Title: Cooling system for disc brakes - uses aerofoil type wings on disc extension to create flow of cooling air
IPC: F16D65/12
Filed: 1974-01-14
Abstract: The disc carrier (6) is mounted on the rotating shaft and the disc (1) is mounted at its inner periphery to axial extension legs (61) radially equispaced on the carrier. Also clamped to those legs is an inward extension (12) to the disc carrying aerofoil type wings (14) on each side. The wings create a cooling airflow over the disc via an inlet (5c) and an exhaust (9). A thermostat (10) switches in a booster inlet turbine in the case of disc overheating. Drag due to pumping of air is thus minimised in normal operation when little or no braking is performed, but adequate cooling is still available when it is needed.

Title: Reversible cycle heat pump - distributor valves change flow for summer or winter operation combined with water and air temp control
IPC: F25B13/00
Filed: 1974-07-17
Abstract: The heat pump for a house includes an evaporator, compressor, slide valves and distributor system so that a refrigerant is pumped around a circuit which can be changed over from a system for summer use to a system for winter. In winter, a triple flow air circulation system is employed, so that air is extracted from e.g. the kitchen and W.C., and passed through the evaporator before discharge to outside, while air taken from living rooms etc., passes through the condenser for reheating, and mixing with fresh air then fed back again into the same rooms. In summer this cycle is reversed, the evaporator becoming the condenser and vice versa. A combined water and air circulation system can be used where the heat pump can supply heat to the water, or when the water becomes too warm, the heat pump extracts heat from the water.

Title: Prepn. of strips of pasty materials - such as chewing gum by extrusion onto moving belt
IPC: A23G7/02
Filed: 1975-04-30
Abstract: The extruder is provided with a pivoting arm carrying the extrusion die. The pivoting arm sweeps a certain angular sector of the belt so as to deposit the extruded material in the form of a fillet as the belt passes into the cooling zone. The movement of the arm must co-operates with the travelling belt so that the fillet of extruded material is deposited in a regular sinusoidal form. The speed of the belt must be accelerated at the level of the curves and slowed down in the rectilinear parts of the fillet. The movements are co-ordinated in a control box. The plant is simple and has a high yield at a comparatively low cost. The automatic passage from the mixer to the cooling post is effected without causing any deformation of the deposited fillet from the extruder.

Patent FR-2340576-A1 (FR)
Title: Dual control system for a solar energy furnace - comprising two independent systems to keep constant the relative position of the mirrors to the sun
Inventor: DEFLANDRE JEAN
IPC: F24S23/70
Filed: 1976-02-09
Abstract: Installation for the recovery of solar energy comprising numerous heliographs placed on the ground reflecting the sun's radiation and concentrating it towards a focal point in a furnace situated on a tower. The installation includes two control systems, the first being an arrangement allowing the automatic pursuit of the sun in its apparent movement across the sky. The second system comprises an electronic programmer which controls the movement of the heliographs when absence of sunlight prevents the automatic pursuit system from working. Each heliograph has a principal moveable mirror and a second small mirror fixed solidly to the main mirror. The second mirror reflects radiation to a secondary focus, this beam operating the mechanism which keeps the relative position of the principal mirror to the sun constant. The beam from this secondary mirror is received by four diametrically opposed lenses of television cameras placed at the periphery of the light spot. When the beam moves so that one or more of the lenses is outside the light spot the correcting mechanism operates. The use of a secondary smaller beam to operate the control mechanism makes the use of optical receivers possible. An automatic pursuit system operating alone necessitates large corrections after periods of cloud and after the darkness of the night. This can result in a time lag during which sunlight is wasted.
