Title: Automatic parking brakes
IPC: B60T13/74
Filed: 1986-04-29
Abstract: The invention relates to a braking device 1 which is attached to the parking brakes of vehicles. This device is characterised in that it essentially consists of a drive element 2 transmitting a variable mechanical tension to this braking system assembly, under the effect of a supply of energy, from an external source and a sensor 3 capable of detecting these variations in mechanical tension. The elements 2 and 3 interact directly, by way of a set 4 of transmission elements, with the friction linings 5 of the parking brakes. The sensor element 3 acts on the drive element 2, stopping the supply of energy from the drive element 2, when the mechanical tension of the braking system assembly has been reached so as directly to immobilise the vehicle, or if the said tension is practically zero, allowing the parking brakes to be released. The invention relates to vehicles.

Title: Automatic parking brakes
IPC: B60T13/22
Filed: 1986-05-23
Abstract: The invention relates to a braking device 1, relating to the parking brakes of cars. This device is characterised in that it consists of a compact element, essentially comprising a tensioning element 2 and a drive element 3, mounted facing one another and connected to the parking brakes by means of transmission elements, the drive element 3 being controlled by external means, such that, when the electric, hydraulic, or pneumatic flow to the drive element 3 is cut off, the tensioning element 2 provides sufficient mechanical tension for the parking brake transmission elements, thereby correctly immobilising the car, especially when its engine is stopped, a supply of electrical, hydraulic or pneumatic flow to the drive element 3 unclamping the brakes concerned. The invention relates to cars.

Title: Method for processing corks
IPC: B27K7/00
Filed: 1987-04-22
Abstract: The corks are dehydrated, for example by heating in an autoclave 1 at a temperature lying between 120 and 150 DEG C, under a pressure lying between 0.01 and 0.05 x 10<5> Pa, for 90 minutes, which leads to their sterilisation. The autoclave is then filled with carbon dioxide under a pressure of approximately 6 x 10<5> Pa, while continuing to heat, in order to sterilise the corks at the core. A vacuum is then reestablished and the corks are immersed in a bath consisting of a mixture of non-refined beeswax and of pure paraffin, held in the molten state at 75 DEG C, in order to impregnate them with this mixture. Finally, the excess impregnation material is removed by spinning. Use of the corks thus treated for removing the risk of incidents during ageing of bottled wine and for avoiding the "cork smell".
