Title: Appts. to produce ozonised steam for skin treatment - prevents scalds from condensate and protects eyes from ultra violet radiation
Inventor: BOMBARDIER JEAN-PIERRE
IPC: B01J7/02
Filed: 1980-04-16
Abstract: Appts. for the prodn. of ozonised steam for skin treatment comprises a boiler which generates steam from water. The steam is piped from the boiler, mixed with ozone and applied to the user's skin. The steam delivery pipe now has an orifice cap fitted on its outlet end. Steam passing through the orifice expands inside an outer jacket which surrounds and extends slightly beyond the pipe. Treatment steam is discharged via an aperture in the jacket extension. Pref. the cap is formed with a passage of which the outer end is adjacent to the steam delivery orifice. Steam flow creates a suction pressure in the passage which draws ozone through the passage from a prodn. source within the casing of the appts. Pref. a low voltage incandescent lamp shines through a blue translucent screen to give the discharged steam a bluish tint. The ozonised steam is directed on to the skin where the heat is baso dilatory so that full advantage is taken of the microbiocidal properties of ozone. Scalding drops of condensate are kept away from the users skin. There is no danger to the users eyes from the ultra-violet radiation source producing ozone.

Title: Switching suppression circuit for pulse radar receiver - uses clock circuits and logic circuits to obtain time interval for phase cancelling signals
Inventor: SIRVEN JACQUES MARIE MICHEL
IPC: H03K17/26
Filed: 1980-05-20
Abstract: The procedure eliminates parasitic signals which are generated from the switching of the receiver channels in a radar station by double switching with a defined time interval. The parasitic signals from each switching action are in phase opposition and readily cancel. A switching control circuit is provided and uses two precise clock circuits to generate a time interval via logic circuits and an OR gate. The second clock is controlled from a summing circuit which receives transfer function signals from corrector circuits. Supplementary switches generate parasitic signals which pass via a mixer to control the second clock in a control loop. This loop is broken by a switch if the parasitic signal is outside the range of the receiver filter.

Title: Plastics component esp. handles or fittings integrally formed - onto porous article by direct moulding in thermoplastic state
Inventor: KOPIA FLORENTINE
IPC: B29C65/00
Filed: 1980-11-05
Abstract: A method of integrally forming plastics elements onto porous materials consists of forming, typically injection moulding, a non-polar, partially crystalline plastics material, such as polyolefin, in the thermoplastics state onto the porous material; the porous material itself constitutes one-half of the mould, while the other half of the mould is of smooth metal and follows the desired contour of the injection moulding. The injection moulding parameters are selected so that the molten material penetrates to a sufficient depth into the porous material structure. The method can be used for attaching handles, decorative components, strips and the like to porous articles of furniture etc. No separate prefabrication of the fittings is required.

Patent FR-2477624-A1 (FR)
Inventor: FRANK WILHELM
IPC: E05D15/52
Filed: 1981-02-27
Abstract: A baseplate (2) to be fastened to the fixed frame of a window or of a door carries a bearing block (6). Arranged between the flanges of the latter is an axle pin (31) provided with a thread. A joint pin (34) is mounted on this axle pin so as to be pivotable and axially adjustable. An adjusting pin (16) is fastened in the baseplate rotatably, but so as to be axially non-displaceable. Two supporting pins (7) pass through the baseplate. These are formed in one piece on the lower end of the bearing block (6) and engage behind the baseplate by means of a nose (11). This nose, which is directed towards the lower end face of the baseplate, makes an articulated connection between the bearing block (6) and baseplate (2), about which connection the bearing block (6) is pivotable as a result of the rotation of the adjusting pin (16). The wing pressing force can thereby be regulated.

Title: Astable direction indicator lamp controller for motor vehicle - uses rectified and filtered supply to astable multivibrator to switch relay which alternates supply between front and rear bulb
Inventor: BERNE GIANPAOLO
IPC: H05B39/09
Filed: 1981-08-05
Abstract: The indicators are activated by a two pole switch which connect the indicators on one side of the vehicle to the supply. The flashing of the lamps is controlled by an astable multivibrator having one side a Darlington transistor pair to drive a relay coil. The relay moves a contact which connects the supply to one of two contacts, so the indicator lamps are alternately supplied. The cockpit indicator lamp is alternately bridged and in circuit, so a failed bulb causes a change in its flashing rate. A capacitor is connected to the collector of one of the transistors and is used to short circuit parasitic signals coming from the supply and having a high frequency.

Title: Marking machine for longitudinal insulated electrical wires - uses cassette type ribbon carrier for marking and head to transfer marking to longitudinal element
Inventor: VALLA ROLAND
IPC: H01B13/34
Filed: 1981-09-17
Abstract: The machine employs a marking head which strikes the element to leave a marking on it, whether by impression, adhesion, or welding, and secondly a guide mechanism to transport the element past the marking head. The mark fixed to the element is carried, before it is fixed to the element, by a ribbon mounted in a unit having two winding spools comprising a cassette readily detached from a support. One of the spools is driven so the speed of the ribbon is synchronised with the operation of the marking head so the ribbon is advanced one step with each marking. A detector stops the drive to the marking head if the ribbon is absent or has been stopped by blockage. The marking head assembly has a heatable head which can be rapidly withdrawn from the neighbourhood of the ribbon to permit quick replacement of the cassettes without a risk of burning for the operator.

Title: Solar heated plant watering system - uses pipe from tank to feed tubular stake in solar energy collecting case
IPC: A01G9/12
Filed: 1981-09-16
Abstract: The plant-watering process uses tubular stakes (11) driven into the soil to deliver water to the roots through the point, using a transparent stake-casing (20) to gather solar energy and raise the temp. of the feed. The inner tube is made of material with good thermal conduction properties and a high absorption coefficient. Flow is controlled by compressible permeable material (8) incorporated in the point. The point itself is made of porous non-compressible material with calibrated holes (7) accommodating the discharge, and the associated watering system uses a tank with a float controlled pressure supply to feed a series of stakes by using a distribution pipe and 'T' shaped connectors (13). Photo-resistant cells may be used to vary the tank level according to conditions.
