Title: Enhanced NMR detection appts. for explosives - has transmitter and receiver connected to RF coil surrounding sample holder near magnet
Inventor: ROLLWITZ WILLIAM LLOYD
IPC: G01R33/44
Filed: 1979-08-28
Abstract: The apparatus comprises a magnet to produce a magnetic field acting on the comingled first and second atomic elements of the samples which magnetic field has a intensity. A RF coil acts at right angles to the magnetic field acting on the sample. A transmitter is connected to the RF coil to produce a transmitted pulse burst of specified frequency, amplitude and duration acting on the sample. A receiver connected to the RF coil forms an output voltage proportional to the nuclear magnetic resonance response of the nuclei of the first element. A device is for controlling the magnetic field intensity of the magnet to achieve a level selected such that the resonant frequency of the first element in the nuclear magnetic resonance mode is approximately equal to the second element nuclear quadrupole resonance so that the NMR signal at the receiver is enhanced.

Filed: 1979-09-05
Abstract: Dans un four-tunnel de cuisson d'articles en charbon crus 20, comportant des carneaux 12 prolongeant des chambres de combustion 24, on établit, à l'aide de soupapes réglables placées dans des cheminées d'échappement 30 qui sont situées à l'extrémité fermée 24 des chambres de combustion, un gradient de pression sur toute la longueur des carneaux et des chambres de combustion tel que l'on obtient, entre les chambres de combustion et l'espace utile, une différence de pression qui fait que les produits de combustion passent dans l'espace utile en quantités suffisantes pour empêcher la formation d'un anneau de coke, sans entraîner la combustion des articles en charbon.
Patent FR-2436244-A1 (FR)
IPC: E06B3/36
Filed: 1979-09-12
Abstract: The casement (5) of a window is articulated on a fixed frame (1) via turning hinges (2). Each turning hinge (2) is equipped, on the fixed frame, with a T-shaped fastening part (10), the hooking projections (11, 12) of which engage behind the holding webs (13, 14) of an anchoring groove (15). By means of pressure screws which are guided through threaded bores of the fastening part (10) and which are supported on the bottom of the groove (15), the fastening parts (10) are secured to the fixed frame (1). The undercut of one hooking projection (11) is increased by the amount of the undercut of the other hooking projection (12), so that the T-shaped fastening parts (10) can be pivoted into the anchoring groove (15). Inserted in the region of the undercut hooking projection (11) is a resiliently elastic cord which, when the fastening part (10) pivots into the anchoring groove (15), is first compressed and as a result of its elasticity, after the fastening part (10) has snapped in, ensures that the opposite hooking projection (12) comes behind the anchoring web (14) in the desired way. Sliding blocks (6) which are pushed into a holding groove (7) are provided for fixing the turning hinge (2) to the casement (5). The sliding block (6) is equipped with an angled nose (8).

Title: Automatic respirator for anaesthetised patient - has two chambers closed by membranes coupled by spindle to move in synchronism
IPC: A61M16/12
Filed: 1980-02-19
Abstract: The automatic respirator is particularly for use with a patient under anaesthetic and has two or more chambers filled and emptied with each cycle. The chambers determine the composition of the gaseous mixture, and are closed by membranes acting as pistons. The membranes are coupled by a common spindle, so that they move in synchronism. The chambers can be supplied by an expander delivering at a pressure of several hundred K Pa. The expanders are coupled together so that the sum of the pressures remains fairly constant, while the chamber volumes are roughly equal.

Title: Stackable soldered container for preserved meat - uses enlarged flared opening for pressed cover before soldering and shaped to accept base of second container
Inventor: VICH JULIO GARCIA
IPC: B65D21/02
Filed: 1980-12-31
Abstract: The container for preserved meat and fish products is made up from a container (4) which has an enlarged diameter at the top to accept a cover (1) electrically soldered in place. The top of the container is flared and a fold (2) on the edge of the cover (1) clips over the upper rim (3) of the container. The cover is then pressed down to contact the inner tapered face of the container rim before soldering. The depression formed by this method of assembly of the cover provides a space for the base of another container, allowing stacking of the containers. The long contact surface formed by pressing the cover into the flared rim gives reliable sealing and reduces the possibility of lead contamination due to solder leakage into the container.

Patent FR-2482785-A1 (FR)
Inventor: ELINSON MORDUKH ILICH
IPC: H01L29/15
Filed: 1981-05-15
Abstract: The semiconductor memory contains a degenerate semiconductor layer (1) and a nondegenerate semiconductor layer (2) having traps in the energy gap. The conductivity type of the degenerate semiconductor layer (1) is opposite to that of the nondegenerate semiconductor layer (2). Situated between the degenerate semiconductor layer (1) and the nondegenerate semiconductor layer (2) is a dielectric layer (4) capable of tunnel conduction. Deposited on the nondegenerate semiconductor layer (2) is a layer of material (5) which forms a potential barrier with the nondegenerate semiconductor layer (2) and, together with the dielectric layer (4) which is capable of tunnel conduction, prevents the penetration of the charge carriers from the degenerate semiconductor layer (1) and from the ohmic contact (6) into the nondegenerate semiconductor layer (2).
Patent FR-2483812-A1 (FR)
IPC: B23P19/04
Filed: 1981-06-09
Abstract: The device is meant for pressing tight hose couplings in particular containing radially projecting parts for example flanges to pressure hoses or the like for work objects requiring radial, pressing machining. The device has two ring-shaped parts (7, 8) arranged concentrically opposite each other so as to move axially, on the inner surfaces of which have been formed guiding cones which open opposite to each other. Between the said rings have been placed the radial jaws (13) resting on the said cone surfaces, the jaws having been stressed tangentially by means of the springs (18) in relation to each other so that the jaws (13) move in a radial direction when a power device, such as a pressure cylinder, presses the ring-shaped parts axially. The guiding cone surfaces on the said ring-shaped parts (7, 8) and on the radial jaws have been formed in two parts in such a manner that the inner cone surfaces (11, 12) of the ring-shaped parts (7, 8) and correspondingly the outer cone surfaces (16, 17) of the radial jaws (13) act as quick move surfaces and the outer cone surfaces (9, 10) of the ring-shaped parts and correspondingly the inner cone surfaces of the jaws act as pressing surfaces, so that the final stage of the jaws' (13) opening movement or correspondingly the first stage of the press movement take place faster than the actual radial pressing movement or correspondingly the first stage of the opening movement. To each jaw (13) has been attached a radial part (30) to guide the jaw (13) during the radial movement by means of the guiding device (27, 28, 29), which device has been arranged to follow the axial movement of the jaw.

Title: Plate for poultry food dispenser - has centre cone with annular floor and rim deforming to adopt either of two alternative shapes
IPC: A01K39/012
Filed: 1981-07-21
Abstract: The plate (10) contains poultry food and is for attachment (15) to an automatic food dispenser (16,17), being of a deformable construction enabling it to adopt either of two alternative shapes (11,12 or 11',12'). The two shapes are used at different stages in the chick-rearing process, using a central cone (11) and an edge wall (13) to define an annular floor (12). The change in shape modifies the floor width and entails pivoting the floor about its internal (19) and external (18) peripheral zones. It uses a catch to hold either shape. The two shapes tend to gather the food by the rim and at the foot of the cone respectively, and the former aligns the floor with the conical walls. The floor is 2.5 mm thick in a semi-rigid material, such as plastics.
