Patent FR-2231446-A1 (FR)
Title: Cam controlled press with reciprocating feed bar - has vertically reciprocated press block and roller driven bar
IPC: B21D43/02
Filed: 1973-05-28
Abstract: The pressing-machine has a die against which the sliding block is pressed to shape the metal. The block has vertical slots through which a cross-bar can have reciprocating movement. This horizontal motion is synchronized with the up and down motion of the block, to feed the lower die with metal plate to be worked and to extract the finished part. The coordination of these two movements is achieved mechanically. Each cycle of the block's vertical movement corresponds to a complete rotation of a cam while the alternating cross-bar movement is achieved through a roller and a rod moving parallel to itself.

Title: Fuel supply system for fuel injection engine - controls quantity of fuel in dependence on fuel pressure and engine speed
IPC: F02D1/08
Filed: 1974-05-09
Abstract: The quantity of fuel supplied to the engine is determined by the position of a shuttle (12) sliding in the body of the apparatus. the position of the shuttle (12) is determined by the position of the piston (14) in the cylinder (40). A groove (13) in the side of the piston (14) engages with a projection from the shuttle (12) and so controls the position of the shuttle. The position of the piston depends on two conditions: (A). the pressure from a slide valve controlled by a centrifugal governor (33) driven by the engine. (B). The position of a stop (41) controlled by a piston (42) actuated by the fuel pressure. The quantity of fuel delivered to the engine is thus a function of engine speed and fuel pressure.

Title: Separation of isotopes - by selective radiation and diversion of enriched stream by electric field, economizing in energy
IPC: B01D59/50
Filed: 1974-06-20
Abstract: A method of separating isotopes of elements which can be put into a physico-chemical form in which the isotopic elements of the molecules contg. them can be readily displaced and for which there exist selective radiations absorbed by specific isotopes, or by the molecules contg. from consists of submitting the mixt, insuch a form, to the selective radiation and to an electric field. The positive and negative ions then migrate to the negative and positive electrodes respectively, creating zones where the ratio of the concn. of the isotopes differs from the original ratio. The fractions enriched in one or the other isotopes are then sepd. The form may be a stream of gas at a press. low enough for the mean free path of the ions to be large enough to prevent collisions and exchange of charges or flowing at a velocity low enough for the flow to be laminar. Alternatively it may be a liquid, circulating in a very narrow zone between two porous walls behind which are cells contg. electrodes. The radiation is electromagnetic produced by an electrical discharge in the sepn. zone, mixing being prevented by a screen of gas transparent to the radiation of by filtration through a layer of isotopes. It may be produced by lasers. The field is established by pulses of amplitude and period such that the mean drift of the ions during a pulse is small in relation to the mean free path of the ions between collisions. The selective radiation is established by pulses synchronised with the direct pulses of the field. The technique is very selective. It is not necessary to supply ionisation energy equally for all the isotopes, and this results in lower operating and equipment cost, compared to existing techniques.

Title: Thermoforming thermoplastic panels in groups - by stacking panels with controlled interstitial pressures
IPC: B29C51/00
Filed: 1974-07-11
Abstract: Thermoforming several independent thermoplastic panels simultaneously comprises stacking the panels with intermediate gas tight spacers and then generating a pressure differential on the opposite faces of the stack. Each spacer may incorporate a passage for generating or controlling the pressure between each pair of panels. Alternatively internal pressures may be adjusted by use of capsules or blowing agents, e.g. solid CO2, to keep adjacent panels apart. Some pairs may be mounted on a permanent spacer. Used for the mfr. of single- or double-glazed domes or blisters for e.g. skylights for buildings, and conveniently produces double panels completely sepd. by a spacer of insulating matl. Inter-panel pressure control can create double panels of dissimilar curvatures.

Title: Carrier wave phase modulator - is for two waves in quadrature and uses sampling technique to limit spectral content
IPC: H03C3/40
Filed: 1974-12-19
Abstract: The phase modulation technique is one in which two carrier waves in quadrature are amplitude modulated, each by means of a balanced modulator with an analogue modulation signal, the modulation products being added vectorially. The technique employed suppresses spectral components of an order higher than some predetermined level and hence reduces the bandwidth corresponding to the modulation index and to the modulation frequency. The signals are derived from the cosine and sine functions of the analogous modulation signal by a sampling technique. Cut-off frequencies for the filters are equal to the mean of the sampling frequency, the low pass filters having a nyquist response.

Title: Heat and humidity exchanger - made by winding alternate corrugated and flat layers of transfer medium around hub
IPC: F24F3/14
Filed: 1976-01-16
Abstract: A method of constructing a rotary heat exchanger consists of winding alternate corrugated and flat spiral bands of material around a central core and enclosing them by a metallic rim. The exchanger transfers sensible and latent heat, with or without humidity, between e.g. two currents of air. The corrugations are parallel to the width of the band, and the edges of the bands which form the opposite faces of the exchanger are coated with a layer of chloroprene rubber applied as an atomised liquid and allowed to solidify. The height of the openings formed by the corrugations is 1.4-3 mm and the length of the passages is 100-400 times the height of the corrugations. The layers may be of cellulose paper (84%) treated with ammonium sulphate and diammonium phosphate (16%). The cellulose paper may be bleached Kraft, wt. 4.2 kg/m2, thickness .1 to .15 mm. The layers may be fixed to one another by chloroprene rubber adhesive, metallic layers may be interposed and metal radial suports may be fitted, to give rigidity. The assembly is mounted on a shaft so that it can rotate in the air stream. The exchange medium has desirable characteristics for energy exchange and humidity absorption over a wide range of uses and can be made of different sizes e.g. from 70 cm-3.5 m dia,while the thickness can be maintained within reasonable limits e.g. 60 cm. Press. drop is low and the risk of blockage by solid particles is minimal. Cost is low and resistance to fire and bacterial attack is high. Typically used in recovery devices exchanging sensible and latent heat between fresh air and air from apartments and other premises.

Title: Sliding bearing with separately produced face flanging - fitted and held in position by recess arrangement on bearing bushing
IPC: F16C17/26
Filed: 1976-02-05
Abstract: On split-type sliding bearings with end flanges it is from production point of view an advantage if bushings and end flanges are produced separately and then fitted together before using them on a machine. The end flanges being also in two halves. It is essential that their positions on the bushings are definite without the possibility of a dislocation.
