Title: Process which makes it possible to determine if a food product has been irradiated
Inventor: FLEGEAU JOEL
IPC: C12Q1/68
Filed: 1987-07-23
Abstract: The invention consists of a process which makes it possible to determine if a food product has been subjected to an ionising treatment or not. The principle of the method is to separate and quantify, after lysis of the cells of a product, the high-molecular weight DNA fragments and the lower-molecular weight fragments. This separation is performed by allowing the DNA solution to flow through an appropriate filter. The assay of the DNA retained on the filter as well as of the DNA of the filtrate or of the initial cellular suspension, for example by microfluorimetry, then makes it possible to determine the proportion of DNA retained on the filter and to deduce therefrom if the product has been subjected to a treatment. The invention applies to the detection of food products which have undergone an ionising treatment.

Patent WO-8900308-A1 (WO)
Title: Pressure regulator
Inventor: OFFENWANGER WOLFGANG
IPC: G05D16/20
Filed: 1988-07-01
Abstract: A pressure regulator is subjected to the action of a proportional force, for example that of a proportional magnet (10), and comprises a valve casing (11) which has a primary connection (12), a secondary connection (13), and a deaeration connection (14) and two mutually coaxial valve components (15, 35) which are guided in such a manner that they can move in the valve casing (11) and can be sujected to the action of the regulating force (F). The first valve component (15) controls a valve seat (16) in the form of a cup (17) in the valve casing (11) which connects the primary side to the secondary side and closes it in a rest, deaeration position, but which opens it for the transition to the working position. The second valve component (35) rests, in the rest position, as in the working position, on a seat surface (20) of the first valve component (15) and in the region of said surface prevents any deaeration by means of a valve component in the direction of the deaeration connection, but in the position of deaeration and separation from the first valve component (15) opens up the passage between said component and the deaeration connection. The seat surface (20) of the first valve component (15) and the valve surface (22) which co-operates with the valve seat (16) in the valve casing (11) are situated in a common diametric plane, and the seat surface (20) is inside and surrounded by the valve seat (22). The pressure regulator is characterized in that the second valve component (35, 135) has, at the end facing the seat surface (20, 120) of the first valve component (15, 115), a valve seat formed by a cup (36, 136) which enables the second valve component (35, 135) to be placed in essentially linear contact on the seat surface (20, 120) of the first surface element and in that the external diameter of the cup (36, 136) of the second valve component corresponds to the internal diameter of the cup (17, 117) of the valve casing (11, 111).
Patent FR-2626945-A1 (FR)
Title: Disc brake and brake pad which can be used in such a brake
Inventor: DEIT GERARD LE
IPC: F16D66/02
Filed: 1988-02-05
Abstract: In a disc brake including brake pads 22 received in openings 14 formed in a support member 12, the outer edge 34 of the lining carrier plate 24 of each pad includes at least one projecting part 54 received in a slot 56 formed in a caliper 36 overhanging the disc 10. A peg 58 projects towards the disc from each part 54. Thus, in the event of the pad 22 sliding between the support member 12 and the disc 10 when the friction lining 26 is totally worn away, the projecting part 54 comes to bear on the edge of the slot 56 creating a torque bringing a peg 58 to bear on the peripheral edge 10c of the disc. The pad is thus prevented from escaping and the driver of the vehicle is warned by the noise generated by the contact between the peg 58 and the disc 10.

Title: Solution of differential equations using integral transform - by integration over unspecified domain using variable limits which are themselves part of integration
IPC: G06F17/13
Filed: 1988-02-29
Abstract: The computation applies an integral transform to solution of differential or partial differntial equations.  The solution makes use of an integral transform having an indeterminate domain of integration, the limits of integration being variables which themselves figure in the function to be calculated. The kernel of the integral transformation is calculated to obtain a transform of the derivative term of the differential equation in the form of a transform of the function multiplied by a parameter. ADVANTAGE - Allows solution of differntial and partial differential equations which cannot be solved by existing methods and which is suitable for programming language.  Solution does not require application of inverse transform.
