before or during filtration. Thus, CaO raises pH and helps to destroy pathogenic bacteria and ash causes bonding of N present as NH3. Soil fertiliser material is obtd. The plant requires no centrifuges, etc. and the separated waste need not be composted. Natural nutrients in waste water can be retained.

Title: Monitoring sets of bricks during manufacture and packaging - involves deflecting sensors and failure signal switch evaluation
Inventor: STANKOVICC-GANSEN MARYAN
IPC: B07C5/34
Filed: 1980-06-13
Abstract: Sensors are distributed over the width of each set. The sensors are deflected by bricks with which they come in contact until they reach a normal position. A switch associated with the sensors outputs a failure signal if one or more sensors deviates from the normal position. A failure signal analyser permits a fault to be diagnosed if the failure signal occurs and region between the leading and trailing edges of the block set is in the sensor zone.

Title: Servo control for mixer drum - is based on temperature-difference and has schedule evaluating and converting parameter into pulse of given width
Inventor: JANSEN HANS-JUERGEN
IPC: G05D23/13
Filed: 1980-07-04
Abstract: The servo control system regulates a mixer in a heat regulating system. The response time is controlled via the speed of adjustment of the mixer. The speed is a function of the temperature difference between the reference value and the actual value of the offset temperature. The servo control unit and hence the mixer valve is adjusted in accordance with a temperature difference schedule and not by continuously switching the servo motor or by equally long switch-on phases. The temperature difference is evaluated and converted into a pulse of a given pulse width. The servo unit is switched as a function of this pulse width.

Title: Analog/digital converter
Inventor: TAKEUCHI SUMIO
IPC: H03M1/10
Filed: 1981-02-17
Abstract: For a fast analog/digital converter comprising a plurality of A/D converters, it is proposed to supply each A/D converter (4, 6) with a clock signal (18) having a different phase angle in order to increase the equivalent sampling frequency. To maintain the correct phase relationship, a reference signal, for example a linearly rising sawtooth signal (18), is used and a variable delay circuit (26) can be used for eliminating errors due to different electrical characteristics of the individual A/D converters. The desired phase correction is carried out in single steps and automatically by using a processing unit (20) before the analog input signal to be converted into digital format is connected to the analog/digital converter. <IMAGE>

Title: Device for signalling adjustment processes
Inventor: KROEMER GUENTER DIPL ING
IPC: G01D5/02
Filed: 1981-05-20
Abstract: As a device for signalling adjustment processes on an adjusting device which exhibits an actuator which is displaceable on a threaded section, a second threaded section is provided which has a measuring element the pitch of which is a multiple of the pitch of the actuator so that, when the actuator is adjusted, the measuring element is displaced by a multiple and the adjustment process becomes clearly recognisable. To transmit the longitudinal displacement, the measuring element can be coupled to a potentiometer which is located in the circuit of an indicating device reproducing the adjustment. However, this circuit can also be connected to a control device in which the detected longitudinal displacement can be processed as input variable. The device proposed can be used in adjusting devices for control systems, for example for controlling injection pumps.

Title: Process and apparatus for the impregnation of wet-pretreated fabric webs, especially knitted fabrics, with dye liquors and/or chemicals
Inventor: MEISEN KLAUS
IPC: D06B3/18
Filed: 1981-05-20
Abstract: The invention relates to the impregnation by means of dye liquors and/or chemicals on wet-pretreated fabric webs, especially on knitted fabrics, without the need for intermediate drying, that is to say to wet-in-wet impregnation. For this purpose, the still wet fabric web is first squeezed with high squeezing pressure to a predetermined residual moisture, is then guided through a small-volume impregnating liquor and subsequently is once again squeezed with a lower squeezing pressure to a predetermined amount of residual moisture and wound up. For this purpose, as regards the apparatus, an impregnation trough (3) is preceded by a first squeezing unit (1) and followed by a second squeezing unit (2) in the direction of run of the fabric web (8). Arranged between the two squeezing units (1, 2) are guide rollers (4, 5, 6) which, in order to form an impregnating gap (9), are incorporated into the impregnation trough (3) together with a displacement body (13), arranged between the guide rollers, and the trough bottom (10). The fabric web (8) deflected by the guide rollers (4, 5, 6) runs through the impregnating gap (9) between the guide rollers, the displacement body (13) and the trough bottom (10) and consequently an economical volume of impregnating fluid. <IMAGE>
