Title: New textile colouring process
IPC: D06P3/24
Filed: 1957-10-04
Abstract: Textile materials of polyamides or modified polyacrylonitrile are dyed or printed with an aqueous dispersion of a water-insoluble azo dyestuff containing at least one alkoxy or alkyl-amino radical which is substituted on a carbon atom or atoms thereof by an epoxy group or by a chlorine or bromine atom, or by a hydroxy group and a chlorine or bromine atom, the diazotisable amine from which the dyestuff is derived containing not more than one nitro group.  Dyeing may be effected at temperatures up to or above 100 DEG C.  Printing may be effected with a paste thickened with methyl cellulose, Nafka crystal gum or sodium alginate and containing the usual adjuvants such as urea, thiourea, thiodiglycol, methylated spirits, sodium-mnitrobenzenesulphonate and aqueous emulsions of sulphonated oils, the prints being dried and finally steamed.  The dyestuff is added to the dyebath or printing paste, together with the usual dispersing agents, as an aqueous dispersion or as a re-dispersible powder.  Dyeings or prints thus obtained with a dyestuff containing a primary amino group may be further diazotised and coupled on the fibre.  The dyestuffs may be obtained from diazotised aromatic amines and coupling components which are free from sulphonic- and carboxylicacid groups but which are so-chosen that the resultant dyestuffs contains at least one of the above specified groups such as b - chloroethoxy, b - bromoethoxy, b -chloropropoxy, b - bromopropoxy, g - chloro -b -hydroxypropoxy, g - bromo -b - hydroxypropoxy, b -g -epoxypropoxy, b - chloroethylamino, b -bromoethylamino, b - bromopropylamino, b -chloropropylamino, g - chloro -b - hydroxypropylamino, g - bromob - hydroxypropylamino, b -g -epoxypropylamino, N : N- di- (b -chloroethyl)-amino, N : N- di(b - bromoethyl) amino, N : N-di- (g - chloro -b  - hydroxypropyl) amino, N : N-di (g - bromo -b - hydroxypropyl)- amino, N : N-di-(b  : g - epoxypropyl) amino, N -b - chloro-ethyl -N- b - methoxyethylamino, N -b - bromoethyl -N- ethylamino, N- g - bromo -b -hydroxypropyl -N -b  -cyanoethylamino, N -b  -g  -epoxypropyl -N -methylamino, N- g - chloro b - hydroxypropyl -N -b  -ethoxyethylamino and N- g -chloro -b - hydroxypropyl -N -b -hydroxyethylamino groups.

Title: Improvements relating to impulsive driving mechanisms for ignition magnetos
IPC: F02P1/00
Filed: 1921-10-27
Abstract: 186,848. Watson, E. A., and M.-L. Magneto Syndicate, Ltd. Oct. 27, 1921. Magnetos, driving.-In an impulsive driving- mechanism for ignition magnetos, the catch for intermittingly engaging one of the members is magnetically operated. In one construction, a member a, Figs. 1 and 3, secured to the driving- element, is coupled by a spring e to a member b secured to the magneto shaft. On the member a is transversely arranged an iron bar f adapted to attract a stationary lever consisting of two permanent magnets h against the action of a spring q. The lever engages a projection i and thus arrests the member b, and is afterwards disengaged by a cam l co-operating with a non-magnetic roller k. Two cams l and two bars f are employed if two impulses are required in each revolution. In a modification, the lever is of iron and the magnets are secured to the member a. Fig. 5 shows a further modification in which the members a, b are locked by means of a ball f operated by a magnet h and released by means of a cam l and push-rod k operating through a magnetic portion h<1>.

Filed: 1920-10-09
Abstract: 152,683. Cordes, H. G., (Assignee of Libby, T. M.). Oct. 21, 1919, [Convention date]. Duplex wireless signalling.-In a wireless receiving system, one or more pairs of circuits in parallel 10, 11 and 12, 13, Fig. 4 are connected in series with the aerial circuit 2, 3, the reactance X of the aerial circuit being adjusted to equal reactance Y of the circuit 10, 11, and both being zero for the received signal frequency. The reactance Z of the circuit 12, 13 is adjusted so that the reactance of the circuit 10, 11, 13, 12 is zero for the interfering frequency. The reactance of the whole is X + Y-Z/Y+Z which is zero if X and Y are zero and infinite when Y + Z = zero. Circuits 14, 15 and 16, 17 are similarly adjusted for suppressing a second interfering wave. The circuits 2, 3 and 10, 11 are calibrated in wave lengths, circuit 12, 13 having arbitrary graduations corresponding to given wave lengths of the former circuits. The ohmic resistances are minimized by using continuous conductors of large surface, and air condensers are used. The Specification as open to inspection under Sect. 91 (3) (a) also shows the invention applied to duplex working, Fig. 5 (Cancelled). Circuits 2, 3 and 10, 11 and 14, 15, 17 are tuned to one wave length and circuits 2, 23 and 14, 15 and 10, 11, 12 to the other, coils 5 and 25 being parts of ordinary receiving or transmitting sets. In a modification coil 5 is connected to a receiver. and coil 25 to a transmitter, circuit 14, 15, 17 being omitted. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for measuring the time taken for a change to occur from or to the fluid state of a material or medium
IPC: G01N33/49
Filed: 1976-07-09
Abstract: 1508946 Measuring rheological properties of fluids A GIROLAMI 9 July 1976 [16 July 1975] 28634/76 Heading G1S An apparatus for measuring the time taken for a change to occur in the physical state of a fluid e.g. clotting in blood, comprises at least one jar 1, Fig. 7, the bottom of which serves as a circular track for a ball 2, a support 4 holding the jar or jars inclined, and means 6-10 for rotating the jar, the time taken for a clot to form in the fluid within the jar and carry the ball up to the inclined bottom of the jar being noted either automatically or by the operator. In Figs. 3 and 4 the jar 1 and support 4 are transparent so that the clot C when formed by a reagent added to the fluid entrains and moves the ball to a position where for example it occults a light from beam S-R and causes a timer control pulse to be made or causes an electric or magnetic field to be changed to operate a detection system. In a modification, Figs. 5 and 6 (not shown) the support 4 is opaque and the light beam is obstructed by the ball but the support is provided with apertures (4a) for the passage of the beam when the ball is carried round. In Fig. 8 (not shown) a plurality of jars are rotated simultaneously or independently with a detection system for each jar controlling a timer and a pilot lamp. Moreover, a number of temperature controlled cavities designed to take jars are provided so that several tests can be made at the same time. It is also possible for a test to start with a thick viscous medium which becomes fluid and releases the ball to a low position. In the prior art a cylindrical ferromagnetic component movable within a container for the fluid under test is held close to an external magnetic field detector. When the viscosity of the liquid increases however the adhesion between the inside wall of the container and the component overcomes the force maintaining the component adjacent the detector and indicates the change of state of the fluid.

Title: Improvements in the treatment of cellulose derivatives
IPC: D01F2/28
Filed: 1930-09-24
Abstract: Cellulose acetates and other organic esters of cellulose of substantially uniform ester content, particularly acetone-soluble cellulose acetates, are separated into constituents more uniform as regards their solubilities, resistance to heat, viscosity characteristics &c. by subjection to fractional extraction.  The liquids used for the extraction are preferably non-solvents for the main bulk of the esters or at least for the portion of higher viscosity characteristics; with acetone-soluble cellulose acetates, chloroform, dichlorethylene and other chlorinated hydrocarbons are suitable extracting agents.  In an example, an acetone-soluble cellulose acetate is repeatedly extracted with warm chloroform to give a product producing solutions of improved clarity.  The fractionated products are by reason of their improved clarity and uniformity suitable for the manufacture of artificial filaments and yarns, films, laminated glass, lacquers, plastic masses, and moulding powders.

Patent GB-340307-A (GB)
Title: Improvements in domestic irons
IPC: D06F75/26
Filed: 1929-09-25
Abstract: 340,307. Hand-irons. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. Sept. 25, 1929, No. 29095. [Class 138 (ii).] A hand-iron is provided with control means which are actuated to supply the heating medium when the handle is grasped during use in the normal ironing position and cut it off when the handle is released and the iron left in ironing position and which either maintain the supply or cut it off according to which of two positions a supporting lug occupies when the iron is placed on end temporarily out of use. The control means may actuate a switch for an electric heating element or a tap for a gas-iron provided with a by-pass or spongy platinum igniter. In Figs. 2 and 2B a sliding member 5 carrying a switch blade 8 is biassed by a spring 10 to the position shown wherein the circuit of the heating element is broken between two fixed contacts 8a. When the handle is grasped the contacts 8a are bridged by the blade 8, the sliding member 5 being moved by actuation of pivoted keys 17, 18 in the handle lever 13 and the pin and slot connection 11, 12. Stops 9 limit the movement of the sliding member. When the iron is placed on end with a pivoted lug 7 in the full line position, Fig. 3, the spring 10 moves the sliding member 5 to break the circuit. When the ug which is pivoted to the sliding member 5, is placed in the broken line position the weight of the iron maintains the blade 8 in bridging engagement with the contacts 8a against the spring 10 to maintain the circuit. In Fig. 4, the forward end of the sliding member 5 is pinned to a lever 19 against the cam end 20 of which bears a spring 21 which is freely mounted on a pin 22. A sleeve 22a slidably mounted on the other end of the pin is provided with a knife-edge which engages in a recess in a switch blade 23 which co-operates with fixed contacts 21. Limit pins 25, 26 for the switch blade are provided, and a pin 19a on the lever 19 engages a recess la in a distance-piece 1b to prevent the spring 10 from drawing it back too far. In Fig. 5, an ordinary tumbler switch 28 is connected to the key pivoted in the handle through a lever 29 which may be provided with means permitting lost motion. The lever 29 is provided with a bifurcated member 32 extending rearwardly through apertures in fixed lugs 33 and provided with springs 35 between the lugs and the enlarged ends 34 of the limbs of the member 32. When the iron is placed on end with a pivoted lug 7 parallel to the limbs of the member 32 the springs 35 maintain the switch off, but when the lug is swung to the position shown in Fig. 7, the weight of the iron moves the bifurcated member through the lugs 33 against the springs 35 and closes the switch.
Patent GB-897536-A (GB)
Title: Improvements in or relating to timing mechanisms
IPC: G04C23/16
Filed: 1958-09-11
Abstract: 897,536. Electric timers. INTERNATIONAL REGISTER CO. Sept. 11, 1958 [Oct. 14, 1957], No. 29182/58. Class 38 (5). An electric timer for a cooker &c. has two concentric discs visible in part through windows 35, 45, the first indicating the stop time for the timed operation, the second being an " hour to cook " indication knob 28 sets stop time and is first pulled out to switch to " auto " and then rotates the dial. Then knob 38 is pulled out to set the cooking time. An interval timer 22 is also provided. The mechanism, which is fully disclosed in the Specification, consists eventually of a series of coaxial discs, one of which is driven by an electric clock through a gear train, interengaging to operate a cam which makes and breaks the circuit. By providing suitable indications on the visible parts of the switch it is claimed that the setting procedure is self-winding without the need for explanatory matter. The dial 140 carries the operating instructions appearing in the windows 35 (" manual " or " push to manual ") and 45 ("oven on" or "oven off") and reveals discs 160 (" hours to cook ") 155 (" stop time ") at the appropriate places in the setting sequence. The disc 190 is driven by the clock train 129 and discs 180 and 170 are the cooking time trip and stop time trip respectively. The operation is as follows. Pulling out knob 28 moves dial 140 to reveal the stop time which is thus adjusted by rotating the knob which rotates both the cook trip dial 180 and the stop trip dial 170 whilst leaving the " hours to cook " dial 160 stationary. Stopping is initiated when the lug 173 is engaged by lever 194 on the time disc, a motion being imparted to the sun gear 200 and planet gear 197 to operate the switch tripping arm 265. The " hours to cook " time is set by pulling out knob 38 and rotating the knob to displace the " hours to cook " trip 180 and " cooking hours " dial 160, the stop time trip 170 remaining stationary. At the appropriate time lug 183 is engaged by lever 194 to rotate the sun and planet gearing and thus the cam 138 to engage the switch mechanism. As set forth above, the subsequent movement of the cam by lug 173 through arm 265 again moves the cam to the " off " position.
