Title: Improvements in and relating to the windings of dynamo-electric machines
IPC: H02K23/36
Filed: 1927-12-16
Abstract: 282,430. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Fran- þaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). Dec. 16, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts] Windings.-A commutator machine is provided with two or more separate windings all having elements in all of the slots and adapted to be put in parallel by the brushes, the current division between the windings when in parallel being determined by " the relative resistance of the windings taken as a whole." Fig. 2 shows a winding divided into two distinct windings designated " A " and " B " of which the sections are so arranged that " the brush short-circuits one section of the winding A passing through the slot a and returning by the slot n and one element of the winding B passing through the slot, a+1 and returning by the slot n-1 or, inversely, one element of the winding B passing through the slot a-1, and returning by the slot n+1." Fig. 4 shows a duplex winding a<1>, b<1> having four pairs of conductors per slot each having pairs of long and short pitch coils connected between pairs of segments separated by pairs of segments connected to similar long and short pitch coils of the other winding. Forms are also described in which the winding is subdivided into pairs of elements, two of each pair being connected to the same segments of the commutator. In the form shown in Fig. 5, the winding is divided into groups comprising k sections (k having the value 3 in the Figure) and the k elements of this group are placed in parallel by making them end in the same segments of the commutator; the first of these elements passing through the slot a as lead-conductor of the order k, and returning by the slot n as I-return, while the second one passes through the slot a+1 as (k-1) lead and reverts bv the slot n-1 as second return conductor; the third one passes through the slot a+2 (as k-2 lead) and returns by slot n-2 as third conductor, and so forth. This method of winding may be modified to give k distinct windings not only parallel by the brushes by designating " by a<1>, b<1>, k' the first, second, k-lead conductors ending in the same segment, and similarly with the return conductors; each segment is divided in k other ones, named in the order a, # - - #. After this we let the conductors of any given letter terminate in the segment denoted by the corresponding Greek letter."

Patent GB-757970-A (GB)
Title: An improved method of producing half stuff, which is capable of being bleached, from the wood of coniferous and deciduous trees
IPC: D21C1/10
Filed: 1954-11-29
Abstract: Half-stuff is produced from wood by first subjecting the wood chips or pieces to vacuum and then treating with a weakly alkaline sodium sulphite solution at 100-140 DEG  C. under a pressure of at least 6 atmospheres under such conditions that the evolution of steam within <PICT:0757970/IV(a)/1> the capillaries of the wood is avoided, after which the material is defibrinated.  The subjection to vacuum, which facilitates penetration of the sulphite solution, is preferably conducted at a vacuum of 710-750 mm. of mercury and lasts at least half an hour. It is effected in a boiler and the vacuum is maintained whilst the treating liquid is introduced, thereafter the liquid is heated by indirect means and pressure applied by a pump.  The pump is of an oscillatory type, e.g. a piston pump, so that a pulsating pressure is communicated to the treating liquid, which facilitates its penetration into the wood.  The treating liquid is a solution of sulphite containing 100-200 gms. of sodium sulphite per litre as is made weakly alkaline, e.g. with a pH value of 7.5-8.5.  At the end of the treatment, the liquid is drawn off and the wood may be washed. If the wood is in the form of sticks it is allowed to lie in a moist condition for at least 24 hours and is then ground; if the wood is in the form of chips, penetration of the treating liquid is better and the treated chips are ground straight away. Grinding is effected at about 70 DEG  C. in a refiner. the material then being graded and dehydrated.  It may be bleached if desired with hypochlorite, peroxides, or other known bleaching agents.  A suitable apparatus comprises a boiler 1 having pressure gauges 8, 81, thermometer 9, indirect steam heating pipe 11 and safety valve 10.  15 is a water supply pipe.  The wood pieces are introduced through manhole 2, which is then sealed.  Air is extracted through valve 31 by pump 4.  At the end of half an hour's subjection to vacuum, valves 611 and 20 are opened to draw in treating liquor from tank 5.  Heat is applied by steam pipe 11 until a temperature of 115-140 DEG  C. is reached and a pulsating pressure by triple-piston pump 7 until a pressure of e.g. 10 atmospheres is reached, the pressure oscillating between 9.9 and 10.1 atmospheres.  After 2-5 hours, the pump is stopped, treating liquor drained back to tank 5 for re-use and the wood washed with water from pipe 15.  After grading, e.g. on rotary sieves or vibratory screens, and dehydrating, the yield is 80-90 per cent.

The bed temperature is controlled by the ratio of the amount of steam with respect to the amount of oxygen bearing gas that is introduced thereto and the steam &c. inlet may be separate from that of the flue gas. The coke may be gas or electrically heated.

Patent GB-340099-A (GB)
Title: Improvements in or relating to sound records
IPC: G11B3/70
Filed: 1929-11-15
Abstract: A sound record comprises outer layers formed of fibres and a binder of thermoplastic material, e.g. shellac, suitable for a playing surface and a laminated core formed of fibres and a binder including hardwood pitch.  The binder of the core preferably also includes a resin having a low susceptibility to changes of temperature such as copal resin, known as manila gum, ternati gum or manila nubs.  The binder comprises preferably at least 60 per cent of the mass.  In an example, the core composition comprises 20 lbs. of kraft pulp, 5 lbs. of unbleached sulphite, 14 lbs. of ground wood, 36 lbs. of hardwood pitch, 36 lbs. of resin and 8 lbs. of rosin.  A colouring material such as carbon black may be added.  In forming the composition, the fibrous material, except 10 lbs. of the kraft pulp, are treated with six gallons of water and then kneaded with the binder, while heating, to distribute the binder over the wet fibres.  The whole mass is then, by the addition of 12 gallons of water, broken down to a watery pulp containing distributed discrete particles of fibre and binder. The rest of the kraft pulp is then incorporated with the mixture in a paper mill beater and sheets are formed on a paper machine.  Two or more of these sheets may be pressed together to form a sheet of core material.  The playing layers may have the following composition:-64 lbs. of shellac, 6 lbs. of rosin, 15 lbs. of kraft pulp, 4 lbs. of unbleached sulphite, 13 lbs. of ground wood, 20 lbs. of clay and 3 1/2 lbs. of carbon black.  Records may be made by cutting discs from the core sheet and playing sheet and uniting them by pressure and heat.  The softening point and susceptibility factor of the core binder are such that the binder will coat the fibres and unite the discs together but will not exude through to the playing surface. Alternatively discs may be cut from compound sheets comprising one, two or three core laminae and a playing layer, two of these discs being united to form a record.  Specification 339,335, [Class 140, Waterproof &c. fabrics], is referred to.
