Title: Remote switching of alarm system - by comparing decoded signal with given code and in case of coincidence generating switching signal
Inventor: WEIN RUDOLF
IPC: G08C23/04
Filed: 1978-11-17
Abstract: The alarm system, e.g. in a car, is switched by signals transmitted over sound, radio or light, esp. infra-red light channels. A signal is sent out from one point and received at another, where a switching signal for the system is generated. Before transmission the signal is coded in a certain code, and the received signal decoded and compared with the correct code. When the codes coincide, a switching signal is generated. If the codes do not coincide an alarm signal may be generated. An alarm signal may be generated if a given time is exceeded between appearance of a received signal and generation of a switching signal.

Title: Microwave thawing oven for pastries etc. - thawing food rapidly by heating centre with microwaves and cooling surface with cold air
Inventor: FRITZ KARL DR
IPC: H05B6/80
Filed: 1979-03-21
Abstract: The thawing oven passes a cold air stream over the pastry. The cold air is cooled in a conventional manner. The microwave radiation enters the oven via two opposing windows, and has the same phase and amplitude at both windows. The max. of the two radiation sources can be displaced by controlling phase and amplitude externally. The radiation sources are positioned such that a relatively uniform temp. increase occurs in the entire pastry except at its surface which is held at a relatively low temp. Part of the cold air is used to cool the microwave oscillator. Any absorbant parts likely to interfere with thawing are removed.

Title: Protective circuit for plants against destruction by snails etc. - has current-carrying strip creating potential difference between body of snail and soil
Inventor: ERNST KARL AUGUST DR ING
IPC: A01G13/10
Filed: 1979-05-05
Abstract: A protective system for useful and ornamental plants prevents them from being eaten by snails, slugs etc. The process used is based on the fact that snails are very sensitive to an electrical potential drop across the body. The plants are surrounded by an electrical barrier, which cannot be penetrated by the snails. The potential difference across the body of the snail is brought about by the electrical field strength in the air and the soil. The plants are surrounded by a conducting strip, which carries a current. The snail is forced to come into contact with the potential of the soil and the potential of the strip. The potential can be pulsating, uniform or wave-shaped. The power is supplied by a dry battery (5).

Title: Nitrification-denitrification of waste-waters - using activated sludge, with anaerobic denitrification of a portion then returning to aerobic zone
Inventor: MATSCH LADISLAS CHARLES
IPC: C02F3/12
Filed: 1979-06-18
Abstract: The known activated sludge method of purifying waste water in which (i) waste water contg. N-cpds. is mixed in an oxic zone in the presence of C cpds. with an O2-contg. gas and activated sludge contg. C-consuming and N-oxidizing bacteria so that N-cpds. are nitrified; (ii) a nitrified, oxygenated mixed liq. is discharged from the oxic zone and passed to a solids concn. zone to concentrate the solids from the liq.; (iii) a major portion of the concd. solids is returned to the oxic zone as the activated sludge; and (iv) where the total mean residence time of solids (SRT) is not 2 days is improved as follows: (a) nitrified oxygenated liq.-solid is withdrawn and passed to an anoxic zone with a vol. flow rate 1/2 the vol. flow rate of nitrified oxygenated mixed liq. entering the solids concn. zone; (b) the nitrified oxygenated liq.-solid in the anoxic zone is kept under anoxic conditions for 0.4-36 hr. so that the liq.-solid is denitrified and N2 gas is formed; (c) the N2-contg. gas is released and the denitrified liq.-solid is returned to the oxic zone. Integrated biological process not only effectively removes N-cpds. (and can be adjusted to remove phosphate as well), but also requires reduced tankage and power consumption.

Title: Magnetic inductive flow meter - has magnetic field length compensation of auxiliary electrodes supplied via impedance transformers or amplifiers
Inventor: HAUG PETER
IPC: G01P5/08
Filed: 1979-12-13
Abstract: A magnetic inductive flowmeter has a measurement tube carrying a coil and opposed measurement electrodes measuring the voltage induced in the electrically conducting liquid flowing through it. The length of the magnetic field exerts a minimal influence on the measurement which can be performed for liquids whose conductivity varies differently with temp. and flow.

Title: Rotary position control system - has magnetic tape generating incremental signals and with built-in magnetic brake
Inventor: REEDER WILLES W
IPC: G05B19/23
Filed: 1980-03-14
Abstract: The digital control system is designed to provide rotary position control based upon a specified number of revolutions plus a number of degrees. The system uses a rotor (100) coupled to the shaft of the machine tool. A magnetic tape (18) has recorded bits that correspond to each increment of rotary motion. The bits are read by a magnetic pick-up (12) and are fed to separate counters that totalise the full revolutions and the degrees. Digital circuitry monitors the counter values to initiate a stop and hold action. A magnetic brake unit (106) is activated to hold the shaft in the correct position.
