Abstract: Abstract Cooling body for the liquid cooling of high-power semiconductor components In a disc-shaped cooling body (1) which has, in the semiconductor supporting surface illustrated, cooling slits (3) which are connected via two connecting channels (4) to a collecting channel (7) for the supply of a cooling liquid, for example oil, cooling elements (9) are provided at the edge to improve the cooling effect.  These cooling elements can be designed as cooling ribs, cooling fingers or cooling needles.  The cooling liquid flows out of the cooling slits (3) at an angle (?) of preferably 60° to 70°, so that it flows over a relatively long distance along the outer edge of the cooling body (1) and between the cooling elements (9) of the latter and thereby dissipates heat from the cool-ing body and from the cooling elements.  The cooling slits can extend radially, widening outwards, or in serpentine or involute form or spirally and can have a rectangular or triangular or semi-circular or trapezoidal cross-section.

Abstract: ABSTRACT OF THE DISCLOSURE     A capacitive pressure transducer of the deflecting diaphragm type is adapted to be coupled to a capacitance transducing circuit and includes a generally planar, electrically conductive base member supported upon a first insulative substrate.  A sensor member is supported upon a second insulative substrate in a generally parallel, spaced relationship from the base member and coacts with the base member to form a sensor capacitor.  A reference member is generally coplanar with and in electrical isolation from the sensor member and coacts with the base member to form a reference capacitor.  The sensor and reference members each have a plurality of segments interposed one with another.  The sensor and reference capacitors have pressure-dependent capacitance values Cs and Cr respectively such that, for discrete pressures selected within an operative range of pressures, the output signals from the transducing circuit will be substantially linear.   A method for making a deflecting diaphragm type capacitive pressure transducer adapted to be coupled to a capacitive transducing circuit includes the steps of providing a conductive base member supported upon a first insulative substrate and providing a second insulative substrate having a generally planar surface adapted to be disposed in a generally parallel, spaced relationship to the base member.  A plurality of concentric circles is superimposed upon the planar surface to define a plurality of annular rings.  Each ring is apportioned into a plurality of sensor incremental areas and a plurality of reference incremental areas.  Electrically conductive sensor and reference members are disposed in a continuum upon the sensor and reference incremental areas, respectively, in electrical isolation one from the other and coact with the base member to define sensor and reference capacitors, respectively.  Apportioning is performed in a manner so that the sensor and reference capacitors have pressure dependent capacitance values such that for pressures occurring within an operative range, the output signals from the transducing circuit will be substantially linear.

Abstract: METHOD OF FABRICATING COMPOSITE OR ENCAPSULATED ARTICLES                      ABSTRACT A method for molding composite articles or encap-sulating an article is disclosed wherein an article to be encapsulated or molded and a heat curable thermosetting resin are loaded into the cavity of a mold, which has been preheated to the curing temperature of the resin. The mold is then evacuated to a subatmospheric pressure to impose a vacuum on the mold in order to impregnate the article with the resin and to degas the mold contents. The vacuum is thereafter released to burst any gas bubbles remaining in the mold contents.  Superatmospheric pressure is then applied to the mold contents to cause the resin to encapsulate the article.  The temperature and the superatmospheric pressure conditions are maintained for a time sufficient to partially cure the resin and form a unitary structure which is ejected from the mold.  The structure ejected from the mold is subjected to a further heating cycle to completely cure the resin.      Composite articles so formed are useful as structures, such as antenna waveguides, for space applications.  Electrical components encapsulated by the process of the present invention have a high-reliability passivation layer.

Abstract: ABSTRACT OF THE DISCLOSURE    A child's battery-powered riding toy includes a floorboard with two spring-biased switches that must be closed by the child operator to place the vehicle in self-powered motion and can only be reached simultaneously of the child operator is safely aboard.  The battery power supply is capable of providing high or low voltage to the motor drive, but a reversing switch is connected between the battery power supply and the motor drive, and it must be in its "forward" position to receive the high battery voltage.  In its "reverse" position, the reversing switch separately connects the motor drive to only the low battery voltage.  The spring-biased switch connected directly to the reversing switch has a dynamic braking load connected to it to be placed across the motor drive when the reversing switch is in its "forward" condition and the latter spring-biased switch is allowed to be under the control of its biasing spring.  The floorboard is supported by hangers from the frame of the toy vehicle and is connected by snap-fastener components to the hangers.

Abstract: ABSTRACT OF THE DISCLOSURE            Novel cementitious and non-cementitious ferrofluids are disclosed which have properties making them suitable for use in cementing wells.  The cementitious fluids comprise:  (a) a hydraulic cement, (b) finely divided magnetic particles, (c) a binding agent or a surfactant, and (d) a liquid medium.  The binding agent or surfactant is present in the compositions in an amount sufficient to render the compositions stable in a magnetic field.  When used in cementing wells, the cementitious ferrofluids are implaced in the annulus separating a casing from the formation in a wellbore by conventional techniques and the slurry is subsequently subjected to an activating magnetic field that causes movement of the magnetic particles in the slurry. The non-cementitious ferrofluids comprise   (a) finely divided magnetic particles, (b) stabilizing agent, and (c) a liquid medium.  The movement of the magnetic particles results in a "scrubbing" action against the surface of the casing and the formation and a mixing of the slurry which helps displace any residual drilling mud.  The net result is better bonding of the cement.
