Title: Improvements in or relating to radio rotary beacon arrangements
IPC: G01S1/02
Filed: 1954-03-12
Abstract: 777,055. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. March 12, 1954 [March 19, 1953], No. 7243/54. Drawings to Specification. Class 40(7) Relates to phase beacons in which a cardioid radiation pattern is rotated at 30 c/s and a 30 c/s reference signal is transmitted from an omni-directional aerial by frequency modulation on a 10 kc/s. subcarrier which is amplitude modulated on to a carrier of the same frequency as the directional transmission. In such a beacon interaction between the two transmissions: may cause the omni-directional and/or the directional transmission to be amplitude modulated at 30 c/s. or some harmonic thereof which results in bearing errors and according to the present invention the unwanted modulation is neutralized by (1)' amplitude modulating the omni-directional carrier with an auxiliary 30 c/s. signal synchronized with the cardioid rotation and of selectable amplitude and phase and/or (2) amplitude modulating the directional carrier by a similar 60 c/s. auxiliary signal, Fig. 1 (not shown). Alternatively the unwanted amplitude modulation in the transmission line to the omni-directional aerial may be detected by a rectifier and applied through a low-pass frequencyselective negative feedback path to the input of the non-directional amplitude modulator, Fig. 2 (not shown). The directional radiation pattern may be produced by a horizontal dipole rotating in a cage of vertical conductors.

Title: Improvements in electrostatic spraying apparatus
Inventor: FRASER O B E REGINALD PERCY
IPC: B05B5/03
Filed: 1963-02-22
Abstract: 1, 026, 413. Spray-producers. DE MACHINES ELECTROSTATIQUES. S.A. Feb. 11,1964 [Feb. 22, 1963], No. 7244/63. Heading B2F. An electrostatic spraying apparatus, suitable for spraying a liquid such as paint, is adapted to produce either a low velocity wide angle spray, the dispersion of the spray being aided by a swirling stream of air, or a high velocity narrow angle spray, and includes means for changing from one type of spray to the other whilst the apparatus is in operation. In the embodiment of Fig. 1 paint is fed through a passage 7, along passages between fins 12 while in contact with a material 11 of high resistivity on the internal surface of a hollow electrode 6, and through the gap surrounding the head of a pintle 8 which is spaced from a conical seating recess 10. Compressed air is fed through a passage 13 to an annular chamber 14, through swirl slots 19a and out through an annular opening 26 so that it distributes the paint at a spray angle of between 70 and 140 degrees and at a velocity of about 1Oft/sec When an outer portion 1 of the apparatus is moved with respect to an inner portion 5, Fig. 2 (not shown) valve surfaces 17 and 18 are separated and the compressed air by-passes the slots 19a and issues from the opening 26 as a high velocity non-swirling stream, the spray angle being between 17 and 40 degrees and the spray velocity being 40 ft/sec. Fig. 4 (not shown) depicts an arrangement in which the pintle is controlled by an operating rod and tangential passages leading into an annular cavity produce a swirling stream of air from the opening 26. A high D.C.potential is applied to a member surrounding and spaced from the pintle and paint is fed into the apparatus through a flexible tube. Initial movement of the rod displaces the conical head of the pintle and allows the flow of paint which is distributed by the air stream. Further movement of the rod moves the said member to the right thereby decreasing the opening 26 and producing an air stream of higher velocity. The apparatus of Fig. 5 (not shown) includes a valve operable from the gun butt to control the flow of air through a first passage from which it is fed via tangential passages to the nozzle 26 and emerges as a swirling spray, and through a second passage which produces a high velocity stream of air from the nozzle 26. Fig. 6 (not shown) is provided with an air supply similar to that of Fig. 5 but the liquid supply is provided centrally of the apparatus and the pintle is eliminated.

Filed: 1917-06-05
Abstract: 115,712. Radford, A. P. June 5, 1917. Moving-chamber apparatus; varying quantity measured in; operated by the receptacle. -In apparatus typically for supplying measured quantities of syrup to aerated-water bottles, the measuring- chambers are upon the periphery of a rotary, inclined, annular, supply reservoir, charging in the lowest position, and discharging at the highest into the bottles or other receptacles, which pass around with the reservoir and control the discharging operation. By means of gearing 5, 6 and a suitable clutch, the annular trough 2 is rotated about an inclined stationary axle 3, the liquid being maintained at a constant level in the trough by means of a ballcock 7 upon the supply pipe. The open measuring-chambers 8 fill through apertures 9 towards their lower ends and may be regulated in capacity by means of adjustable displacers 18, discharge occurring through pipes 10 at the upper position. As charging takes place, air is forcibly expelled through the discharge pipe, whereby drops of liquid remaining in the pipe are blown into the bottle. The receiving-bottles 12, upon adjustable supports 11 maintain a spring arm 15, 13 in the path of a stop 16, whereby more than one rotation of a bottle becomes impossible, the clutch slipping as the parts abut. A second stop (not shown) prevents continued rotation if a removed full bottle is not replaced by an empty one. Fig. 2 shows an alternative measuring-chamber in which an air-vent pipe 20 is adjustable in height and is sealed when the syrup rises above its lower end. In another construction, the measuring-chambers are formed by means of radial partitions within the supply reservoir.
