Title: Process for producing toners for use in electrophotography
Inventor: YAMASHIRO JIRO
IPC: G03G9/08
Filed: 1988-06-28
Granted: 1993-03-02
Abstract: Abstract of the Disclosure Disclosed is a process for producing toners for use in electrophotography which comprises: stirring a mixture of a radical polymerizable liquid monomer and carbon black in the presence of a peroxide polymerization initiator, thereby to disperse the carbon black uniformly and minutely in the monomer; adding an azobisnitrile polymerization initiator to the resultant monomer composition; suspension polymerizing the monomer in an aqueous medium: and recovering and drying the resultant spherical polymer particles.  In a preferred manner, the suspension polymerization is carried out in an aqueous medium which contains polyvinyl alcohol as a suspending agent, and after the polymerization, the polyvinyl alcohol remaining on the polymer particles is saponified or nitrated to produce a toner with a higher quality.

Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE         A combination cot and backpack having first and second equal sized rigid frame sections which are hinged together at one end and pivot between a closed position to form a backpack and an open position to form an elevated cot.  First and second sheets of flexible material are laced tautly between side portions of the first and second frame sections.  A third frame section telescopes out from the second frame section to provide additional length for the cot.  The third frame section is covered by a third sheet which unfolds from the second sheet and is held tautly by connectors underneath.  The frame sections are made of tubular aluminum and have rigid downwardly extending u-shaped cross portions which provide legs for the elevated cot.  Removable elongated storage pouches fit between the hinged frame sections in the closed position.  A detachable carrying harness extends from a closure strap with a buckle which extends around the pack to hold it in the closed position.

Title: Joining metal tubes
Inventor: HARDWICK ROY
IPC: F16L13/14
Filed: 1988-08-30
Granted: 1991-09-24
Abstract: ABSTRACT "Joining Metal Tubes"     A metal tube is expanded by means of an explosive charge into engagement with a surrounding tubular metal member which is supported externally by a surrounding metal die member spaced from the metal member, the intervening space being filled with a shock transmitting liquid such as water.  The metal die member is readily separate from the expanded tube and is reusable indefinitely without maintenance.  Its use is, therefore, more economical than the split die hitherto used.  The method is especially useful for expanding large diameter tubes, for example, expanding oil-well drill pipes into pipe coupling members.

Title: Angioplasty dilating guide wire
Inventor: WILLARD LLOYD K
IPC: G01M3/26
Filed: 1988-11-14
Granted: 1992-07-21
Abstract: Abstract of the Disclosure A dilating guide wire (12) for use in percutaneous transluminal angioplasty (PTCA) has a very small outside diameter which permits it to be used with a PTCA catheter (100, 101, 105) for treatment of tight stenoses in the coronary arteries that cannot be treated by conventional PTCA catheters alone.  The dilating guide wire (12) is small enough to pass through the through lumen (115) of the PTCA catheter and extend beyond the distal tip thereof for predilating the stenosis to permit subsequent crossing and dilation by the PTCA catheter.  Means (60, 140) may be provided for selectively imparting an axial force to the balloon (20) of the dilating guide wire to cause axial stretching thereof, thereby reducing its profile and facilitating withdrawal of the balloon of the dilating guide wire back into the PTCA catheter.  This may be accomplished through manual actuation of a control knob (65) attached to the core (14), or in another embodiment, automatically through permitted limited movement of the core (132) relative to the outer tubing (130) of the dilating guide wire as the control manifold (140) is moved forward or backward.

Abstract: Round Baler with Continuous Bale Size Monitoring Abstract of the Disclosure A potentiometer is driven by one of the serpentine arm assemblies used to maintain apron tension during formation of a round bale so that the output of the potentiometer continuously provides an indication of the size of a bale being formed in the baler.  A microprocessor based control circuit senses the output of the potentiometer, converts it to a digital value, and compares the digital value with a value representing a desired bale size.  When the two values are equal, the microprocessor computes the number of revolutions of a net feed roll that is required to wrap the bale a preselected number of times, energizes the net feed roll mechanism to feed net into the bale forming chamber, and counts the revolutions of the net feed roll.  When the required amount of net has been dispensed, the microprocessor stops the net feed roll and activates a mechanism to cut the net.  The size of a "full bale" is selected by actuating keys on a control panel.  An offset is automatically provided to compensate for wear in the apron mechanism affecting the "zero" setting of the bale size sensor.  The system permits signalling the operator to steer left or right along a windrow to control bale shape as the bale being formed in the chamber increases in diameter, the signalling rate being non-linear with respect to bale diameter.

Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.

Abstract: This invention relates to a roof construction, preferably intended to be arranged on a roof of a slight fall and comprising a plurality of supporting plate profiles (1:1') which are put on crossbars (6) or the like, said plate profiles (1:1') being placed in a certain spaced relationship. At roofs having a slight fall, so-called plane roofs, it has so far been impossible in principle to use outer roof covering, as inleakage of water has been a great problem.
