Title: Metal transfer redn. in dinitrogen tetroxide coolant systems - by addition of nitric oxide
Inventor: SHPAK V S
IPC: G21C15/28
Filed: 1976-02-27
Abstract: A coolant for a power plant comprises 97-99.5 wt.% dinitrogen tetroxide and 0.5-3 wt.% nitric oxide. The coolant is prepd. by reacting a predetermined wt. of N2O4 vapour with molten alkali metal nitrite at 270-550 degrees C. The wt. of N2O4 is 1-115 times the wt. of alkali metal nitrite used. Used esp. for single circuit nuclear power plants, where N2O4 is the working fluid in turbines. Transfer of metal along the circuit, with attendant risk of cooling channel clogging and transfer of radioactivity, is reduced by a factor of 70-100. For operation under subcritical conditions, the coolant pref. contains 0.5-1.5 wt.% NO; and for supercritical conditions, pref. 1.5-2.5% NO.

Title: Fibre optic connector with end fittings - has end fittings for each fibre, alignment support slots and pressure elements
Inventor: ROCTON LUCIEN
IPC: G02B6/38
Filed: 1976-03-08
Abstract: A fibre optic connector is described which comprises an end-fitting for each fibre end, an alignment support, and pressing elements. The end-fitting comprises a capillary tube fitted with a shoulder at a defined distance from one of its ends. The terminal face of the fibre is kept coplanar and centralised in this tube. The alignment support has one or more transversal slots or grooves inside it which receive the ends of two fibres each equipped with an end-fitting. The shoulders of the two end-fittings are kept up against the extreme edges of the slot, thus ensuring a predetermined gap or spacing between the terminal faces of the two fibres. The pressing elements partially cross the connection support and emerge from the same side and perpendicular to the inside of each slot, thus ensuring that the two end fittings are against the opposite edge of the slot in which they are kept and also ensuring their axial alignment.

Title: Rotary internal combustion engine - has cam formed on surface of rotating piston to actuate sliding vanes
IPC: F01C1/356
Filed: 1977-01-18
Abstract: A rotary internal combustion engine has a cylinder (1) housing a rotating piston (2). The piston (2) has a cam (5) formed on its surface such that there is only a minimum clearance between the tip of the cam and the bore of the cylinder (1). As the piston (2) rotates, a mixture of air and fuel is drawn in through the port (12) and when the cam (5) has passed the port (12) the mixture is compressed and forced into the combustion chamber (6). The cam (5) operates the sliding vanes (8) which trap the mixture in the combustion chamber where it is ignited. The gas formed by combustion expands and exerts a force on the radial face of the cam (5) to drive the piston. The exhaust gases then pass out through the port (10).

Title: Strong-room combination lock - has inner and outer knobs to rotate notched cylindrical bearings to engage with locking lever arm
IPC: E05B37/12
Filed: 1977-03-02
Abstract: The combination lock is for a strong-room door, having on the outer face one or more knobs for the selection of the opening combination while there are an equal number of knobs on the inside. A locking mechanism incorporates a lever acting as a bolt. Each assembly formed by an inner and outer knob has two cylindrical coaxial bearings, one fixed to an inner and one to an outer knob, and each with a radial notch which must be brought into alignment with an arm corresponding to the lever to open the lock. The bearings are locked so as to turn together by connectors such that selection of the corresponding part of the combination by turning the knob in a particular direction brings one notch at least into line with the lever arm.
Patent FR-2382692-A1 (FR)
Title: Determining distribution of chemical element in sample - by comparing X=ray transmission images for sample at wavelengths on each side of element absorption line
Inventor: LOWENTHAL SERGE
IPC: G01N23/06
Filed: 1977-03-04
Abstract: A parallel beam of monochromatic X-rays is passed through the sample and the transmission image produced is recorded, e.g. by a photosensitive plate or a scanning point detector. Images are produced at wavelengths above and below the X-ray absorption line for the element to be located. A comparison of the two images enables the distribution to be determined. The X-ray beam can be produced by a synchrotron, and a filter may be used or a monochromatic operating on the Bragg reflection principle. For large samples, the images can be recorded for several angles of incidence of the beam to enable depth distribution to be deduced. The technique is not limited by sample thickness, whereas existing non-destructive techniques are suitable only for samples of about 1 mu m. It is not necessary to operate under vacuum for wavelengths of 4 angstroms and biological samples can therefore be analysed.
