Patent DE-3039141-A1 (DE)
Title: Composite mast for lighting tower - has short cylindrical sections overlaid with filled resin outer coating
Inventor: SCHELZKE ERHARD DR ING
IPC: E04H12/02
Filed: 1980-10-16
Abstract: The mast of the type used for lighting towers warning posts, etc., is designed for high strength and long life. The mast is formed with an inner core provided by a number of short cylinders (2) of either steel or profiled plastic that are laid end to end. The top end of the mast is formed by a longer cylinder (9) that locates within the top section. In order to provide strength coupled with flexibility, the outer surface is covered with an epoxy filled resin compound. An alternative form uses a fibre glass outer coating wrapped around the cylinder stack.

Title: Automatic switch for neon lighting, indicator etc. - monitors daylight and has timer defining given period of day
Inventor: FUJINO ETSURO
IPC: H05B37/02
Filed: 1980-11-21
Abstract: The switch has a timer producing an output signal during a given period of the day. A photodetector produces an output signal dependent on light level and is connected to the input of a control circuit. A logic circuit combines the output of the timer with the output of the control circuit. A load switching device switches a load depending on the binary state of the logic circuit's output. The control circuit, the timer, the logic circuit and the load switching device are connected together such that the load is switched in when the light level drops below a min. and vice versa.

Patent DE-3049088-A1 (DE)
Title: Archimedean screw removes crystals deposited from electrolyte - continuously fed through externally cooled container
IPC: B01D9/00
Filed: 1980-12-24
Abstract: Crystals are recovered from used plating electrolyte continuously fed through a large inclined container whose lower closed section is surrounded by a continuously liq. cooled jacket. Electrolyte enters the container through a motor-driven hollow axial shaft with holes at its lower end. Mounted on the shaft is an Archimedean spiral which as it is rotated by the same motor stirs the electrolyte and also moves deposited crystals past the electrolyte surface to the open upper end of the container from which they drop into a receiver. Slotted into the carved strip forming the spiral are brushes or other scrapers to remove crystals from the container wall. Used for treating large vol. of electrolyte e.g. to recover iron sulphate from copper plating bath. The unit need not be stopped for cleaning, which is an unpleasant manual operation, a single motor operates both stirrer and extractor spiral, and heat transfer is not reduced by crystal build-up on the container wall. The top of the container may be heated to dry the crystals before ejection.

Features of the invention are that use is made of glasses which have a lower refractive index and are therefore cost effective, that the first lens is relatively spherical, and that the second air space has the form of a thin diverging meniscus.
Patent DE-3115057-A1 (DE)
Title: PLL circuit with a digital phase discriminator
Inventor: CHARLES GERARD DIPL ING
IPC: H03D13/00
Filed: 1981-04-14
Abstract: A PLL circuit contains a digital phase discriminator which outputs a first signal for controlling the PLL oscillator (VCO) when the input signal arrives during a first phase of the PLL oscillator, and a second control signal when the input signal arrives during a second phase. To determine the phase difference, a first bistable flip flop (FF1) is enabled in the first phase of the oscillator signal, set by the input signal and reset at the end of the first phase. During the second phase of the oscillator signal, a second bistable flip flop (FF3) is enabled which is also switched with the input signal. This triggers a timing element (DL) which outputs pulses of a duration which are equal to that of the second phase of the oscillator signal. PLL circuits are used in devices for reading data from memories with a mechanical drive mechanism. <IMAGE>

Title: Two-wheeler with a single-wheeled cycle hitched up via a device
Inventor: PATSCH RAINER DIPL PHYS DR
IPC: B62K27/00
Filed: 1981-06-19
Abstract: The invention describes a device used to hitch up the rear part of a folding bicycle to a two-wheeler in the manner of a trailer.

Filed: 1982-04-14
Abstract: N-Methoxy-N-methylurethanes are prepared by a process in which first (1) hydroxylamine is converted with an alkyl chloroformate to the corresponding N-hydroxyurethane, then (2) this product is reacted with a methylating agent to give the N-methoxy-N-methylurethane, and finally (3) the N-methoxy-N-methylurethane is isolated. In this process, first, (1) while maintaining a certain temperature and a certain pH, (1.1) an aqueous solution of an inorganic hydroxylammonium salt is mixed thoroughly with (1.2) an equimolar amount of an alkyl chloroformate, then (2) while maintaining a certain temperature and a certain pH, (2.1) a mixture comprising (2.1.1) the reaction mixture obtained as described in (1), (2.1.2) a water-insoluble organic solvent and (2.1.3) a phase-transfer catalyst is mixed thoroughly with (2.2) a water-insoluble methylating agent which is soluble in the solvent under (2.1.2), and the resulting mixture is kept at a certain temperature for a certain time, and finally (3) any methylating agent still present in the reaction mixture obtained as described in (2) is destroyed, the non-aqueous liquid phase is separated off from the mixture thus treated, and the N-methoxy-N-methylurethane is isolated from this phase by stripping off the solvent. A relatively pure product is obtained in high yield.

Title: Wide-beam search radar with accurate angle determination and method for accurately determining angles
Inventor: BUTLER WALKER
IPC: G01S13/66
Filed: 1982-12-29
Abstract: In wide-beam search radars, accurate angle determination is achieved by using the angle measuring capabilities of a radar system, such as, for example, a monopulse radar. A target is determined by an external target device which establishes the position of the particular target. The search radar receives the directional information and aims its antenna in the specified direction and measures the angular displacement of any targets in the radar beam with respect to the antenna direction. The measured angular displacement is compared with a predetermined resolution in order to determine whether the particular target has been determined so that a tracking mode can begin.
