Patent MX-PA99010353-A (MX)
Title: Arc fault detector apparatus.
Inventor: JOHNSON ELTON C
IPC: H02H1/00
Filed: 1999-11-11
Abstract: A sputtering arc fault detector (10) for a system having an electrical conductor (14) carrying current to a load. The sputtering arc fault detector includes a current monitor (64) coupled to the conductor for generating a variable signal responsive to behavior of the current in the conductor. A level detector (58) is coupled to the monitor and generates a first pulse when the variable signal exceeds a first level. A step detector (62) is coupled to the monitor and is responsive to rapid step increases of the variable signal. The step detector generates a second pulse when the variable signal exceeds a second level. An arc verifier (48), which is coupled to the level detector and the step detector, combines the first and second pulses, and generates a fault signal when the combined pulses exceed a third level.

Abstract: 958,249. Semi-conductor circuits. TEXAS INSTRUMENTS Inc. May 6, 1960 [May 6, 1959], No. 46090/63. Divided out of 958,242. Heading H1K. The subject-matter of the Specification is included in Specification 958,242. The claims relate to a circuit comprising a monocrystalline semi-conductor wafer containing a plurality of first regions, each of which overlies a second region with which it forms a PN-junction extending to a major wafer face and there defining an enclosed area. The wafer includes an elongated portion providing a current path parallel to said face with one end connected to a bias potential and the other ohmically connected to said second regions. Input connections are provided on the first regions. Specifications 945,734, 945,737, 958,244, 958,245, 958,246, 958,247 and 958,248 also are referred to.
Patent MY-8400287-A (MY)
Title: Door closer
Inventor: CHADDOCK DENNIS HILLIAR
IPC: E05F3/12
Filed: 1984-12-30
Abstract: A door closer includes a tension member comprising spaced shafts acted by springs and connected to articulated chains which are coupled to an anchor plate secured to the door frame. Movement of the shafts is under the control of a uni-directionally operative fluid-filled damper having a piston carried by a piston rod which is connected to a cross head slidably mounted on the shafts and held against abutment washers by the springs. The damper serves to regulate the rate of movement of a door in the direction of closure without restricting significantly the rate of movement in the direction of opening. A fluid by-pass is provided in the damper by a rebate formed in the cylinder so that as the piston approaches the end of the cylinder over the final part of the closure movement the restraint imposed by the damper is relieved. The point in the closure movement at which the fluid by-pass becomes operative can be varied while the closer is installed so as to provide compensation for variations in the installation of the closer and variations of the gap between the door and its frame. In one embodiment this is achieved by securing the chains to an adjustment plate which is movable towards and away from the anchor plate. In another embodiment the piston rod is adjustable secured to the cross head, which in this case is in the form of a stirrup with a cross member on which the piston rod is carried presented towards and accessible from the outer end of the housing so as to enable the piston rod to be adjusted.

Abstract: 1,073,203. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. Match 15,1966 [March 25, 1965], No. 11188/66. Heading H4R. Channel. vocoder in which each spectrum analysis channel includes a band-pass filter, a rectifier, and a low-pass filter, or integrator circuit; has a voiced-unvoiced detector the output from which is used to lower the cut-off frequency of the low-pass filter, or increase the integration time of the integrator circuit, when unvoiced sounds are detected; in order to reduce noise in the channels. The voiced-unvoiced detector may cause switching between two alternative filters provided for each channel, Fig. 2 (not shown), or it may modify the filtercircuit, e.g. by operation of switch Si. in the filter of Fig. 3. A typical integrator circuit which might be used in each spectrum analysis channel is shown in Fig. 5 in which the spectrum channel signal is applied to band causes capacitor C to be discharged by an amount proportional to the current applied through R 1'  Periodically a signal is applied to line a to cause TR 2  to conduct to charge C up to the supply potential. The charging current, which will depend on the total discharge of C since the last charging pulse, flowing through R3 will produce an output pulse on Ki<SP>1</SP> the amplitude of which is proportional to the integral of the spectrum channel signal over a time equal to the period of the pulse signal applied to line a. The voiced-unvoiced discriminator output is employed to increase the period between the pulses applied to line b during unvoiced sounds.

IPC: E06B7/23
Filed: 1972-11-10
Abstract: The opening in a window casing assembled from four lengths of extruded aluminium channel is provided with two sliding sashes having frames of extruded aluminum. The lower horizontal frame member of one sash rides on wheels whose rim matches the semicylindrical top face of a guide rail on the lower horizontal casing member so that the sash may be pivoted about the axis of curvature of the guide rail face. Tilting of the sash is limited by brackets, each bracket including a slide guided along the upper casing member and a link pivotally connecting the slide to the top of the sash.

Title: Suction dredger spoil quality monitoring system - detects particle coarseness from noise made in travelling through pipe
IPC: G01H1/00
Filed: 1974-08-27
Abstract: The degree of coarseness of the particles passing through the dredger pipe is monitored by an acoustic device, typically a microphone (2) picking up the noise made by them as they travel along the pipe (6). The signals emitted by the microphone are transformed into signals fed to an audiometer. The sound generated can be picked up at a bend in the pipe, and the audiometer can be arranged to measure the sound where this exceeds the preset level for a particular particle size. The signals picked up and transformed can be audigraphically represented, and the output signal from the microphone can be coupled to the signals from the devices measuring the speed in the pipe and the concentration of material.

Patent NL-7907353-A (NL)
IPC: G10L15/00
Filed: 1979-10-03
Abstract: Ideographic character selection and recording is accomplished by apparatus that encodes outputs of individually operable devices each corresponding to an unique character identifier component, for example phonetics. That encoding is used to address a data store containing whole characters or keys thereto organised in sets according to particular ones, preferably combinations, of the character identifier components. A limit of less than 7 device operations is envisaged for data store address completion. A visual display unit will then show all contents of a selected set for selection of the particular one character being entered by said devices. Data identifying that character is then added to an encoded multi- character message, and may simply be printed out locally or transmitted to some more sophisticated utilisation means, such as printing machinery or transmission facilities. <IMAGE>

Title: Mortise lock for apartment block front door - can be opened and closed using key or by remote electrical control
IPC: E05B47/00
Filed: 1985-10-07
Abstract: Set into the door is a multi-lever mortise lock. The lock may be operated directly by turning a key (14) in the keyhole (13) and lifting the levers (3) over the stop (8) against the leaf springs (4). Once the levers are released, the key moves the bolt (6) in or out of the socket in the door jamb.
