Title: Process for producing fluoroalkyl vinyl ethers and compounds resulting therefrom
IPC: C07C43/17
Filed: 1953-05-18
Abstract: Fluoroalkyl vinyl ethers of the formula <FORM:0742083/IV(a)/1> where R is H or methyl and R1 is a fluorine substituted alkyl radical are polymerized to form resins useful in making coatings and films. Specified monomers are trifluoroisopropyl, 2,2,2-trifluoroethyl, 2,2,3,3,3-pentafluoropropyl and 2,2,3,3,4,4,4 - heptafluorobutyl vinyl ethers.ALSO:The invention comprises fluoroalkyl vinyl ethers of the formula <FORM:0742083/IV(a)/1> in which R represents methyl or H, and R1 represents fluorine substituted methyl, or a fluorine substituted alkyl radical having at least two carbon atoms.  These are prepared by reacting a fluoralkanol with acetylene at elevated temperature and under pressure in the presence of a corresponding alkali metal fluoroalkanolate.  Preferably the fluoralkanol is treated with an alkali metal in a solvent such as ether, and after removal of the ether, the resulting mixture is vinylated with acetylene.  The alkali metal hydroxides may also be used to produce the fluoroalkanolates but the water thus introduced must be removed prior to vinylation.  The products find use as inhalant anaesthetics, solvents and intermediates.  They may be subjected to bromination to form bromine addition products or may be polymerized.  In examples (1) trifluoroisopropanol is added to a suspension of potassium in ether, the mixture is charged into a bomb, after removal of ether, heated to 150 DEG  and acetylene is introduced under pressure to give trifluoroisopropyl vinyl ether, on fractional distillation; (2) 2,2,2-trifluoroethanol is reacted as in (1) to give 2,2,2-trifluoroethyl vinyl ether; (3) 2,2,3,3,3-pentafluoro propanol is reacted as in (1) to give 2,2,3,3,3-pentafluoropropyl vinyl ether; (4) 2,2,3,3,4,4,4-heptafluorobutanol is similarly treated to give 2,2,3,3,4,4,4-heptafluorobutyl vinyl ether.  Specification 703,434 is referred to.ALSO:An inhalant anaesthetic composition comprises 2, 2, 2 trifluoroethyl vinyl ether in admixture with oxygen. Trifluoroisopropyl vinyl ether and other compounds of the formula <FORM:0742083/VI/1> where R is H or methyl and R1 is a fluorine substituted alkyl radical, may also be used.

Filed: 1935-05-16
Abstract: 456,847. Vehicle lifeguards. MORRIS, J., 1, Buxton Street, Heywood, Lancashire. May 16, 1935, No. 14299. [Class 103 (ii)] A vehicle lifeguard is held normally in an inoperative position by means of a catch which is releasable by backward pressure on the guard and by a device under the driver's control, means also under the driver's control being provided which permit the driver to counteract the weight of the guard to prevent it from dropping, and which serve to restore the guard and catch to the inoperative position. The guard shown comprises a fixed bumper 10 and a second bumper 12 secured to arms 13, Fig. 2, pivotally mounted on a transverse shaft 14, and to an arm 27 fixed to the shaft. In order to support the bumper 12 in inoperative position the arm 27 has a notched projection 26, Fig. 4, normally engaged by one arm 23 of a spring-rotatable catch mounted on a fixed bracket 22, the other arm 24 of the catch engaging a recess 28 in a pivoted locking-member 29 which carries a shaft 31 to which are secured the inner ends of cranked rods 34, 35 connected at their other ends to movable impact bars 32, 33 spring-pressed forwardly of the bumpers 10, 12. When the impact bars meet an obstruction they force the rods 34, 35 and shaft 31 rearwardly thus rotating the locking member 29 in a clockwise direction, Fig. 4, to release the catch which is then spring-pressed in an anticlockwise direction, thus releasing the arm 27 and allowing the bumper 12 to fall. To provide control by the driver an arm 16 fixed on the shaft 14 is connected by a link 17 to a pedal 18, and the locking member 29 is connected by a rod &c. 37 to a spring-pulled lever 38, the pedal and lever being engageable respectively by the driver's foot and heel, so that by depressing his heel the catch 23, 24 is released, pressure on the pedal then counterbalancing the weight of the guard. The guard may cover the front wheels only or the whole front of the vehicle. An expansible shield of articulated laths may be secured between the bumpers 10, 12 or a vertically-slidable, wire-mesh guard may be secured to the bumper 12 and slide in fixed side-guides. The bumper 10 may be omitted. The lever 38 may be pivoted on the hand brake lever &c. Movement of any of the parts may, through articulated levers &c., operate contacts to open the sparking circuit, in the case of a motor vehicle fitted with such a circuit.

Multi-way repeating systems for telephony comprise a number of lines A - - D, Fig. 1 each of which is coupled to the output circuit of one amplifier and to the input circuits of all the other amplifiers so that currents incoming over one line are repeated in amplified form over the others. A supervisory circuit S is coupled by the circuit 68 to all the lines so as to receive the amplified currents and by a group of transformers 69 to the input circuits of all the amplifiers. Each group of transformers 14 - - 17 may have a common primary winding and may be connected directly to the mid-points of the differential transformers instead of through the potentiometers 12a - - 12<d> In a modification, Fig. 2, the secondaries 72 of all the input transformers are connected in parallel. One side of the parallel circuit is connected to a common lead going to one side of all the grid circuits and the other side is connected via individual reverse secondary windings 71 to the other sides of the grid circuits.

Abstract: 219,946. Guy, B. A. July 31, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Electromagnetic switches; electrically released switches; contacts. - In order to facilitate the opening and closing movements of a knife-blade switch, one of the faces of the usually fixed clip contacts is movable, electromagnetically, to release and admit the knife blade without friction, a spring serving normally to hold the movable cheek in the contacting position. As shown applied to an electromagnetically-operated switch or relay, the switch is brought to the closed position by energizing for a moment two electromagnets 15, 10. The electromagnet 15 attracts its armature 14 and moves the knife blade 12 into engagement with the clip contacts, which have faces 1, 2. The face 2 is carried by an armature 6 pivoted at 3, and the energization of the electromagnet 10 withdraws the face 2, against the, action of the spring 7, so as to admit the knife blade without friction. When the switch is closed, the momentary energization of the electromagnets ceases and the knife blade is frictionally held in the clip contacts against the action of the spring 16. To open the switch, the electromagnet 10 only is energized thereby releasing the friction grip. It is stated in the Specification that the movable contact face and the knife blade may be controlled by mechanical means.
