Title: Improvements in or relating to suction nozzles for vacuum cleaning apparatus
IPC: A47L9/04
Filed: 1936-04-20
Abstract: 462,870. Vacuum - cleaner heaters. ELECTROLUX, Ltd. April 20, 1936, No. 11251. Convention date, April 20, 1935. [Class 8 (i)] The beater 21 of a vacuum cleaner is connected with or constituted by a movable diaphragm 18 dividing the nozzle into parts connected by an opening in the diaphragm or a connection controlled by a valve 27. The stem of this valve is connected to a second diaphragm 33 within an upper compartment of the nozzle, and a passage in the stem connects the underside of this diaphragm with atmosphere, while the upper side communicates with the suction space 30 above the beater diaphragm. Suction raises the upper diaphragm and closes the valve ; the beater is then raised until at the end of the stroke it parts from the valve, when the inlet of air raises the pressure above the upper diaphragm, allowing the valve to fall under spring pressure and the beater to be pressed downwards by leaf springs 25. When running over a hardwood floor, the flow of air gives sufficient pressure above the upper diaphragm to keep the valve permanently open, stopping the beating action. In a modification, the valve stem is carried merely by a spring, and the valve may be locked in open position by depressing and turning the stem, causing engagement of a pin in a groove. In a further modification, the valve lies above the diaphragm and is carried by a diaphragm subjected to atmospheric pressure and vacuum alternately, under the influence of tappet valves actuated by the beater diaphragm.

Title: Improved flying machine for vertical and horizontal flight
IPC: B64C23/00
Filed: 1926-04-29
Abstract: 251,645. Noeggerath, J. E. April 29, 1925, [Convention date]. Void [Published under Sect. 91 of the Act]. Aeroplanes; helicopters; landweels; fluids; arrangement of; fuselages; planes, arrangement of; propelling; steering, balancing, and regulating altitude.-Comprises several constructions designed to enable an aeroplane to rise vertically under the power of the ordinary screw propeuer. In one form of the invention an otherwise ordinary aeroplane is designed so that when it rests on the ground, the propeller shaft makes a large angle with the horizontal, and is provided with specially large steering surface. The initial tilt of the propeller shaft is obtained by making the undercarriage, which may be pivoted to the fuselage, abnormally tall or by providing a two part fuselage the rear part of which can be withdrawn into the forward part as shown in dotted lines in Fig. 3. Springs may be arranged between the two parts of the fuselage. In the case of sea-planes the floats are pivoted to the undercarriage so as to maintain this horizontal position. In the remaining arrangements, passengers are carried in one or more main hulls 11, 16, 31 which remain horizontal during flight, the engine unit and supporting surfaces being capable of angular movement with respect to these. In a monoplane, Fig. 4, the engine hulls 12, 13 and the three part wing 14 are secured to a shaft 15 rotatable in the passenger hulls 11. The propellers may overlap each other or may be further apart and run in the same direction. In a tri-plane, Figs. 6, 7, with the upper plane nearer to the middle plane than the lower one, the planes and engine hulls are carried by an axle 19 rotatable in bearings provided above the main hull 16. Steering surfaces 22 - 24 are provided on all the hulls and the wings are provided with ailerons 25 connected in pairs for adjustment in opposite directions. In a further arrangement, Figs. 9, 10, the planes 26 on either side and the engine hulls are separately adjustable relatively to the main hull 31 and to each other. Ribs 32, 33 are provided on the engine hulls and the planes to minimize lateral air currents. Each hull is provided with a rudder and elevator and the planes are furnished with ailerons 38. The forward end of the main hull is provided with a surface 40 which may itself be adjustable and carries an adjustable surface 41 for balancing during vertical motion. In all the forms described the relative motion between the engine hulls and the wings and the main hull may be obtained by adjusting the ailerons and the steering surfaces. To minimize gyroscopic action the propellers are braked while this motion is taking place. A brake is provided for locking the parts in the desired relative position. Fuel and lubricant tanks and the pilots seat are preferably mounted in fixed positions relatively to the landing carriage which may be adjustable with respect to the main hull.

Title: Automatic control apparatus for aircraft
IPC: G05D1/04
Filed: 1947-04-28
Abstract: 637,188. Automatic attitude and steering control systems for aircraft. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. April 28, 1947, No. 11351. [Class 38 (iv)] In aircraft control equipment comprising means for banking the aircraft about a selected angle relative to a roll datum and applying a corresponding rate of turn in azimuth, means including a side-slip detector is provided correcting both the angle of bank and the roll datum upon side-slip occurring due to wander of the roll datum. In Fig. 1, the aircraft is banked about a roll axis 14 by rotating a normally horizontal platform 11 to generate from a roll gyroscope 5 an A.C. voltage proportional to the rate of turning of the platform, this being applied to an aileron servomotor 19 through a high gain amplifier 21 in series with an opposing feedback voltage reducing the input substantially to zero from a generator 22 driven by the motor so that the aircraft rolls at a rate and by an amount to maintain the platform horizontal. At the same time a tangent potentiometer 24 applies a signal through a similar system to the rudder, servomotor causing the aircraft to turn under the applied bank at a rate such that the voltage' from a rate-of-yaw gyroscope 1 cancels that of the potentiometer and at normal cruising speed no side slip occurs. At angles of bank above 3 degrees a battery connected wiper arm 54 on the platform gimbal 13 moves from an insulated insert 56 to energize through a contact 55 a relay 51 and operate to dotted position switches 52, 53 so that a pendulum side-slip detector 25 output in series with the yaw gyroscope 1 monitors the rate of turn. Below 3 degrees, however, the insert 56 insulates the arm 54 so that the relay 51 and switches are de-energized and the side slip voltage, if any, is applied in series with the roll circuit to correct the angle of bank. Side-slip due to wander of the bank datum level is therefore prevented. In a modification, the side-slip detector output is applied to the roll control circuit whatever the angle of bank and correction made in the yaw control circuit for varying speeds of the aircraft by varying the output of the tangent potentiometer by a further potentiometer operated by a pitot pressure tube. The generator 22 and electric motor 19 may be of the two-phase hysteresis type described in Specifications 576,248, 576,249 and 576,351 respectively. Specifications 611,037 and 617,240 also are referred to.
