Filed: 1929-11-28
Abstract: 336,147. British Thomson-Houston Co., Ltd., (Assignees of Blume, L. F.). Nov. 28, 1928, [Convention date]. Transformers. - A transformer is provided with an auxiliary winding in which some of the turns are arranged on a part of the coil where the main and leakage fluxes are in the same direction and the remaining turns are arranged on a part of the core where the main and leakage fluxes are in opposition, the two groups of turns being connected so that their voltages are in opposition thus providing a resultant voltage proportional to the leakage flux which is utilized in a measuring instrument which may be calibrated to indicate the load on the transformer or the voltage of the main windings. Figs. 1 and 3 show respectively how the groups of turns 15, 16 of the auxiliary winding may be arranged to provide an indication of load current in shell-type and core-type transformers having main windings 13, 14. The directions of the main and leakage fluxes are respectively indicated by broken and full-lines in Fig. 5. The Specification also gives information as to the relative proportioning of the numbers of turns in the auxiliary winding groups necessary to obtain an indication of the voltage of the main windings.

Title: Improvements related to speed responsive devices
IPC: G05D13/08
Filed: 1961-10-18
Abstract: 1,006,079. Turbines. GARRETT CORPORATION. Oct. 18, 1961 [Oct. 19, 1960], No. 37445/61. Heading FIT. [Also in Division G3] A speed governor, e.g. for an air turbine, has a rotatable mechanism 10, Figs. 2, 3, carrying flyweights 37 arranged to be moved radially outwards away from one another by centrifugal force against the action of spring steel members 35, the flyweights acting as a valve to control the rate of flow of a control fluid through an orifice 20 which opens on to the axis of rotation of the mechanism 10. A turbine 12, Fig. 1, has an inlet conduit 13 for fluid under pressure, a valve 14 being provided in the inlet conduit, which valve is opened and closed by a pneumatic actuator 15. Fluid under pressure is supplied to the actuator from the inlet conduit 13 through a conduit 16, and as long as pressure is applied to the actuator the valve 14 will remain open. However, the pressure on the actuator is reduced by bleeding fluid through the orifice 20, via a conduit 17, at a rate controlled by the mechanism 10, which is mounted on an extension 11, of the turbine shaft. The mechanism 10 comprises a yoke 30 provided with two arms 31 to which is fixed a rectangular spring steel frame 32. This frame provides the spring steel members 35 carrying the flyweights 37 which abut one another when the turbine shaft is stationary. The orifice 20 is positioned close to the faces 42 of the flyweights 37 leaving a small space 43 the size of which is adjustable by the use of shims 22. As the turbine shaft is rotated, the flyweights 37 will separate at a predetermined speed of rotation forming a passage therebetween allowing fluid to escape through the orifice 20. The orifice 20 is larger than a restriction 24, Fig. 1, in the conduit 16 so that the pressure on the actuator 15 will be decreased, and this will close the valve 14 to reduce the fluid flow to the turbine. The loading of the spring members 35 may be adjusted by the use of screw threads 40, Fig. 3, or shims 41 or both. In place of the flyweights 37, a single spring and flyweight may be used, or depending on the design of the turbine, the movement of the flyweights may be arranged to close rather than open the fluid orifice.

Abstract: 864,294. Controls on handlebars. ZAVODY 9. KVETNA NARODNI PODNIK. Nov. 5, 1959 [Nov. 7, 1958], No. 37603/59. Class 136(1). A control device for the carburetter of a motor vehicle has-the choke cable 14 attached to a plug 8, slidable in the end of the handle- 'bar tube 2, which is moved outward to a position where it is secured by twisting a grip 1 in the throttle-closing direction and is released by twisting the grip through a predetermined angle in the throttle-opening direction: The throttle-eable 3 is secured in a runner 4 which is moved along a longitudinal groove 6 in the handlebar 2. by a screw-thread 5 on the inside of the grip 1. The plug 8 is located in the groove 6 by a lug 11 and is held inwards by a spring 10. When the throttle is fully closed by twisting the grip the runner 4 abuts a stop 7. Further twisting in the same direction causes the grip 1 to ride outwards over the lug 5 to push against the shoulder 9 and carry the plug 8 out to the position shown in Fig. 2, where it is secured by a spring and plunger 12 which rides out against the end of the handlebar tube 2. Rotation of the grip in the opposite direction brings a lug 13 inside the grip into contact with the plunger 12 to depress it against its spring, thereby allowing the plug 8 to re-enter the tube 1, pulled by the spring 10.

Abstract: 1397597 Electromagnetic relays AMERACE ESNA CORP 11 Aug 1972 [30 Aug 1971] 37671/72 Heading H1N [Also in Division F2] A time delay device for use with a relay or like apparatus having an actuator which is movable between two positions is arranged selectively to provide a timed interval between the departure of said actuator from either one of its positions and the performance by said device of a desired event. As shown the timedelay device 10 comprises change-over snapacting contacts 104 carried on a member 98 indirectly connected to a diaphragm 122 separating two air chambers 118, 120 and urged in one direction by a spring 142. The housing 14 of the device 10 has dovetail tongues on each end for selective mating co-operation with dove. tail grooves on the end of a relay 12 from which an actuator rod 70, connected to armature 56, protrudes. A cover 36 slidingly closes the other end of housing 14. An E-shaped sliding member 72 is carried on two ports 74 and has T- shaped slots 88 in its outer limbs 80 and 82 for selective engagement with a flange 90 on rod 70. Its central finger 92 engages with lost motion a lateral shoulder 94 on a member 96 which is connected to contact-carrying member 98 with some play taken up by a spring 172, and to diaphragm 122 with some play taken up by a spring 132. Holes 130 are provided in diaphragm 122, and the surface 140 of member 96 engages a resilient annular member 138 to form a valve between air chambers 118 and 120. Spring 132 allows this valve to open when member 96 is urged in one direction (to compress spring 142) and hence diaphragm 122 does not impede its movement, whereas return movement due to spring 142 is restricted by compression of air in chamber 118 which is connected to chamber 120 via a throttling passage under control of a knob (162, Figs. 1 and 5, not shown) whereby the speed of return and hence a desired time interval is established. The spring 172 allows a rapid change-over of contacts 104 without prolonged reduction of contact pressure near their dead-centre condition. The timing device 10 can be fitted to relay 12 as shown to provide an adjustable time-delay between the opening of contacts 54, 48 and change-over of contacts 104; or can be readily inverted to provide the delay following closure of contacts 54, 48.
