Title: Moulding opt. foamed plastics eg. polyurethanes - using catalyst contg. metal salt, amine and boric complex for reduced demoulding time
IPC: C08J9/34
Filed: 1975-02-18
Abstract: Process for moulding opt. foamed plastics cush as polyurethanes, esp. of integral skin, flexible, semirigid, rigid or elastomeric type, uses a partially blocked catalytic system comprising (A) a metal salt (pref. of a divalent metal, e.g. dibutyl tin dilaurate, stannous octoate, dibutyl tin diacetate, dibutyl tin maleate, lead naphthenate or octoate) and (B) an amine which is totally neutralised with (C) a chelate type boric complex such as a glycoborate prepd. in presence of excess of glycol. (C) is pref. prepared from a polyol with >=3 OH groups (e.g. glycerol, 1,2,3- or 2,3,4-hexanetriol, trimethylol ethane or propane, 1,2,3-pentanetriol, and H3BO3 or esp. B2O3, excess of glycol being >=75%. (A) and the unstable (B)/(C) complex formed give a synergic effect leading to very short demoulding time (2 mins. c.f. 6-7 mins. previously) without increasing the cream time (approx. 20 secs.) and hence a reduced overall moulding cycle time. The catalyst system gives an initial slow temp. rise. (e.g. 20 degrees C in 24 secs.) due to (A) above followed by a rapid rise (50 degrees C in 18 secs.) due to (A) and liberated (B).

Title: Synchronous control of a static switch - overcomes parasitic effects at zero crossing by superposition of ramp and train of trapezoidal waveforms
IPC: H03K4/94
Filed: 1975-07-22
Abstract: The control circuitry for solid state switches, such as triacs initiates the switching operation on a change in value of some parameter such as temperature. The parameter is represented by the impedance of a thermistor. The circuit avoids parasitic effects at the change of state of the switches. Trigger pulses to the gate of the triac are derived from the superposition of a train of trapezoidal signals on a ramp waveform, the overall level rising to the trigger level. The amplitude of the trapezoidal waveform depends on the state of the thermistor which is connected between earth and the collector of an earthed-emitter transistor whose base receives a half-wave rectified supply. The output is fed in parallel with the ramp waveform to a trigger generator and the triac.
