Title: Method of manufacturing insulated wires
IPC: B29C48/92
Filed: 1967-09-12
Abstract: Insulation is applied to a pair of conductors by pulling them through an extrusion head and then through a bath of conductive liquid so that capacities formed between the liquid and the conductors are alternately included in a bridge circuit a component of the output of which controls the application of insulation to maintain the capacities equal. In Fig 1, a pair of conductors 12, 14 spaced in parallel passages in a tube 34 have plastic insulation applied in an extrusion head 10 and the cable so formed is pulled through a die 24, a guide block 38, and a conductive cooling liquid 28, by a motor-driven capstan 26 feeding a take-up roll 32. Each conductor forms, with a shielded electrode 50, a capacity which is dependent on the position of the conductor within the cable, and these capacities are alternatively connected to a high-frequency bridge circuit 44 by changeover relays 56 continuously operated from a low-frequency source 90. The high-frequency outputs of the bridge have a magnitude and phase-sense dependent on the magnitude and sense of deviation of conductor capacity from a desired value determined by a capacitor 60. These outputs are applied to a ring de-modulator 94 the low frequency outputs of which, due to inequalities of the two conductor capacities, are detected by a band-pass filter 108 and a low-frequency vibrator de-modulator 110. The output of de-modulator 110 is applied to a proportional plus integral servo-system 116 which restores symmetry in the cable by adjusting the transverse position of guide block 38. Variations of the output of de -modulator 94 resulting in variations in the average magnitude of the two conductor capacities relative to capacity 60 are detected by a low-pass filter 118 the output of which adjusts the speed of capstan motor 222 so that variations of insulation thickness are corrected.

Abstract: Aromatic hydrocarbons are separated from non-aromatic hydrocarbons by an extractive distillation process characterized by the following features :- (a) the extraction agent, e.g. propylene carbonate, contains as additives compounds similar to, but not the same as, those being extracted (e.g. if only benzene is to be extracted, then the additive may be xylene or Cg aromatics) (b) at least two extractivedistillation columns, shown as 14 and 19 in the Figure, are installed one behind the other in series, the downstream column 19 being operated at a lower pressure than the upstream column 14 and (c) the extract is treated in a number of column systems in series, each system corresponding to a desired product (e.g. column systems 23 and 29 for production of benzene and toluene respectively), each system consisting of an extractive stripper section (e.g. 23a), an extractive rectifying section (23b), a distillative rectifying section (23c) and a distillative stripping section (23d), the two extractive sections and the two distillative sections each constituting a pair of sections between which vapour and liquid interchange may take place, and the head of the extractive rectifying section (23b) being connected to the head of the distillate stripper section (23d), the bottom product of the preceding column system being fed between the a and b sections and the extraction agent being fed to the b section, while at the same time a pure aromatic extraction product is removed overhead from the c section, while a non-aromatic fraction is obtained as bottoms product in the d section. Sections a, b, c and d may be arranged differently from as shown in Fig. 3, e.g. a and b in one column and c and d in another. In a modification, the b section may be omitted if the next higher boiling product is not required in quantitative yield, e.g. as shown in column system 36, and it is also possible for the d section to be omitted in any system in which the heads product is not required in a pure state. The additive to the extraction agent may be already present therein, or may be added thereto, and part of the additive may be added directly to columns 14 and 19 at 41 and 42 above the feed-point of the extraction agent. In the Figure, benzene, toluene and xylene are recovered at 24, 31 and 37 respectively, and non-aromatics at 16, 21, 27, 34 and 39 all of which are combined in manifold 17.

Patent ES-377078-A1 (ES)
Title: Lighting systems for road vehicles
IPC: B60Q1/10
Filed: 1970-02-23
Abstract: A lighting system for a road vehicle includes a member which is movable longitudinally to adjust the inclination of the beams of the headlamps relative to the vehicle. Sensing means is provided on the vehicle for sensing the attitude of the body of the vehicle relative to the ground, and a light source is movable in response to the signal received from the sensing means. A pair of light-sensitive devices are positioned side-by-side, and control operation of an actuating device for moving the headlamp-adjusting member. The headlamp-adjusting member carries a mask which is movable between the light-sensitive devices and the light source, and which, when the headlamps are correctly inclined for a given attitude of the body of the vehicle relative to the ground, masks both of the light-sensitive devices from the light source. When both of the light-sensitive devices are masked then the actuating device is inoperative. However, if the attitude of the body of the vehicle relative to the ground changes the light source is moved accordingly, and light falls on one or other of the light-sensitive devices. When light falls on one of the light-sensitive devices the actuating device is operated to move the headlamp-adjusting member to adjust the inclination of the headlamp beams in the correct direction so that the stable position is reestablished where the mask blocks light from falling on both of the light-sensitive devices.
