Title: Hot water boiler for domestic heating - has horizontal water tubes through hearth at bottom of combustion chamber for rapid warm up
IPC: F23J15/08
Filed: 1976-01-30
Abstract: A water boiler has a rectangular casing with double walls (4) which form a water jacket round a central rectangular combustion chamber. There is a grate (9) in the lower part of the combustion chamber on which solid fuel is burnt. Water enters through a connection (1) in the lower part of one side of the boiler and flows initially through horizontal tubes (3) placed close above the grate (9). This takes the water through the hottest part of the flame and ensures rapid heating without cooling of the flue gases. The water then enters the jacket and leaves from the top of the side of the boiler. The flue outlet (7) has an inlet (5) for preheated air which dilutes the gases and prevents condensation.

Patent FR-2346281-A1 (FR)
Title: Self-lipting platform for use at sea - has free-wheeling dampers for the swell and cushioning blocks
IPC: E02B17/08
Filed: 1976-03-29
Abstract: A self-lifting platform has a rack forming the corner of one of its legs, and acts through pinions controlled by couplings secured to a beam. The beam is fixed to the platform on damping details, and these which act as guides are arranged between the vertical surfaces of the platform and beam whilst between the horizontal surfaces blocks of rubber are placed. When a self lifting platform is installed or its position changed, and when there is heavy wave action unusually heavy shock loading can be imposed on the lifting mechanism during the sinking or lifting of the legs. Particularly when the legs hit the sea bottom, they are lifted and dropped much more rapidly by the waves, than the normal operational lifting and lowering speeds. These shock loadings are damped and their number is reduced by an arrangement in which the beam carrying the rack is attached to the platform by elastic packings such as rubber blocks. This dampens the shock when the legs hit the bottom, whilst the hammering on the seabed is prevented by two couplings on each pinion which allow the leg to fall relatively to the platform, whilst preventing the platform falling relatively to the leg.

Title: Extracting shale oil from oil shale - using pyrolyzer receiving heat carrier from combustor in which carbon on spent shale is burned
IPC: C10G1/02
Filed: 1976-06-18
Abstract: Shale oil is extracted from oil shale by separating a finer fraction from the raw shale feed and preheating the remaining larger soze fraction by contact with finely-divded hot shale ash and hot gas coming from a fluidised bed spend shale combustor. The preheated shale fraction is separated from the ash and fed together with the fines fraction to a pyrolyzer which receives a finely-divided heat carrier from the combustor and a supply of hot fluidisation gas. Heat carrier and smaller spend shale particles leaving the pyrolyzer are separated from the larger spent shale particles and are fed direct to the combustor while the larger spent shale particles are fed to the combustor via pulveriser.

Title: Safety circuit for washing machine, permanent magnet motor - uses counter EMF to close interrupter shunting diode pump
Inventor: HERBET CLAUDE
IPC: H02H7/08
Filed: 1977-06-24
Abstract: Safety device is fitted to the drive control circuit of a domestic laundry washing machine; the permanent magnet motor being fed by a rectified current with cyclical commutation, which is variable by thyristors. The triggers of the thyristors are connected to a relaxing circuit formed by a time constant network, working with two transistors of complementary polarities arranged head to tail. A circuit known as a "diode pump" is located between the base of the transistor connected to the time constant network, and a common conductor feeding pulsed current, connected to one of the motor terminals. This circuit is shunted by an electronic interrupter, the control electrode of which is connected to the other terminal of the motor. The electronic interrupter is a transistor in the emitter of which a zener diode is inserted; the emitter forming the control electrode of the interrupter. The base of the interrupter-transistor is connected through a resistance to the common feed of pulsed current for the control circuit. The capacitor of the diode pump circuit is shunted by a resistance. Used to protect the motor against burning out, in the event, say, of the door not having seen fastened correctly, and opening to allow items from inside to become trapped and block the motion of the drum. The induction current is then reduced immediately to a safe level, and this is achieved at comparatively little expense relatively to the motor control circuit. Protection can thus be extended to machines at the cheaper end of the market.
