Title: Improvements in and relating to electric motor equipments
IPC: B60L50/30
Filed: 1943-08-05
Abstract: 568,156. Dynamo electric machines. FLETCHER, G. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Aug. 5, 1943, No. 12656. [Class 35] [Also in Group XXXVII] To reduce energy losses during braking and acceleration of an electrically-driven vehicle, the traction motors 1, 2 during braking are disconnected from the lines 5 +, 5 - and run as generators to supply accelerating current to a dynamo-electric machine 7b coupled with a fly-wheel 7a, the increase in kinetic energy of which is utilized to accelerate the motors when the vehicle is to be restarted, the machine 7b then acting as a generator driven by the flywheel. The fly-wheel machine is preferably of the metadyne type having a winding 11 for compensating secondary armature reaction and a control winding 12 for regulating the braking and accelerating currents, whilst a further winding 17, opposing the winding 12 and in series with a resistor 18 having a negative resistance - voltage characteristic, limits accelerating current as the voltage across the motors approaches the line voltage. A switch 20 closes when the motor and line voltages are equal and a winding 19 then prevents further rise of motor volts to allow the line switch 6 to be closed. Braking by the fly-wheel machine may be preceded by normal regenerative braking of the motors. In a modified arrangement, the fly-wheel is associated with a machine of normal construction, the excitation of which is controlled by a metadyne machine. The fly-wheel machine may be brought up to speed initially either by connection to the line or by utilizing the energy of the first few braking operations, the motors being started in the normal manner during this period. Specification 568.155 is referred to.

Filed: 1940-08-07
Abstract: 544,480. Intaglio printing-machines. GRIFFIN, E. G. (American Bank Note Co.). Aug. 7, 1940, No. 12703. [Class 100 (ii)] Inking apparatus.-The plate 11 of a rotary steel plate printing machine is inked by a resilient roller 16 engaging the plate under such pressure as to be deformed thereby and driven positively and indirectly from the plate cylinder so as to have a surface speed substantially equal to that of the plate. The inking roller 16 comprising a resilient cover 17, e.g. of soft vulcanized rubber, on a metal core is driven by a gear 32 from a gear 31 on a distributing drum 18 which is driven through a train 28 from a gear 12 on the plate cylinder 10. The gear 32 is removable so that, after change of diameter of the roller 16 due to regrinding, it may be replaced by one of a different number of teeth so that the peripheral speed of the roller remains unchanged. The roller 16 is mounted in slidable bearings 33 adjustable by screws 35, 36 and lock nuts 37, 38 to regulate its pressure upon the plate 16, and the drum 18 is also mounted in slidable bearings 40, adjustable by screws 42 and locknuts 43, 44, the latter of which are mounted on the screws 35. Ink is supplied to the drum 18 from a fountain roller 15 by means of a distributing roller 19 mounted in vertical slotted bearings 26 so as to rest. freely on both rollers. The roller 19 comprises a number of sleeves 22, Fig. 5, having resilient coverings 23, the covering of one sleeve overlapping the adjacent sleeve. Such a roller may be made to the length required by the width of the plate 11. The diameters of the coverings 23 may vary in accordance with the amount of ink required on the corresponding strip of the plate. The ends of the spindle of the roller 19 may be engaged by V brackets 27 adjustable vertically to raise the roller clear of the drum 18 and roller 15 for cleaning purposes. The ink film on the roller 15 is regulated by a duct blade 47 having an angular head 48 carrying adjusting screws 49 threaded through a cross bar 50 of the duct, springs 52 being arranged between the head and bar. The edge of the blade 47 is undercut at 54 and ink which drops from the edge of the blade is caught by a supplementary blade 55 which returns it to the roller 15. The edge of the blade 55 is spaced from the roller 15 a slightly greater distance than the blade 47.

Title: Improvements in or relating to methods of preparing polyaromatic resins
Inventor: BLOOMFIELD PETER RICHARD
IPC: C08G61/00
Filed: 1960-04-11
Abstract: SiX4, GeX4, SnX4, BX3, PX3, POX3, PSX3, AsX3 or SbX3 where X is a halogen atom and at least one aromatic or s-triazine di- or polyhalide having at least two Cl, Br or I atoms directly attached to the ring are treated with Li or Na metal to remove halogen with the formation of polymers.  Further, one mole of the inorganic halide may be reacted with one mole of the organic polyhalide in the presence of Na or Li, with the addition of 0-1 mole (with BX3, PX3, POX3, PSX3, AsX3 or SbX3) or 0-2 mole (with SiX4, GeX4 or SnX4) of an aryl or alkyl halide having at least one Cl, Br or I atom.  The preferred method is to mix the halides in solution, e.g. in tetrahydrofuran 1,2-dimethoxyethane or ether, to an equivalent quantity of finely divided Li or Na stirred in an atmosphere of nitrogen. Alternatively, the organic halide is reacted with the metal and then the inorganic halide added.  Low temperatures are preferred, generally -80 DEG  to 0 DEG C. When the product has halogen atoms attached to Si, Ge, Sn, B, P, As or Sb, the resin may be hydrolysed to a polymeric acid which may then be cross-linked by reaction with metal oxides.  In Example IV, a resin having chlorine attached to Si is reacted with ethanol to replace Cl by OEt.  In the Provisional Specification, it is stated that reactants described in Specification 928,576 may be used in admixture with the reactants of the present application.  Reference has been directed by the Comptroller to Specification 896,301.

Filed: 1923-05-15
Abstract: 197,937. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 16, 1922, [Convention date]. Glass, dividing.-An apparatus for cutting continuously fed glass tubes into section comprises means for bending the tube, during its travel, into contact with a cutter moving at the same speed and in the same direction as the tube, and means for breaking the tube by bending. The breaking may be assisted by suddenly cooling the tube at the point scored. The tube 3 is scored by a disc 45, revolved from a pulley 37 by an electromotor, and axially reciprocated by a cam 32 on a shaft 29, driven through gearing 28, 26 from an electromotor 27. An adjustable resilient member 57 is reciprocated across the direction of travel of the tube by a pivoted lever 54 actuated from a cam 52 on the shaft 29 and bends the tube against the disc 45 when the latter is travelling at the same speed as the tube. The scored tube passes between a resilient support 69 and a water cooled rotating disc 65 whereupon the tube is strained nearly to fracture. An adjustable rotating transverse pusher 71 driven from a shaft 7 by a chain 62 flexes the tube and completes the fracture. The tube sections fall down an inclined table 78 to a tray 77.
