Patent DE-3121491-A1 (DE)
Title: Security paper having authenticity features in the form of luminescent substances, and process for authenticity testing of the security paper and device for carrying out the testing process
Inventor: KAULE WITTICH DIPL PHYS DR
IPC: G06K19/14
Filed: 1981-05-29
Abstract: Security paper having incorporated or imprinted luminescent authenticity marks which absorb in the visible region of the optical spectrum or have a transparent region in the infrared in which the luminophore also emits. As a result of the absorption in the visible region, undesired parasitic emissions which would make the luminophores visually discernible on appropriate excitation are suppressed. The emission in the infrared is used to detect the authenticity of the document. Suitable luminophores are rare earth metal luminophores in suitable host lattices, in particular in ferrite lattices or garnet lattices which contain transition metal ions as absorbing elements.

Title: Process for improving the corrosion resistance of stainless knife blades
Inventor: WELZ STEFAN
IPC: C21D6/00
Filed: 1981-07-07
Abstract: A process is indicated for substantially improving the corrosion resistance of table knife blades of the forged type. As is known, an intensive surface treatment, whether it be polishing or grinding in the case of previously hardened blades, produces structural changes which lead to an increased corrosion susceptibility. "Wave bevel grinding" especially leads to considerable heating with significant structural changes and stresses. This fault does not arise when the heat treatment is applied at the end of the mechanical surface treatment operations. It is a precondition in this case that this heat treatment is carried out in a clean protective gas atmosphere, where to improve the retention of sharpness an opportunity for quenching should be available, but this is not compulsory and depends on the carbon content of the steel in question and on the quenching rate. The optimal corrosion resistance of the steel in question is achieved by this novel process.

Title: Method for detecting movements in video camera images
Inventor: BEIS UWE DIPL ING
IPC: G08B13/194
Filed: 1982-04-17
Abstract: This is a method for detecting movements in video camera images by evaluating the signal supplied by a video camera from a scene to be monitored, in an electronic motion detector with simultaneous reproduction on the screen of a monitor. In this method, the mean brightness fluctuations of part areas or areas of the camera image, generated separately from one another, are processed in the motion detector in such a manner that it can be detected and distinguished whether these fluctuations are an excitation in the individual surveillance fields or fluctuations in the brightness in the signal of the video camera. This is done by obtaining the information whether these are fluctuations in the brightness in the signal of the video camera from a relatively large number of fields, a distinction between excitations of individual and several fields being possible due to special processing of the individual signals obtained. Transgression of a set threshold value leads to an alarm being triggered.

Title: Cooled racket handle a - tennis racket b - table tennis bat c - badminton racket
IPC: A63B60/18
Filed: 1983-03-23
Abstract: The fact taken as the basis is that until now there has not been a cooled tennis racket, table-tennis bat or badminton racket. The state of the art is currently that the handles of the individual rackets or bats are indeed wrapped in various materials. However, practice shows that this cannot prevent these materials becoming moistened to a greater or lesser extent during use of the rackets or bats, so in turn there is no firm and sustainable gripping or holding of a racket or bat. Players are always complaining that the handle of the racket or bat is not optimum. The present patent accomplishes, however, that   a - the handle of the racket or bat is cooled specifically to the body heat of the person, b - subsequently the handle of the racket or bat rests firmly in the player's hand.   The cooling can be adjusted specifically to the respective body heat of the player by means of a corresponding bore. The winding-insulation arranged on the handle can also be used, by deciding on a material which is pleasant and to the liking of the player. This handle cooling presented here has the effect of preventing heavy perspiring of the palm of the hand and ensuring that a firm gripping of the handle, conducive to play, is always ensured in every situation.

Title: Picture device for video telephony
Inventor: ORLOB WOLFGANG
IPC: H04N7/14
Filed: 1983-04-08
Abstract: In a video telephone having a camera (1) which can be rotated in height and a deflection mirror (4), which can be pushed in front of the lens (2) to cover a document support area if needed, the mirror inclination is adapted to the camera inclination, which is set for recording a person, in such a manner that when a document is recorded, the same image section of the relevant support area is always covered. The inclination of the mirror is adapted via a compensating lever (12), supported on the camera and a fixed carrier (7) of the device, when the camera inclination is adjusted manually. According to the invention, a guide pin (13) is guided for this purpose at the compensating lever (12) in each slide position of the mirror in the same manner in a longitudinal groove (14) of a guide prism (11) mounted on the rear of the mirror. The mirror inclination is thus adapted without unevenly loading the force variation during the sliding of the mirror. <IMAGE>
