Patent FR-2504228-A1 (FR)
Title: Dynamically balanced crankshaft and connecting rod - has rotating counterweight and secondary connecting rod for second weight
Inventor: GAUDILLAT JACQUES FERNAND
IPC: F16F15/26
Filed: 1981-04-16
Abstract: The mass (M1) is caused to reciprocate by the rotation of the crankshaft (OB) which, alone, would give rise to out-of-balance forces or dynamic imbalance. A second connecting rod (B) is hinged (at B) and connected to a second mass (M2) (at e). The mass (M2) may slide in a crosshead but to reduce wear may be connected by a crank (CD) and allowed to assume a slightly oscillatory movement. A counterweight is mounted on a crank (OE) which extends in a direction diametrically opposite the crank (OB). This arrangement equalises the out-of-balance forces.
Patent FR-2480671-A1 (FR)
Inventor: TAVELLA CORRADO
IPC: B29C53/08
Filed: 1981-04-16
Abstract: The device has a magazine (10, 110, 210) with at least one tubular seat (14, 140, 214) to receive the straight section (11) of a flexible tube of elastomeric material which forms the sleeve which is pulled onto a heated mould core (16) which provides it with its final shape, such as, for example, the shape of a knee profile, a push-in mandrel (17) which enters the flexible tube section (11) in order to centre it, hold it and guide it into the annular space between the seat (14, 140, 214) of the magazine (10, 110, 210) and the push-in mandrel (17), and an annular slide (18) which acts on the section (11) contained and guided in the aforementioned annular space, ejecting it from the seat (14, 140, 214) of the magazine and forcing it onto the mould core (16).
Patent FR-2504442-A1 (FR)
Title: Head for driving timber crate-staple - uses orbital U=section press to bend wire retained by mandrel and pushed away by trailing pusher sliding between legs
IPC: B27F7/28
Filed: 1981-04-24
Abstract: The stapling head is used to make crates, with a cutting and bending press (8,9) which acts with a counter cutter (24) cum wire (27) guide and a retractable wire-retaining mandrel (30). The latter acts with a staple-pusher (10) to which the re-action is provided by an anvil (35) applied to the timber. The bending press may have a 'U' section with the staple pusher fitting between its legs, both components having a curved profile whilst being built onto separate levers (5,6) with a common fulcrum (2). The locus of the profiles coincides with the fulcrum, the fulcrum axis is normal to the staple drive (F), and the axis is offset so that the repose position of the head is outside the swept path of the bending component and the pusher. The drive for the levers ensures sequential action and the bending component leads the pusher.
Patent FR-2504879-A1 (FR)
Title: Multifrequency transmission between track and railway vehicle - uses multiple frequencies with detectors having frequency selective filters to encode range of information
Inventor: KIEKEN JEAN-PIERRE
IPC: B61L3/10
Filed: 1981-04-30
Abstract: The method transmits information between the track and the vehicle running on the track a contact brush fixed to the vehicle and sliding on the rail, and a fixed contact from the communications base to the track. Information is transferred while the brush passes over the trackside contact. The information is transmitted on several different set frequencies, so as the vehicle mounted brush passes over the trackside contacts a set of selective filters allow detection of the short circuiting of the signal path, and absence or presence of a signal at a particular frequency to be detected. By encoding the various frequencies, a range of information is communicated between the vehicle and the track.

Title: Low voltage heated carpet or curtain using mains - uses multiple thyristors supplying respective resistors with sequential voltage pulses having safe time averaged values
Inventor: GIRARD FRANCOIS MARIE
IPC: H05B1/02
Filed: 1981-12-14
Abstract: Heating resistances are arranged on a thin insulating film constituting the furbishing (carpet, wallpaper etc) to be heated. Each resistance is supplied by a thyristor such that the output voltage applied to the resistances contains only half waves of one polarity spaced at given numbers of cycles. The intention is to provide a low time averaged voltage valve. The gates of the thyristors are electronically controlled such that successive triggering pulses are applied to each one in sequence, such that only one thyristor is ever conducting. The controller consists of a mains rectifying diode in series with a voltage resistor charging a capacitor to a value determined by a zener diode. The latter supplies two integrated circuits comprising a BCD decoder and a divider. The gates are connected to the BCD decoder output optionally via an amplifier.
