Title: Improvements in electric motors
IPC: H02K57/00
Filed: 1921-01-10
Abstract: 157,262. Traun's Forschungslaboratorium Ges., H. O. July 15, 1919, [Convention date]. Influence machines.- An electric motor for alternating - current of high frequency comprises a rotor and stator each composed of condenser surfaces. In the arrangement shown in Fig. 1 current is led to the rotor condenser surfaces 3, 3a, 4, 4<a>, through a commutator and brushes. The stator 1 and commutator brushes are connected through a coupling 9 to an oscillatory circuit. Additional stator surfaces 11, 12 earthed at 13 are provided for starting and rotor surfaces are preferably formed of wire or ribbon wound into a flat spiral as shown in Fig. 4 and embedded in insulating material. With such a construction of the condenser surfaces a multipolar motor may be constructed as shown in Fig. 5, current being led to the stator only. The stator surfaces 1, 2 are connected together through an inductance 10 and similarly the stator surfaces 3, 4 through an inductance 9 coupled with the inductance 10. No iron is used in the construction of the motor. The Specification as open to inspection under Sect. 91 (3) (a) describes other modifications. In one modification the winding for the stator surfaces is in the form of a Gramme ring with the different sections of the winding connected together through condensers. In another modification the stator and rotor each comprise a series of condensers 1-16, Fig. 8 (Cancelled), the condenser surfaces being in the form of flat spirals. The rotor and stator are connected in parallel to the supply circuit and regulation is effected by displacing the brushes or by introducing an ohmic resistance between the brushes and the stator leads. The spirals in adjacent pole surfaces are wound in opposite directions. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or connected with Screw Milling Machines.
Inventor: MELMORE WILLIAM MORTIMER
IPC: B23G1/32
Filed: 1918-01-21
Abstract: 121,839. Melmore, W. M. Jan. 21, 1918. Lathes.-In a screw-milling lathe, the feed motions, return motions, or both motions, of the work-holding chuck 1, and the cutter 11, are automatically controlled and operated from a cam shaft 16, preferably actuated through a one-revolution clutch mechanism 40 controlled by a handlever 44, and driven by spur gears 13, 12, and belt pulleys 17. Through a single revolution of the cam shaft 16, and by gears 14, 15, the mandrel 2 with the chuck 1 is given rather more than one complete revolution, and is at the same time fed longitudinally by the interchangeable screw 30 and nut 20. The rotating cutter 11 is fed into position longitudinally by a cam 50 engaging a roller 52 on an adjustable stem 54 carried by the slide 7, and transversely by a cam 56 engaging a roller 57 on the stem 58 carried by the headstock 8. A cam 60 then locks the slides in position through an eccentric lever 61 and a locking bolt. At the same time, a weight 37 on a strap 38 carried by the free-wheel drum 18 loose on the spindle 2, is raised by a chain 33 passing over pulleys 34, 31, the latter of which is connected to the shaft 16 by an automatically disengaging pin device 27, 28, 29 when the weight has been lifted. The cams 50, 56, 60 then allow the cutter 11 to be retracted by springs or weights, and a cam 24 acting on a spring-pressed lever 23 on the clamping-screw 22 of a split brush 5, allows the nut 20 to turn under the influence of the weight 37 and free-wheel parts 19, 18, thus allowing springs 47 to return the spindle 2 longitudinally to its original position. The screw 22 is then re-tightened and the shaft 16 de-clutched in readiness for the next cycle of operations.

Title: Improvements in or relating to circuit arrangements for the generation of frequency modulated oscillations
IPC: H03B5/28
Filed: 1954-01-15
Abstract: 754,216. Frequency modulation. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 15, 1954 [Jan. 19, 1953], No. 1261/54. Class40(5). Frequency modulation of an oscillator whose mean frequency is determined by a phase shift network comprising resistors and either capacitors or inductors is produced by adding to the feedback loop an amplitude modulated voltage in quadrature with the feedback voltage at that point, obtained from a ring modulator. In Fig. 2 the oscillator comprises a valve 27 R-C coupled to a valve 28 with anode load inductively coupled at 31 to a Wien bridge 32-35 from a tapping of which a lead 36 is coupled back to the grid of the first valve 27. Also, from across tappings 54, 55 of the bridge a voltage adjusted to be in quadrature with the feedback voltage to the valve 27 is applied through cathode followers 57, 58 in push-pull to a ring modulator 43-46 with balanced output across potentiometer 53 amplitude modulated by a signal source 47 and added, through lead 42 and resistance 39, to the output feedback voltage to valve 27. The oscillator is hence frequency modulated by the signal which may be a frequency shift telegraph signal 47. The resistance 39 may be a voltage dependent incandescent lamp to stabilize the output amplitude at 50. The network 32-35 may be replaced by a capacitor in series with the parallel combination of a resistor and a resistor and capacitor in series, or by a bridged T-network. In a modification the first oscillator valve anode is back coupled to the control grid through a cathode follower and R-C network, and part of the central shunt resistor has injected across it an amplitude modulated quadrature voltage from a ring modulator energized by carrier from a cathode follower output stage of the oscillator.

Title: Improvements in speed regulating means for internal combustion engines associated with arc welding plant
IPC: F02D1/00
Filed: 1949-01-19
Abstract: 660,153. Regulating. BOWLER, H. P., and SIDNEY, D. L. Jan. 10, 1950 [Jan. 19, 1949], No. 1531/49. Class 7(vi) The speed of an engine driving the generator of an arc welding plant is controlled by a bellows 12 operated by pressure fluid under the control of a valve 9 actuated by an electromagnet 7 having its energizing coil 8 in the welding circuit. For a Diesel engine the bellows 12 is connected to the control rod 15 of the injection pump 3 and the pressure fluid comprises fuel oil supplied by a pipe 22 from a pipe 19 through which a feed pump 2 supplies the pump 3. During welding the valve 9 is raised to an upper seat 10 to cut off the pressure from the pipe 22 and to release the pressure in the bellows through a pipe 23 leading to the fuel tank 1, whereby the bellows collapses and the rod 15 is moved to increase the engine speed to its normal load value. When welding ceases, the valve 9 drops to its seat 11 and the pressure from pipe 22 expands the bellows 12 to reduce the engine speed, the rate at which this occurs being controlled either by a valve 5 in the pipe 22 or by a dash pot 17. The bellows 12 may alternatively control an air or mixture throttle valve and, if the tank 1 is high enough, the static pressure head thereof may be used to uperate the bellows 12; alternatively it can be operated by the lubricating oil pressure.

Filed: 1926-01-19
Abstract: 246,829. Soc. du Film en Couleurs Keller-Dorian. Jan. 30, 1925, [Convention date]. Drawings to Specification. Colour photography.-In the process wherein a sensitive film having its rear side covered with lenticular elements is exposed in conjunction with a colour selecting filter associated with the objective of the camera. (1) the lenticular elements are constituted either by lines of contiguous semi-cylindrical excrescences arranged so that the troughs between the excrescences in one line are staggered relatively to those in the adjoining lines, or by contiguous rounded studs having polygonal bases; and (2) the thickness of the film and the base-area of the elements are so chosen that the images formed by adjacent elements will not overlap for a given aperture, for example F/3.5, of the camera lens. For kinematograph picture-taking purposes a film is used having a thickness greater than the standard, and less than 26 lenticular elements per millimetre. For copying purposes, a film is used having more than 23 elements per millimetre and the silver emulsion is of finer grain than is usual. A film having a given number of elements per millimetre may be copied on to a film having a greater number of elements per millimetre. The Specification as open to inspection under Sect. 91 (3) (a) also states that in copying or projecting a film so produced, the pencil of light passing through each element is limited to the image associated with that element either by blocking out (as by reversal) the unexposed portions of the film before reproduction, or by employing a diaphragm of appropriate size in the light-projector during reproduction. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 24698/14, 207,836, 207,837, and 211,486.

Title: Method of and apparatus for carbonating liquids
Inventor: CLARKE LESLIE
IPC: B01F3/04
Filed: 1959-01-16
Abstract: 864,550. Aerating liquids. BRATBY & HINCHLIFFE Ltd. Jan. 18, 1960 [Jan. 16, 1959], No. 1657/59. Class 14 (1). In a method of carbonating liquids by injection to a finely divided state in a carbonator 25, Fig. 3, the liquid is first pumped to flow over the outer surfaces of refrigerant heat exchangers 11 within a cooling chamber 10 outside the carbonator 25 and to which carbon dioxide is supplied at a low pressure sufficient to exclude air so that the absorption of air by the liquid is minimized during cooling. The carbon dioxide may be bled from the carbonator 25 through a pipe 38, Fig. 2, and bleed valve 39 and is fed to the chamber 10 through a pipe 40. A bubble indicator 23 shows that the pressure in the chamber 10 is above atmospheric. The liquid is supplied at 17 to the base of the cooling chamber 10 on one side of a baffle 13 and is controlled by an electromagnetically operated valve 18 coupled to a level control 18a attached to the chamber 10. The liquid is re-circulated within the chamber 10 by a pump (not shown) and passes through a distributer 19 at the top of the chamber to flow over the heat exchangers 11 and descend, to the cool side of the baffle 13. The cooled liquid is removed by a pump B and fed to an atomizer 28 at the top of the carbonator 25. Carbon dioxide is fed to the carbonator through a reducing valve 36 and a heater 37 which heats the gas to atmospheric temperature. The carbonated liquid is finally withdrawn by a centrifugal pump D having a level control 50 which stops the pump when the level falls below a predetermined minimum. The pump D feeds liquid to bottle-filling apparatus &c. at adjustable pressures up to 50 lbs. per square inch above that prevailing in the carbonator in order to reduce the tendency to foam. Safety switches are incorporated in the chamber 10 to cut off the refrigerant when the temperature is too low and to stop the pumps when level in the chamber 10 is inadequate.
