Title: Method and apparatus for receiving folded printed products from printing machines or the like
Inventor: REIST WALTER
IPC: B65H29/66
Filed: 1987-10-21
Granted: 1991-08-20
Abstract: INVENTION:  METHOD AND APPARATUS FOR RECEIVING FOLDED PRINTED             PRODUCTS FROM PRINTING MACHINES OR THE LIKE   ABSTRACT OF THE DISCLOSURE     A conveyor device which is equipped with grippers secured to a chain structure is arranged beneath a rotary bucket or fan wheel of a printing machine, typically a printing press.  These grippers engage trailing edges of the printed products which still abut against at least one stripper wheel.          The printed products are thus fixedly retained before departing from the rotary bucket or fan wheel.  By means of a revolvingly driven belt, which engages at the trailing edges of the printed products, these printed products are displaced or stuffed into the associated compartment or bucket of the rotary bucket or fan wheel prior to their engagement by the grippers.  The printed products thus assume a defined position within the compartments or buckets, thus rendering possible the subsequent positionally-correct removal of the printed products from the compartments or buckets of the rotary bucket or fan wheel.

Title: Locking mechanism for trailer coupling
Inventor: BLACKLAW WILLIAM
IPC: B60D1/04
Filed: 1987-11-03
Granted: 1991-10-15
Abstract: Abstract of the Disclosure The lockng mechanism of the present invention is comprised of a pawl which is rotatable to a locking position, where it contacts the latch which covers the pintle that carries the trailer drawbar.  The pawl has a central cavity which contains a pair of rotatably mounted prongs that normally extend outwardly from the sides of the pawl but which can be placed into the cavity when manually deflected.  When the pawl is in its locking position, against the latch, the prongs extend into notches in the side walls of the body of the coupling and thereby prevent the pawl from being lifted off of the latch.  A cam, which is rotatably mounted on the bolt which journals the pawl, has paired plates which fit behind the prongs and prevent them from being deflected into the cavity.  Thus, before the prongs can be deflected and thereafter the pawl lifted to unlock the latch, the cam must be rotated to a position where its faces are moved away from the prongs.

Title: Filtering device for thermoplastic material
Inventor: FOGARTY JOHN E JR
IPC: B29C48/692
Filed: 1988-02-16
Granted: 1992-04-21
Abstract: 1288 ABSTRACT OF THE DISCLOSURE A filtering device for filtering a thermo-plastic material by passing a continuous filter across a passage through which the material is caused to flow at an elevated temperature and pressure. The filter is passed through entry and exit ports flanking the passage. Seals on the filter cooperate in sealing engagement with the walls of the entry port to prevent the flowable thermoplastic material from escaping therethrough. The exit port is larger than the entry port, and is sealed off by a solidified plug of the thermoplastic material bonded to the filter. The pressure of the thermoplastic material in the filter passage forces the plug out of the exit port into contact with an external stop, with that portion of the plug in contact with the stop being selectively heated to accommodate controlled emergence of the plug and the filter bonded thereto. 36-1T

Abstract: ABSTRACT OF THE DISCLOSURE           A  pulley  assembly  for  lifting  loads  in gradients. including: a  main frame  adapted to  be mounted  to an overlying horizontal part  of a ground supported structure.  A first pulley is journalled to the main frame and is engaged by  a first cable, the first  cable defining  a trailing  section adapted to carry a load to be lifted  at  one  end  thereof.    A  second  pulley is journalled to the main frame and is engaged by a second cable.  A lever arm pivoted to the main frame locks the first cable against rotation  about  the  first  pulley.   The second cable defines a trailing section, fixedly secured  to the  lever arm,  and a lead section, extending downwardly to a pulley assembly operator.  The lever arm biases two disks, which are mounted to the  main frame, toward each  other.   Since the  lead section  of the first cable passes between these two disks, this  cable cannot  freely rotate around its pulley in normal conditions because it is frictionally taken in sandwich between the two disks.   The lever  arm carries also a  Y-shaped bracket  engaging the  lead section of the first cable, so that upon the ground operator pulling the bottom end of the second cable lead section, the two disks will move apart from each other, enabling progressive lifting of  the load  at the end of the trailing section of the first cable.

Abstract: A process for separation of hafnium tetrachloride from zirconium tetrachloride is disclosed. Zirconium tetrachloride containing hafnium tetrachloride in natural ratio dissolved in a molten salt is reduced in the first phase electrolysis to produce zirconium trichloride containing a hafnium content lower than that of the zirconium tetrachloride at a cathode. Next, in the second phase eletrolysis the zirconium tetrachloride under maintenance of an initial concentration thereof is further reduced with another cathode by using as an anode the former cathode on which the zirconium trichloride was produced in order to yield zirconium trichloride of a lower hafnium content at another cathode and at the same time evolve on the anode gaseous zirconium tetrachloride having a high pressure by oxdizing zirconium trichloride produced in the first phase electrolysis.       This evolved zirconium tetrachloride is separated and recovered as zirconium tetrachloride with a low hafnium content. Further, the zirconium tetrachloride with a low hafnium content and the zirconium trichloride with a lower hafnium content are produced by changing over polarities of the cathode and the anode when zirconium trichloride on the anode decreases. Subsequently, the production of zirconium tetrachloride is continued by exchanging polarities of the electrodes and the second phase electrolysis is carried out repeatedly. After hafnium tetrachloride is concentrated to an expected value in the molten salt at above mentioned electrolysis, the salt is transferred to a separate vessel. And then it is heated to evaporate and separate highly concentrated hafnium tetrachloride. Thus, zirconium tetrachloride and hafnium tetrachloride are respectively separated with high efficiency. A hafnium content of zirconium tetrachloride separated is able to reduce to less than 100ppm, and a zirconium content of hafnium tetrachloride separated is also reduced to less than 25wt%.
