Title: Wear blocks for vacuum boxes on band filters - have support elements, with cooling fluid channel, that move elastically to contour of filter band
IPC: B01D33/00
Filed: 1975-04-30
Abstract: Wear blocks that are part of a vacuum box and that support the filter belt of a band filter have >1 deformable element allowing the upper part of the block that actually supports the belt to move following the inclination of the belt. These upper elements have a longitudinal channel filled with a fluid that reduces the press. exerted by the belt on the edges of the blocks and also carries away the heat produced by friction between block and belt. The upper element may be rigid and be connected to a fixed lower rigid element by 2 flexible sheets or 2 elastic or pneumatic elements that seal a compartment which allows the upper support element to move. This compartment is filled with the same fluid that is in the channel of the upper element of the block and is connected to this channel by a conduit. The channel in the upper element can be wider or narrower than the deformable compartment, the latter form giving no fluid leakage past the support edges of the element. If the former arrangement is installed the connecting conduit between the compartment and the upper element is fitted with some means of regulating the press. loss between the two. When the deformable compartment is sealed by elastic or pneumatic elements stops are fitted to the opposing faces of the upper and lower rigid elements to limit the movement of the upper element. The blocks are used as an integral part of a vacuum box on band filters to support the band. Balanced fluid cushions, are obtd. supporting the belts directly and the assembly equalises automatically the pressures of contact of the 2 edges of the wear block.

Title: Sealed vessel filling appts. - has jet medium drawn in at lower pressure downstream of jet inside pipe
Inventor: BOUVIER DANIEL
IPC: A47C27/08
Filed: 1976-03-01
Abstract: The equipment fills a sealed vessel with a medium, being particularly for inflating tyres, boats, etc. It has an air flow passage in which there is a jet (10) of smaller section than the passage itself (8). The inside of the passage downstream of the jet is connected to a medium whose pressure is less than that used for filling the vessel. The result is to draw in air by an ejector effect and greatly increase the volume delivered into the vessel, in addition, to giving automatic protection against excess pressure. The additional air can be admitted by a port (F) formed in the passage.

IPC: E06B11/00
Filed: 1976-05-14
Abstract: The safety device is for personnel working at the receiving stations of a goods lift. It has a barrier, shut automatically when the lift is not present at the station concerned. The barrier can be formed by a screen accommodating the lift, with two barriers opposite or at right angles to each other. The barriers can be interlocked so that one is open while the other is shut, and vice versa. Each barrier can comprise a bar, with fittings on it, folded against when it is raised into the open position. Means can also be provided for protection against shock loads due to oscillation of the load, between lift platform and screen when the platform is at the receiving station.

Title: Load positioning equipment using balloon - has ropes from support hauling load-supporting frame vertically downwards
Inventor: PORTIER SERGE
IPC: B64B1/00
Filed: 1976-09-20
Abstract: The equipment accurately positions on a support, a load carried by a dirigible balloon. The load is suspended below a frame (3), supported at one point (3a) by the balloon (1) via a hoist (36) slipping under overload. The frame is balanced so as to remain horizontal, and positioned accurately above the point at which the load is to be set down, using a set of ropes between three or more anchorage points (32, 34, 35), not in line with each other, on the support and outside the setting down point, and other such points (18-21) on the frame itself. The lift exerted by the balloon is adjusted so as to keep all ropes taut but to a value less than that needed to cause the hoist to slip. The ropes are then wound in simultaneously with forces whose resultant is greater than the slipping load of the hoist. This hauls the frame vertically downwards onto the support, keeping it horizontal in the process, until the load is set down.

Title: Installation to purify waste water in continuous flow - through passage into which reagents are injected upstream of static mixers
IPC: C02F1/52
Filed: 1977-03-18
Abstract: The liq. is passed through a passage of constant cross-section. Reagents are injected into the passage at spaced locations. Downstream from each injection location, static mixer elements on the interior of the passage wall create turbulence to provide good contacting between waste water and the injected reagent. Turbulence results from flow of the waste water itself through the passage. The passage pref. follows a zig-zag path made up of a number of parallel, straight runs of pipe joined by return bends, A static mixer section is pref. fitted after each return bend. The passage is pref. a tube of circular cross-section. The static mixer elements are pref. helical vanes which can be right-hand and/or left hand in combination. Useful e.g. for coagulation, flocculation, pH adjustment etc. Very efficient contacting of waste water with reagents is ensured without any need for moving agitators. Turbulent mixing is achieved by the liq. being passed through static mixers.

Title: Automatic mass measurement balance - uses opto-electronic detection of movement of moire fringes resulting from mechanical movement
IPC: G01G23/36
Filed: 1977-03-22
Abstract: A mass is measured in a balance in which an optoelectronic system detects movement caused by the mass. This movement causes modulation of light to produce movement of moire fringes which is sensed by an optoelectronic system. A balance (10) has a platform (14) to support a load and which moves vertically on a plunger (16) on which crank arms (18, 20) are mountd to pivot to produce linear movement of the platform. A moire optoelectronic transducer (38) slides n vertical guide shafts (34, 36) between base pieces (26, 28) on the detector (12). Platform movement is transferred by a shaft (52) to move the transducer. This modulates light beam to cause movemnt of moire fringes measured by photoele ctric cells.

Title: Average temp. measurement over time period - is achieved by integrating current from temp. probe thermistor
Inventor: BECKER MICHEL
IPC: G01K3/04
Filed: 1977-03-25
Abstract: During ecological studies of a region the average temp. over a period is required. This is obtd. by integrating current from temp. probe thermistor. The integration is performed by counting pulses from a relaxation circuit. A relaxation circuit comprises a transistor (10) emitter follower with a capacitor (12) in the collector circuit. The thermistor (2) is connected into the base resistor circuit. A unijunction transistor (18) connected to the capacitor switches rapidly when a threshold charge level has been reached to discharge capacitor into a resistor (19). The duration sepg. the pulses is inversely proportional to the capacitor charge current making the frequency of recurrence linearly proportional to temp. Pulses are counted (3) by an electromechanical counter (32) triggered by a thyristor (30).

Title: Turbine power output enhancement method - has pump which accelerates flow of fluid supplied to turbine
IPC: F03B1/00
Filed: 1977-03-25
Abstract: The power output from a turbine can be increased by using a pump to accelerate the flow of fluid supplied to the turbine. It is claimed that the power to drive the pump is less than the extra power produced by the turbine. The pump inlet duct (5) converges as it approaches the pump (1) and thereby accelerates the fluid flowing to the pump. The pump (1) may be driven directly from the turbine (2) or may be provided with a separate power supply. The duct (5) and the combined pump (1) and turbine (2) may be installed in a barrage or dam.
