Abstract: 695,437. Agricultural implements. HUEBNER, H. A., and WORREL, R. M. Feb. 20, 1952, No. 4477/52. Class 6(iii) Side-delivery rakes having rotary raking wheels 37 arranged in echelon and angularly disposed to the direction of travel are mounted on the forward side of a beam 10. To the rear the beam is supported on a ground wheel 11 the plane of rotation of which is angularly adjustable, and on a caster-wheel 12. Forwardly arched bars 23, 24 of unequal length extend from the beam 10 and converge for connection to a clevis 26 pivoted to a toolbar 28 extending laterally from a tractor. Crop-crushing prior to raking is thus avoided. The raking wheels are mounted on cranks 33, 36 the axles of which turn in bearings 32 secured to the underside of the beam 10. For counterbalancing each wheel a vertical bar 50 mounted on the crank-hub is attached to a spring 56 joined to a chain 57. Downward pressure of the wheel may be varied by catching a different link of the chain 57 in a hooked bracket 54. By removing the rakes, supporting wheels and other fitments and disconnecting' the bars, 23, 24 from the beam 10, the beam may be inverted and the parts remounted for collection on the other side. Two beams, each with a set of reversely set rakes may be attached to opposite ends of a tool-bar for collecting a windrow on each side of the assembly. Reference. has been. directed by the Comptroller to Specification 680,537.

Title: Improvements relating to processes and apparatus for the production of foams
IPC: C08J9/00
Filed: 1958-02-20
Abstract: <PICT:0872851/IV (a)/1> A foam is formed by mixing an amino synthetic resin solution with a foaming agent such as a sulphonate of a fatty alcohol and with compressed air in a chamber 1.  The coarse foam obtained is then converted into fine foam by passing it through a tube, the length of which is more than 100 times its diameter. Finely dispersed substances, which may be mixed with the resin foam, comprise plaster of Paris, preferably in the form of a paste, polystyrene, polyurethane, polyvinylchloride, polyvinyl acetate, phenol formaldehyde resins, polyamides, butadiene rubber dispersions, alginates, cellulose and bitumen.  The coarse foam formed in chamber 1 passes into an expansion chamber 8, whence it flows through a coiled tube 10 into a second mixing chamber 11 maintained at atmospheric pressure.  A hardening agent is introduced into chamber 11 through a pipe 12, and mixed with the foam by a stirring device 14 mounted on the same shaft as stirring rods 4 in chamber 1.  In an example, to an aqueous resin solution of a water-soluble reactive urea resin is added an alcohol sulphonate and after conversion into coarse foam, the mixture is passed through the expansion chamber and tube.  A cold hardener comprising 10% phosphoric acid and 2% urea is then added.
