Title: Process and device for biological waste water purification
IPC: C02F3/12
Filed: 1987-03-04
Abstract: In this process and this device, air and/or pure oxygen is passed into the waste water in an aeration tank in the presence of biomass which is immobilised on carrier particles, and the waste water is subsequently separated into purified water and activated sludge in a secondary sedimentation. Since the biomass in the core of the carrier particles dies off gradually, the invention provides acceleration and slowing-down devices which allow regeneration of the carrier particles. In this process, the carrier particles are accelerated and then slowed down, so that according to the kinetic energy which is set free, a compression of the carrier material in some parts and therefore a loosening and partial elimination of the dead biomass are achieved. The biomass concentration in the carrier particles can be controlled by changing the speed at which they leave the accelerating zone. (Figure) <IMAGE>

Title: Process and installation for the purification of waste containing phosphates, and for the biological elimination of phosphorus
IPC: C02F3/28
Filed: 1987-09-28
Abstract: For improvement of the phosphate redissolution taking place under anaerobic conditions, the treatment is conducted under anaerobic conditions, preferably in a settling tank, into which unsettled raw sewage and a return sludge from the secondary settling tank are introduced. The sludge retention time of the return sludge is generally over 5 hours, preferably 10-24 hours. In any case, the sludge detection time exceeds the hydraulic detection time. The new process can be performed by using most existing plants with relative small investment expenditures and provides a phosphorus elimination on the order of magnitude of 90%.

Abstract: An anatomically form-fitting, generally self-adjusting 
disposable absorbent garment (10), comprises a breathable 
elastomeric nonwoven laminar outer cover (12), resiliently 
stretchable preferably in a cross-body direction from 
about 20% to about 200%, including a pair of leg openings 
(18) front (13) and rear (14) waist sections together 
defining a waist opening, a crotch section (16) situated 
between the leg openings (18) and front (28) and rear (30)

20% to about 300%, providing cushioned, cloth-like gath­
erings of the garment about the body of a wearer.
Patent EP-0237171-A3 (EP)
Title: Inductance divider sensor
IPC: H03K17/95
Filed: 1987-02-03
Abstract: A method and apparatus for sensing the proximity of a target object includes a sensor inductor (L<sub>s</sub>, 38) connected in series with an identical reference inductor (L<sub>R</sub>, 36) between an input and ground to form an inductive divider network. The sensor inductor is positioned so that its inductance can be varied in response to the proximity of a target object (14, 40) while the inductance of the reference inductor remains constant. Voltage pulses are periodically applied to the divider network from a source (32, 34) and divide across the reference and sensor inductors in accordance with the ratio of the inductances, as varied or not by the presence of the target object. A detector (30) monitors the output of the divider network and provides a target status signal indicative of the proximity of the target object. For low-power operation, the detector circuit and conductive divider network are periodically and momentarily energized in synchronism. This enables configuration of a self-contained, leadless proximity sensor having a battery power source and an optical output.

Abstract: A container for transporting an accidentally 
severed limb 17 or other body part and keeping it cool to 
aid the success rate of replantation surgery comprising a 
suitcase-like openable container 2 made of aluminium 
sheet 4 with a heat insulating covering 5. To maintain 
the temperature of the container between 2°C and 6°C, a 
cylinder of carbon dioxide 19 is mounted in a holder 9, 
18 on the outside of the container and has its shut-off 
valve 20 connected to an injector nozzle 23 in the 
container. Carbon dioxide discharged by the nozzle 23 
produces dry ice in the container 2 to cool it. The 
flow of gas through the nozzle 23 is controlled by a 
thermostatic device which includes a spring 24 made of a 
shape-memory alloy which allows the nozzle 23 to be 
closed at temperatures below 2°C but which regains its 
strength at a temperature of 6°C to open the nozzle when 
the inside of the container has warmed up again to this 
temperature.

IPC: A01M29/16
Filed: 1987-10-15
Abstract: An apparatus for deterring birds comprises a carrier 
oscillator which is frequency modulated by a modulation 
oscillator (IC6), the signal being applied to a power 
amplifier (28) which drives a loud speaker. The 
oscillators are voltage controlled and their nominal 
frequencies are switched in a preselected manner by a 
binary divider (14) which controls the application of 
tuning voltages to the oscillators via gating circuits 
(IC1). A sequence generator (16) generates a random or 
preslected pattern of pulses which control a relay (RL1) 
via a trigger circuit (20) to apply power in an 
intermittent manner to the power amplifier (28). The 
result is periodic bursts of sound from the loudspeaker at 
frequencies and intervals which are sufficiently random to 
detcr birds from the surrounding area.

IPC: H04N7/16
Filed: 1987-10-23
Abstract: A multichannel signal distribution control 
system, such as a CATV system, providing a plurality 
of video signal channels wherein selected channels are 
obscured by random noise jammer signals. The signal 
distribution system includes multiple output ports, each 
port connected to a respective user or subscriber. The 
random noise jammer signal is provided by a band-limited 
noise source (58,60) and a signal translator (62A,64A;62B, 
64B;62C,64C) which provides a noise signal band 
corresponding to the frequency of the channel to be 
selectively disabled. The resulting noise signal is 
added to the signals for specific individual subscriber 
output ports (through switches 66A-66F) to obscure 
the signal on the selected channel of that individual 
subscriber. The multichannel signal distribution control 
system is controlled by signals provided remotely from 
a home office to each local jamming device by control 
signal superimposed on the multiple channel signal 
feed line (52) and received by a processor (70) for 
controlling the selective addition of noise signal.

Title: Laminates reinforced with polyurethane compositions
IPC: B32B5/18
Filed: 1988-08-02
Abstract: The inclusion of nucleophilic groups containing

substantially extensions of the pipework. The fiber suspension 
is treated in the ducts and thereafter the treated suspension is 
discharged from the ducts by feeding yet untreated suspension to 
the apparatus.  
     The apparatus includes a plurality of axially elongated 
treatment ducts (9) arranged in the form of a ring around an axis 
of rotation. The ducts are radially limited by filter surfaces 
(10, 11) and in the direction of the end walls divided by

shaft (12) inside casing (2). A feed conduit (4) for the pulp 
is arranged at one end of the apparatus and a discharge conduit 
(6) for the treated pulp at the opposite end thereof. The feed 
and discharge conduits are sequentially registrable with the same 
treatment duct.

Title: Demultiplexer with a circuit for the reduction of the waiting time jitter
IPC: H04J3/06
Filed: 1989-11-28
Abstract: There are time-division multiplex communication systems in which digital signals which are asynchronous with the pulse frame and consist of successive blocks whose beginnings are marked with sync words are inserted into the pulse frame. The resulting jitter of the sync words ("waiting-time jitter") is reduced by a circuit which derives from the clock of the received sync words a sync signal (SY) that exhibits less jitter than the clock of the received sync words. According to the invention, the circuit contains a measuring device which measures the time intervals (N) between the sync words, a filter (F) which takes the average (N') of the time intervals (N), and a signal generator (S) which forms the sync signal (SY) from said average (N') in such a manner that the pulse period of the sync signal (SY) is equal to said average (N').
