Abstract: ABSTRACT OF THE DISCLOSURE     An inflatable escape slide deployable to provide an inclined descent path for evacuees comprises first and second inflatable slide sections arranged side-by-side, each slide section having a slideway and the two slideways being separated by an inflatable centre wall.  Flexible baffle means extend through-out the length of the centre wall and subdivide the centre wall internally into non-communicating first and second compartments or series of compartments, the first compartment or series of compartments forming part of and being inflatable with the first slide section and the second compartment or series of compartments forming part of and being inflatable with the second slide section.  Inlets are provided for inflation of each slide section independently of the inflation of the other slide section.  Upon loss or absence of inflation of one slide section the flexible baffle means distends under inflation of the other slide section or can be made to distend by additional inflation of the other slide section to compensate for the absence or loss of inflation of the centre wall compartment or series of compartments of the uninflated or under-inflated slide section.

Abstract: SPRING WIRE BLADES FOR DRUM TYPE MOWERS            ABSTRACT OF THE INVENTION      "L" shaped spring wire blades for use on drum type mowers. The upper ends of the vertical leg por-tions of the L-shaped members are fastened to the drum near its upper end and arcuately spaced apart around its cylindrical surface.  The vertical portion of each blade projects downwardly at a position closely adja-cent the outer cylindrical surface of the drum and pas-ses through an opening in the disc at the base of the drum whereafter the horizontal portion of each blade ex-tends radially outwardly beneath the disc.  A hay cut-ting end of each blade projects radially outwardly beyond the disc to effect cutting of hay as the drum and its uni-tary disc rotate.  The spring wire blade can yield rear-wardly about its vertical leg as an axis of torsional twist when its horizontal leg strikes an obstruction.  The inherent spring nature of the L-shaped blade will cause it to automatically resume its cutting position when the obstruction is cleared.  The mower preferably uses drums in pairs which rotate inwardly toward each other to ef-fect more efficient cutting and to simultaneously windrow the cut hay.  Paddle elements are affixed to the outer cylindrical surface of the drum at positions closely in front of the vertical leg of each L-shaped wire blade to aid in the delivery of the harvested hay rearwardly in a windrow and to prevent any cut hay from wedging between the wire blade and the outer surface of the drum.

Abstract: DAMPED APPARATUS FOR QUICK-STOPPING ROTATING MEMBERS    ABSTRACT OF THE DISCLOSURE         Quick or instantaneous stopping of rapidly rotating members places severe stress loads on components.  These loads are substantially reduced by providing a quick-stopping apparatus including a damped member having an attached element which is movable into engagement with a rotating member. In response to such engagement, the energy of the rotating member is rapidly decelerated through the damped member thus reducing peak stress loads associated with almost instantaneous deceleration.

Abstract: ABSTRACT     A fluid shear coupling apparatus is disclosed herein which includes a driving member received within a working chamber defined by a driven member.  The driven member is mounted with needle bearings to a shaft portion of the driving member to have the members rotatable about a common axis.  The driving and driven members include complementary shaped and positioned fluid shear and thrust surfaces defining fluid shear and thrust chambers, respectively, therebetween and cooperable with shear fluid within the chamber to transmit torque and axial thrust loads between the members.  The fluid shear surfaces are defined by interdigitated ridges and grooves.  A shear fluid reservoir is located in the central portion of the driven member and passageways lead from an annular groove and cylindrical cavity adjacent the driving member back to the reservoir.  A recycle passageway also leading from the annular groove and connects with the working chamber at a radially-inward location to provide recirculation of shear fluid through the working chamber.  Several projections and dams are received within the cylindrical cavity and annular groove to provide shear surfaces for transmitting torque between the driving and driven members, and also to facilitate the pumping of the shear fluid from the working chamber back to the reservoir or through the recycle flow path.

Abstract: Abstract of the Disclosure. An anion exchanger is produced by treating cellulose or a cellulose derivative with a polyethylene imine solution of at least 1% by weight in an aqueous medium at a pH-value between 2 and 6, preferab-ly between 4 and 5, and recovering the ion exchanger from the re-action mixture. The reaction between cellulose or cellulose derivative and polyethylene imine can take place at ambient temperature, but may be promoted by using a temperature of 40-90° C, preferably 60-70°C. Preferred cellulose derivatives for use as starting material are sul-phonated lignocellulose or a cellulose material, e.g. bark which has been treated in separate steps with an alkali hydroxide solution and with sulphuric acid. The anion exchanger can be regenerated by el?-tion with sodium hydroxide and reactivated by treatment with poly-ethylene imine. The anion exchanger is suitable for the purification of waste water and can be produced at low cost.

Abstract: Abstract of the Disclosure Disclosed is a process for microencapsulating a core material and subsequently releasing the core material by selectively disrupting the membranes of the microcapsules.  The encapsulation technique involves the formation of a semipermeable membrane, e.g., around a droplet, through the formation of multiple ionic salt bonds between a polyionic polymer in the droplet and a crosslinking polyionic polymer which possesses multiple ionic groups of opposite charge.  The membrane can be selectively disrupted by exposing it first to a solution of com-peting crosslinking multivalent (preferably di or trivalent) ions followed by a solution of a competing polyionic polymer of the same charge as the polymer in the original droplet.          Alternatively, a mixed solution of the two competing solutions may be used together.  For example, a membrane comprising anionic alginate salt bonded to cationic protein can be selectively disrupted by exposing the membrane to a mixed solution of mona-tomc, multivalent cations, e.g. Ca++ ions, and a water-scluble polymer have plural anionic moieties, e.g., heparin, and sub-sequently sequestering the monatomic cations.     The process may be used to encapsulate and subsequently release cell cultures without damage to the cells.

Abstract: ABSTRACT OF THE DISCLOSURE An explosion-proof battery vent and filler plug (10) is disclosed, which provides a flame barrier (16) to prevent external ignition of gas evolved from a battery during operation from causing ignition of the larger volume of gas within the battery itself, without simultaneously allowing a high rate of evaporation of the electrolyte. In accordance with the invention, the flame barrier means (16) is provided with an indirect, restricted outlet (64) for the evolved gases to pass to the atmosphere, thus reducing the flow of air through the electrolyte space of the battery.  The preferred embodiment includes a filler tube (14) with a funnel-shaped entrance (24) within a shell member (12) which sealingly engages an opening of a battery   Gas evolved from the battery during operation passes into a splash chamber, (46) then through a baffle (18) into an expansion chamber 52, and then flows through a microporous disk flame barrier (16) into an exit chamber, (65), and vents to the atmosphere through vent holes (64) which are substantially smaller than any previous passage through which the gas has passed, thus forming an indirect, a restricted outlet for battery gases, and a restricted inlet for air flow to limit the rate of evaporation of electrolyte.
