Patent FR-2257920-A1 (FR)
Title: Continuous loop cine film mechanism - has rollers turning film in opposite directions in two opposed positions
IPC: G03B21/32
Filed: 1974-01-16
Abstract: The mechanism consists of guide wheels (1-10) fixed in one plane, two of the wheels (3, 8) on articulated arms (11, 12) tensioning the loop under the action of a spring (13). There are two 190 deg. twists in the loop which cause the lengths of each turn in the loop to be the same, half of the length being on the inside of the loop and the other half being on the outside. Film running through the projector comes off the outside of the loop and is returned to the inside, being tensioned by the guides (25, 26) which control the band drive motor on wheel (6) via microswitches (28, 29). A further microswitch (30) stops the motors in the event of film breakage.

Title: Artificial candle mfg. process - uses melting of tube at end to give effect of wax dribbling
IPC: F21S8/00
Filed: 1974-04-17
Abstract: The system is particularly for manufacturing illuminating lamps, and utilises a tubular component (2), one end of which is melted to give the effect of wax dribling (4).

Title: Agitation of vessels using air lift pump - having gas bell above recirculation tube to reuse gas for pumping forward
IPC: B01F33/40
Filed: 1974-06-06
Abstract: Vessel is agitated by means of a gas (esp air) lift pump located in the centre of the vessel; above which is a gas bell which collects the air rising from the inlet pipe and feeds it forward to a second air lift pump which pumps the liquid to the next stage of the process. In the line between the gas bell and the second lift pump, a flow control mechanism is installed. The vessel can be divided into several sections with liquid feeding from one to the next and with the air from one zone being collected and reused to agitate the zone above before finally discharging to atmosphere. Appts. is useful for agitating slurries suspended in liquids. In multistage operations, it avoids the need for differences in level between stages or the need to stagger the mounting of the vessels. Ensures that a uniform slurry is pumped from each stage and allows a single air supply to be used to mix and to pump forward without the excessive energy required when the recycling pump is given enough head to pump forward the whole recycle. In one form, several stages can be included in a single vessel.

Patent FR-2288790-A1 (FR)
IPC: C22C9/06
Filed: 1974-12-13
Abstract: The copper alloy contains 3 to 12% by weight of aluminium, 4 to 7% by weight of nickel, 3 to 6% by weight of iron and 0.3 to 5% by weight of silicon. The remainder consists of copper and impurities resulting from the manufacture. The silicon and aluminium contents should here obey the relationships % Si x % Al = at least 4 and at most 15, and preferably % Si x % Al = at least 6 and at most 12 (field B of Figure 1). Such a copper alloy can resist the vigorous acid attack, such as occurs in pickling plants, and also mechanical stresses, for example fatigue stress loading. It is therefore particularly suitable for the manufacture of pickling equipment.

Title: Artificial kidney with volumetric control of ultrafiltration - incorporates closed loop circulation and periodic renewal of dialysing liq.
Inventor: GRANGER ALAIN
IPC: A61M1/16
Filed: 1976-03-25
Abstract: An ultrafiltration control appts. for an artificial kidney incorporates a dialysing liq. circuit connected to a first compartment of a haemodialyser. The second compartment is connected to the vascular system of a patient. The two compartments are sepd. by a semi-permeable membrane. The first circuit provides for a constant vol. of the dialysing liq. in circulation. The circuit includes a pump; an extn. zone and valves. The pump circulates dialysing liq. in contact with the membrane. The extn. zone incorporates a bubble-trap with a sight glass, connected to a pump which extracts quantities of liq. equal to the quantity of ultrafiltrate taken out. Two valves control the period feed of fresh liq. to, and discharge of exhausted liq. from, the circuit. Two other valves allow isolation of the part of the circuit passing through the extraction zone and the haemodialyser, from the part of the circuit connected to the source and discharge of liq., while the exhausted liq. is being replaced by fresh liq. The haemodialysis a carried out under optimum conditions because of the high circulation speed and frequent renewal of the dialysing liq. The quantities of ultrafiltrate are under close control and can be determined in advance according to the patient's condition.
