Abstract: CARTRIDGE FOR CORRECTION MEDIA OR                TACKY TAPE WITH A WRAP SPRING                    Abstract of the Disclosure A typewriter correction tape cartridge for holding and feeding correction tape for a correcting typewriter is improved by the addition of a beam spring cantilever supported such that one end of the beam spring wipes the correction tape onto the takeup spool.  This will act to eliminate bubbles, wrinkles and crimps in the tape as it is placed in a new convolution on the spool and will thus reduce the outside diameter of the ultimate disc of used tape.  The advantage of this spring is that a reduced size cartridge may be used while utilizing the entire volume of tape supplied on the supply side of the cartridge and, secondly, a more reliable takeup is accomplished due to the elimination of irregularities in the takeup disc.  Where space considerations dictate that the spring be bent back sufficiently to accommodate a full spool without contacting the disc of ribbon accumulated on the takeup spool, the cross section of the spring, at a point near the anchor point, may be reduced by notching to provide a stress concentrated flex point and allow the spring member to still perform its function without premature engagement with the disc at a point other than at the wiper end.

Abstract: ABSTRACT OF THE DISCLOSURE     An orthodontic bracket of the type intended for cementing directly to a previously etched surface of the tooth enamel is made by applying to the lingual face thereof that contacts the tooth enamel surface a thin porous layer of sintered metal powder which is arranged to have a porosity such that it has keying characteristics close to that of the etched enamel and thereby facilitates the cementing adhesion of the bracket to the tooth.  A particularly suitable metal powder consists of particles of the same alloy as the bracket metal and of size in the range about 10 to about 150 microns (-100 mesh), preferably from about 10 to about 50 microns (-300 mesh) applied in a thickness of about 0.05 to 0.2 mm, by means of a sintering operation that fuses the particles to the lingual face and to one another.  The porous layer preferably is pre-filled with a polymer material compatible with the bonding cement, such as the sealant employed with the cement, so as to protect the layer against mechanical damage caused by bending of the bracket by the orthodontist to conform the bracket surface more closely to the tooth surface to which it is to be applied.

Abstract: TITLE PROCESS FOR THERMOFORMING REINFORCED      POLYMER SHEETS    ABSTRACT Reinforced poly(ethylene terephthalate) sheets are thermoformed to articles having one or more surfaces in contact with the mold of such a degree of smoothness that they virtually completely replicate the mold face.  When the mold face is completely smooth, the concave imperfections caused by air entrapment in the plastic material account for less than 6% of the surface area.  Composite articles consisting of a face member and a backing member are made by thermoforming in a single mold a face member having one or more surfaces in contact with the mold face of such a degree of smoothness that it completely replicates the mold face, and its proportion of concave imperfections is less than about 6% of the surface area.  The backing member is bonded in the mold with an adhesive to the face member, and the composite structure is allowed to remain in the mold for a sufficient time to permit subsequent removal without distortion.  The initial polymer sheets are less than about 5% crystalline, but the thermoformed article is left in the mold until it crystallizes to the desired degree.

The coating is formed from a bismuth oxide-silver-bismuth oxide multilayer system in which a more electronegative substance, i.e. a substance with a higher normal potential, is added to the bismuth oxide layers to avoid blackening under UV radiation.   If manganese is used as the electro-negative substance, its oxidation to higher valency states can be prevented by the addition of trivalent substances.   The layers may be applied in a conventional way by diode-cathode atomization.

Abstract: Abstract A controller for controlling fluid flow from a source to a motor, such as the steering motor of a motor vehicle.  The controller includes a metering section and a control valve section comprising a stacked assembly of plate valve members which control flow and, along with the metering section, define the outer periphery of the controller, and minimize the need for complex cast housing members.  The controller is compact and yet is constructed to respond to an input signal from an input shaft to direct needed flow from the source to the primary steering motor, and excess flow to an auxiliary motor.  The controller is also characterized by a unique spring centering mechanism which applies a spring centering force to the assembly of plate valve members.  Additionally, the controller is characterized by a special seal arrangement for resisting leakage of high pressure fluid about the input shaft, and by structure for forming pressure dams to resisting leakage of metered fluid.

Abstract: ABSTRACT           The invention relates to a small, efficient hermetic compressor for refrigeration wherein reduction in size and minimization of parts is emphasized.  The motor compressor unit is mounted within a sealed outer housing and comprises a cast crankcase, which is connected to the stator of the electrical motor by means of only three connecting screws that extend through the stator and are threadedly received in sockets in the downwardly depending legs of the crankcase.  The crankshaft is pressed into the motor rotor and is journaled within the crankcase for rotation about a vertical axis.  The compressor unit is resiliently mounted in the housing by means of four mounting spuds, which are press fit over the heads of the aforementioned connecting screws, and a fourth screw extending through the stator, and are resiliently captured within four coil springs connected to the base of the outer housing.  In order to broaden the base of support for the compressor unit, the sockets receiving the heads of the screws are eccentric relative to the respective axes of the fingers of the spuds that are received in the coil springs.  This enables the central axes of the supporting spuds to be radially outward of the connecting screws thereby broadening the base of support and more easily accommodating the field winding end turns.  These spuds also cooperate with upwardly projecting spuds secured to the base of the housing and disposed within the springs to serve as shipping stops relative to vertical movement of the compressor unit.  Semidirect suction is utilized to reduce suction gas superheating for improved efficiency.
