Abstract: ABSTRACT OF THE INVENTION               Fluid Injectors A fluid injector 1 for an oil fuel burner suitable for firing the fuel of a boiler includes an injection device 2 which can be inserted into the wall of the boiler to an operating position at which oil discharge can be safely permitted and withdrawn from that operating position for inspection and servicing.  A flow control valve 3 of the fluid injector 1 is adapted for connection to an oil fuel and delivery circuit and is mounted in a fixed position relative to the boiler wall.  The fluid injector 1 also includes a fluid coupling device 11 between the injection device 2 and the flow control valve 3.  The fluid coupling device includes male and female terminals 19 and 20, respectively, which are fast with the injection device 2 And the flow control valve 3, respectively.  The male and female terminals 19 and 20 are disconnected as the injection device 2 is withdrawn whilst the change-over valve remains mounted to the boiler wall and connected to the oil fuel and return circuit, at which time the female terminal 20 isolates that circuit from the withdrawn injection device 2 and seals flow from the circuit within itself.  When the injection device 2 is inserted to its operating position, the male terminal 19 interconnects with the female terminal 20 to communicate the oil fuel and delivery circuit with the injection device 2 through the flow control valve 3.  The flow control valve 3 may provide a direct flow path through itself when the injection device 2 is withdrawn to allow oil to circulate continuously in the oil fuel and delivery circuit at that time.

Abstract: RCA 76,945 ABSTRACT OF THE DISCLOSURE A ferroresonant power supply having a relatively temperature stable output voltage includes a saturating magnetic element having a magnetizable core and a winding located thereon.  A magnetizing current is developed in the winding by a high frequency source of alternating input voltage for generating an alternating magnetic flux in the magnetizable core that links the winding so as to develop an alternating polarity output voltage.  A capacitor develops a circulating current that generates a magnetic flux in a core section associated with the winding that aids in magnetically saturating the core section to provide regulation of the alternating polarity output voltage by means of ferroresonant action.  In order to temperature stabilize the output voltage, the magnetically saturating core  section of the magnetic element is formed of a ferrospinel comprising a lithium ferrite or a substituted lithium ferrite.  The lithium cation containing ferrospinels have desirable magnetic properties of a relatively small change in saturation flux density with temperature and, when properly manufactured, a low coercivity which results in a relatively small temperature rise above ambient temperature in the saturating element.  When the ferro-resonant power supply is used to generate an ultor voltage for the picture tube of a television receiver, the regulated alternating polarity output voltage may be stepped up and rectified to provide a regulated DC ultor voltage that is relatively temperature stable.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and an apparatus is disclosed for forming a multi-layered container of compressible sheet layers, such as corrugated board.  The containers are formed in a single operation and avoids the known techniques of folding the layers before laminating in multistep methods.  Furthermore, the container may be folded without the layers separating.          The method of forming a multi-layered container having a plurality of flat sides with corners between adjacent sides comprises winding compressible sheet layers on a forming mandrel.  In the process, one edge of a layer is attached adjacent to a corner of a mandrel, a shoe plate applies pressure to the layer against the mandrel as it rotates to maintain a substantially constant pressure and tension on the layer.  An additional momentary force is applied to the shoe plate as each corner of the mandrel passes over the shoe plate such that the layer at each corner is compressed.

The releasable mechanism is made up of a first forwardly facing hook for receiving the front support pin of the bucket and a downwardly facing notch which receives the rear pin on the bucket, and a second hook attached to the bucket support that swings under the rear pin of the bucket when it is supported in the downwardly facing slot notch.                         GENERAL STATEMENT OF INVENTION This invention relates to earth working apparatus and more particularly to the type of earth working apparatus commonly known as backhoes. Backhoes which are made according to present inventions have disadvantages in that the backhoe buckets are generally not readily releasable and detached from the dipper sticks. Applicant has provided a new combination with a backhoe of a tiltable bucket which has means to swing the bucket about an axis passing through the bucket and tractor so that a level bottomed ditch can be dug on a hillside, in combination with a releasable mechanism which can quickly release the bucket from the dipper stick. It has been discovered that by providing a means for quickly releasing and attaching the bucket on the end of a dipper stick the bucket can be readily transported for repair or to a new location or for compact storage or can be exchanged for another bucket.                              REFERENCE TO PRIOR ART This invention is an improvement on U. S. Patent No. 3,231,116 which shows a backhoe with tiltable bucket which is not quickly removable from the dipper stick, and U. S. Patent No. 3,794,195 which shows a front end loader bucket which is quickly removable from the dipper stick. However, the mechanism for removing the bucket from the '195 patent is not suitable for use on a backhoe.

Abstract: A HIGH SPEED OPTICAL SWITCH AND TIME              DIVISION OPTICAL DEMULTIPLEXER            Abstract The present invention relates to a high speed optical switch and the use of such switches to form a time division demultiplexer.  The optical switch comprises a length of linear material including an outer surface on a portion of which is formed a layer of nonlinear material to form a nonlinear interface at the boundary of the two materials.  An input data light beam is propagated in the linear material with a predetermined intensity and angle of incidence on the nonlinear interface to, by itself, cause total reflection of the input beam.  A control light beam is also selectively energized and directed at the nonlinear interface with an intensity and angle of incidence to cause a portion of the input data beam to be formed into a self-focused channel or beam propagating in the nonlinear material.  The self-focused beam can then be detected at an edge of the nonlinear material.

Abstract: Abstract Diffuser Case For A Gas Turbine Engine The strut supporting the diffuser to the engine outer case wall which also supports the shaft bearing of a turbine engine is conically shaped having its base located downstream with respect to the flow of the engine working medium and is judiciously angled so that the line of action for the bearing load is aligned to coincide with this angle, pass through the strut and intersect the centerline of the engine and the midpoint of the bearing. This enhances the stiffness of the support, reducing the weight necessary to support the same load. The diffuser case and support from the diffuser to the bearing is offset from the strut to minimize direct radial thermal incompatibility and the diffuser is spaced from the outer engine case wall reducing thermal stresses.
