摘要:
This invention relates to composites for use in high temperature elastic composite applications. Most particularly, this invention relates to elastic composites formed with a silanol-silanol condensation reaction mixture of silsesquioxane silicone resins thermally stabilized by boron nitride, silica and boron oxide additives as their matrix. The polymer matrix composite comprise a matrix of cured high, intermediate and optionally low molecular weight silicone resins including boron nitride and silica additives and reinforcing material.

A first embodiment of carousel device provides a bouncer which cannot be tipped over accidentally. Further, a oscillating circuit enables a battery-operated motor to gently oscillate the bouncer through an 80° arc. A pair of retractable rockers are provided on the bottom of the stationary base to afford the baby additional motion while bouncing. A second embodiment provides a straddlable vehicle which a youngster can peddle, a sound circuit being activated by the pedaling as inducement to continue exercising.
摘要:
A composite device assembled into a top of a head combustion chamber as a formed in place multiple spark ignition structure with embedded electrodes connected in a series electrical circuit spaced from a single centrally located ignition source to receive an arc from a central spark plug electrode to initiate a series multiple spark ignition within the series electrical circuit.

This invention extends the elastic range of silicone composite gaskets from typically −40 to 300° C. (Reference I) to temperatures within the “red heat”, Le, 600 to 1000° C. applications The composite gaskets comprise a matrix of cured methyl and/or phenyl-silsesquioxane resins, boron oxide, boron oxide and silica additives and a reinforcing material that enables highly thermally stable elastic composites to be fabricated into durable composite exhaust system gaskets The invention offers the most economical and proven durable solution to the current high temperature sealing problems (Reference 2) and cost of current traditional multi-layer steel gaskets The method for making the composite gaskets comprises applying the above resin blend to continuous or discontinuous fiber reinforcing material and curing the resin
摘要:
This invention describes how a blend of silicon polymers, mixed with the right combination of fillers applied to fiber reinforcement laminated with an embedded circuit and laser cut into vacuum formable preforms enables the production of “red heat” durable flexible ceramic multiple spark ignition devices which are vacuum formed into the head combustion chamber of IC engines for realizing fuel savings from up to 33% increased combustion efficiency. The MSI device also comprises a spark plug which is made with the steel adjustable grounding gap section removed. The spark plug electrode alignment for the fuel injectors is also used to align the spark plug electrode to insert during assembly into the MSI device (see FIG. 1) circuit port. This electrode insertion enables the electrode to arc within the 360° gap of the circuit port setting off the “in series” arcing of the two other electrodes within the surround combustion circuit completing the drop in potential at the ground attachment (see FIG. 1). This innovation allows the plugs to be inspected and changed as is common to current engine maintenance schedules. Since only three electrodes are needed to provide the fuel savings, only two electrodes beyond the central plug are needed to realize the fuel savings. The FIG. 1 drawing provides 4 separate electrodes which may be fired in any combination with the central spark plug. The two extra electrodes are designed with a keeper that prevents the gap from firing until it is cut; this leaves the two electrode gaps in reserve for future use if needed. The MSI device attachment is designed for maximum contact with the head combustion chamber's intake valve zone while avoiding the exhaust valve port area using optional laser cut lightener holes and cut away zones which are ceramically sealed by the laser cutting at 16,500° C. These MSI devices can be retrofit on “after-market” trucks and automobiles also providing these existing vehicles an affordable increase in combustion efficiency fuel savings.
摘要:
A basketball-like member is mounted on one end of a pendulum adapted to swing in an arc about a cylindrical bearing attached to a support extending from a discontinuity of a first side of a partially cylindrical hoop through which the basket-ball member is repetitively swung to score points. A handle on a second opposite side is grasped and the tethered ball manipulated to cause the repetitive arcuate travel through the hoop. A battery-powered counter keeps track of the number of baskets or points scored, at the preference of the player.

A stroller has a pivotable seat which may be latched at any rotational angle desired. In addition, a support tray positioned beneath the seat can be folded into a stored position and the height of the support platform adjusted to accommodate the height of the baby occupying the seat, which permits the stroller to be used as a walker and as a play station.
