Title: Self-propelled steerable walk behind mower linkage
Inventor: BRAUN STEPHEN A
IPC: B62D51/00
Filed: 1991-03-11
Abstract: ABSTRACT OF THE DISCLOSURE A mower control linkage having a double ended dead man control lever, left and right steering control levers, and a linkage interconnecting said levers with left and right transmission mechanisms.  The linkage has swingable left and right arm members that adjust the transmission mechanisms between braked, clutch disengaged and driven modes.  The arm members are connected to the dead man control lever via a lost motion coupling and are each linked with respective steering control levers.  As the dead man control lever is depressed, both arm members are placed in a driven mode, and either steering control lever can then be depressed to shift the respective arm member to its braked mode to execute a turn about that wheel.

Title: Phase shifter utilizing hybrid element
Inventor: UEDA HIROYUKI
IPC: H01P1/185
Filed: 1991-05-15
Abstract: ABSTRACT OF THE DISCLOSURE     A hybrid element  for phase shifting an input signal and providing  a  phase  shifted  output  signal  includes  conductive plates  which  are  capacitive  coupled  together.  The  hybrid element  includes  four  terminals:   an  input  terminal  for receiving  an  input  signal,  an  isolation  terminal  capacitive coupled with the input terminal and for providing an output signal,  a through terminal connected directly with the input terminal,  and a coupling terminal capacitive coupled with the input terminal.   A distributed constant line and an FET are connected  in  pair with  the  through  and  coupling  terminals, respectively,  the other end of the distributed constant line being connected with earth.   When the FET  is  turned on or off,  the  amount  of  phase  shift  in  the  phase  shifter  is controlled.   Since the FET and distributed constant line are connected together in parallel,  the amount of phase shift can be adjusted easily by turning the FET on or off.

Abstract: A superconducting device comprises first and second oxide superconducting regions of a relatively thick thickness formed directly on a principal surface of a substrate separately from each other, and a third oxide superconducting region of an extremely thin thickness formed directly on the principal surface of the substrate so as to bridge the first and second oxide superconducting regions. A barrier layer and a diffusion source layer is formed on the third oxide superconducting region, and an isolation region is formed to cover an upper portion or both side surfaces of the diffusion source layer. The first, second and third oxide superconducting regions and the isolation region are formed of the same oxide superconductor material, and the isolation region is diffused with a material of the diffusion source layer, so that the isolation region does not show superconductivity. Therefore, a superconducting current can flow between the first and second oxide superconducting regions through only the third oxide superconducting region.     For formation of the superconducting device, a first oxide superconductor thin film having a very thin thickness is formed on the principal surface of the substrate, and a barrier layer and a diffusion source layer are formed on a portion of the first oxide superconductor thin film. A second oxide superconductor thin film is grown on an exposed surface of the first oxide superconductor thin film until the two layers are embedded in the second oxide superconductor thin film, so that a material of the diffusion source layer is diffused into the second oxide superconductor thin film on an upper portion or both side surfaces of the diffusion source layer.

Abstract: A platinum-silicon powder is electrophoretically deposited on a nickel or cobalt base superalloy substrate.  The deposited powder is heated to form a transient liquid phase on the  substrate and initiate diffusion of Pt and Si into the substrate.  An aluminum-chromium powder is then electrophoretically deposited on the Pt-Si enriched substrate and diffusion heat treated to form a corrosion- and oxidation-resistant Pt-Si enriched diffused aluminide coating on the substrate.  The presence of both Pt and Si in the aluminide coating unexpectedly improves coating ductility as compared to a Pt-enriched diffused aluminide coating without Si on the same substrate material.

Abstract: ABSTRACT OF THE DISCLOSURE    A combustion apparatus for a refuse incinerator has a plurality of rows of grates arranged in parallel in the directions of breadth and in series in the longitudinal directions of a combustion zone and a post-combustion zone of the combustion apparatus. The rows consist of immobile grates and mobile grates alternately arranged.    Immobile girders support the immobile grates.   Mobile girders support the mobile grates.   A partition wall divides the combustion apparatus into the combustion zone and the post-combustion zone.   Seals cooperates with the mobile girders and are located on the partition wall.   A hydraulic cilinder shuttles the mobile girders.   Bearing housings are mounted on upper protrusions of the mobile girders holding the mobile grates so as to be able to vibrate.   The engagement between the bearing housing and the mobile grates in the post-combustion zone allows play in the direction of driving the mobile girders so that the working stroke of the mobile grates in the post-combustion zone is shorter than the working stroke of the mobile grates in the combustion zone.

Abstract: ABSTRACT           Home  financing  is  provided by means  of  a salary linked mortgage.  A borrower repays a loan from a  lender  by  paying  a  percentage  of  his  salary, irrespective of the manner in which his salary varies, for a predetermined period.  The percentage may be the same  for  the  entire  period  or  it  may  vary  in  a predetermined manner.  The lender may also unilaterally vary  the  percentage  if  the borrower does  not make payments  on  specified  dates.     Conveniently,   a convenience percentage value is used for each financial year and, if necessary journal entries are made.  The system is managed and supervised by data processing equipment which stores information characterizing each borrowers account, inputs details of repayments from the borrower and his employer, generates an updated schedule percentage for each account at the end of each month and communicates the updated schedule percentage for each account at the end of each month.

In the process, an aqueous phase which contains the olefinically unsaturated carboxylic acid, polymerisation initiator and 100 to 75% of the polysaccharide is metered into a dispension of 0 to 25% of the polysaccharide in a hydrophobic solvent at a temperature of from 40 to 100C.  The polymerisation results in a uniformly fine product with a narrow particle size distribution.  The product shows a rapid and high liquid absorption and is especially suitable for incorporation in cellulose-containing absorbent hygiene articles, such as dispos-able diapers and sanitary towels.

Abstract: A rail clamping device is provided for aligning and clamping the flange of a rail to a support surface. A slotted clip is fitted over an anchor bolt or other suitable connector, a plate cam washer having an eccentric hole is placed upon the clip, and a nut threaded upon the bolt to secure the clip and washer to the rail flange. The clip has a slotted base portion which slidably engages the support surface in a loose condition and bears upon the support surface in a clamped condition. An abutment portion extends from the base perpendicular to the support surface to engage the outer face of the rail flange. A cantilever portion extends forwardly from the abutment portion and has a bottom surface to which a synthetic rubber strip is bonded to engage the upper surface of the flange to clamp the flange to the supporting surface. The cam washer slidably engages the top surface of the base portion in a loose condition. The cam washer has an outer flank for engaging a rearward face of the abutment portion.      Preferably, the cam washer has a spiral cam profile such that the angular rotation of the washer upon the bolt results in substantially proportional lateral movement of the clip and abutting rail flange. The rail flange may be aligned by rotation of the cam washers of devices on opposing sides of the rail when in a loose condition and then clamped securely in place by rotation of the nut.
