Title: Liquid de-aerator with meter - applicable to collections of milk from farms by tanker lorry
IPC: G01F15/08
Filed: 1972-10-06
Abstract: A de-aeration chamber, to which liquid, e.g. milk from a farm reservoir, is pumped through a tangential entry, has a bottom outlet for fluid, and a top outlet for air, and is equipped with a float, which, at a min. fluid level, actuates a switch in circuit with a magnetic valve, so that compressed air forces a valve in the chamber air outlet closed (against a spring) and forces a valve in the chamber fluid outlet line open (against a spring). Chamber air and fluid outlets are connected to the top and bottom respectively of a tank, e.g. on a lorry, and the fluid line has a meter and non-return valve. Accuracy of metering and quality of fluid is ensured, by prevention of air entrainment in fluid line.

Patent FR-2223135-A1 (FR)
Title: Machine attachment for shaping, slotting or filing - translates rotary machine tool motion into reciprocating motion
IPC: B23Q5/027
Filed: 1973-03-29
Abstract: A shaft, rotated by the machine, has a spiral track machined in its surface. A sleeve fits over the shaft and carries the cutting tool. Between the shaft and the sleeve is a ball follower running in the spiral track. The sleeve is prevented from rotating by balls in splines running axially along its length. When the shaft rotates, the follower moves the sleeve up and down, giving reciprocating motion. An outer case completes the unit. The track is formed as a double helix whose oppositely extending paths extend halfway around the shaft.
Patent FR-2230921-A1 (FR)
Title: Wire reinforced pipe for powders etc. - internal undulations prevent clogging of powder by inducing spiral flow
IPC: F16L11/112
Filed: 1973-05-23
Abstract: The pipe is made from rubber, plastic or similar material (2) and is reinforced by a continuous helix of round metal wire (1). The wall thickness of the pipe is increased locally around the reinforcing wire and reduced between successive coils of the helix. This results in the internal wall being provided with longitudinal undulations (3). As a result, a spiral motion is induced in the flowing powder which minimises the possibility of pipe blockage due to clogging of the powder. The pipe is particularly useful for supplying powdered material to electro-static spray guns.

Title: Large block mould esp. for expanded polystyrene - withstands steam pressure but is quickly opened to remove block
Inventor: BUCHMANN RUDOLF CHRISTIAN
IPC: B29C33/28
Filed: 1974-11-07
Abstract: A prismatic mould of rectangular cross-section is used for making blocks, esp. very large blocks of an expanded plastics esp. polystyrene. The mould is desinged to withstand internal fluid (steam) pressure and is constituted of two parts which are permanently connected together by two hinge joints, one or both of which comprises an eccentric. Thus, rotation of these eccentrics enables the two parts to be moved apart sufficiently for the moulded block to be withdrawn from the mould. Pref., each part is an angle-section and they move relative to each other along a diagonal of the cross-section of the mould. Esp. in modern processes for the prodn. of very large expanded polystyrene blocks, where an initial steam pressure of 5-10 kp/cm2 is used. The arrangement enables the mould to ge safely kept closed against this pressure, while enabling it to be readily opened for the block to be subsequently removed, before contraction has taken place.

Title: Removing volatile heavy metals esp. zinc in steel mfr. - using e.g. the converter or electric arc furnace
Inventor: VAYSSIERE PIERRE
IPC: C21C5/38
Filed: 1975-04-18
Abstract: A process for removing volatile heavy metals from products used during the various stages of the mfr. of steel is described. The material contg. these metals is charged at the beginning into a furance equipped with a hood for the recovery of flue gases. These gases are treated to remove dust and obtain a by product rich in heavy metals. Flues gases given off in subsequent operations are treated in a second dust-removal unit separate from the first to give a product rich in Fe but low in heavy metals. Undesirable heavy metals esp Zn are removed. The furnace used for producing the steel is itself used to separate the heavy metals. A Zn-rich fraction of high commercial value can be obtd.

If the container has double glass walls the development can be followed in inactive light, moreover the end of the developing process can be viewed in the chamber in normal lighting. Heating of the liquids accelerates the development which can be of the order of 90 seconds. Drying air can also be introduced into the chamber. The development machine has a chamber (C) in which the film is placed, a developing circuit with pump (Pr) a heated reservoir (Rr) and two valves. It has a rinsing or washing circuit having two valves and a fixing circuit with pump (Pf) a reservoir (Rr) and two valves.

Title: Dishwashing machine operating system - uses water after rinsing to regenerate water in main washing tank
IPC: A47L15/16
Filed: 1975-09-19
Abstract: The machine has an initial and main washing stage and a rinsing stage. The interchangeable washing basket (2) remains in the same place in the main wash chamber. The water used for rinsing is afterwards delivered to the main wash water tank to regenerate the main wash water, and after re-use of the latter it is fed to the initial wash tank to generate the water in the latter. The rinsing water can be drawn from the mains. Water from the spray jets (3) can fall into a guide trough (9), tilted so as to deliver it into either the initial (7) or main (5) water tank, dependent on which tank water is to be drawn off from.

Title: Batten for shuttleless loom - of lighter weight to allow greater speed of operation of loom
IPC: D03D49/62
Filed: 1975-12-17
Abstract: Batten for shuttleless loom comprises a reed of which the dents outside the zone of action of the temples onto the warp threads are made of plastics matl. Pref. they are made of plastics reinforced with fibres. The wt. of the batten is thus reduced by =50% compared with that of a wide batten having dents made exclusively of steel for which the zone of action of the temples is relatively small. The matl. of the dents provides sufficient strength and elasticity to allow biassing of the end dents in the weft direction due to contraction of the fabric.

Title: Large bales material sling - comprises flexible strips sewn together to form base rectangle and corner loops with straps
IPC: B66C1/18
Filed: 1975-12-24
Abstract: Thesling-type container is formed by a number of strips of strong and flexible material, sewn together to form a rectangle with two diagonals across it. External loops at the corners (1) are made from the extensions of the rectangle sides (2, 3). Each loop is completed by a strip (5) sewn in place to form an end ring, and to each of these strips a further strip is attached, forming a strap joining onto the diagonally opposite loop via an eye (8) on the end of one of the straps (6, 7). Thus when placed round a bale the rectangle portion bears against the base, the loops againsts the sides, and the additional strips and straps against the top. The ends of the loops act as rope bights for engagement by lifting hooks etc.
