Abstract: 655,914. Bearing bushes. DEBROCK, M. L. Oct. 12, 1948, No. 26532. [Class 12 (i)] [Also in Group XXII] A bearing bush &c. is made by shaping a bronze blank with flaring projections on one face, casting on this face a more fusible metal, e.g. aluminium or an alloy thereof, casting antifriction metal on the other face and trimming. The bronze part 1 with projections 2 may be made by casting, the minimum crosssection of the projections being about 10 sq. mm., but may be increased to 50 e<SP>2</SP>, where e is the thickness of the part 1. The height of each projection should not exceed 10e. The projections may be of circular cross-section. The composite casting 1, 3 may be machined and worked and then the antifriction metal is cast on the other face of the bronze part.

Abstract: 1394579 Insulated pipes ROCKWOOL AS 7 June 1972 [8 June 1971] 26567/72 Heading F2P A metal pipe for hot fluids is insulated by covering it with a water impermeable mantle and covering the mantle with a mineral wool insulation material which has a steam diffusion resistance factor between 1 and 5. Such insulation may become saturated in wet soil but quickly dries when the soil water is removed. As shown a steel pipe 2 has a polypropylene mantle 4 spaced therefrom by cylindrical steel spacers 3, a mineral wool insulation layer 5 being left uncovered. Alternatively the mantle may be of asbestos cement and the insulation may be of glass wool, rock wool or slag wool.

Abstract: Green wool dyes are obtained by causing a compound of the anthraquinone series containing in 1 : and 4 : positions substituents which are replaceable by imino-radicals (for instance, halogen-, hydroxy-, alkoxy- or nitrogroups) to react with 4-aminodiphenyl, a homologue or substitution product thereof, containing no further amino group, and sulphonating the products thus obtained.  According to examples quinizarin with leucoquinizarin, 1 : 4-dichlor-anthraquinone, 1 : 4 - dichloro - 5 : 8 - dihydroxy anthraquinone, and 1 : 2-benzo-5 : 8-dichloranthraquinone, are condensed in presence of agents such as boric acid, and sodium acetate with 4-aminodiphenyl, quinizarin, &c. with 3-methyl-4-aminodiphenyl and 4<1>-chloro-4-aminodiphenyl, and 1 : 4-dichloroanthraquinone with 4 - aminodiphenyl - 4 - carboxylic ester (obtainable by nitrating the 4<1>-ester, separating the 4-nitro compound and reducing), and the products sulphonated by customary methods.

Abstract: 1,007,352. Strap tensioning device. STANLEY WORKS. July 1, 1964 [Sept. 10, 1963], No. 27126/64. Heading F2G. A strap tensioning tool 10 comprises a base member 12, a column 20 supporting a tensioning wheel 28, operated by lever 30 and a tensioner member 34, situated between the wheel and the base member. The strap passes between the tensioner member 34 and the base 12, where it is gripped by teeth on the base, around a package to be strapped and back between the wheel 28 and the tensioner member 34. The member 34 has a concave surface 66 facing the wheel and of approximately the same radius of curvature as the wheel and is of semi-rigid material. In operation the wheel 28 is forced down to grip the strap between the wheel and member 34 and between member 34 and the base 12. Depression of the lever 30 rotates the wheel and tensions the strap, the shape of member 34 allowing an increase area of contact between the wheel and the strap. When the strap is sufficiently tensioned a seal 46 is attached to it and the strapping is cut at severing station 36.

Abstract: 865,538. Retractive switches. BONNELLA & SON Ltd., D. H. Aug. 28, 1958 [Aug. 28, 1957], No. 27146/57. Class 38 (5). A switch arranged to be mounted in a vehicle gear lever has a ring-shaped contact surrounding a second contact, one of the contacts being fixed and the other movable laterally in any direction relative thereto to close the contacts against the action of a centralising coil spring. In one form, Fig. 1, the ring contact 12 is carried by a fixed metal sleeve 6 and co-operates with a contact 14 carried by the movable part 16 of the gear lever. The contact 14 is fixed to a rod 32 passing through a plate 28 mounted in a cap 18 of the part 16, a spring 38 being arranged between the plate 28 and a shoulder 40 on the rod 32. The part 16 has an annular shoulder 22 located in a recess 24 of the sleeve 6. A spring 30 normally holds the part 16 and sleeve 6 and thus the contacts 12, 14, separated, but tilting movement of the part 16 in any direction closes contacts 12, 14, further movement of the part 16 after the contacts have closed being made possible by the resilient mounting of contact 14. In a modification, Fig. 2, the contact 14 can be moved axially into engagement with the base of the contact 12 against the action of a light spring 44. Transverse movements are opposed by a stronger spring 30 which bears at one end on a slide 46 on the sleeve 6, which slide is axially movable to prevent spring 30 from opposing axial movements of contact 14. Specification 865,539 is referred to.

[Class 75 (i)] '  To enable the oil supplied to the combustion zone of a boiler, water heater &c. to be varied within wide limits an oil burner provided with a spraying nozzle delivering a jet of variable angle is used and means are provided for catching part of the jet and returning it to the fuel tank without entering the combustion zone. Fig. 1 shows a water heater in which the angle of the jet from a burner nozzle 19 is varied by a stem 20 operated through a flexible cable 22 by a heat'sensitive member 8 in the hot water space. A variable amount of the oil sprayed is caught by a drum 23 and housing 24 and is returned by a pipe 26 to the fuel tank 9. Oil is supplied to the nozzle 19 by a pump 11 which together with a fan 13 is operated by an electric motor 12 the circuit to which is interrupted by a heatsensitive member 7 in the outlet for the combustion gases when their temperature falls below a certain value. The burner apparatus is mounted in a housing 17 secured in a opening in the water heater. Fig. 6 shows a suitable construction of spraying nozzle comprising a whirling chamber 84 formed between two discs 85, 86 secured by a collar 87 to the nozzle body 82, the disc 86 being formed with a spraying orifice 100 and the disc 85 with a central bore  83 and with a tangential slot 89 and eccentric bore 88 communicating with the chamber 84. Oil is supplied from a chamber 78 through pipes 79, 91 to both bores 83, 88, the relative amounts being varied to vary the spraying angle by plungers 92, 93 attached to a pivoted crosspiece operated by the cable 22. Fig. 9 shows another construction in which a valve 105 can be adjusted so that all the fuel supplied by a pipe 102 can be caused to pass through a tangential duct 112 to a whirling chamber 111 in the nozzle plate 108 formed with a spraying orifice 110 or part can be allowed to escape radially from an annular chamber 104 through the space between the valve 105 and the plate 108. Fig. 2 shows a nozzle 27 of adjustable spraying angle carried by a fuel supply tube 31 supporting a housing 30 formed with air inlets 32. The housing 30 carries a drum 33 formed with an oil-catching groove 35 communicating with a return conduit 36. A plate 37 connected by radial or inclined vanes 38, 39 to the drum 33 and burner housing 27 directs a portion of the air towards the oil jet. In another construction the housing on the fuel supply tube is provided with an apertured front wall or an iris diaphragm to catch part of the oil sprayed.

The diaphragm 2 is of natural or synthetic rubber and secured to a housing 1 by a ring 11 engaging a recess in the housing, the diaphragm separating an oil filling 5 from a gas filling 6. A supporting cap 7 is embedded in the diaphragm and has a protruding boss 9 engaging a recess 3 in a plate 8 carried by the spring 4 whereby rotary movement of the plate upon compression of the spring is not transferred to the diaphragm. The material of the spring decreases in width from the small to the larger diameter end, and the corners of the strip are rounded and the telescopic turns biased towards one another to reduce abrasion of the diaphragm. The lower end of the spring may be located in a recess which prevents its diameter increasing during compression. In another embodiment in which the diaphragm is not rotatably mounted on the spring plate, the end of the spring remote from the diaphragm is provided with a ball or roller bearing between a supporting surface and a plate on the end of the spring.
