Title: Tractor mounted seed and fertiliser spreader - has hopper, partition, feed wheels, fan and ducts
IPC: A01C7/08
Filed: 1975-05-22
Abstract: A machine to distribute a mixture of more than one material, the mixing of the various components taking place in the machine itself, has a frame with tractor hitching points (2) and a hopper (3). A partition (4) surmounted by a hinged plate (6) divides the hopper. At the bottom of the hopper is a line of openings (8 & 8'), for each compartment (7, 7'), shut or partially shut by slides (9). Distributor wheels (10) in housing (11) are driven at an adjustable speed and feed the materials into a small hopper (12) for feeding into ducts (14) connected to a fan (15) through ducts (16), constricted at a point (17) just before the hopper outlet orifice (13), causing a lowering of pressure which sucks the material out of the hopper (12). The main hopper may have several sub-division.

Title: Double walled ice cube bowl - has half shell with insulating inner shell and protective outer shell
IPC: A47G23/04
Filed: 1975-06-24
Abstract: The double-walled spherical ice cube container is made from two hollow spheres split into hemispheres which fit snugly one inside the other. The outer shells may have variegated window cut-outs which reveal the inner shell. The inner shell is of insulating material and the outer (4) of more robust material for protective purposes.

In this case the windows (5) in the outer shell may have a specific geometrical arrangement which gives the assembled container the aspect of a panelled football.
Patent FR-2280416-A1 (FR)
Title: Filtration of solutions through moving band filters - with filter panel as alternative filter if band is ruptured
IPC: B01D35/16
Filed: 1975-07-28
Abstract: A filter for solns. from washing operations or machine tool cooling, incorporates a band moving through a filter zone and fed from above by the soln. and has a channel under the edge of the band to receive any unfiltered overflow, an outlet chamber through which the filtered liq. passes, and has one wall which is a removable filter panel. If the band is ruptured, this panel acts as the main filter. The chamber also contains a float operated switch which interrupts the flow of soln. when the residues build up in the chamber. The filter band is an endless band carried on chains and several scraper blades are provided to remove the impurities, into the filter vessel, and to move them towards an outlet. Alternatively, the filter may operate intermittently, and the feed may enter through a chamber, the edges of which are hollow and flexible, so that they make a fluid tight joint with the band, and the soln. may be charged under forced circulation. The filter is more efficient, and more accurate than existing fillers, because it eliminates the risk of feed liq. and filtrate being mixed, for example by the filter band becoming perforated or the feed overflowing at the edges.

Title: Automatically closing air-duct concertina fire-protection flap - with springs at paired lamellae's hinged edges sectioned for tension when folded
IPC: A62C2/16
Filed: 1975-07-29
Abstract: The automatically closing fire-screening flap, as used in air-conditioning and ventilating ducts in buildings, comprises a series of metal sheets or other lamellae, hinged together edge to edge and normally folded zig-zag wise in a stack, and mounted on one side of the duct, where they are held by a retainer which melts at a critical temperature to release the spring stressed lamellae into the blocking position. A spring (8) is fitted in the area of each connecting edge between two lamellae (12), with sections in it connected to the adjacent lamellae in such a way that the springs are stressed when the lamellae are folded together to a stack. This ensures that the requisite spring force is made available.

Title: Blow moulding appts cooling system - with dried air supplied to the mould system during moulding operation
IPC: B29C49/48
Filed: 1976-01-05
Abstract: Blow moulding machine has a core rod support which moved core rods successively through a parison injection station, a blowing station, and a stripping station. A blow mould at the blowing station has a mould cavity in which the core rods carrying parison extend so that the parison can be blown, and a cooling chamber in the mould through which cooling fluid circulates. An air conditioner removes moisture from air which is then supplied to the exposed surfaces of the mould at the time of discharge of a blown article to prevent sweating of the surfaces. The system shortens the time that the core remains in the blow mould since the moulding becomes self supporting more quickly allowing cycle time to be reduced at the prodn. rate increased.

Title: Immobilisation of enzymes - by reacting their amino gps. with halogenoamide gps. contained in a carrier
IPC: C12N11/06
Filed: 1976-01-30
Abstract: Enzymes, in particular alpha-amylase papain, trypsin or invertase, are immobilised by reaction with cpds. contg. halogenoamide gps., pref. chloroamide gps. which chemically bind amine gps. contained in the enzymes; this reaction takes place at pH 7-11 in a temp. range from -10 degrees to +50 degrees C. Immobilisation of the enzymes greatly facilitates processes based on enzymatic reactions. By the above method, enzymes are firmly attached to carries and their activity is only slightly decreased. The process is relatively inexpensive.
Patent FR-2313817-A1 (FR)
Title: Electric power switching circuit - has output transistor whose collector-emitter path is connected between supply wire and output wire
IPC: H03K17/0814
Filed: 1976-06-04
Abstract: There are means for control of current intensity applied to the output transistor control electrode for its switching between conducting and blocked states. There is a return wire and a choke inserted into one of the wires. There is a further choke in series with a diode, inserted between the output wire and the return wire, and there are means in parallel with the further choke for derivation of its stored energy. When the transistor is blocked the output current is maintained by the energy released by the first choke. When the transistor is made conducting, energy stored in the further choke sustains the voltage of the output wire, so that voltage across the transistor collector-emitter path is reduced.
