Abstract: Equipment for the conveyance of coal in mining operations with reduced friction forces consists of a conveyor trough 1 with trough base 2 and side walls 3, a materials transporter 4 and driving equipment. The material to be conveyed and the materials transporter slide over the conveyor trough base. The materials transporter is constructed as a conveyor network having longitudinal strands 5 which transmit the tensional force, lateral connecting units 6 and conveyor network meshes 7 which permit lumps of the material being conveyed to penetrate the mesh and/or to be held where they penetrate. The conveyor network meshes intermesh with the driving sprocket roll, at least at the edges of the conveyor network. Friction between the transporter and trough base and/or side walls can be further reduced by the provision of a friction- reducing coating, which can be a layer of ice. <IMAGE>

Title: A heating means for a drier for drying washing
Inventor: VARNHOLT FRIEDHELM
IPC: D06F58/26
Filed: 1983-05-23
Abstract: The heating means comprises a heater housing (2) and a cover housing (3), the heater housing (2) accommodating the heating unit (1), and the cover housing (3) encasing the heater housing (2). This arrangement permits air flow channels (4) to be formed between the cover housing (3) and the heater housing (2), whereby a secondary air stream (14) may be produced which flows in a direction opposite the direction of the main air flow (13) during operation of the drier. This secondary air stream (14) causes the radiation losses of the heating means to be reduced, thereby permitting considerably improved efficiency to be achieved. The cover housing (3) and the heater housing (2) may each be comprised of symmetrically shaped half-shells of sheet metal. Stamped indentations (6 and 7) provided in the heater housing (2) and in the cover housing (3) form spacer supports between the two housing members and simultaneously serve as spot- welding locations for the housing members to be securely interconnected. <IMAGE>

Title: Portable slow-burning solid-fuel power plant
Inventor: FENGLER WERNER HERRMANN
IPC: B60L50/15
Filed: 1983-08-09
Abstract: Combustion of fragmented slow- burning solid fuel, such as wood fragments F, in the combustion chamber 735 of a portable combustion receptacle or pressure vessel 712 mounted on the rear of a vehicle, is initiated by igniting in the combustion chamber combustible starting fluid gas, such as propane gas from an external source 722 and ignited by a spark plug 756. Air is supplied by an air compressor 720 driven by a prime mover such as a turbine or electric motor. As soon as combustion of the solid fuel has become self-sustaining, the supplying of this starting gas is terminated. Meanwhile, the pressurized gas emitted from the burning solid fuel in the combustion receptacle is discharged into a power turbine 714 by way of a throttle valve 778. The output shaft of the turbine drives a speed-reducing transmission 716 which in turn drives the alternator 718. Two portable combustion receptacles are provided and used alternately, a single starting gas source and a single air compressor being provided for the two receptacles. <IMAGE>

Title: Beacon tracking system for a satellite reflector antenna
Inventor: WATSON BARRY KENNETH
IPC: G01S3/32
Filed: 1984-03-09
Abstract: In an automatic cartesian coordinate beacon tracking system for a communications satellite reflector antenna the higher order TM01 and TE21 circular waveguide modes are used as the tracking modes and are both extracted from the primary waveguide 3 by a first mode coupling section 4 comprising four equiangularly spaced transverse rectangular coupling apertures 10 opening separately into four rectangular waveguide arms 11 which lead to a hybrid network 12 arranged to isolate the two tracking modes from each other and then to vectorially subtract and sum the tracking modes to derive difference channel error signals  DELTA X and  DELTA Y related to the pointing error of the antenna. The dominant TE11 mode at the beacon frequency is extracted from the primary waveguide 3 by a second mode coupling section 5 axially spaced from the first mode coupling section 4 and comprising four equiangularly spaced longitudinal rectangular coupling apertures 13 opening separately into four rectangular waveguide arms 14 which lead to a second hybrid network 15 arranged to derive sum channel reference signals  SIGMA X and  SIGMA Y respectively from the extracted components of the TE11 mode at the beacon frequency. In some cases the second mode coupling section 5 of the tracking system may be arranged to extract up link communication signals from the RF feed chain in addition to the beacon tracking signal, the second hybrid network 15 being suitably designed to separate the extracted communication and tracking signals. <IMAGE>

Title: Process and apparatus for removing light oil from solids
Inventor: GREENFIELD CHARLES
IPC: C02F11/00
Filed: 1985-01-21
Abstract: In a process and apparatus for removing light oil from solids, residual light oil is removed from solids obtained in a process where aqueous solids (12) are mixed with a low viscosity, relatively volatile, water-immiscible light fluidizing oil (14) to obtain a mixture which will remain fluid and pumpable after removal of essentially its entire water content. The mixture of solids, water and fluidizing oil is subjected to a dehydration step by heat evaporation (22, 60, 76) whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered. The light fluidizing oil is then largely separated (86) from the solids. The solids carrying residual light fluidizing oil are then brought into direct contact (100) with a hot, inert gas (108), referred to herein as "blowing gas". The hot, inert blowing gas (108) effects the removal of the residual light oil from the solids. Light oil vapour removed from these solids is separated from effluent blowing gas by condensation (126) and recovered. Effluent blowing gas, free of light oil vapour, may be recycled. <IMAGE>
