Abstract: ADJUSTABLE-GRIP LATCH                          Abstract An adjustable grip latch has a slippable, friction-type drive connection provided between a shaft and a pawl which is carried on the shaft.  A stop extends alongside the shaft for limiting the travel of the pawl to a range of movement extending between latched and unlatched positions.  When the pawl is in its latched position it engages one portion of the stop.  When the pawl is in its unlatched position it engages a different portion of the stop.  The slippable drive connection transmits only a limited amount of torque from the shaft to the pawl,  thereby enabling the shaft to move the pawl between its  latched and unlatched positions, and enabling the shaft to rotate relative to the pawl when the pawl has engaged the stop.  The slippable drive connection utilizes a wave spring washer to effect transmission of limited torque from the shaft to the pawl.

Abstract: ABSTRACT OF THE DISCLOSURE     An automated assembly produces a continuous, contiguous series of individual pieces sewn in a continuously operating sewing machine by conducting successive pieces to the sewing station through a feed station.  The feed station may receive the pieces intermittently and irregularly but is equipped with guides and drives for accelerating each successive piece relative to the preceding pieces being sewn in the sewing machine to overtake any spatial gap between the trail end of the preceding piece and the lead end of the succeeding piece so that these ends abut prior to completion of the sewing of the preceding piece.  The drives are continuously operating, yet overlapping of the end-to-end relation of the pieces and bunching or furling of the pieces due to this end-to-end abutment are prevented by guide surface confinement of the pieces in the feed station and a predetermined capability for slippage in the drive.  The assembly has application in the making of closures for fly openings.

Abstract: Abstract of the Disclosure Tarpaulins  (sometimes  termed "tarps")  are used to protect an underlying structure or material from wind, rain and the other effects of the weather.  Some tarpaulins are insulating in nature. Such insulating tarpaulins in the past have comprised weatherproof membranes with a plastic foam or polyester fiberfill portion between the membranes.   These prior membranes  have been characterized by short  useful  life  and  marginal  insulating  and  weatherproofing ability, either because of limitations of the insulating fill (foam or  fiber)  or  difficulty  in  sealing  the  seams  or  edges  between adjacent tarpaulins.  The disclosed tarpaulin comprises a first and second membrane sandwiching an insulating batt of a highly resilient fibrous glass insulation.  The tarpaulin includes a seam structure around all four edges of the tarpaulin which not only fastens the first and second membranes together but holds the highly resilient fibrous insulating batt in position.  At least two adjacent edges of the tarpaulin include a flap on the weatherside membrane overlying and extending along the seam structure along each of those adjacent edges.  The tarpaulin further includes an indicia on the weatherside membrane for indicating the preferred orientation of the membrane when  in  use,  and  further  includes  a  vent  through  weatherside membrane.   This vent  is  so  constructed to prevent penetration of precipitation,  yet  it  permits  the  tarpaulin  to  be  stored  by compressing  the  fibrous  insulating  batt  and  exhausting  the  air during  this  compression,  as  well  as  permits  reinflation  of  the tarpaulin upon deployment for use.

Abstract: ABSTRACT OF THE DISCLOSURE      A  method  of  preparing  and  handling  a  coment-containing  composition  such  as  concrete  and  mortar broadly  used in civil,  construction and various  other fields  is  disclosed.   To prepare the mortar   or  the like, a hydration reaciton of cement and water is caused in the presence, if necessary, of aggregate such as sand or gravel.   According to the present  invention,  small ice masses are used in lieu of water.   That is, cement, aggregate  and  small ice masses are mixed  and  kneaded together  in a low water-to-cement ratio and in a quasi-solid  state  wetted  by  a  small  quantity  of   water resulting  on the surfaces of the small ice masses  from the  melting thereof into a macroscopically  homogenious system.    Subsequently,  gradual  transition   of  this system  into  a homogenious mixture with the melting  of the  small dice masses is caused.   The ice  masses  are entirely  melted  until the instant of charging  of  the composition thus prepared.

Abstract: HITCH STRUCTURE WITH VARIABLE LINK     Abstract of the Disclosure Three-point hitch structure for connecting an implement to a towing vehicle wherein the upper link is made variable by means of a hydraulic cylinder pinned to a plate to provide three pivot points.  When the cylinder is retracted, the two components act as a fixed length link, with the middle pivot point maintained slightly off center with respect to the two outer pivot points by a stop member.  When the cylinder is extended, the middle pivot moves away from the centerline joining the two outer pivot points to allow the overall length to either lengthen or shorten.  The towed vehicle is therefore free to rock with respect to the hitch and includes gauge and stabilizing wheels to maintain the implement in proper relationship with the ground contour.  The link cylinder is plumbed into the hitch lift circuit so that when the implement is raised to transport position, the upper link automatically becomes fixed length and when the implement is lowered to operating position, the link automatically returns to a variable length configuration.
