Title: Compressed air drive for electric circuit breakers with air damping
IPC: H01H33/32
Filed: 1943-02-22
Abstract: 560,742. Actuation of switches. AKT.- GES. BROWN, BOVERI, & CIE. Feb. 22, 1943, No. 2902. Convention date Feb. 20, 1942. [Class 38 (v)] A pneumatically-actuated disconnecting or other switch has its movement damped pneumatically towards the end of the switching movement by a damping cylinder containing a piston, and the compressed air is supplied to both cylinders simultaneously, the air supplied to the damping cylinder being compressed by the kinetic energy of the moving parts, and the arrangement further being such that, up to the commencement of damping, the pressure in the two cylinders is equalized. The supply pipe 18 for driving-piston 2 supplies also the damping cylinder 11 through non-return valve 10 and discharge bore 16 adjusted by throttle 17. When the movable switch-member 7 has opened the distance a, the piston 12 is driven to compress the air in 11 and produce the necessary damping, rebound being prevented by leakage through bore 16 and past the piston 12. Alternatively, valve 10 can be arranged in bore 16 and adjusted as to the amount of clearance, or the piston and cylinder may have recesses which overlap at the end of the,movement, Figs. 2, 3 (not shown). In Fig. 5, a pair of damping pistons 12, 12a, located on the piston rod 5 itself, work in cylinders 11, 11a in the driving piston 2. The rod 5 is formed with the bore 16 interconnecting the cylinders 11, 11a and the equalizing and supply pipe 18 is formed in piston 12. When pressure is admitted at 8, the parts 2, 12, 12a move together until 2 is arrested at the left-hand cylinder-head, whereupon the air is compressed in cylinder 11 by piston 12 and discharges slowly into cylinder 11a. A simple-acting form of this last is also described, Fig. 4 (not shown).

Title: Electric installation permitting of selecting and controlling local electric circuits from a distance
IPC: H04Q9/06
Filed: 1926-02-05
Abstract: 247,553. Favarger et Cie Soc. Anon. Feb. 11, 1925, [Convention date]. Selective distant-control systems; order apparatus.-An installation for selecting and controlling from a distance through a pair of line wires local circuits supplying selectors, counting mechanism, lamps, &c. comprises at the sending station a generator and commutators permitting of sending currents of different voltage and direction, and at the receiving station at least two polarized relays and at least one relay operable only at a voltage higher than that operating the polarized relays, the coils of the relays being supplied ' simultaneously from the line and their armatures connected in the local circuits supplied by a second generator whereby current is allowed to pass into one or other of the local circuits according to whether the armature of the higher voltage relay is actuated or not. In this arrangement the number of higher voltage relays, actuated by successively higher voltages, is equal to the number of pairs of local circuits to be selected less one. Fig. 1 shows an arrangement for selecting and controlling- four local circuits 24 - - 26 supplied from a generator and supplying devices 27 - - 30, when the armatures 11 of polarized relays 8 and the armature 13 of relay 9 are suitably actuated from the line wire 3, 4 extending to the sending station, which is provided with a generator in two parts 1, 2 connected in series and four commutators I - - IV. The armature 13 is actuated only when the two parts 1, 2 of the generator is connected in the circuit 3, 4 supplying the coils 10, 9. On closing commutator I armatures 11 are actuated and the local circuit 23 only is completed. On closing commutator II a current is sent through line 3, 4 in the opposite direction again actuating the armatures 11 but completing only the local circuit 24. Closing commutator III sends a higher voltage current which actuates the armatures 11 and 13 and completes the local circuit 25 only, and closing commutator IV sends the higher voltage in the opposite direction and completes local circuit 26 only. The selection of the local circuits may be effected with the use of only two polarized relays if their armatures have two operative positions and also an intermediate position of rest. In an arrangement similar to that shown in Fig. 1 for selecting six local circuits, the sending station has six commutators and a generator in three parts connected in series, and the selection at the receiving station is effected by four polarized relays operable by one part of the generator, a higher voltage relay operable only by two parts, and a still higher voltage relay operable only when the three parts of the generator are in circuit. The line wires may be branched to two sending stations and to two receiving stations.

Title: Improvements in or connected with wheel tilting mechanisms for motor vehicles
IPC: B60G21/00
Filed: 1947-02-05
Abstract: 620,967. Movable stub axles. CORNELISSE, J. J., and CORNELISSE, C. G. Feb. 5, 1947, No. 3418. Convention date, Feb. 28, 1946. [Class 108 (ii)] In a motor vehicle in which, when it is steered to the right or left, its rear wheels 1, are tilted clockwise or anticlockwise about horizontal axes intersecting that of the rear axle, the tilting mechanism comprises, for each wheel, pressing members 7, 8 mounted above and below the tilting axis and arranged to slide in housings 9, 10 secured to the back axle 6, operating means being contained in the housings to co-operate with the pressing members and comprising cams 13, Fig. 4, fixed to a spindle 15 which rotated by the steering mechanism. A crank 16 coupled to the steering mechanism rotates the spindle 15 together with the cam 13 which, bearing on a pivoted lever 11 causes the member 7 to move out from the housing 9. The lower housing 10 contains a similar mechanism the cam of which is angularly displaced relative to the cam 13 so that when the latter forces the member 7 outwardly the tilting of the wheel 1 forces the member 8 back into the housing 10. The spindle 15 carries at its lower end a crank 18 connected by a link 19 to a corresponding crank on the opposite side of the vehicle, so that a single link from the steering gear operates simultaneously the tilting mechanism on each side of the vehicle. Each member 7 preferably contains a central pin 7a which can slide against the action of a resilient cushion 7b. The tilting axis for each wheel comprises longitudinally spaced ball joints 2. To ensure that the tilting mechanism only operates when the vehicle speed exceeds a predetermined value, its operating crank is connected by a rod 17 to a movable pivot on a bracket 20 which can swing about a horizontal axis x on the chassis. The lower end of this bracket is connected by a link 26 to the steering gear. The movable pivot comprises a nut 25 mounted on a screwed spindle 21 which can be rotated by an electric motor 23 mounted on the bracket. At normal speeds, the nut 25 is at the top of the spindle and coincides with the turning axis of the bracket 20 ; rotation of the bracket by the link 26 then causes no longitudinal movement of the link 17. When a predetermined speedis exceeded. a centrifugally operated switch (Fig. 9, not shown) causes the motor to rotate the screwed spindle, and the nut travels to the bottom of the bracket ; movement of the link 26 then operates the tilting mechanism through the link 17. To compensate for the change in effective length of the link 17 caused by movement of the nut, the part A, B of the arc of swing of the bracket 20 is arranged to have no effect on the wheel tilting mechanism. Switches 32, 34 are operable by the nut 25 at respective ends of its travel in order to switch-off the motor 23.

Filed: 1924-02-12
Abstract: g -Tetrahydroquinolone of the formula <FORM:0230607/2/1> is prepared by condensing p-toluenesulphonanilide with b -chlorpropionic acid to give p-toluenesulpho-b -phenylaminopropionic acid, and treating the latter with phosphorus oxychloride to obtain N-p-toluenesulpho-b -chlortetrahydroquinolone; upon acid hydrolysis the latter compound yields g -tetrahydroquinolone.  If the ring closure is effected with phosphorus pentoxide (preferably in xylene suspension) a non-chlorinated intermediate product results.  Examples are given of the method, hydrolysis being effected with a mixture of hydrochloric and acetic acids or with sulphuric acid.  g -Tetrahydroquinolone is an initial material for the manufacture of drugs and photographic sensitizers.  It yields a benzoyl derivative with benzoyl chloride, a hydrazone with phenylhydrazine, and a benzal derivative with benzaldehyde: it forms a nitro derivative which yields on simultaneous reduction and condensation with zinc and cyclohexanone, the hydrazone, <FORM:0230607/2/2> which, on treatment with dilute sulphuric acid, gives the tetrahydrocarbazole derivative, <FORM:0230607/2/3> g -Tetrahydroquinolone also condenses with diketones; for example with isatin it gives the acid, <FORM:0230607/2/4> which loses carbon dioxide when heated, forming the base, which latter by oxidation yields the quinoquinoline, <FORM:0230607/2/5>
