Patent FR-2242175-A1 (FR)
Title: Continuous forging machine - has eccentric driven hammers which act also as workpiece transporters
IPC: B21J7/18
Filed: 1974-08-30
Abstract: The continuously operating forging machine is used for forging continuous matl. such as bars and rods. The hammers are used to deform the shape of the matl. and the hammers act simultaneously as workpiece transporters. The workpiece is fed forwards, depending on its cross section and length of the bar either only by the oscillating movement of the hammers or by means of a separate transporter roll which acts in conjunction with the oscillating hammers. This machine can forge bar matl. of any length and of any cross section and the matl. is moved in a straight line through the machine. The matl. is not upset. The hammers have flexible guides for their movements in the feed direction of the matl. This flexible guiding of hammers ensures that the hammers penetrating the workpiece matl. do not impart accelerations of the workpiece against the feed direction. The flexible support for the hammers is provided by an adjustable hydraulic system. The machine housing accommodates hammers which are driven by eccentric shafts which are parallel to the workpiece axis. An oscillating movement in the direction of the workpiece movements is imparted to the hammers by the cylindrical guides and by the single gear tooth arrangement.

Title: Solvent sepn. from air using activated carbon - with programmed cycle of adsorption and regeneration to obt. high purificn.
IPC: B01D53/04
Filed: 1975-02-28
Abstract: In a method for removing solvent vapours from air, by activated carbon adsorption and regeneration of the carbon by steam desorption, >=2 activated carbon chambers are used, the sequence of adsorption and regeneration being automatically regulated as a function of the concn. of solvent vapours, pref. by switching from adsorption to regeneration when the concn. of the vapours in the air on the discharge side of the adsorber exceeds a predetermined value. Pref., regeneration is commenced with a very high steam flow, using superheated steam, followed by more moderate flow, then drying. The redn. from high to moderate flow can be continuous or by steps, as the solvent concn. decreases. The number of activated carbon chambers in operation is given by n = (tA - tR)/tA (where tA is adsorption period; tR is regeneration period; and n is > rounded off to the next highest whole number).
Patent FR-2303652-A1 (FR)
Title: Tool handles prodn. from polyurethane foam - with glass fibre reinforcement for reducing flexibility
IPC: B29C44/12
Filed: 1975-03-10
Abstract: Prodn. of tool handles, stakes, posts, piles, etc. from polyurethane foam is carried out by placing in the interior of a mould a reinforcement made of glass fibre-reinforced thermosetting plastic matl., in the form of a tube or any other shape, which is centred within the mould. Pref. the reinforcement has a given porosity to provide greater adherence between the reinforcement and the polyurethane foam and to allow the foam to penetrate the surface of the reinforcement. Apart from reducing the flexibility of the polyurethane foam, which is introduced into the mould after the reinforcement by injection moulding, this method provides a surface reproduced by the mould. The polyurethane foam is thus provided with advantages identical to those of wood.

Title: Level detector for liquid in reservoir - uses transmit-receive pulsed acoustic probe in contact with outside wall to monitor level of reflection of acoustic pulses
IPC: G01F23/296
Filed: 1975-09-18
Abstract: The device described can detect the presence of a liquid at a certain level through the wall of a reservoir. It comprises a transmit-receive pulsed acoustic probe (1) which is placed in contact with the external surface of the reservoir wall at the level at which the presence (or absence) of liquid is to be determined. Acoustic pulses are emitted and these propagate into the wall. Echoes are received due to successive reflections at the internal surface of the wall and at the probe's transmit-receive surface. The echoes received are selected from a predetermined burst and a signalling system (6) is triggered when the selected echoes reach a predetermined threshold amplitude. The echo selection unit comprises two monostable circuits (4, 8) and an AND gate (5).

Title: Mechanical handling of bread slices into rusk toasting oven - spaces out slices for toasting in upright position
IPC: B65G47/26
Filed: 1976-11-25
Abstract: The loaf is first sliced transversely into an assembly of adjacent slices. The sliced loaf is advanced as a unit, in a direction at right angles to its longitudinal axis, until located in a separator mechanism.
