Title: Sculling device
IPC: B63H16/06
Filed: 1973-03-06
Abstract: 1430132 Sculling devices C CORNELL 6 March 1973 10770/73 Heading B7V An oar 26 is pivoted by a bolt 7 to a support 1 for movement between two positions which are defined by stops 27 and 28 and which give opposite angles of attack of the blade. The support 1 is itself pivoted by a shaft 9 in a support 3 secured to the boat 3. Thus, by oscillating the oar handle in an arc about the shaft 9, the oar position is alternated between its stops to give a sculling action. The action of the oar can be reversed by lifting sleeves 19 and 20, along with the oar, from pillars 15 and 16 and replacing the sleeves after inversion. The rowlock is so mounted on the boat that it can be swung inboard. In a modification, Figs. 5-9 (not shown), the oar cannot be remounted to give a reverse action, but the oar may be provided with a second handle which lies parallel to the normal handle but on the opposite side of the bolt 7. Operating the second handle thus gives an action which is the reverse of that obtained by using the normal handle.

Patent GB-1035844-A (GB)
Title: Producing artificial filaments and films from condensation polymers
IPC: D01F6/72
Filed: 1963-03-20
Abstract: Artificial filaments or films are produced by extruding into an aqueous acid coagulating liquid a solution made by dissolving in sulphuric acid having an initial concentration of at least 95% by weight a condensation polymer containing in the molecule repeating =NCO-groups and a salt which is capable of dissociation in the acid into cations and anions having an affinity for protons at least equal to that of bisulphate ions. The polymer may be polyhexamethylene terephalamide and the coagulant may be aqueous sulphuric acid of 40 to 60% by weight concentration maintained at a temperature within the range 30 DEG  to 60 DEG  C. inclusive.  The salt may be an ammonium or alkali metal sulphate, benzoate or acetate, or disodium or diammonium phosphate.  The polymer may be a polyamide proper, such as a nylon, a polyurethane or a polyurea.  The process is particularly suitable for the production of crimped filaments of condensation polymers whose melting points are too high to render them suitable for melt spinning, e.g. polyamides melting above 275 DEG  C., and polymers having cyclic groups, for example, meta- or paraphenylene, cycloalkylene groups such as 1,4-cyclohexylene and for heterocyclic groups such as piperazylene or 2,5-dimethyl piperazylene, as in integral part of the polymer chain.  A long list is given of condensation polymers which may be used.  The sulphuric acid used for dissolving the polymer and the salt is preferably of 95 to 100% by weight concentration. Fuming sulphuric acid, e.g. sulphuric acid containing up to 6 or 7% or even more of free sulphur trioxide may also be used.  The spining solution may contain 5 to 30% by weight of the polymer.  The proportion of salt dissolved in the sulphuric acid solvent is preferably 5 to 8% based on the weight of the solvent. The liquid coagulant may be aqueous formic acid of 52 to 68% by weight concentration or aqueous acetic acid of 52 to 63% by weight concentration, these coagulants being maintained at temperatures of for example, about 20 DEG  to 55 DEG  C.
