Title: Rotary feed valve for c-reducing mill scale
Inventor: CLIFFORD HOWARD ARTHUR
IPC: C21B5/00
Filed: 1970-08-20
Abstract: Carbon content controlled in metal smelters is carried out by supplying mill scale etc. out of a container via feed valve with rotor and blades to crush oversize and feed out along a gas pressure channel into the smelting vessel. The chute feeding into the lance used to inject the material into the steel is connected to a gas source and issues into the lance at its two ends respectively. The bladed rotor can be reversed to clear the entry or outlet to or from the rotary feed valve.

Title: Pressure-fermented spent beer malts - in mineral feeds and feed concentrates, with unlimited stability
IPC: A23K10/38
Filed: 1970-08-27
Abstract: Spent beer malt from breweries is fermented during 4 weeks under pressure, to reduce the water-content to =70%. The spent malt is then milled under addition of cattle salt and freed from indigestible parts. After mixing this with other feedstuff components, a stable feedstuff concentrate or mineral feed is obtained. The finished product has unlimited stability and gives practically dust-free feedstuffs.

Patent DE-2264877-A1 (DE)
Title: Neutron flux density distribution measured by long instrument - with one outer electrode, several inner electrodes and multicore cable
Inventor: RUNGE ERNST-GEORG DR
IPC: G21C17/108
Filed: 1972-03-10
Abstract: The instrument, operating esp. on the principle of measuring beta radiation induced current, comprises an elongated outer tubular electrode (collector) and a series of separate inner electrodes (emitters) arranged axially at intervals inside it. Separate conductors leading from each inner electrode form a multicore cable (esp. with ceramic insulation) leading to the reading instrument outside the reactor. This enables the current generated between each separate inner electrode and the common outer electrode as a result of the local in-core flux density to be read separately at the reading instrument. By combining all the leads to the separate emitters into a common multicore cable, disturbances which could render the readings from the short-length emitters unreliable are compensated; the effective sensitivity of the instrument is thus increased.
Patent DE-2339187-A1 (DE)
Title: Sewage water transport mechanism - has impeller with open-ended cells dipping into water and positioned parallel against wall
Inventor: BOTSCH BERTRAM DIPL ING
IPC: F04B19/10
Filed: 1973-08-02
Abstract: The mechanism is particularly for handling storm and sewage water, having an impeller with cells arranged in a ring pattern. The cells are open on one side on a plane at right angles to the impeller shaft, and the impeller dips below the level of the water which it lifts. As the cells travel upwards, their open ends are shut off by a fixed wall, and at the top they discharge into a reservoir whose forward edge extends to the edge of the impeller. The impeller can incorporate a round disc, carried in bearings on one side, and supporting two concentric hollow cylinders, between which radial partitions are mounted. The forward edges of these walls and of the cylinders lie on a plane at right angles to the impeller shaft.

The latter may be round or multi-hedral and may be double-sided with slits in both sides lying parallel to one another or offset. The sign may be formed as a stand up piece instead of as a mobile.
Patent DE-2401430-A1 (DE)
Title: Support bearings in vehicle differential casing - has roller bearings at each output shaft exit point and uses magnesium impregnated material
Inventor: ASHAUER KARL
IPC: B60K17/16
Filed: 1974-01-12
Abstract: The purpose of the design is to prevent damage and wear to the housing face due to the tendency of the half shaft to turn the case with it as it revolves. The design reduces the clearance necessary between half shaft and casing. The outer peripheral face of the support trunnion for the output shaft acts as the inner rail for a set of roller bearings. These are tapered roller bearings and the support face is similarly machined. The housing is made from magnesium impregnated malleable material and in the zone of the roller bearing it is hardened by induction.

Title: Seat for loader in armoured vehicle - ensures that loader is not exposed during travelling
Inventor: RAUCH HEINZ
IPC: F41H7/02
Filed: 1974-08-14
Abstract: The additional seat within the armoured vehicle is used to ensure that the gun loader body upper part does not project from the open turret whilst the armoured vehicle is travelling towards action. The loader is hence exposed to sniper and close combat hazards. The additional seat which is of temporary nature is hooked on supports within the vehicle. The seat consists of a loop made from a rope which has a chain link type metal hoops (1) for holding on the turret projections. In the mid-part of this rope loops is folded a canvas panel (2) which is able to slide on the rope but cannot be separated. The seat can be readily detached and stowed while not in use.

The first ultra-filtration is pref. conducted to give approx. 10% proteins. The process may be performed using a smaller surface area of membrane for the ultrafiltration than in prior processes. Increase of temp. is not required, and thus microbial attack is precluded.

Title: Longitudinally watertight communications cable - has core consisting of plastics insulated wires which is filled with water repellant composition
Inventor: SUTOR NORBERT DIPL ING
IPC: H01B13/32
Filed: 1974-12-19
Abstract: The core of the watertight communications cable is continuously or discontinuously filled with a water repellant substance such as petroleum jelly, which is applied in a state of medium viscosity during stranding of the wires at individual stranding points, or shortly before sheathing of the wires into an already stranded core. The filling compound is brought directly into the state of medium viscosity by shearing action with possible additional heating. The system is especially designed to prevent penetration of water along the length of the cable, thus minimising damage by localising the effect of leaks.

Title: Scrap/iron sponge melting shaft furnace - using oxygen/fuel counterflow in stages inversely proportional to oxidation capacity
Inventor: LANGHAMMER HANS-JUERGEN DR ING
IPC: C21C5/56
Filed: 1975-02-06
Abstract: A shaft furnace for the continuous melting of scrap or iron sponge in counterflow to an ascending oxygen/fuel flame is equipped with rings of burners by which the oxidation capacity of the flame gases is adjusted in inverse proportion to the vertical temp. profile of the shaft furnace. In the melting zone proper, only a partial (substoichiometric) amount of fuel and oxygen is introduced in the overlying stages fuel and air are added a stepped after combustion of the gases of combustion. High melting rate is thus combined with little oxidation of the metal charge in the melting zone.

The form panels are made in the shape of door-wing panels (4). The bridging plates are erected into previously erected concrete wall joints (2), to take up the vertical forces. When the formwork is moved the climber posts are led on the guide rails, the door-wing form panels being then swung away from the wall joint concerned. The whole entity is conceived as a machine which can be easily moved along as required.
