Abstract: SYSTEM TO CONTROL AND SUPERVISE VEHICLE TRANSIT IN THE PUBLIC PARKING AREAS, consisting of the implementation of hardware and software permitting at the entrance of a public car park, the association of the radio-frequency identification device code located in the vehicle with the ticket dispatched or the used card. At the car park exit, this system permits to detect ticket and/or card exchange between different vehicles and accordingly to prevent the theft of a vehicle by using a ticket or card different from that related to said vehicle. Likewise, it detects and prevents the execution of fraudulent operations derived from exchanging tickets and/or cards.

Abstract: A composition for topical application to the skin, contains an active principle with irritant character in a cosmetically or pharmaceutically acceptable vehicle, in which the vehicle contains more than 5% by weight of peroxidized vegetable oil having a peroxidation level of between 5 and 600 milliequivalents per kg. The presence of the peroxidized oil reduces the irritant character of the principle, particularly capsaicin and retinoic acid.

Abstract: A cosmetic composition containing an extract of the plant Terminalia catappa is found to be useful for combating skin ageing and the phenomena of irritation, inflammation, allergic reaction and hyperpigmentation. It also has been found to have a slimming effect and is useful in the treatment of freckles.

Abstract: An evoked response audiometer method and apparatus in which a patient receives an auditory stimulus signal comprising a carrier frequency which is periodically amplitude modulated and frequency modulated whereby the stimulus is at least substantially frequency specific, the brain potential signals of the patient evoked by the auditory signal being sampled to determine whether phase locking to the modulated auditory signal has occurred, the auditory signal being selectively controlled to advance or delay one modulation with respect to the other modulation to cause enhancement of the evoked response to the auditory stimulus.

Abstract: An aluminum bloom more than 99.95% pure is obtained by segregation of aluminum from an impure parent liquor. Heat supplied to the parent liquor during growth of the bloom is adjusted as a function of the height of the bloom.

Abstract: Process for conveyance of a powder material in a hyperdense bed to bypass an obstacle, in which an obstacle bypass device including at least upstream, intermediate and downstream caissons is inserted between two horizontal conveyors, an upstream conveyor, and the downstream conveyor. At a device entry, at the upstream caisson lower duct is supplied with gas at pressure P1, the upstream caisson further including an upper duct which is a column. The intermediate caisson is between the upstream caisson and the downstream caisson at a level that bypasses the obstacle, a lower duct of which is fed with gas at pressure P3 and an upper duct of which is connected to the upper duct of the upstream caisson and to an upper duct of the downstream caisson. At a device outlet, at the downstream caisson, a lower duct is supplied with gas at pressure P2. The three caissons remain full of powder material kept in a potential fluidization state at all times, with a pressure difference P1−P2 being kept strictly positive.

Abstract: The present invention concerns a container of the type made up of a receptacle (2) hermetically containing a product (3) in a liquid, gas or pasty state to be distributed, an end piece (4) for distributing the product (3) and means for protecting the distribution end piece (4). The means for protecting the distributor end piece (4) are made up of a sleeve (8) able to slide freely on said end piece (4) by means of activation means (9A, 9A′, 9B, 9B′) belonging to it so that said sleeve (8) automatically ensures protection by covering the end piece (4) when the container (1) is placed, or on the other hand freeing it under solely the effect of the inertia of the sub-unit (8-9-11).

Abstract: A rigid support structure comprising a plurality of beams having slots, a plurality of holding elements having a plurality of tabs extending therefrom, each of the tabs including a slot complementary to said slots in said beams, said holding elements being mounted on said beams with said tab slots engaging said beam slots; wherein two tabs are received in at least one of said beam slots.

Abstract: In order to acquire data for an image representation which shows the spatial distribution of the magnetic resonance behavior of an object within a selected localized region, the relevant localized region is arranged in a stationary magnetic field and is subjected to a sequence of high frequency pulses and pulses of magnetic field gradients in different spatial directions, such that a succession of magnetic resonance signals appears. These signals are read out by scanning under the influence of a read gradient and are used as sets of data for the filling of the K-space. In accordance with the invention, at least two different sequences of high frequency pulses and magnetic field gradient pulses are used, which differ in at least one of the features of the signal creation responsible for different aspects of the image quality. These sequences are executed one after another in time, with the magnetic resonance signals read out for the different sequences being collated in different bands of the K-space.

Abstract: This invention relates to a convertible head support for use by a child or an adult, particularly in an automotive vehicle, comprising a support (1) and a flap (2) hinged on the support around an axis (6) that is essentially horizontal from a high user position for an adult to a low user position for a child, said flap comprising a support body (11) that is generally flat and that on one of its faces has a head support surface for the adult and on its other face a head support surface for the child. The flap comprises two lateral flanges (12) that are essentially vertical and that extend from the edges of the support body (11) on the side of its face presenting the head support surface for the child and the support body (11) and the two lateral flanges (12) are complementary to said support (1) so as to fit around the support when flap (2) is in the high position.

Abstract: A method for preparing acetic acid and/or methyl acetate by simultaneous isomerization and carbonylation reactions. A reaction mixture is provided containing at least one reagent which provides formyl radicals and at least one further reagent which provides methyl radicals, together with water in an amount of at most 5% by weight, carbon monoxide at a partial pressure between 0.1·105 Pa and 25·105 Pa, a solvent and a catalytic system which contains at least one halogenated promoter and at least one iridium-based compound. In a typical reaction mixture, methyl formate is isomerized to form acetic acid according to the reaction: HCOOCH3CH3COOH while methanol undergoes carbonylation to form acetic acid according to the reaction: CH3OH+COCH3COOH The reagent which provides the formyl radicals is kept at or below 20% by weight of the reaction mixture, while the molar ratio of methyl radicals to formyl radicals in the mixture is greater than 1.
