Title: Portless type master cylinder device with non return valve and restricted passage in parallel between pressure chamber and fluid reservoir
Inventor: SAKAMOTO SHIGERU
IPC: B60T11/20
Filed: 1986-10-16
Granted: 1991-01-22
Abstract: ABSTRACT OF THE    DISCLOSURE In this portless type master cylinder device, a cylinder bore is formed in a body thereof, and a piston member is fitted in the cylinder bore and is slidably movable from an initial axial position therein and defines a pressure chamber in cooperation with the cylinder bore. An intake valve communicates between the cylinder chamber and the fluid reservoir via a fluid flow path, and is opened when the piston member is in its initial axial position while it is closed when the piston member moves through more than a determinate relatively small axial distance from its initial axial position. Intermediately along the fluid flow path between the intake valve and the fluid reservoir, there are provided in parallel a non return valve which allows substantially free flow of fluid from the fluid reservoir to the intake valve but not substantially in the reverse direction, and a means for allowing flow of fluid from the intake valve to the fluid reservoir with a relatively high flow resistance being presented to the flow. Thereby, the stroke of the piston member has a much reduced inactive initial stroke portion, as compared with other portless type master cylinder devices, and the operational feeling of the master cylinder device is greatly improved.

Title: Forward converters used in switching power supplies
Inventor: FRAIDLIN SIMON
IPC: H02M3/28
Filed: 1986-12-18
Granted: 1991-05-14
Abstract: FORWARD CONVERTERS USED IN  SWITCHING POWER SUPPLIES     Abstract A forward converter periodically resets the transformer core to prevent saturation and returns magnetizing energy to the energy source, requiring only the addition of one resonating capacitor to the converter circuit.          The transformer is reset and the energy recovered into the input voltage source by resonant commutation of the magnetizing current between the magnetizing inductance and a resonating capacitor.  A resonant current path is completed during a nonconducting interval of the power transistor switch through the resonating capacitor, shunting the output rectifying diode connected to the secondary winding, and the flyback diode of the output filter to permit transfer of the transformer's magnetizing energy to the input energy source.  This magnetizing energy transfer from core to capacitor to input energy source has a resonant quasi-sine waveform and utilizes the resonant properties of the network to enable its flow back into the input voltage source.

Title: Camshaft and method for its production
Inventor: SUTER GEOFFREY M
IPC: F01L1/04
Filed: 1987-07-03
Granted: 1991-10-01
Abstract: ABSTRACT      A camshaft for an internal combustion engine is produced as a tubular fabrication by assembling a plurality of initially circular cam rings 12 on a central tubular member 10, deforming the cam rings to a desired cam profile by pressing in die cavities 20-22 of a forming tool and then radially outwardly expanding the tubular member into the shaped cam profile rings by the application of internal fluid pressure to the tubular member 10.  The shaped cam rings 12 are thereby secured against rotational and axial movement relative to the tubular member 10.   Alternatively, the pressing of the cam rings to a desired cam profile may also deform the tubular member relative to the cam rings to such an extent as to secure them to the tubular member without recourse to the subsequent application of internal fluid pressure to the central tubular member.

Title: Solid flowable polymer medium with metal additives and method of molding using same
Inventor: KROMREY ROBERT V
IPC: B22D19/00
Filed: 1987-09-09
Granted: 1993-05-25
Abstract: Abstract Solid Flowable Polymer Medium with Metal Additives and Method of Molding Using Same A flowable particulate polymer-metal mixture that is thermally conductive and is particularly adapted for use as a pressurizing medium in a high pressure elevated temperature molding process.  The material comprises a substantially uniform mixture of about 20% to about 90% solid flowable, particulate silicone rubber having a nominal flow rate of at least 0.6 gram/second through a 1.1 cm diameter pipe 7.6 cm long under applied pressure of 10.34 MPa at room temperature.  The material also comprises about 10% to about 80% thermally conductive particulate metal that has a melting point less than the molding temperature and is substantially chemically compatible with said silicone rubber.  The pressurizing medium is used to mold article precursors into articles by placing an article precursor within a pressure vessel and substantially filling the vessel with a pressurizing mixture.  The mixture is exposed to a temperature equal to or greater than the metal melting point and is caused to produce a substantially uniform predetermined medium pressure on the surface of the article precursor to mold the article.  The molten metal transfers heat to the article precursor yet since it is molten the polymer-metal mixture is flowable.

Title: Apparatus for manufacturing a plastic hollow body, which has a slidable mandrel
Inventor: LINSS GERHARD
IPC: B29C49/02
Filed: 1988-02-11
Granted: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus, intended for manufacturing a hollow body which hollow body has a head piece formed by blow-molding a preform segment, is comprised of a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally reciprocally movable.  It is desired that regions of the hollow body being fabricated have outer diameters which are less than the diameter of the extruded tubular segment before said segment is blown.  This is achieved in that a reciprocally movable mandrel with a molding extension is provided which extends between projecting regions of the blow-mold pieces, which projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against said molding extension, whereby the ring-shaped nozzle opening is radially outwardly offset with respect to the outer contour of the molding extension.  Following the extrusion, the molding extension is advanced and serves as an implement form forming the inner shape of the reduced-diameter region of the body part, and as an opposing thrust element for the blow-mold pieces which press together regions of the tubular preform segment.
