Title: Marc drying appts. using compressed inert gas - in same wine-making tank, giving improved quality red wine
IPC: C12G1/00
Filed: 1974-06-04
Abstract: Wine-making device for red wines in which, after drawing off the wine in the fermentation tank, a marc is obtd., which is pressed as dry as possible, in the same wine-making tank. The device comprises a self-emptying pressurising tank with a grid which retains the marc after drainage. A pipe is provided for evacuating the different wines which are received in a lower reception tank which has a hermetically sealed cover. A compressor has a reserve chamber of an inert gas, such as nitrogen, with supply tubes leading to btoh wine tanks. The compressor establishes a press. in the space above the marc, and at the same time a reduced press. is created in the space below the marc and in the reception tank for the wine made from the expressed juice. The marc is drained of its wine in a definite time, according to the press. employed. The marc is then removed by tilting the tank, after opening the cover. One device suffices for effecting all the red wine-making operations and one compressor can serve several tanks; pressurisation can be made automatic. The intrinsic qualities of the wine at different stages are improved by the partial vacuum in the reception tank. The wine made from the expressed juice has an improved quality because of low, regular press. prevents undesirable substances from dissolving in the wine. Conventional concrete reception tanks, mounted in the subsoil, can be adapted.

Title: Yarn winding device has bobbin driven by grooved roll - guiding yarn and has roll and bobbin movement to prevent yarn build up
IPC: B65H51/06
Filed: 1975-01-30
Abstract: A yarn winding device includes a bobbin supported on a pivoted arm in driving contact with a helically grooved drive roll, yarn being fed into the groove of the drive roll so that the yarn is wound onto the bobbin in the form of a cross-wound package. During winding, one of the ends of the bobbin and drive roll are oscillated in a direction perpendicular to the plane (pref. vertical) contg. the axes of the bobbin and drive roll, and the drive roll is moved so that the yarn is maintained in the groove, If a yarn breakage occurs the action of the yarn on pref. a pivoted lever causes the lever to actuate pref. a micro-switch to brake the drive roller in a controlled manner. At the same time, broken yarn acting a guide pulley operates a cam which moves an arm carrying pref. a pin to bring the pin into contact with a rubber wheel on bobbin to rapidly brake the bobbon. A build of yarn on the bobbin is prevented thereby, preventing breakage. When breakage occurs the device is shut down quickly.

Title: Focussing system comprising single mobile lens - has projection system with field lens, mirror and objective
Inventor: PUECH CLAUDE
IPC: G11B7/09
Filed: 1975-12-16
Abstract: The optical system can focus a beam of radiated energy from a primary source (101) at a point (P2) of an object (111). It comprises a simple single lens (102) which is movable and which forms a mobile point (P1) of radiant energy of minimal dimensions. This point forms a secondary source of radiant energy for a projection system (105, 106, 107), thus enabling the image of the secondary source to be formed on the object. The projection system has a fixed conveyance. Since the beam from the primary source is parallel and monochromatic, and arrives at the lens parallel to its axis the lens is constructed so that it corrects spherical aberation for its principal focus. The projection system comprises a field lens (103) which reduces the divergence of the incident beam from the secondary source (P1), a mobile mirror (106) which deflects the beam afer it has passed through the field lens (103) and an objective (107) which focusses the deflected beam onto a point (P2) of an object (111). The transverse magnification of the projection system is 20 or more.
