Abstract: ABSTRACT OF THE DISCLOSURE A solvent vapor toner image fixing device for use with electrostatic devices is disclosed.  The fixing device includes a fixing station having a well-shaped receptacle through which the paper web or the like is guided in a loop shaped manner.  At the bottom of the receptacle a solvent vapor producing zone is provided through which the paper is passed.  After leaving the solvent vapor fixing zone, the paper is guided out of the receptacle around a deflec-tion cylinder.  The solvent vapor zone is limited by cooling coils positioned above the fixing zone.  The deflection mechanism for looping the paper through the receptacle is removable from the receptacle to allow ease of installation of the paper.

Abstract: Abstract of the Disclosure The present invention relates to a structure comprising a semiconductor body whose bulk is of one conductivity type and which has a major surface, a localized first region which is of the one conductivity type, and a localized second region and a localized third region which are both of the opposite conductivity type. Each of the localized first, second and third regions are of relatively low resistivity as compared to the bulk portion of the semiconductor body and are spaced apart from the others. Separate electrodes are connected to each of the first, second and third regions  The localized first, second and third regions each have a portion thereof which forms a part of the major surface. The semiconductor body is separated from a semiconductor wafer (substrate) by a dielectric layer.  The semiconductor wafer (substrate) is adapted to facilitate connection to an electrode and is characterized by a localized fourth layer of the same conductivity type as the third region. The fourth layer is sandwiched between the dielectric layer and the semiconductor body.

Abstract: Abstract An energy-absorbing preloaded pad assembly for use in stabilizing relatively movable portions of a structure, such as vehicle structure.  The stabilizing pad assemblies may be utilized for stabilizing oscillations of a stabilizer bar relative to a frame of a vehicle and may include preloaded pads.  A removable clamp cooperates with a cover plate of the pad assembly to provide the desired preload to the pad and permit facilitated installation of the stabilizer bar in the vehicle structure, such as to permit ready installation of the pivot structure.  upon assembly of the vehicle structure, the removable clamp is disassembled permitting reuse thereof with other similar pad assemblies.  Removal of the clamp frees the pad for stabilizing functioning in the assembly in the normal manner.  In one form, the pad baseplate is secured to the stabilizer bar by bolts disposed substantially at the neutral axis of the stabilizer bar and in another form, the baseplate is retained on the stabilizer bar by a pair of downwardly turned securing portions and an end tongue.

Abstract: Abstract An apparatus for and a method of pressing and draining whey from cheese curd particles in manufacturing large sized blocks of cheese.  Cheese curd is placed into a pressing container mold which has a removable internal draining means having dimple-like projections maintaining a space between the plates of the screen.  In one embodiment of the invention, pressure is applied in a vertical direction on the curd particles uniformly draining the whey.  The drain means is extracted, and a second application of pressure closes remaining interstitial voids.  In a second embodiment of the invention, a first application of pressure is applied to the curd particles in two separate directions at the same time.  A spreading spade is inserted between substantially vertical parallel foraminous plates thereby moving these plates further apart exerting a relatively horizontal force on the curd particles and, in conjunction, a press plate pushes down on the curd particles exerting a relatively vertical force on the curd particles.  As a result, the whey is uniformly drained and the curd particles are substantially fused.  The internal draining means is then extracted and a second application of pressure substantially closes interstitial voids remaining from the first application of pressure.  A flexible plastic liner covers the curd particles and the container is closed.  The container is subjected to a vacuum chamber whereby the curd is further compressed causing free whey to run out and removing air bubbles, whereby the flexible plastic liner is sealed to the curd particles.  The pressing container mold is then ready for storage or shipping.

Abstract: ABSTRACT OF THE DISCLOSURE         When a steel sheet or the like  is heated in a furnace to a temperature somewhat higher than the room temperature and is still or moved, its temperature can be measured by detecting the radiant energy therefrom. The measurement is normally difficult due to the influence of background noise of radiant energy from the surroundings, change of the transmit-tance factor of the environment or atmosphere for radiant energy, and change of the emissivity of the object to be measured.  In order to remove such causes of errors and to correctly measure the temperature by detecting radiant energy, a radiometer and a black body radiator are disposed symmetrically and specularly with respect to the normal to a surface of an object to be measured, and two different amounts of radiant energies are emitted from the black body radiator, and the emissivity of the object to be measured is determined from the detected values from the radiometer, the two temperature values of the black body radiator, and the diffusely reflecting factor associated with the object to be measured, whereby correct measurement of the sur-face temperature of the object to be measured can be done.  Embodiments for implementing this method are pro-posed.

Abstract: ABSTRACT OF THE DISCLOSURE         A tire-changing machine has a framework provided for supporting a wheel rim receiving platform adapted to receive and secure thereon a wheel rim having a drop center.          A bead breaker mechanism includes an upper bead breaker shoe operatively connected to a bead breaker drive through an upper bead breaker lever which is pivotally mounted on the framework.  An upper bead breaker shoe support column is coupled to the upper shoe at an upper end and pivotally connected to the upper bead breaker lever at a lower end.          The pivot between the bead breaker lever and the framework is positioned below the pivot between the bead breaker lever and the support column when the upper bead breaker lever is not actuated.  An elongate link is pivotally attached to a point intermediate the ends of the support column at one end and the framework at the other end, the attachment between the link and the support column being at or below the pivot between the link and the framework when the upper bead breaker lever is not actuated, whereby downward motion imparted to the support column by actuation of the upper bead breaker lever causes the upper shoe to move inward and downward toward the drop center of a wheel rim on the rim receiving platform.
