Title: Rigid foam splints - made by casting a foamed (polyurethane) resin about a damaged limb
IPC: A61F13/04
Filed: 1971-05-17
Abstract: Splints made up suspending a broken limb in a hollow casing and casting a resin compsn. into it to form a rigid foam. Reinforcing bars are also suspended in the mould as desired. The amount of resin cast and cured in situ may be reduced by use of prefabricated blocks of similar material inserted in the mould. Use of cast or spray-up polyurethanes is claimed. Moulds are pref. made of, or lined with, material non-adhesive with the resin. The foam splints are much lighter than conventional plaster casts, are permeable to X-rays to allow monitoring of the limb and relatively permeable to air to avoid skin problems. Hardening of the foam does not involve the chilling effect of water evaporation. The foam may be cast in a crude mould and subsequently carved to a slimmer, more attractive profile.

Title: Fused salt baths for chemically pre-stressing glass - monitored and corrected for impurities by potential difference measurement process
IPC: G01N27/416
Filed: 1973-08-20
Abstract: Process for monitoring, adjusting and correcting impurities of fused salt baths, pref. KNO3 baths, used for chemically pre-stressing glass articles, takes pkace by measuring the potential difference between an electrode placed in treatment bath and an electrode placed in a reference bath of same salt. The two baths are separated from one another by a refractory membrane, esp. of glass, which contains ions capable of causing an exchange with at least some of the ions of the two baths. The electrodes are irreversible w.r.t. ions present in baths. Bath compsn. is corrected by known processes, according to measurements registered, in a way such that salt is partly replaced by new or regenerated salt and/or small amts. of reactants, neutralising impurities, are added. Slowing down of ion exchange through impurities, e.g. Pb2+, Ca2+, is immediately indicated by measuring electrodes, in order of 5-50 mv.

Title: Synthetic aperture processing for sideways looking radars
IPC: G01S13/90
Filed: 1973-10-30
Abstract: Information from the synthetic aperture radar (SAR) is recorded in a magnetic tape (1).

Title: Electric arc endless band cutting machine - has improved cutting speed afforded by modified arc voltage control
IPC: B23K9/09
Filed: 1973-12-07
Abstract: An endless board arc cutting electrode is continually traversed across a workpiece at a predetermined gap therefrom by an electric motor. Power from a power supply is passed to the electrode via a slip ring which is fed from a circuit comprising a transformer, a full wave rectifier and a rheostat. Nozzles supply a solution of sodium silicate to the workpiece at the point of cutting. The maximum output potential from the rectifier is arranged to be 3 to 4 volts. higher than the arc cut off potential and the sodium silicate solution prevents a short circuit between electrode and workpiece by breaking down and acting as an insulator once the gap current exceeds 1.5 times the optimum value.
