Patent IT-1242237-B (IT)
Title: Device for measuring distances
Inventor: MELTESE UGO
IPC: G01C/
Filed: 1990-11-14
Granted: 1994-03-03
Abstract: The invention relates to a device for measuring distances, in particular of the contactless type. In order to avoid errors and inaccuracies in the measurement due to the shape of the surfaces S of objects being measured, their chromatic features and the variations in response of the device due to thermal effects, the invention envisages a measuring device comprising a device 1 emitting a beam I of electromagnetic rays suitably modulated and directed against the surface S being measured and a receiver 4 for detecting the reflected beam R. The measurement of the distance is determined in a suitable processing circuit by the phase difference between the modulation signal of the incident beam I and the reception signal corresponding to the reflected beam R. <IMAGE>

Title: Snow-making process and apparatus
Inventor: DURYEA GEORGE R
IPC: A63C/
Filed: 1989-08-25
Granted: 1991-12-21
Abstract: The process and apparatus provides a stream of pressurised air and pressurised water, and combines the air stream and the water stream to cool the water and provide a first stream of a mixture of the air and water. A portion of the air is aspirated in a counter-flow direction from air into the first stream and mixing with it to form a second stream of a mixture of air and water. The second stream is coaxial with the first stream. The second stream is dispersed into freezing temperature atmosphere to freeze the water in the second stream and produce snow. A central stream of water of pressure of at least 300 psig is combined with air of pressure no more than about 30 psig coaxially combined and creating the first mixture. Ice crystals are utilised as a nucleating agent to promote the freezing of water in the second stream.

Title: Liquids steriliser
Inventor: MAZZOTTI ERMANNO
IPC: A61L/
Filed: 1982-11-05
Granted: 1988-02-24
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Title: Rotary pile-driving accessory mechanism
Inventor: HOCHSTRASSER JURGEN
IPC: E02D/
Filed: 1983-07-20
Granted: 1988-12-06
Abstract: The rotary mechanism works in alternate directions and aids driving or extraction of tubes, piles etc. It has a bearing ring secured to the tube etc. and a rocker lever turning on it, with symmetrical arms having inertia weights on the ends. Pairs of stops on the ring and on an inside flange of the lever transmit the energy, while rams are coupled between the ring and lever. Each energy-transfer member (18) is of incompressible elastic material, fitting in recesses (20) in one or both of the stops (15,16) in a pair. They allow its deformation within the elastic limit, particularly at right angles to the direction of impact. Direct contact between the stops is thus prevented.

Title: Thermoplastics pieces injection moulding
Inventor: BUZZI FERRUCCIO
Filed: 1984-05-08
Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.
Patent LT-6220-B (LT)
Title: A food waste strainer
Inventor: RONIS ARTŪRAS
IPC: A47J47/00
Filed: 2014-01-17
Abstract: A food waste strainer for domestic industry, created to solve the dishwashing problem when dishes with much waste, such as coffee or tea cups, have to be emptied prior to washing, to prevent grounds from blocking the drain. In particular, this is a problem in private or old houses with different local drainage piping defects. Grounds make accumulate in such areas. At present, this problem is solved by discharging solids and other waste into a separate container, which is often further away from the sink and there’s not match the kitchen interior. Such solution is inconvenient and takes more time. The solution offered by the patent is a device separating food waste from water. Waste remains in the device and will accumulate there until the net gets full, and will be then disposed to the bin without free water. Waste is removed by inverting and shaking the net. The filtrate will separate from the waste and run through the sink; it will not have an adverse effect on the sink, or the drain system because it will not have solid particles, or their quantity will be quite low.

Patent MX-170065-B (MX)
Inventor: PIES PAUL B
IPC: F16H3/76
Filed: 1989-08-15
Abstract: A technique for modifying an input rotation in continuously variable increments to produce a controlled rotational output is disclosed herein. This technique combines epicyclic motion of a series of planetary shafts in a parallel fashion in order to produce continuous, controlled, intermediate output in the same direction and at the same speed or a greater speed than the input rotation. This intermediate output is then modified to produce a continuous, controlled, final rotational output only when the intermediate output is greater in speed than the input. The final output can be in the same direction as the rotational input and at a speed which is proportionate to the excess speed of intermediate output.
