Abstract: IMPROVED MONOLITHIC CRYSTAL FILTER          Abstract of the Disclosure An improved monolithic crystal filter is disclosed. The filter has input and output ports formed from par-ticular combinations of first, second and third terminals, the latter terminals having been adapted to be connected to certain preselected electrodes of the two adjacent resonators comprising the filter.  More specifically, the first terminal is adapted to be connected to one of the electrodes of a first one of the aforesaid two resonators, the second terminal to the other electrode of the first resonator and to one of the electrodes of the second of the two resonators, and the third terminal to the remaining electrode of the second resonator.  With the first, second and third terminals so adapted, the employment of the first and third terminals as one/of the input and output ports of the filter and the employment of any other combination of two of the terminals as the other one of the input and output ports thereof results in a filter which is found to exhibit two finite frequency attenuation poles whose locations can be varied by varying the filter parameters.  As a result, by proper selection of such filter parameters, the attenuation poles of the filter can be made to bracket the filter passband, thereby causing the filter attenuation characteristic to steeply rise near the edges of such band.

Abstract: ABSTRACT OF THE DISCLOSURE       The service and emergency braking system is disclosed for use on articulated vehicles having service brakes actuated by air pressure and having emergency brakes held in a released condition by air pressure.  The system includes valving which is responsive to a pressure differential be-tween the fluid pressure level in the service line connecting the portions of the articulated vehicle and a reference pressure, so that the emergency brake control is vented during a service brake actuation to permit the emergency brakes to effect a brake application when the pressure of the service line drops below the reference pressure by a predetermined amount, thereby providing braking on all portions of the vehicle in an emergency braking situation when the service brake line interconnecting the portions of the vehicle has been broken or has been left disconnected.  The refer-ence pressure is generally at the outlet of a regulating valve having an inlet connected to the outlet of the conventional operator-actuated service brake control valve.  The regulating valve is provided with valve members between the inlet and outlet thereof which delays fluid communication until the pressure at the inlet attains a predetermined level whereupon the valve opens to permit communication between the inlet and outlet through a flow restricting orifice.  Upon release of the brakes, the regulating valve opens to permit substantially uninhibited fluid communication between the inlet and the outlet.

Abstract: ABSTRACT OF THE DISCLOSURE     Threads are provided for a fastener of a type having an opening in one member with internal helically-shaped threads comprising a plurality of convolutions about the inner periphery thereof, the threads having a crest and a root portion, the threads being formed about a longitudinal axis, and another member having helical threads comprising a plurality of convolutions about the outer periphery thereof, the threads having a crest and a root portion, the threads being formed about a longitudinal axis.  The cylindrical portion is adapted to be placed in the opening by relative rotation of the two threaded members.  The internal threads of the opening and the external threads of the cylindrical portion are substantially identical except that one of the thread formations has a first helix angle which, in an unstressed condition, is substantially constant throughout at least one thread convolution and that the other of the thread formations has a helix angle which, in an unstressed condition, is substantially constant throughout at least one thread convolution but which differs from the first helix angle by a magnitude of 39 to 85 percent of the first helix angle.  As used herein, the helix angle is defined as the angle between a straight line projecting substantially along a portion of the crest of a respective thread formation and a plane which is perpendicular to the longitudinal axis.  This thereby causes a higher prevailing torque for the purpose of impeding relative movement of the threaded members when the threads are engaged.  This invention is therefore particularly useful for the construction of what is commonly referred to as lock nuts by a simple procedure using equipment which can mass produce the tap.

Abstract: ABSTRACT OF THE DISCLOSURE      Porous laminar pellets of comminuted crystalline poly(ethylene terephthalate) waste film are formed.  The pellets do not contain a binder, but are coherent since the polymer flakes making up the pellets are mechanically interlocked or interwined.  Rapid drying and solid state polymerization rates are achieved, and the pellets have sufficient structural integrity to survive such processes, but may be readily disintegrated upon completion of such processes if so desired.  The pellets are also well adapted for dissolution, such as in glycol monomer for glycolysis, and in molten polymer.

The resilient tube is provided at the end sections of its outer surface with peripheral seals  of which the outer diameter is slightly smaller than the inner diameter of the tube being ins-pected.  Between the seals the resilient tube is provided with a plurality of peripheral ribs regularly spaced from one another and with dovetail cross-section.  A duct connectible to a pres-surized fluid vessel communicates with the outer surface of-the rigid tube, a duct connectible to a vessel containing a pres-surized polymerizable resin communicates with the outer surface of the resilient tube and a duct connectible to a vacuum vessel or to the atmosphere also communicates with the outer surface of the resilient tube.  Also disclosed is a method whereby a replica is made by flowing a silicone resin into the space between the tube being inspected and the outside of the apparatus.  After polymerization, the resilient tube contracts and while contracting draws the replica therewith. Thus between the tube being copied and the replica a clearance is formed great enough for permitting the withdrawal of the apparatus from the tube along with the replica of the latter.

Abstract: In conventional procedures for the preparation of phosphorus-vanadium-oxygen catalysts, with or without promoting elements or carriers, the phosphorus compounds and vanadium compounds are mixed under conditions to form precursors.  These precursors are then heated to temperatures up to 600°C. to form phosphorus-vanadium-oxygen catalsyts suitable for the conversion of saturated hydrocarbons, such as butane, to maleic anhydride. According to this invention, a preheat step (60-120°C.) is introduced for a period of time sufficient to form an intermediate prior to the above described heat step, according to which a new phosphorus-vanadium-oxygen compos-ition is formed which is converted to the precursor. Catalysts formed by the process of the present invention, when used for the conversion of saturated hydrocarbons to maleic anhydride, provide higher yields of maleic anhydride.
