Title: Liq. flow heat dividing system - adds non-condensing gas, such as air, to liq. flow to be vaporised
Inventor: TEBBENHOFF EBERHARD DR
IPC: B01D3/10
Filed: 1979-09-15
Abstract: The system divides the heat content of a liq. flow of a given initial temperature into a first partial flow of a lower temperature and a second flow of a higher temperature than the initial value. The flow is partly vapourised by an ejector, using a colder liquid propellant jet. The vapourised portion in the propellant jet is compressed up to condensation, yielding the condensation heat to the second partial flow. The remainder of the flow is divided into the propellant jet and the first partial flow. The liquid flow to be vapourised is mixed with non-condensing gas, typically air. The evaporation chamber (2) has a porous wall (13) for ingress of finely divided air.

Title: Collector for solar energy with two circuits - transferring radiated heat direct and acting as heat pump
Inventor: SIGMUND THEO
IPC: F24S10/75
Filed: 1979-10-02
Abstract: A current of air is generated by a transverse flow blower through an air inlet opening and an air outlet opening positioned in opposition to each other at the ends in the lengthways direction of the exchanger plates in a collercot for solar energy. Two pipe loops, completely separate from each other, form two separate flow circuits in direct heat contact with the exchanger plates. These are aligned obliquely to the cover of the collector which is domed upwards, and below the plates an electrical heater is installed which is supplied by a wind-driven generator. The one circuit can be used directly for transmitting the energy of the sun whilst the other acts as the vapouriser of a heat pump. The collector is able to take up energy from the environment when there is reduced or complete absence of sunshine, and deliver it to the user.

Title: Adjustment arrangement for thermo-bimetal on carrier - uses elastic deformation of thermo-bimetal via rotating connecting vane
Inventor: SCHMITT HERMANN
IPC: H01H37/20
Filed: 1979-11-27
Abstract: The arrangement for adjusting a thermobimetal clamped on the end of a bimetal carrier avoids the high cost of assembly of conventional arrangements and results in a simplified adjustment operation. A connecting vane (22) attached to the thermobimetal carrier (14) lies parallel to and overlaps the thermobimetal (24). An edge of the connecting vane lying transverse to the thermobimetal is brought into contact withthe with the thermobimetal by rotating the connecting vane about an axis in the plane of the vane and perpendicular to the thermobimetal. Further rotation causes elastic deformation of the thermobimetal. The connection between the vane and the carrier is via a bridging piece of smaller cross-section than the connecting vane. The edge of the vane causes a convex deformation of the thermobimetal.

Title: Model motor vehicle drive and roadway system - comprises dual platform construction modules with magnetically-linked drive vehicle underneath road and remote signalling channel
Inventor: FOERSTER MALTE E C DR
IPC: A63H18/14
Filed: 1980-01-24
Abstract: The upper surface of a plate made of non-conductive material constitutes the surface on which vehicle models move whereas its lower surface is provided with a conductive layer from which power is supplied to an electric vehicle over contact brushes. A metal plated base plate constitutes the other power pole. The two plate segments are connected via rigid distance pieces and insulator discs. Prefabricated modules of this type may be assembled into various street shapes. The electric vehicle is invisibly coupled to the upper vehicle model by permanent magnets with linkage to the iron wheels of the model. A set of wheels runs on the interior face of the upper plate to maintain an even spacing of the magnets from the vehicle above. A further hollow space is provided below the base plate by a bottom plate and spacers, for accommodating manually settable proximity control devices, either to steer the electric vehicle, or to be influenced by it. There are also proximity detectors on all the electric vehicles which cause them to reduce speed on approach of another vehicle whereby collisions are avoided. Remote signalling channels may also be carried by the Traffic simulating vehicle models responding to instructions to switch on any of their signalling lights.

Title: Hermetically seamed composite container - has metal ends and fibre composition body joined by double seams
Inventor: GRIFFITH EDWIN DALE
IPC: B65D8/04
Filed: 1980-01-25
Abstract: The hermetically sealed composite container is formed by double-seaming a pair of compounded metal ends (16) to extended flanges (22) having a length of at least 0.075 in. on the opposite ends of a can body. The compound (34) is bonded to an inner liner (20) on the can body to provide an effective seal. The compound material is placed in the seaming panel (30) and curl area (32) of the metal ends so as to provide a more extensive seal area when the metal ends are double-seamed with the extended flanges on the can body. The extended length flanges provide a considerably greater contact area between the can body inner liner and the metal ends when the metal ends are double-seamed to the can body.

Title: Granular material fed into fluidised bed esp. pulverised coal furnace - in zones of limited upward gas flow to prevent premature discharge
Inventor: SCHILLING HANS-DIETER DR RER N
IPC: F27B15/00
Filed: 1980-06-14
Abstract: A method of feeding granular material into fluidised bed reactors consists of introducing the material above a region of the perforated bottom plate where the upward ascent of the fluidising gases is reduced or entirely prevented. Pref. the perforated plate has zones where the gas permeability is reduced or entirely absent, th the bed material being introduced in these zones. Pref. conical, pyramid-shaped or prismatic components may be mounted above the perforated plate to inhibit the upward flow of the gas in these local zones. Process is partic. useful for where fine granular material introduced into a fluidised bed is subjected to the risk of being blown out of the bed before the required reaction, such as combustion, has been fully completed. A typical application is in the fluidised bed combustion of pulverised coal.

Patent DE-3105200-A1 (DE)
Inventor: BISSCHOP HUBERTUS A J M
IPC: C21C1/10
Filed: 1981-02-13
Abstract: A method of and a ladle for the treatment of a cast iron melt with a substance capable of inducing the formation of spheroidal graphite utilizes an elongated generally cylindrical vessel lined with a refractory and formed at opposite ends with cylinder bottoms. The vessel can be tilted between a horizontal and upright orientation and angularly displaced about a longitudinal axis at least in its horizontal orientation. A partition in the vessel adjacent one of the cylinder bottoms defines a chamber at one end of the vessel opening within the vessel toward the opposite end thereof and disposed at an upper portion of the vessel in its horizontal orientation. A closable opening at the other end of the vessel enables a cast iron charge to be introduced into the vessel in the horizontal orientation thereof. The vessel is then tilted upwardly to effect the reaction and swung back to its horizontal orientation for deslagging before the charge is tapped by angular displacement about the longitudinal axis.
