Title: Electric vehicle propulsion system
IPC: B60L50/15
Filed: 1980-02-09
Abstract: Each wheel of an electric vehicle is driven by a respective stepping motor 32, 34, 36, 38 supplied by an alternator 16 driven at constant speed by an engine 12. Each motor has a first pair of stator windings (147, 151) supplied from respective alternator phases with rectified AC pulses of variable frequency and phase through SCRs Figure 5 (not shown) controlled by members 76, 86 in response to driving pedal and steering controller 72. When increased power is required members 76, 86 control further SCRs Figure 10 (not shown) to supply a second pair of stator windings (647, 651) on each motor with pulses of DC from a battery 48. When the vehicle speed reaches the alternator speed the SCRs Figure 5 (not shown) are turned off and further SCRs Figure 6 (not shown) are controlled to pass AC through the windings (147, 151) to drive the motors as synchronous motors. During regenerative braking the AC output of the motors is rectified in member 68 to charge the battery 48, the braking force being varied by connecting the motor windings in series or parallel. Members 72, 76, 80, 86, 90 vary the supply frequency of the motors on one side relative to the other to provide steering. In a modification Figures 12 and 13 (not shown), combustion of wood fragments, in the chamber of a pressure vessel mounted on the vehicle rear, is initiated by igniting in the chamber gas from an external source. Air is supplied by compressor. As soon as combustion has become self-sustaining, the supply of gas is terminated. Meanwhile, the pressurized gas emitted from the vessel is discharged through a valve into a turbine which drives the alternator 16. <IMAGE>

Title: A process for producing a transparent thermoplastic graft copolymer composition
IPC: C08F2/00
Filed: 1982-02-01
Abstract: A thermoplastic resin composition is prepared by graft copolymerizing under emulsion polymerization conditions, an unsaturated monomer mixture consisting of at least two unsaturated monomers selected from alkenyl aromatic monomers, methacrylate monomers and vinyl cyanide monomers onto a diene polymer latex having a gel content of from 60 to 90% by weight and an average particle size of from 0.1 to 0.5  mu m. The amounts of diene polymer latex (in terms of solids) and of monomer mixture are from 5 to 40% and from 95 to 60% by weight, respectively. The composition of the monomer mixture is so chosen that the refractive index of the resin phase if the graft copolymer is substantially identical to the refractive index of the rubbery diene polymer of the latex. By carrying out the graft copolymerization in the presence of a sodium or potassium di(C1-C6 alkyl and/or C6-C9 aryl)dithiocarbamate i.e. R2N.(CS.SM) and ensuring that the grafting degree of the graft copolymer is within the range form 30 to 70% by weight, it is possible to produce a thermoplastic resin composition having excellent transparency, impact resistance and processability.
