Title: Aircraft contrail dispersion
Inventor: BRIGHT CHRISTOPHER GRAHAM
IPC: A01G15/00
Filed: 2009-11-13
Abstract: A method of reducing the amount of water in a region of air 12, the contrail of an aircraft for example, comprising forming seed ice crystals 16, dispensing the seed ice crystals towards the region of air, allowing water in the region of air to freeze or deposit onto the seed ice crystals, and allowing the resulting ice crystals 20 to move from the region of air so as to reduce the amount of water in the region of air. The seed ice crystals may be formed by producing ions such that the seed ice crystals seed on the ions, where ions are produced by irradiating the air using microwaves, ultra-violet radiation, X-rays, gamma rays, corpuscular radiation, lasers or by applying an electrical potential to the air. The seed ice crystals may also be formed by providing compressed air comprising water vapour, cooling the compressed air and expanding the compressed air so that it's further cooled to below the dew point of the air or by spraying water into the air. An assembly is also claimed.

Abstract: 590,449. Delivering measured quantities of liquid. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. April 20, 1945, No. 10032. Convention date, April 16, 1943. [Class 106 (v)] In apparatus for delivering measured quantities of liquid, comprising one or more gaugers, means are provided for draining off the inner surface of the gauger, the calibration of the gauger taking into account such systematic eliminations of drainage. Liquid is pumped along a conduit 2, through a reversing system 3, up a pipe 4' into a gauger 1', the filling-up of which moves a float 8<1> which actuates the reversing system 3 and the gauger 1<1> then discharges into a chamber 6 while another gauger 1 is filling. Channels 10, 10<1> connected by conduits 11, 11<1> to a vat 12 drain off liquid as the level in the gauger drops from the float 8' to the level B-B and then drain off the liquid remaining on the walls. This more or less constant amount of drainage is taken into account when calibrating the gauger. A device 9 in the chamber 6 prevents discharge into this chamber until it is sufficiently empty.

Abstract: 947,883. Photo-electric direction finding. GIANNINI CONTROLS CORPORATION. March 20, 1961, No. 10081/61. Heading H4D. [Also in Divisions G1 and H1] A device which can indicate the elevation or azimuth of a source of light comprises a partspherical carrier 100 having three layers superposed thereon, a layer of resistance material 112, a photoconductive layer 114 and a conductive layer 116. Light is focused on to the photoconductive layer by lens 104 to cause conduction between the resistive layer and the conductive layer. With the layer broken at 120 by an insulating section, at either side of which electrical connections 122 and 124 are made to a source of potential difference, the potential appearing at the conductive layer due to the conduction of the photo-conductive layer will correspond to the azimuth of the light source, alternatively if connections are made to the circumferential edges of the resistive layer the voltage picked off will depend on the elevation of the source. Other forms of potentiometers or variable resistors are described (see Division H1). Reference has been directed by the Comptroller to Specification 914,860.
