Title: Methods of and means for re-accelerating the drive through an automatic transmission mechanism with torque neutralizing means for automotive vehicles
IPC: B60W30/18
Filed: 1964-01-15
Abstract: In a combined clutch, gear shift and throttle control for a motor vehicle wherein initial shift movement effected manually or by an output speed responsive control 27 changes a double switch 30, 31 to disengage an electromagnetically operated main clutch 8, 9 and to energize a throttle closing solenoid 47, the throttle 6 is reopened during down-shift when the following three conditions are fulfilled: (1) a ratio establishing clutch sleeve 20 is applied against a friction synchronizing ring 17 with a predetermined force, (2) the main clutch driven element 9 overruns the driving element 8 and (3) the throttle pedal 38 is depressed. The ratio shift control 27 operates a rod 26 which acts through a spring centred lost motion coupling 25 on a shift fork 21 so that when the rod 26 has completed its movement and closed a switch 28 the shift fork 21 and clutch sleeve 20 are biased towards the new ratio position by a predetermined force. The throttle 6 is reopened by energizing a solenoid 33 through a switch 34 closed when the accelerator pedal 38 is depressed, the switch 28 and a switch 37, 41 closed when the clutch driven element 9 overruns the driving element 8. The solenoid 33 opens a switch 36 to de-energize the throttle closing solenoid 47. Establishiment of a new ratio changes the switches 30, 31 to re-engage the clutch 8, 9 and de-energize the throttle control solenoid 47. During re-acceleration the clutch 8, 9 may be partially engaged by supplying a reduced current to its winding 7 through a resistor 50 and a switch 49 operated conjointly with the switch 28. The throttle valve 6 is independent of the main pedal controlled throttle valve 4 and only partially closes the duct 3. In Fig. 3 (not shown) the above device is applied to the clutch control circuit described in Specification 1,028,964.

Patent ES-352366-A1 (ES)
Title: Numerical control system
IPC: G05B19/4103
Filed: 1968-04-03
Abstract: A numerical control system for moving a plurality of parts along reference ares between existing points and desired points comprises means for moving each part at a rate determined by its position error and the largest position error. As shown, in a numerical control system for positioning parts 22-24 of a machine tool by pulseresponsive servos 33-35, movement commands are read from a tape 37 by a reader 38 decoded in a decoder 39 and changed into binary form by a translator 40. The reader, decoder and translator are controlled by a tape reader control 41 for advancing the tape. The commanded end ofspan positions are fed from the translator to axes command registers 43-45 and an arc command register 46, for circular interpolation. Movement of a machine part is determined by pulses from electro-optical quantizers which are fed to axes actual position registers 51-53. The command and position registers are recirculating registers containing the same number of bits, one of which indicates sign. The instantaneous commanded positions of the parts are held in registers 54- 56 the contents of which are compared with the contents of axes command registers 43-45 by comparators 57-59. The outputs of the comparators, which are indicative of the existing errors between the instantaneous commanded positions and the commanded end positions are applied to interpolators 60-62 providing pulses to the servos 33-35. A clock pulse generator 64 feeds a binary frequency generator 65 providing a plurality of pulse trains to a feedrate adjust control 66, set manually, for a pulse generator 67 comprising a multiplier responsive to a programmed number, from the translator 40, stored in a register 68. The feedrate pulse frequency from the generator 67 is applied to a control network 80 which determines the rate at which command pulses are iterated by interpolators 60-62. Signals indicative of the interpolator output pulses are selectively fed to the control 80 by a function gate 88 enabled by an error magnitude control 93 determining the largest of the instantaneous position errors from comparators 57-59. During interpolation the existing position error is determined with respect to the commanded end position and pulse rates produced corresponding to such error. For a linear interpolation, first order equations are derived, for two or three axes, determining the resultant vector in dependence on the axes errors from the commanded positions. For circular interpolation, the end points are read into registers 43, 44 and the co-ordinates of the centre-point of the span read into registers 45, 46.

Title: Process for the continuous solution polymerization of 1,3-butadiene
IPC: C08F36/06
Filed: 1969-06-18
Abstract: 1,3-Butadiene is polymerized continuously in a homogeneous reaction mixture in a reactor in the presence of one or more hydrocarbon solvents and a catalyst formed from a hydrocarbon soluble organic cobalt compound and a hydrocarbylaluminium chloride compound, the cobalt concentration in the reactor being less than 5 p.p.m. by weight of the reaction mixture, by a process comprising adding the cobaltcontaining compound to one or more liquid streams, providing that all streams entering the reactor provide an average cobalt concentration which is at least one times the cobalt concentration in the reactor, the cobalt concentration in any cobalt stream when entering the reactor is less than 4 times the cobalt concentration in the reactor and that the cobalt-containing compound and the aluminium-containing compound are not added to one and the same stream having a 1,3-butadiene content of more than 1% by weight. The two catalyst components are preferably fed to one or more liquid solvent recycle streams and are preferably cobalt acetylacetonate and a hydrocarbylaluminium chloride compound which has been prepared by reacting a dihydrocarbylaluminium monochloride with water. In a preferred embodiment at least two liquid recycle streams are applied (A) benzene, having a 1,3-butadiene content of not more than 1 % w. and (B) butene, having at least 90% of the 1,3-butadiene feed and at least 90% of the unconverted 1,3- butadiene. In the examples 1,3-butadiene is continuously polymerized in a mixed solvent of benzene and butene in the presence of a catalyst comprising cobalt (II) acetylacetonate and a reaction product of diethylaluminium chloride. The polymerization is terminated by the addition of ethanol and as an anti-oxidant, a phenol. The mixture is steam stripped to remove the polymer from the stripped off solvent mixture and unreacted monomer, the stripped off mixture being purified by distillation to produce a larger stream of butene-1 and butadiene, and a smaller stream of benzene. These streams are recycled to the reactor, the benzene stream being mixed with a water containing stock solution and diethylaluminium chloride, and the butene stream, which contained butadiene feed, being mixed with the cobalt containing catalyst components. The resultant polymer, which has a high cis,1,4 content, is further polymerized by dissolving in styrene and further polymerizing with lauroyl peroxide to form a high impact polystyrene. A mixture of 1,3- butadiene and less than 10% by weight of isoprene may also be polymerized by the above described process. A solution of 6 % w. butadiene rubber, obtained by the above process, and 0.1% w. of lauroyl peroxide as initiator, in styrene was prepolymerized in a N 2 atmosphere at 90 C. and postpolymerized at 180 C. to produce a high impact polystyrene.
