Abstract: ANGLE OF ATTACK BASED PITCH GENERATOR AND HEAD UP DISPLAY                         Abstract A circuit for computing a signal representing the pitch attitude of an aircraft utilizes angle of attack based information and the output of a gyroscope to produce a calculated pitch signal which has a long term component dependent upon the angle of attack based information and a short term component dependent upon the gyroscope output signal.  The calculated pitch signal may be used to pitch stabilize a head up display in the aircraft and in this event is modified with a correction signal derived from the pitch signal and the output of a head up display mounted accelerometer.  Alternatively, the pitch signal may be combined with a signal representing the difference between the output of the display mounted accelerometer and the output of an angle of attack vane mounted accelerometer to provide a pitch stabilization signal which is free of turn and shear errors.

Abstract: ABSTRACT OF THE DISCLOSURE          An oil burner for installation in heating or steam-raising boilers has, downstream of an oil atomization device, a plate having a single opening or a plurality of openings arranged in a ring coaxially of the oil atomizing device, the opening or openings being the only passageway for com-bustion air.  A mixing tube is arranged coaxially at a dis-tance downstream of the plate.  The mixing tube has a dia-meter greater than the diameter of the single opening or of a circle which encloses the plurality of openings in the plate.  A flame tube positioned coaxially around the mixing tube has a length such that the flow of combustion gases downstream of the mixing tube is applied against the internal wall of the flame tube.  To enable the burner alter-natively to be used for burning gaseous fuel at will, an annular chamber for the supply of a gaseous fuel and having gas outlet openings in the region of the plate opening or openings is also provided downstream of and close to the plate.  By the use of substantially similar component parts it is possible to manufacture a burner solely for gaseous fuel comprising the plate, a passageway for the combustion air and an annular chamber downstream of and close to the plate for the supply of the gaseous fuel and having gas outlet openings in the vicinity of the plate opening or openings.

Abstract: Docket M-295 PRINTING APPARATUS            Abstract of the Disclosure There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an  operating lever.    The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker.  The travel of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted.  The cam means is part of a lost-motion connection which couples the slide to the inker.  As the operating lever is cammed in one direction to move the feed finger forward,  the inker is moved into and out of inking cooperation with the print head assembly.  Because of the lost-motion,connection adjustment of the pivot does not affect the length of travel of the inker.  When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the apparatus with the web of record members.  The print head assembly includes a pair of print heads, each print head having at least one series of rotatably mounted drive wheels and a support.  A plurality of printing bands having different printing elements are trained  about the support and respective drive wheels.  Each support of each print head is adjustable by exerting forces at opposite ends of the support so that all the printing elements at the support are disposed in a common plane parallel to the platen.  The Docket M-295 print heads are rigidly interconnected by plates.  Set screws threadably received by one of the plates are accessible from about the print head and act on adjusting plates which exert forces at opposite ends of the respective supports.

Abstract: Abstract of the Disclosure A reciprocating dialyzer is described for use as an artificial kidney or other extracoporeal mass transfer device.  A dialyzer unit includes a membrane package having an aligned pair of thin semi-permeable membranes forming a chamber between the interior faces to receive fluid (such as blood) to be treated, and spacing elements in dialysate chambers at the exterior faces of the membranes which contact the membranes and limit their expansion, while allowing chemical transfer to the dialysate slurry.  A plurality of such treatment units received between spaced plates comprises a dia-lyzer.  Blood flow into and out of the membrane packages is through a central conduit, with free slurry being introduced and withdrawn from the dialysate chamber at the periphery of each unit.  The spacing elements are flexible and of plastic with molded, porous or mesh material modified to provide central and rim seals as well as membrane engaging faces designed to limit membrane displacement and cause formation of a thin blood column while not unduly masking the membrane surfaces and allowing slurry flow at all times includ-ing when the blood chamber is filled with blood. Certain spacing elements also allow emptying of blood from the dialyzer without need for positive pressure on the fluid outside the dialyzer.

Abstract: 48,946 ABSTRACT OF THE DISCLOSURE Vacuum circuit interrupter apparatus is taught in which a movable stem is interconnected with one of the separable main contacts  thereof.  Flat  planar  flexible conductors  connected  in  parallel  circuit  relationship between the stem and a fixed terminal  for the  circuit interrupter  system  are  utilized.   Planar  members  are spaced  from  each  other  for  enhanced  heat  dissipation characteristics.   Furthermore,  the planar  members  are generally  self-supporting  except  for  the  flexibility associated with a particular shape,  consequently are not likely to randomly touch other apparatus in a switchgear cabinet.  Nevertheless, the amount of conductor represent-ed by the parallel planar members is sufficient to conduct electrical current when the circuit interrupter is closed.

Abstract: ABSTRACT:               A fault location arrangement for a digital optical transmission system employing repeaters has at each repeater an opto-electrical converter and an elec-tro-optical converter.  The output of the opto-electrical converter is fed via an AGC amplifier and a regenerator to a modulator which comprises a two pole two way switch, a single pole two way switch and two current sources. The two pole switch is controlled by the regenerated data while the single pole switch is controlled by a fault location signal.  The arrangement is such that fault *        information is transmitted by amplitude modulation of the digital signal but that the average power applied to the electro-optical converter remains constant.  Hence the amplitude modulation does not cause a varying dissipation in the converter and hence reduces the possibility of variation of the wavelength emitted by the converter.
