Title: A process for the production of glycols from fatty acids
IPC: C07C31/20
Filed: 1935-09-12
Abstract: High molecular glycols are produced by treating persulphates with saturated fatty acids containing at least eight carbon atoms in the molecule suspended in sulphuric acid or oleum, if desired in the presence of boric acid.  In an example, stearic acid is treated with potassium persulphate in the presence of monohydrate, boric acid and silver sulphate, and the resulting wax saponified. Heptadecene glycol is thus obtained, the saponifiable portion of the wax comprising oxidized acids and unchanged stearin acids. Natural mixtures of fatty acids, e.g. coconut, palmkernal and hardened vegetable and animal oils fatty acids may be employed as well as the pure acids. Caprylic, capric, lauric, myristic, pentadecylic, palmitic, arachic, behenic, cerotic and melissic acids are mentioned.

[Also in Division B71 A carriage (see Division B7) for a ropeway is attached to a haulage cable 18 by a pair of clips spaced apart in the lengthwise direction of the cable, each clip having two gripper arms 20, 21 pivoted together by a pin 22 at one end, and being mounted so that while engaging the cable they are free to swivel to a limited extent relative to the carriage about an axis transverse to, and substantially intersecting, the centre line of the cable. The weight of the carriage and its load causes the gripper arms to grip the cable, the gripping force being transmitted by a rectangular reaction ring 31, slotted into the sides 10 of the carriage, to a pair of wedge members 30 which at their upper ends are provided with pins 32 engaging vertical slots 34 in the carriage frame, and at their lower ends have hemispherical surfaces 30b which engage part-spherical sockets in the gripper arms. Cross-links 33 connect the ends of pins 32, and a rod 36 in the ring 31 prevents the gripper arms from falling out when they are not engaging the cable. The surfaces 30b on wedge members 30 form the pivots for the gripper arms. In a simpler clip form, Fig. 5, the reaction ring 131 is rigidly attached to the carriage frame and bears directly on wedge faces 130 of the gripper arms 120, 121, which latter have cable gripping pads 123, 124 pivotally attached to them by screws 128 engaging in elongated slots in the gripping pads. The upper edges 126 of the pads 123, 124 form part-cylindrical surfaces, as do the corresponding faces 127 of the gripper arms.

Class 70 Mouldable objects are obtained by forming at room temperature a mixture of rubber hydrochloride and such a quantity of liquid plasticizer that the mixture obtained is plastically deformable at room temperature and then heating to gelatinize the mixture. The plasticizers may be chlorinated diphenyl, tricrensyl phosphate, butyl stearate, dioctyl phthalate, dibutyl phthalate and chlorinated paraffin. Preferably 90-120 parts of plasticizer are used per 100 parts of rubber hydrochloride. Excess plasticizer may be removed by the use of a solvent which will not dissolve rubber hydrochloride such as petroleum ether, acetone, ether, ethyl acetate, methanol and benzene.

Abstract: 885,736. Change-speed controls. REGIE NATIONALE DES USINES RENAULT. Aug. 12, 1958 [Aug. 22, 1957], No. 25891/58. Addition to 769,862. Class 80 (2). In the automatic change-speed control of the parent Specification wherein a succession of current pulses is fed to a relay winding 6 by charging a capacitor 10 from a battery 5 and discharging it to the relay through contacts operated by the gear output shaft so that the mean intensity of the current in the winding is proportional to the speed of the said shaft, the relay acting to energize a gear-change coil 9 at a predetermined speed, means are provided to increase relay stability. In Fig. 1 wherein the capacitor 10 is carried by a bar-type commutator 1 rotating with the shaft as described with respect to Fig. 2 of Specification 799,196, the relay carries an additional winding 16, battery-connected in series with an accelerator-controlled variable resistor 11, the winding 16 opposing the winding 6 to render the relay operating speed substantially independent of the battery voltage and coil temperature, and a damping capacitor 12 is shunted across the winding 6, the relay armature, as shown, or core, is polarized thus permitting the use of a sensitive relay whilst avoiding inadvertent relay energization by the winding 16, and the relay carries a further winding 17 energized through a variable resistor 26 when the relay is energized, which winding 17 supplements the winding 6 thus stabilizing the relay by effecting a current-intensity difference between the opening and closing of the relay contacts. In Fig. 2, not shown, dispensing with the winding 17, relay stabilization is effected by feeding the current to the winding 16 through a further variable resistor in series with the variable resistor 11, this further resistor being short-circuited when the relay is de-energized by a switch which may be connected to the relay armature or operated by an auxiliary relay shunted across the coil 9. In Fig. 3, wherein the single relay winding 6 is fed through a diode or crystal rectifier 24, a resistor 22 is in parallel with the circuit section including the commutator 1, the diode 24 and the winding 6, a resistor 23 is shunted across the capacitor 12, and the winding 6 is earthed through the variable resistor 11, relay stabilization may be effected either by a further variable resistor 25, as shown, in series with the resistor 11 and short-circuited through a switch 19, 20 connected to the relay armature and closed when the relay is energized, or by a separate winding as in Fig. 1.

The nitrogen atoms present may be converted to the quaternary state in aqueous or water-alcohol solutions. Paper may be treated either by impregnation of finished paper or by addition of the resin to the head box of a paper forming machine prior to formation of the web. From 0.1-5% by wt. of resin may be used which is subsequently dried and hardened.

A vehicle clock winding means is automatically operated by varying pressure caused to be exerted upon a diaphragm, piston or the like by the lubricant or coolant of the engine-lubricating or cooling system of the vehicle. Downward movement of a diaphragm m, Fig. 2, caused by variation in fluid pressure in the lubricating or cooling system of the vehicle is transmitted by a piston rod i, a .spring k, a cylinder h, a double armed forked lever e 1 , e, to a pawl f which steps on a ratchet wheel d in the winding train of the clock. When the mainspring is fully wound downward movement of the diaphragm only causes tensioning of the spring k. In another embodiment, Fig. 3, upward movement of a diaphragm m is transmitted by a rod q and a spring k to a rack o which meshes with a wheel p connected by a one way clutch to a shaft b in the clock winding train. The spring k presses the rack q against a collar r. If desired a second spring may be placed between the rack q and the collar r.
