Title: Seals between two relatively movable parts
IPC: F16J15/44
Filed: 1965-04-15
Abstract: 1,064,053. Packing rotors; vanes and abutments. BETEILIGUNGS-UND PATENTVERWALTUNGS G. m. b. H. April 15, 1965 [April 16, 1964], No. 16333/65. Heading F1F. A sealing arrangement for sealing between two relatively movable parts, e. g., for sealing in the radial or axial direction between the rotarypiston and the housing of a rotary-piston compressor, comprises a sealing strip 12, Fig. 3, of semi-cylindrical cross-section vulcanized to a rubber layer 13 which in turn is vulcanized to an insert member 10 held against rotation in a housing 8 by a pin 11. In the unsealed position of the seal a small gap 18 exists between the flat surface of the sealing strip 12 and the other or rotary part 9 through which a pressure drop occurs between two adjacent chambers at different pressures. The pressure drop is assumed to be linear from a high pressure in gap 14 to a low pressure in gap 16, so that the pressure acting on the flat surface of the sealing strip to the right of a centre plane through a line 20 is less than the pressure acting to the left of this plane. Consequently due to the resilience of the rubber layer 13 the sealing strip will pivot about the line 20 in a clockwise direction 23 to seal the right hand corner of the strip against the rotary part 9. When the gap 18 is then closed at its downstream end the pressure in the gap 18 rises to that in the gap 14 with consequential increase in the pressure to the right of the centre plane and a tendency for the seal to be broken and the sealing strip to execute an oscillating motion at high or low frequency. To overcome this the flat surface of the sealing strip may be recessed at its outer edges so that when the seal is closed sealing occurs along a line much closer to the centre plane so that even when the pressure in the gap 18 reaches that in the gap 14 the turning moment tending to unseal the seal is less than the turning moment tending to seal the seal. This results in the seal remaining in its closed position.

Filed: 1959-05-13
Abstract: A synthetic resin is prepared by heating together at the boil a mixture of water, aqueous formaldehyde solution, sodium hydroxide, benzoguanamines, melamine and thiourea.  After filtering, water and isopropanol are added and the whole maintained at 87 DEG  C. and pH9 for 4 hours 20 minutes.  The product is used for laminating (see Group VIII).ALSO:A synthetic or cellulose ester fibrous material, for use in a laminate (see Group VIII), is optically brightened, as follows. Acetyl-cellulose or polyamide fibres may be brightened with quaternary oxacyanine derivatives of the formula <FORM:0883486/IV (c)/1> in which A1 and A2 represent each a benzene or naphthalene residue, R1 and R2 represent each an alkyl or hydroxyalkyl group and X represents the radical of a strong acid.  Polyamide fibres may be brightened with 1 : 3 : 4-oxdiazole compounds.  Polyacrylonitrile fibres may be brightened by treatment in an aqueous bath with a dibenzimidazyl compound of the type <FORM:0883486/IV (c)/2> which is free from groups imparting solubility in water, and in which formula R1 is a bridge member containing at least one C=C group in conjugation with the double bonds of the imidazole rings, e.g. para-phenylene, 2-5-furylene, or an ethylene bridge, and the benzene rings R may contain substituents, e.g. methyl, methoxy or chlorine. Cellulose acetate fibres and polyester fibres may be brightened with a  : b -di-[benzoxazolyl-(2)]-ethylene compounds free from groups imparting solubility in water, e.g. compounds of the formula <FORM:0883486/IV (c)/3> in which Z1 and Z2 each represent a hydrogen atom or a methyl group.  The brightening agent may be fixed on the finished fibrous material.  In the example, a fabric of fibres of terephthalic acid-polyglycol ester is treated in a bath containing water, ammonia, and a finely dispersed paste prepared from a  : b -di-[5-methyl-benzoxazoylyl-(2)]-ethylene, and an addition product of about 30 mols of ethylene oxide with a mixture of saturated fatty alcohol, preponderantly C18.

[Class 20 (i)] A mast is formed of rigid members connected together by unions to form an articulated unit which, when arranged upright and stayed, forms a flexible mast, the unions allowing limited universal movement between the members. In one form the ends of the members 4, 5 to be joined are provided with slotted plates 7 having upstanding plugs 9 which fit the ends of the members, and these slotted plates are brought close together with a plate 10 between them. This plate is provided with double-lipped projections 11 to which the ends of the guy-ropes 16 may be hooked, the lips of the projections passing through the aligned slots 8 in the plates 7 as they are brought together, so that on rotation of the members the plates 7 are loosely locked in contact with the plate 10. A stop pin 13 prevents relative rotation of the members for unlocking. In a modification, Fig. 6, the intervening plate 45 is also slotted so that the slots therein may register with the slots in the end plates of the members 4, 5 to allow passage for the loose-lipped members 46 attached to the ends of the guy-ropes. Relative rotation between the ends of the members and the intervening plate causes loose locking of the joints. In a further modification, Fig. 8, for heavy work, the ends of the mast members 53, 52 are received in sockets 50 with a universal joint 54, 55, 56 between the sockets, the ends of the guy ropes being secured to members 59 welded to the pins of the joint.
