Filed: 1920-09-21
Abstract: 172,440. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 21, 1920. Sparking, preventing.-Two or more electromagnetic switches in series are employed to connect electric apparatus to a supply circuit, arrangements being made whereby the switches must be closed successively in a determined order and the closure of the last switch breaks the operating-circuit of the remainder. The object is to ensure that one switch shall remain in a working condition even if excessive sparking and fusing together of the contacts should take place at another switch of the series. In the arrangement shown in Fig. 1, a supply circuit 12 is connected to motors 10, 11 by means of two electromagnetically operated switches 13, 14 disposed in series and controlled by a subsidiary switch 15, a two-way push-button 16, and interlocking contacts 20, in such a manner that the switch 13 closes before the switch 14. In a modified arrangement the interlocking contacts 2 are replaced by a shunt resistance in the control circuit, which serves the same purpose. In either arrangement, after the switch 13 has been opened, as by the action of overload relays 17, 18, 19, it cannot be reclosed until the switch 14 has been opened also.

Abstract: 949,625. Suppressing vibration in floors, walls &c. TRUSCON Ltd. Aug. 3, 1961 [Aug. 3, 1960], No. 26983/60. Heading E1V. An undesired natural vibrational mode of a suspended floor, roof or wall is suppressed by selectively positioned masses contained by a plurality of cavities distributed over the structure. In one embodiment, a flat roof 11, formed by a series of spaced concrete beams Fig. 2, (not shown), supporting ceiling tiles and concrete topping, is provided with spaced horizontal tubes 15 in the concrete topping. Within each tube 15 are arranged two cylindrical weights 17 which can be connected to screwthreaded ends of tubular rods (not shown) which are introduced through opposite ends of the tube 15 whereby the weights 17 can be adjusted into positions in which an undesired natural vibrational mode of the roof is suppressed. In a second embodiment in which the roof comprises hollow blocks supported by beams and covered by a concrete topping, an undesirable natural mode of vibration is suppressed by introducing loading matter, in the form of lead plugs or shot, or gravel, concrete or grout, into the hollow spaces of some of, or even all of, the blocks. Access to the hollow spaces is effected, after construction of the roof, by breaking through the concrete topping and upper wall of the blocks selected to be filled, the concrete topping afterwards being made good by additional poured concrete. The invention is stated to be applicable to walls which could be constructed with horizontal ducts in a vertically spaced arrangement, each containing one or two horizontally adjustable weights, or which could be formed with cavities distributed horizontally and vertically so that selected cavities could be filled with loading material.

Filed: 1961-07-26
Abstract: 1,036,104. Icing detectors on aircraft. FINDLAY, IRVINE Ltd. July 13, 1962 [July 26, 1961], No. 27134/61. Heading B7W. [Also in Divisions G4 and H3] An icing indicating or alarm system for aircraft includes a transistor T, as the temperature-sensitive element connected to a transistor circuit, the arrangement being such that a warning lamp is extinguished above a first predetermined temperature (36 F.), flashes when the temperature falls to said value and burns continuously when a second predetermined lower temperature (freezing point) is reached. Operation (Fig. 1).-Above 36 F. the current between the emitter 10 and collector 12 of transistor T 1  is high, the collector voltage is close to that of positive terminal 11, T 2  is cut off, T 3  conducts, T 4  is cut off and lamp 27 extinguished. When the temperature drops to 36 F., the collector voltage of T 1  has risen to such a value that T 2  conducts and T 3 , T 4  oscillate, thus flashing lamp 27. On a further drop of temperature to freezing point, the collector voltage of T 1  has risen still further, T 2  bottoms, T 3  is cut off and T 4  remains conducting so that lamp 27 burns continuously. Testing switch 31 is normally closed and dimming resistor 28 connected into or out of circuit by a switch 30. In another embodiment (Fig. 2) the base emitter voltage of T 1  is stabilized by a Zener diode 32 fixed to resistors 36, 37 and variable resistor 38. Transistor T 5  is connected as an emitter follower. At 36 F. the collector voltage of T 1  is such that transistor T 5  is just cut off, T 2  is also cut off and lamp 43 extinguished. Between freezing point and 36 F. the collector voltage of T 1  causes T 2  to be between its bottomed and cut-off condition and acts as a grounded emitter amplifier with a gain greater than unity. The feed back through capacitor 48 and resistor 49 causes T 5 , T 2  to oscillate, thus flashing lamp 43. The rate of flashing varies so that the lamp is on for less time near 36 F. than at freezing point. Below freezing point transistor T 2  is in its bottomed condition and lamp 43 is continuously lit.
