Abstract: ABSTRACT OF THE DISCLOSURE         A continuous sheeting machine is formed with a sheet collection area for the accumulation and stacking of sheets into either ream or skid loads.  Separate lift table and discharge means are provided for the respective ream  collection or skid loading operations. Changeover between skid loading and ream collection is automatic.  A ream collection system is stowed in a retracted position beneath the discharge area of the sheeting machine during skid loading.  In the skid loading mode, two large scissor-lift tables shuttle concurrently respectively back and forth between the collection area and a discharge station, such that skid load collection is substantially continuous.  For ream collection, the skid load tables are removed from the collection area and a ream collection framework is shuttled out from beneath the sheeting machine so that a small, high-speed ream lift table is positioned in the collection area.  As the ream collection table is passed into the collection area, a skid guard is pivotally moved between its former upstanding, operational position beneath a kick-off assembly in the sheeting machine discharge area to a lowered, stowed position beneath the ream lift table.

After a film of fusible plastic has been applied on the decorative layer the laminate is hot press-ed and then immediately cooled in a cold press. The tile obtained has a pleasing appearance because the granules of the base layer have been forced up, in the hot press-1a ing operation, into the holes and recesses of the de-corative layer, filling out these holes and recesses.          In this embodiment the tile has a smooth wear resisting layer surface but this surface can be provided with a relief pattern such that it conforms to the structure of the decorative layer, if the tile after cooling is heated in a free state, i.e. without press plates.   1b

Abstract: Abstract For sealing between an inner part and an outer part which are generally concentrically related so as to have an annulus between them, an elastomeric sealing annulus is axially sandwiched between two beveled anti-extrusion rings, each of which has a deflectable lip. There is a first running clearance radially between this assembly and the bore of the outer part, and a second running clearance between this assembly and the outer peri-pheral surface of the inner part.  When the two parts and the sealing assembly all reach their intended relative positions the seal is established by axially compressing the assembly sufficiently to significantly de-bevel both of the anti-extrusion rings, deflect their lips into contact with one of the parts while urging their opposite edges into contact with the other of the parts.  As the elastomeric sealing annulus is axially compressed it expands radially inwards and outwards into resilient sealing engagement with the two parts.

Abstract: Abstract of the Disclosure The present invention provides a band filter press having a machine frame with horizontal longitudinal beams and sub-beams located there beneath.  The filter cake which is deposited between two endless rotating bands is passed through a press zone having press rolls.  At least two sequential press rolls are arranged on the upper side and/or on the lower side of the longitudinal beam.  This means that the length of the press zone can be restricted to 1/3 - 1/2 of the total length of the press so that the filter cake remover can be arranged in the central area of the press, preferably on the lower side of the longitudinal beam.  This arrangement means that the pre-treatment stage can be defined over the whole length of the press and means that its height can be kept at a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE          According to the invention it is possible to produce both kraft pulp and alcohol from hardwood chips or the like.  The chips are subjected to mild acid prehydrolysis following by mild caustic pre-extraction.  The withdrawn hydrolysate has insufficient furfural to inhibit microorganism growth, and both the hexose and pentose sugars in the hydrolysate are fermented to ultimately produce ethanol, butanol, or the like.  The chips - after caustic pre-extraction - are subjected to a sulphate cook, and wash, and the resultant pulp is kraft pulp and even has viscosity and tear strength charac-teristics more desirable than that of conventional kraft pulp   The pulp can be subjected to oxygen delignification, and achieve a higher K number in fewer subsequent bleaching stages than conventional kraft pulp.

Abstract: DUAL HEAD GAUGER APPARATUS WITH AUTOMATIC     ADJUSTMENT FOR PRESSURE VARIATION                              Abstract An apparatus for testing containers, such as beverage bottles which will be capped or otherwise closed by a vacuum seal, and for rejecting those containers which do not meet the requirements of a container which can be ef-fectively sealed by a cap or other closure.  Containers to be tested move on a conveyor to a test station where the container opening is covered by a test fixture having a nozzle surrounded by a sealing disphragm.  A metered volume of air is injected into the container through the nozzle, and the retention of pressure in the container is sensed.          A defect in the sealing surface is detected by an unac-ceptably rapid leakage of air past the diaphragm, and the defective container is ejected from the conveyor.  The apparatus also tests the internal dimensions of the con-tainer opening by projecting a gauge into the opening.

Abstract: Abstract An apparatus for assembling sheet material assemblages, particularly newspapers, which have a jacket and a plurality of inserts within the jacket are disclosed.  The apparatus includes a circular array of stations and a rotor carrying a plurality of pockets which move below the stations.  A two-speed transmission is provided so that the rotor can be driven at either of two speeds.  At each station there is a hopper for feeding a jacket or insert into the pockets as they move below.  The jacket feeding stations are grouped into a group of two or more adjacent stations. The insert feeding stations are likewise grouped into groups of adjacent stations having two or more in each group.  All groups having the same number of stations and the stations in each group all feed an identical jacket or insert.  In addition there is a single opener station for opening jackets before inserts are fed into the jackets and a single delivery station for each group of jacket feeding stations.  In one embodiment each group includes two stations.  There is a single opener station and a single delivery station.  The rotor is provided with a plurality of groups of pockets.  In operation, each jacket feeding station feeds into a corresponding one of each group of pockets.  Thereafter, each jacket is opened at the single opening station and each insert feeding hopper feeds an insert into a corresponding one of each group of pockets.  In the embodiment where each group of stations consists of two adjacent stations, the jacket feeding stations feed into alternate pockets and likewise each insert feeding station feeds into alternate pockets.  It is also possible to operate the machine so that each station feeds a different insert.          In this case, the rotor moves the pockets more slowly past the insert feeding stations and each insert feeding station feeds a different insert into each pocket as it moves by.  Also, embodiments are disclosed having two or more groups of jacket feeding stations, two or more openers and two or more delivery stations.

Abstract: ABSTRACT OF THE DISCLOSURE        A thin electric wire is wound as a coil around a core through a small-diameter hole defined therein.  The wire is threaded through the hole on an air stream flowing through the hole under a vacuum generated.  Since the wire is drawn into the hole by the air flow, the wire is not required to be positioned correctly with respect to the core hole.          After the wire has been inserted through the core hole, the wire enters a suction pipe and is wound around the core by turning movement of the suction pipe.  When the wire is to be threaded through the core hole again, the distal end of the wire is positioned and cut off.  A cut end of the wire is positioned substantially centrally of the core hole.          Thereafter, a vacuum is developed again in the suction pipe to draw the wire through the core hole.  The wire is thus wound around the core in as many coil turns as desired.
