Title: Diagraphy data treatment - for evaluating the hydrocarbon content of underground formations from the water saturation and porosity
IPC: G01V11/00
Filed: 1974-04-29
Abstract: Automatic treatment of well diagraphy data by (a) producing a number of diagraphy measurements of a well representative of the formations traversed by the borehole; (b) combining the measurements in order to obtain parameters (I, II) related to the resistivity of the water and porosity of the formation; (c) combining (I) and (II) to obtain an output parameter which is a function of the porosity of the formation and the ratio of the resistivity of the water to that of the formation, the parameter being, more especially, a function of log(Rw/Rt) where Rw = resistivity of the fossil water and Rt = resistivity of the formation. This enables the evaluation of the hydrocarbon content of a formation from the water saturation (Sw) and the porosity (Circle with diagonal line) which are empirically related to the measured values by the equations F = a/circle with diagonal line m and Smw = F. Rw/Rt, to be determined more accurately by establishing their relationships for the coefficient (a) of the formation factor (F). The 'cementation' factor (m) and the exponent (n) of the water saturation Sw.

Title: Device supplying sand to top of stockpile - has horiz spreader wheel on supply conveyor and below discharge end of conveyor
IPC: B65G69/04
Filed: 1974-11-20

Title: Electroluminescent heterostructure semiconductor device - comprising three layers on a transparent substrate, of partly compensated matls.
Inventor: LEBAILLY JACQUES
IPC: G02B6/42
Filed: 1974-12-24
Abstract: Electroluminescent semiconductor device with heterogenous structure comprising a first epitaxial layer on a substrate, the layer being of first conductivity type and a second layer of opposite conductivity type partially compensated, also incorporates a third layer of partly compensated first conductivity type material having a wider forbidden energy band that the first material, and a localised diffused region crossing the third layer and strongly doped with an impurity giving it the opposite type of conductivity, and ohmic contacts on the diffused region an the first layer. Pref. the thickness of the second layer is less than diffusion path length of the minority carriers in this second layer. This method of doping produces electroluminescent junctions of high efficiency between epitaxial materials, the regions being active over a large part of their thickness with a large number of radiative combinations. The process combines the advantages of using an amphoteric depant with the advantages of heterogenous structure without the obligate surface preparation necessary in prior art. Very small devices of highly localised luminosity can be produced.

Title: Television transmission of colour cine films - uses flying spot scan of continuously moving film with light directed through mirror system and filtering
IPC: H04N3/38
Filed: 1975-01-31
Abstract: In this process for transmitting colour cine-films by television the film is moved vertically at constant speed through a flying-spot scannar (T) which sweeps the film horizontally, through the objective (O). The light beam is then captured by the condenser (C) and thrown onto the dichromatic mirror system (M1, M2), which reflects three beams onto three filters (Fr, Fb and Fv). These transmit the three primary colours used in the television signal onto three photomultipliers (Pr, Pb and Pv), and use the resultant signals to modulate a transmitter, or to operate the video-frequency circuits of a receiver.

Title: Moulding tool for plastic and rubber expanded prods. - dispenses with inserts for the air valves, making prodn. cheaper
IPC: B29C49/58
Filed: 1976-05-26
Abstract: A tool for the production of mouldings of rubber or synthetic material which is pressed in the tool whilst in the plastic condition and inflated by compressed air, is built up from a core on which two radially displaceable mould sections are arranged, and a bush enclosing the core which can be displaced axially relatively to the core. At one end of the bush and or mould half, a projecting lip is provided which fits into a corresponding recess in the mould half or the bush, and the bush can be moved from a position in which the cutout is filled by the lip to o one in which the lip is withdrawn part way from the recess. At the height of the cutout, there is a valve in the core connected to a compressed air line, and the valve is fitted in a radially extending bore where it is held in the closed position by a spring-loaded plate in a second bore inclined at an angle to the first. This second bore opnes some distance from the outer circumference of the core into the bore holding the valve, so that the plate loaded by a spring resting with its other end on the head of a screw, can act through the connection of the two bores and engage with a cutout in the valve stem. The tool makes the prodn. of the mould cheaper by making it unnecessary to provide an insert for the valve, a recess in the core for the insert and to cover the cost of their assembly.

Title: Compact drive hub for bicycle - with extension and ball races for free wheel drive tags in bearing groove
IPC: B62M9/10
Filed: 1976-07-09
Abstract: The compact bicycle hub (11) is supported at the one end by a single ball race (12a) and on the other side by a second ball race (24) located on a separate element (6) screwed onto the end of the hub. The separate element and the inside part of the hub provide locating grooves for two smaller ball races (8, 9) which serve to support the chain drive wheels (7) and which also contain the sprung tags (5) of the freewheel drive. The hub is thus made up of a minimum of components and is easily assembled without complicated equipment. It is also repaired easily. The bearing sleeves screw onto the hub, so that both smaller races are adjusted simultaneously whilst the hub bearings have the normal threaded axle.
