Title: Cooling very hot gas, esp. gas leaving steel converters - by injecting water mist into gas extn. duct
IPC: C21C5/38
Filed: 1975-10-08
Abstract: Very hot gas is cooled by the evapn. of a liq. The novelty is that >=1 sheet of liq. mist is produced by the collision of jets of liq., the mist being made very close to the point where the gas is collected; and the gas is compelled to pass through the mist. The mist is pref. made in the rising part of a gas extn. duct located directly above the gas outlet of a furnace or reactor. The pref. plant consists of a gas exten. hood followed by a metal duct contg. two spraying nozzles and an outlet for the excess liq. which is not evaporated and travels into a gutter. The hood is pref. mobile w.r.t. the duct. The plant can be used in the steel or cement industries where a gas must be cooled before purificn. and/or use as a reactant, fuel, or discharge to the environment, e.g. above a steel making converter. This light, simple device is extremely efficient and demands little maintenance, as the surplus liq. is used to cool the metal duct.

Title: Windmill with double rotor - has central wind screen in housing to direct air flow onto active blades only
IPC: F03D3/02
Filed: 1975-12-15
Abstract: The double-rotor windmill has the rotors on vertical and parallel axes for conversion of wind power into mechanical or electrical energy. The wind is directed by the housing solely onto the active rotor blades and the cross-sectional area of the inlet for the wind is many times that over which it acts on the rotors. The inlet cross-section automatically remains at right angles to the wind direction. There may be a central screen preventing the wind from acting on the blades inside the housing, and directing it towards the active ones. The axis of the power generator drive shaft can coincide with that on which the housing slews, and it can be coupled direct to one of the rotor shafts to which the other one is geared.

The modules have an axial recess which houses a float (10) and have a vaned (13) exteriors. The vanes (13) project radially from a hub (6) giving a paddle wheel appearance and reduce the transfer of water turbulence from one lane to another during races. The hub may be of a hollow truncated cone form with an integral sleeve (8) and radial flange (12). The flange extends externally from the open end of the cone, and the sleeve (8) cantilevers axially inside the cone from a closed base (7). The vanes radiate from the hub and the outer edges cantilever away from the hub to form axially parallel tongues.

Title: Gravity operated power generator - has masses mounted on pivoted arms and guided eccentrically around wheel by cam to give continuous turning moment
IPC: F03G7/10
Filed: 1977-01-24
Abstract: The vertical wheel supports rods which can slide radially. The inner ends of the rods run on a cam which is eccentric to the wheel. The outer end of each rod is hinged to a lever whose other end carries a mass. The masses are guided on a second cam so that on one side of the wheel they are further out in the radial direction than on the other side. As a result the moments exerted by the masses on the wheel do not balance and there is a net turning force on the wheel. The rotation of the wheel causes the masses to move along the cam and the process is continuously repeated.

Title: Stabilizer for rotary well drill string - including tubular sub with readily removable shrink fitted wear resisting sleeve
IPC: E21B17/10
Filed: 1977-03-09
Abstract: A well drill string stabilizer is claimed including an externally-tapered tubular body for incorporation in the drill string and a wear-resisting sleeve with a complemental tapered bore shrink-fitted onto the body. There is provision for pressurizing the region between the tapered surfaces of the body and the sleeve to facilitate installation of the sleeve on and its removal from the body. Seal rings are provided to confine the pressurizing fluid between the body and the sleeve. At its end surrounding the smaller dia. portion of the body the sleeve has a radially-inwardly extending projection presenting a terminal planar bearing surface or relatively large area normal to the sleeve axis. A drill collar or bit secured to the smaller dia. portion of the body abuts the bearing surface and urges the sleeve against a shoulder presented by the larger dia. portion of the body. No undue radial deformation of the sleeve or the body can occur such as might inhibit removal of a sleeve and/or fitting of a replacement sleeve.

Title: Optical scanning of magnetic disc marker holes - using LED scanner with wavelength characteristic of magnetic particle size to avoid errors
Inventor: KELLER RONALD J
IPC: G11B27/26
Filed: 1977-05-25
Abstract: The identification of marker holes in magnetic disc recordings of digital data is improved by matching the optical light source wavelength to that of the magnetic particles. The disc (12) has a backing layer (13) of polyester film, approximately 75 microns thick. The surface (14) is coated with magnetic particles in a bonding material and is 25 microns thick. A GaAs infra red LED (16) is focussed onto the disc to locate marker holes (15) and a photo detector (17) generates an output when aligned. The LED emission is in the visible spectrum with a wavelength of 0.5-0.7 micron, which is characteristic of the magnetic particle size.
