Abstract: 871,121. Transistor pulse manipulating circuits. BUSH & RANK CINTEL Ltd. Dec. 14, 1959 [Dec. 12, 1958], No. 40143/58. Class 40(6) An amplitude discriminator comprises a transistor 3 connected in emitter follower configuration having its emitter connected via a resistor 4 to a source of bias potential. The emitter is also connected through a capacitor 9 to the emitter of a second transistor 10, of opposite conductivity type, connected in common base configuration, having a diode 11 connected between its emitter and base. The value of the capacitor 9 is arranged such that with the input resistance it forms a differentiating circuit for incoming signals, and the diode 11 is arranged to conduct when transistor 10 is non conductive. As described, the transistor 3 is an NPN transistor and the bias for it is provided by a resistance network 5, 6, 7 connected between earth and a +6v. supply. A train of positive pulse applied to transistor 3 will cause the transistor to conduct if the amplitude of the pulses exceeds the value determined by the bias, the resulting output is differentiated and has its negative going spikes clipped by the diode 11. The transistor 10 to which the pulses are applied is PNP type, and its output may be amplified by an amplifier comprising a transistor 14 in emitter follower configuration followed by a common emitter stage 18. For negative going trains of pulses, the conductivity types of transistors 3 and 10 may be interchanged, the amplifier comprising transistors 14, 18 being suitable for either type.

Abstract: Mono-epoxy compounds are polymerized using as catalyst a mixture of a compound of the formula M(OR)xRy(Hal)z and a metal halide in which the metal is different from M, where M is a metal of Group 2 or 3 of the Periodic Table, R is an alkyl or aryl group, y is an integer, x and z are integers or zero, and x+y+z equals the valency of M. The epoxy compounds are defined as having the formula:  <FORM:0876648/IV (a)/1> where R1 and R11 are each a hydrogen atom or hydrocarbon radical, R111 is hydrogen or a hydrocarbon, halohydrocarbon, aryloxyalkyl, alkylaryloxyalkyl or haloaryloxyalkyl radical, and R1 or R11 may be joined to R111 to form a cycloaliphatic ring. Specified compounds are ethylene, propylene, styrene and cyclohexene oxides, and phenyl, chlorophenyl, tolyl and naphthyl glycidyl ethers. Copolymers and block copolymers are included.  Examples of the first group of catalysts are aluminium triethyl, triisobutyl, diethyl chloride, ethyl dichloride, ethyl diethoxide and ethyl ethoxy chloride; zinc ethyl ethoxide, ethyl chloride and diethyl; and magnesium di-isobutyl, ethyl isopropoxide and ethyl chloride. Suitable metal halides are cupric, magnesium, zinc, ferric, aluminium, titanium and stannic chlorides.  Solvents may be used, and temperatures may range from 0 DEG -200 DEG C. and pressures from 1-40 atmospheres.  Polymers of styrene oxide or cyclohexene oxide may be freed from catalyst by treating with alcohol, washing with dil. HCl and with water, extracting with benzene and distilling.  Other polymers may be purified by distilling off excess monomer and extracting with benzene from which they are precipitated by petroleum ether.  Polymers having molecular weights above 20,000 can be obtained and they are useful as thickening agents or, in the case of ethylene oxide, as water-soluble films.ALSO:A catalyst for the polymerisation of epoxy compounds comprises a mixture of a compound of the formula M(OR)xRy(Hal)z and a metal halide in which the metal is different from M, where M is a metal of Group 2 or 3 of the Periodic Table, R is an alkyl or aryl group, y is an integer, x and z are integers or zero, and x+y+z equals the valency of M.
