Patent FR-2241686-A1 (FR)
Title: Gyroscopic method of testing alignment of a borehole - wherein a boring pipe instrumentation case signals azimuth and inclination
IPC: E21B47/022
Filed: 1973-08-20
Abstract: A device for determining the azimuth and any deviation from the vertical in a borehole or pit includes a gyroscope which puts out a signal varying with its orientation relative to the earth's axis of rotation. The dimensions of the gyroscope are such that it can be assembled with other instruments in a case and lowered down the bore. It comprises a rotor and is supported by a motor which rotates the case and the rotor frame on an axis. A clinometer is also supported and turned by the motor so as to generate signals corresponding to its rotation and the degree of inclination of the instruments' axis to the vertical. A circuit comprising amplifiers and a multiplexer circuit processes the signals at predetermined depths for a recorder. Accurate readings of both deviations from the azimuth and from the vertical are obtained without the inconvenience and expense of repeated withdrawal of boring bars and measuring equipment.

Title: Tool carrier for machine tool spindle - is rotary box with chuck and epicyclic gear drive
IPC: B23Q35/00
Filed: 1974-02-08
Abstract: In the neutral position, the cutting spindle plate (21), mounted eccentrically, is in line with the machine spindle. The outer case does not rotate and the drive is through its internal ring gear (13) and a pinion (25) onto the cutting spindle gear (17). Turning the head, using a fitted worm and wormwheel, gives only a speed increase. By moving the plate (21), the cutting spindle (16) becomes eccentric (161) by an amount (d) determined by the angle of movement. The gear train takes up new positions (13, 251, 171). The drive from the spindle is as before. When the worm and wormwheel are rotated, this amount (4) becomes the machined radius.

Title: Corrosion resistant composite coating - formed on steel substrate by series of electroplating steps followed by heat treatment
IPC: C25D5/50
Filed: 1974-05-30
Abstract: Corrosion resistant composite coating is formed on steel by first electroplating the steel with zinc, then electroplating a layer of copper over the zinc, then electroplating a layer of tin over the copper. The composite layer structure is heat treated to obtain an alloy layer between the inter. copper layer and the outer tin layer. The heat treatment is carried out in a gaseous phase or in an oil layer at temp. around the melting point of tin so that the actual temp. of the outer layer does not exceed the melting point of tin. Excellent corrosion resistant properties can be obtained and the plating layer is uniform.

Title: Electrical storage heater - has mass and installed heating power half usual requirements, heat delivery power twice power input
IPC: F24H7/04
Filed: 1974-06-10
Abstract: Electrical storage heater consists of a heat storage mass through which air can flow to remove heat, and which is electrically heated. The mass and the installed heating power are matched to half the usual heat requirements, but the heat delivery power corresponds to twice the power input. Preferably the electrical heating rods are fitted in the flow channels of the storage mass. A temperature sensor is acted on by the temperature of the mass to switch the heater on and off and acted on by an auxiliary heater dependent on the external temperature and with its control power controlled in a falling sense from the beginning to end of the low tariff time. The control power of the auxiliary heater is controlled from the beginning of the high tariff period again in the rising sense, to a maximum at the end of this period. Size of installation and power requirements are optimised.

Title: Probe for obtaining geological data - incorporating sleeve for applying gas pressure to expel residual liq. after use, facilitating removal
IPC: E21B49/00
Filed: 1976-11-25
Abstract: A method of facilitating the removal, from a hole drilled in the ground, of a probe having a wall which dilates under the press. of a liq., and used for ascertaining the characteristics of the ground, consists of subjection the expandable wall to a counter-pressure of gas to drive out the residual liq. A sleeve is placed around the dilatable wall of the probe and the space between the sleeve and the wall is connected by a pipe to a source of gas under press. After the liq. has been driven out the gas is purged. Any remaining liq. lodges in a cavity sufficient for the residual expansion of the probe to have no effect on its ease of removal. Probe is used to obtain information about the ground in which the hole has been drilled, by measurements of the variations of vol. and press.
