IPC: C09B44/10
Filed: 1963-04-02
Abstract: The invention comprises basic monoazo dyes of formula <FORM:0972956/C4-C5/1> wherein R is an alkyl radical which may be substituted, X is a divalent atom or group which makes up a 5- or 6-membered aromatic ring, the heterocyclic system, which may have fused rings containing, if desired, substituents, A is a phenylene or naphthylene radical, Y is a D 2-pyrazolinyl-(1) radical which may be substituted, n is 0 or 1 and E is the equivalent of an anion. The dyes are prepared by (a) reacting a heterocyclic hydrazone or benzenesulphonylhydrazone of formula <FORM:0972956/C4-C5/2> wherein B is a hydrogen atom or a benzenesulphonyl radical in the presence of an oxidizing agent with an arylpyrazoline of formula H-A-Y or (b) by alkylating a dye of formula <FORM:0972956/C4-C5/3> The dyes may be used to colour silk, leather, furs, hair, mordanted cotton, synthetic polyamides and cellulose esters but are preferably used to dye and print textile materials of polyacrylonitrile or polydicyanoethylene in blue shades.  Dyes having as heterocyclic ring systems benzthiazole, thiadiazole, thiazole, quinoline, triazole and indazole are specified in examples.  Specifications 782,310 and 871,426 are referred to.

Class 7 (iii) [Also in Group XXVIII] The air for an air-blast injection system is compressed by a pump situated immediately adjacent the fuel nozzle, and the fuel is supplied to a part of the compressed air passage in the nozzle which narrows steadily to the nozzle-opening into the cylinder. The fuel is sprayed through passages 31 in a streamlined member 30 into the compressed air flowing through a passage 29 which decreases in cross section towards the injection orifice 28 so that the air which receives the fuel is flowing with acceleration towards the orifice 28. The air pump 19,. formed integrally with the injector nozzle and supplied with pre-compressed air from the engine cylinder or a separate compressor, has a non- return outlet valve 33 which opens at a predetermined pressure. In a modification, the piston 19 is provided with a ported skirt which controls the communication of the pump space 17 with the passage 29.

Filed: 1947-05-16
Abstract: 644,381. Testing physical qualities of materials. GLOVER, C. W. May 16, 1947, No. 13295. [Class 106 (ii)] In a machine for testing beams by bending, the load is applied intermediately by one or more hydraulic rams 13 below the beam 9 which is supported at each end on transverse rollers 4. As shown, the rollers 4 are mounted between angles 5 fixed to I-beams 2 anchored to a ferro-concrete foundation 18 by bars 24. Holes 7 in the webs of the I-beams receive a bar 8 connected by links 11 to an I-beam 10 bearing on each end of the beam 9, thus determining the span of beam to be tested. A lever-operated hydraulic jack 1 transmits fluid pressure to the plunger (not shown), of the ram 13, which passes through a hole 15 in a cross-head 16 anchored to the foundation 18. The deflection is measured by a member 27, Fig. 4, on top of the beam 9, connected by a pivoted lever 28 to a rod 31 operating the pointer of a dial 25 through a rack and pinion. A block 22, Fig. 1, may be placed over the hole 15 to adapt the machine for making a compression test on a specimen 23.

Abstract: 1,144,566. Brake servomotors. GIRLING Ltd. 29 March, 1966 [30 March. 1965], No. 13344/65. Heading F2F. In a brake servomotor, which as shown is of the vacuum suspended type, reaction or feel is transmitted directly from the diaphragm 60 to a closure member of the control valve 70, which may be of known type but is preferably as shown, of the form described in Specification 1,144,567, by a deflector plate 68, which is adapted to be deformed to a conical shape by pivoting about an annular support provided by a dished plate 78, for which purpose the deflector plate is composed of a number of rigid segments 10 carried in mutually flexing relation by a flexible or resilient support which maintains the fingers in regularly spaced and radially fixed locations so as to define a slotted plate. One embodiment of the deflector plate 68, Fig. 1, consists of two sheets of plastic secured together by radial welds 14 so as to provide pockets for the segments 10, each of which has a quasi-barbed end 18 so that, once inserted, they are retained by the pockets. In a second embodiment (Figs. 3 and 4, not shown), the pockets are formed by spot welds (28) between the two sheets of plastic which coincide with part-circular co-operating cut-out portions (26) of the segments, the welds being effected after assembly of the segments in order to retain them. In this embodiment each segment is a bent plate providing an axial flange (24). In a third embodiment (Fig. 5, not shown), the segments are bonded to one or both sides of a single sheet of plastic which is crimped in the gaps between the segments to allow deformation. A further embodiment (Figs. 6 and 7, not shown) consists of an outer ring (52) provided with inwardly directed radial tabs (56) to each of which a segment (58) is spot welded. Assembly in the case of all embodiments is simplified by having the segments joined to one another initially, i.e. they are all formed from the same circular plate by radial slotting, the centre part of the plate being cut away after mounting to form the separate inner ends 18.

Tubular members 18 at the top and bottom of the frame contain lamps 20 to illuminate the edges of the sheet 12 through openings 19. The legend may be provided directly on the front surface of the sheet 12. The inner side of the legend or its supporting sheet in front of the sheet 12 may be provided with an internallyreflecting surface to increase the illumination. In a further modification, the sheet 12 is inclined relatively to the legend or adjacent supporting- sheet to provide a construction of tapering cross section, so that some of the light from a lamp in the thicker edge of the sign is reflected to and fro between the relatively-inclined sheets from that to the opposite edge, thereby producing a very uniform illumination.
