Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for placing a cement thermal packer is disclosed.  The cementing collar of the present invention is assembled into a stream or hot fluid injection string and positioned along the well in the location where the packer is to be placed.  Cement material for the packer is pumped down the injection string preceded by a seperation plug and followed by a sealing plug.  The separation plug seats in the cementing collar to cause the cement to be diverted to the annulus between the well casing and the injection string.  The sealing plug seats in the collar while the placed cement sets to form the packer.  The internals of the collar are sheared from the collar leaving a smooth injection string to the injection zone of the well.

Abstract: PRECAST HOUSE MAKING PLANT                           Abstract In a portable plant for craneless manufacture and erection of concrete wall panels and roof slabs to form single-storey houses, it is known to have two rotatable solid form-erectors, a lifting form and a rotatable plain form-stripper.     This invention represents an improved trailer-mounted hand-operated modification of that plant intended for making houses and shelters consisting of narrow room units (width 2.7-3.6m). In order to overcome some difficulties while building the second and subsequent bays, the form-erectors can be folded lengthwise. The form-stripper is equipped with an additional detachable form for producing and positioning in the same cycle two panels: either an end wall panel and a partition, or two end wall panels (for single-unit bays or shelters). The form-stripper overlaps the form-erectors to provide the proper location of the parti-tions.     The presented modification of the machinery can be used in combination with the previous design of the casting and erecting equipment. Also, the plant may temporarily or permanently operate without the lifting form, while the ceiling and roof are made with traditional methods.     This invention is intended for providing people with low-cost housing, as well as for building annexes and various struc-tures.

Abstract: ABSTRACT OF THE DISCLOSURE.      A pivoting joint connects two rectangular waveguides, connecting transmission-reception equipment on board a satellite to an antenna, which is only opened out when the satellite has been placed in orbit.  These waveguides comprise a fixed section and a moving section, pivoting about the longitudinal axis common to the two sections.  They issue or open out in facing manner on two parallel planar faces separated by a non-zero distance, but which is very small compared with the wavelength.  One of these faces has a quarter wave trap ensuring the radio seal of the joint.  An abutment defines the position in which the two guides are in an extension of one another. When the satellite reaches orbit, antenna is opened out and the joint pivots to this position.

Abstract: DRAG CHAIN CONVEYOR AND CHAIN LINK THEREFORE                  ABSTRACT OF DISCLOSURE          A drag chain conveyor for conveying solid material such as coal, ash,  cement clinker,  cement dust,  ores,  sand,  and gravel,  and other  diverse  materials.   The  conveyor  is  capable  of  being reversible so that material can be fed to the center of a drag chain conveyor utilizing the principles of this invention and conveyed in either direction of travel.  The chain link itself is a modified T-link in the general shape of a cross with one member of the cross acting as the material pusher and the other member of the cross being in the direction of travel of the chain and serving as the chain link.  The chain link member has a lug at one end and a U-shaped enlargement at the other end with the lug of one link being pivotal connected to the U-shaped enlargement of an adjacent link to thereby form the chain.  The U-shaped enlargement has a pair of surfaces each adapted to be selectively engaged by the teeth of an asymmetrical drive sprocket.  When the conveyor is driven in one direction, the drive sprocket engages one face of the link.  When the conveyor is driven in the other direction,  the  drive  sprocket engages  the  other  face  of the chain.  The chain and sprocket are designed so that the chain pivots around the center line of the pin connecting two lengths when engaging the sprocket and disengaging the sprocket.  The sprocket is asymmetrical in configuration to allow for proper chain engagement and disengagement.

Abstract: ABSTRACT   The present invention relates to a ring-like member for use in a glass sheet bending and tempering process most adapted to a process wherein a glass sheet is released from engagement against a vacuum mold of a shape having sharply bent regions about longitudinally spaced, transversely extending lines of relatively sharp bending onto said ring-like member. The vacuum mold has a distance between the sharply bent regions at operat-ing conditions that either equals or is slightly less than the distance desired in the bent glass.  In a preferred embodiment, the ring-like member is split into two shaping rails, which are separable to adjusted positions wherein the sharply bent regions are spaced to conform to the distance desired therebetween in the bent glass sheet.

Abstract: TITLE OF THE INVENTION: OPHTHALMIC PERFORATING INSTRUMENT     ABSTRACT OF THE DISCLOSURE: A surgical instrument for ophthalmic use comprises a rigid elongated outer tubular member which terminates in a closed distal end immediately adjoining a distal side opening. A flexible elongated wire is arranged within the outer tubular member and extends in a direction generally parallel to the longitudinal axis of the outer tubular member. The wire is axially movable within the outer tubular member and has a shape distal end which is positioned in proximity to the distal side opening. The closed distal end of the outer tubular member is provided with an interior curvature which functions as a deflecting member to deflect the distal end of the wire to that the wire projects through the distal side opening at an angle relative to the longitudinal axis of the outer tubular member when the wire is moved axially toward the distal end of the outer tubular member. The wire may be supported by an inner tubular member which is slidable within the outer tubular member and which also functions to conduct an infusion fluid to the instrument tip. Modifications to the basic embodiment include the use of a fixed length of small diameter inner guide tubing as the deflecting member to guide the distal portion of the wire in the direction of the distal side opening in the outer tubular member, and the formation of the wire as a ribbon-like extension of the slidable inner tubular member which serves as the infusion conduit. A surgical method employing the perforating instrument is also disclosed.

To guarantee that during each coupling and disconnecting procedure the absolute sterility of the interior of the female part is maintained the second barrier (11) is mounted in the entrance part of the female part (9) and is pushed entirely through the first barrier (7) during the connection of the connectors (3, 4) into the chamber (8) between the male part (5) and the first barrier (7) before the male part (5) can penetrate the second barrier (11). Further at least the second barrier (11) consists of a resilient material which during the disconnecting procedure of the connectors will be restored in the chamber (8) into the original closing position.
