Title: Polytetrafluoroethylene
IPC: B02C19/06
Filed: 1964-11-03
Abstract: Ultrafine polytetrafluoroethylene is prepared by subjecting polytetrafluoroethylene particles having no dimension less than 100 microns to milling effected substantially solely by interparticle collision at a temperature below 200 DEG F., and classifying the milled particles to separate therefrom particles having their maximum dimension not greater than 50 microns, wet sieve size. Unseparated particles may be resubjected to milling and classification, and interparticle collision may be effected by the accelerating influence of jets of inert gas. The process may be effected in a mill having the shape of an elongated vertical toroid, the curved upper and lower ends of which are joined by parallel vertical sides, the polymer and inert gas being introduced at the lower curved end, and classification occurring at the upper curved end. The products may be moulded and sintered to form shaped articles. Many physical properties of the products are specified.

Patent ES-348784-A1 (ES)
Title: Solvent filter particularly designed for dry-cleaning plants
IPC: B01D29/39
Filed: 1967-12-29
Abstract: A plurality of vane-shapedfilter elements D are secured to a common shaft F so that when the latter is rotated, portions of the solvent present in the chamber B are subjected to centrifugal motion and (by reaction against the chamber wall) centripetal motion, whereby the elements D are cleaned of accumulated dirt. The vane-to-housing separation 100 increases circumferentially. As described, the filter elements are similar to those of Specification 1181273 and the device operates similarly. As shaft F rotates (after filtration), the solvent is urged outwardly (arrows V, T) into space 100 until it meets baffle plate 112, which is axially longer than the elements D and so directs solvent radially inwards, arrows U (Fig. 1, not shown). It may be used as a dry-cleaning machine filter.

Title: Associative memory system which can be addressed associatively or conventionally
IPC: G11C15/04
Filed: 1968-01-11
Abstract: Each word in a matrix associative memory has a unique address field. Each word in the transistorized memory has an erasable data field and a read-only address field, the address fields specifying the word locations and thus being all different. An input register has a data field and an address field, and by masking off one of them an associative search may be done on the data fields or the address fields, the matching word or words being read out to an output register. The output register also receives an indication of the number of matches (0, 1 or a plurality) provided by logic fed by the output of the address fields since in the case of more than one match at least one address bit position will be indicated as being both 1 and 0 (on separate lines) and in the case of no match any particular bit will not be indicated as being either.

Title: Safety device with an inflatable cushion which provides effective protection during successive collisions
IPC: B60R21/2346
Filed: 1973-01-15
Abstract: A safety device with an inflatable cushion for moving vehicles, particularly automobiles, comprises at least one inflatable cushion, means for expanding and re-expanding the said cushion and a collision detector controlling the actuation of such a device, the cushion being equipped with means for transferring gas in both directions, at two different flow rates, between the surrounding atomosphere and the inside of the cushion, the gas exchange taking place at a low flow rate in the direction from the inside of the cushion to the surrounding atmosphere, for the purpose of deadening the person to be protected when the latter is thrown against the said cushion during an accident, and at a higher flow rate in the direction from the surrounding atmosphere to the inside of the cushion for the purpose of rapidly re-inflating the said cushion as soon as the latter is no longer acted upon by the person to be protected. The device is particularly effective in case of a series of impacts, because it is partially reversible and dissipates a part of the energy by absorbing gas and absorbing the rest of the energy to restore the device to its initial state before a new deadening of the person to be protected.

Title: Yoghurt-making machine
IPC: A23C9/12
Filed: 1974-05-22
Abstract: A yoghurt-making machine comprises an enclosure inside which a receptacle containing milk pots is disposed above a basin. The space between the receptacle and basis is partly filled with a fusible material, such as commercial paraffin wax which has a cooling curve exhibiting a solidification plateau at a temperature near to the optimum temperature of yoghurt formation. A heating resistor attached to the basin is immersed in the fusible material which is thereby heated. The basin has a bottom defining with the enclosure a closed chamber completely separated from the fusible material. A temperature-limiting element is connected to the resistor and disposed so as to be responsive only to the air temperature within the chamber and is operable to terminate the heating of the fusible material when the temperature in the chamber is higher than the solidification plateau of the fusible material. The amount of the fusible material is sufficient for its solidification plateau to be maintained during subsequent cooling throughout the duration required for the formation of the yoghurt.
