Title: Improvements in accelerometers
Inventor: BARNES JEFFREY WALTON
IPC: G01P15/13
Filed: 1955-01-13
Abstract: 783,104. Electric measuring systems. MINISTER OF SUPPLY. Jan. 12, 1956 [Jan. 13, 1955], No. 1065/55. Class 40 (1). A linear accelerometer of the kind in which a mass 11 is constrained to move in an arcuate path when subjected to acceleration in the active direction, i.e. the direction tangential to the arc when the mass is in its zero position has in addition to the compliance in the active direction, elastic compliance substantially in the direction of the cross acceleration, whereby the path of the effective centre of mass under the influence of acceleration in the active direction is changed and errors are reduced. In the construction shown, the mass 11 is an arm which is mounted by means of a spring pivot 12 comprising four crossed leaf-springs. The arm carries the moving elements of a direct current operated force motor 13 and of an alternating current operated pick-off 14, these operate in conjunction with amplifier means, not shown, whereby there is imparted to the arm 11 by the motor 13 a restraining force proportional to the deflection of the arm 11 about its pivot under the influence of acceleration. To provide the elastic compliance substantially in the direction of the cross acceleration two equal masses 15 are secured to the ends of a single flat spring leaf 16 which is secured mid-way of its length to the free end of the arm 11. The effective mass of the accelerometer is arranged to have the same effective elastic compliance in the direction of the length of the arm 11 when in its zero position as it has in the direction in which the leaf-spring 16 extends when the arm 11 is in its zero position.

Title: Improvements in or relating to automatic control systems for aircraft
IPC: G05D1/02
Filed: 1945-01-17
Abstract: 660,552. Automatic steering control systems. SPERRY CORPORATION. Jan. 17, 1945 [May 25, 1942], No. 1465/45. Addition to 660,575. Class 38 (iv). In an automatic control system for an aircraft, wherein a control surface is actuated by an electric motor responsive to control signals which may be derived from a radio receiver as described in Specifications 660,551 and the parent Specification, the heading - controlling motor 8 is prevented from over-running by a braking effect provided by a generator 34 driven by the motor and arranged to supply a degenerative feed-back voltage over a line 221 and potentiometer arm 222 to the input of the turn signal amplifier. The generator 34 is of known type, comprising a stator winding 191 excited from an A.C. supply of the same frequency as the input or turn control signal, and another stator winding 102 which constitutes the output winding, the rotor being formed by a magnetic cylinder enclosed in a conducting shell, e.g. of copper. A portion of the generator output voltage is used to operate the bank-controlling circuit, the amount being determined by a potentiometer 213 which may be set to correspond with different air-speeds. The input to the bank control circuit is amplified by a valve 195 and detected by phase detector diodes 197, 198 to give a D.C. voltage which is used to unbalance the grids of a double modulator valve 202 to which an A.C. voltage is applied over a lead 219 from a transformer 218 connected to A.C. terminals 56<SP>1</SP>. The output of the modulator 202 is used to operate the ailerons by energizing the stator 110 of a motor 32 in a manner similar to that of the rudder control motor 8. The feed-back voltage from a potentiometer 36 corresponding to potentiometer 28 in the rudder control system is phase-detected by valves 206, 207, the resultant D.C. output being used to oppose the D.C. potential applied to valves 202. A braking effect is applied to the aileron controlling motor 32 by a generator 37 driven by the motor in a circuit over which a voltage proportional to the speed of the motor is degeneratively fed back from a generator field winding 220 connected to the primary winding of a transformer 210. Manual control of the aircraft mav be obtained by actuating a switch 63 to disconnect the system from the heading control signals of the radio receiver and short-circuit conductors 64, 65, whereupon the control signal for the heading-control motor 8 is derived from the follow-up potentiometer 28 which is geared to a manual control-knob 177, a slipping frictionclutch 175 being provided to enable the potentiometer to be rotated relative to motor 8. Motor 8 immediately responds to the output of the potentiometer circuit resulting from movement of the potentiometer from balance position, and operates to change the heading until the potentiometer is returned to balance. The control, including braking arrangements, of the elevator motor, is similar to that of the turn control.

Abstract: 1292351 Dry shavers BRAUN AG 14 Jan 1970 [14 Jan 1969] 1811/70 Heading B4B In a motor driven dry shaver, the severed portions of hair are electrostatically attracted to an electrode 31, a potential difference being created between the electrode 3 and an outer cutter 1. The source of potential is a generator in the form of a disc driven by the motor to produce electrostatic charges. Hairs protruding through the outer cutter 1 are polarized to form dipoles and when severed by an inner cutter 21, consisting of dielectrical material with or without metal cutting edges, the parts cut off are of opposite polarity to the collecting electrode and are thus attracted to it. The inner cutter may comprise a grid 210, separate blades 21 or be formed from a ceramic slotted shell 22, Figs. 4, 5. The ceramic may have an outer metal coating before slotting to provide cutting edges. The electrode 31 may be replaceable, and may have an adhesive coating or, for a fixed electrode, a removable adhesive strip to grip the portions of hair. Alternatively, either a replaceable cover or the electrode 31 itself may have honeycomblike depressions filled with adhesive material. To produce a more uniform field between the electrode and the cutter 1, the electrode may be arched towards the cutter 1. A hydroscopic substance may be placed in the area of the electric field to prevent discharge due to moisture.

An artificial respiratory apparatus comprises a device 1 for producing alternate positive and negative pressures to cause a person to respire, a valve 18, 21 for closing off device 1 from the lungs 20 when the pressure in the duct leading from the device 1 to the lungs falls below a predetermined value, and an adjustable means (not shown), e.g. a tension or compression spring, for acting on the valve to determine the predetermined value if this value is other than atmospheric pressure. For inhalation air or oxygen supplied through nozzle 4, passes to the lungs 20 via valve 9 and ducts 15, 19, valve 7 being closed. When the pressure in the change-over box 2 reaches a predetermined maximum, diaphragm 12 moves to the left closing valve 9 and valve 7 opens so that air from nozzle 4 withdraws air from the lungs and change-over box 2 and exhausts through valve 7. If the pressure in the duct leading to the lungs gets too low before the apparatus is changed over to supply air to the lungs, the diaphragm 18 is pressed against member 21 so that the lungs are not subjected to an undesirably low pressure. The valve for closing off the device 1 from the lungs may comprise a flexible tube or a chamber with one flexible wall.
