Patent FR-2290817-A1 (FR)
Title: Convective heating element has U-shaped heating tube - with sheeting profiled into aerofoil section to increase heat transfer to air
IPC: F24H3/00
Filed: 1975-10-17
Abstract: The convective heating element consists of a U-shaped heating tube (1) and stream-lined sheeting (2.1) bent around the tube so that any section through it at right angles to the axis of the tube resembles an aerofoil section. The aerofoil section is hollow and its conventional leading edge faces the incoming airflow. The aerofoil section maybe approximated to by a triangle. The section is constructed in halves that bolt together. The aerofoil sheeting is in good thermal contact with the heating tube and it ensures optimum heat transfer to the circulating air even at the bend in the U.

Title: Dry type cooler tower - having lower square and upper circular cross section with connecting piece between
Inventor: HEEREN HERMANN
IPC: F28B1/06
Filed: 1975-11-14
Abstract: Natural draught cooling tower of the "dry" type consists of two sections one above the other. The lower is of rectangular, pref. square cross section, in the upper part of which are fitted heat exchange elements so as to completely fill the cross section. The upper section is circular or polygonal in cross section and has no heat exchange elements. There is a connecting piece between the two sections. The tower is of use for cooling condensate in power stations or other cooling duty. The change in section described combines the advantages of both cross sections by avoiding dead space but giving a good draught.

Title: Multilayer epitaxial monolithic rectifier bridge - includes Darlington pair formed on same silicon substrate
Inventor: BONIS MAURICE
IPC: H01L27/08
Filed: 1975-12-17
Abstract: The PN rectifier bridge is formed on a single substrate in a multilayer epitaxial form. The design overcomes problems such as, thermal dissipation, reliability, reject rate during production and to allow overall reduction in manufacturing costs. Included on the same silicon monocrystalline substrate is an emitter to base coupled Darlington pair fed from the junction of two like electrodes of the bridge diodes. The substrate carries a series of epitaxial layers of alternate types of conductivity. The diodes of one bridge arm are formed by the junction between the substrate and the adjacent overlying layer. The second pair are similarly formed by the junction between the coplanar outer layer and its underlying local zone.

Title: Lock for sliding cable - uses links pivoting on backing plate to give elliptical jaw path
IPC: F16G11/10
Filed: 1976-01-21
Abstract: This automatic cable lock consists of two jaws (1, 2) forming a fairlead and forced by pivoted links (6) to move together when displaced laterally. It is cheap to produce most parts being simple stampings. The lower jaw (2) is forced to move in a straight line as the pins (4) forming pivots for the links move in a slot in a backing plate (5). There are two swinging links (6), each pivoted (3, 4) to each jaw, near one end. At the other end, the links are connected via short transverse links (7) to the main pivot (8) in the backing plate. The linkage ensures that the path of the movement of the upper jaw is almost elliptical and gives an almost constant locking force.

Title: Thermoplastic sack with air vent - for packing powdered or granular products
IPC: B65D33/01
Filed: 1976-01-30
Abstract: In a sack or bg for packing powdered or granular materials, are fabricated from a thermoplastic layer or film, of polygonal form when empty and having an opening on one side of the polygon and a heat-sealing seam joining the inner surfaces of the front and back wall running along a further side of the polygon, at least one air vent channel or passage is provided in the form of a local interruption of the heat-sealed seam, facilitating connection of the sack interior with the atmosphere or outside air, when the sack opening has been completely closed or sealed, by means of a barrier device which prevents the free pass age of a powdered or granular material contained in the sack into the surrounding air through the air channel. Provides a simpler and more economically produced air venting channel which permits only slight escape of the packed material than the air venting devices normally used in such sacks or bags.
