Title: Process for achieving a uniform condition of swelling of fibrous materials during thermal treatment
Inventor: RUETTIGER WILHELM
IPC: D06P5/20
Filed: 1963-03-20
Abstract: A uniform condition of swelling in fibrous materials during a thermal treatment is achieved by carrying out the thermal treatment in a gas which does not attack the fibrous material and which contains a definite and constant amount of water vapour which is between 1 and 500 g/cu.m but does not contain any liquid water.  The gas containing a definite water vapour content may be obtained by bringing a gas which does not attack the fibres, e.g. nitrogen, carbon dioxide, combustion gases or air, into intimate contact with water or aqueous solutions whose temperature is kept constant and providing a large surface of contact between the gas and liquid phases by spraying the water of aqueous solution in fine dispersion into the flowing gas or by bubble tray columns in which the gas is forced through one or more relatively small openings into the water or aqueous solution and during ascent through the liquid, the gas bubbles absorb water vapour.  The saturation of the gas with the water vapour may be carried out at a constant temperature of between -20 DEG  and +95 DEG C.  Purified water, river water or industrial waste waters or mixtures of water with high boiling point substances, e.g. phosphoric or sulphuric acid, sodium sulphate, sodium chloride, sodium phosphate, sodium borate, calcium chloride, sodium acetate, glycols and polyglycols may be used.  After the thermal treatment of the fibrous material it may be cooled in a gas having a temperature of 10-50 DEG C. and a constant water vapour content equivalent to a relative humidity of 65-95%. The treatment may be applied to the crease proofing of cotton and regenerated cellulose fabrics with heat curable aminoplasts, formaldehyde, dihydroxy ethyl sulphone, methylol compounds of glycols, triazinones, ethylene urea and its hydroxyl or alkoxyl derivatives, propylene urea and its derivatives or acetone in the presence of alkaline, acid or potentially acid condensation catalysts, to the thermo fixation of reactive dyes on fibres, e.g. cotton, and to the dimensional stabilization of synthetic fibres, e.g. cellulose triacetate, polyamide and polyester fibres.

Title: Improvements in and relating to magnetic cores
IPC: H01F29/14
Filed: 1949-04-27
Abstract: 658,355. Transformers and inductances. BRITISH THOMSON-HOUSTON CO., Ltd. April 27, 1949, No. 11210. Convention date, May 6, 1948. [Class 38 (ii)] To obtain a magnetic core operating with a constant permeability the ferromagnetic core is made in two sections 2, 3 each having a closed magnetic circuit and providing parallel magnetic paths, with a common exciting winding 7 linking both sections and means, such as a D.C. winding 4, for magnetizing one section with a unidirectional flux, of density in the vicinity of that providing maximum permeability, such that the algebraic sum of the flux densities in the respective sections, which would be operating above and below the density providing maximum permeability, gives a constant B/H slope and hence permeability with variation of the exciting current in winding 7. When the winding 7 is excited with A.C. a further common biassing winding 8 may link both sections and be energized with D.C. of value to give a magnetizing force to each section of value half that required for maximum permeability, the magnitude of the alternating current, between positive and negative maximum values, being not more than that corresponding to the magnetizing force necessary to give maximum permeability, and hence avoid reversal of magnetization. A suitable material is 50/50 iron-cobalt alloy with the winding 4 providing a M.M.F. of two oersteds.

Filed: 1957-04-05
Abstract: 826,428. Railway stops. STRACHAN & HENSHAW Ltd. March 6, 1958 [April 5, 1957], No. 11265/57. Class 104 (2). A rail track stop-device comprises a chock member 11, pivotally mounted on a horizontal axis 16 at right-angles to the rail track 17, and adjacent the rail 17 and provided on its upper side with a surface 12 to co-operate with a wagon wheel 14 and on its underside with a cam surface 22, a cam follower 23, which co-operates with the cam surface 22, and is mounted on the end of a ram 26 arranged to be longitudinally reciprocated to cause the chock 11 to be raised and held in the elevated position when the ram 26 is moved by an hydraulic ram or thrusting device 49 to one end of its travel and to allow the chock 11 to assume a depressed position when the ram 26 is moved to the opposite end of its reciprocal travel. In the arrangements shown in Figs. 1 and 3, in which the chock 11 is held in the " normally up " or elevated position the cam follower 23 consists of a central roller 34, which engages the cam surface 22 of the chock 11, and two end roller portions 32 which run on short spaced parallel rails 33. The cam follower 23 is normally held by a spring 27 surrounding the ram 26 in the position, shown in full lines on Fig. 1, in which a heel portion 24 on the chock 11 is disposed on the central roller 34 vertically above the cam follower spindle 35 to hold the chock 11 in the elevated or wheel blocking position. The chock 11 moves to the depressed position when the cam follower 23 is moved to a position beneath the cam face 22 on the chock 11 by a rod 38 abutting the end of the ram 26 and moved by an hydraulic ram 49 through a rack 42 and quadrant 43. The stop device may be connected to or associated with other handling, controlling or moving devices so as to operate in timed relation to such devices. The hydraulic ram 49, quadrant 43 and rod 38 are mounted on a traverser 53 running transversely to the track 17 on rails 54 located in the pit 55. The traverser is associated with several wagon tracks 17 and each track is provided with a chock 11. Interlocks are provided between the hydraulic ram 49 and a' traverser 53 to prevent the hydraulic ram 49 being operated until rails 56 on the traverser 53 are in line with a wagon track 17. In an alternative arrangement, Fig. 4 (not shown), in which the chock 11 is in the " normally down " or depressed position the spring 27 normally retains the cam follower 23 in a position beneath the arcuate portion 22 of the cam surface and the hydraulic ram 49 moves the cam follower 23 to a position beneath the heel 24 of the chock 11.

Title: Improvements relating to automatic charging arrangements of electric storage batteries
IPC: H02J7/04
Filed: 1940-07-09
Abstract: 542,328. Battery charging and discharging systems. CHLORIDE ELECTRICAL STORAGE CO., Ltd., and LORD, V. A. July 9, 1940, No. 11436. [Class 38 (iv)] An automatic battery-charging system employs a relay e, f (to determine when the battery needs to be put on charge from the source X, Y) operated in accordance with the difference of voltage between the battery and a constant, or substantially constant reference voltage. In the arrangement shown in Fig. 1 this reference voltage is derived from the output leads of a rectifier a across which a stabilizing resistance may be connected. The output leads of the battery are connected in' opposition through the relay coil which may be shunted by a variable resistance. When the battery voltage reaches its lower limit the differential current through the coil e causes closure of the relay and connection of the charging source. When adequately charged, the differential voltage falls off and the relay opens taking the battery off charge but a trickle charge from the A.C. source is supplied through the coil e and its shunt resistance.

[Class 40 (iv)] A subscriber experiencing malicious calls is provided with a modified line circuit enabling him to hold an incoming call and at the same time to signal the exchange that the call is to be traced.. The subscriber's line circuit, Fig. 2, is modified by the connection of a marginal relay MA, and when the circuit tests free to a final selector. Fig. 1, and the cut-off relay K pulls up, a malicious call relay MC operates to earth connected over a winding of relay MA and the normal contact of the uniselector, and locks. Ringing relay JA connects low resistance battery RR to the marginal relay MA which operates and locks. When the called subscriber answers, ring trip relay F and relays D, E pull up, J, JA release, and the connection is completed. In the case of a malicious call the called subscriber dials and the momentary release of D operates relay CD which lights a lamp MCL and sounds an alarm at an operator's position. Should the caller hang up, A releases but guard relay B holds since its shorting circuit has been broken by MC. A howler connected to the line is used to signal the called subscriber to hang up. When connection is made to an unmodified line circuit an S, Z-pulse circuit forcibly releases the connection after a given time, unless the calling subscriber has previously hung up.
