Title: Hydrogen generation by reacting scrap iron with steam in shaft furnace - and recycling magnetite obtd. to iron and steel mfr., reducing energy consumption
Inventor: CZARNOWSKI GOTTFRIED VON DIPL
IPC: C01B3/50
Filed: 1992-08-11
Abstract: H2 generation by a modified Fe-steam process is carried out by reacting scrap Fe with steam to H2 and Fe304 in a shaft furnace of the usual type and recycling the Fe304 to iron and steel mfr.. Pref. the Fe304 is oxidised with 02 to Fe203 in another process stage and the heat released is used to generate steam for the Fe-steam process. C0 gas, in the form of converted waste gas from the steel works, is used as reducing agent. The H2 is removed from the reactor selectively through a mol. sieve, so that the H2 yield is increased by shifting the chemical equilibrium. USE/ADVANTAGE - The energy consumption is reduced considerably and the H2 yield can be improved by using a mol. sieve for selective removal of H2 from the reactor.

Inventor: BERNDT ERNST
IPC: C07K1/12
Filed: 1992-09-24
Abstract: Prodn. of protein-hydrolysates from animal and/or vegetable substrates comprising: (a) comminution of the substrate; (b) heating the comminuted substrate; (c) mashing the substrate to a pumpable mass; (d) decomposing the substrate with an electrical discharge; and (e) sepn. of the aq. phase of the decomposed prod. from solid and water-immiscible residues. The entire process is carried out at a temp. below the protein coagulation temp., and step (c) is carried out using an aq. hydrolysate phase from the decomposed prod.

Title: Circuit with two mutually synchronising VCO's - has two identical phase locked loops, each with oscillator phase discriminator, and loop filter.
Inventor: BOSHOLD KLAUS
IPC: H03B5/26
Filed: 1992-09-24
Abstract: The circuit has two identical phase locked loops (K,K'), each giving a definite amplification for DC voltage. The phase control loops are coupled via connecting lines between the junction points of two oscillators (VCO1,VCO2) and two phase discriminators (PD1,PD2) of the two phase locked loops, with a summation phase twist of 180 deg.. Thus, the two oscillators have a common frequency and constant phase difference after an oscillation start time period with at least partly overlapping full region. The circuit has pref. a working point control such that the oscillator control voltages are averaged and then the working point of an operational amplifier, allocated to the loop filter (TP1,TP2) is controlled. USE/ADVANTAGE - For directional radio couplers. Simple design for mutual synchronisation.

Inventor: HUEBLER GERHARD DR
IPC: G11B5/848
Filed: 1992-10-14
Abstract: The prodn. of a magnetic recording material (I) involves using an extruder-caster with at least 2 slots for wet-wet casting of several superimposed layers on a flexible, non-magnetic substrate; the upper lip of the common slot aperture is set back from the lower lip, and a rectangular magnet is arranged behind and parallel to the substrate, with its upper edge facing the extruder opening at a distance of 0.1-5 mm, as described in DE4226139. The upper magnetisable layer (OS) has a dry film thickness greater than 2.0 microns, and the adjacent lower (pref. non-magnetic) layer (US) has dry film thickness less than 0.5 microns. USE/ADVANTAGE - The process enables the prodn. of (I) (magnetic tape etc.) by simultaneous wet-wet coextrusion of a relatively thick magnetic layer with a thin non-magnetic layer, without casting faults, to give a prod. with good surface smoothness, adhesion and wear resistance.

Title: Floor hinge for automatic closing of swing door - has lubricating and working oil arranged respectively in separate mechanical and hydraulic structural parts
Inventor: LEE MOON HYOUN
IPC: E05F3/12
Filed: 1993-06-07
Abstract: The floor hinge has a hinge pin (2), which is coupled to the swivel column. A cam mechanism (21,24) is coupled with a piston (32) across a piston rod (23) and is spring loaded to one side by a pressure spring. A non return valve and several lines are provided for the restoring movements of the piston by the pressure spring. The hinge pin (2) and the cam mechanism (21,24) are accommodated in a hinge box (1). The piston (32) and the non-return valve (33) are mounted in a cylinder (31), also the lines. The hinge box and the cylinder (31) are separated by a partition (12) and a sealing ring (22) so that respectively a cam chamber (20) and an oil chamber (30) are formed. A cap (40) is fixed at the end of the cylinder (31) to seal the oil chamber (30). A limit switch (39) is provided on the inner side of the cap. The switch can be e.g. an eddy-current or impedance sensor which monitors the movement of the piston (32) and transmits the closing state of the door to a recognition circuit. The latter can be remotely controlled to restrict the entry to only certain people by activating an alarm e.g. lamp or buzzer circuit. ADVANTAGES - Non problematic working floor hinge gives longer working life. Wear at frictional surfaces is reduced and contamination of working oil is prevented. Door can be automatically closed quickly and jerk free.

Title: Adhesive tape, self-adhesive on one side, in prepared lengths on rolls, with non-adhering gripping pieces
Inventor: STROBEL FRIEDRICH
IPC: C09J7/20
Filed: 1993-06-29
Abstract: Adhesive tapes in prepared lengths with non-adhesive gripping pieces can be used for many applications in daily life. Here it is often advantageous, on the one hand, to have the supply roll ready to hand and, on the other hand, to be able to use both hands for the planned work. The roll according to the invention, having an egg-shaped cross-section and a finger hole in the pointed, narrower half, can be placed on one finger like a finger ring, so that on the one hand the adhesive tapes are ready to hand at any time and, on the other hand, the occupied hand can still be used fully for many operations. As a result of the special arrangement of the prepared lengths on the roll having an egg-shaped cross-section, it is ensured that only one gripping piece is always ready to hand and only one piece can always be drawn off.
