Title: Compressed air brake
IPC: B60T15/56
Filed: 1925-02-26
Abstract: 230,077. Lambertsen, S. Feb. 29, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Fluid-pressure. -- A graduated release of compressed-air brakes is obtained by the use of an additional train pipe which, in the release position of the triple valve, is connected to the auxiliary reservoir. The additional train pipe may also be connected to the brake cylinder during a brake application. The triple valve comprises main and graduating slide valves g, a, and in the release position shown in Fig. 1, the additional train pipe L is connected through ports and passages 1 - - 5, 14 to the auxiliary reservoir G. If, after a brake application, in which the auxiliary reservoir is connected to the brake cylinder K by ports and passages 14, 17, 16, 15, 12, 10, the pressure in the train pipe F is increased for a graduated release, the triple valve moves to release position, in which the brake cylinder is connected to atmosphere through ports and passages 10 - - 6. When, however, the pressure in the valve chamber II, connected to the auxiliary reservoir by a passage 18, fust exceeds the increased train pipe pressure in the chamber I, the graduating-valve a is moved to lap position, in which the brake cylinder is cut off from the exhaust passage 6 and the pipe L is cut off from the auxiliary reservoir. In the form shown in Fig. 7, with the main and graduating slide valves in application position, the additional train pipe is connected to the brake cylinder by ports and passages 1, 11, 13, 16, 15, 12, 10, a non-return valve c being inserted in the passage 14 to prevent passage of air from the additional train pine to the auxiliary reservoir in this position of the triple valve. The passage 13 may be so small that only sufficient air is supplied through it to compensate for leakages from the brake cylinder.

Abstract: 1,044,982. Phase detectors; testing aerials. MINISTER OF AVIATION. Feb. 8, 1965 [Feb. 7, 1964], No. 5332/64. Headings H3A and H4A. Two R.F. signals of equal frequency are phase compared by applying both to a pair of phase detectors 3, 4, with the two inputs of one signal to the phase detectors relatively phaseshifted by 90 degrees, and the one or other signal modulated by a low-frequency oscillator 17. The output of one phase detector (3) is then phase-shifted by 90 degrees at the modulation frequency and added to the other phase detector output so that from the adder 7 a signal C sin (2#f 1 t + #) is derived, where # is the original phase difference to be measured, and f 1  the frequency of the modulation oscillator 17. The limited outputs of the adder 7 and modulating oscillator 17, are then applied to a phase detector 9, which produces a D.C. output indicating at 11 the phase difference #. Waveguides, strip lines or coaxial lines may be used for the R.F. sections. One R.F. signal may be that of a transmitting oscillator 1 feeding an aerial probe 2 and the other a signal picked up by a receiving probe 12 for measuring the phase shift in the electromagnetic field, radiated by the transmitting aerial, relative to that at the probe 12. The probe 12 output may be passed to the modulator 15 through an adjustable phase shifter 16. Alternatively the probe 12 may reflect back a signal via the aerial 2 to a hybrid circuit between the oscillator 1 and aerial, and its reflectivity varied by or at the frequency of the modulating oscillator; the hybrid circuit then feeding the phase detectors. The aerial and probe 12 may be interchanged.

Title: Improvements in and relating to Air-controlling Mechanism for Glass-blowing Machines.
Inventor: WHITE ALFRED ERNEST
IPC: C03B9/22
Filed: 1916-09-12
Abstract: 110,305. White, A. E., (Westlake European Machine Co.). Sept. 12, 1916 Blowing.-Relates to air-controlling mechanism for glass-blowing machines of the kind described in Specification 26,222/11 for making electric-lamp bulbs &c. The blowing-spindle is periodically connected to reservoirs of high and low pressure air by the operation of cam-actuated valves. The duct leading from the source of low-pressure air is provided with a valve 560, Fig. 7, which is opened while the blank is in the finishing-mould, an adjustable valve 542 in the duct standing partially open to retard inflow through the duct so that the pressure is applied to the blank gradually when the valve 560 is opened. The low-pressure air passes along the duct 539, past the adjustable needle-valve 542, and through a port 549 to the valve 560, which is opened by a cam-actuated plunger A<1> operating on an intermediate spring-pressed detached rod 566, which passes through a packed bearing 571, thereby admitting air through a duct 552 to the blowing-spindle. The high-pressure air is admitted to the spindle by two valves of similar construction to that shown in Fig. 7, but by the automatic closure of one of these valves, puffs of air in measured quantities are delivered, the pressure of the air being controlled by a regulator, Fig. 10, comprising a spring-pressed diaphragm 590 governing a throttle valve 609. A fourth cam-operated valve, also of the construction shown in Fig. 7, is used to put the blowing-spindle in communication with the atmosphere after each successive puff of air has been introduced into the blank. In a modification, rotary valves are used instead of reciprocating valves, sector gears on the valve-stems engaging rack-teeth on the cam-operated plungers. Specification 111,122 also is referred to.

Filed: 1966-02-10
Abstract: 1,062,392. Photo-electric control of electric motors. GENERAL MOTORS CORPORATION. Feb. 10, 1966 [Feb.26, 1965], No.5864/66. Heading G1A. [Also in Division H2] A motor has squirrel cage rotor 13, starting winding 14, and main winding 15, the initially high starting current which passes through transformer primary winding 16 generating sufficient voltage in secondary 17 to switch-on neon lamp 18. The light from the lamp reduces the resistance of photo-responsive element 20 to energize starting winding 14. As the motor approaches its running speed, the current in winding 15 decreases to extinguish the lamp 18 whereby element 20 operates to de-energize winding 14. In another arrangement, a pair of photo-responsive resistors or cadmium sulphide cells are connected in parallel with each other and in series with the starting winding of the motor. An iron-cored inductor is in series with the main winding, and is shunted by a resistor and an incandescent lamp bulb. A thermal overload relay is provided. A phase-shifting capacitance may be connected in series with the starting winding. The inductor may be tapped for selective connection with motors of different rated horse-power. In a further embodiment, the lamp is connected across tappings in the main winding in series with a backto-back Zener regulator. An internal inductor in the main winding is arranged so that the tap connection provides a different magnetic path for the tapped portion, the tapped winding having a larger voltage-drop than the remainder of the main winding under high current conditions. Ferrous wedges in the stator slots surrounding the tap portion of the coil ensure a substantially linear relation between tap voltage and current.

Filed: 1960-02-19
Abstract: 963, 697. Automatic flow control. FOXBOROYOXALL Ltd. May 19, 1961 [Feb. 19, 1960], No. 5982/60. Heading G3R. [Also in Division F2] An actuator comprises an electrically controlled coupling 3b which transmits a torque that varies in accordance with a variable electrical signal fed to the coupling. The input member of the coupling is connected to a constantly rotating electric motor and the output shaft 7b carries a lever arm 15 which positions a member 1b, such as a valve spindle, against a spring loading 12b. The electrical signal is fed to a coil 21 on an iron bar 22 which is pivoted at 23 and connected at one end by a spring 26 to the member 1b. The bar is mounted between two permanent magnets 24, 25 and carries a polepiece 28 located between limbs 29, 30 of a transformer. The transformer is connected by leads 35 to an amplifier 36, which includes a rectifier, and thence by leads 37 to the coupling 3b. In operation a small change in the current fed to :he coil 21 or in the position of the spindle 1b causes rotation of the rod 21 thereby altering the linkage between the primary winding 31 of the transformer and the secondary windings 33, 34. Such a change causes a comparatively large signal to be fed to the coupling to change the position of the spindle. Movement of the spindle also acts through the spring 26 in a direction to restore the movement of the bar 22 and hence a reduction of the signal. Such an arrangement overcomes initial forces of friction. Where the spindle is a valve spindle, the electrical signal may be provided in response to flow in a pipe in which the valve is mounted to maintain a constant flow. Specification 963,698 is referred to.
