Title: Automatic warehousing system - has loading and discharge lifts with truck rails regulated to align with racks
IPC: B65G1/06
Filed: 1974-04-26
Abstract: The system uses trucks receiving and delivering loads and a number of racks, with travel rails in them, divided both in the vertical and in the horizontal directions. Loading and discharge lifts travel along the inlet and outlet sides of the racks respectively, each having a cage traveling up and down and accommodating a truck, and automatic controls on the inlet and outlet sides transfer the loads between rack inlet and outlet with the aid of one of the trucks. These controls also regulate the lift (4) and cage, in which there are a pair of travel rails (7) which can be brought into line with those in the rack (1) to allow transfer of the truck (5). After the truck has transferred a load to or from a lift, the controls return it to the respective rack, whenever the other truck is to be loaded at the rack where the next loading or discharge operation is to take place, or retain it in the lift for transport to the system inlet or discharge point, whenever the other truck is not to be loaded at the other rack.

The treatment (1) can be carried out by (a) coating the particles with a metal (e.g. Cu, Cr, Ni or Ag), or a metal salt (e.g. a chloride of Ni, Fe or Al) or with a phenol, furan or epoxy resin; (b) forming an oxidized coat on the particles by immersing the particles in a solution of hydrogen peroxide, a chlorate, a hypochlorite, a perchlorate, nitric acid, ferric chloride, a dichromate, a mixed acid, a permanganate or a peracetate or by treating the particles with an oxidizing gas (e.g. oxygen, ozone, an oxide of sulphur or nitrogen or a halogen) which can be diluted with an inert gas (e.g. nitrogen, argon, hydrogen, steam or combustion gas) or (c) removing low boiling point or low melting point components by extracting the particles with a solvent such as acetone, methylethyl ketone, benzene, toluene, hexane, heptane, cyclohexane, methanol, chloroform or carbon tetrachloride. The softening point of the particles treated by extraction can be increased by heating between the softening and flow points of the pitch. The particles can be globular, filamentary or other shapes and can be composed of petroleum pitch, coal pitch (optionally containing 3 wt. per cent iron chloride) or pitch derived from by-product tars produced by thermal cracking of crude oil or naphtha. The heating can be carried out in a fluidized bed, fixed bed or rotary kiln. The crystalloidal pitch can be carbonized and graphitized, e.g. by heating in argon at up to 2400‹ C.

Title: Aerial observation from aircraft or spaceship - uses CCD sensor scanned synchronously with aircraft motion
Inventor: PETITFOURT JEAN CHARLES JOSEPH
IPC: H04N5/353
Filed: 1977-03-18
Abstract: A method of aerial reconnaissance is based on a charge coupled device consisting of a matrix of photo elements which scans a region (1) as it is overflown by an aircraft or space ship. An objective (4) projects an image of an observed scene on to the charge coupled device matrix (3) generating an electronic charge dependent on the illumination falling on each photoelement. Under the influence of a control logic circuit (5), successive rows of the matrix are scanned as the aircraft or space ship follows its course. The control logic circuit also synchronises a recorder or transmitter (6) with the matrix scan. A charge is accumulated in the matrix elements in accordance with the incident illumination and is removed serially in the usual way. The period between successive charge removals may be varies to accommodate variations in the level of incident illumination.
