Title: Discontinuous metal oxide reduction - esp. to produce sponge iron using one cooling reactor and two reduction reactors (BR 9.12.80)
Inventor: CELADA JUAN
IPC: C21B13/04
Filed: 1980-04-09
Abstract: Discontinuous reduction of metal oxides to the metal is described in which separate fixed beds of metalliferous material treated simultaneously in at least one cooling reactor and at least two reduction reactors, and in which a reducing gas composed of CO and H2 is used for reducing the material, and which also may contain methane CO2 and steam for cooling the material. Specifically, the gaseous effluent from the cooling reactor is circulated in parallel in the metalliferous mass in the reduction reactors. The gas introduced into each redn. reactor is heated before entering the reactors, and the gas effluent from them is cooled to remove water. Part of this cooled gas is then reheated and recycled to the reduction reactors. The amt. of reducing gas required per ton of metal, is reduced.

Title: Light weight head-supported illumination device - has remote arc light source with heat filter connected via optic-fibre cables to spectacle-frame light output bundles
IPC: F21V8/00
Filed: 1980-05-23
Abstract: The appts. comprises an eyeglass-type frame, a bundle of lightweight, polymer optical fibers terminating at the frame in spatially sepd. smaller bundles, and a remote light source capable of supplying the optical fibres with high-intensity visible light without damage to the fibres. The polymer optical fibres are terminated at the frame to provide focused light illuminating an area located a preselected distance in front of the frame. Use of lightweight, polymer optical fibres allows the fibre bundle to be divided into two or more smaller bundles for termination on each side of the frame, or in an alternative spaced arrangement along the top of the frame, producing a wide field of balanced light, without the harsh shadows inherent in the use of a single point source of light.

Title: Electronic safety ski binding - has reference generator and amplifier in parallel to compare output of force measuring device on ski or legs of skier
Inventor: EIBL VOLKER
IPC: A63C9/088
Filed: 1980-09-22
Abstract: The circuit uses a comparator amplifier circuit to compare the balance between forces with that of a reference generator so that force related increasing and decreasing voltages can be translated into a binding release action. The reference generator output is adjustable so that the release point can be suited to the skier, i.e. body weight, conditions etc. The force measuring device (10) is attached to the ski or skiers legs and provides an output signal which is fed to both an amplifier (11) and an RC bias circuit in the reference generator (12). The output of the amplifier (11) and the modified generator output (12) are compared at the input of a comparator (13). The comparator output to the binding release mechanism is determined by an operate point on the Force/time curve for the generator output (12).

Title: High current switch with plunger operating arm - has contacts swung by bridging piece with arm guided by channels in plunger
Inventor: SCHERZER WOLFGANG
IPC: H01H23/16
Filed: 1980-12-19
Abstract: The switch for relatively high currents, has a block containing two spring loaded pins with rounded ends which are forced downwards against contact elements to swing them from an intermediate position into a contact bridging position. This block is mounted on a bridging piece with an arm extending upwards from it with a peg extending sideways to travel in control channels in a vertical block above. This block forms the bottom of a switching arm. The channels are divided by a partition and terminate in upper and lower return paths adjacent to the ends of the partition. The lengths of these channels determine the duration of contact action between the middle contacts and the side contacts, controlled by the speed of travel of the switching arm.

Title: Gas generator for heaters or vehicles - producing gas free from tar or pyroligneous material from wood
IPC: C10J3/44
Filed: 1981-04-30
Abstract: A generator for the gasification of wood fuel produces a gas free of tars and heavy products which is suitable for automotive use or for fixed heating systems. Wood, or other biomass fuel, is fed into a vertical, cylindrical hopper from which it falls by gravity into a stainless steel combustion zone equipped with a series of tuyeres having adjustable dampers each air inlet to regulate the air feed. The number and size of tuyeres is determined by the gas flow rate required. A sufficiently high temperature is employed to cause cracking of tars and other heavy combustion products. The exit gases are passed through a cyclone to remove cinders before use.

Title: Electronic controller for agricultural sprinkler valve - has position sensor on wheel in valve operating mechanism to interrupt motor power to conserve energy
IPC: A01G25/16
Filed: 1982-01-07
Abstract: A valve connected to a sprinkler liq. supply circuit is controlled by an electronic circuit utilising an irreversible electromechanical system to control opening and closing of the valve. Selectors on guide rails permit operation of the controller and also define the duration of the sprinkling sequences. The valve comprises a ball which is lifted from its seat against the liq. flow by a push rod. The push rod is moved by a cam rotated by a shaft driven by an endless screw and wheel from a step motor. The motor is powered from the electronic circuits and a detector senses the valve position from that of the wheel. The detector is thus able to interrupt the power supply to the motor to conserve energy.
