Abstract: ABSTRACT OF THE DISCLOSURE         An infrared-type intrusion detector for monitoring the presence of a person is disclosed.  The detector has a plurality of concave reflector segments for defining separate fields of view.  Infrared radiation emanating from the person in any of the fields of view is collected and focused upon a single sensing element to produce a cautionary signal representative of such detection.  Plane mirror means are introduced in an optical reflection system of the detector to reflect the radiation from the reflector segments upon the sensing element, such as to reduce the spacing or dimen-sion required for the optical system along the optical axis of the sensing element, whereby the detector is allowed to be made compact in size.  Further, the optical system of the detector includes means for selectively interrupting one or more paths between the respective reflector segments and the sensing element, such that the detector can receive the infrared radiation only from the selected or desired fields of view and ignore it from the undesired fields de-pending upon certain operating conditions, enhancing detec-tion reliability.

Abstract: ABSTRACT OF THE DISCLOSURE     A field subassembly is assembled by positioning two coil supports adjacent respective core end faces of a ferromagnetic core.  The core-engaging surfaces of the coil supports and the core end faces have respective surfaces which are uninterrupted by projections.  During the assembly of the field, fasteners are pushed into the respective coil supports and the core such that the fasteners engage mounting holes in the coil support with a press-fit.  After the field is wound, a brush holder subassembly is also pressed onto the fasteners and the resultant core subassembly is connected to a field housing by driving the fasteners in a conventional fashion. In the preferred embodiment, the fasteners provide a three-point contact with mounting holes formed in the coil supports and the brush holder subassembly.  This enables the fasteners to maintain the coil supports and the brush holder subassembly in alignment with the core while shearing a minimum of material from the coil supports and brush holder subassembly when the fasteners are pushed into their respective mounting holes.  Then, the same fasteners remain with the subassembly to connect the field subassembly to the field housing.

Abstract: Abstract A manual backup system (10) for a fuel control incorporating a metering valve (108) controlled by an electronic computer has a power piston (34) and a loading piston (60) in confronting relationship adapted to engage each other upon power being with-drawn from a solenoid operated valve (72).  The loading piston acts to maintain an arm (28) in engagement with the power piston so that it follows the power piston's movements as controlled by a servo valve (48), incorporating a fuel flow to compressor dis-charge pressure schedule (54) operated by a PLA lever (74).  The position of the arm represents a requested fuel flow to discharge pressure ratio.  The arm is mechanically connected to the meterin valve through a multiplier linkage (96) which is also connected to a compressor discharge pressure transducer (98) so that the meterin valve is positioned in accordance with the requested fuel flow to discharge pressure ratio as multiplied by the sensed compressor discharge pressure.  Fuel flow is metered on the basis of an adjustable manual fuel flow to compressor discharge pressure schedule with the PLA lever operating in its normal quadrant.         The PLA lever is not susceptible to being back driven during changeover or manual operation.

Abstract: ABSTRACT      A machine for packaging objects such as rolls of paper comprises a direction changing loading wheel to feed objects and groups of objects into closely grouped orientation in the wrapping machine for high speed passage through the machine in a continuous motion generally in a single direction and substan-tially at a single speed.  A wrapper supply mechanism feeds sheets of wrapping material to lie between conveying belts above the article to be wrapped with the leading edge of the wrapper substantially ahead of the article or group of articles to be wrapped.  A pair of vacuum wheels alongside the path of the ar-ticle on axes skewed slightly outwardly from the article path pull the wrapper down in front of the article and allow it to pass underneath as the article passes so that the wrapper becomes wrapped around the top, front and bottom of the articles. Specialized belts and rollers below the periphery of the vacuum wheels assist in smooth transfer of the wrapper without permitting wrinkles at that very high speed.  The articles are then transferred from the belt conveyor to bars above and below the article, with chain driven paddles to propel the articles and to wrap the upper and lower portions of the tail of the wrapper about the rear of the articles while at the same time differences in the coefficient of fric-tion between the upper and lower bars snug the wrapper about the article and close and spaces between articles in a group.  The ends of the wrapper are folded in and the ends and rear seam are sealed to continuously produce wrapped product groups as the groups move in a linear path, in part by a novel fold tucker.

Abstract: COMMUNICATION SYSTEM FOR VIDEOCONFERENCING    ABSTRACT            A system for videoconferencing saves travel time and money. To enable participants to see each other continually and simultaneously, and to show documents and objects, equipment is needed, the costs of which vary with the number of locations to be interconnected, and with measures taken for reducing the needed transmission capacity and the outfit of each terminal. As in known videoconference systems, such as studio, or working place systems, the video and audio signals are switched and/or mixed in the inventive system.  The necessary equipment, however, is no longer needed at the respective locations, if a central station for videoconferencing is provided which includes this equipment only in a volume actually necessary for the conference.  Each of the connected particpant locations only comprises terminal units, the same which are needed for a picture-telephone  system  In addition, both the video and the audio reception can individually be controlled from each location.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for grinding woodchips into pulp provides an internal grinding surface of circular section defining a cavity in which a rotor rotates.          The rotor has a pocket extending to the grinding surface from an inlet spaced inwardly from the grinding surface, and the rotation of the rotor gives rise to centrifugal force urging woodchips against the surface, the woodchips entering at the inlet.  The woodchips form a compact plug of material filling the pocket adjacent the surface, and the woodchips are ground to pulp and then removed from the surface to a discharge.          A pressure differential is placed across the plug of material in the sense to urge the woodchips in the plug more strongly against the grinding surface, so that the woodchips can press with a satisfactory grinding force against the surface without requiring an excessive rotational speed.

The intermediate section includes a frusto-conical wall in two parts 16 and 18, each of 180° angular extent.  The ram 24 operates a wedge 22 longitudinally to move the first part 16 outwardly or inwardly transversely of the body.     The parts 16, 18 are slidably trapped to the wedge by slide components projecting into grooves.  The tool is pulled by the tow cable into the main with the part 16 retracted.  Then the part 16 is moved outwardly to burst and enlarge the main, allowing the tool to advance further after retraction of the part 16.  The parts 16, 18 each have an external longitudinal rib 68, 70.  The part 16 has longitudinal marginal extensions overlapping the longitudinal margins of the part 18.
