Abstract: ABSTRACT          A process for the removal of hydrogen sulfide and ammonia from a vapor stream, and from a dilute aqueous solution containing free and fixed ammonia salts and acid gases comprises scrubbing the vapor stream in a scrubber (202) by contacting the vapor stream with an aqueous ammonia solution to remove the hydrogen sulfide from the vapor stream, subjecting the dilute aqueous solution to a free and fixed ammonia still process (214, 224) passing an overhead vapor stream from the second still (224) through an indirect heat exchanger (226a) to heat the liquid in the first still (214) and then passing the overhead vapor stream to the scrubber (202) for the removal of the hydrogen sulfide.

Abstract: ABSTRACT OF THE DISCLOSURE       A button assembly is disclosed for attachment on a garment fabric, which assembly comprises a female or button part having an apertured shank and a male or fastener part having a pointed shank for insertion into the aperture of the female shank.  The button assembly is provided with means for expelling the air entrapped within the aperture of the female shank which would otherwise cause rupture of the button part.         The advance in the art is in that the invention provides the desired strong connection between the two elements by utiliz-ing virtually the entire volume of the axial cavity for the material of the stem.  At the same time, the invention facilitates the assembling of the button by ensuring that any air that might be entrapped within the cavity is released.

Abstract: Abstract A corrugator for receiving plastic from an extruder and continuously molding corrugated plastic tile therefrom.  The corrugator has a plurality of mold assemblies which are continuously driven to roll about an endless track-way on the corrugator frame, a portion of which defines a molding section.  Each mold assembly includes a pair of mold blocks mounted to pivotally open and close.  As the mold assemblies enter the molding section; the mold blocks thereof pivotally close and come into abutting relationship with the closed mold blocks of preceeding mold assemblies to cooperatively form a corrugated molding tunnel.  Extruded plastic is received by the molding tunnel which moves with and molds the corrugated tile.  At the end of the molding section the mold blocks pivot away from and release the tile.  To augment the formation the tile the mold blocks are cooled.  Additionally a vacuum is induced between the extruded plastic and the wall of the molding tunnel to assure the mating thereof.

Abstract: ABSTRACT OF THE DISCLOSURE     A railway fastening, especially adapted for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge, or like supporting structure, is in the form of a resilient clip having a substantially planar body portion with an opening for a bolt which is offset with respect to the resilient end engaging bridge girder.  The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie.  A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement.  In order to provide greater resilience, the arch can be in the form of two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange.  A projecting lug adjacent to the opening for the bolt is provided to facilitate securing a bolt tensioning member, i.e., a nut.  The clip thus serves as a large washer to firmly hold the cross-tie as well as the girder when the bolt is inserted through the opening and secured with the nut.

Abstract: ABSTRACT OF THE DISCLOSURE A pole switch firing control for a pulse width modulated inverter controls pole switch operation under steady state operating conditions such that the inverter output  duplicates  a  reference  signal  waveform  after  a fixed time delay.  Pole switch operating time for a given pulse in an inverter output cycle is measured and sub-tracted from a fixed time interval to get a delay time. In the succeeding output cycle, the corresponding pulse is produced by initiating the pole switch operating sequence after the delay time, thereby causing the pole switch to operate a fixed time following the reference signal.

Abstract: Method of and devices for the compensation of synchronization errors in the transport of the record carrier in non-impact matrix printers.            ABSTRACT:          In non-impact printers, notably line printers, in which the in-dividual lines of print are formed by the successive printing of pic-ture lines, synchronization errors in the transport of the record carrier have an adverse effect on the printed picture. The invention provides a method for neutralizing such synchronization errors, without influ-encing the transport of the record carrier and without changing the printing frequency of the printing elements. To this end, a control value is derived from the difference between the actual transport speed and the predetermined transport speed of the record carrier. This control value shifts the printing of a picture line in its predetermined printing zone without changing the printing frequency of the picture lines.

Abstract: VEHICULAR STEERING AND SUSPENSION SYSTEM        Abstract of the Disclosure This invention relates to an improved steering and suspension system for use on off-road type vehicles.  The system comprises a gear train at each drive wheel made up of three gears:  an input gear, an intermediate gear and an output gear. The input gear is mounted on a driven output shaft which extends out of the differential of the vehicle.  The output gear is mounted on an outwardly extending shaft which is retained in a gear case which surrounds the entire gear train.  Rotatably attached to this gear case is a tubular hub with a pivotally attached yoke.  The yoke supports the axle on which the drive wheel is mounted.  Positioned within the area defined by the tubular hub and the yoke are intermeshing bevel gears.  These bevel gears unite the outwardly extending shaft with the axle and allow torque to be transmitted from the engine of the vehicle to the drive wheels.  Also included in this system are two pivotally connected arms which unite the tubular hub to the frame of the vehicle.  These two linkage arms cooperate with attached actuating and suspension means to retain the pivot axis of the yoke in an upright position.

Abstract: EGG PRODUCT AND PROCESS                  ABSTRACT OF THE DISCLOSURE      Disclosed  are  a  freeze-thaw stable  egg product and a process  for  preparing  it.   The product comprises  discrete pieces  of  egg,  bound  together  and  covered with a batter coating.  Preferably, the discrete pieces of egg include from about  0.5  to  about  4.0%  of  water-binding  carbohydrates including cold-water-insoluble starch and hydrophilic colloids to  obtain freeze-thaw  stability.   The  use  of  cold-water-insoluble starch, and the addition of the hydrophilic colloids in a blend with a vegetable oil, are helpful in obtaining good mixing without excessive shear.  The egg mixture is cooked, diced and coated with a binder.  Preferably,  the binder is added  in  two  portions,  one dry and one  liquid.   The dry portion preferably employs cold-water-soluble gelatin which provides structural integrity during forming but is liquid at serving temperature,  thereby adding juiciness and enhancing flavor release. The products are batter dipped and preferably breaded,  and are preferably prepared for serving by deep fat frying.
