Title: Improvements in methods of moulding
Inventor: PIGOTT ERNEST CARLYLE
IPC: B29C33/52
Filed: 1953-08-26
Abstract: Transparent models of engineering parts are moulded (see Group V) from cold-curing polyester resin for the purpose of photo-electric stress analysis on loading with or without heating. A suitable resin may be compounded by copolymerizing an unsaturated polyester resin based on a dihydric alcohol and a dicarboxy acid or acids with monomeric styrene using cyclohexanone peroxide as a catalyst and a solution of cobalt naphthenate in styrene as an accelerator.  The cyclohexanone peroxide catalyst is dissolved in the monomeric styrene, after which the solution is added to the resin, the whole being stirred until it is homogeneous.  Finally, the cobalt naphthenate in styrene accelerator is added and the mixture is allowed to stand until it is free from bubbles.  As resins of this nature contract on setting, the mould is of resilient material, or lined with such material, suitable examples of which are gelatine, polyvinyl chloride/plasticiser dispersions, and flexible phenolic resins or resol resins.  The gelatine is prepared from a solution containing 60 per cent dilute glycerine and 40 per cent pure gelatine added at a temperature of 80-85 DEG  C., allowed to dissolve, and digested at 130 DEG  C. to remove water and entrapped air.  The mould or mould linings and any necessary cores are cast from the gelatine, preferable casting temperatures being 105 DEG  C. for the mould and 90 DEG  C. for the cores.

Abstract: 819,433. Compressor and turbine rotor blades. McCULLOUGH, A. L., and WILKINSON, M.A. July 31,1956 [Aug. 1, 1955], No. 23611/56. Class 110 (3). [Also in Group XXV] In a turbine or compressor in which blades are mounted by their roots in undercut slots extending more or less axially at the periphery of a rotor disc, means are provided to prevent endwise movement of the blade roots in the slots. In the turbine rotor shown, undercut axial slots 11 are formed in the peripheral flange 12 of the rotor disc 13. Each blade 10 is formed with a correspondingly-shaped root 14 having a stop 15 at one end thereof, the blade stop abutting against one side of the peripheral flange 12 upon assembly. The bottom surface of each slot 11 is formed with a channel 17 so as to receive a blade locking strip 19, one end of the channel 17 being deepened as at 18. The locking strip 19 is flexible and has a shank 19a and projections 20, 22 extending in opposite directions at its ends, the projection 20 also having a tab 21. Upon assembly, a locking strip 19 is inserted in a channel 17 and is deformed. so that one end lies in the deepened portion 18 so that the blade root 14 may be entered into the slot 11 until the blade stop 15 abuts against the side of the rotor flange. The end of the locking strip 19 is then released so that the projection 20 bears against the outer surface of the blade stop 15 whereby the blade is locked in position. A recess 16 is provided in the stop 15 to receive the locking strip. In a second embodiment, Fig. 4, the channel 17<SP>1</SP> is of uniform depth across the bottom of the blade mounting slot and the locking strip is bent so as to form a projection 23 which is received in the channel. The stop 22<SP>1</SP> is of increased depth so as to lie against the side of the rotor flange. The end 22 of the locking strip may alternatively be received in a transverse slot formed at the bottom of the channel 17. A projection may be provided on the locking strip 19 at the end adjacent the projection 20 but extending in the opposite direction thereto so that when the locking strip is deformed, this further projection. engages the side of the rotor ftange and prevents the locking strip sliding out as the blade root is entered into the slot,.

(Cis-1,2-epoxypropyl)-phosphonic acid and its salts and esters are obtained by treating a formyl phosphonate, e.g. a compound in which R is a C 1 -C 5  alkyl, C 2 -C 5  alkenyl, aryl, or aralkyl radical with an ethylide which is substituted at the methylene carbon by an appropriate leaving group, i.e. a compound M#-CH#-CH 3  wherein M<SP>+</SP> is the leaving group, e.g. a di-(C 1 -C 5 )- alkoxy phosphinyl, di-(C 1 -C 5 ) alkyl or diaryl sulphonium, tri-(C 1 -C 5 )-alkyl- (or triaryl) - ammonium, di-(C 1 -C 5 )-alkyl sulphoxonium, tri-(C 1 -C 5 )-alkyl phosphonium or triaryl phosphonium cation. The process is suitably conducted in a solvent, e.g. an ether or dimethylsulphoxide, and the ethylide reactant may be prepared in situ in the solvent and the formyl phosphonate then added to the solution. When the products are esters they may be converted to the free (cis-1,2-epoxypropyl)-phosphonic acid, e.g. by hydrolysis with a mineral acid, hydrogenolysis, or treatment with trimethylchlorosilane followed by -aqueous hydrolysis. The phosphonic acid may then be converted to a salt, e.g. an alkali metal or alkaline earth metal salt, especially the calcium or disodium salt, by treatment with an aqueous solution of an appropriate base. Diethyl sulphoxonium ethylide is obtained by reacting diethyl sulphoxide with ethyl iodide in solution at 100-110 C. to form triethylsulphoxonium iodide and then treating the latter with sodium methylsulphonyl methylide in dimethyl sulphoxide. Triethylammonium ethylide is obtained by adding tetraethylammonium bromide in ether to an ethereal solution of phenyl lithium at 25 C. and decanting the supernatant liquid. Diethylsulphonium ethylide is obtained by reacting diethyl sulphide with ethyl bromide to form triethylsulphonium bromide and then treating the latter with an equivalent of sodium methyl sulphonyl methylide in dimethylsulphoxide.
