Title: Positioning of head assembly in miniature disc. cassette
Inventor: JANOSI MARCELL
IPC: G11B/
Filed: 1980-09-05
Granted: 1988-09-22
Abstract: The information is recorded on a miniature floppy disc in a cassette in the memory sectors of circular tracks. Fine adjustment to the head position is provided by detection of track marker frequencies on either side of the required track. The relative signal amplitude determine the head position. A combined read and write head located above the tracks on a mini floppy disc senses frequencies in adjacent marker tracks. The output is amplified and applied to two frequency selective circuits to select the two amplitude components. These are applied to a differential amplifier the output of which is applied to a second amplifier with a reference signal input. A control amplifier responds to the input signal to excite the windings of a precise positioning assembly for the heads.

Title: Manufacturing procedure, with the use of waste material from high resistance recyclable ceramic tiles, a mixture realized according to the procedure and the tiles produced.
Inventor: BARBIERI MAURO
IPC: C04B/
Filed: 1990-04-11
Granted: 1993-09-03
Abstract: This invention is the manufacturing procedure, with the use of waste material from high resistance recyclable ceramic tiles. This consists of a series of phases, the first of which prepares the mixture of waste glass, like Harlequin glass with the most prevalent components being potassium and sodium, and mud to be purified. the second phase collects the mixture in to vats with a built in mixer. The third phase is the introduction of the mixture into a measuring device. Then the fourth phase is mixing it with clay. The mixing is done inside the mixer for between 4 and 10 minutes. The resulting mixture then passes through a fifth phase extruding/drawing and cutting according to the shape to be attained, as well as, optionally, being sent to a sixth phase. This consists of drying over 2/8 hours at a temperature of less than or equal to 80 degrees C. This creates the hydrolysis and migration of potassium salt and sodium on the surface. The seventh phase is cooking the item in a temperature between 960 degrees C and 1000 degrees C for between 7 and 12 hours. This causes the glassification/sintering of the salts on the surface. The invention is the mixture for tiles according the aforementioned method, the mixture that is realized with a mixture with a percentage of waste material, called "Harlequin" glass above as well as with a percentage of clay and impure mud. All of which is mixed together with water to reach a humidity level of between 16 and 25%. The ceramic tiles produced in this manner end up having a high resistance rate and recyclable according to the procedure and the previous mixture, the tiles have a translucent layer of glassification/sintering from the cooking of the potassium salt and the sodium product during the hydrolysis. This occurred during the sixth and drying phase. The contact points with supports and similar items the external surface of the tile is smooth because of the absence of outcropping of the salts on the surface.

Filed: 2021-12-22
Abstract: The ankle-foot orthopaedic comprises a height-changing breathable calf support (4) adapts to the patient's calf and connects the accumulating flat spring section (7) at the ventral side. The frame continues to the lateral part of the ankle in the energy-accumulating frame curve (10) from the dorsal side. The frame (9) flares next to the sole (11) and then connects to it. The edge of the frame in this area is bent to the lateral side. The layers of the material are formed in such a way that allows flexibility of the frame in the anterior-posterior direction and eliminates its excess movement in the medial-lateral direction. The height-changing breathable calf support (4) is attached to the carbon frame through a height adjusters (8) and the angle adjuster (5), which allow changing the angle of this attachment in the dorsal-ventral directions and in the superior-inferior directions with respect to the footplate. The fastening elements of the buckles (1) are integrated into the calf support and form the entire construction.

Title: Broadband high-frequency radiation generating/amplifying device based on quantum semiconductor superlattice
Inventor: VALUŠIS GINTARAS
IPC: H01L29/00
Filed: 2021-10-27
Abstract: New principle and at the same time a new type of compact high frequency radiation source operating at room temperature that can be placed on a semiconductor chip is suggested. It is broadband and can operate in the both GHz and THz frequency bands (GHz-THz, from several GHz to THz; the cut-off frequency is determined by the super-lattice design, mainly by the width of its energy miniband). Operation of the device relies on principles of the quantum optoelectronics (Esaki-Tsu nonlinearity of the quantum super-lattice), and employ drift-relaxation modes to amplify high-frequency radiation, which propagates in a semiconductor superlattice along its axis at a speed approximately 1000 times slower than the speed of light in a material. It can be realized in semiconductor superlattice with non-ohmic injection contacts of an appropriate design.
