Title: Improvements in or relating to couplings for railway vehicles
IPC: B61G3/22
Filed: 1922-08-16
Abstract: 204,836. Boonzaier, W. G. Aug. 16, 1922. Couplings, automatic.-An automatic coupling for railway and other vehicles comprises a coupling head having forwardly projecting arms forming between them a buffer recess, one arm constituting a guide member and carrying a toothed pinion adapted to engage a similar pinion on the opposed coupling member, with means, such as a pawl, for holding the pinion in its locking position. Each coupling head 1 comprises a guiding jaw 1<a> and a buffing jaw 1<b> in which is mounted vertically a long pinion 5 the teeth of which are engaged by a ratchet 6. The head 1 is pivotally mounted on a bolt 4 secured by a key in the draw-rod 2 and is centred by a spring 13, fixed to the head of the bolt 4 and engaged between stops on the underside of the coupling head. The ratchet 6 is controlled by a spring 8 or by a weighted lever and is disengaged from the pinion 5 by means of a chain or rope 9 attached to a handle at the side of the vehicle. In a modification the ratchet 6 works on teeth of smaller pitch cut in the centre of the length of the pinion 5 to permit finer adjustment of the coupling when locked. In a further modification, Fig. 8, a hook 20 pivoted at 21 in the coupling head replaces the pinion 5. The hook projects into the jaw of the coupling by means of a spring 22, its forward movement being limited by a stop 23.

Title: High molecular weight thermoplastic polyhydroxypolyethers
IPC: C08G65/28
Filed: 1965-05-26
Abstract: High M.W. polyhydroxypolyether resins having a Durran's melting point >200 DEG  C. are obtained by heating, at a temperature not substantially greater than 175 DEG  C. a normally solid thermoplastic resin containing substantially equivalent ratios of 1,2-epoxy groups and phenolic hydroxyl groups and having a Durran's m.p. of 50-180 DEG C. until the m.p. is >200 DEG  C.  The low M.W. resin is prepared by reacting a diepoxide and a diphenol in the presence of a basic organic catalyst in a ratio of 0.95 to 1.05 phenolic hydroxyl groups to one epoxy group at a temperature below the peak exotherm of the reaction.  The resinous composition may be in the solid form during the heating step, e.g. as particles suspended in a fluid bed or suspended in a non-solvent.  The diepoxide may be the diglycidyl ether of p,p1-dihydroxydiphenylpropane and the diphenol may be bisphenol-A or hydroquinone.  The basic organic catalyst may be a tertiary amine, e.g. of formula <FORM:1101739/C3/1> where R1 is H, alkyl, phenyl, alkyl substituted phenyl, H-N-alkyl, alkyl-N-alkyl or alkyl-N-phenyl, R2 is H, alkyl, phenyl or alkyl substituted phenyl, R3 is alkyl and R4 is H, alkyl or vinyl; n is 3, 4 or 5.  A non-reactive filler may be added to the resinous composition prior to heat ageing, e.g. aluminium powder, particulate polyethylene and other conventional fillers and pigments.
