Patent FR-2492100-A1 (FR)
IPC: G01N13/02
Filed: 1980-10-14
Abstract: Film-balance which records automatically the surface pressure curves as a function of the molecular area of films spread on the surface of an aqueous solution. The apparatus consists of a trough (1) containing the aqueous solution, on the surface of which floats a frame (2) connected with the barrier (3) by two threads. The film spread in the compartment (A) is compressed by the 'moving barrier (6)'. The pressure measurement system, subject matter of the invention, is composed of a pendulum (B) connected with the barrier (3) and coupled with a displacement transducer (25) working without any mechanical contact. The electrical signals corresponding to the displacement of the moving barrier and to the variation of the pressure are recorded. This apparatus is utilizable in medical, pharmaceutical and biological laboratories. It can be used for the working out of industrial surfactants.

Title: Flat plate electric motor commutator ring mfg. process - has channelled wedge shaped segments cut from copper strip and injection moulding insulation
Inventor: BOUGUIN MICHEL
IPC: H01R39/06
Filed: 1980-12-04
Abstract: The individual segments of the commutator ring are fabricated from a single rectangular copper strip. An undercutting, oblique-sided channel is machined in the strip which is then separated into similar trapezoidal segments by equi-angular alternately inclined cuts. The profiles of the chambers in the segments (1) fit on an annular ring (6) which is made of separated sections thus forming an annular configuration of wedge shapes. The outer faces of the segments are flat. The central metal coupling sleeve, making contact with the commutator plates, is fixed to the rear of the segments in an injection moulding machine. The sleeve has radial projections which anchor the fillet of insulating plastics material which is moulded around the rear of the segment plates. Insulaing material in the mould also penetrates radial gaps between the segments and maintain insulation between segments.

Title: Electron beam irradiation unit - has accelerator with scanning and deflection electromagnets arranged to reduce size and weight
IPC: G21K1/093
Filed: 1981-07-21
Abstract: A unit for irradiating a workpiece (5) includes an electron accelerator (1) with its axis parallel to the plane of the magnetic circuit frame of a deflecting electromagnet (6) located in front of a vacuum scanning chamber outlet window (4). A scanning electromagnet has a bias winding (10) supplied with d.c. to direct the beam to the deflecting electromagnet aperture. A sweep generator has a correction circuits to reduce current change speed in the scanning winding as the beam moves to the most remote edge of the deflecting electromagnet from the accelerator and to increase the speed as the beam moves in the opposite direction. The device can be used e.g. in irradiation of polymer films, hardening lacquer coatings or modifying textiles to create patterns and permits the overall size and wt. of a radiation unit to be reduced with associated reduction in the amount of local biological protection required.

Title: Automatic level control for film processing bath - has conductivity monitor and automatic replenisher, and compensates for evaporation losses from process tank
Inventor: KIRSCH WALTER
IPC: G03D3/06
Filed: 1981-11-24
Abstract: The electrodes (1) provide a passive monitor in the process tank with their output processed by an amplifier and compared with a programmed value in a control unit (3). Any deviation from the control value operates an infinitely adjustable supply pump (4) to pump more water into the process tank from a header tank (5). The system compensates for evaporation losses from the heated process tank. A failsafe control operates a time delay after the process tank is switched on to allow the recirculating pump (8) to mix the process fluids evenly. The system provides constant quality over long periods.

Title: Device for drilling tunnels.
Inventor: HENTSCHEL VOLKER
IPC: E21D9/06
Filed: 1982-09-29
Abstract: The device comprises a hollowing machine endowed with a shield 1 and tubular formwork composed of a front form 3 coupled to the said machine and an inner form 2 which together with the surrounding ground make an annular space 4 into which the supporting concrete is injected. The front form 3 is composed of a ring 5 provided with a sealing means 6 in contact with the shield 1 and the inner form 2. The said ring 5, articulated to the shield 1 by means of hydraulic jacks 7 which are uniformly distributed around the perimeter of the tunnel, is longitudinally guided by means of sliding supports 13 in the shield 1, coupled to the hollowing machine via advancing mechanisms 14 and bears on an adjustable elastic arrangement 18, 20. The hydraulic jacks 7 are used as an arrangement for stabilising the ring 5. For this purpose, on the one hand the forward chambers 11 of the cylinders of these jacks exhibit respectively, on account of the presence of a rod 16 extending the rod 9 of the piston forwards, the same cross-section as the rear chambers 12, and on the other hand the assembly of forward and rear chambers 11, 12 are disposed in a series circuit 17 which is closed on itself.
