Title: Production of vermicular graphite iron
Inventor: MENK WERNER
IPC: C22C33/10
Filed: 1985-03-18
Abstract: In a process for the production of cast iron with an intermediate structure of vermicular graphite, a GGG melt (for making cast iron with spherulitic graphite) is used as a starting melt, preferably produced in a converter whereby there are constant sulphur and oxygen amounts. Sulphur is additionally mixed with the melt in accordance with the formula:
 S = A.Mg - B, wherein,
 S = added amount of sulphur-containing material based on pure sulphur in % by weight,
 Mg = magnesium content of the starting melt in % by weight,
 A = magnesium factor: 0.9</=A</=1.2,
 B = sulphur constant: -0.02</=B</=+0.05. 
<??>The addition of sulphur to the starting melt is such as to increase the magnesium/sulphur ratio present in the starting melt so as to lie in the range 2:1 to 1:1, whereby the spherulitic graphite is converted into vermicular form.

Title: Detecting scene changes in visual information
Inventor: BLANK GERHARD
IPC: H04N19/179
Filed: 1985-04-17
Abstract: Picture information from an input composite signal FBAS is processed line-by-line in a signal preparation unit 1 and scanned in synchronism in a store 2; the average luminance values of groups of lines are compared with those of corresponding groups in the following field or frame and, upon a substantial jump in the difference values (which is indicative of a change of scene), a scene change pulse is emitted via an optocoupler 5. The system may be employed in an electronic colour correction process for films and video recordings; alternatively it may be used in a security system for monitoring movement by means of video cameras. <IMAGE>

Patent GB-857551-A (GB)
Abstract: 857,551. Control of A.C. motors. SPERRY GYROSCOPE CO. Ltd. April 10, 1957 [April 27, 1956 (2)], Nos. 13027/56 and 13028/56. Class 38 (3). The rotor of a gyroscope is rotated about a vertical axis by an induction motor having stator windings 22, 24, which are wound so as to correspond with two of the three-phase windings of a three-phase motor. A thermally-operated time-delay switch 25 is open when power is first applied to the windings, the motor then operating as a capacitor motor. When the heat from resistor 26 closes contacts 25 capacitor 23 is short-circuited and windings 22, 24 are connected in parallel. Initially, contacts 28 are closed to short-circuit the winding 27 of a solenoid so that a high voltage is applied to the motor for quick acceleration. After an interval, the heating-effect of resistor 29 opens contacts 28 and the voltage applied to the motor is reduced due to the impedance of winding 27. At the same time, the solenoid operates to move a caging device 7 downwardly away from a ball erector 6 to uncage the gyroscope, and to allow an indicating flag 15 to move behind a rim 20 of housing 4. The disappearance of the flag indicates that the gyroscope is fully operative. The motor is normally supplied from terminals 31, 32, connected to one phase of a three-phase generator. However, if the main generator fails, switches 33, 34, are actuated for taking the supply from an inverter 30 which derives single-phase voltage from a source of directcurrent. The switch 25 may be replaced by one in series with the winding 22 and capacitor 23, or the switch may be dispensed with. In another modification, the armature of the solenoid 11 is mounted on a lever pivoted above the level of the solenoid and parallel with axis 8, an end of the lever being adapted to engage the upper end of member 10. The member 7 may be hinged, relative angular movement of the two parts of the member about the hinge being limited by stop-members. A small projection concentric with the rim 35 of the ball erector housing 6 is arranged to engage plate 9 to keep the rim and plate separated in the fully caged position. Specifications 857,552 and 857,553 are referred to.

Title: Starting control circuits for compression ignition engines
Inventor: PALMER ROY CHARLES
IPC: F02N19/04
Filed: 1986-06-18
Abstract: A control circuit for controlling the operation of a starting aid 11 of a compression ignition engine includes a power circuit 16 which controls the power dissipated in the starting aid 11 and a timer circuit which controls the operation of the aid so that it remains in operation after the engine has started. The circuit includes a one terminal temperature responsive device 22 which is mounted on the engine structure so as to be responsive to the engine temperature, the device acting to determine the length of time the aid remains in operation once the engine has started. A switch 17 is closed when the engine starting motor is energised so that a capacitor 26 charges via this switch. The voltage on capacitor 26 when the switch 17 opens at the end of the engine cranking period depends on the temperature sensed by device 22 and a comparator 23 operator so that the aid 11 remains energised after opening of switch 17 for a period dependent on such capacitor voltage. A further comparator (not shown) may be connected to device 22 to prevent charging of capacitor 26, or discharge it, if the engine temperature is above, or rises above, a predetermined level. <IMAGE>

Title: Thermal camera with vertical scanning
Inventor: FOUILLOY JEAN-PIERRE
IPC: H04N3/09
Filed: 1986-06-19
Abstract: A scanning mirror displaces the image of the scene across and perpendicular to a mosaic of detectors having a plurality of parallel lines L1 ... L4 of infrared detector elements, which lines are staggered so as to obtain improved resolution. The lines L1 ... L4 are associated respectively with charge transfer devices (CTD)s Q1 ... Q4 for the purpose of analysing the scene in the direction of the lines by transfer of the charges generated in the detector elements so producing a serial signal for tv raster display. The signals emerging from the CTDs are retarded by the time interval r1, r2, r3 between these lines, in order that these various signals should correspond to a single line of the scene, i.e. each set of four adjacent detectors in respective lines are combined to give a single scan. Application is to night-time observation systems. <IMAGE>

Filed: 1986-12-22
Abstract: Aqueous suspensions of papermaking fibres and filler are each separately treated with an anionic or a cationic polymer, after which the filler (preferably) or the papermaking fibre is treated with a polymer of opposite charge to that used in the initial treatment. The filler and papermaking suspensions are then mixed to form a papermaking stock, with dilution as necessary before, during or after the mixing operation. This stock is then used to form a loaded paper web in conventional manner. The initial treating polymer is preferably a papermaking retention aid or flocculant, e.g. a cationic polyacrylamide or an amine/amide/epichlorohydrin copolymer in the case of cationic materials or an anionic polyacrylamide in the case of anionic materials. The further treating polymer is preferably an anionic or cationic starch, depending on the charge of the initial treating polymer.

Title: Extruding a plastic tube incorporating perforate reinforcement
Inventor: MOLLER HUBERT
IPC: B29C48/09
Filed: 1987-04-28
Abstract: Process for producing a hollow profile having an incorporated reinforcement, device for its implementation, and hollow profile thus obtained. The hollow profile having an incorporated reinforcement is produced by extrusion. The reinforcement 9 is made from a strip of material 4, for example made from tinplate, which is passed through a profiling system having rollers 5, 6, 7 in order to obtain a tube. A separating station 8 elastically half-opens the slit defined by the two edges of the strip in order to enable a hollow fixed mandrel 11 to be inserted into the reinforcement 9. A closure system 12 associated, for example, with a station for welding the edges, provides the final shaping of the tubular reinforcement 9 before it passes in front of the injection channels associated with a group of extruders 15, 16, 17. It is thus possible to apply, to the inside and to the outside of the reinforcement 9, several layers of curable plastic, preferably mixed with fibres. The layers applied last of all are preferably impermeable to gases. <IMAGE>
