Title: Deflection yoke for TV CRT image adjustment - has two protective resistors between fixed contacts of variable resistor and feed driving coil terminal
Inventor: YABUSHITA HARUYASU
IPC: H04N9/28
Filed: 1990-08-13
Abstract: The deflections yoke has a field driving coil with two coils (11,12) conencted in series in a tuned diffraction yoke. The field driving coil is used to produce a magnetic field to rectify a convergence error in accordance with an electric current supply of the coils (11,12) through which the magnetic field can be fed into the cathode ray tube. A variable resistor (13) with a movable contact (14) and two fixed contacts is connected in parallel with the field driving coil via the two fixed contacts, and to a contact point between the two coils (11,12) via the movable contact (14), and serves to regulate the current between the coils (11,12) by moving the contact (14). Two protective resistors (17,18) are connected between respective fixed contacts of the variable resistor (13) and a corresponding terminal of the field driving coil. USE/ADVANTAGE - Prevents excessive current being produced in coil and overheating of resistor to allow fine tuning of current symmetry of coil.

Title: Procedure and device for thermal treatment of waste materials - comprises reactor combustion zone charged with waste, coke and lime, and gas produced passes through hot coke be also located in reactor
IPC: C10J3/08
Filed: 1990-09-27
Abstract: Waste material can be thermally treated in a reaction vessel. The reactor is loaded with the waste material (21), coke (22) and excess of a Ca- contg. material (24) such as lime or CaCO3. This mixt. is placed in a combustion and melting zone (V) which is separate from a coke bed (K) also located in the reactor, and is melted there. The gas (G) produced is passed through the coke bed at a high temperature in order to convert its CO2 content into CO. The melting zone is located above the coke bed, and the gas is passed through the coke bed and leaves the reactor at one side or at the top (16). Alternatively, the melting zone may surround the coke bed, the gas passing upwards, and the melted material downwards, through the coke bed. The melted material is collected at the floor of the reactor. Waste material, coke and Ca-rich material maybe loaded into the reactor in layers. An oxidn. substance (8) such as air or oxygen, and a fossil fuel (9), may be introduced into the melting zone and the coke bed from one side or from above. USE/ADVANTAGE - For thermal treatment of waste material such as household waste, industrial waste, filter dust, sewage sludge, packing material etc. The waste material is disposed of in a manner which is neutral to the environment, and in particular organic components are reliably destroyed and the products of the procedure can either be re-used or can be disposed of without problems.

Patent DE-4104096-A1 (DE)
Inventor: MIKOSHIBA NOBUO
IPC: H04B1/707
Filed: 1991-02-11
Abstract: The arrangement is applicable when a wide band information signal is subjected to a narrow band disturbing signal. A first embodiment in a spread spectrum receiver has a correlator 17 in the IF stage, the correlation output passing to a mixer 6, such as a double balanced mixer, having squaring characteristics whereby frequency components of a disturbing signal are shifted to the region of DC and a region at twice the frequency of the original disturbing signal. The mixer output passes to a band pass filter 8 to select only the frequency component of the correlation peak. A multi-stage arrangement with a plurality of mixers 6, 10, 14 and filters 8, 12, 16 may be used to remove a plurality of disturbing signals. In a second embodiment, a reference signal input to the correlator 17 is frequency modulated and is provided by a mixer (18) which multiplies the output of an FM modulating oscillator (19) by the output of a pseudo noise code generator (20). In a third embodiment, a notch filter (22) preceding the correlator blocks a centre part of the spectrum of the spread spectrum signal, which part is particularly weak against disturbance. The first embodiment may be combined with the second and/or third embodiment. (Figs 9 to 14). <IMAGE>

Title: Latch and/or cylinder actuated mortice lock - has main lock bolt actuated by gear train from lock cylinder
Inventor: BUCHSTALLER MICHAEL
IPC: E05C9/02
Filed: 1991-03-30
