The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)

Title: Single step process for producing polyamines from NCO prepolymers.
IPC: C08G18/50
Filed: 1983-07-21
Abstract: Polyamines containing aromatic and/or aliphatic primary amino groups are produced by hydrolyzing an isocyanate compound in the presence of water, an insoluble basic compound as a catalyst and a water-miscible solvent in a single reaction step. The isocyanate compound has an NCO-content of from 0.5 to 40 wt % and is preferably a prepolymer. The (pH-) basic compound is substantially insoluble in both water and the organic solvents generally used in such processes. An isocyanate-reactive compound may also be included in the reaction mixture in an amount which is from 0.1 to 15 wt % (based on isocyanate compound). The hydrolysis reaction is generally carried out at a temperature from 50 DEG to 165 DEG C. in a manner such that the reaction mixture remains substantially homogeneous. The product polyamines contain from 0.19 to 20.3 wt % primary amino groups. These polyamines are particularly useful in the production of polyurethanes.
Patent ES-8406933-A1 (ES)
Title: Concrete mixer
IPC: B01F29/60
Filed: 1983-08-02
Abstract: The invention relates to a concrete mixer, particularly to a truck-mounted concrete mixer, comprising a drum and an actuatable additional mixer tool projecting into the drum from the bottom thereof substantially in the direction of the drum axis. A rotatably driven mixer tool of this type requires the employ of additional gearing, and a sealing assembly for the passage of its shaft through the drum bottom is very complicated and subjected to wear. In accordance with the invention, these disadvantages are avoided by the provision that the mixer tool is adapted to be moved in the axial direction. This permits a cylinder-piston unit to be employed as the drive source for the mixer tool. No gearing is required, and sealing as well as maintenance are simplified.
Patent ES-8405998-A1 (ES)
Title: Process for manufacturing semiconductor devices comprising an electrochemical-etching step.
IPC: H01L21/3063
Filed: 1983-09-08
Abstract: A procedure is described for electrochemically photoetching n-type and intrinsic compound semiconductors. The process involves applying a potential to the compound semiconductor while it is in contact with an electrolytic solution and irradiating the surface to be etched with light in a certain energy range. By suitable adjustment in the potential, electrolytic solution composition and light energy, the etch rate is made proportional to the light intensity. By suitable variation in light intensity and light-ray direction, various geometrical features can be made on the surface of the compound semiconductor. For example, a hole with straight sides can be made in the compound semiconductor by use of a light spot and parallel (collimated) light rays. An advantageous application of this process is the fabrication of a photodiode with a hole in the center for use in bidirectional communication systems and to monitor power output for optical communication sources. The advantage of this process is that no damage occurs outside etched hole so that a maximum area of the photodiode remains active for detecting incoming radiation. Another advantage of the process is that etching will stop where the material becomes p-type so that etching can be made to stop automatically at a p/n junction.
