Title: Ball bearing outer race assembly in wheel hub - has collet on race engaging groove inside hub after hub heating
IPC: F16C35/067
Filed: 1975-12-23
Abstract: A double row axial thrust ball bearing (3) particularly for mounting inside the hub (5) of a wheel, has its outer race (4) located by a collet (4") which fits into a groove (5") around the inside of the hole (5') into which the periphery (5') of the outer race fits.

Title: Indoor swimming pool structure - has facing panels and insulation material attached to a framework of columns and beams
IPC: E06B1/64
Filed: 1976-01-15
Abstract: The frame comprises vertical columns and horizontal beams and is for use in the construction of indoor swimming pools. On the outside faces of the frame are grooves extending outwards and into which are inserted screws for assembling the fixing and facing panels, with a layer of insulating material placed between the frame and panels. The insulating layers are held firmly in place by means of flanges on the fixing panels. The screws can be easily and quickly inserted because the flanges enable holes drilled in the facing panels and in the insulating materials to be accurately aligned. It is possible for the insulating material to be placed on the fixing panels prior to assembly so that they can be handled as one unit.

Title: Textile sheet material modifcn. for multi-colour effects - by impregnating with solvent and selective applicn. of plastics
IPC: D06P1/00
Filed: 1976-01-26

Title: Optical relay using variable birefringence element - has electric field applied parallel to direction of light propagation to control birefringence of prism.
Inventor: DUMONT FRANCOIS
IPC: G02F1/03
Filed: 1976-03-22
Abstract: The optical relay employs an element with a variable birefringence controlled by the electrical field parallel to the light propagation direction. This element has a transparent conductive layer on one face and a dielectric mirror and electrodes on the opposite face, cooperating with further electrical and/or optical system to provide an electrical field across the element. The birefringence generated within the element is detected via a linearly polarised light source at the focus of a lens directing a parallel light beam onto the mirror. The focal plane of this lens includes a screen for shielding the images of the light source due to parasitic reflection from the faces of the element. The element is in the form of a prism block with a wedge angle of between 1 and 4 degrees.

Title: Protective device for AC system with unearthed neutral line - uses test current injected between neutral and earth and potential difference compared with mains potential difference
Inventor: GUEGAN GUY
IPC: H02H3/16
Filed: 1976-10-01
Abstract: The protective system for a multiphase AC distribution system with unearthed neutral prevents overheating of the neutral by a "double short" current overload. It reduces the fault current to a safe value and trip the circuit if the reduction is not effected within a preset time. A test current at a frequency differing from that of the mains (this may be direct current) is injected between neutral and earth from a constant voltage source through a limiting resistance, and the potential difference between the neutral and earth is measured at both frequencies. From the difference between these values a criterion is provided for the triggering of an alarm.

Title: Engine driven air compressor mounted on trailer - has double walls and doors to direct cooling air flow and improve silencing
IPC: F04D29/66
Filed: 1977-03-07
Abstract: A portable power driven air compressor is housed in a cabinet (9) mounted on a trailer (6) with two wheels (7).

Title: Examining fissures, partic. in turbine and alternator elements - using radioactive tracer emitting two gamma photons in cascade and using detectors and coincidence circuits to maximise resolution
IPC: G01T1/172
Filed: 1977-04-29
Abstract: Appts. for non-destructive examination of fissures incorporates detectors for the gamma-radiation emitted by a radioactive tracter injected into the vol. occupied by the fissure, and components for treating the signals to determine the position of each point of the vol. The detectors are collimated so as to capture the radiation coming from elementary, almost pin-point, volumes and are sensitive to the two photons of different energy emitted in cascade almost simultaneously by a suitable radio element. Coincidence circuits select the detected signals coming from the photons emitted by the elementary volumes. The invention overcomes difficulties in the examination of fissures in e.g. elements of turbines and alternators, which have forms and dimensions such that existing methodsm using gamma-radiation or echography, cannot give the form and position of the fissure with sufficient precision, e.g. resolution of the order of mm.

Filed: 1977-07-27
Abstract: A bath is reduced to mfr. molten iron and possibly gas contg. H2 and CO, the prim. materials being fine iron oxides, fine solid, liq. or gas fuel, and O2. Fuel is injected into the bath so the latter contains >2% C, whereas the oxide is pref. pre-reduced by a gas (G1) and blown down the outer annulus of a lance onto the bath, O2 being fed through the lance bore. Gas (G1) travelling with the oxide contains sufficient heat to melt the oxide. Gas (G1) is also blown through the outer annulus of several tuyeres into the froth on the bath, O2 being fed through the tuyere bores, each tuyere using a mol. ratio O2/H2 + CO of 0.5. The gas leaving the bath is used for the pre-redn. of the oxide and then washed and H2O and CO2 removed, the resulting gas is used as gas (G1). In the pref. process, the oxides are reduced to FeO, and possibly mixed with slag of forming elements before being blown onto the middle of the bath which contais 3-4.5% carbon. Part of the gas (G1) produced can be used for the conventional mfr. of NH3 by using N2 obtd. during the mfr. of O2 used in the invention.
