Title: Improvements in and relating to Electromagnetic Switches.
IPC: H01H71/24
Filed: 1917-02-01
Abstract: 112,983. British Thomson - Houston Co., (General Electric Co.). Feb. 1, 1917. Electro-magnetic switches. - An electro-magnetic lock-out switch for starting electric motors has a shunt coil 10 energizing the upturned polepiece 14 and a series holding-out coil 32 energizing the pole-piece 31. The pole-piece 14 acts upon two separate armatures; one, the armature 24, depending from the contact-carrying magnetic member 23 pivoted at 17, and the other, the armature 33, directly pivoted at 17. The pivot 17 carries also a frame 27 provided with an holding-out armature 30 co-operating with the holding-out magnet 31. The frame 27 is provided with an offset cross-bar 28 between which and the armature 33 a compression spring 34 is located. The parts assume the positions shown by gravity and, when the coil 10 is energized, it serves to retain the switch in the ' off ' position by the attracton between the pole-pieces 14 and the armature 24 notwithstanding the counter-attraction between the member 23 and the core 11. The attraction between the pole-piece 14 and the armature 33 compresses the spring 34 which tends tomove the frame against the action of the holding-cut magnet. When the series current in the coil 32 diminishes sufficiently, the frame is released and, under the action of the spring 34, the offset portion 28 strikes the armature 24 and knocks i away from the influence of the polepiece 14 whereupen increased attraction between the member 23 and the core 11 causes the magnetic closure of the switch. A copper band 15 retards the rise of the flux in the pole-pieces 14 and softens the blow of the armature 33 on the pole-piece. A non-magnetic adjusting screw 25 serves as an abutment for the end of the armature 24 and determines the size of the gap between the armature and the pole-piece 14 and, consequently, the current-setting of the switch.

Abstract: 885,311. Clamp fastenings; buckles. CARTER, A.G. Jan. 17, 1958, No. 1710/58. Class 44. A safety belt buckle has a pair of substantially flat coupling members 10, 17, which when the buckle is fastened overlap each other, one of the members having an abutment surface 18 extending across the direction of belt tension, and which engages with a corresponding abutment surface 19 on the other member for transmitting the belt tension, and in which there is provided on one of the members spaced disengageable locking means 20 and 20a (not shown) located outwardly in a direction across the belt tension of the abutment surfaces whereby separation of the coupling members in a direction normal to the plane of overlapping is limited. The coupling member 10 is provided with a slot 11 for engagement by a belt section 12 and with an aperture 14 which engages an abutment portion 15 which includes the abutment surface 18 which forms an obtuse exterior angle with the upper surface of the member 17, the angle being between a 100 and 135 degrees, the aperture 14 is provided with the surface 19 which engages the surface 18. The coupling member 17 is provided with a pivotal locking member 27 which has a handle 28 and the spaced locking means 20 and 20a which as shown are cams.

Movement of the locking member in an anticlockwise direction allows the mating surfaces 18 and 19 to become disengaged by a pull on the belt. In a modification the aperture can be in the member 17 and the abutment portion 15 is on the member 10. When a single surface 19 is provided on the member 10 it can be engaged with the member 16 in only one position; when it is desired to engage the two members with the member 10 in any one of two positions 180 degrees from each other two surfaces for engaging the abutment portions 15 are provided on the member 10.

Title: Improvements in or relating to means, operated by a rise in temperature, for cutting out electrical apparatus and for effecting mechanical operations
IPC: H01H37/76
Filed: 1919-01-23
Abstract: 141,820. Dunhill, A. Jan. 23, 1919. Thermal switches, cut-outs, and interrupters.- In means for cutting out electrical apparatus and for effecting mechanical operations operated by a rise in temperature a quantity of fusible material in the form of a rod or strip is partly exposed to heat from the device to which it is attached; this rod or strip is adapted to be fed forward sufficiently to maintain a switch or other device in one positicn so long as the rod or strip is unfused. After fusing the rod may be fed forward to reset the device. As applied to an electric kettle provided with a switch having an arm f<2> held in the closed position by a spring plate h in engagement with a tongue g on the arm, and a spring tending to open the switch, the fusible element is in the form of a rod q lying in a porcelain tube n. One end of this rod abuts against a feed screw m operated by a milled nut r' on the exterior of the kettle and the other end lies against a rod d which is in engagement with the spring plate h and holds it in operation against the tongue g. A block k of copper or other heat-conducting material having a semicircular opening lying about the end of the fusible rod q is adapted to convev heat from the base of the kettle so as to fuse the end of the rod before a dangerous temperature is reached, whereupon the spring plate h frees the switch arm and the switch opens and cuts off the current. By operating the nut r<1> the rod q may be fed forward and the device reset so that the switch may be retained closed as before upon operating the turn member f<1>. This member carries an arm g<2> which engages the switch arm f<2> to close the switch and upon reverse rotation also depresses the extreme edge of the plate h to allow the switch to open under the influence of its spring, independently of the operation of the fusible device. The movable member of the switch may be arranged to slide from its ' on ' position by its own weight or by a weight attached to it. The fusible member may operate against a spring-controlled tap, valve, or the like. The tube n may have a series of longitudinal holes with a length of fusible material within each and may be rotatably mounted so that an one of these holes mav be alined with the rods m and d. Other methods may be devised for feeding forward the rod or like of fusible material so that it operates the spring or weight controlled member in the required manner.

Title: Improvements in or relating to apparatus for reading the number of electrical impulses registered in a magnetic registering device
IPC: H04Q3/00
Filed: 1957-01-17
Abstract: 805,984. Saturate reactors; automaticexchange systems. TELEFONAKTIEBOLAGET L. M. EBICSSON. Jan. 17, 1957 [Jan. 18, 1956], No. 1849/57. Classes 40 (4) and 40 (9). The number of turns on the windings in Fig. 2, are such that the amount of current required to magnetize the core Tk fully from - Br in the hysteresis loop of Fig. 1 to +Br shifts the loop of DM only one step, say from - Br to a. The windings D1-Dn are such as to be wholly magnetized when DM makes one step -n steps as the case may be. When impulsing is to start contacts k1 close. A train of impulses then operates contacts k2, k3, k5 an appropriate number of times, relay IR maintaining k4 closed for the duration of the train. At the end of each impulse rectifier LS passes a magnetizing current to the register winding DM which carries the magnetization one step from the zero value - Br, Fig. 1, nearer the value +Br. When the number stored in DM is to be read contacts k6-k8 are closed and reverse current is applied to DM. Demagnetization then occurs, the reverse current being simultaneously applied to reading windings D1-Dn, in parallel. According to the number of impulses registered in DM so an equal number of the cores D1-Dn is saturated. As soon as the core of a reading winding, say D1, is saturated the current through this winding increases sharply so blocking rectifier LH1. A current impulse then flows through the primary of transformer T1 and relay R1 to fire glow discharge tube Gl. The cathode potential of G1 then increases to block rectifier L1. As soon as DM is saturated negatively rectifier LHR is blocked, current flows through transformer TR and tube GR fires. Rectifier LR is thus blocked and current through the unsaturated reading coils is stopped. The number of impulses registered is now represented by the last of the relays R1-Rn, to be operated. The circuit is restored to normal by reversal of contact k9. Modifications. Reading may be effected by saturating the winding DM in a +ve direction, the number of unsaturated read windings then representing the number of registered impulses. The gas tubes G1-Gn, GR may be replaced by transistors.
