Title: Karman vortex flowmeters
Inventor: MIYOSHI NORIOMI
IPC: F02M69/48
Filed: 1985-02-05
Abstract: A vortex detector has an oscillatory plate 90 which can oscillate, in response to conveyed vortex pressure changes pivotally about an axis along which extend torsional bands 100a, 100b, supporting the plate 90 in a frame 110 formed in unitary fashion with the plate 90 and torsional bands. Means are provided for tensioning the torsional bands and for damping their torsional movements, e.g. damping material 36. The damping material is applied on the bands 100a, 100b, or completely fills the vortex detector, to suppress resonance of torsional oscillation of the oscillatory plate. <IMAGE>

Title: Forming ceramic films
Inventor: STERLING HENLEY FRANK
IPC: H01G13/00
Filed: 1985-05-03
Abstract: A process for forming a film of a ceramic dielectric material comprises dispersing the ceramic material as a comminuted powder coated with an organic resin in a liquid medium, electrodepositing the ceramic powder and the resin from the dispersion on to a conductive substrate, and firing the film to form the ceramic, thereby removing the resin. In the examples the electrodeposition composition is prepared by sand milling or ball milling a mix comprising the ceramic, resin and water then diluting the mix with water. The process may be used in the fabrication of a ceramic capacitor having ceramic layers 11 and conductive electrodes 22. <IMAGE>

Title: Fuel injection pump for an internal combustion engine
Inventor: GUNTERT JOSEF
IPC: F02M59/26
Filed: 1985-07-30
Abstract: A fuel injection pump for an internal combustion engine has a control sleeve (5) axially displaceable on a pump piston (3) provided with an oblique control groove (15) connected to the pump working chamber (20) by a passage (19), the control sleeve having a discharge bore (22) for co-operating with the oblique groove 15 to end delivery.

IPC: A62C35/02
Filed: 1985-09-04
Abstract: A nozzle assembly 20 is connected to receive extinguishant under pressure from a vessel 10 when the discharge mechanism 12 of the latter is actuated. The extinguishant acts on the face 66 of a piston part 34 and exerts sufficient pressure to move the latter against a spring 52. A hollow sleeve 38, which receives the extinguishant through a small opening 60, thus slides in a section 26 response to the piston movement and holes 42 and 44 now protrude at the end of section 26 which was previously closed off by a cap 40 and end plate 46. In this way, the nozzle is normally completely closed off from pollution etc. in the external environment but is opened automatically by the pressure of the discharging extinguishant. <IMAGE>

Title: Improvements in quick-drying vehicles for coating materials
IPC: C09D11/06
Filed: 1959-07-22
Abstract: Non-aqueous vehicles for coating materials comprise a drying oil with conjugated double bonds, an oil-soluble organic peroxide and a tertiary amine.  The peroxide appears to catalyse drying of the composition on exposure to cold energy radiation, e.g. ultra-violet light or alpha rays.  The tertiary amine prevents livering or shimming.  Bodied tung oil is the preferred oil.  Many organic peroxides and hydroperoxides are mentioned.  Suitable tertiary amines are N,N-dimethyl aniline, triethylamine, triamylamine, and N-methyl morpholine.  Conventional driers, e.g. cobalt, lead or manganese naphthenates, octoates or linoleates may be included in the compositions.  U.S.A. Specifications 2,453,769 and 2,453,770 are referred to.

Filed: 1986-07-15
Abstract: There is proposed a multi-layer armour which consists of (preferably light) metal layers (11, 13) and at least one ceramic layer (12). In addition, a pure metal layer (13) is applied to one plate or to a shaped part (11) by thermal spraying, which layer follows further layers (14, 15) produced in the same way, in which a part of the metal in the spraying material is gradually replaced by a suitable ceramic (e.g. aluminium oxide or titanium carbide) until finally a pure ceramic layer (12) is applied. Further layers, in which again a part of the ceramic is replaced by metal can follow until again a covering layer of pure metal is obtained. Further layers can be provided which serve for the screening against radio-active radiation (17, e.g. of boron carbide) or against electromagnetic impulses (18, e.g. of copper).

Title: Continuous Wave Radar Altimeter
Inventor: WALLS RAYMOND JOHN
IPC: G01S13/88
Filed: 1987-06-10
Abstract: A continuous wave radar altimeter comprises a pulsed power control (4), operable when the signal-to-noise ratio of the received signal is likely to be too low, or independence upon flying height, to pulse the transmitted power so that the power varies between a the continuous wave base level and a higher level.

Patent GB-2210104-A (GB)
Title: Gas turbine engine and mounting
Inventor: NEWTON ARNOLD CHARLES
IPC: F02C7/20
Filed: 1987-10-14
Abstract: The upstream portion of a gas turbine engine 10 is connected to a pylon 48 which in turn is fastened to an aircraft wing main beam. The connection is made by way of a pin 50 on the pylon slidingly located in a spherical bush 42 which is fixed in a completely annular flange 40 which is connected to the gas turbine engine compressor casing 24 via a casing 30. Ovality of the upstream portion of the engine 10 is reduced by the conversion of the vertical and lateral loads generated by inter alia the weight of the engine, through the total peripheral contact of the flange 42 with the casing 30, rather than by point contact as would be achieved by peripheral links. A pair of links (52, 54) (Fig 3) may be provided by transmitting thrust loads to the pylon 48. <IMAGE>

The alloy may contain 1-30 wt % Cr and consists mainly of Al, Cr and (-) phase (Al13Cr2). Numerous examples of specific alloys are provided. The Al-Cr alloy may be formed as a second layer over a first layer of Si, Cu, Al-Si alloy, Al or Cr alloy and in one embodiment the Al-Cr alloy is deposited over a Cr deposit layer and the Al-Cr alloy is covered with an Al deposited layer. A ternary or multi-component Al alloy layer may be deposited, the other alloying ingredient preferably being Si or Ti. The alloy layers may be deposited by physical vapour deposition using plural deposition sources, ion plating or sputtering. Plural deposition sources are used to produce deposited layers in which either the chromium content gradually increases with distance across the thickness of the layer such that the Cr content is minimum at the interface between the layer and the substrate metal or the chromium content gradually increases with distance across the thickness of the layer such that the Cr content is maximum at the interface between the layer and the substrate metal. The plated product finds use in automotive exhaust mufflers, store heat reflectors and building materials. The substrste may be steel, Al-alloy or Cu-alloy.
