Title: Box spring assembly with improved spring  installation capability
Inventor: KITCHEN JOHN P
IPC: A47C23/32
Filed: 1980-10-01
Granted: 1983-06-14
Abstract: Abstract of the Disclosure A box spring assembly which includes a generally rectangular frame and a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads.  Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having a lower column section consisting of a straight length of spring wire and an upper section con-sisting of a plurality of substantially horizontal torsion bars and a plurality of angularly arranged connecting bars connected to and extending between the torsion bars so that in response to a downwardly directed bedding load, the upper section will yieldably collapse to accommodate the load and impart a feeling of soft support to the bedding user.  The straight wire column is inclined inwardly so that it can bend lightly and cause a twisting of the tor-sion bar on which it is mounted.  This action imparts a feeling of firm support to the bedding user.  This combina-tion of initial softness and subsequent firmness is desirable in bedding foundations for purposes of user comfort.  In addition, the arrangement of parts facilitates manipulation of stapling tools to secure the mounting torsion bars to the frame.

Abstract: APPARATUS AND METHOD FOR MEDIUM CONSISTENCY OXYGEN DELIGNIFICATION OF PULP                 Abstract of the Disclosure Medium consistency oxygen delignification of pulp is carried out in a series of tubular reaction zones.  Rapid delignification is achieved by agitating the pulp by rotating a timing screw in the first reaction zone at a speed in excess of 10 rpm, modifying the flights on the timing screw to increase the amount of agitation, or a combination of the two.  Primary oxygenation is carried out in the first reaction zone while subsequent zones provide the retention time needed for the delignification reaction to go to completion.  A thick stock pump is used to introduce the pulp into the first reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus for feeding mats to a press, e.g. for the production of particleboard or the like, comprises a feed con-veyor with a discharge nose which lies in a tangent to the plane of a receiving conveyor entraining the mat into the press.  Between the pick-up side of the receiving conveyor and the discharge end of the feed conveyor, this plane is tangent mat with a head bar disposed ahead of the leading edge of the mat.  The surface of the conveyor is provided with recesses to receive each bar so that the latter lies at least in part inwardly of the circumference or peri-phery of the drum while an underlay sheet lies along a drum surface which progressively merges with the circumference from this recess, i.e. is progressively asymptotic.  When the recess is fixed, it can have a flank ahead of the bar against which the bar is positioned.  When the surface is swingable to lift this bar out of the recess, the bar may be magnetically held on the movable portion defining the surface.

Title: Aqueous bleach compositions
Inventor: SMITH EILEEN
IPC: C11D7/54
Filed: 1981-03-18
Granted: 1983-11-08
Abstract: - 1 - GC109 ASTRACT Aqueous Bleach Compositions The present invention relates to aqueous alkaline bleach compositions containing hydrogen peroxide. Under alkaline conditions, it is particularly difficult to prevent the hydrogen peroxide decomposing excessively rapidly during storage, but the addition of an alkaline additive minimises any change in the pH of washing solutions obtained by dissolution of generally bleach free washing compositions containing anionic surfactants. Hydrogen peroxide-containing aqueous alkaline bleach having acceptable peroxide stability can be obtained by employing an alcohol, preferably ethanol, in conjunction with a phosphonate, especially ethylene (diamino tetramethylene phosphonate,) particularly with a polyhydroxy carboxylate, preferably gluconate, or an amino acetate. The liquid bleach can contain a small proportion of a surfactant.
