Title: Process for rectifying circular panoramic images by means of a glass fibre optic
IPC: G02B6/04
Filed: 1963-10-01
Abstract: 1,008,290. Light-guides. CONTINA BUREAUX UND RECHINENMASCHINEN FABRIK A.G. Oct. 1, 1963 [Oct. 15, 1962], No. 38565/63. Heading G2J. A circular image 1 is converted to a rectangular one 3 by a glass filament optical system having one of the sets of ends of a large number of glass filaments arranged to lie in closely packed sequence in concentric circles in the circular image plane and the other of the sets of ends arranged in corresponding straight lines 5 in the same consecutive order as that of the corresponding consecutive circles. In forming the system, glass filaments, which may have a diameter of 5 to 10 microns, are inserted side by side in the slot of a flat former and one end is bent until the row of filaments forms a circle, the other end remaining flat to form one line. The assemblies of filaments are thus built up in circles from the inside outwards at one end and in consecutive straight lines from the bottom upwards at the other. Since the inner circles are smaller than the outer ones the bottom lines will be shorter than the top ones and to correct this an anamorphotic optical system may be interposed between image 3 and the viewing position.

Title: Improvements in or relating to lathes or other like machine tools
IPC: B23B23/02
Filed: 1930-12-23
Abstract: A composition for forming a hard covering on a lathe or like centre is made from a carbide such as tungsten carbide sintered with a cementing metal such as cobalt.  The tungsten carbide and cobalt, which may be in the proportions of from 97-80 per cent and 3-20 per cent respectively are mixed with about 1 per cent of paraffin and are compressed between dies and moulds at a pressure of about 40 tons per square inch.  The material is then heated to about 1375 DEG  C. in closed carbon tubes in an atmosphere of hydrogen.  The paraffin may be omitted and carbides of other metals of the sixth group of Mendelejeff's table may be used with other cementing metals of the iron group.  The sintering temperature of approximately 1380 DEG  C. is suitable for a composition containing about 13 per cent cobalt.

Title: Repeater for rolling mill
IPC: B21B41/06
Filed: 1957-12-13
Abstract: 821,985. Rolling. MORGAN CONSTRUCTION CO. Dec. 13, 1957 [April 3, 1957], No. 38747/57. Class 83 (4). A rolling mill repeater, comprising a plate having a curved guide groove and a vertical stanchion located within the curve of the groove, has a trap member lying between the groove and the stanchion with a vertical curved surface facing in opposition to the stanchion with a lip extending towards the stanchion at the top of the curved surface. The mill stands and associated apparatus are arranged for the simultaneous rolling of three rods. Two sets of guides 13 and 14 follow the stand 11 and feed twist guides 15 which pass the rods through a repeater 10 to guides 16 and 17 leading to a roll stand 12. A repeater comprises a plate 18 with three grooves 19, 21 and 22 to take the rods and inwardly of the innermost groove 22 is a straight sectioned barrier 25 and four stanchions 26 to 29, each comprising a vertical fixed journal 47 and a rotating member 48. Between the groove 22 and the stanchion is a trap member 31 having a flange 34, a vertical curved inner surface 38 and a lip 39, mounted on the plate 18 by dowels. In operation the rod leaves the mill stand 11 in oval form with its major axis horizontal and the twist guide 15 then causes the axis to become vertical to enable the rod to bend in passage through the repeater groove. As the loop of the rod shortens between the stands due to the higher speed of the stand 12 it causes the rod to rise out of the groove 19, slide across the plate 18, up the inclined surface 34 of the trap member 31 and down the conical surface 49 of the stanchion before locating against the cylindrical surface 51.

Title: Apparatus for washing vehicles
IPC: B60S3/06
Filed: 1956-12-28
Abstract: 806,075. Cleaning vehicles. GIOVANNINI, C. Dec. 28, 1956 [Jan. 27, 1956], No. 39535/56. Class 138(1). Apparatus for washing vehicles comprises two vertical rotatable brushes 29 each having two supporting arms 16, 24 carried by a rotatable inner column 3 which is also movable vertically and is disposed within an outer column 2 having a helical guideway (9, 10) (see Fig. 3 not shown) in which slides a bolt 27 connected to and supporting the inner column, the direction and slope of the guideway being such that the weight of the brush causes rotation of the inner column in such direction as to push the brush into contact with the wall of a vehicle to be washed. Fig. 1 shows such a brush unit, between two of which a vehicle passes parallel to the arms 16, 24, the latter arm being a set of leaf springs. A flexible disc 20 serves as a universal joint between the driveshaft 30 and the axle 31 of the brush, allowing deviations of the axle from the vertical. An electric drive motor 13 is carried on the head 12 of column 3, the head being joined to column 2 by a bellows 15. In operation a mains electric switch (not shown) actuates a valve to admit compressed air at 7 into the cylinder 5 so raising piston 4 and column 3 (some 1/10 m.m.) until the bolt bearings contact the upper size 10 of the guideway. This allows withdrawal of a locking pin from holes 11, which pin is inserted in an electro-switch-box to supply current to the " on " base contact, tripping of which by a vehicle wheel automatically operates the plant. Compressed air leaves the cylinder 5, column 3 moves down and rotates by reason of the interaction of bolt 27 in the helical guideway (9, 10) to swing brush 29 in towards the vehicle, and wash-water is sprayed from nozzles 23. Fine adjustment means in the compressed air control enable the pressure of the brush against the vehicle to be regulated ; whilst the water supply may be controlled by the relative position to each other of the two columns so as to flow only when the brush is swung in. The motor 13 can also be made to operate at this position, or directly through the base contact, to rotate the brush in a direction opposite to the motion of the vehicle. After cleaning the vehicle trips an " off " base contact and the sequence is reversed. A guard plate 22 has rubber segments on one side for wiping off remaining water. The plant may be operated manually instead of by the vehicle.

Title: A method for improving the textile processing of artificial fibres and threads derived from polyesters
IPC: D06M11/53
Filed: 1957-12-20
Abstract: To facilitate textile processing, fibres and threads of polyesters are treated with an aqueous solution containing 0,5-10% by weight of an alkali metal salt of a weak acid, rinsed with water and dried.  A weak acid is defined as one having a dissociation constant at 20 DEG C. not greater than 10-9, and in the case of an acid having more than one hydrogen ion, the dissociation constant of the last hydrogen ion is meant. Preferably, a salt of an inorganic acid is used, and specified salts include sodium borate and carbonate, trisodium orthophosphate, and sodium sulphide, silicate, and stearate.  The treatment solution may be held at above 60 DEG C. and may also contain a surface-active compound, particularly 0,2-0,8% by weight of an anionic surface-active compound.  A number of surface-active compounds are specified.  Preferred treatments comprise (a) at least 5 mins. at 70 DEG C. to 80 DEG C. with a solution of 0,5-2,0% by weight sodium carbonate and 0,5% by weight of sodium stearate, (b) at least 2 mins. at 90 DEG C.-95 DEG C. with a solution of 3-6% by weight trisodium orthophosphate and 0,2% by weight of a sulphated secondary alcohol having 12 carbon atoms in the molecule, e.g. "Teepol" (Registered Trade Mark).  Treatment may be applied before or after any heat-treatment of the polyester fibres.ALSO:To facilitate carding and combing, fibres and threads of polyesters are treated with an aqueous solution containing 0,5-10% by weight of an alkali metal salt of a weak acid, rinsed with water and dried.  Such treatment reduces the tendency of fibres to get caught in the needles of the card or the combs of the combing machine, and reduces breakages in winding and twisting.  The treatment liquid may be applied by immersion of the fibres in the liquid, spraying liquid on the fibres, or pressing the liquid through the fibres, and may be applied before or after any heat-treatment of the fibres.  A weak acid is defined as one having a dissociation constant at 20 DEG C. not greater than 10-9, and in the case of an acid having more than one hydrogen ion, the dissociation constant of the last hydrogen ion is meant.  Preferably, a salt of an inorganic acid is used, and specified salts include sodium borate and carbonate, trisodium orthophosphate, and sodium sulphide, silicate and stearate.
