Title: Trisazo dyestuffs
IPC: C09B31/22
Filed: 1952-04-22
Abstract: The invention comprises trisazo dyestuffs corresponding as free acids to the general formula:- <FORM:0710808/IV(c)/1> wherein A-N=N-B-N=N- represents the radical of a diazotized aminomonoazo dyestuff which contains at least one sulphonic acid group and in which A and B belong to the benzene series.  They may p  be obtained by coupling a diazotized aminomonoazo dyestuff of the benzene series containing at least one sulphonic acid group with 2-(4\sv aminobenzoylamino)-5-naphthol-7-sulphonic acid, further diazotizing the resulting aminodisazo dyestuff and coupling with 2-amino-5-naphthol-1 : 7-disulphonic acid.  The products yield on cotton and regenerated cellulose fibres red to blue-violet dyeings which can be diazotized on the fibre and developed with b -napthol to bluish red to reddish blue shades.  In examples, the aminomonoazo dyestuff A-N=N-B-NH2 is: (1) to (3) 1-amino-2 : 4-dimethylbenzene-6-sulphonic acid --> 1-amino-2-methoxy-5-methylbenzene, 1-amino-2:5-dimethylbenzene or 1-amino-2 : 5-dimethoxybenzene; (4) metanilic acid --> m-toluidine.

Abstract: 578,987. Landing - gear. MORANESAULNIER, (formerly AEROPLANES MORANE-SAULNIER, SOC. ANON. DE CONSTRUCTIONS AERONAUTIQUES). April 23, 1945, No. 10197. Convention date. May 15, 1940. [Class 4] A shock-absorber G carrying wheel,W is retracted from the position of use, Fig. 1., about pivot H by the action of a hydraulic jack V on an arm I rigid with the shockabsorber G, which is locked in the position of use by a strut consisting of two parts A, A<1> pivoted together at B and locked to serve as a strut by a member C, which is shown in Fig. 2 as being part of a lever L. Breaking of the strut joint is effected by control lever T being moved in direction f to open valve D for turning pivoted lever L and lock C, the further movement of lever L bringing a part R into contact with a part R<1> of strut part A<1> to raise pivot B over the dead-line to break the strut joint : movement of control lever T in direction f<2> supplies hydraulic pressure to operate jack V for retracting the landing gear. In a modification, Figs. 3 and 4, only a single movement of control lever X is required, the first result being to supply hydraulic pressure to jack V the cylinder of which, in consequence of the piston being held by the arm I of the locked shock-absorber G, acts by its closed end to open compressed air valve D for breaking the strut joints at B and allow the jack to retract the shockabsorber.

Hoods.-In folding hoods of the kind in which a single standard is pivoted at each side of the vehicle and has forward and rear extensions connected to it by links at each side, the connection to the front extension comprising two links, the linkages are arranged in various ways, as described below. The front bow c, Fig. 3, is connected to the main standard by a link b, while the intermediate bows e, which are pivoted to the first link b, are supported by a link d which is pivoted to the standard at a point above the point of the link b. The rear bow i is carried by two links l, p, the link p being prolonged by means of a slotted quadrant r engaging a pin t on the link d. In another form, the link d may be disposed below the link b, and may coact with the link p by means of toothed quadrants pivoted on the standard. The second link d may be connected to the front bow c instead of to an intermediate bow. In another form, the rear bow i may be pivoted to a rearward extension of the intermediate bow e. Where springs m housed in the standards are employed to assist the raising of the hood, the upper end of the spring is secured to the lower link, as shown.

Title: Apparatus for finishing circular cylindrical walls and bores
Inventor: THOMPSON EDWARD HERBERT
IPC: B24B39/02
Filed: 1961-03-21
Abstract: 925,385. Axial rolling. E. H. THOMPSON & SONS (LONDON) Ltd. Feb. 28, 1962 [March 21, 1961], No. 10348/61. Class 83 (4). A roller tool for finishing circular bores has a plurality of planet rollers, located in a cage, which rotate around a tapered front end of the tool such that, in operation, the rollers roll between the said taper and the bore to be finished. Rearwardly of the tapered front end 10 is a parallel portion 12 on which is journalled the cage 13. Thrust during rolling is taken on a thrust bearing 22, and during withdrawal of the tool, the rollers move forwardly to abut an end cap 35 which rotates about a screw 36 with the cage 13. Rolling thrust is transmitted from the rollers 14 to the cage 13 through single balls 28, located one in each roller. Adjustment for different diameter bores is achieved by unlocking two nuts 20, 21 and moving them rearwardly so that when the parallel lead portion of the roller 14 engages the bore, the rollers are moved rearwardly until the cage abuts the bearing 20, in which new position the rollers will be running on a larger diameter portion of the taper 10. The nut 21 may have a graduated scale used in conjunction with a pointer mounted on the tool body. Lubricant is supplied through a pipe 40 to a helical oil groove in the journal 12. Specification 892,695 is referred to.

Title: Improvements in or relating to winding layouts for dynamo-electric machines
IPC: H02K24/00
Filed: 1952-04-30
Abstract: 726,665. Selsyn machines. SVENSKA ACKUMULATOR AKTIEBOLAGET JUNGNER. April 30, 1952 [May 4, 1951], No. 10934/52. Class 35. In order to eliminate harmonics, the stator or rotor of a Selsyn or other machine has polyphase slot windings of which each phase consists of two or more coils per pole, the total number of slots is odd, and each phase includes coils of equal and different spans and with different numbers of turns. In conventional machines, the slots are symmetrically arranged so that several slots occupy similar positions with respect to the rotor at the same time. As a result of the unsymmetrical disposition of the coils according to the invention, each coil side occupies a distinctive position and the machine behaves as regards harmonics as if it had four times as many slots, i.e. the actual number of slots multiplied by the number of edges of the poles of the other member. When the invention is applied to both stator and rotor, the slot numbers should be chosen so that their least common multiple is as great as possible. As shown, applied to the stator of a machine with a salient pole rotor, the stator 1 has five slots A, B, C, D, E accommodating two phases. The first phase consists of coils 3, 4, 5, 6 having a magnetic axis 7-7, the number of conductors in each slot being advantageously made proportional to the sine of its distance from the phase centre. The other phase comprises similarly disposed coils having a magnetic axis 8-8. If the number of phases is odd, the number of slots must be a multiple of the number of phases and skewed slots or pole-tips may be used. The invention may be applied to A.C. generators and motors.
