Title: Combined thermal catalytic recuperative exhaust gas burner - has gas permeable catalyst for exhaust and burner gases
IPC: F23G7/07
Filed: 1974-04-22
Abstract: The recuperative exhaust gas burner uses reduced amounts of thermal energy for burning of contaminants. This burner has a gas permeable catalyst cylinder (12) which encloses a combustion chamber with burner flame. The annular space (5) outside the catalyst forms a heat exchanger with axial pipes (4). Contaminated exhaust gases enter axially in a direction against the flame and treated exhaust gas leaves the burner through a lateral outlet (16). Contaminated gases enter axial pipes (4) arranged between the outer shell and the catalyst. These pipes duct the exhaust gases to the other, flame end of the burner where they are entrained by the flame.

Title: Wind driven turbine with vertical axis - has blades pivoted by rotor rotation mounted between two discs
IPC: F03D3/06
Filed: 1974-11-13
Abstract: The turbine rotor consists of upper and lower discs joined together by rods, and aerofil blades pivoting on vertical shafts mounted between the discs. A lever mounted below each blade carries a roller which runs in a circular groove eccentric to the rotor. As the rotor rotates, the angle of inclination of the blades, with respect to the rotor radius, is changed to give maximum aero-dynamic efficiency. The rotor is shielded on one side by a curved housing so that the blades moving against the direction of the wind are not exposed to it. The rotor is mounted on a platform which is aligned to the wind by a vane.

Title: Symmetrical acrylonitrile-aromatic olefin copolymers - in which olefin is dosed controllably into acrylonitrile aq. suspension contg. hydroxyethyl cellulose/PVP
IPC: C08F2/00
Filed: 1974-12-20
Abstract: Copolymers of 50 - 95 (pref. 86-93) mole % acrylonitrile with >=1 conjugated aromatic olefin (I) with greater reaction speed, such that monomer proportionation is uniform along the chain length, are prepd. by polymsn. in aq. suspension, using hydroxyethyl cellulose (II) or polyvinylpyrrolidone (III) as suspending agents and by dosing the olefin to the reaction mixt. at a rate linearly proportional to the polymsn. speed of the acrylonitrile portion. (I) is acenaphthylene, indene, coumarone or Ar-C(R)=CH2 (where R is CH3 or H; Ar is aromatic (un) substd. residue with =3 rings contg. =4C in substituents). (I) is pref. styrene or alpha-methyl styrene. (II) has a M.S. value, (mole ethylene oxide combined per mole cellulose) of 1.5-3.5, pref. 2-3.5, a D.S. value, (number of OH gps. substd. per anhydroglucose unit), of 1-3.0, pref. 1.5 - 3.0, and a Brookfield viscosity, (as 1% aq. soln. at 25 degrees C), of 500 - 5000, pref. 1000-3000 cP; and (III) has Fikentscher K value >60, pref. >=80. The copolymers are used as moulding cpds. alone or mixed with up to equal wt. of a polydiene rubber. The uniform spread of monomer components along the chain minimises disadvantages of block copolymers, esp. where acrylonitrile blocks are terminal. The suspending agents avoid generation of oversize particles which hinder uniformity and clarity of the mouldings.

Title: Supply control for polyphase asynchronous motors - provides protection against damage due to single phase failure using balanced impedances
Inventor: THOREAU FERNAND
IPC: H02H7/09
Filed: 1975-02-28
Abstract: The system is used for control of the supply to polyphase asynchronous motors. The control arrangement is intended to monitor the motor condition, such that failures of a phase, causing damage due to eddy currents, overheating etc. are detected. The control is arranged through a series of balanced impedances which are associated with the supply phases and there is a comparator circuit similarly fed from the motor phases via capacitors. The comparator, into which the neutral line feeds, provides a cut out function if the balance of the motor currents is upset. The monitor arrangement of the comparator has an input low frequency LC filter and a transistor circuit which is protected against overvoltage. The threshold level at which cut-out occurrs is adjustable by means of a potentiometer.

Title: Anti pecking cover for bird beak - extends over upper beak and is secured by pin
IPC: A01K37/00
Filed: 1975-03-21
Abstract: The cover is designed to prevent cannibalism amongst fowls or game birds during intensive rearing without in any way damaging the beak or causing discomfort to the bird. The stiff plastic cover, in the shape of the upper part of the beak, is attached to the upper part by a pin (7) which passes through one of a number of holes (according to the size of the bird) in the false beak and through the nostrils and nasal septum. The cover can move in relation to the upper beak, pivoting in the securing pin. The cover protrudes beyond the real beak and allows the bird to feed normally while preventing it from attacking other birds.

Title: Rotary vessel for extracting and fermenting grape juice - has discharge opening cover which can be operated while vessel rotates
IPC: B65D88/54
Filed: 1976-04-15
Abstract: A horizontal cylindrical vessel, rotatable about its longitudinal axis and provided with an opening in its shell for loading and discharging the contents. During rotation of the drum, the opening is normally closed and sealed by a removable cover. The cover-opening and closing operations can now be remotely controlled quite independently of the rotary motion of the vessel. Both opening and closing operations follow automatically sequenced stages. To open or close, the cover pref. slides on a guided path longitudinally w.r.t. the opening. More partic. the cover travels on rollers provided with guide rails. During its main longitudinal movement, the cover should be supported clear of the opening. At its 'closed' end of the travel, the cover approaches and is finally clamped against the edge of the opening. Longitudinal travel of the cover and clamp operation are pref. achieved by fluid power cylinders. Used for the extraction and fermentation of juice from fruit etc., partic. from grapes for winemaking. Cover movements can be made while the vessel is rotating. The cover can be opened and closed while the opening is at its lowest position. This is very useful when discharging or cleaning very large vessels.

Title: Corner insert for mitred hollow, frame members - is plastics hinge eleent with interlocking projections forming corner plug
IPC: F16B7/04
Filed: 1976-05-06
Abstract: A plastics insert is used to connect hollow mitred frame members at corners. The insert is formed in two halves (2,3) joined along the corner line by a film hinge (4). Staggered projections (5, 6) with opposed raised portions (51, 61) interlock when the insert is bent along the hinge line and deform, to stiffen the joint. Tongues (21, 31) project away from the corner and are made with rounded edges so that insertion in the hollow frame members (8, 9) is assisted. Varying tolerances in the frame sections are accommodated by forming triangular section ribs (7) increasing in thickness towards the hinge. These ribs increase the resistance to withdrawal of the insert from the frame sections.

Title: Electricity generator drive mechanism - uses interacting magnets to provide driving force for turning generator shaft
IPC: H02K53/00
Filed: 1977-02-14
Abstract: The electric generator has fixed and moving magnets, and uses the attractive and repulsive forces between them to provide the driving force for the generator. Moving magnets (1, 2, 3) are mounted on platforms (30, 31, 32) mounted on ball bearings, and connected to a central shaft (50) which drives the generator.

Title: Silk screen printing plate with metal filled mesh - and electrolytically deposited mask layer of controlled thickness
IPC: B41C1/14
Filed: 1977-04-21
Abstract: A silk screen printing plate comprises a metallised or metallic silk whose meshes are mechanically filled with a metal. The filling may be effected with a metal melt, a suspension of a metal powder in a binder comprising a non-polymerisable resin in a solvent, a low melting alloy in paste form or a thin metal foil. After applying the metal the whole is then calendered or compressed to bring the metal surface flush with the sieve yarns. The filled silk is then electrolytically covered with a different metal of controllable thickness, which is then selectively etched with a solvent to expose the metal in the silk screen meshes. These exposed zones are finally removed with a solvent which does not dissolve the silk yarns. The thickness of the electrolytically deposited layer comprising the mask proper can be precisely controlled.
