Abstract: 585,652. Hair curlers. BEDACK, M., and BEDACK, E. Dec. 11, 1944, No. 24787. [Class 131] A curler for cold permanent waving comprises a bobbin-shaped body 1 with an axial cavity for the securing of the knotted end of a length of string, the bobbin having open slots at both ends for guiding and gripping the string when it is drawn taut over the coiled lock of hair. A plug 2 is inserted to form a compartment 3 housing the knot 6 on the string 4 which passes axially out of the curler. Four radiating slots 7 at each end of the curler act as guides for the string 4. At the plug end they are larger than the diameter of the string and at the other end are smaller and grip the string. A shoulder 5 may be provided on which the plug rests. In a modification the compartment is formed by boring almost the entire length of the curler, the string passing through a narrow opening in the unbored part and inserting an elongated peg which closes up the boring except for the compartment housing the knot.

Title: Aircraft Navigation System
Inventor: PERKINS EARL S
IPC: G01C21/20
Filed: 1967-05-31
Abstract: 1,194,422. Radio navigation. BUTLER NATIONAL CORP. 31 May, 1967 [31 May, 1966], No. 25203/67. Heading H4D. In an aircraft navigation system comprising indicating means for indicating changes in aircraft position the response rate of the indicating means (i.e. the maximum rate at which the indicating means can indicate changes in the position of the aircraft) is, in one aspect of the invention, modified such as to decrease and increase as the distance to a navigation station increases and decreases respectively, and in another aspect of the invention, is controlled as a function of the speed of the aircraft. The response rate modification may be achieved by an integrating circuit of adjustable time constant in the path of a V.O.R. receiver output to an indicator, or by controlling an electro-mechanical system coupled to the moving index of an indicator. The indicator may be an angularcourse-deviation moving-coil meter, or a twinpointer linear displacement indicator fed by rate-limited resolved components R, #, where R is the range to, and 0 the bearing relative to, a VORTAC station. In one embodiment, Fig. 5, the rotor 65 to 67 of a synchro differential mechanism is controlled from V.O.R. receiver 32. The rotor output winding 78 of transformer 74 is connected to the control winding 81 of servomotor 82, rotor 84 of which is coupled to ball-and-disc integrator 85. D.M.E. receiver 87 is connected to control windings 87 of servomotor 88, the rotor of which is coupled to integrator 85. In another embodiment the charging time of a capacitor is controlled from the output of a D.M.E. receiver so as to provide pulses of one-cycle A.C. with a spacing varied as a function of range to the VORTAC station; the pulses energize a servomotor coupled to the pointer of a course deviation indicator, Fig. 6 (not shown). A further embodiment incorporates a potentiometer coupled to a D.M.E. receiver, the potentiometer being connected (electrically) to an A.C. tachometer generator, Fig. 7 (not shown). One form of response rate modifying circuit comprises a pair of transistors 121, 126, Fig. 8, transistor 121 representing an effective short-circuit for signals of one polarity and transistor 126 a short-circuit for signals of the opposite polarity. The charging or discharging of capacitor 131 for an input signal shown in full lines in Fig. 8A yields an output signal indicated in broken lines. Ganged resistors 124, 125, or conjoint potentials E1, E2, may be varied from a D.M.E. receiver or from a speed sensor. In the system of Fig. 10, an indicator 52A has a meter movement 291 controlling the vertical displacement of index 53A and the meter movement is connected to a detector 286 through an integrator 292 and an integrator 298 is between meter movement 297, controlling index 54A, and a detector 284. Resistor 302 in integrator 298 may set the response rate in accordance with maximum aircraft speed. The intersection of indices 53A, 54A represents a predetermined way point and element 55A represents the aircraft.

Abstract: 600,111. Furnaces. BABCOCK & WILCOX, Ltd., and SPARKS, C. H. Oct. 1, 1945, No. 25414. [Class 51(i)] In a furnace wherein the fuel is fed to the grate 8 by a sprinkler 6, the ash is removed to a pit 10 by a transverse drag member 13 which is so shaped that, during its movement towards the rear of the grate, a cleaning action is exerted on the fuel bed, and when moving towards the front of the grate, a dragging action is exerted on the ashes at the bottom of the fuel bed. The member 13 is formed with a slightly inclined rear face 14, and a steeply inclined front face 15, and is dragged over the grate by a chain, or chains, 16 which runs in a groove in the grate, the chain substantially filling the groove and sealing it against entry of ash. The chain is trained over sprockets 17, 18 and is driven by a chain 19 driven by a reversible electric motor through reduction gearing. The member 13 is normally housed beneath the arch 9. When ash is to be removed it is moved to the rear of the grate and is then returned to the front. When the ash is positioned over an independently controlled air supply compartment 12, the member 13 comes to rest to permit the ash to be burnt completely. The member 13 then moves further to the front and pushes the ash into the pit 10. The air pressure in the compartment 12 is greater than that in the main compartment 11. The reversal of the motor and its stopping and starting when the ashes are above the compartment 12 may be automatically effected, and an indicator, showing the position of the member 13 on the grate, may be provided. In the case of a wide sectionalized grate, each section may have a separate member 13, and the members may be operated simultaneously or separately. The member 13 may be moved from the rear to the front of the grate by an endless chain driven unidirectionally, openings at the ends of the furnace for the passage of the member 13 into and out of the furnace, and sealing means for the openings, being provided.
