The invention relates to an intrusion alarm system with a central intrusion alarm station and an operating unit which can be connected to the central intrusion alarm station. Such operating units must be designed to be very rugged for protection against sabotage attacks and environmental influences, and thus be very costly. The invention is based on the object of creating an intrusion alarm system...

A spray bar unit (1), fitted to an agricultural tractor, has sensors (S1, S2) fitted to the ends and these monitor the height (A) of the spray head above the ground level (F). The signals from the sensors are received by an on-board electronic controller (11) that identifies an error in required height and a difference in height between the ends. Corrective signals are applied to a hydraulic unit ...

A process and device are disclosed for measuring and determining the fluorescence feedback of algae in order to determine the density and vitality of the algae by means of exciting light, the fluorescent radiation of the tested plants or biomass being detected. The object of the invention is to develop a process and device that allow the algae density, i.e. the light attenuation in a sample, and t...

A method and apparatus for determining the hydraulic isolation of layers in an earth formation. The characteristics of various interfaces between the materials in the borehole are evaluated. An acoustic investigation is performed by directing an acoustic signal at a radial segment of the borehole. The signal passes through the casing and the fill material and produces a resulting signal which has ...

A sit-up exercise belt adapted to be placed under and around a corner of a mattress in such a way that a person can perform sit-up exercise by hooking and restraining the feet under the belt during exercise. The sit-up belt comprises a length adjustable belt (1) being connected at both ends to a trapezoid belt support member (4) which is adapted to be placed under the corner of the bed. A bar memb...

A fluoropolymer-containing powder coating product comprising the fluoropolymer and a thermoplastic resin which is compatible with the fluoropolymer in the melt, particularly a powder coating product comprising poly(vinylidene fluoride) and a methyl methacrylate homo- or copolymer, can be prepared without the necessity for cryogenic grinding if the material fed to the grinding step is a particulate...

In disc brakes, disturbing noises, such as whistling or squealing, occurring during braking operations can be prevented if the brake shoe, to be pressed against a brake disc by a pressure member, for example a hydraulically actuated piston, is taken along in the circumferential direction of the latter as soon as the brake shoe comes into contact with the brake disc, and is laid against bearing fac...

A process for the production of particulate expandable styrene polymers which have a very low benzene concentration is described using perketal and/or monoperoxycarbonate polymerization initiators. The styrene polymers produced according to the invention can be foamed to give foamed particles and molded, if desired.

The invention relates to a measuring and alignment device for a cylindrical grinding machine, with a measuring arm fastened to a grinding head and partly surrounding at a distance the roller to be ground.
