Title: Heating and cooling of rotary furnace - used for direct reduction of iron oxide-contg material with caking coal
IPC: C21B13/08
Filed: 1971-02-18
Abstract: Excessive agglomeration and sticking to the furnace walls is prevented by preliminarily heating the furnace to 300-800 degrees C (pref. 350-600 degrees C) with a gaseous or liquid fuel in the presence of a granular bed of a non-caking or slightly caking carbon-contg. material, and starting the feeding of a caking coal, followed by the iron oxide-contg material, only when the above temp. is exceeded.

Title: Synthetic lubricants for sealed refrigerant systems - with limited miscibility at vaporisation temp. of the refrigerant
Inventor: MALL KLAUS
IPC: C10M171/00
Filed: 1973-09-10
Abstract: Synthetic oils with limited miscibility with the refrigerant at its vaporisation temp. are used as lubricants in sealed refrigerator systems. The condensed refrigerant, e.g. ammonia, separates into a phase rich in entrained oil carried over from the compressor, which has good solubility for refrigerant and good flow properties, with viscosity at 240 degrees K similar to that of petrol, and a phase consisting of almost pure refrigerant. The oil-rich phase flows under gravity and separates as a layer at the bottom of the apparatus, from which it is returned to the compressor oil without use of addnl. equipment of energy. Conventional mineral oils dissolve little ammonia and have poor flow properties at low temps. Polyglycols with suitable viscosity for use as lubricants and good flow properties when mixed with a refrigerant in the range of 200-230 degrees K.

Title: Folded thermoplastics canopy lining - with fixing wires in loops inserted by cutter-feeder between folding/welding clamps
Inventor: HABENICHT ROLF
IPC: B60R13/02
Filed: 1973-10-17

Title: Breakage detector for windows doors etc. - initiates alarm when unauthorised entry using light source and photo-detector
Inventor: HAAG GUENTER
IPC: G08B13/184

The modulated light source may be a laser.
Patent DE-2354421-A1 (DE)
Title: Lorry loading floor support structure - has inclined longitudinal supports which can be detached from the chassis
Inventor: WACKENHUT ERNST
IPC: B62D33/02
Filed: 1973-10-31
Abstract: Such supports are often fixed to the chassis by clamps and screws on the longitudinals. Such support is insufficient for many loads - the cross supports themselves being poorly fixed, whether of steel or wood. The patent covers a more simple form of support, which is also stronger. The longitudinals are sloped outwards and upwards from the chassis. They are pressed to a special section and can be firmly fitted or welded to the cross members. The longitudinals can be screwed or otherwise fixed to the floor and by a number of methods to the chassis.
Patent DE-2355954-A1 (DE)
Title: Oversteer compensator for automobile trailing arm suspensions - uses non linear spring elements within wheel carrier of non steerable axle
Inventor: SORGATZ ULRICH DIPL ING DR
IPC: B60G7/02
Filed: 1973-11-09
Abstract: A side force on a wheel attached to a vehicle by trailing arm suspension, can, if great enough, cause the suspension arm and bearing to deflect sufficiently to cause the plane of rotation of the wheel to move through an angle giving rise to oversteer. This is compensated by allowing the wheel carrier to rotate in the opposite direction about an axle against the force of a spring. This spring is best chosen to have a load deflection curve giving a greater deflection per unit load, at higher loads, i.e. a conical spring washer. The springs are pre-loaded in position against a stop to maintain stability during normal driving.
