Title: Preparation of tris (vinoxy) propane
IPC: C08F20/62
Filed: 1959-09-11
Abstract: Tris(vinoxy) propane is used as a cross-linking agent in the preparation of polymers of methyl or ethyl acrylate and, if desired, acrylic acid.  In an example an ion-exchange resin is prepared by polymerizing methyl acrylate and tris(vinoxy) propane in dispersion in water containing polyvinyl alcohol and lauroyl peroxide, followed by heating the resulting copolymer beads in aqueous sodium hydroxide. Specification 838,020 is referred to.ALSO:In a process for the preparation of tris (vinoxy)propane from glycerol and acetylene, the acetylene is dissolved in N-methyl and/or N-ethyl-2-pyrrolidinone under pressure below 25 DEG C.; the solution is heated to a reaction temperature between 150 and 250 DEG C. at a pressure sufficient to prevent desorption of the acetylene, where it is reacted with the glycerol in the presence of an alkali metal-containing catalyst.  The glycerol and the catalyst may both be added after the acetylene solution has reached reaction temperature or part or all of one, but not both, may be present in the solution before it is heated to reaction temperature.  Suitable catalysts include alkali metal alkoxides or hydroxides or a dispersion of alkali metal in glycerol; 2-8% of catalyst based on the weight of glycerol is usual.  A stoichiometric excess of acetylene is preferred.  Pressures of 1500 to 5000 p.s.i. may be used.  2-Methyl-4-vinoxy-1,3-dioxolane is formed as a by-product.  Specification 838,020 is referred to.

Title: Electrically driven vehicles
IPC: B60C15/00
Filed: 1973-06-30
Abstract: 1480056 Control of D.C. motors LUCAS INDUSTRIES Ltd 11 June 1974 [30 June 1973] 31313/73 Heading H2J The motor control system described with reference to Figs. 1 to 4 of Specification 1,480,064 is provided with an accelerator pedal whose position determines the driving or regenerative braking condition of the motor and the value of the driving or braking current. In Fig. 5, a potentiometer 43 is connected between positive and negative lines 41, 42, so that movement of its slider by the accelerator pedal applies a positive or negative signal to a polarity sensitive circuit 44. If the selector switch is in the forward drive position, the circuit 44 will energize the forward contactor device F for a positive signal input and the braking contactor device B for a negative signal input, in either case the signal being applied through a rectifier 45 to the control unit 26 for the thyristors of the chopper and eommutating circuit. The dead band of rectifier 45 provides a period of zero signal input to the unit 26, Fig. 6 (not shown). The drive and braking currents may be made to vary with the vehicle speed and independently of each other, by varying the potentials on lines 41, 42 with the speed, for example to give an initially high and then a reducing drive current with speed increase and a maximum braking current at intermediate speeds, Fig. 7 (not shown). In a modification, Fig. 8 (not shown), the signal from potentiometer 43 is applied to unit 26 through normallyopen contacts (F2) of the device F, which contacts are in parallel with an inverter (46) in series with normally-open contacts (B2) of the device B whereby, when changeover between devices F, B occurs, there will be a period of zero signal input to unit 26 to reduce the current before the chosen contactors close. Fig. 9 shows a modification to use the position of the brake pedal, previously employed only to effect hydraulic braking, to provide a family of regenerative braking curves. The brake pedal controls the output of a potentiometer 52, 53 applied to an inverting amplifier 54, which varies the potential of one end of potentiometer 43, the operation of members 44, F, B being as in Fig. 5 and unit 26 being controlled by an amplifier 55 responsive to a control signal to operate in inverting or non-inverting mode, according to which device F, B is energized.
