An ice eliminating system for an aircraft comprises a plurality of inflatable units 3 each associated with a distributer 18 adapted to connect the units to either the pressure supply line 15 or the suction line 8, being under the control of the timer 20. The suction line 8 is connected to pump 6, which feeds high pressure air to the valve 10, adapted to direct the air to the supply line 15 or the atmosphere, and which is also under the control of timer 20. The valve means 10 may be as described in Specification 646,737. The timer is shown in Fig. 2, wherein the shaft 35 driven by the electronic timing unit 21, which may be as described in Specification 655,437, [Group XL (c)], operates two contact arms 36 and 37, respectively controlling through contacts 36A-G and 37A-G, the distributers 18 and valve 10. The cycle of operation is that first contacts 36A and 37A are made, the latter operating solenoid 33 which operates valve 10 to supply fluid to the line 15. On contacts 36B-G and 37B-G, the fluid supply is maintained, and solenoids 39 operate distributers 18 to inflate each unit 3 in turn. For the remainder of the cycle (contacts 36 H-L and 37 H-L), the pump output is diverted to atmosphere, and all units 3 are deflated. By this arrangement, pump 6 works at high load for only part of the cycle, and a lower operating temperature is possible. In an alternative embodiment, only one contact arm is used to operate both sets of contacts, and the contacts 37A-G take the form of one strip, which may be so arranged that contact is made with it before the arm comes to contact 36B, and ends when the arm leaves contact 36G. The size of contacts 36A-G may be chosen so that contact is made for a period proportional to the cubic capacity of the corresponding units 3. Specifications 548,138, 621,490, and 621,497 also are referred to. Reference has been directed by the Comptroller to Specifications 548,138, 621,490, 621,497, 646,737 and 655,437, [Group XL (c)].

Title: A device for indicating variations in the thickness of magnetic coatings
IPC: G01F1/56
Filed: 1954-01-26
Abstract: 758,541. Electric thickness gauges. PYRAL. Jan. 26, 1954 [Aug. 29, 1953], No. 2324/54. Class 37. The thickness of a magnetic coating on a strip of paper or plastic material is determined by passing the strip through a gap in a magnetic circuit whose reluctance is measured. In one embodiment (Fig. 3) the coated tape passes through the gap in the core N1 of a coil L1 forming with parallel capacitor C1 the tuned circuit of an oscillator H1 whose output is mixed at M with that from a fixed-frequency oscillator H2. With the correct thickness of coating on the tape the frequencies of H1 and H2 are equal, but with variations in thickness an audible beat frequency is produced which is amplified at A to be shown at I and heard from a loud-speaker HP. In a modification the audible beat frequency is produced against a harmonic of the resonant frequency of the measuring circuit L1, C1. In another embodiment (Fig. 4) the output of the tuned circuit L2, C2, wherein the core N of coil L2 has the airgap through which the coated tape is passed, is compared in a frequency discriminator circuit with that from a fixed frequency oscillator G whose tuning coil L1 is loosely coupled with L2 through the core N. The voltage across each half of coil L2 is added vectorally to the voltage from oscillator G to give two equal magnitudes when the frequencies are the same, but different values when the frequencies are different. These voltages are rectified at D, D<SP>1</SP> and applied in opposition to a valve-voltmeter VE to give a reading whose sign and magnitude is therefore indicative of the direction and magnitude of the variations in thickness of coating producing the frequency differences. In a further embodiment (Fig. 7, not shown) the coil whose core contains the measuring air-gap constitutes one arm of an A.C. bridge circuit, the opposite arm being a similar coil with adjustable air-gap core, and the other arms comprising equal resistors. The unbalance current in the bridge indicates the variations in thickness of magnetic coating. Specification 714,881, [Group XX], is referred to.

Abstract: 756,024. Photo-cell circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 18, 1952 [Jan. 30, 1952], No. 2506/52. Class 40 (3). [Also in Group XXXV] To reduce effects due to the difference between pull in and drop out voltages of a relay L, over which a load 1 is directly controlled, say, by a photo-electric cell P, the load contacts of the relay are also arranged to control a circuit influencing the current in the relay coil. As shown, the relay has normally open load contacts and its coil is in series with a variable resistor R2 which is so adjusted that with the cell P unexcited, the relay is on the verge of pulling in. A low excitation of the cell will then cause the relay to operate, thereby energizing the load which now diverts current from the coil circuit on account of a common series resistor R1, which is so adjusted that the coil current drops nearly to the pull out value. A swamp resistor R3 may be provided in the load circuit to prevent hunting of the system when the load 1 is of variable resistance, such as a lamp filament. In a modified arrangement using a relay having normally closed contacts, the load, relay coil and the contacts are all in series, the control current passing direct to the coil through a suitable resistor.

Filed: 1927-01-29
Abstract: 275,087. Stopford, H. Jan. 29, 1927. Springs, arrangement of; guiding vertical play; axle attachments.-In a power-vehicle, move,- ment of the wheel axles longitudinally of the vehicle is stopped only by abutments provided at the front and rear ends of the frame, so that the driving thrust of the rear wheels is transmitted to the front of the frame and braking thrust of the front wheels is transmitted to the rear end of the frame. In the form shown in Figs. 1 and 3, the front and rear axles 13 14 are coupled by members 17 pivoted at 18 to lugs 19 on the axles, the members 17 being preferably in two parts connected at 24 so that the axles may tilt independently, without straining the coupling members. The front and rear suspension springs 1, 2 are pivoted at their front and rear ends 7, 9 respectively to the frame, their other ends being connected to the frame by shackles. The connections between the springs and axles comprise pairs of plates 11, 15 on the springs and axles, the axle plates 13 being slotted at 20, 21 to receive the clamping bolts 12 of the springs. The slots are arranged so that when the coupled axles move forward relative, to the frame the rear ends of the slots 20 engage the front clamping bolts 12, the rear ends of the slots 21 being clear of the rear bolts 12. Driving thrust is thus transmitted to the front springs and thence to the frame, and similarly braking thrust of the front wheels is transmitted to the rear end of the frame. The connection between the two parts of the member 17 comprises nipples 22, Fig. 6, screwed on the adjacent ends of the parts and having flanges 23 engaged in recesses in a two-part sleeve 24 held, together by bolts 26. The nipples are free to rotate in the sleeve 24 and are held in adjusted position on the members 17 bv lock-nuts 25. In the modification shown in Fig. 4, the provision for relative movement between the, axles and frame comprises slotted connections 32 between the springs and the frame, the driving and braking thrust being taken by abutments 33 at the front and rear ends of the frame respectively. The axles preferably carry rollers 34 for engagement with the abutments which may be adjustable along the frame and have their lower ends curved inwards beneath the axles. The curved ends of the abutments may be adjustable in height. In a further modification, the front and rear axles are not coupled but have rearwardly and forwardly extending thrust members guided to move longitudinally and engage abutments such as 33, Fig. 4. In each arrangement both the torque tube 5 and the transmission shaft are telescopic and do not transmit the driving thrust.
