Abstract: 1                 PHF 78.548 ABSTRACT:           In a filter in which, in order to obtain the desired filter characteristic, a weighted sum of differ-ent signals is formed, it is proposed in accordance with the invention that for the formation of said sum devices are employed which are constituted by capacitor circuits, which during a first time interval are each charged by said signals, and by a connection circuit for the form-ation, during a second time interval, of the equivalent of a single capacitor across whose plates the weighted-sum signal appears.  The invention is used for the fil-tration of sampled analog signals.

Abstract: Abstract of the Disclosure Disclosed is a portable pelorus for use on a vessel such as a ship.  A pelorus is a sighting device used to obtain the azomath bearings of objects for the purpose of navigation.  Existing pelori are either mounted on a pedestal in the bridge or retracted from the bridge deckhead and consequently available reference targets are frequently obscured by "wooding" around the bridge windows.  Two embodiments of portable pelori are disclosed, an optical version and an electromagnetic version. In the optical version, a rotating beam of light is reflected from a reflector mounted at a known angle to the ship's axis and is detected by a photodiode when the beam is perpendicular to the reflector to provide a reference bearing.  The bearing of a sighted object is provided by the output of a shaft-angle encoder to provide the relative bearing of the sighted object.  A microprocessor can utilize the relative bearing and the ship's bearing to derive the object's true bearing.          The electromagnetic version determines the ship's heading by using two orthogonally mounted coils for sensing the oscillating magnetic field produced by at least one electrical conductor mounted at a known angle to the axis of the ship  The voltages produced by the coils are used to activate servo device to maintain one of the coils parallel to the conductor.  A shaft angle encoder again provides the relative bearing of a sighted object for the microprocessor to derive the true bearing of the object.

Abstract: ABSTRACT      A cross flow rotary mower has a rotor with horizontal outer cutting edges and upwardly extending blower vanes. A conduit having upper, lower and side walls cooperates with the rotor to form a cross flow blower.  The rear semi-circle of travel of the rotor is within the conduit. The inlet opens forwardly and has a lateral extent pre-ferably as great as the diameter of the tip circle of the rotor.  The cutting edges extend forward of the lower wall, and preferably the lower wall extends to the cutting edges. An extension of the upper wall extends forwardly beyond the tip circle with front and side skirt portions.  Means for producing and strengthening vortex air flow are described, and also inlet air flow control vanes.  A number of rotors and conduit arrangements with advan-tageous features are described.  These include dual blower vane arrangements.  Force-controlled retractable blades mounted on a blade carrier are described which avoid undue cutting forces and also enable the use of thin blades requiring no sharpening.

Abstract: APPARATUS FOR COOLING HOT GASES                           ABSTRACT    There is provided an efficient, economical apparatus for cooling hot gases which includes three generally cylin-drical, tubular members arranged in an upstanding U-shaped configuration.  The hot gases are introduced downwardly into the first leg or member of the configuration where a plurality of water nozzles provide a water boundary cir-cumscribing the interior of the first leg to prevent ther-mal fatigue thereof.  A water nozzle in the first member acting as a jet pump entrains the hot gases and directs them into the transverse leg or member of the configura-tion for rapid, turbulent cooling therein.  Packed beds are provided in the second upstanding leg or member of the configuration to permit scrubbing of the cooled gases prior to exit.  Cooling the gases in such a manner permits the entire configuration to be constructed of steel plate without any special insulation.

Abstract: Abstract Multi-layered optical data records and playback apparatus are des-cribed in which a plurality of optical data layers are provided on at least one side of a record substrate and the playback apparatus scans data tracks on such layers with a light beam to produce an electrical readout signal corresponding to the data in the scanned tracks.  The playback apparatus includes selection means for selectively playing back data tracks on different ones of the data layers.  The data track may be formed by lines of data spots of binary coded digital information or such spots may be frequency modulated or pulse length modulated analog information which are photographically re-corded at extremely high data density so that they may be used to record audio or video signals including television signals.  While the optical data records may be light transparent, they are preferably light reflective so that the playback light source and associated focusing and scanning means may be sup-ported on the same side of the record as the light detector to provide a more compact playback apparatus.  This also enables at least some of the same optical elements to be used for transmitting the reflected light beam to the detector that are used for transmitting the playback light beam from the light source to the record.  Selection of one data track for playback may be accom-plished by changing the focus of the light beam from one data layer to another, or by making the data tracks of optically different materials, such as using different color dyes or different photoluminescent materials, and selectively positioning corresponding color filters in front of the light detectors.

Abstract: TIMING APPARATUS FOR DELAYING OPENING OF DOORS         Abstract of the Disclosure Opening of a door, such as an emergency exit door, is delayed by encumbering a security device, such as for example a latch bolt, with the task of throttling a hydraulic fluid through a circuit, which circuit includes a normally open valve held closed by a solenoid. When the solenoid is de-energized, the circuit is opened allowing the security device to move so that the door can be opened. The solenoid is controlled by an electrical timing circuit which delays de-energization of the solenoid. The timing circuit is started by a switch mounted to be operated by movement of the latch bolt. Preferably in a situation where there are a plurality of doors, doors proximate to one another are delayed by the same electronic timing circuit. In a preferred embodiment, the electonic timing circuit is set to de-energize the solenoid at a time subsequent to the delay resulting from throttling the fluid.
