Title: Improved rain or spray dispersing means for use in conjunction with transparent windscreens of aircraft, watercraft and other vehicles
Inventor: TOMS CHARLES FREDERICK
IPC: B60S1/52
Filed: 1963-02-22
Abstract: 1,070,181. Windscreen cleaners. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. May 7, 1964 [Feb. 22, 1963; Aug. 16, 1963], Nos. 7335/63 and 32574/63. Heading A4F. The outer surface of a window or windscreen in an aircraft, ship, or other vehicle is insulated from rain water and spray by streams of air or other gas directed approximately parallel to the surface and emanating from apertures in arms 11 of a rotor. The apertures may comprise slits so arranged that the gas issuing therethrough causes rotation of the rotor. Additional slits direct gas towards the window or windscreen surface for dispersing any water thereon. To ensure free movement of the rotor in icing conditions an electric heating element may be incorporated in the rotor hub mounting or hot air may be supplied to the rotor, heated e.g. by a heater in the air supply duct 16. For cleaning the window or windscreen in dry atmospheric conditions liquid solvent may be fed to the inside of each rotor arm. Tip jets (not shown) may be provided at the extremities of the rotor arms to assist rotation. Means may also be provided for moving the rotor to one side of the window or windscreen when not in use. The rotor may be used in conjunction with nozzle or nozzles arranged in the nose of an aircraft for discharging air to break up large raindrops into small droplets.

In a slow break electric switch, for use particularly in A.C. circuits, by depressing one end of a rocker 1, a turned-down end 10 of a floating, bridging contact member 8 is moved into a pocket 11 in the switch base 3, the member 8 is rotated so that the main contact end 13 is moved away from a stationary contact 22 and finally, when the rocker is in its " Off " position, the end 10 engages a second stationary contact 21. The member 8 is biased against the contacts 21, 22 by a compression spring 17 located in a pocket 18 in the switch base 3. The pocket 11 limits lengthwise movement of the member 8 and the end 10 determines the size of the contact gap 12, Fig. 3 (not shown). The member 8 may be of bi-metal with the ends inlaid with silver, and the contacts 21, 22 are of silver. Stops 6, 7 in the form of pillars of resilient material, limit the rotation of the rocker 1 and reduce the noise of the switch. A two-way switch may be provided by putting two switches side-by-side, Figs. 7, 8, (not shown), or a one-way switch may be made in a two-way switch housing by mounting a spring, to take up the free travel of the rocker, in the empty casing.

Filed: 1942-06-05
Abstract: 554,781. Gauging screw-threads. HERBERT, Ltd., A., and HUGO, L. J. June 5, 1942, No. 7664. [Class 106 (ii)] [Also in Group XXII] For facilitating the operation, an electric motor drives a rotatable member 15 which is axially movable and adapted to hold the gauge 11, while a switch is operated by this movement of the member to control the motor. The motor drives through a belt a pulley 33 loose on the shaft 15 and pressed by a spring 36 located between a cap 37 and the pulley boss 35 against a friction washer 39 between the boss and a ring 40 fast on the shaft. The other end of the shaft is provided with a bevel-closing chuck 13, 14, 16 for gripping the stem 12 of a plug screw gauge 11. In the middle, the shaft carries a ball bearing 18, the outer race 22 of which is grooved to receive a spring-pressed pin 23. In use, the operator places the work on the gauge 11 to the extent of a thread or two and then pushes the shaft axially when a contact 24 is made to start the motor which drives the shaft to screw the gauge into the work. If tight, the pulley 33 slips and the operator then moves the shaft in the opposite direction so that the other contact 24 is made to reverse the motor. The same procedure is followed when the whole length of the screw is gauged.

Abstract: 720,605. Builder motions in spinning frames. VELLA, L. March 28, 1952 [May 26, 1951], No. 7998/52. Class 120 (2). A supporting device for the thread guides in a ring spinning frame comprises a plurality of guide tubes 3 closed at the lower ends, disposed parallel to the spindles 25 and fixed to the ring rail. 2 at the rear of the spindles, a supporting rod 4 slidably mounted in each tube, a cross piece 1 fixed to the top of said rods carrying the thread guides 5 and downwardly projecting supports 8 carrying at the lower end thereof a horizontal rotatable shaft 10 having separators 11 attached thereto, and angle pieces 15 attached to the cross piece 1 which at the lower extremity of the thread guide position rest upon stop members 9. The stop members 9 are slidably mounted in guides 16 and may be raised by ropes 19 passing over pulleys 18. A spring 6 is disposed between the rod 4 and the bottom of the guide tube 3, and at the commencement of the winding operation this spring is extended, Fig. 3. During the vertical movement of the ring rail 2 a position is reached when the spring 6 is fully compressed and subsequent vertical movements cause the rods 4 to participate in the building motion, thus ensuring a constant distance between the thread guides 5 and the ring rail 2. The guide member 16 is attached to the frame 26 carrying the drawing rollers and carries fixed stop members 13 and pivoted stop members 14, Fig. 7. After the cop has been built the members 9 are raised by the ropes 19 raising the rods 4. Lugs 12 extend from the shaft 10 displace the members 14 and co-operate with the members 13 to tilt the separators 11 to facilitate removing the cops. In the return movement of the member 9 the lugs co-operate with the members 14 to restore the separators to a horizontal position.
