Abstract: Abstract Magnetically actuated devices such as, e.g., switches and synchronizers typically comprise a magnetically semihard component having a square B-H hysteresis loop and high remanent induction.  Among alloys having such properties are Co-Fe-V, Co-Fe-Nb, and Co-Fe-Ni-Al-Ti alloys which, however, contain undesirably large amounts of cobalt.           According to the invention, devices are equipped with a magnetically semihard, high-remanence Fe-Mn alloy which contains Mn in a preferred amounts in the range of 3-25 weight percent whose remanence Br (gauss) typically is greater than or equal to 20,000-500 ? (weight percent Mn), and whose squareness Br/Bs typically is greater than 0.95.           Magnets made from alloys of the invention may be shaped, e.g., by cold drawing, rolling, bending, or flattening and may be used in devices such as, e.g., electrical contact switches, hysteresis motors, and other magnetically actuated devices.           Preparation of alloys of the invention may be by a treatment of initial deformation, aging, deformation, and final aging.

Abstract: ABSTRACT    Improved linear aromatic polyesters of bisphenols and dicarboxylic compounds are prepared by improved transesterification polymerization processes involving the use of liquid catalysts such as normally solid materials in molten form and normally solid mate-rials in solution in a solvent for the catalyst.  The improved processes comprise introducing a catalyst and liquid state reactants substantially concurrently to the polymerization reaction to avoid substantial heating of the reactants in contact with the catalyst prior to onset of the transesterification reaction.  It is pre-ferred to carry out the transesterification in a fully continuous process or in a semi-continuous process which employs an initial batchwise reaction, followed by continuous reaction using a wiped film reaction vessel.  The products of the processes have un-expectedly low polydispersity.

Abstract: ABSTRACT OF THE DISCLOSURE         A disc brake assembly includes a torque member which carries at least one pin for slidably supporting a caliper.  The one pin threadably engages the torque member and extends on both sides of the disc.  A pair of friction elements are engageable with the disc to retard rotation of the latter.  On one side of the disc the one pin slidably engages the caliper, while on the other side of the disc the one pin slidably engages one of the pair of friction elements.  The one pin is spaced from the caliper on the other side of the disc where the one pin engages one of the pair of friction elements.  The one pin cooperates with a resilient bushing on the caliper to form a sliding connection therebetween and also cooperates with a resilient bushing on the one friction element to form a sliding connection therebetween.  A thermo-plastic  sleeve is disposed between the resilient bushing on the caliper and the one pin, and the sleeve is disposed remote from the torque member so that when the one pin is connected to the torque member, the sleeve remains in an axial unloaded condition.

Abstract: ?.350 ELECTRICAL TERMINAL Abstract of the Disclosure The electrical terminal includes an electrical contact and a resilient, generally U-shaped reinforcing member. The contact includes a strip of metal of flexible material having good electrical conductivity, a low coefficient of friction, and the oxide of which is a relatively good con-ductor.  The contact has at least a portion formed as a generally U-shaped member with a bight portion and having arms more closely spaced at its free ends than in the re-gion of the bight portion.  The arms are flared outwardly at their free ends.  The U-shaped member is formed with a plurality of recesses which extend from the free ends through the bight portion.  The reinforcing member is arranged substantially without the U-shaped member contact and embraces the arms, and is formed of material which re-tains its resiliency when subjected to heat.  The resilient member is formed of a plurality of recess engaging portions connected at ends thereof with the portions being adapted to nest, at least partially, within the recesses.  The re-cesses can be in the form of slots.  The slots or recesses are narrower at their ends than at their bight portions, and the connected strips of the resilient member can be adapted to seat, at least partially, within the slots with the connected strips being wider at their bight portions than at their ends.  The flexible material can be copper alloy, such as copper plated with tin, and the resilient material can be high carbon steel.  Each of the formed arms, which were slotted, form furcated fingers and each pair, preferably, have facing convex surfaces.  In some embodiments, only one of the contact and resilient member has a slot.

Abstract: RCA 74,957A                 Abstract of the Disclosure An I.F. amplifier is provided in which gain control is accomplished by varying the A.C. impedances of variable impedance devices, which devices are coupled as load and emitter degeneration impedances fox amplifying transistors.  Variable D.C. gain control currents are applied to the variable impedance devices to vary their impedance.  Substantially all of the D.C. gain control currents flow through the variable impedance devices in current paths which are separate from the amplifying transistors, thereby avoiding variation of the operating points of the amplifying transistors.  The I.F. amplifier includes a D.C. feedback path which does not require the use of feedback amplification, due to the lack of any changes in the operating points of the amplifying stages during gain control.  Elimination of the need for feedback amplification also prevents the introduction of noise into the amplified I.F. signals.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is the reusable clamping combination of a self torque limiting elastomeric unthreaded member and a screw-threaded member.  Beyond a preselectable screw-induced maximum torque, continued screw-on rotation of said members produces no additional axial relative movement between the members.  The unthreaded member comprises an elastomeric cylindrical screw-thread engaging portion which resiliently deforms when engaged by the peripheral portions of the thread on the threaded member, relative rotation of the members resulting in relative axial travel between them.  The amount of relative axial travel is limited by the combination of resistance forces from an abutment means of the unthreaded member and torque forces produced by the relative rotation between the members.  The abutment means achieves a radial locking of the threads and an axial clamping at the limit of the relative axial travel.

A twin beam type transducer having strain gages at the flex points of the beams is coupled to the shaft supporting the moving web through a self-aligning anti-friction bearing, the strain gages being so located and electrically connected that effects of friction in the bearing due to bending of the shaft are automatically cancelled out in the circuitry in which the strain gages are connected. The self-aligning bearing coupling is arranged to permit relative axial displacement between the shaft and the twin beam transducer for accommodating comparatively large amounts of shaft expansion. The bearing also may have a bearing surface liner comprised of a low coefficient of friction thermoplastic resin material such as * teflon fiber or teflon fiber-filled acetal resin fabric. *TRADEMARK
