Title: Shutter for controlling car heating or ventilating system - has thin sheet with foamed plastic sealing surface reinforced with wire frame
IPC: B60H1/00
Filed: 1975-11-27
Abstract: The shutter for controlling the flow of air in a car heating or ventilating system is assembled from three parts. A thin sheet of metal or rigid plastic (1) is turned up at its edges (1a, b). The sheet is then enclosed in a layer of foamed plastic (2). A frame (3) is formed from wire bent to form a series of U shapes arranged in alternate directions. The ends of the frame (3) fit in the turned up edge (1b) and are secured by protuberances formed by local deformation of the wire. The frame is extended at one end to form a handle (3c). The foamed plastic covering (2) forms a sealing surface over the air outlets of the ventilating system.

Title: Junction piece for mitred joints - has overlapping slots forming spring assembly compensating for width tolerances in frame sections
IPC: F16B12/50
Filed: 1976-01-13
Abstract: This junction element for the mitred corners of door and window frames constructed from hollow rectangular section tubes consists of a one piece aluminium alloy moulding (1) which can accommodate various dimensional tolerances and is particularly suitable for machine assembly of the frames. The moulding is generally L-shaped and has a slot (7, 8) cut in each limb and extending substantially towards the corner (6). Another slot (9) extends from the corner into each limb of the moulding but staggered laterally by a small distance from the two other slots. This arrangement of slots forms a spring dividing the original L- into two parallel portions. If the width of the hollow frame sections should vary, the spring action can be arranged to compensate the variation. Grooves (5) in each limb of the L- locates on internal projections in the walls of the frame sections to retain the junction piece in position.
Patent FR-2338086-A1 (FR)
Title: Cyclone for sepg. particles from gas - with partial obstruction in outlet, eliminating air pulsations and consequent vibrations
Inventor: REBOURS ALBERT
IPC: B04C9/00
Filed: 1976-01-16
Abstract: Cyclone separator, for removing particles or droplets from a gas, is fitted with a partial obstruction in the gas outlet. The obstruction has a specific profile and isolates, from the external air, the central zone of the body of the cyclone, which is at a press. below atmospheric, and its extension into the outlet. The outlet has a convergent-divergent form. Vibrations which originate in the outlet, are suppressed, where low frequency pulsations (1-5 cycles/s) are propagated upstream and downstream of the appts. causing the whole structure to vibrate. There is an axial zone in the outlet which is at low press., connecting the low press. zone in the separator body with the outer air. The outer air is drawn in and mixes with the peripheral gas stream moving axially and rotating about the axis. This entry is not continuous, but pulsatory, causing the vibrations. The obstruction prevents the vibrations by filling the axial zone so that the gas can only flow downstream.

Title: Switch with pivoting lever in housing - has hairpin shaped contact spring cooperating with lever plunger in rocking or slide motion
IPC: H01H23/12
Filed: 1976-01-20
Abstract: The pivoting lever has at its end at least one pointed plunger, and the bottom of the housing carries at least two clamps.

Preferably the contact spring has a straight lower shank, extended on one side by a section shaped like an inverted L. The transition from this shank to another one is rounded, while the other free end terminates in a V-shaped section. The contact spring may be a plate with an upwards bent flexible section.

Title: Rechargeable gas electrode - based on PTFE and carbon for use in electrochemical generators
Inventor: FEUILLADE GEORGES
IPC: H01M4/86
Filed: 1976-04-02
Abstract: A rechargeable gas electrode is produced by (a) mixing an aq. suspension of a hydrophobic agent (esp. PTFE) and carbon powder prepd. by dissocn. of CO, the PTFE and carbon being in the ratio 32.5-48:67.5-52, (b) partly eliminating water by vacuum filtration or evaporation, (c) compressing the mixt. under 40-250 kg/cm2 pressure for 10-100 min. (pref. 250 kg/cm2 for 50 min) in a grill made from an electrically conducting material (e.g. Ni) so that the latter becomes covered with the mixt., and (d) baking at 270-350 degrees C for 30-60 min (pref. 350 degrees C for 30 min). After cooling, the electrode can be directly used in an electrochemical generator, esp. one based on zinc and gas. The electrode is used to consume oxygen and discharge and release it under weak polarisation on charge. The performance of the generator, esp. in relation to voltage and output, depends, other things being equal, on the efficiency of such electrodes. Only dendritic carbon, prepd. by dissocn. of CO in presence of Ni, Fe or Co as catalyst, gives rechargeable electrodes with optimal properties. If such electrodes are subjected to alternate charge and discharge with a current of 10-20 mA/cm2, they generate a potential of 700-800 mV w.r.t the hydrogen electrode which remains constant even after up to 1500 charge-discharge cycles.

Title: New railway track and sleeper laying train - carrying spaced sleepers and rail sections, with sleeper layer and rail roll-off
Inventor: BOYER JEAN-JACQUES
IPC: E01B29/05
Filed: 1976-08-20
Abstract: The processor for laying new railway track involves a train of wagons carrying roll-off media with rail sections on top for unloading ahead. Each platform also carries layers of sleepers, spaced by underlays. The bottom layer remain raised above the permanent way (1), to permit free lengthways movement of rails. At a set interval there is a sleeper-laying device travelling by support on both sides of the ballast bed (2), and capable of loading a wagon with sleepers in a single process, and laying those of the bottom layer in several processes, then lowering and laying the other layers. This is repeated over a length corresponding to a rail piece. Rail pieces are drawn by winches onto roll-off media, thrust onto the sleepers, and fixed at enough points to permit the train to pass over the track.
