Title: Method for transmitting an encrypted analog speech signal
Inventor: BETZL HERMANN DIPL ING
IPC: H04K1/04
Filed: 1984-09-28
Abstract: In speech transmission there is often a requirement, particularly in telephone traffic for institutions at government level, to design the speech transmission so that it is interception-proof. High secrecy levels for interception-proof speech transmission of this type can essentially be achieved by means of digital encrypted signal transmission. The bandwidth required for this purpose, however, exceeds the bandwidth of the original analog speech signal. This additional bandwidth requirement is often not available. A method is proposed in which the original speech signal is sub-divided into a plurality of frequency sub-bands which, referred to the respective bandwidth of a frequency sub-band of this type, have approximately constant attenuation and transit delay characteristics. These frequency sub-bands are then encrypted at the digital level in such a way that the encrypted frequency sub-bands following their combination to form an encrypted speech signal can make do at the analog level with a bandwidth which corresponds to the bandwidth of the original speech signal. The transmission then takes place in the form of this encrypted analog speech signal. <IMAGE>

Title: Measuring arrangement for determining the optimum reaction between electromagnetic waves and gravitation, and method for evaluating this measurement for medical and biological applications
Inventor: MIEG PETER DIPL PHYS DR
IPC: A61B5/05
Filed: 1984-12-11
Abstract: Optimum reaction between electromagnetic waves and effects based on gravitation are produced in biological systems and in the human body by applying a swept UHF oscillation to the system or the body in such a way that the saw-tooth sweep voltage has a minimum slope of the wave front, the sweep frequency is approx. 160 Hz (or a multiple of this frequency), the swept UHF oscillation being in the region of 200 - 400 MHz, 400 - 800 MHz (or a multiple of these frequencies). The position of the range of effectiveness of these oscillations, and the optimum magnitude of the control voltage, whose ratio of fall time to rise time is at least 10:1 are determined in a special measuring arrangement. The latter consists of a control unit for generating the sweep voltage, a UHF sweeper, a wideband measurement receiver and a dual-trace oscilloscope for comparing the control signal to the AF output signal of the measurement receiver.

Patent DE-3541451-A1 (DE)
Title: Process for producing a negative image
Inventor: STAUFFER CRAIG M
IPC: G03F7/20
Filed: 1985-11-23
Abstract: In a first process step, a positive photo-etching base material is applied to the surface of a substrate. The photo-etching base material is exposed imagewise, through a mask, to actinic radiation, whereupon a carboxylic acid or other acid, soluble in a solution, forms on the exposed parts. Thereafter, the entire photo-etching base layer is subjected to a treatment with hot steam, which renders the acid formed insoluble in alkaline solvents and relatively insensitive to further radiation exposure. Thereafter, the entire surface of the etching base is exposed to radiation in order to solubilise the parts which were originally not irradiated through the mask. The etching base is then developed in an alkaline developer, during which the parts originally covered by the mask are removed. The remaining zones consist of the parts which were irradiated through the mask; they project in a relief-like manner from the substrate and represent a negative image of the original mask.

Patent DE-3544012-A1 (DE)
Title: Curved barrier element
Inventor: DENTZER GEORG
IPC: E01F13/08
Filed: 1985-12-13
Abstract: The invention relates to a curved barrier element which is intended to shut off vehicle-parking spaces or the like and has two legs which can be pivoted about aligned half-spindles, fastened on ground anchors, and can be supported in a virtually upright position by a support strut which can pivot in a similar manner. Possible means for locking in this position with the aid of padlocks have not proved successful since the padlocks either have to be taken away or have to be left on the ground together with the support strut which is lying flatly thereon. In this arrangement, there is the risk of a high degree of soiling and, in addition, weathering influences can result in operating problems. Unlocked support struts are, furthermore, also exposed to wilful destruction. According to the invention, these disadvantages are eliminated in that the legs are connected by a plate, on the rear side and underside of which there is arranged a closure mechanism which can be actuated through the plate and comes into engagement with the support strut, on the one hand, in the upright position and, on the other hand, in the position where it is parallel to the ground, metal closure sheets and/or closure openings being provided on the support strut, at two spaced-apart points, for this purpose.
