Title: Heat recuperation system for open hearth fire - has cool air ducts each side of fire and discharging into room through hood
IPC: F24B1/188
Filed: 1974-12-03
Abstract: A method of recuperating part of the waste heat from an open fire which has a log fire on a hearth positioned forwards of the chimney, with a hood projecting from the chimney breast, uses an air entry underneath the hearth and passing upward wards through a duct each side. The combustion gases and smoke travels upwards through a chimney portion between the ducts. In this way, the cold air is heated by the heat from the combustion gases, the efficiency being increased by a set of baffle plates inside each duct. The heated air is then discharged forwards into the room through a bend at the top of each duct, passing through the hood.

Title: Light weight concrete compsn from low grade binder - comprising e.g. blast furnace slag silica and caustic alkali
Inventor: KALVENES OYSTEIN
IPC: C04B28/10
Filed: 1975-10-09
Abstract: The parent patent 816847 describes a process for reducing the amount of high quality hydaulic binder in the mfr. of light weight concrete forming a set with steam, in which a raw aq. mixt. enclosing 20-60% of a material rich in SiO2 and 10-70% of a low quality hydraulic binder, and in which 0.1-5 wt.% of an alkali metal hydroxide is added and the water content is adjusted to be >=35% before casting. The hydroxide activates the binder. If the amt. of hydroxide is large enough, high quality binders such as Portland cement need not be used. In this addition patent, it has been found possible to reduce or completely eliminate the silica rich material by increasing the amt. of low grade hydraulic binder above the limits set in the parent patent opt. up to 95%, provided the balance is alkali hydroxide and the hydroxide content is proportional to the low grade binder content. Cheaper products are obtainable showing excellent strength and low saline efflorescence.

Title: Corrugated sheet with corrugations closed at ends - is formed between punch and matrix on folding press in single or multiple operation
IPC: B21D13/02
Filed: 1976-02-02
Abstract: A corrugated sheet suitable for multiple applications, including container walls, is made in a pressing operation with the ends of the corrugations closed so that subsequent welding or shaping is not required. The process causes a shiping or flowing of the metal without tearing the fibres or distorting the ends of the corrugations. The sheet is shaped between a panel and a shaping metal mounted on a folding press. The sloping ends are formed with a set of smaller auxiliary corrugations which take up the excess of material produced by the operation. These may be formed in one operation, or may be produced by fixed portions of the punch, then undergo further forming by means of moving punch members.

Title: Measuring system for detecting polarity of direct current - senses voltages across windings for comparison with excitation voltage
IPC: H01F38/40
Filed: 1976-05-05
Abstract: The direction of flow of direct current in a conductor is detected by comparison with an excitation voltage and overcomes problems experienced when saturable transformers are used. Direct current (IDC) flowing in a conductor is detected by a circuit comprising a winding (10) and an excitation voltage supply (14). The winding produces a voltage output dependent on the direct current and a comparison circuit (18) compares the voltage with the excitation voltage. A second winding (12) connected in series opposition to the dirst winding is also connected to the comparison circuit in order to determine polarity. The voltage developed across a load resistor (16) is rectified (20) and enables the direction of the direct current flow to be determined.
