Title: Apparatus for supervising the running of automatic thread winding machines
IPC: B65H63/00
Filed: 1953-02-03
Abstract: 771,880. Winding machine control means. REINERS, W. Feb. 3, 1953 [Feb. 4. 1952], No. 3030/53. Addition to 740,685. Classes 120 (2) and 120 (3). Apparatus for supervising the running of a thread or yarn winding machine by the method claimed in Claim 2 of parent Specification comprises mechanisms respectively measuring the rate of thread breakages and counting the number of thread tying failures, the mechanism measuring the rate of thread breakages including means by which the breakages are automatically related to a physical value constituted by the dissipation of heat in a heated element or the controlled reduction in the volume or pressure of a fluid, and an electrical circuit through which interruption of the winding operation or exchange of the supply bobbin is automatically initiated when said rate reaches a predetermined value, the mechanism counting the number of thread tying failures including a warning device which is automatically actuated when said number reaches a predetermined value. In the arrangement shown a driving shaft 36 which is rotated through a complete revolution every time an interruption in the thread supply occurs, carries a disc 200 which by means of a projection 201 operates on a roller 204 and depresses a piston 207 in a cylinder 208. The cylinder 208 is connected with a further cylinder 213 by a pipe 209 having a spring loaded ball valve 210 therein. The cylinder 213 is connected to a reservoir 240 by a pipe 211 carrying a regulating cock 212 and the reservoir 240 is connected to the cylinder 208 by a conduit 241 and a ball valve 242. The cylinder 213 has therein a piston 215 which is coupled to a toothed wheel 219 by means of a piston rod 216 carrying a rack 218. The upper end 220 of piston rod 216 is disposed below contacts 29 and 30. In operation each revolution of shaft 36 causes the transference of a definite quantity of fluid from cylinder 208 to cylinder 213 with a consequential upward movement of piston 215. If sufficient time elapses before the next revolution of shaft 36 the transferred fluid can leak back to the reservoir through the cock 212. If however there are repeated operations of the shaft 36, that is the rate of thread breakages is high, there is a build up of fluid in cylinder 213 which eventually causes the piston rod 216 to cause contact of the contacts 29 and 30. The latter through an electric circuit operate the bobbin exchanging mechanism or cause the interruption of the winding operation. In another embodiment an electrically heated bi-metallic strip is used and in a further embodiment an electric heating element and a contact thermometer are used.

Title: Improvements in stabilizing devices for vehicles
IPC: B60G21/08

Abstract: 513,154. Road - vehicles undercarriages; hydraulic and friction shock-absorbers. ESPINASSY DE VENEL, G. d'. Feb. 1, 1938, No. 3164. Convention date, Feb. 4, 1937. [Classes 108 (ii) and 108 (iii) ] In a road vehicle having a stabilising device controlled by a centrifugal, gyroscopic or like detecting-means, the stabilising device is of the double-acting type, i.e., responsive to relative movements of the body and chassis in either direction, its parts are entirely free, i.e., the stabilising device is wholly inoperative, when the detecting means are unaffected, and the stabilising device is altogether independent of the spring suspension. In the construction shown in Figs. 3-5, the stabilising means comprise four electro-magnetically operated friction shock absorbers 6-9, an arm 14, Fig. 4, on each of which is connected by a link 16 to one of the vehicle wheels and carries a pair of contacts D, T adapted to co-act with a contact I mounted on a frictionally held arm 15. The several contacts D, T are associated with two other sets of contacts 29a, 29b, 30a, 30b and 60a, 60b, 65a, 65b, which co-act respectively with contact arms 26a, 26b and 58a, 58b conrolled by detecting gyroscopes 21t and 21r. If an electric circuit is completed due to operation both of the gyroscopes and of the arms 16, then an electromagnet 13<1> disposed in a disc 13 of each of the appropriate shock-absorbers is energised, presure is exerted between such disc and a fixed disc 11, and a stiffening of the requisite, shockabsorbers to oppose the pitching or rolling movement is effected. In addition, a pendulumoperated device may be added as a detector, being connected with the steering mechanism so as to become operative when turning-movements are executed. In place of the friction shock-absorbers, fluid shock-absorbers such as that shown in Fig. 7 may be employed. Each of these includes a piston 121 which displaces fluid freely under normal conditions, but, owing to movements of valves D, T during pitching or rolling, the flow is resisted and the shock-absorbers stiffened on the approprate side or end of the vehicle. Or, fluid shock-absorbers connected with a source of pressure may be substituted. An arrangement, Fig. 8 (not shown), is also described for associating a pair of fluid shock-absorbers with a gyroscopic detector and also with control means linked with the steering mechanism.
