Abstract: ABSTRACT OF THE DISCLOSURE         A method for recovering methyl methacrylate from a mixture of polymeric materials containing poly (methyl meth-acrylate) which comprises contacting the mixture with a boiling C5 - C8 alkane, separating an insoluble residue containing poly (methyl methacrylate) from the alkane and its extract, extract-ing poly (methyl methacrylate) from such insoluble residue with boiling acetone, separating the poly (methyl methacrylate) from the acetone, and recovering the methyl methacrylate monomer from such poly (methyl methacrylate) by pyrolysis.  In a pre-ferred embodiment, the poly (methyl methacrylate) containing solid obtained after the acetone extraction is compressed under elevated temperatures and pressures prior to pyrolysis.  The method can be stopped prior to the pyrolysis step when it is desired to recover  only the poly (methyl methacrylate).

Abstract: ABSTRACT OF THE DISCLOSURE           The accuracy of axial alignment of rotary shafts which are connected to each other by face gears is determined by micro-meter screws which are moved into contact with annular control sur-faces of the shafts.  The control surfaces are normal to the axes of the respective shafts and, if their planes are not exactly par-allel to each other, selected teeth of the mating face gears are elastically deformed to a greater or lesser extend to thereby tilt at least one of the shafts with respect to the other shaft until the two axis are acurately aligned with each other.  The elastic deformation of selected gear teeth can be effected by bolts and nuts which connect the two shafts and extend in parallelism with their axes or by a composite annular clamp whose arcuate sections engage tapering surfaces on the flanges of the shafts and are held together by bolts which can tilt the shafts relative to each other by chang-ing the width of gaps between neighboring sections.

Abstract: ABSTRACT     Mechanical coin sorting is known but it is slow and expensive,  Also known are coin identifying devices using staggered photoelectric cells which respond to coins of different diameters but they are only suitable for de-tecting coins having comparatively large differences in diameter.  Disclosed herein is an apparatus for identifying and counting coins which obviates these disadvantages.  The apparatus comprises an optical signal transmitter controlling a counter.  The signal transmitter is forward by an optico-electronic image converter past which the coins are guided and which supp-lies signals analogous to the respective coin surfaces,  The signals are fed to a comparator which, in turn, feeds at least one counter with signals associated with the coins,

Title: Cushioning dunnage mechanism, transfer cart therefor, and method

Abstract: CUSHIONING DUNNAGE MECHANISM, TRANSFER CART THEREFOR, AND METHOD A cushioning dunnage producing mechanism which is of relatively compact nature utilizing a single multi-ply roll of sheet-like stock material, such as paper, which is directed through a separating mechanism.  As the stock is pulled off the composite roll, the edges are rolled inwardly in a longitudinally convergent chute, into generally superimposed condition.  Pusher means urges the sheet-like stock material laterally toward a confronting surface of the chute.  Then the inwardly rolled webs of stock are passed into a crumpler section where mechanism such as meshed gears attach together the confronting portions of the rolled edges of the stock material generally centrally, in a direction lengthwise thereof, to retain the dunnage product in highly compressible, lightweight pad-like form.  A transfer vehicle is adapted to coact with the dunnage producing mechanism for storing a preselected amount of the pad-like dunnage product on the vehicle, whereupon the vehicle can be moved to a location distant from the dunnage producing mechanism for use at the distant location.  A novel method of producing and transferring the pad-like dunnage is disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         A television receiver includes a conventional tri-color cathode ray tube display system having horizontal and vertical scansion systems.  Conventional signal receiving and processing circuitry recovers picture, sound and scansion synchronizing information.  A high voltage shutdown circuit is responsive to excesses of either high voltage or CRT beam current. The former being detected by a resistance divider coupled between high voltage and ground while the latter is sensed by a resistor placed in series with the secondary winding of the horizontal deflection transformer.  A PNP, NPN transistor pair configured to form a switch analogous to a silicon controlled rectifier responds to detected excesses of beam current or high voltage and loads down the operating supply to the horizontal scansion oscillator to terminate high voltage generation.  The transistor pair accommodates a degenerating network to reject false triggering.

Abstract: RECOVERY OF COPPER ABSTRACT OF THE DISCLOSURE Copper is recovered from ores containing sulfuric copper miner-als by forming the ore into a dump leach heap, and substantially saturating (i.c. thoroughly wetting) the ore in the heap with an aqueous strong acid solu-tion containing 100 to 400 g/l H2SO4 and 5 to 50 g/l ferric ion. The ore thus saturated is cured in contact with the strong acid solution for curing period of at least two days, and generally from 5 days to six months or even longer, depending on the character of the ore and its permeability by the acid solu-tion. The ore in the heap may be run of mine size, or may be coarsely crushed, again depending on permeability to the strong acid solution. After the curing period, the ore in the heap is washed by percolating through it a weak acid solution containing up to 50 g/l H2SO4 and 5 to 50 g/l ferric ion. The wash solutions are collected and treated for copper recovery. Washing is continued until the copper content of the heap has been largely extracted.
