Title: Biological treatment of liq. and sewage - with added solid waste, for fertiliser or feed prodn.
IPC: C02F3/02
Filed: 1975-02-13
Abstract: The biological treatment of liq. manure and sewage sludge is carried out by adding a C source comprising a finely divided soid waste product (e.g. straw, sawdust or domestic refuse) until a C/N ratio of >=5:1 (pref. 5-15:1, esp. ca. 10:1) is reached, and intensively stirring and aerating the mixt. in a high-speed stirrer while maintaining a fermentation temp. of 25-40 degrees C and an O2 content of >=0.4 mg/1. The prod. can be used as a fertiliser or as an animal feed. The treatment eliminates strong odours, destroys harmful germs and destroys any weed seeds present without causing the loss os macro- or micronutrients.

Title: Drum filter for removing dust from gases - with compressed air cleaning of filter surface, obviating prodn. interruption
Inventor: CARRASSE JEAN
IPC: B01D46/26
Filed: 1975-03-20
Abstract: A drum filter for removing dust from a gas, e.g. air, has a perforated pipe parallel to the axis carrying compressed air to blow the dust off the surface.

Title: Sliding vane type rotary compressor - has stator in shape of equilateral triangle with rounded corners
IPC: F01C1/344
Filed: 1975-06-26
Abstract: The stator (1) has an inner surface (2) constructed from three straight sections (3a, 3b, 3c) joined by three rounded sections (4a, 4b, 4c). A cylindrical rotor (6) fits tightly to the straight sections leaving working spaces (13a, 13b, 13c) in the rounded sections. Each of these has an inlet port (9a, 9b, 9c) and a discharge port (10a, 10b, 10c). The rotor contains a vane (8) with a sealing strip (7a, 7b) at each end. The vane can slide along a diameter of the rotor and turns with the rotor, sweeping fluid from each inlet to the corresponding discharge port. The distance across the stator along a rotor diameter is the same at all angular positions of the vane and this geometry ensures that the vane remains in tight contact with the stator without the use of springs.

Title: Individual fire escape from high rise building - has cable descent speed controlled by friction spring brakes with centrifugal arms
IPC: A62B1/10
Filed: 1975-07-16
Abstract: An individual fire escape has a housing (1) containing a spindle (2) and a drum (3) carrying the descent cable (4). At the other end is a plate (20) with a hub (6) with inclined slideways (14) cut around its periphery. These retain L shaped spring blades (16, 17) on sliding blocks (13). Each block is connected to a pivot arm (24) having a weight (26) on the end. As the cable unwinds, the blades, supported by a pin (18) under the corner, pass under a roller (22). The friction effect controls the rate of descent. This is regulated by the weighted arms, moving under centrifugal force, altering the relative curvature of the blades.

Title: Marine hydroelectric power plant - has combined hydraulic and electrolytic systems within part submerged caisson
IPC: F04F1/18
Filed: 1976-01-23
Abstract: Power source based on the utilisation of energy stored by a liquid under pressure, the energy being used to power an electrolysis cell. The mechanism is situated within a part-submerged caisson. The caisson has a compartment separated from the main volume by a vertical wall pierced by a valve operated by the hydraulic action of the head of water above, the same mechanism applying pressure to an electrolysis chamber.

A second ledge (6) on the cap is disposed parallel to the first, and arranged so that it clips behind a projection (5) on the container. A groove (7) cut in the outside face of the cap and positioned opposite the second ledge on the inside face reduces the thickness of the cap wall enabling the second ledge to pass over the projection on the neck of the bottle. On the inside of the top of the cap is a cone (8) which wedges into the container neck sealing it hermetically.
Patent FR-2354486-A1 (FR)
Title: Gear drive for rotary furnace - uses idler pinion to reduce hertz stresses in ring gear
IPC: F16H1/26
Filed: 1976-06-11
Abstract: The gear drive to a rotary furance consists of a driving pinion (1) meshing with an idler pinion (3) which, in turn, meshes with the toothed ring (2) of the furnace. The diameter of the idler pinion (3) is three times that of the driving pinion. The toothed ring (2), because of its large size, cannot be heat treated to increase its surface hardness and so it cannot withstand high Hertzian streses. Since he Hertzian stresses vary inversely as the diameter of the idler pinion (3) the stress is reduced by using a pinion of relatively large diameter. The width of the toothed ring (2) can thus be reduced with a consequent reduction in manufacturing cost.

Title: Tyre assembly drum construction - providing adjustment to width plus operating system which eliminates gaps in material lay:up
Inventor: ROITBURD ISAAK SHLEMOVICH
IPC: B29D30/24
Filed: 1976-08-02
Abstract: A laying-up and treading drum for tyre prodn. has sides made up from segments which are mounted on the hollow drive shaft of the drum via a system of arms and are moved together radially by a spindle mechanism inside the drive shaft and press. discs on each side of the segments. These discs move axially along the shaft and operate the arms. Ring plates act as the sides of the drum on the shaft each side of the discs and have radial slots with radially adjustable mountings in them, each end of the mountings projecting from the ring plate is fixed to a segment piece on the drum circumference. All the segment pieces and segments are covered externally with an elastic envelope on to which the layers of tyre material plus bead fittings and tread are applied during the synchronised radial movement of the segments and mountings. Outside each ring plate, elastic elements are located between the projecting ends of adjacent mountings to form the closed face of a drum. Each ring plate can be axially moved relative to corresp. press. discs to alter the width of the drum. Machine prevents formation of voids/gaps and hence creases in the tyre material. It provides adjustment for the drum width.
