Title: An investment casting technique for the formation of metal matrix composite bodies and products produced thereby
Inventor: BURKE JOHN THOMAS
IPC: B22F3/26
Filed: 1989-10-13
Granted: 2002-01-15
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and the novel products produced therefrom. A negative shape or cavity, which is complimentary to the desired metal matrix composite body to be produced, is first formed. The formed cavity is thereafter filled with a permeable mass of filler material. Molten matrix metal is then induced to spontaneously infiltrate the filled cavity. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material, at least at some point during the process, which permits the matrix metal, when made molten, to spontaneously infiltrate the permeable mass of filler material, which at some point during the processing, may become self-supporting. In a preferred embodiment, cavities can be produced by a process which is similar to the so-called lost-wax process.

Inventor: GREENWOOD CHRISTOPHER JOHN
IPC: F16H15/38
Filed: 1989-11-20
Granted: 1999-12-21
Abstract: A roller control system for a continuously-variable-ratio transmission of the toroidal race, rolling traction type, in which rollers of variable orientation transmit traction between a part-toroidal race formed on an input disc and a similar race formed on a coaxial output disc. Each roller is mounted to rotate about a fixed centre and a fixed axis within a rigid carriage, one end of which contacts operating mechanism reciprocable over a predetermined stroke of operating movement and operable to apply a control force to the carriage. The assembly of roller and carriage is located by only three contacts with adjacent structure, namely the two disc/roller contacts and the contact with the operating mechanism. These three contacts suffice to cause the roller constantly to seek a ratio angle at which the instantaneous value of the control force is balanced by the instantaneous value of the traction forces to which the roller assembly is subjected due to the contact between the roller and the two discs, and at which the transmission is therefore in equilibrium.

Granted: 2001-04-10
Abstract: The present invention relates to a mold for producing a multilayer molded article which article is comprised of a resin body and a skin material on a surface of the resin body. The mold consists of male and female molds, wherein the shortest horizontal distance of a mating gap between the horizontally outermost wall surface of the male mold to which the skin material contacts and the horizontally innermost wall surface of the female mold to which the skin material contacts is 0.25 to 3 times the minimum thickness from which the once compressed skin material can restore to the original thickness. In addition the shortest length L in a mold closing direction of a mated part formed between the outermost wall of the male mold to which the resin melt contacts and the innermost wall of a flange of the female mold satisfies the equation: (t1 - t0 + 10) mm ~ L ~ (t1 - t0) mm.      In this equation t1 is a distance (mm) between the male and female molds when the resin melt first reaches the horizontally outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1 when the mold closing is completed.

Title: Planar slotted antenna with radial line
Inventor: GOTO NAOHISA
IPC: H01Q21/00
Filed: 1990-08-17
Granted: 1995-06-13
Abstract: The invention provides an inner-feed-type planar antenna of single-layered structure excited by an axially symmetric mode for propagating radio waves from the center toward the outer periphery within a propagation layer having an antenna surface.  If the planar antenna is used for transmission, the antenna is provided with a plurality of coupling slots formed and arrayed in one surface of an axially symmetric mode waveguide member in such a manner that the coupling factor of the external radiation is high at the outer periphery and becomes successively lower as the center is approached.  A spiral- or ring-shaped terminating slot is provided in the antenna surface at the outer portion of the axially symmetric mode waveguide member.  A region not coupled with the outer portion is provided at the center of the antenna surface.          Furthermore, the planar antenna is provided with a reflector member arranged along the terminating slot for reflecting a propagating radio wave between the inner and outer portions of the axially symmetric mode waveguide member.  Accordingly, a comparatively flat aperture distribution in which the electromagnetic field is uniform can be obtained.  In addition, by providing the central portion with a non-radiating region, long-line effect is suppressed and bandwidth enlarged.

Granted: 1999-09-07
Abstract: Disclosed is an agitator including an agitation shaft at the center of the agitator vessel, an agitator blade mounted on the agitation shaft and consisting of a flat-plate-shaped blade disposed along the inner surface of the bottom wall of the agitator vessel and a grating-shaped blade continuous with the flat-plate-shaped blade, a baffle plate vertically extending for rotation around the agitator blade along the inner surface of the side wall of the agitator vessel, and drive equipment for rotating the baffle plate and the agitator blade independently from each other. When the agitator blade and the baffle plate are rotated at different speeds, circulating flow is formed in the vessel. The grating-shaped blade at the upper portion of the agitator blade shears a part of the circulating flow which descends along the radially inward agitation shaft, thereby dividing that part of the flow into small parts. The small parts of the liquid are efficiently mixed together by the action of minute swirls generated behind the components of the grating-shaped blade.

Abstract: 2050923 9110563 PCTABS00006 A lead-free composition capable of being applied as a film and hardening to form a protective layer on the back of a mirror comprises a fluid organic resin and a corrosion inhibitor selected from the group consisting of dicyandiamide, metal or acid salts of dicyandiamide, hydrogen cyanamide, and 2-cyanoacetamide. The organic resin may be any thermoplastic or thermosetting resin suitable for coating the reflective and other metallic layers of the mirror. Exemplary resins include alkyd resins, acrylic resins, modified alkyd resins, polyesters, urethane oils, vinyl halide polymers or copolymers, oleoresinous varnishes, nitrocellulose compositions, phenol-formaldehyde resin varnishes, and epoxy resins.  Preferably, the resin is an alkyd or modified alkyd resin. The aforementioned corrosion inhibitor may be present in an amount from about 0.1 to 20 weight percent, preferably 0.5 to 10 weight percent, of the organic resin coating system. The resin system should be essentially free of lead and lead salts. To inhibit the corrosion of metallic film layers on mirrors, a mirror having a glass substrate layer and a metallic film layer thereover should be obtained, after which the fluid organic resin coating system containing the aforementioned corrosion inhibitor is applied over the metallic film layer. The organic resin coating system is then hardened to produce the protective coating layer over the metallic layer.  Other articles having metallic surfaces may also be protected by the resin system containing the novel corrosion inhibitor of the present invention.

Title: Two-channel forked light barrier in fail-safe construction

Granted: 2003-06-17
Abstract: Two-channel forked light barrier in fail-safe construction IP 1002 / Hergiswil, 31 October 1990 Sg/tb Summary:        A two-channel forked light barrier in fail-safe construction for the production of a shaft information in the region of the storeys for the premature opening of the doors on arrival of the cage displays a cyclical dynamic self-monitoring (ZDU, 6), by means of which a prophxlactic.fault recognition.. is possible. The ZDU (6) on arrival and standstill of the cage at a storey periodically simulates genuine operational sequences in that a brief emergence of the switching vane is simulated by optical short-circuit of the FS light barrier. The thereby effected interruption of the relay feed is however shorter than the release time of the relays so that. these do not release when the circuit is intact. A sequential course of timing signals (tA/B1 to 4, tVB) controls the sequence of the self-monitoring functions. In the case of any kind of component faults, this run-down is disturbed and a corresponding reaction in the safety circuits of the lift control takes place by way of relay contacts. A cyclically appearing test signal (TSA, TSB) is the primary control signal for simulated interruptions.
